Spontaneous splenorenal shunt in a patient with antiphospholipid syndrome: the first case reported.

The antiphospholipid syndrome (APS) is an autoimmune disorder, characterized by a wide spectrum of clinical manifestations. Thromboembolic events, with a greater involvement of extremities veins, are the most common features, and obstruction of abdominal vessels are sporadically reported. We present a singular case of a patient with primary APS (PAPS) that developed a spontaneous splenorenal shunt, secondary to a total portal, mesenteric and splenic vein thrombosis. Spontaneous splenorenal shunt, an uncommon circumstance reported in cirrhotic disease, to the best of our knowledge, has not been previously described in PAPS.
