Abstract:
Objective:To investigate the feasibility and safety of endovascular recanalization for symptomatic non-acute intracranial arterial occlusion (NAICO).Methods:Twenty-five consecutive patients who underwent endovascular recanalization for NAICO between January 2017 and October 2019 at Department of Neurosurgery, Beijing Hospital were retrospectively reviewed.There were 20 males and 5 females, aged (60.5±11.0) years (range: 41 to 73 years).The preoperative modified Rankin score( M( Q R)) was 2 (2.5)(range: 1 to 5).The occlusion time was 40 (54)days (range: 17 to 570 days).The demographic data were collected. The initial procedural results, including the rate of successful recanalization, periprocedural complications and data pertaining to angiographic and clinical follow-up were recorded. Results:Recanalization was successful in 20 of 27 occlusive lesions of 25 patients. Intraoperative complications occurred in 3 cases, including vascular perforation in 1 case, arterial dissection in 1 case, and perforator occlusion occurred in 1 case. The incidence of permanent complications was 3.7% (1/27). All 25 patients underwent clinical follow-up, with a median period of 8 months (range: 1 to 33 months), and 23 patients with improved or stable modified Rankin scale. One patient developed new ischemic symptoms 2 months after discharge, and 1 patient died of complications of bed rest.The results of the angiography follow-up (median 4 months, range: 2 days to 9 months) showed that reocclusion occurred in 5 of all 20 successfully recanalized patients.Conclusions:Endovascular recanalization for symptomatic NAICO is feasible, relatively safe, and efficacious in highly selected cases. However, further larger scale pilot studies are needed to determine the efficacy and long-term outcome associated with this treatment.
