Cerebrovascular / Skull Base Surgery /
Endovascular Neurosurgery


The Cerebrovascular / Skull Base Surgery / Endovascular  Neurosurgery Division encompasses the Departments of Neurosurgery, Interventional Neuroradiology, Neurology, and Radiation Oncology, all of which work together with a focus on a multidisciplinary approach to the treatment and care of various neurovascular diseases (diseases affecting the blood vessels of the nervous system).

We treat conditions that affect blood vessels of the brain, neck, and spine including intracranial aneurysms, extra- and intra-cranial atherosclerostic disease, intracerebral hematoma, arteriovenous malformations (AVM), dural arterio-venous fistulae (dAVF), stroke, moyamoya disease, microvascular compression syndromes such as trigeminal neuralgia, and a host of less common conditions. Our team works to develop individualized treatment plans for each patient, as exemplified by weekly cerebrovascular conference, where patients are discussed and reviewed in detail by the multidisciplinary team. In addition, we have multidisciplinary cerebrovascular clinics every week where our team evaluates all patients in a comprehensive manner. Treatment options range from surgical interventions to more conservative treatment with minimally invasive endovascular procedures such as stenting, radiation therapy, and sometimes prescription medication.

When encountered with a neurovascular condition our team of experts meets and decides on the best treatment available. We have the most advanced imaging capabilities including MRI, non-invasive vascular evaluation with MRA and CTA, detailed evaluation of cerebral blood flow using MR perfusion, and conventional cerebral Angiography. If surgery is required our suites and operative rooms are equipped with advanced intraoperative equipment such as intraoperative CT scanners and surgical microscopes with non-invasive ICG monitoring.

Treatment may include neurointerventional surgery, which means treating the blood vessel disease from within the blood vessel itself, using a catheter and imaging technology to precisely target the condition. Many strokes are treated by removing the blood clot from within the blood vessel in this way. Our division’s clinical research is also deeply involved with outcomes and improving care of these patients, as well as those with complex aneurysms treated using flow diverting device, which is an advanced technique used to treat previously untreatable aneurysms.
