Lenox Hill Neurosurgery offers the most advanced and passionate care for people suffering from vascular diseases of the brain, spinal cord, and head and neck regions. Our experts specialize in the management of complex brain aneurysms, brain tumors, brain and spinal cord AVMs, tumors of the head and neck, stroke, and vascular malformations of the head and neck in adults and children.

By implementing the latest technology to communicate with patients, their family members and other healthcare providers, our surgeons facilitate the understanding of complex problems and create an experience of comfort and amazing results.

Our experts, together with the New York Head and Neck Institute, invented the nationally and internationally recognized Lenox Bypass. Utilizing the most advanced techniques and expertise, our team offers options of cerebral bypass surgery for the treatment of large brain aneurysms, Moya Moya disease, and stroke prevention.

The collaborative enthusiasm of our surgeons enhances their individual skills and creates a safe environment. By utilizing less invasive techniques of Endovascular Neurosurgery, the experts at Lenox Hill Neurosurgery perform coiling for brain aneurysms, embolization of AVMs and sclerotherapy of facial vascular malformations.

A unique collaboration between the Brain Tumor Center and the Endovascular Neurosurgery teams at Lenox Hill Hospital offers the latest Intra-Arterial chemotherapy treatments for the care of patients with brain tumors.

By combining the expertise, dedication, and caring qualities of our surgeons, Lenox Hill Neurosurgery is devoted to maintain a healthy brain.

The Lenox Bypass at North Shore-LIJ

The Lenox Bypass is a new type of intracranial (occurring within the skull) bypass developed and performed by our expert surgeons for the treatment of brain aneurysms that measure more than two centimeters.

The innovative procedure, developed by David Langer, MD,director of neurosurgery at Lenox Hill Hospital, and Peter Costantino, MD, executive director of the New York Head and Neck Institute, improves the safety of these types of bypass by avoiding neck incisions, drilling into the skull and use of long blood vessels required in traditional procedures.

Previous procedures required running a blood vessel from the neck into the brain. Use of a long vessel creates risk of crimping, by turning the head for example. Crimping these vessels can lead to stroke. With the Lenox Bypass, the surgeons run a blood vessel from the brain to behind the cheek. Patients benefit because this direct, safer approach not only eliminates the need for long neck incisions, but also the risk of crimping the vessel through everyday movements.

The creation of the Lenox Bypass was made possible due to the unique, team-based approach of the North Shore-LIJ Health System physicians. By working collaboratively across departments, Dr. Langer and Dr. Costantino were able to combine their skill sets to establish a new procedure that improves patient outcomes and gives renewed hope to those with large aneurysms.

An abstract about four Lenox Bypass cases has been published in the prestigious journal, Neurosurgery. The abstract, Internal Maxillary Artery to Middle Cerebral Artery Bypass: Infratemporal Approach for Subcranial-Intracranial (SC-IC) Bypass, was co-authored by North Shore-LIJ physicians Peter Costantino, MD; David Langer, MD; David Chalif, MD; Amir Dehdashti, MD; Mark Eisenberg, MD; Erez Nossek, MD; Rafael Ortiz, MD; and Avi Setton, MD.
