Neurointerventional surgery is a subspecialty specializing in minimally invasive image-based technologies and procedures used in diagnosis and treatment of diseases of the head, neck, and spine. In these procedures, very thin catheters or wires placed through blood vessels in groin and are navigated in the blood vessels to the disease site followed by diagnostic (Cerebral or Spinal Angiography) or therapeutic procedures.
The therapeutic procedures are done instead of open surgery or to supplement the conventional surgery for Intracranial Aneurysms, arterial stenosis, stroke (Brain attack), Arteriovenous Malformations, Vertebroplasty and Percutaneous Sclerotherapy. Sometimes Tumour Embolisation is done to reduce bleeding during surgery. The latest flat panel Bi-Plane digital subtraction angiography (DSA technology) gives high-resolution images with decreased radiation exposure. The endovascular approach ensures minimal injury to normal brain with fewer complications, better outcome and shorter hospital stay. It enables treatment of diseases, which could not be treated in the past.
