Interventional Radiology Department

Interventional Radiology Department

Interventional Radiology (IR) is a medical sub-specialty of radiology which provides minimally invasive image-guided procedures to diagnose and treat of diseases in nearly every organ system. The concept of interventional radiology is to diagnose and treat patients using the least invasive techniques currently available in order to minimize risk to the patient and improve outcomes. These procedures have less risk, less pain and less recovery time in comparison to open surgery. 

All invasive procedures can have complications.  While the risk is low it is not zero. The most common complications are related to the access site. Some bruising is common post procedure, patients may experience a little pain. Allergic reaction to contrast dye, can lead to the development of kidney failure.
