Chylooperitoneum in the cardiovascular possurgical. Presentation of a case

Chyloperitoneum is defined as the presence of lymph of thoracic or intestinal origin in the abdominal cavity. It is reported infrequently and is a rare manifestation of multiple deseases. Most of the cases are secondary and are associated with direct trauma to the peritoneal dialysis. Renal replacement therapy is necessary in up to 10% of children who undergo cardiac surgery with extracorporeal circulation, indicated in cases of water overload, acute renal dysfunction or ionic alterations. Objective: To report the case of a 15-day-old newborn, operated on for Transposition of the Great Vessels, who presented as a postoperative complication, dicharge of chylous content through the Tenckhoff, after a peritoneal dialysis regimen due to acute renal failure and fluid overload. Results: Despite the therapeutic measures taken, the patient maintains centuries-old losses of lymph, which lead to nutritional and immunological deterioration with the consequent multiple organ dysfunction and death. Conclusions: The perpetuation of lymph losses in the postoperative period of cardiovascular surgery produces a nutritional and immunological deterioration of the patient, with a high risk of mortality due to sepsis.
