Balloon Assisted Coiling of a Ruptured Posterior Communicating Artery Infundibular Aneurysm: Case Report and Review of the Literature.

Herein, we present the case of a 55-year-old female who presented with subarachnoid hemorrhage (SAH) due to rupture of a posterior communicating artery infundibular aneurysm. The patient was treated during the acute phase of SAH via balloon-assisted coil embolization. The patient recovered without any neurologic sequalae. There is a dearth of literature describing the use of an endovascular approach for the treatment of ruptured intracranial infundibula or infundibular aneurysms. We propose the use of balloon assisted coil embolization as a viable therapeutic option for the treatment of ruptured intracranial infundibular aneurysms and present a detailed review of the literature.
