Long‐term follow‐up of polytetrafluoroethylene‐covered stents implanted during percutaneous coronary intervention for management of acute coronary perforation

Abstract

Utilization of a PTFE-covered stent may be a reasonable short- and long-term option to manage acute coronary perforation that occurs during PCI. On the basis of this limited experience, successful PTFE-covered stent deployment as the conclusive treatment for coronary perforation is associated with a favorable long-term event-free survival rate.

Retroperitoneal Bleeding and Arteriovenous Fistula after Percutaneous Coronary Intervention Successfully Treated with Intravascular Ultrasound-guided Covered Stent Implantation

“…Our case was consistent with previous cases, and the IVUS guidance made it easy to use an optimal-size covered stent. The use of a covered stent has resulted in long-term favorable outcomes in the management of acute coronary perforation (7). Likewise, our follow-up CT showed no restenosis of the covered stent.…”

Successful management of Ellis type III left anterior descending artery perforation following percutaneous coronary intervention by a covered stent: Successfully resolved the dramatic complication

“…7 Type 1 and 2 perforations are predominately caused by hydrophilic and stiff wires and the course of these is usually mildly symptomatic and does not require pericardial drainage or surgical intervention. 8 Type 3 perforations are more often associated with stent placement by over dilatation or oversized stent placement as might be the cause in our case or during aggressive usage of athero-ablative devices. Most cases of grade III CP can be managed with percutaneous methods.…”

Histologic analysis of a covered stent implanted for pseudoaneurysm in a coronary artery

“…Covered stents have been successfully employed to treat perforations that occur as a complication of PCI [1–5]. Although coronary aneurysms or pseudoaneurysms are known possible complications of stents, especially drug-eluting stents [9,10,11], this case is unusual because leaking occurred not at the site of the stent but 1.5 cm from its edge.…”

“…Covered stents are the standard of care when coronary perforations complicate percutaneous coronary interventions (PCIs)[1,2,3,4,5] and have also been utilized in the treatment of coronary aneurysms [6]. To our knowledge, only histologic evaluation of covered stents deployed in experimental animals have been reported [7, 8] but not following implantation in human coronary arteries.…”
