Dressing changes in the immediate postoperative period are not necessary. Applying a sterile dressing in the operating room may serve as a barrier to nosocomial pathogens during hospitalization. Our data suggest this dressing change protocol may lead to reduced SSI risk. Leaving the original postoperative surgical dressing intact is safe, simple, and cost-effective.

SUMMARYA 47-year-old man with diabetes and hypertension presented with sudden onset of chest pain and subsequently developed expressive aphasia. Brain imaging revealed multiple areas of ischaemic infarcts. Transoesophageal echocardiogram revealed aortic dissection with a free-floating thrombus on the dissection flap, which was the source of emboli. Given the poor prognosis, surgical intervention was not pursued and artificial support was withdrawn. Aortic dissection is a highly fatal condition with varied presentation including heart failure, myocardial infarction, neurological deficits, abdominal pain or acute renal failure. Aortic dissection is a relatively uncommon but catastrophic condition. A high degree of clinical suspicion is required for early and accurate diagnosis since mortality is high and increases by the hour. The mechanism for stroke in our case was due to an arteryto-artery embolism from a thrombus, which developed on the intimal surface of the dissected artery. This is an infrequent complication with a very unique mechanism. BACKGROUND
