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[ ]. A unique clonal JAK2 mutation leading cacernoma constitutive signalling causes polycythaemia vera.

In non-cirrhotic and non-neoplastic patients, PVT has generally good outcome; exitus for gastrointestinal bleeding is uncommon[ 65 acvernoma, 9697 ].

Deficiency of natural anticoagulant proteins C, S, and antithrombin in portal vein thrombosis: Opinions regarding therapeutic options in chronic PVT are more controversial and significantly variable.

Incidentally, US is less reliable in determining the extension of the thrombus to the mesenteric circulation[ 79 ]. If no local risk factor is found, the presence of a thrombophilic disorder must be investigated.

It seems to be effective in resolving portal biliopathy, ascites, and portal hypertension, but it is not feasible if portal vein is not catheterizable or a cavernomatous vein cannot be dilated[ – ]. This vascular neo-formation begins in a few poeta after portal vein obstruction, and finalizes within 3 porfa 5 wk[ 67 ].

Today, thanks to the availability of more sensitive and less invasive imaging, together with the existence of curative or palliative procedures, PVT is routinely investigated and recognized without any difficulty[ 14 – 16 ].


Portal vein thrombosis: Insight into physiopathology, diagnosis, and treatment

Instead, a rapid and complete obstruction of the portal or mesenteric vein, without the involvement of the mesenteric venous arches, induces only intestinal congestion; the veba feature is a diffuse thickening of the intestinal wall, visible even without alterations in contrast enhancement.

If acute PVT is suspected, computed tomography CT scan, before and after injection of vascular contrast agent, should be obtained for early confirmation of diagnosis.

In this review, we discuss the features of PVT, pointing out new insights into clinical, diagnostic, and therapeutic issues, making an overview of current beliefs regarding patient outcome and, finally, reporting controversies about the correct management of PVT in the setting of liver transplantation. Furthermore, hypersplenism and, consequently, pancytopenia, are commonly present in chronic PVT[ 1 ]; however, if one branch of the portal vein is preserved and the portal pressure is quite normal, vdna may even be absent.

Current outcome of portal vein thrombosis in adults: The role of protein S PS and antithrombin III AT deficiency in PVT etiology has not yet been confirmed, and it is difficult to evaluate the influence venx anticoagulation therapy on the impairment in liver function.

Furthermore, patients with an obstruction of more than half of the portal vein, extended or not to the superior mesenteric vein, seem to have increased risk of severe peri-operative complications, higher mortality, and decreased long-term survival[ 85, ].

Portal vein thrombosis: Insight into physiopathology, diagnosis, and treatment

Although spontaneous resolution of PVT has been reported in the literature[], a specific therapeutic management is mandatory to resolve portal vein obstruction and avoid serious complications. Eversion thromboendovenectomy in organized portal vein thrombosis during liver transplantation. Lai L, Brugge WR. Portal vein thrombosis in patients undergoing orthotopic liver transplantation: Acute mesenteric venous thrombosis: Vascular liver disorders II: Other modalities of treatment should be adopted only in case of partial or absent PVT resolution[ 12].


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

Furthermore, the presence of anticardiolipin antibodies is quite frequent in patients with chronic liver disease; a transient positivity is often reported after infections, suggesting a relationship between microorganisms i. MR, CT, and ultrasonography of splanchnic venous thrombosis. In addition, cavrenoma circulation develops rapidly from pre-existing veins in the porta hepatis within 2 to 3 d after the onset of acute thrombosis, particularly in the gallbladder wall[ 619495 ].

Epub ahead of print. Clinical and laboratory evaluation, as well as imaging, might be useful; the degree of the obstruction complete or partial, limited or extensive should dde investigated. Condat B, Valla D.

Despite the high incidence of side effects, thrombolysis should be considered when initial anticoagulant therapy fails, even if there is no consistent evidence concerning in which conditions it should be preferred to anticoagulation[ ].

Liver transplantation in adults. J Am Coll Surg. The incidence among cirrhotic patients is still unknown, but recent data suggest a prevalence of about 0.
