Autologous vein-coated stent for exclusion of a coronary artery aneurysm: case report with postimplantation intravascular ultrasound characteristics.
This report describes the successful use of an autologous cephalic vein-coated coronary stent to exclude an aneurysm of the distal right coronary artery. Post-implantation angiography confirmed successful exclusion of the aneurysm with no evidence of leakage. Intravascular ultrasonography showed complete apposition of the stent to the arterial wall proximal and distal to the aneurysm. The vein could be seen clearly around the stent. Symmetrical stent expansion (minimal luminal diameter, 2.8 mm) was verified. Increased echogenicity in the excluded aneurysm indicated early thrombus formation. Evidently, this is the 1st report of the successful use of an autologous cephalic vein-coated coronary stent to exclude an aneurysm of the distal right coronary artery.
