Indeed, in cirrhotic patients it is hard to distinguish between congenital and acquired deficiencies of natural coagulants and their role in PVT pathogenesis, because if liver function is impaired, levels of coagulation inhibitors, as well as those of pro-coagulation factors, are often decreased[ 27 ].

Other treatments Thrombolytic therapy, given either into the caverboma venous circulation, the superior mesenteric artery, or the portal vein via a transjugular or transhepatic route, is also effective to provide recanalization in acute PVT[ – ]. The occlusion of the portal vein is always more scarring than the thrombosis of the hepatic artery and may be seriously threatening for both graft and patient survival[ ].


CT is also useful for the identification of the possible cause of the thrombosis or potential complications, such as bowel pora and perforation[ 22 ]. Nowadays, anticoagulant therapy is the best way to obtain portal vein recanalization; however, there is no consensus on its application.

Finally, the role of oral contraceptives, steroids, and pregnancy is still less clear[ 45 – 47 ]. Consensus on extra-hepatic portal vein obstruction.

Intestinal congestion and ischemia are typical manifestations of acute PVT; abdominal pain or distention, diarrhea, rectal bleeding, nausea, vomiting, anorexia, fever, lactacidosis, splenomegaly and sepsis might vsna variably present[ 6364 ].

In addition, in hypoperfused areas, hepatic enhancement appears increased during the arterial phase and decreased during the portal phase. Biliary obstruction caused by portal cavernoma: Valla DC, Condat B. Furthermore, in the diagnostic iter, the identification of ls local or systemic trigger factors is of primary importance however, occasionally no single factor is discernable. Determining prognosis and creating clinical decision rules. Recently, a panel of experts recommended the application of anticoagulant therapy only in PVT patients with a proven thrombophilic disorder or familial history of venous thrombosis[], thereby obtaining an improvement in survival and reduction in risk of gastrointestinal bleeding[].

Systemic risk factors, like MPD or other prothrombotic disorders, seem not to affect short-term survival[ 99 ].

This article has been cited by other articles in PMC. Caveenoma, PVT seems more frequent than expected: However, efficacy is significantly lower and mortality increased in patients who undergo thrombolysis, if compared to conservative treatment[ 59, ]. Webb LJ, Sherlock S. Incidentally, a pragmatic approach, such as endoscopical eradication of varices prior to commencement of anticoagulation, should be reasonable[ 79 ].

Unfortunately, in practice, this policy is not applicable without difficulty. Management of portal vein thrombosis in liver transplantation: National Center for Biotechnology InformationU. Sobhonslidsuk A, Reddy KR. Other less common PVT local causes are adenopathy, systemic inflammatory response syndrome, and surgical traumas to the portal venous system, such as portosystemic shunting, splenectomy, liver transplantation, ablative therapy for HCC, and fine needle aspiration of abdominal masses[ 1 ].


Complete thrombosis of the portal vein trunk ultrasonography ; B, C: Thus, for all these reasons and the good results reported in literature, today PVT has no longer to be considered a contraindication but only a disadvantage and, in some cases, might present a possible indication to liver transplantation[,].

Moreover, a homozygous methylene tetrahydrofolate reductase MTHFR gene mutation might be associated with PVT development alone or, if heterozygote, in the presence of other cofactors[ 1335 – 39 ].
