栓塞是腎病症候群的併發症之一，目前的文獻報告指出該栓塞可發生於許多的血管，包括腎動脈，腎靜脈，股動脈，膝後窩動脈及臂動脈等。門靜脈栓塞也是其中之一，目前僅有五個病例報告。本文報告一例27歲有腎病症候群病史的男性，因間歇性腹痛來急診求診。不幸的，這個病人最後由於缺血性腸炎不幸過世。當腎病症候群的病人因腹痛來到急診時，急診的醫師應將其併發症列入鑑別診斷，特別是栓塞的併發症。在這種病人中，電腦斷層檢查是診斷工具的首選，而且應儘速安排。

Thromboembolism is known as a major complication of nephrotic syndrome. Thromboembolism can occur in many vessels, including the renal vein, and renal, femoral, brachial and popliteal arteries. Portal vein thrombosis is a rare complication of nephrotic syndrome, and there are only 5 case reports of this condition overall. Herein, we present a 27-year-old man with portal vein thrombosis with nephrotic syndrome who came to our emergency department (ED) due to intermittent abdominal pain. Unfortunately, the patient died due to ischemic bowel. If a patient with nephrotic syndrome presents in the ED with abdominal pain, ED physicians should keep complications of nephrotic syndrome in mind, especially thromboembolism. Computed tomography (CT) is an appropriate early diagnostic tool, and should be done immediately.
