Complications of aortic aneurysm surgery: prevention and treatment.

The most common complications associated with resection of aneurysms of the thoracic and abdominal aorta are: hemorrhage, acute renal failure, ischemic colitis, distal emboli, graft thrombosis, infection, pseudoaneurysm formation, aorto-caval and aorto-enteric fistulae, neurologic deficits, ureteral obstruction, sexual dysfunction, chylous ascites and perigraft seroma. Complications can be immediate or late sequelae, insiduous or life threatening. Their prevention and treatment, should they occur, will be discussed.

Amebic abscess of the liver: surgical aspects.

During the past five years, ten documented cases of hepatic amebic abscess have required surgical intervention at Olive View Hospital, Van Nuys, California. Three of the patients underwent laparotomy when an hepatic abscess ruptured into the peritoneal cavity, and two required surgical intervention when an abscess invaded adjacent organs. Another abscess continued to enlarge despite metronidazole therapy and still another became superinfected with bacteria. In the remaining three patients, surgical procedure would have been avoided if the correct diagnosis had been made. In fact, the preoperative diagnosis in five cases was acute appendicitis. All patients survived. The incidence of Entamoeba histolytica infestation is increasing in our community. Although most patients rapidly improve with metronidazole therapy, surgical complications do arise and diagnoses are missed. This series of cases emphasizes the need for surgeons working in Southern California to familiarize themselves with the clinical features, complications and appropriate surgical treatment of amebiasis.
