Endovascular surgical neuroradiology, also known as interventional neuroradiology or endovascular neurosurgery, is a medical subspecialty that focuses on minimally invasive procedures to diagnose and treat conditions affecting the blood vessels of the brain and spine. It involves the use of catheters and small tools that are inserted into the blood vessels to access and treat the affected areas.
Here are some key points about endovascular surgical neuroradiology:
Definition: Endovascular surgical neuroradiology is a specialized field within neurosurgery that combines radiology and neurosurgical techniques to treat vascular disorders of the central nervous system.
Procedures: Endovascular surgical neuroradiology procedures include:
Embolization: This involves blocking or reducing blood flow to abnormal blood vessels, such as aneurysms or arteriovenous malformations (AVMs), using coils, glue, or other embolic agents.
Angioplasty and stenting: This procedure is used to open narrowed or blocked blood vessels in the brain or spine. A balloon catheter is used to widen the vessel, and a stent may be placed to keep it open.
Thrombectomy: This procedure is performed to remove blood clots from blocked blood vessels, particularly in cases of acute ischemic stroke.
Aneurysm coiling: This involves placing tiny platinum coils within an aneurysm to promote blood clotting and prevent rupture.
Arteriovenous malformation (AVM) treatment: AVMs are abnormal tangles of blood vessels. Endovascular surgical neuroradiology can be used to block or remove these abnormal vessels.
Benefits: Endovascular surgical neuroradiology offers several advantages over traditional open surgery, including:
Minimally invasive: The procedures are performed through small incisions, resulting in less trauma to the body and faster recovery times.
Reduced risk: The risk of complications, such as infection and bleeding, is generally lower compared to open surgery.
Targeted treatment: The procedures allow for precise targeting of the affected blood vessels, minimizing damage to surrounding tissues.
Training: Physicians specializing in endovascular surgical neuroradiology undergo extensive training, including a residency in radiology or neurosurgery, followed by a fellowship specifically focused on interventional neuroradiology.
