Abstract
Objectives Optimal treatment strategies for traumatic internal carotid artery (ICA) pseudoaneurysms are controversial. The low-profile visualized intraluminal support (LVIS) device is a braided stent with a metal coverage rate between traditional laser cut stents and flow diversion devices. We report here our therapy strategy using the LVIS stent-assisted coiling for treatment of traumatic ICA pseudoaneurysms.Methods Patients with traumatic ICA pseudoaneurysms treated by the LVIS stent-assisted coiling in our center between January 2015 to June 2021 were reviewed. The complications, radiographic, and clinical outcomes of these patients were analyzed.Results A total of 12 pseudoaneurysms in 12 patients were included. Immediate postoperative angiogram showed that six (50%) aneurysms were Raymond grade 1, four (33.3%) were grade 2, and two (16.7%) were grade 3. Two patients with severe primary cranial injury discontinued treatment after the procedure. During the follow-up of the other ten patients, two patients (20%) received additional coiling because of recanalization of the pseudoaneurysm. At the last angiographic follow-up examination, all aneurysms were Raymond grade 1. Postoperative multiple cerebral infarction occurred in two patients. Of the ten patients with a mean clinical follow-up of 32.2 ± 27.9 (median, 18) months, eight patients recovered well, one patient had right hemiplegia, and one patient died of airway damage, which was unrelated to the pseudoaneurysm.Conclusions LVIS stent-assisted coiling was a feasible approach for the treatment of traumatic ICA pseudoaneurysms.
