摘要

Background: Endovascular aneurysm coiling is a minimally invasive method to manage intracranial aneurysms. However, aneurysm coiling may fail in very small aneurysms (VSAs); thus, flow diverter (FD) is recommended as an alternative in these difficult aneurysms. Herein, we report our experience and outcomes of FD to treat VSA of the internal carotid artery (ICA). Methods: Over a 3-year period, a total of 70 patients with 87 unruptured VSAs of the ICA were managed by FD. There were 54 men and 16 women, with a mean age of 57 (range, 41-75) years. We retrospectively assessed the clinical data, aneurysm characteristics, and angiographic as well as clinical outcomes of patients treated by FD and compared with larger aneurysms. Results: Fifty aneurysms (58%) were located in the supraclinoid ICA, followed by paraclinoid ICA (n = 31, 36%) and cavernous ICA (n = 6, 7%). Most aneurysms (n = 72, 83%) were between 2 and 3 mm in size. The mean aneurysm size was 2.3 mm (range, 1.5-3 mm). Follow-up angiographic data (mean, 13 months) were available in 54 patients with 68 aneurysms. Successful FD deployment in an ideal position to bride aneurysm was achieved in 86 of 87 aneurysms (99%). Complete obliteration (CO) was achieved in 63 aneurysms (93%). Compared with larger aneurysms (>3 mm), VSAs had the tendency to achieve CO (p < 0.05) in a midterm follow-up. Two patients (2.8%) had intraprocedural complications, including in-stent thrombosis (n = 1) and distal embolism (n = 1). One patient (1.4%) suffered from mild limb weakness. Conclusion: The use of FD to manage VSA was technically feasible, and the procedure was simpler than those of larger aneurysms. FD stenting of VSAs was confirmed to be effective and safe and had higher CO rate than those in larger aneurysms in a midterm angiographic follow-up.
