Percutaneous panvascular intervention in an unusual case of extensive atherosclerotic disease

Gastrointestinal complications after open heart surgery: incidence and determinants of risk factors

Acute mesenteric ischemia is a rare but serious complication of open heart surgery. Between January 2009 and January 2012, 1360 adult patients underwent open heart surgery with cardiopulmonary bypass at our institution; 29 patients presented gastrointestinal complications. Eight patients developed acute mesenteric ischemia and all of them died. Significant predictors of the complication were New York Heart Association functional class III/IV, history of extensive atherosclerosis and chronic renal failure, acute renal failure following surgery, low cardiac output, use of 2 or more vasoconstrictor drugs, prolonged mechanical ventilation, and multiorgan failure. Atherosclerosis is a multisystemic disease that affects several organs. Radiologic evaluation of mesenteric arterial system should be performed in high-risk patient populations. Perioperative percutaneous and open vascular procedures will reduce the risk of acute mesenteric ischemia that may develop after cardiac surgery and consequent morbidity and mortality rates.
