Interventional Radiology is a department that treats patients by utilizing radiological imaging methods such as ultrasonography, angiography, tomography and less often magnetic resonance imaging as a guide. The interventions performed at this department are not surgical operations. On the other hand, most of these interventions used to be performed surgically in the past; interventional radiology renders it possible to perform them in non-surgical manner now. Unlike cardiology or ophthalmology, interventional radiology does not concentrate on a single organ or part of the body. It offers treatment options for the various regions of the entire body.

Interventional radiology treatments cover all vascular diseases of the body, aside from cardiac vessels. Treatment techniques performed for this purpose are clearance of vascular occlusions (balloon dilatation, stenting, stripping etc.) angiographic treatment of vascular aneurysms, stopping hemorrhages and embolization of hepatic tumors, myomas and conditions like prostate enlargement. 

Interventional radiology also carries out needle biopsies on all organs and tumors, abscess drainage and temporary or permanent treatment for bile duct and urinary tract occlusions. Treatment of some types of cancers, particularly those afflicting the liver, bones and lungs, are carried out at this department as well. Treatment of varicose leg veins and vascular anomalies (arterial or venous malformation) with or without angiography is another option available at this department. The common characteristic of interventional procedures is that each of them is performed through the tiny hole of a needle without requiring a surgical procedure. These interventions are performed under anesthesia and patients do not feel pain. They are mostly able to return home on the same day as the treatment. Equipment utilized is usually high-tech. 


Interventional radiology procedures are not surgeries. All procedures are performed by gaining access through a tiny needle hole and either in a radiology room or angiography room. They come with substantial advantages over surgical operations: 
  • General anesthesia is not required.
  • All treatments are performed through a thin needle.
  • No surgical scar remains on the body.
  • Patients are often able to receive their treatment and return home on the same day. 
  • Risks are far lower than those of surgery. 
  • Patients return to their daily routines far sooner. 

General anesthesia may still be required in interventional radiology procedures aimed at major conditions like cerebral aneurysm. Otherwise all procedures can be carried out under local anesthesia. In some cases, the patient may be given sedatives through the intravenous route. Sedation relieves patients who may grow concerned, excited or afraid even in some simple procedures like a needle biopsy. Patients are often kept under observation for 2-6 hours after each treatment and then allowed to return home afterwards. They can usually return to their normal routines within the same day or the next day.
