The management of cerebrovascular disease has advanced considerably in 2015. Five randomized control trials have firmly established the role of endovascular thrombectomy for ischemic strokes due to large vessel occlusion. The randomized trial of intraarterial treatment for acute ischemic stroke (MR CLEAN) (Berkhemer et al. NEJM 2015;372:11-20) was the first of a series on the topic. There was a total of 5 randomized controlled trials published showing benefit in terms of functional outcomes at 90days for mechanical thrombectomy including the Endovascular Therapy for Ischemic stroke with perfusion-imaging selection (EXTEND IA) (Campbell et al. NEJM 2015;372:1009-18), the Randomized assessment of rapid endovascular treatment of ischemic stroke (ESCAPE) (Goyal et al. NEJM 2015;372:1019-30) trials, the stent-retriever thrombectomy after IV t-PA is t-PA alone in stroke (SWIFT-PRIME) (Saver et al. NEJM 2015;372:2285-95), and the thrombectomy within 8h after symptom onset in Ischemic stroke (REVASCAT) trial (Jovin et al. NEJM 2015; 372:2296-306). Six-year results from randomized controlled Barrow Ruptured Aneurysm Trial (BRAT) found no significant difference in functional outcomes in patients ruptured aneurysms treated surgically clippings versus endovascular treatment (Spetzler et al. JNS 2015;123:609-17. The 10-year results of the International Subarachnoid Aneurysm trial (ISAT) reported similar mortality rates and good functional outcomes between clipped and coiled patients (Molyneux et al. Lancet 2015;385:691-7). We also discuss the impact of genome wide sequencing studies in familial aneurysms, the largest publication on stent assisted coiling and flow diverter for aneurysms and noteworthy papers relevant to Moyamoya and cavernous malformations (Yang et al. Neurosurgery 2015;77:241-7).
