Abstract
Background and purpose The treatment of complex intracranial aneurysms can be challenging with stand-alone open or endovascular techniques, particularly after rupture. A combined open and endovascular strategy can potentially limit the risk of extensive dissections with open-only techniques, and allow for aggressive definitive endovascular treatments with minimized downstream ischemic risk. Materials and methods Retrospective, single-institution review of consecutive patients undergoing combined open revascularization and endovascular embolization/occlusion for complex intracranial aneurysms from 1/2016 to 6/2022. Results Ten patients (4 male [40%]; mean age 51.9 ± 8.7 years) underwent combined open revascularization and endovascular treatment of intracranial aneurysms. The majority of aneurysms, 9/10 (90%), were ruptured and 8/10 (80%) were fusiform in morphology. Aneurysms of the posterior circulation represented 8/10 (80%) of the cases (vertebral artery [VA] involving the posterior inferior cerebellar artery [PICA] origin, proximal PICA or anterior inferior cerebellar artery/PICA complex, or proximal posterior cerebral artery). Revascularization strategies included intracranial-to-intracranial (IC-IC; 7/10 [70%]) and extracranial-to-intracranial (EC-IC; 3/10 [30%]) constructs, with 100% postoperative patency. Initial endovascular procedures (consisting of aneurysm/vessel sacrifice in 9/10 patients) were performed early after surgery (0.7 ± 1.5 days). In one patient, secondary endovascular vessel sacrifice was performed after an initial sub-occlusive embolization. Treatment related strokes were diagnosed in 3/10 patients (30%), largely from involved or nearby perforators. All bypasses with follow-up were patent (median 14.0, range 4-72 months). Good outcomes (defined as a Glasgow Outcomes Scale ≥4 and modified Rankin Scale ≤2) occurred in 6/10 patients (60%). Conclusion A variety of complex aneurysms not amenable to stand-alone open or endovascular techniques can be successfully treated with combined open and endovascular approaches. Recognition and preservation of perforators is critical to treatment success.

Liu P, Li Z, Hu L, Liu Y, Li P, Zhu W, Tian Y, Mao Y. Clinical characteristics, endovascular choices, and surgical outcomes of intracranial vertebral artery dissecting aneurysms: a consecutive series of 196 patients. J Neurosurg 2023; 138:215-222. [PMID: 35901773 DOI: 10.3171/2022.4.jns22609] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 04/07/2022] [Indexed: 01/04/2023]
Abstract
OBJECTIVE The authors aimed to evaluate the clinical features, endovascular strategy selection, and outcomes of vertebral artery (VA) dissecting aneurysms (VADAs) near the origin of the posterior inferior cerebellar artery (PICA). METHODS Clinical data were obtained from 196 patients with 202 VADAs who had been surgically treated at the authors' hospital between 2005 and 2021. The patients' medical records, imaging data, and follow-up outcomes were retrospectively analyzed. RESULTS All 196 patients (148 male, 48 female; mean age 53 years) underwent endovascular therapy for VADA. The most common chief complaints were headache (56.6%), dizziness (40.8%), and other occasional symptoms (18.4%). Twenty-six patients experienced posterior circulation ischemia, and 25 patients experienced subarachnoid hemorrhage (SAH). On DSA images, 37 aneurysms were found in the dominant VA, and 165 aneurysms were found on the nondominant side. Eighty-eight VADAs had stenosis. Regarding the VADA location, there were 59 distal, 51 proximal, 23 ventral, 64 PICA, and 5 obliteration types. Single-stent implantation (10.9%), overlapping stent implantation (23.8%), flow diverter (FD) implantation (11.9%), single stent-assisted coil (SAC) embolization (31.7%), overlapping SAC embolization (12.9%), parent artery occlusion (PAO) (8.4%), and FD-assisted coil embolization (0.5%) were chosen. The follow-up rate was 82.7%. The modified Rankin Scale (mRS) score was 0.5 ± 1.1. Ninety-six patients underwent DSA. The complete occlusion rates were 100%, 81.4%, 56.7%, and 76.5% in the PAO group, SAC reconstruction group, stent implantation group, and FD implantation group, respectively. CONCLUSIONS Young patients showed a higher probability of SAH, and elderly patients showed a higher probability of posterior circulation infarction. The surgical plan selection should be based on the SAH history, VA dominant side, and PICA origin location.
