Endovascular Catheter-Based Aneurysm Repair

In endovascular catheter-based aneurysm repair (EVAR), a catheter - mostly via the femoral artery - to the affected area. Under X-ray control, a tubular endoprosthesis is unfolded there, which seals a leak in the vessel wall, for example during aortic dissection.

The endovascular aneurysm circuit with stent grafts was already described in the 1980s by the Ukrainian surgeon Nikolay L. Volodos. Today, the so-called EVAR (EndoVascular Aneurysm Repair) belongs to the main treatment method for aneurysms. Endovascular aneurysm elimination consists of puncturing the selected access vessels (usually: A. femoralis communis), inserting a sufficiently dimensioned sluice, and imaging the aneurysm using contrast-enhanced digital subtraction angiography (DSA). After angiography, the prosthesis body is positioned. If the proximal and distal landing zone(s) are sufficiently sealed by the prosthesis, the aneurysm is cut off from the blood circulation and thus switched off.
