ABSTRACT
To report the success of treatment with low-molecular-weight heparins [LMWHs] in a case of nephrotic syndrome complicated by mesenteric vein thrombosis [MVT] and portal vein thrombosis [PVT]. A 53-year-old man with nephrotic syndrome developed persistent mild abdominal pain for 3 days. Hepatic-portal venous system thrombosis of nephrotic syndrome was suspected due to new-onset superficial vein engorgement of the abdomen without liver cirrhosis. Abdominal computed tomography revealed MVT concomitant with PVT. He was successfully treated with LMWH without thrombolytic therapy. After discharge on day 9, he received continuous anticoagulation by LWMH on an outpatient basis at the nephrology clinic. Venous thromboembolic events or proteinuria did not recur within the 6-month follow-up. This report showed a case of MVT concomitant with PVT, a critical complication of nephrotic syndrome that was diagnosed in time and successfully treated with LMWH. A high index of clinical suspicion and timely management are crucial to tackle thrombotic complications in nephrotic syndrome
