Comparison of four different collateral scores in acute ischemic stroke by CT angiography

Purpose: Multiple scores have been described for the assessment of collateralization in acute ischemic stroke. Currently, there is no gold standard for collateral assessment by CT angiography (CTA). This study compared four frequently used collateral scores with regard to their correlation with early infarct core and mismatch ratio. Methods: 30 consecutive patients with acute occlusion of the M1 segment or terminal carotid artery were reviewed retrospectively. Collaterals were assessed using dynamic and also single-phase CTA according to grading systems by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR), Alberta Stroke Program Early CT Score (ASPECTS) (on collaterals), Christoforidis et al and Miteff et al. The Christoforidis and ASITN/SIR scores, which were initially designed for conventional angiography, were adapted to be applicable to CTA. The scores were compared with respect to early infarct core and mismatch ratio in perfusion CT estimated by RAPID software using Spearman correlation. Results: ASITN/SIR and ASPECTS collateral scores showed good correlation with early infarct core (rho=-0.696, p<0.001 and rho=-0.677, p<0.001) and mismatch ratio (rho=0.609, p<0.001 and rho=0.581, p<0.001). In contrast, the Christoforidis and Miteff scores correlated less well with infarct core (rho=0.245, p=0.191 and rho=-0.272, p=0.145, respectively) and mismatch ratio (rho=-0.329, p=0.075 and rho=0.279, p=0.135, respectively). ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion.

ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion. 2015 Potreck, Arne verfasserin (DE-588)1031679790 (DE-627)737108886 (DE-576)379370638 aut Möhlenbruch, Markus Alfred 1979- verfasserin (DE-588)137693591 (DE-627)594845041 (DE-576)304845655 aut Bendszus, Martin verfasserin (DE-588)1032676426 (DE-627)738634131 (DE-576)175567697 aut Pham, Mirko 1978- verfasserin (DE-588)132435241 (DE-627)522697763 (DE-576)252667034 aut Enthalten in Journal of neuroInterventional surgery London : BMJ Journals, 2009 8(2016), 11, Seite 1116-1118 Online-Ressource (DE-627)605217548 (DE-600)2506028-4 (DE-576)308906721 1759-8486 nnns volume:8 year:2016 number:11 pages:1116-1118 extent:4 http://dx.doi.org/10.1136/neurintsurg-2015-012101 Verlag Resolving-System Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_62 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_120 GBV_ILN_121 GBV_ILN_150 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_374 GBV_ILN_602 GBV_ILN_647 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2057 GBV_ILN_2064 GBV_ILN_2093 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2119 GBV_ILN_2129 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2472 GBV_ILN_2522 GBV_ILN_2893 GBV_ILN_2992 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4277 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4336 GBV_ILN_4346 GBV_ILN_4367 GBV_ILN_4393 GBV_ILN_4753 AR 8 2016 11 1116-1118 4 2013 01 DE-16-250 2986427731 00 --%%-- --%%-- --%%-- --%%-- l01 06-11-17 2013 01 DE-16-250 00 s hd2016 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_5 2013 01 DE-16-250 03 s s_4 2013 01 DE-16-250 04 p (DE-627)149617481X Seker, Fatih 2013 01 DE-16-250 04 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1565063945 Potreck, Arne 2013 01 DE-16-250 05 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 2013 01 DE-16-250 06 p (DE-627)1501228323 Möhlenbruch, Markus Alfred 2013 01 DE-16-250 06 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 06 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 06 s pos_3 2013 01 DE-16-250 07 p (DE-627)1450183360 Bendszus, Martin 2013 01 DE-16-250 07 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 07 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 07 s pos_4 2013 01 DE-16-250 08 p (DE-627)147292407X Pham, Mirko 2013 01 DE-16-250 08 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 08 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 08 s pos_5

Currently, there is no gold standard for collateral assessment by CT angiography (CTA). This study compared four frequently used collateral scores with regard to their correlation with early infarct core and mismatch ratio. Methods: 30 consecutive patients with acute occlusion of the M1 segment or terminal carotid artery were reviewed retrospectively. Collaterals were assessed using dynamic and also single-phase CTA according to grading systems by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR), Alberta Stroke Program Early CT Score (ASPECTS) (on collaterals), Christoforidis et al and Miteff et al. The Christoforidis and ASITN/SIR scores, which were initially designed for conventional angiography, were adapted to be applicable to CTA. The scores were compared with respect to early infarct core and mismatch ratio in perfusion CT estimated by RAPID software using Spearman correlation. Results: ASITN/SIR and ASPECTS collateral scores showed good correlation with early infarct core (rho=-0.696, p<0.001 and rho=-0.677, p<0.001) and mismatch ratio (rho=0.609, p<0.001 and rho=0.581, p<0.001). In contrast, the Christoforidis and Miteff scores correlated less well with infarct core (rho=0.245, p=0.191 and rho=-0.272, p=0.145, respectively) and mismatch ratio (rho=-0.329, p=0.075 and rho=0.279, p=0.135, respectively). ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume.

