Cerebral Revascularization Center

The USC Cerebral Revascularization Center at Keck Medicine of USC specializes in the use of bypass strategies to treat complex diseases such as moyamoya disease, giant or complex cerebral aneurysms, chronic ischemic disease and other rare conditions.

Our program is unique in its expertise in using bypass surgery to solve complex intracranial problems. We are focused on the patient’s functional recovery and aim to prevent disability, maintain quality of life and whenever possible correct any functional gaps that exist from previous strokes. Our team includes expert microvascular surgeons from neurosurgery and plastic surgery. We have a robust surgical team that includes neuroanesthesiologists, nurses, monitoring technicians and scrub technicians who have extensive experience in the techniques required to successfully perform these procedures. Our surgical teams work in concert to reduce surgical time and improve outcomes.

Our treatment strategies are tailored to individual cases based on the patient’s functional status, current symptoms and pathology. Our team has pioneered the use of flow-through flaps in the treatment of complex intracranial disease. These bypasses maintain blood flow to healthy tissue that can be used for direct and indirect revascularization. We also have described unique intracranial bypass techniques that connect healthy vessels within the brain side-to-side in a sequential fashion to treat complex aneurysms.
