Covered Calibration Technique for an Aneurysmal Dilatation on a Saphenous Vein Graft

Abstract

We described a simple technique for calibrating an aneurysmal dilatation on a saphenous vein graft (SVG). The SVG with segmental dilatation is passed through a short section of the saphenous vein, and the dilatation is covered by the short cylinder of the vein. Both parts are fixed by arterial pressure, which expands the SVG. This technique was used in three SVG in three patients who underwent coronary artery bypass grafting. The patency without dilatation was confirmed by angiography one year after surgery in two patients. This simple method is feasible to repair an aneurysmal dilatation on the SVG.