This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion. 2015 Potreck, Arne verfasserin (DE-588)1031679790 (DE-627)737108886 (DE-576)379370638 aut Möhlenbruch, Markus Alfred 1979- verfasserin (DE-588)137693591 (DE-627)594845041 (DE-576)304845655 aut Bendszus, Martin verfasserin (DE-588)1032676426 (DE-627)738634131 (DE-576)175567697 aut Pham, Mirko 1978- verfasserin (DE-588)132435241 (DE-627)522697763 (DE-576)252667034 aut Enthalten in Journal of neuroInterventional surgery London : BMJ Journals, 2009 8(2016), 11, Seite 1116-1118 Online-Ressource (DE-627)605217548 (DE-600)2506028-4 (DE-576)308906721 1759-8486 nnns volume:8 year:2016 number:11 pages:1116-1118 extent:4 http://dx.doi.org/10.1136/neurintsurg-2015-012101 Verlag Resolving-System Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_62 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_120 GBV_ILN_121 GBV_ILN_150 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_374 GBV_ILN_602 GBV_ILN_647 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2057 GBV_ILN_2064 GBV_ILN_2093 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2119 GBV_ILN_2129 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2472 GBV_ILN_2522 GBV_ILN_2893 GBV_ILN_2992 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4277 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4336 GBV_ILN_4346 GBV_ILN_4367 GBV_ILN_4393 GBV_ILN_4753 AR 8 2016 11 1116-1118 4 2013 01 DE-16-250 2986427731 00 --%%-- --%%-- --%%-- --%%-- l01 06-11-17 2013 01 DE-16-250 00 s hd2016 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_5 2013 01 DE-16-250 03 s s_4 2013 01 DE-16-250 04 p (DE-627)149617481X Seker, Fatih 2013 01 DE-16-250 04 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1565063945 Potreck, Arne 2013 01 DE-16-250 05 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 2013 01 DE-16-250 06 p (DE-627)1501228323 Möhlenbruch, Markus Alfred 2013 01 DE-16-250 06 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 06 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 06 s pos_3 2013 01 DE-16-250 07 p (DE-627)1450183360 Bendszus, Martin 2013 01 DE-16-250 07 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 07 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 07 s pos_4 2013 01 DE-16-250 08 p (DE-627)147292407X Pham, Mirko 2013 01 DE-16-250 08 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 08 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 08 s pos_5

Currently, there is no gold standard for collateral assessment by CT angiography (CTA). This study compared four frequently used collateral scores with regard to their correlation with early infarct core and mismatch ratio. Methods: 30 consecutive patients with acute occlusion of the M1 segment or terminal carotid artery were reviewed retrospectively. Collaterals were assessed using dynamic and also single-phase CTA according to grading systems by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR), Alberta Stroke Program Early CT Score (ASPECTS) (on collaterals), Christoforidis et al and Miteff et al. The Christoforidis and ASITN/SIR scores, which were initially designed for conventional angiography, were adapted to be applicable to CTA. The scores were compared with respect to early infarct core and mismatch ratio in perfusion CT estimated by RAPID software using Spearman correlation. Results: ASITN/SIR and ASPECTS collateral scores showed good correlation with early infarct core (rho=-0.696, p<0.001 and rho=-0.677, p<0.001) and mismatch ratio (rho=0.609, p<0.001 and rho=0.581, p<0.001). In contrast, the Christoforidis and Miteff scores correlated less well with infarct core (rho=0.245, p=0.191 and rho=-0.272, p=0.145, respectively) and mismatch ratio (rho=-0.329, p=0.075 and rho=0.279, p=0.135, respectively). ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion. 2015 Potreck, Arne verfasserin (DE-588)1031679790 (DE-627)737108886 (DE-576)379370638 aut Möhlenbruch, Markus Alfred 1979- verfasserin (DE-588)137693591 (DE-627)594845041 (DE-576)304845655 aut Bendszus, Martin verfasserin (DE-588)1032676426 (DE-627)738634131 (DE-576)175567697 aut Pham, Mirko 1978- verfasserin (DE-588)132435241 (DE-627)522697763 (DE-576)252667034 aut Enthalten in Journal of neuroInterventional surgery London : BMJ Journals, 2009 8(2016), 11, Seite 1116-1118 Online-Ressource (DE-627)605217548 (DE-600)2506028-4 (DE-576)308906721 1759-8486 nnns volume:8 year:2016 number:11 pages:1116-1118 extent:4 http://dx.doi.org/10.1136/neurintsurg-2015-012101 Verlag Resolving-System Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_62 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_120 GBV_ILN_121 GBV_ILN_150 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_374 GBV_ILN_602 GBV_ILN_647 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2057 GBV_ILN_2064 GBV_ILN_2093 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2119 GBV_ILN_2129 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2472 GBV_ILN_2522 GBV_ILN_2893 GBV_ILN_2992 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4277 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4336 GBV_ILN_4346 GBV_ILN_4367 GBV_ILN_4393 GBV_ILN_4753 AR 8 2016 11 1116-1118 4 2013 01 DE-16-250 2986427731 00 --%%-- --%%-- --%%-- --%%-- l01 06-11-17 2013 01 DE-16-250 00 s hd2016 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_5 2013 01 DE-16-250 03 s s_4 2013 01 DE-16-250 04 p (DE-627)149617481X Seker, Fatih 2013 01 DE-16-250 04 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1565063945 Potreck, Arne 2013 01 DE-16-250 05 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 2013 01 DE-16-250 06 p (DE-627)1501228323 Möhlenbruch, Markus Alfred 2013 01 DE-16-250 06 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 06 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 06 s pos_3 2013 01 DE-16-250 07 p (DE-627)1450183360 Bendszus, Martin 2013 01 DE-16-250 07 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 07 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 07 s pos_4 2013 01 DE-16-250 08 p (DE-627)147292407X Pham, Mirko 2013 01 DE-16-250 08 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 08 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 08 s pos_5

