Surgical management of cerebrovascular disorders is coordinated through the UCSF Center for Stroke and Cerebrovascular Disease, a multidisciplinary program at the UCSF Medical Center involving more than 30 specialists including neurosurgeons, neurologists, and interventional neuroradiologists. The Center offers a complete spectrum of therapies to meet individual patient needs with the highest degree of quality, and is accessible at all times to physicians for consultation, referrals (877/BRAIN-1-1), and transfers.
 
The Center for Stroke and Cerebrovascular Disease has become the leading referral center for cerebrovascular disease in the northern California region, caring for more than 400 aneurysm patients and more than 75 arteriovenous malformation (AVM) patients annually.
 
Many cerebrovascular disorders can be successfully treated with surgery, eliminating the threat of hemorrhage and the risk of death.

Surgical Management of Aneurysms
 
Aneurysms occur in a variety of locations in the brain. Specialized surgical approaches exist to deal with this spectrum of aneurysms. Microsurgical technique is the basis for successful surgical treatment of aneurysms. Aneurysms that lie in subarachnoid spaces and fissures outside the brain can be accessed by carefully opening these natural corridors. Skull base surgery, which utilizes corridors through the bone of the base of the skull, is commonly used for deep and difficult aneurysms. Newer modalities for treating aneurysms, namely occluding them with platinum coils packed inside the aneurysm, are available for selected cases. Complex and giant aneurysms that cannot be treated with conventional clipping or coiling techniques are treated with more intricate procedures, including bypass operations that resupply blood flow to arteries downstream from the aneurysm so that upstream arteries filling the aneurysm can be occluded.
 
Surgical Management of Arteriovenous Malformation (AVM)
 
Most arteriovenous malformations (AVMs) are treated with microsurgical resection. The safety and efficacy of surgery is enhanced by preoperative embolization, an endovascular procedure that selectively catheterizes arteries feeding into an AVM and occludes them with particles or glue. This preoperative technique decreases the flow through an AVM and facilitates its surgical removal. While most AVMs can be treated in this manner, those that are not surgically accessible are treated with stereotactic radiosurgery, or the Gamma Knife®. This approach uses radiation targeted precisely to the AVM to induce changes in the arteries that, over time, occlude them.
 
Surgical Treatment of Vascular Malformations
 
Treatment of dural arteriovenous fistulae (DAVF): These lesions are abnormal artery-to-vein connections in the dura that overlies the brain. DAVFs can usually be treated endovascularly by occluding feeding arteries with embolic agents, or by occluding the venous sinuses on which these fistulas are based. For lesions that are not completely obliterated with endovascular methods, surgery is used to finish the treatment.
 
Treatment of cavernous angioma: These malformations of capillaries and veins are rare, causing seizures or acute, focal neurological deficits that vary with the lesion location. Cavernous angiomas vary in size from a few millimeters to several inches in diameter. These lesions are managed surgically when they are accessible, enabling removal of the malformation and often curing the seizures. Surgical resection requires careful strategy to reach the lesion without going through any vital brain tissue, often relying on intraoperative computer navigation.
 
Surgical Treatment of Ischemic Disorders
 
A stroke occurs every minute. Death from stroke occurs every three minutes. The UCSF Center for Stroke and Cerebrovascular Disease is committed to the rapid diagnosis and treatment of stroke. A physician-to-physician hotline (877/BRAIN-1-1) is available 24 hours a day, seven days a week for emergency consultations, referrals, and transfers to UCSF Medical Center.
 
Radiological evaluation with CT scan, MR imaging and/or angiography is performed promptly to establish a diagnosis within the window for therapeutic intervention, and neurosurgery is available at any time. After extensive evaluation by the Center's team, patients who experience cerebrovascular insufficiency who cannot be treated medically are considered candidates for carotid endarterectomy or extracranial-to-intracranial (EC-IC) bypass surgery.
 
. Carotid endarterectomy - This surgery is helpful in preventing stroke in patients with symptomatic or asymptomatic narrowing of the carotid artery greater than 50 percent. During surgery, the exposed carotid artery is temporarily clamped while the atherosclerotic material is removed and the artery is stitched closed. The clamp is then removed and flow is restored to the artery.
 
. EC-IC bypass surgery - This technique is a promising option for high-risk patients with symptomatic atherosclerotic occlusion of the internal carotid artery. Clinical trials have demonstrated a reduction in subsequent stroke for patients following this surgical intervention.
