It is a subdivision of radiology and its branches within itself. Interventional Radiology involves the diagnostic and treatment methods performed by entering the body through the path of small puncture, without forming a surgical incision. Within itself, the unit deals with vessel problems is called vascular interventional radiology, the unit that deals with the remaining extravascular areas of the body is called non-vascular interventional radiology (extravascular interventional radiology).
In vascular interventional radiology the method is the intravenous treatment of diseases (endovascular treatment). This method is currently being used extensively in the treatment of arterial and venous obstructions, aneurysms of cerebral vessels and other arteries, venous insufficiencies and varices in the legs. With endovascular treatment, some benign or malignant tumors can also be treated by administering drugs from the feeding arteries or by blocking the feeding vessels.
Extravenous interventional radiology is a special interventional procedure performed by needle insertion through the skin. It includes; draining any abscess or fluid build-up from abdominal cavity or chest cavity with special devices from the skin. Draining kidney cysts through the skin when they harm the patient (drainage of the abscess). Evacuation of the urine through the skin (nephrostomy) or maintaining passage into the bladder (antegrade ureteral stent) to prevent the urine from causing damage to the kidneys in the kidney and urinary tract obstructions. In the liver, bile duct or pancreas diseases, the removal of the bile from the skin or the opening of the obstruction with balloon and stent in order to prevent the bile from damaging the body in case of bile duct obstruction, especially removing parasitic cysts (cyst hydatid) from the liver through the skin and drying by a special treatment.
The advantages of interventional radiology are making the procedures closed, not having incision, focusing on the problematic point directly and applying the smallest possible intervention to the patient. Therefore, the length of hospitalization is shorter and the healing process is faster than the surgical procedures.
