Catastrophic iatrogenic abdominal aorta haemorrhage during anterior resection.

A woman in her 70s with hypertension, breast cancer and diverticulosis underwent laparoscopic anterior resection for a tubule-villous adenoma, converted to open Hartmann's with aorto-bi-iliac bypass due to a vascular injury. Intraoperative complications included haem-o-lok penetration of the calcified aorta, necessitating vascular team intervention. Postoperative issues included bilateral popliteal artery emboli requiring embolectomy and fasciotomy, and a parastomal abscess.

Complete necrosis of graft ureter following renal transplant in a patient with primary antiphospholipid syndrome: A case report.

In a patient with antiphospholipid syndrome, a combination of factors such as arterial thromboembolism, hematoma formation, and surgical collateral damage can cause ischemia of the graft ureter. Preoperative optimization of disease activity and coagulation with meticulous preservation of ureteric perfusion may help in prevention.
