Objectives: This review aims to evaluate the adverse outcomes for patients after treatment with covered stents. Background: Coronary perforation is a potentially fatal complication of percutaneous coronary revascularization which may be treated using covered stents. Studies have evaluated long-term outcomes among patients who received these devices, but hitherto no literature review has taken place. Methods: We conducted a systematic review of adverse outcomes for patients after treatment with covered stents. Data from studies were pooled and outcomes were compared according to stent type. Results: A total of 29 studies were analyzed with data from 725 patients who received covered stents. The proportion of patients with chronic total occlusions, vein graft percutaneous coronary intervention (PCI), intracoronary imaging and rotational atherectomy were 16.9, 11.5, 9.2, and 6.6%, respectively. The stents used were primarily polytetrafluoroethylene (PTFE) (70%) and Papyrus (20.6%). Mortality, major adverse cardiovascular events, pericardiocentesis/tamponade and emergency surgery were 17.2, 35.3, 27.1, and 5.3%, respectively. Stratified analysis by use of PTFE, Papyrus and pericardial stents, suggested no difference in mortality (p = .323), or target lesion revascularization (p = .484). Stent thrombosis, pericardiocentesis/tamponade and emergency coronary artery bypass surgery (CABG) occurred more frequently in patients with PTFE stent use (p = .011, p = .005, p = .012, respectively). In-stent restenosis was more common with pericardial stent use (<.001, pooled analysis for first-and second-generation pericardial stents). Conclusions: Cases of coronary perforation which require implantation of a covered stent are associated with a high rate of adverse outcomes. The use of PTFE covered stents appears to be associated with more stent thrombosis, pericardiocentesis/ tamponade, and emergency CABG when compared to Papyrus or pericardial stents.

“…Some patients underwent CABG with resection of the pseudoaneurysm (3). Other investigators suggested the use of vein graft-coated stent (8) or polytetrafluroethylene (PTFE) graft-covered stents (10). Another case has been successfully treated with IVUSguided primary stenting (2).…”

Chest Pain Due to Late Huge Coronary Pseudoaneurysm Following Stent Implantation

et al. 2011

A 50-year-old man was referred to our hospital because of persistent atypical chest pain. His past medical history was remarkable for a non ST elevation myocardial infarction, treated five months previously with PCI on the right coronary artery. Two months later, for chest pain, he underwent coronary angiography that showed a right coronary artery with slight ectasia near the stent. Five months later for the persistence of atypical chest pain he came to our clinic. Chest CT showed a 31.5 mm hematoma of the right coronary artery. Coronary angiography revealed a giant aneurysm, proximal to the stent. In the light of rapid growth of aneurysm, the risk of rupture and symptoms, we decided to treat the aneurysm with covered stents. The patient underwent successful PCI with regression of symptoms.

“…LM coronary artery pseudoaneurysms were not frequently reported and mostly due to the same causes. [3]. There were four features that made the LM lesion in the current case almost undoubtedly a pseudoaneurysm: rapid growth in a short period of time, irregular contour with a narrow neck, contrast flow into and retention in the dissection plane and a large edematous reaction zone above the large aneurysm on the multi-detector computer tomography images.…”
