[Detection of superior mesenteric vein thrombosis following splenectomy using real-time and Doppler sonography].

Superior mesenteric vein thrombosis after splenectomy is very rare. In the case described of a patient presenting with acute abdominal pain the diagnosis was made primarily by real-time and Doppler ultrasonography. This reduced the time elapsing before it was recognized that angiography and subsequent thrombectomy were indicated.
