Case ReportsPresentation and treatment of spontaneous aortocaval fistula.
Spontaneous rupture of abdominal aortic aneurysm into the inferior vena cava is rare. The clinical presentation is highly variable, and the diagnosis can be difficult, often being made only at operation. The aortocaval fistula results in a large left-to-right shunt, which can cause cardiac failure. Once the diagnosis is made, treatment is by surgical closure of the fistula and repair of the aneurysm with a graft. ⋯ Spontaneous aortocaval fistulas are uncommon, and their preoperative recognition is difficult. Hematuria in association with an abdominal aortic aneurysm should raise the suspicion of an aortocaval fistula. Surgical correction is possible, with survival rates comparable to those associated with rupture of aneurysms into the retroperitoneum. Early operative control of the fistula is important to optimize the preload to the heart.

Case ReportsAcute colonic pseudo-obstruction complicated by cecal perforation in a patient with Parkinson's disease.
Acute colonic pseudo-obstruction (Ogilvie's syndrome) is characterized by physical examination and radiologic findings indicative of mechanical obstruction but in which no physical obstructive process can be found. Many factors have been associated with this syndrome which include electrolyte imbalance, systemic infection, drugs, and occasionally, neurologic disease. Reported here is a case of acute colonic pseudo-obstruction which developed in a patient with known Parkinson's disease and was complicated by cecal perforation, yet had a favorable outcome.
