Interventional Radiology

Interventional radiology is a rapidly advancing branch of medicine, the therapeutic part of radiology. In interventional radiological treatments, the variety, complexity and depth of procedures have increased a lot recently. In this way, as the methods and techniques specific to a wide spectrum of processes develop, interventional treatment of more critical and intact patients has become possible.

Interventional Radiology performs surgical or non-surgical treatments of many organ systems, not with a single subject or organ systems such as heart diseases, ophthalmology specialization or urology.

Diseases and treatments served in the Interventional Radiology Department;

Vascular (Vascular) Interventions

The most common is diagnostic classical angiography. However, the most important part is therapeutic procedures using angiographic techniques. These generally include opening narrowed or blocked vessels (balloon angioplasty (PTA), stenting, clot melting / removing), or sealing / bleeding vessels (Embolization).

Neurovascular interventions (related to brain vessels)

Non-surgical treatments of aneurysms (bubble), which are the cause of cerebral hemorrhages, which are frequently encountered in brain vascular treatments, are the opening of the stenosis in the jugular vein and stroke treatments.

Peripheral vascular interventions (related to the vessels of organs outside the brain)

Non-vascular (non-vascular organs) interventions

Removal of parts from organs or tumors; biopsy

Temporary (biliary drainage) or permanent removal of obstruction by intervening in the biliary tract (biliary stent application)

In case of obstruction that prevents urine outflow in the kidney, to temporarily or permanently open urine outflow to ensure kidney survival; nephrosthomy

Discharge of fluid accumulated in the lung; pleural drainage

Discharge of fluid accumulated in the abdominal area; acid drainage

Discharge of inflammation that has accumulated anywhere on the body; percutaneous abscess drainage


Interventional Radiological Therapeutic Methods


Operations in interventional radiology; It guides the diagnosis and treatment of various diseases, using much less invasive methods than surgery, guided by imaging methods such as ultrasonography, fluoroscopy, and tomography. Generally, these procedures are easier for patients. Because there are no large incisions. The processes are completed with less pain, less risk and shorter recovery time.

Interventional radiologists plan catheters (a few millimeters thick plastic tubes) through vessels or percutaneously (through the skin), guided by imaging procedures (Digital Substraction Angiography, Fluoroscopy, Ultrasound, Computed Tomography). These procedures are performed locally or under general anesthesia as required.

Interventional Oncology


The branch of interventional radiology related to cancer is called “Interventional Oncology”.

The most frequently applied procedures in Interventional Oncology;

  • Imaging-guided needle biopsies
  • Placement of chemotherapy port
  • Percutaneous (inserted through the skin with a needle) tumor ablations (tumor burning)
  • Transarterial (administered from the groin or wrist, artery) cancer treatments
