With the Certificate of Proficiency in Interventional Angiology, doctors with a specialist qualification in angiology acquire the competence to independently perform diagnostic and therapeutic procedures and interventions on peripheral arteries or veins.

Interventional angiology is used to treat vascular diseases such as venous thrombosis or occlusion of arteries.  The field of interventional angiology covers all blood vessels with the exception of arteries and veins in the heart and brain. Various methods (balloon catheters, stents) are used to reopen narrowed or blocked arteries or veins. The X-ray-assisted procedures are usually performed percutaneously under local anaesthesia. Percutaneous means that the catheters are inserted through the skin into the arteries or veins.
