Unlike true aneurysms, PSAs do not have all the three layers of the vessel in the aneurysmal wall. The PSAs are most commonly seen after an overzealous percutaneous coronary intervention (PCI) which causes damage to the vessel wall. They usually develop slowly after PCI and PSAs within a month of a PCI are not so common. The PSA may be asymptomatic or present with recurrent angina.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>Here, we report a case of symptomatic PSA to right coronary artery (RCA). The patient had a myocardial infarction for which a PCI was performed to deploy a drug-eluting stent (DES) in the RCA. The patient had in-stent restenosis (ISR) within a week of PCI for which plain old balloon angioplasty (POBA) was performed. The patient continued to have unstable angina and within a month of POBA was diagnosed as a case of PSA by intravascular ultrasound. A covered stent was deployed which effectively sealed off the PSA and resumed normal blood flow to distal vessel. Patient has been doing well on medication [aspirin 75\u2005mg once daily, atorvastatin 80\u2005mg once daily, and P2Y12 platelet inhibitor (Ticagrelor) 90\u2005mg twice daily].<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>The PSAs usually take 6\u20139 months to develop. However, PSAs have been reported within 1\u20132 months of PCI. This case also shows that PSAs can occur within a month of PCI. It is possible that over-aggressive and\/or high-pressure dilatation and\/or deep engagement during POBA performed to open up the ISR could have damaged the struts of the DES and compressed it against the vascular wall. The resultant vascular wall injury could have been the cause of early PSA formation in this case. Hence, cardiologists should be vigilant enough to suspect PSA, especially in a patient presenting with angina. The case also shows that covered stents are a viable option to treat early presentations of PSA.<\/jats:p>\n
