Abstract:
Objective:To evaluate the feasibility, safety and efficacy of the treatment of chronic symptomatic internal carotid artery long-segmental occlusion.
Methods:Fifty-one cases of chronic symptomatic internal carotid artery long-segmental occlusion (arterial occlusion more than 2 anatomical segments) who were treated with hybrid surgery (plaque located at the carotid sinus) or endovascular revascularization (plaque located at the distal end of the internal carotid artery occlusion) from May 2015 to May 2018 were reviewed. Recanalization, perioperative complications, stroke events, and reocclusion events during the follow-up period were recorded.
Results:The occlusion was recanalized successfully in 45 of 51 patients (88.2%, 45/51), 6 patients failed because the guidewire could not cross the distal arterial occlusion. And the technical success rate was 96.0% (24/25) in hybrid surgery and 80.8% (21/26) in endovascular revascularization. Perioperative complications occurred in 2 patients who underwent combined endovascular treatment. One patient had a small branch embolism due to intraoperative thrombus shift, and 1 patient had large area cerebral infarction. The complications occurred in 2 patients who underwent thybrid surgery, including 1 case of internal carotid cavernous fistula and 1 case of acute reocclusion of internal carotid artery. Forty-four patients with successful operation received clinical follow-up, with the median follow-up time of 24 months (7-43 months). No recurrent stroke and death occurred during the follow-up period. Clinical symptoms were improved in 34 cases. Totally 44 patients received imaging follow-up, and during the median imaging follow-up time of 8 month (4-28 months), 6 cases had reocclusion, and 2 cases had restenosis.
Conclusion:The treatment of chronic symptomatic internal carotid artery long-segmental occlusion is technically feasible and safety with good short-term efficacy. However, its exact efficacy remains to be confirmed by long-term follow-up studies with large samples.