This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion. 2015 Potreck, Arne verfasserin (DE-588)1031679790 (DE-627)737108886 (DE-576)379370638 aut Möhlenbruch, Markus Alfred 1979- verfasserin (DE-588)137693591 (DE-627)594845041 (DE-576)304845655 aut Bendszus, Martin verfasserin (DE-588)1032676426 (DE-627)738634131 (DE-576)175567697 aut Pham, Mirko 1978- verfasserin (DE-588)132435241 (DE-627)522697763 (DE-576)252667034 aut Enthalten in Journal of neuroInterventional surgery London : BMJ Journals, 2009 8(2016), 11, Seite 1116-1118 Online-Ressource (DE-627)605217548 (DE-600)2506028-4 (DE-576)308906721 1759-8486 nnns volume:8 year:2016 number:11 pages:1116-1118 extent:4 http://dx.doi.org/10.1136/neurintsurg-2015-012101 Verlag Resolving-System Volltext GBV_USEFLAG_U GBV_ILN_2013 ISIL_DE-16-250 SYSFLAG_1 GBV_KXP GBV_ILN_11 GBV_ILN_20 GBV_ILN_22 GBV_ILN_23 GBV_ILN_24 GBV_ILN_31 GBV_ILN_32 GBV_ILN_39 GBV_ILN_40 GBV_ILN_62 GBV_ILN_65 GBV_ILN_69 GBV_ILN_70 GBV_ILN_73 GBV_ILN_74 GBV_ILN_100 GBV_ILN_101 GBV_ILN_105 GBV_ILN_120 GBV_ILN_121 GBV_ILN_150 GBV_ILN_161 GBV_ILN_170 GBV_ILN_171 GBV_ILN_187 GBV_ILN_206 GBV_ILN_213 GBV_ILN_230 GBV_ILN_285 GBV_ILN_293 GBV_ILN_370 GBV_ILN_374 GBV_ILN_602 GBV_ILN_647 GBV_ILN_702 GBV_ILN_2001 GBV_ILN_2003 GBV_ILN_2005 GBV_ILN_2006 GBV_ILN_2007 GBV_ILN_2008 GBV_ILN_2009 GBV_ILN_2010 GBV_ILN_2011 GBV_ILN_2014 GBV_ILN_2015 GBV_ILN_2018 GBV_ILN_2020 GBV_ILN_2021 GBV_ILN_2025 GBV_ILN_2026 GBV_ILN_2031 GBV_ILN_2034 GBV_ILN_2037 GBV_ILN_2038 GBV_ILN_2044 GBV_ILN_2049 GBV_ILN_2050 GBV_ILN_2056 GBV_ILN_2057 GBV_ILN_2064 GBV_ILN_2093 GBV_ILN_2108 GBV_ILN_2110 GBV_ILN_2111 GBV_ILN_2113 GBV_ILN_2116 GBV_ILN_2119 GBV_ILN_2129 GBV_ILN_2147 GBV_ILN_2148 GBV_ILN_2153 GBV_ILN_2190 GBV_ILN_2336 GBV_ILN_2446 GBV_ILN_2472 GBV_ILN_2522 GBV_ILN_2893 GBV_ILN_2992 GBV_ILN_4012 GBV_ILN_4035 GBV_ILN_4037 GBV_ILN_4046 GBV_ILN_4112 GBV_ILN_4125 GBV_ILN_4126 GBV_ILN_4242 GBV_ILN_4246 GBV_ILN_4249 GBV_ILN_4251 GBV_ILN_4277 GBV_ILN_4305 GBV_ILN_4306 GBV_ILN_4307 GBV_ILN_4313 GBV_ILN_4322 GBV_ILN_4323 GBV_ILN_4324 GBV_ILN_4326 GBV_ILN_4328 GBV_ILN_4333 GBV_ILN_4336 GBV_ILN_4346 GBV_ILN_4367 GBV_ILN_4393 GBV_ILN_4753 AR 8 2016 11 1116-1118 4 2013 01 DE-16-250 2986427731 00 --%%-- --%%-- --%%-- --%%-- l01 06-11-17 2013 01 DE-16-250 00 s hd2016 2013 01 DE-16-250 01 s (DE-627)1410508463 wissenschaftlicher Artikel (Zeitschrift) 2013 01 DE-16-250 02 s per_5 2013 01 DE-16-250 03 s s_4 2013 01 DE-16-250 04 p (DE-627)149617481X Seker, Fatih 2013 01 DE-16-250 04 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 04 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 04 s pos_1 2013 01 DE-16-250 05 p (DE-627)1565063945 Potreck, Arne 2013 01 DE-16-250 05 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 05 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 05 s pos_2 2013 01 DE-16-250 06 p (DE-627)1501228323 Möhlenbruch, Markus Alfred 2013 01 DE-16-250 06 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 06 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 06 s pos_3 2013 01 DE-16-250 07 p (DE-627)1450183360 Bendszus, Martin 2013 01 DE-16-250 07 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 07 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 07 s pos_4 2013 01 DE-16-250 08 p (DE-627)147292407X Pham, Mirko 2013 01 DE-16-250 08 k (DE-627)1416741267 Neurologische Universitätsklinik 2013 01 DE-16-250 08 s (DE-627)1410501914 Verfasser 2013 01 DE-16-250 08 s pos_5

