Common Procedures Performed

Interventional neurologists perform a variety of procedures, each tailored to address specific neurological conditions. These procedures are typically minimally invasive, utilizing catheters and imaging guidance to target the affected area. One of the most common and critical procedures is mechanical thrombectomy for acute stroke. In this procedure, a catheter is inserted into an artery, usually in the groin, and guided to the blocked blood vessel in the brain. A specialized device is then used to remove the clot, restoring blood flow to the affected area. The speed and efficiency of this procedure are crucial in minimizing brain damage and improving the chances of a full recovery. Another frequent procedure is the endovascular coiling of brain aneurysms. An aneurysm is a weak spot in a blood vessel that can bulge and potentially rupture, leading to a life-threatening hemorrhage. During coiling, a catheter is used to deliver tiny platinum coils into the aneurysm, filling the space and preventing it from rupturing. This procedure is a less invasive alternative to traditional surgical clipping of aneurysms. Embolization of arteriovenous malformations (AVMs) is another important procedure. AVMs are abnormal tangles of blood vessels that can disrupt normal blood flow and cause bleeding in the brain. Embolization involves injecting a special glue-like substance into the AVM to block off the abnormal vessels and prevent further bleeding. Interventional neurologists also perform angioplasty and stenting to treat carotid artery stenosis, a narrowing of the carotid arteries that can increase the risk of stroke. During angioplasty, a balloon catheter is used to widen the narrowed artery, and a stent is then placed to keep the artery open. Other procedures include thrombolysis for dissolving blood clots, venous sinus stenting for treating venous sinus stenosis, and ** Wada testing** to determine language and memory dominance before surgery. Each of these procedures requires specialized skills and expertise, as well as advanced imaging technology to ensure precision and safety. Interventional neurologists undergo extensive training to master these techniques and provide the best possible care for their patients. The field is constantly evolving, with new procedures and technologies being developed to further improve the treatment of neurological conditions. As a result, interventional neurology plays an increasingly vital role in the management of a wide range of neurological disorders, offering hope and improved outcomes for patients who previously faced limited treatment options. The minimally invasive nature of these procedures translates to less pain, shorter hospital stays, and quicker recovery times, making them an attractive alternative to traditional surgery. The collaboration between interventional neurologists and other specialists, such as neurologists and neurosurgeons, ensures that patients receive comprehensive and coordinated care. With ongoing advancements in technology and techniques, the future of interventional neurology looks promising, with the potential to further revolutionize the treatment of neurological diseases. This dynamic field continues to push the boundaries of medical innovation, offering new possibilities and improved quality of life for individuals affected by complex neurological conditions.

Conditions Treated

Interventional neurology addresses a wide spectrum of neurological conditions, focusing primarily on vascular disorders affecting the brain and spine. Stroke, both ischemic (caused by a blockage) and hemorrhagic (caused by bleeding), is a primary target for interventional treatments. In acute ischemic stroke, interventional neurologists perform mechanical thrombectomy to remove blood clots and restore blood flow to the brain, significantly reducing the risk of permanent disability. Brain aneurysms, which are weak spots in blood vessels that can rupture and cause life-threatening bleeding, are also commonly treated using endovascular coiling or flow diversion techniques. These minimally invasive approaches offer a safer and more effective alternative to traditional surgical clipping. Arteriovenous malformations (AVMs), abnormal tangles of blood vessels that can cause bleeding or seizures, are another condition frequently managed with interventional techniques. Embolization, where a special glue-like substance is injected into the AVM to block off the abnormal vessels, can prevent further bleeding and reduce the risk of neurological damage. Carotid artery stenosis, a narrowing of the carotid arteries that can increase the risk of stroke, is treated with angioplasty and stenting to improve blood flow to the brain. Interventional neurologists also address venous sinus stenosis, a narrowing of the venous sinuses in the brain that can cause headaches, vision problems, and other neurological symptoms. Stenting of the venous sinuses can relieve the pressure and improve blood flow. Other conditions treated include dural arteriovenous fistulas (dAVFs), abnormal connections between arteries and veins in the dura mater (the outer covering of the brain and spinal cord), and spinal vascular malformations. Interventional techniques can also be used to deliver medications directly to the brain or spine, bypassing the blood-brain barrier and maximizing therapeutic effects. The field of interventional neurology is constantly expanding, with new applications being developed for the treatment of other neurological conditions, such as tumors and epilepsy. The minimally invasive nature of these treatments makes them particularly appealing for patients who may not be good candidates for traditional surgery.
