Nguyen, t.N., roy, d., guilbert, f., raymond, j., <(>&<)> weill, a.(2008).Endovascular trapping of a vertebral artery segment to control pica origin tearing.Journal of neuroimaging, 18(4), 418¿421.Doi: 10.1111/j.1552-6569.2007.00195.X medtronic literature review found a report of patient complications in association with hyperglide balloon and rebar microcatheter.The purpose of this article was to describe a technique of isolating the subarachnoid segment of the vertebral artery using two balloons to trap flow to a ruptured posterior inferior cerebellar artery (pica) aneurysm allowing time to coil the parent artery with the aneurysm.The article does not state any technical issues during use of the hyperglide or rebar.The following intra- or post-procedural outcomes were noted: during placement of the first coil, aneurysm perforation was noted.Despite conventional measures to manage the perforation (anticoagulation reversal, balloon inflation, placement of a second coil, and ventricular drain), contrast extravasation persisted after 45 minutes.A second balloon was positioned via the right vertebral artery at the right vertebrobasilar junction and inflated.The first balloon was pulled back, inflated, allowing trapping of the ruptured site.The aneurysm and adjacent vertebral segment were rapidly coiled to occlude the ruptured site under local flow arrest.The patient awoke with dysarthria, persistent 4/5 left hemiparesis, left hypoesthesia, and dysphagia.A head ct revealed higher density of subarachnoid hemorrhage in the basal cisterns diffusely, and no increase in ventricular size.The patient was discharged to rehabilitation 2 weeks after hospitalization, with improvement of her neurological status.At follow-up, mri obtained 2 months later revealed punctate ischemia in the left cerebellum and left medulla.At 6-month clinical follow-up, the patient had good recovery of the left hemiparesis, with a modified rankin scale of 1.They continued with left sided hemisensory loss and mild gait ataxia.
