Neuro and Vascular Interventional Radiology

Interventional Radiology is a branch of medicine that performs minimally invasive procedures utilising image guidance for diagnosing and treating various diseases. These procedures are often carried out by an interventional radiologist who is trained and skilled in accessing various deep-seated internal structures and organs of the human body through pin-hole incisions, using various imaging modalities like X-ray, fluoroscopy, ultrasound scan, CT scan etc.

These are done either by directly placing small needles into the target area from skin or by reaching the target using small catheters and other sophisticated devices through tubular structures like blood vessels, biliary tract, urinary tract etc. These procedures are minimally invasive and will leave only a pinhole-size wound, which implies the patient may require only a short hospital stay and recovery time.

Diseases which are treated with the scope of interventional radiology are mostly related to blood vessels and can be accessed through them. These include diseases affecting blood vessels like aneurysms, AV malformations, thrombosis/block of blood vessels. These procedures are also utilised in controlling bleeding due to injury, tumours, and other diseases conditions with high vascularity. Most of these conditions are otherwise treated by invasive surgical procedures that demand a longer period of hospital stay and recovery.

Interventional radiologists treat diseases affecting various areas and organs of the human body from head to toe. Thus, we work in close association with various specialists as a multidisciplinary team to provide optimal and effective patient care.

SUT hospital is equipped with an advanced stroke and multidisciplinary ICU which is managed by experienced intensivists round the clock for peri-procedural care.
