Thrombus removal by solitaire stent for acute occlusion of carotid artery and middle cerebral artery

Abstract

Objective To investigate the clinical effect of thrombus removal by solitaire stent for patients with acute occlusion of internal carotid artery and middle cerebral artery. Methods The clinical data of 89 patients with acute occlusion of internal carotid artery and middle cerebral artery treated in our hospital from Feb., 2016 to Feb., 2018 were retrospectively analyzed. The patients were divided into a control group (n=35) and an observation group (n=54). The control group were treated with ateptidase, and the observation group with ateptidase and thrombus removal by solitaire stent. The neurologic function, prognosis, and thrombus extraction were compared between the two groups. Results The NIHSS scores 7 and 14 d after the treatment in the observation group were (8.81±1.69) and (5.21±0.85), which were lower than those in the control group (all P 0.05). In the observation group, 52 patients underwent thrombus removal once, 1 patient 2 times, 1 patient 3 times, and no more than 3 times. The mean time of thrombectomy was (38.95 ±6.18) min. Conclusions On the basis of intravenous thrombolysis, thrombus removal by solitaire stent for patients with acute occlusion of internal carotid artery and middle cerebral artery can effectively relieve their neurological deficit and has no adverse effects on their prognosis.
