Among the possible venous thromboembolic events in nephrotic syndrome, renal vein thrombosis and pulmonary embolism are common, while portal vein thrombosis (PVT) is rare. This report describes a 26-year-old man with histologically proven minimal change disease (MCD) complicated by PVT. The patient presented with epigastric pain and edema. He had been diagnosed with MCD five months earlier and achieved complete remission with corticosteroids, which were discontinued one month before the visit. Full-blown relapsing nephrotic syndrome was evident on laboratory and clinical findings, and an abdominal computed tomography revealed PVT. He immediately received immunosuppressants and anticoagulation therapy. An eight-week treatment resulted in complete remission, and a follow-up abdominal ultrasonography showed disappearance of PVT. In conclusion, PVT is rare and may not be easily diagnosed in patients with nephrotic syndrome suffering from abdominal pain. Early recognition of this rare complication and prompt immunosuppression and anticoagulation therapy are encouraged to avoid a fatal outcome.
Splanchnic vein thrombosis arising from complications of acute pancreatitis is very rare. It usually occurs as a form of portal, splenic and superior mesenteric vein thrombosis, either in combination or separately. It could develop portal hypertension, bowel ischemia and gastrointestinal variceal bleeding. Treatment of splanchnic vein thrombosis includes anticoagulants, thrombolysis, insertion of shunts, bypass surgery and liver transplantation. In some cases, anticoagulation therapy may be considered to prevent complications. However, the standard protocol for anticoagulation in splanchnic vein thrombosis has not been determined yet. We report a case of 43-year-old man who had portal and splenic vein thrombosis in acute pancreatitis. The patient was successfully treated with oral anticoagulants following low molecular weight heparin therapy.

Antiphospholipid antibody syndrome (APS) is characterized by raised levels of antiphospholipid antibodies (aPL), in association with thrombosis, recurrent fetal loss, and thrombocytopenia. Development of APS is related with idiopathic origin, autoimmune disease, malignancy and, on rare occasions, infection. However, in secondary APS combined with bacterial infections, aPL is usually shown with low titer and rarely associated with thrombotic events. A 52-year-old male was admitted due to pneumonia and multiple hepatosplenic abscesses. He had been treated with proper antibiotics, but he presented ascites and sudden variceal bleeding because of portal vein thrombosis. The bleeding was controlled by endoscopic variceal ligation. Acute portal vein thrombosis was successfully managed by low molecular weight heparin and hepatosplenic abscesses were completely resolved by antibiotics. This case suggests that systemic bacterial infection in immunocompetent patients possibly develops into secondary APS.
