Endovascular Neurosurgery or Interventional Neuro Radiology is a subspecialty of Radiology and Neurosurgery in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes such as Cerebral Angiograms, while others are done for treatment purposes, such as Cerebral Coilings or Embolizations. X-rays are used to direct these procedures, which are performed using thin tubes called catheters. The catheters are introduced into the vascular system either through the Groin, the arm, or sometimes the neck.

Interventional Neuroradiology is a ground-breaking technology for patient management in many Neurovascular diseases currently. This minimally-invasive, advanced technique has several benefits over conventional surgeries like non-opening of the Skull vault, less procedure time, less Anaesthesia time, less ICU stay, less hospital stay, early mobilization, faster recovery, early rehabilitation, and early resumption of the quotidian life.

Dr.K J Harsha

Consultant and Head of the Department of Neuroimageology and Endovascular Neurosurgery

This rapidly developing subspecialty is available at IAH, and has rendered possible the treatment of vascular malformations as Aneurysms with a degree of precision security and success rate that was previously unthinkable. The following procedures are available at IAH done under the supervision of highly qualified and experienced Endovascular Neuro Radiologists who are specially trained in this speciality.

Diagnostic Cerebral / Spinal Angiogram (DSA)

Endovascular treatment of Aneurysms using minimally invasive technique of accessing the Aneurysm from within the bloodstream, specifically during angiography with a high success rate.

Other Cerebral, Head & Neck Vascular malformations:

Other vascular and related diseases are treated endovascularly. Certain facial Lymphangiomas and Hemangiomas are treated by direct puncturing and injecting Sclerosant agents under flouroscopic guidance, hence avoiding major surgeries.

neuro-rehab-services-keralaBasilar Artery Aneurysm Coiling
A 70 year old lady was admitted into Indo American Hospital with sudden onset of severe headache followed by vomiting and loss of consciousness for a few minutes. She had been taken to local hospital and was evaluated at first. CT scan of head showed bleed (Subarachnoid haemorrhage – SAH) & she was referred to our hospital for further treatment. She underwent a CT angiogram, which showed Basilar Artery Aneurysm. Ruptured Aneurysm (balloon like out pouching from artery) is one of common cause of spontaneous haemorrhage in the Brain. As open surgery in this location is difficult and has more complications the patient underwent key-hole surgery (Endovascular Neurosurgery) – coiling of aneurysm – a best suited treatment option in this case. Coiling involves placing small coils directly into the aneurysm, effectively filling it up and preventing blood from entering it, performed from key-hole in groin artery. Blood filling into aneurysm was completely stopped and after surgery, the patient did well.
