ABSTRACT
BACKGROUND:
Flow diversion is a viable alternative for treatment of wide-neck and fusiform aneurysms originating from the posterior inferior cerebellar artery (PICA), but coverage of the PICA and vertebral perforating arteries may be a concern. The aim of this study was to examine procedural, clinical, and angiographic outcomes of patients with PICA aneurysms treated with the Pipeline Embolization Device.METHODS:
Retrospective review was performed of PICA aneurysms treated with the Pipeline device at 3 neurovascular centers, including periprocedural complications and clinical and angiographic outcomes.RESULTS:
In 16 procedures, 14 PICA aneurysms were treated with the Pipeline device. These included 11 saccular aneurysms with a mean size of 7.4 mm (range, 2.0-11.1 mm) and 3 fusiform aneurysms with a mean diameter of 6.1 mm (range, 5.0-8.0 mm) and mean length of 10.3 mm (range, 6.0-15.0 mm). One patient developed a PICA territory infarct with mild leg weakness that resolved in <7 days. Overall complication rate was 7% (1/14) per patient and 6% (1/16) per procedure. Mean duration of clinical follow-up was 13.5 months (range, 3 weeks to 61.7 months), with all patients returning to baseline functional status. Complete or near-complete aneurysm occlusion was achieved in 58% (7/12) of cases with angiographic follow-up (mean, 15 months; range, 4-61 months). All covered PICAs remained patent.CONCLUSIONS:
Flow diversion of PICA aneurysms is a safe and viable treatment option when traditional endovascular options are unlikely to preserve parent vessel patency.Palavras-chave
