BACKGROUND: Portal vein thrombosis (PVT) is complex and risk factors include local precipitating factors and acquired and inherited factors. It occurs secondary to abdominal malignancy, infection or surgical intervention. PVT is commonly forgotten as a possible cause of abdominal pain. The clinical picture may vary but abdominal pain and low grade fever are the most characteristic picture. METHODS: A 58-year-old male patient was admitted to our hospital complaining of abdominal pain for three days. CT scan revealed an edematous area around the portal vein. Doppler ultrasonography showed evidence of a portal vein thrombosis. RESULTS: PVT can be diagnosed with CT and Doppler ultrasonography. Fresh thrombus can be undetected by sonography because of the low echogenity but can be recognised by color Doppler ultrasonography. Treatment ranges from observation and bowel rest to surgical resection of bowel. CONCLUSIONS: When we suspect a case of PVT, it should be treated at an early stage to prevent being lost in a diagnostic dilemma. The immediate use of anticoagulant could be important in preventing serious consequences of PVT.

The level of urinary FPA was assayed by high per formance liquid chromatography (HPLC ) in 42 normal controls, 57 cases of chronic glomeru-lonephritis, including 24 with normal renal function, 12 with renal insufficiency and 21 with uremia. Their levels were 24. 40± 10. 30 μg/L, 26. 99±5.77 μg/L,38. 81±6. 28 μg/L, 79. 74± 18. 76 μg/L, respectively. The level of urinary FPA in renal insufficiency function group was significantly higher than those of the con-trol group and normal renal function group (P<0.01). The patients with uremia presented dramatically higher level of urinary FPA than those in the renal insufficiency group (P<0.01). A positive correlation was found between the level of urinary FPA and the blood creatine (r= 0. 9120, P<0. 01 ). It was suggested that a hypercoagulable state existed in the patients with chronic nephritis with renal failure, in which the severity was closely related with the occurrence and development of the disease. The urinary FPA could serve as a good indicator for renal function.

Human immunodeficiency virus(HIV) may result in devastating multi-organ complications, including cirrhosis. Consequently, liver transplantation is often required for these patients. We report a case of a 43-year-old female with cryptogenic cirrhosis and HIV on highly active antiretroviral therapy, presenting for non-related living donor liver transplantation. The intraoperative course was complicated by hepatic artery and portal vein thrombosis, requiring thrombectomy. On postoperative day-3, the patient required retransplantation with a cadaveric donor organ due to primary graft failure.
