Endovascular Neurosurgery

Endovascular Neurosurgery, also known as neurointerventional surgery is a subspecialty within neurosurgery. Our neurosurgeons use catheters and radiology to diagnose and treat many conditions of the central nervous system, which includes the brain and spine.

Our Expertise in Endovascular Neurosurgery 

Our own Dr. Joshua Marcus and Dr. Jonathan Lebovitz specialize in minimally invasive surgical techniques that may need to be done to improve a patient’s health. The neurovascular surgery program at Elite Brain and Spine combines knowledge to treat our patients. 

Subdural Hematoma Embolization

A Subdural Hematoma Embolization is a minimally invasive procedure that is used to relieve pressure on the brain by using a microcatheter and medications caused by a subdural hematoma. Once the microcatheter is in place, medications are released through it to block the blood flow to the hematoma. 


Here at Elite Brain and Spine, our specialists perform this procedure minimally invasively using live X-ray visualization and a microcatheter. The steps to the procedure are listed below: 

  1. Incision. A very tiny incision is made on the arm or leg. The microcatheter is then placed through it. 
  2. Microcatheter placement. A contrast material is placed through the catheter. After, X-rays are taken to make sure it is perfectly positioned to the hematoma. 
  3. Medication Released. A medication or synthetic material is released through the microcatheter. 
  4. Close. The incision is closed and covered with dressings. 

The length of the procedure can vary depending on the complexity of the hematoma. It may take only 30 minutes, but it could take up to a couple of hours. Usually, patients will be able to leave the same day as the procedure. Our board-certified neurosurgeons have performed thousands of Subdural Hematoma Embolizations, so you are in the best hands! 

Microvascular Decompression

Microvascular Decompression is endovascular neurosurgery that can be done minimally invasive. It is used to relieve compression of the cranial nerve. It involves opening the craniotomy (skull) and inserting a sponge between the nerve and offending artery triggering the pain signals and decompressing the nerve.  


Microvascular Decompression is performed as an inpatient procedure. There are 4 steps that are performed throughout the surgery: 

  1. Incision. A tiny incision is made in the brain. 
  2. Craniectomy.  A craniectomy is performed to expose the brain. 
  3. Expose the nerve. Tiny retractors and instruments are used to expose the compressed nerve.
  4. Insert Sponge. A sponge is placed on the nerve and adjacent artery.
  5. Place Plate & Screws.  A small plate and screws are placed over the bone that was removed during the craniectomy. 
  6. Close. The incision is carefully closed. 

The procedure lasts about two to three hours. Once the procedure is finished, the patient is taken to the neurovascular care unit. The patient will usually stay between one and two days which will be decided between you and your surgeon. At Elite Brain and Spine, all of our top neurosurgeons have performed countless endovascular neurosurgeries, like microvascular decompressions.

Skull Base Surgery

Skull Base Surgery is a minimally invasive procedure that is used to remove and diagnose abnormalities. Such abnormalities include tumors at the base of the skull, in the cervical vertebrae or on the underside of the brain.  


At Elite Brain and Spine, the surgery is performed as an inpatient procedure. The surgery is minimally invasive. The steps to the procedure are: 

  1. Incision. A tiny incision is made in the skull, nose, or mouth. Your surgeon will determine the best entry point.
  2. Diagnosing the abnormality. An arthroscopic camera and television monitor are used to locate and view the abnormality. It is possible when the surgeon sees the abnormality, they may be able to have an idea of a diagnosis. 
  3. Removing the abnormality. Tiny instruments are used to remove the abnormality.
  4. Close. The incision is closed and covered with dressings. 
  5. Analyze. The abnormality is then sent to be analyzed. 

The total time of the procedure is usually one to two hours. After the procedure, the patient is taken to the neurovascular care for one to two days. 

Luckily at Elite Brain and Spine, our specialists are experts on this endovascular neurosurgery. They have performed thousands of skull base surgeries so you will be in the best hands!
