IntroductionTransient cortical blindness (TCB) is an infrequent and intriguing postoperative complication following cardiac surgery. It is characterized by the sudden and temporary loss of vision in both eyes, usually resolving within hours (1). By reporting this rare occurrence of TCB after coronary artery bypass grafting (CABG) surgery, we aim to raise awareness among clinicians and researchers about this potential complication.

IntroductionA permcath is a long, flexible tube that is inserted into a vein, most commonly in the neck. It is mostly used as an alternative and long-term access in end-stage renal disease patients requiring hemodialysis. Pneumothorax, hemothorax, arrhythmias, and endocarditis are some of their complications (1). Kidney involvement with COVID-19 infection is a well-known complication, with the majority of them having acute tubular injury which resolved eventually. A few cases needed long-term hemodialysis and only a few cases had developed endocarditis due to permcath insertion with subsequent recovery (2). In this case report, we present a case of a 29-year-old man who has suffered from endocarditis after several hemodialyses through permcath due to COVID-19-induced renal failure.
