Endovascular neurosurgery is a minimally invasive subspecialty of neurosurgery that focuses on diagnosing and treating vascular disorders of the brain, spinal cord, and head and neck vessels. Using catheters inserted through arteries, usually via the groin or wrist, surgeons can navigate the intricate blood vessels to perform both diagnostic and therapeutic interventions without open surgery. Diagnostic procedures, such as digital subtraction angiography (DSA), provide precise imaging to identify aneurysms, arteriovenous malformations (AVMs), stenosis, or vascular malformations. Therapeutically, endovascular techniques include coil embolization of aneurysms, flow diversion, AVM embolization, carotid artery stenting, and mechanical thrombectomy for acute stroke, allowing treatment of complex and deep-seated lesions with reduced risks. This approach shortens recovery time, minimizes complications, and offers a safe, effective alternative to conventional open surgery.

• Minimally invasive technique using arterial catheters.
• Diagnostic interventions: Digital Subtraction Angiography (DSA), CT Angiography (CTA), MR Angiography (MRA).
• Treats lesions that are difficult to reach via open surgery.
• Reduces surgical risks, hospital stay, and recovery time.
• Requires advanced imaging, precise catheter navigation, and specialist expertise.
