Cerebral bypass surgery


Cerebral bypass surgery is a procedure that is similar to a cardiac bypass procedure but is performed on an artery in the brain. This procedure is used to treat cerebral artery stenosis when there is the narrowing of an artery in the brain that is either completely or partially blocked.

One new type of cerebral bypass surgery, developed at Northwell Health’s Lenox Hill Hospital is the Lenox Bypass . This advanced procedure improves the safety of aneurysm treatment by eliminating the need for neck incisions, drilling into the skull or using long blood vessels. The Lenox Bypass was developed for the treatment of brain aneurysms that measure more than two centimeters. 

The Northwell Health Neuroscience Institute approach

The specialized teams at the Neuroscience Institute’s Brain Aneurysm Center and Center for Cerebrovascular Surgery and Endovascular Neurosurgery provide the most advanced treatment options for brain aneurysms, cerebral hemorrhage, arteriovenous malformations (AVMs), vascular malformations and cavernous angiomas.  These include leading-edge cerebral bypass surgery options, such as the Lenox Bypass. Collaborating with the departments of Neurosurgery, Interventional Neuroradiology, Neurology and Radiology Oncology, we are focused on providing treatments that offer the best chance for a successful outcome.