Currently, there is no gold standard for collateral assessment by CT angiography (CTA). This study compared four frequently used collateral scores with regard to their correlation with early infarct core and mismatch ratio. Methods: 30 consecutive patients with acute occlusion of the M1 segment or terminal carotid artery were reviewed retrospectively. Collaterals were assessed using dynamic and also single-phase CTA according to grading systems by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR), Alberta Stroke Program Early CT Score (ASPECTS) (on collaterals), Christoforidis et al and Miteff et al. The Christoforidis and ASITN/SIR scores, which were initially designed for conventional angiography, were adapted to be applicable to CTA. The scores were compared with respect to early infarct core and mismatch ratio in perfusion CT estimated by RAPID software using Spearman correlation. Results: ASITN/SIR and ASPECTS collateral scores showed good correlation with early infarct core (rho=-0.696, p<0.001 and rho=-0.677, p<0.001) and mismatch ratio (rho=0.609, p<0.001 and rho=0.581, p<0.001). In contrast, the Christoforidis and Miteff scores correlated less well with infarct core (rho=0.245, p=0.191 and rho=-0.272, p=0.145, respectively) and mismatch ratio (rho=-0.329, p=0.075 and rho=0.279, p=0.135, respectively). ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion.</subfield></datafield><datafield tag="534" ind1=" " ind2=" "><subfield code="c">2015</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Potreck,

title_auth	Comparison of four different collateral scores in acute ischemic stroke by CT angiography
abstract	Purpose: Multiple scores have been described for the assessment of collateralization in acute ischemic stroke. Currently, there is no gold standard for collateral assessment by CT angiography (CTA). This study compared four frequently used collateral scores with regard to their correlation with early infarct core and mismatch ratio. Methods: 30 consecutive patients with acute occlusion of the M1 segment or terminal carotid artery were reviewed retrospectively. Collaterals were assessed using dynamic and also single-phase CTA according to grading systems by the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR), Alberta Stroke Program Early CT Score (ASPECTS) (on collaterals), Christoforidis et al and Miteff et al. The Christoforidis and ASITN/SIR scores, which were initially designed for conventional angiography, were adapted to be applicable to CTA. The scores were compared with respect to early infarct core and mismatch ratio in perfusion CT estimated by RAPID software using Spearman correlation. Results: ASITN/SIR and ASPECTS collateral scores showed good correlation with early infarct core (rho=-0.696, p<0.001 and rho=-0.677, p<0.001) and mismatch ratio (rho=0.609, p<0.001 and rho=0.581, p<0.001). In contrast, the Christoforidis and Miteff scores correlated less well with infarct core (rho=0.245, p=0.191 and rho=-0.272, p=0.145, respectively) and mismatch ratio (rho=-0.329, p=0.075 and rho=0.279, p=0.135, respectively). ASPECTS and ASITN/SIR showed excellent cross-correlation (rho=0.901, p<0.001). Conclusions: Compared with the Christoforidis and Miteff scores, the modified ASITN/SIR and ASPECTS collateral scores showed consistently higher correlation with the extent of early infarct core and mismatch volume. This is probably because these scores evaluate the extent and delay of vascular enhancement in the affected territory rather than the backflow of contrast medium to the occlusion.
