Mycotic Pseudo-aneurysm of the Ascending Thoracic Aorta After Cardiac Transplantation

Post–liver transplant mycotic aneurysm of the hepatic artery

“…Although rare, mycotic aneurysms have been known to complicate transplant surgery [16,17]. The incidence of mycotic aneurysms complicating liver transplantation is reported to be 0% to 3% [5,7,18].…”

Pseudoaneurysm of Ascending Aorta After Biventricular Assist Device Support

“…1,3 Infection is a well-known associated condition occurring up to 50% of heart transplant patients. 4 In one report from Europe, a pseudoaneurysm arose after a large aortic mismatch in a patient with a history of left ventricular assist device (LVAD) infection. 5 The investigators argued that the site of inflow cannula should be resected and anastomosed at a more distal aortic site, which we attempted to do in our case.…”

Asymptomatic Mycotic Aneurysm of Ascending Aorta After Heart Transplantation: A Case Report

“…After open heart surgery, pseudoaneurysms may develop from suture lines, the site of aortic cannulation, or cardioplegic or vent cannula insertions [2]. Endothelial breaks at mentioned sites cause endothelial cell activation; therefore, the possibility of adherence of micro-organisms on that area is high [3].…”

“…Endothelial breaks at mentioned sites cause endothelial cell activation; therefore, the possibility of adherence of micro-organisms on that area is high [3]. The occurrence of mycotic aneurysms after cardiac transplantation is rare; in more than 30,000 cases performed, only 10 cases of mycotic aneurysm have been reported [2].…”

“…Such aneurysms are more likely to occur in immunosuppressed patients after heart or heart-lung transplantation [2,4,5] and in occasional cases after coronary artery bypass graft (CABG) surgery [1]. However, there is nearly always evidence of persistent or previous infection.…”
