Coronary artery aneurysms following drug eluting stents implantation: A retrospective analysis from series of cases at tertiary care cardiac centre over three years

Systematic review of the evaluation and management of coronary pseudoaneurysm after stent implantation

“…Using the PRISMA methodology, 36 articles 1‐36 were identified that fulfilled criteria of PSA after stenting in an atherosclerotic lesion in the absence of concomitant infection (Figure 2). With the addition of the present case report (please see below), there are 37 well‐documented and reported coronary PSA cases (Table 1).…”

“…Pseudoaneurysm (PSA) formation is a rare but well‐known complication of coronary stenting 1‐36 . It develops after a perforation disrupts the integrity of the vessel wall but is contained by extravascular thrombosis, fibrosis, and pericardial constraint.…”

Post-infectious pseudoaneurysm after coronary angioplasty using drug-eluting stents

“…Pseudoaneurysms may represent a risk for serious adverse outcomes since they can lead to complications such as thrombosis with distal embolization, rupture, cardiac tamponade, and myocardial infarction [3,4]. Drug-eluting stent (DES) can pose an inherent risk of pseudoaneurysm development by delaying or preventing vascular healing by inhibiting neointimal hyperplasia and by inducing a reaction of hypersensitivity at the point of contact with the coronary endothelium [5,6]. Coronary stent site infections are rare and are presumed to be the result of either direct stent contamination at the time of delivery or transient bacteremia from the access site [7].…”
