Background: Aneurysmal subarachnoid hemorrhage (SAH) is the most common cause of nontraumatic SAH. Current guidelines generally recommend observation for unruptured intracranial aneurysms smaller than 7 mm, for those are considered at low risk for spontaneous rupture according to available scoring systems.

Objective: We observed a tendency for SAH in small intracranial aneurysms in patients who are methamphetamine users.

Catheter-directed digital subtraction angiography (DSA) is considered the standard for evaluation of superficial temporal to middle cerebral artery (STA-MCA) bypass patency. Few clinical investigations have been performed that evaluate the efficacy of computed tomographic angiography (CTA) in the assessment of extracranial-intracranial bypass. Using multi-detector row CTA, STA-MCA bypass patency was assessed in the initial postoperative period and several months afterward and compared with DSA.

Objective: Our goal was to assess the long-term anatomic and clinical outcomes in patients with giant middle cerebral artery (MCA) aneurysms treated by endovascular coil embolization alone or in combination with cerebral revascularization.

Methods: One hundred twenty-six patients with giant intracranial aneurysms were endovascularly treated at the University of California, Los Angeles, between 1990 and 2007. Of these, 9 patients had partially thrombosed MCA aneurysms with incorporated branches.

Background: Complex DAVFs involving both the clivus and cavernous sinus are rare, especially when associated with brainstem compression from a large varix. In this report, we describe the use of a covered stent in combination with a liquid embolic agent to cure a complex clival-cavernous DAVF.

Methods: A 46-year-old man presented with 6 months of dizziness, dysphagia, and progressive dysarthria.

Objective: Dural arteriovenous fistulae (DAVFs) rarely involve the clivus. This report examines the clinical presentation, angiographic findings, endovascular management, and outcome of clival DAVFs. Particular attention was given to safety and efficacy of transarterial embolization using liquid embolic agents.
