adj. within a blood vessel: describing procedures for imaging the circulation or for treating vascular disorders from within the circulation, including *angioplasty, the placement of *stents or coils in aneurysms (see endovascular aneurysm repair; coiling), and *embolization. Endovascular procedures are usually performed by an interventional radiologist or a vascular surgeon.
(EVAR) a recently developed technique that involves the insertion of a covered metal *stent into an *aneurysm. The stent lines the aneurysm and thereby excludes it from the circulation, preventing further expansion and rupture. The delivery system containing the stents is introduced through the common femoral artery. *Fluoroscopy provides real-time imaging to guide placement of the stents and ensure they are in the correct anatomical position.... endovascular aneurysm repair
