Woven Endobridge device for treatment of dissection-related PICA aneurysm. Interv Neuroradiol. 2021;27(3):388-390. doi:10.1177/1591019920968349https://hdl.handle.net/1805/34203Ruptured vertebrobasilar dissecting aneurysms require urgent, often challenging treatment as they have with a high re-hemorrhage rate within the first 24 hours. The patient is a 57-year-old woman who presented with severe-sudden onset headache. Further work up showed a ruptured dissecting aneurysm of the caudal loop of the posterior inferior cerebellar artery (PICA) with associated narrowing distally, in the ascending limb. The aneurysm was immediately occluded with a Woven Endobridge (WEB) device (MicroVention, Tustin, CA, USA) while flow diversion treatment of the diseased ascending limb was postponed. Follow-up angiography three months later showed complete occlusion of the aneurysm, as well as healing of the diseased distal vessel, obviating the need for further intervention. WEB embolization of a ruptured dissecting posterior circulation aneurysm provided an excellent outcome for this patient.en-USPublisher PolicyPICA aneurysmPosterior inferior cerebellar arteryWoven EndobridgeWEB deviceAneurysmDissectionArticle
