RESUMO
A 65-year-old man (blood type O) came to our hospital for transplant of an unrelated kidney (6/6 mismatch of HLA genotype) donated by his living 60-year-old wife (blood type B). The planned right donor nephrectomy was uneventful, with a warm ischemic time of 5 minutes, but her right renal vein was too fragile and weak to be repaired for vascular anastomosis. Therefore, we used an artificial vascular graft (polytetrafluoroethylene) interposed between the donor renal vein and the recipient's left external iliac vein. On the 11th day after surgery, infraphrenic free air (identified by a chest radiograph) made us do an emergent laparoscopic examination that showed a perforation of his sigmoid colon. A transient transverse colostomy was therefore prepared. The transient transverse colostomy was closed 8 months after the kidney transplant. Twelve months after the transplant, the patient is doing well with a serum creatinine level of 150.44 micromol/L (1.7 mg/dL).
