Neurovascular surgery is a branch of medicine that deals with the diagnosis, treatment, and prevention of diseases that affect the brain and spinal cord, including their blood vessels. These procedures are performed to address a wide range of conditions, including stroke, brain aneurysms, arteriovenous malformations, or AVMs and brain tumors.

The BOBÌåÓý difference

The neurovascular program at BOBÌåÓý Shands Hospital is one of the leading programs in the nation for comprehensive cerebrovascular and endovascular neurosurgery. The team performs nearly 1,000 procedures annually. This includes endovascular and open cerebrovascular surgery to treat many of the most complex neurovascular diseases. The BOBÌåÓý neurovascular team performs many of the latest endovascular neurosurgical procedures using image-guidance technology for both diagnosis and treatment.

What is endovascular neurosurgery?

Endovascular neurosurgery is a minimally invasive form of neurovascular surgery. It uses a catheter-based approach to diagnose and treat conditions of the brain and spinal cord. This technique allows the surgeon to access the patient's vascular system through a small incision in the groin area. This reduces the need for open surgery and minimizes recovery time. Endovascular neurosurgery is often used to treat aneurysms, AVMs and certain types of stroke. The term endovascular means “inside a blood vessel.�

795,000 people in the United States each year with an ischemic stroke. Of those about one-third, or nearly 235,000, have a large vessel occlusion. This means they could be candidates for endovascular surgery after stroke. This can have an overwhelmingly positive effect on outcomes.

Recent studies show that people who had endovascular surgery to treat stroke were more likely to return to normal life than people who received medical treatment only.

How are endovascular procedures performed?

Doctors that specialize in endovascular neurosurgery use tools that pass through blood vessels to diagnose and treat diseases and conditions rather than using open surgery. These tools include radiology images that allow the doctor to see the part of the body involved in the procedure. Doctors in this specialty may also diagnose and treat spinal cord conditions using similar techniques.

What is cerebrovascular neurosurgery?

Cerebrovascular neurosurgery is a form of neurovascular surgery. It specifically focuses on the blood vessels of the brain and conditions associated with those vessels. This type of surgery is performed to treat conditions such as:

• Aneurysms
• AVMs
• Stenosis (narrowing of blood vessels)
• Embolism (blockage of blood vessels)

By using advanced techniques and technologies, cerebrovascular neurosurgeons are able to restore normal blood flow to the brain and prevent life-threatening conditions.

Neurovascular procedures

The UF neurovascular surgeons performs almost 1,000 procedures every year. These include:

• AVM, or arteriovenous malformation surgery
• Aneurysm clipping
• Balloon angioplasty
• Carotid endarterectomy
• Cerebral Cavernous Malformation Surgery
• Coiling of aneurysms
• Combination cerebrovascular/endovascular procedures
• Craniotomy
• Diagnostic angiography
• EC-IC bypass for complex brain aneurysm, ischemic stroke and Moya Moya disease
• Embolization of arteriovenous malformations
• Embolization of tumors
• Embolization of vein of Galen malformations and other pediatric neurovascular procedures
• Endovascular thrombectomy for treatment of acute ischemic strokes
• Intracranial and extracranial angioplasty and stent placement
• Obliteration of arteriovenous fistulae
• Resection of spinal arteriovenous malformations
• Stenting for aneurysm
• Vertebroplasty or kyphoplasty for spinal compression fracture

The BOBÌåÓý neurovascular surgery team are a vital part of the BOBÌåÓý Shands Comprehensive Stroke Center.

Neurovascular clinical trials

The team actively participates in many cerebrovascular/endovascular clinical trials where the latest high-technology devices are constantly being evaluated and perfected for improved patient care. An active research laboratory focuses on prevention and treatment of stroke, intracranial aneurysms and arteriovenous malformations.

UF is an active participation site for many cerebrovascular and endovascular clinical trials. The latest technological advances are constantly being evaluated and perfected for enhanced patient care.

UF is the clinical coordinating center for the , a national clinical trial evaluating stroke prevention approaches and supported by a $38 million NIH award.

With numerous grants from the NIH, Brain Aneurysm Foundation, American Association of Neurologic Surgeons Neurosurgery Research and Education Foundation, Thomas Maren Foundation, and others, Dr. Hoh’s laboratory performs research investigating:

• How aneurysms form and break to understand them better.
• They're testing how changes in blood flow can cause aneurysms to form in various experiments.
• Biologic and tissue-engineered therapies are being developed for the treatment of aneurysms, using innovative techniques and models.

The identification of cytokines and other factors responsible for aneurysm formation and rupture using human cerebral aneurysm tissue.

The neurovascular surgery team also operates the neurovascular-neurotrauma lab. The team has developed a clinical platform to investigate proteomics and their potential use in acute brain injury. In addition, the lab is involved in NIH-funded work in collaboration with other academic medical centers.

Numerous studies are also underway in the area of cerebrovascular surgery. Among them is research into proteomics and biomarkers in acute brain injury from aneurysmal subarachnoid hemorrhage to determine if specific biomarkers can be used to define specific events occurring in the injured brain.
