title: Intraoperative US diagnosis of pylephlebitis (portal vein thrombosis) as a complication of appendicitis: a case report.
abstract: We report a case of infectious thrombosis of the superior mesenteric vein (pylephlebitis) that was suspected preoperatively with computed tomography and confirmed at intraoperative ultrasonography as confined to the extrahepatic portal vein and superior mesenteric vein. Intraoperative ultrasonography revealed intraluminal echogenic thrombus material in the dilated superior mesenteric and extrahepatic portal veins, slightly dilated open splenic vein, and numerous venous collaterals in the hepatoduodenal ligament. When preoperative imaging studies are inconclusive, intraoperative sonography can confirm the correct diagnosis of pylephlebitis and may give valuable information about the extent of the thrombosis.
