Hybrid operation to revascularize long-segment occluded internal carotid artery prevent further ischemic events

Purpose The effects and complications of hybrid procedure (combined carotid endarterectomy and carotid stenting) to revascularize chronic long-segment occlusion of internal carotid artery (ICA) are currently unknown and the purpose of this study. Methods Sixty-five patients with long-segment occlusi...

description Purpose The effects and complications of hybrid procedure (combined carotid endarterectomy and carotid stenting) to revascularize chronic long-segment occlusion of internal carotid artery (ICA) are currently unknown and the purpose of this study. Methods Sixty-five patients with long-segment occlusion of ICA were prospectively enrolled and divided into two groups of revascularization with hybrid operation ( n  = 30) and medication group ( n  = 35), and clinical and angiographic data were analyzed. Results The duration from symptom onset to revascularization ranged 17–120 days (mean 40.5 ± 5.0) in the hybrid operation, with a success revascularization rate of 100%. All patients had thrombi extracted with the clot length ranging 5–8 cm (mean 6.3 ± 0.9). The thrombolysis in cerebral infarction grade (TICI) was significantly ( P
