Portal Cavernoma during Pregnancy

Abstract EN

Portal vein thrombosis (PVT) is characterized by the obstruction of the portal venous system.

The venous obstruction can be partial or complete and it is caused by thrombogenic conditions (acquired or hereditary) or nonthrombotic factors.

The acquired conditions include abdominal inflammation, infections, surgery, myeloproliferative disorders, obesity, oral contraceptive intake, pregnancy, and postpartum period.

Occasionally, it is not possible to recognize any overt cause of PVT.

During pregnancy there is an increased venous thromboembolism risk mainly in the systemic venous system and the PVT can occur, but there are no data about its exact prevalence, etiology, and outcome.

The portal cavernoma is the cavernomatous transformation of the portal vein.

It is a consequence of chronic PVT and occurs when myriads of collateral channels develop to bypass the occlusion.

The clinical presentation includes hematemesis due to variceal bleeding, ascites or anaemia, and splenomegaly.

The cavernous transformation of the portal vein is easily diagnosed by sonography.

We report our case of a 32-year-old, gravida 3 para 2, pregnant woman admitted to our hospital at 13 weeks and 1 day of gestation, clinically asymptomatic.

Laboratory test, ultrasound, and endoscopic evaluation were negative.

After a detailed counseling, the patient decided on termination of pregnancy at 15 weeks and 1 day of gestation.
