Endovascular repair with covered stent for the treatment of ruptured carotid artery pseudoaneurysms / 介入放射学杂志

ABSTRACT

Objective To evaluate the efficacy and safety of endovascular repair with covered stent in treating ruptured carotid artery pseudoaneurysms.Methods The clinical data of 15 patients with ruptured carotid artery pseudoaneurysm,who were admitted to Sun Yat-Sen Memorial Hospital of Zhongshan University during the period from July 2009 to July 2015 to receive emergency rescue with endovascular covered stent implantation,were retrospectively analyzed.Of the 15 patients,the rupture of common carotid artery pseudoaneurysm caused by direct trauma was seen in one and caused by cervical operation was observed in one,the rupture of internal carotid artery pseudoaneurysm caused by cervical operation was found in 3,and the rupture of internal carotid artery pseudoaneurysm due to radiotherapy for nasopharyngeal carcinoma was seen in 10.Results Successful rescue with endovascular repair using covered stent implantation was obtained in all 15 patients.No immediate procedure-related complications or death occurred.The mean follow-up time was 11 months.During the follow-up period,no re-bleeding or cerebral ischemic complications occurred.Conclusion For the treatment of ruptured carotid artery pseudoaneurysms,endovascular repair with covered stent is minimally invasive,safe and effective with less complications;and along with the occlusion of carotid artery rupture,the blood supply of the head and neck returns to normal.However,further clinical researches with larger samples are needed before its long-term efficacy can be completely clarified.
