Background: Aneurysms at the origin of the posterior communicating artery (PcommA) have been demonstrated to be effectively treated with the pipeline embolization device (PED). Much less is known about the efficacy of the PED for aneurysms associated with a fetal posterior cerebral artery (fPCA) variant.
Objective: To study PED treatment efficacy of PcommA aneurysms, including fPCA aneurysms.
Objective: Carotid cavernous fistula (CCF) development after Pipeline Embolization Device (PED) treatment of cavernous carotid aneurysms (CCA) can be a challenging pathology to treat for the neurointerventionalist.
Methods: A database of all patients whose aneurysms were treated with the PED since its approval by the Food and Drug Administration in 2011 was retrospectively reviewed. Demographic information, aneurysm characteristics, treatment technique, antiplatelet regimen, and follow-up data were collected.
Background: Epsilon aminocaproic acid (EACA) has been used in the past to prevent cerebral aneurysm rerupture. Recent studies have indicated that short-term treatment with EACA can lower rebleeding rates without significantly increasing ischemic or thrombotic complications or permanent shunt rates. The goal of this study is to determine the efficacy of EACA in the prevention of aneurysm rerupture at a high volume subarachnoid hemorrhage center.

Methods: A 47-year-old female patient initially presented with a subarachnoid hemorrhage and an anterior communicating artery aneurysm.
Introduction: Endovascular coil embolization has an established role alongside microsurgical clipping in the treatment of aneurysms. We studied previously clipped aneurysms that presented as subarachnoid hemorrhage and were treated by coil embolization.
Methods: A retrospective review was performed of two prospectively maintained databases from two institutions (Cleveland Clinic, Emory University) that spanned 12 years.

Objective: The aim of the study is to determine the efficacy of indocyanine green (ICG) videoangiography for confirmation of vascular anastomosis patency in both extracranial-intracranial and intracranial-intracranial bypasses.
Methods: Intraoperative ICG videoangiography was used as a surgical adjunct for 56 bypasses in 47 patients to assay the patency of intracranial vascular anastomosis. These patients underwent a bypass for cerebral ischemia in 31 instances and as an adjunct to intracranial aneurysm surgery in 25.
Background And Importance: Aneurysms of the posterior circulation may manifest with neurological deficits related to mass effect on the brainstem. We present an unusual case of an aneurysm resulting in selective lower-extremity weakness and gait instability.
Clinical Presentation: A 61-year-old man presents with progressively worsening gait instability over the course of several months.
Background: Intraprocedural rupture is a dangerous complication of endovascular treatment. Small ruptured anterior communicating artery (ACoA) aneurysms and microaneurysms present a challenge for both surgical and endovascular therapies to achieve obliteration. An understanding of the complication rates of treating ruptured ACoA microaneurysms may help guide therapeutic options.

Methods: Intraoperative ICG videoangiography was used as a surgical adjunct in 25 patients with cranial and spinal dural arteriovenous fistulae to identify the fistula and verify its complete obliteration. The findings on ICG videoangiography were compared with intraoperative and/or postoperative imaging.
