title: [Intravascular ultrasound guided polytetrafluoroethylene coronary stent graft implantation in a patient with a large coronary pseudoaneurysm at eight months after coronary intervention: a case report].
abstract: A 67-year-old man with exertional angina presented with a large pseudoaneurysm of the right coronary artery at eight months after balloon angioplasty. Intravascular ultrasound revealed a large saccular pseudoaneurysm of 10.9 x 5.7 mm diameter at the proximal segment of the right coronary artery. Complete closure of the coronary pseudoaneurysm was successfully obtained using a coronary stent graft consisting of a thin flexible polytetrafluoroethylene (PTFE) membrane placed between two stents using a unique sandwich technique. Follow-up angiography and intravascular ultrasound revealed no significant restenosis in the PTFE stent graft segment. PTFE coronary stent graft implantation is a feasible, safe and useful method to treat a large coronary pseudoaneurysm after coronary intervention.
