Introduction. Portal vein (PV) thrombosis (PVT) is a partial or a complete
obstruction of blood flow as a result of a thrombus mass in the lumen of PV.
In the acute phase, the symptoms are unspecific such as right upper quadrant
pain, nausea and fever. Diversity of subacute and chronic symptoms are
associated with complications related to PVT and portal hypertension. Case
report. We are presenting a case of a 50-year-old female who was admitted in
hospital due to acute abdominal cramping pain. The pain lasted for 15 to 20
minutes, and was followed by defecation of normal stool and haematochezia in
three occasions. The abdominal pain returned in several hours, again
followed by haematochezia and tenesmuses every 10 minutes. After admission a
colonoscopy was performed that determined vulnerable, erythematous mucosa of
the colon with contact bleeding from lienal flexure to rectosigmoid
junction. During the colonoscopy, a biopsy was performed. A computer
tomography (CT) scan revealed partial PVT, thrombosis of intrahepatic
branches of PV and thrombosis of the inferior mesenteric vein. After
conservative treatment with low molecular weight heparin (LWMH), and other
supportive measures the digestive bleeding ceased, and defecation became
normal. During one month follow up a patient has had no complications and
control CT scan revealed normal PV flow without thrombosis. Conclusion:
Although is a rare, a non-malignant and non-cirrhotic PVT in differential
diagnosis should not be neglected because timely and vigilant therapy with
LWMH can lead to complete resolution without serious complication.
