Giant Fusiform Vertebral Artery Aneurysm Treated with Microsurgical Bypass and Endovascular Coiling after Failed Flow Diversion: A Case Report and Discussion
نویسندگان
چکیده
Giant vertebral and vertebrobasilar (VB) aneurysms constitute a rare form of intracranial aneurysms that exhibit a dismal natural history associated with significant morbidity and mortality.1 Current endovascular treatments include coil embolization as well as the more recent use of flow-diverting stents, each having known risks of aneurysm recurrence, ischemia, and death.2 Extracranial–intracranial (EC–IC) bypasses have been used to grant adequate perfusion for parent vessel deconstruction or flow reversal. We present a case of a giant partially thrombosed fusiform aneurysm of the distal left vertebral artery treated with a flow-diverting stent and rescued, after its failure, with microsurgical bypass and coil embolization.

Persistent Aneurysm Growth Following Pipeline Embolization Device Assisted Coiling of a Fusiform Vertebral Artery Aneurysm: A Word of Caution!
The complex morphology of vertebrobasilar fusiform aneurysms makes them one of the most challenging lesions treated by neurointerventionists. Different management strategies in the past included parent vessel occlusion with or without extra-intracranial bypass surgery and endovascular reconstruction by conventional stents. Use of flow diversion has emerged as a promising alternative option with...
متن کاملSuccessful endovascular coiling of a ruptured internal iliac artery aneurysm: a case report
Ruptured internal iliac artery aneurysms (IIAA) are extremely rare, and the repair can be challenging. This case reports described an 83-year-old patient who presented at our Emergency Department with acute abdominal pain based on a ruptured IIAA. He refused open repair and only wanted to be treated as minimally invasive as possible. Therefore endovascular embolization of the IIAA was performed...

Treatment of giant posterior circulation aneurysms, via endovascular or microsurgical approaches, carries a high risk of morbidity and mortality. While flow-diverting stents (FDSs) represent a potent therapy for endovascular reconstruction of complex aneurysms, they are also associated with novel complications for which effective salvage techniques are lacking. We present a unique complication ...
متن کاملRadical surgical treatment for recurrent giant fusiform thrombosed vertebral artery aneurysm previously coiled
BACKGROUND Fusiform aneurysms are rare (<1%) and the underlying pathophysiology is not well known. Endovascular coiling is the standard of treatment; however, a surgical procedure with vascular reconstruction by excluding the pathological segment of the vessel and restoring the blood flow, seems to be the most effective and definitive treatment. CASE DESCRIPTION We report a patient who presen...
متن کاملFusiform Aneurysm on the Basilar Artery Trunk Treated with Intra-Aneurysmal Embolization with Parent Vessel Occlusion after Complete Preoperative Occlusion Test
Fusiform aneurysms on the basilar artery (BA) trunk are rare. The microsurgical management of these aneurysms is difficult because of their deep location, dense collection of vital cranial nerves, and perforating arteries to the brain stem. Endovascular treatment is relatively easier and safer compared with microsurgical treatment. Selective occlusion of the aneurysmal sac with preservation of ...
