Abstract
OBJECTIVES: This study sought to evaluate the safety and efficacy of endovascular treatment of middle cerebral artery dissecting aneurysms(MCADAs).
METHOD: Fourteen patients with MCADAs received endovascular treatment between July 2009 and April 2016. MCADAs were identified by virtue of their unique radiographic features on cerebral angiography. Baseline characteristics, angiographic features, angiographic and clinical outcomes were analyzed retrospectively.
RESULTS: All fourteen MCADAs (including 6 ruptured and 8 unruptured) were successfully treated with the endovascular approach. Stent-assisted coiling was deployed in 12, coil alone in 1 and parent vessel occlusion in 1. Angiographic follow-up data were available for all patients at 6 months after treatment. Ten of fourteen MCADAs were completely occluded, while four were improved (near occlusion). All parent arteries and covered perforators remain patent in the non-parent-vessel-occlusion group. No ischemic strokes or other complications were observed at one year clinical follow up.
CONCLUSIONS: Our data suggest that endovascular treatment of middle cerebral artery dissecting aneurysms appear to be safe and effective, choice of treatment method needs to be individualized. Larger studies are required to evaluate these promising results.
