Approximately one in six patients with portal hypertension who develop varices at sites of portosystemic venous collaterals has gastric varices due to hepatofugal flow into the gastric veins. Bleeding from gastric varices, though less common, has a higher mortality and morbidity compared to bleeding esophageal varices, which are easier to manage endoscopically. The efferent channel for gastric varices is mostly the gastrorenal shunt (GRS) which opens into the left renal vein. Balloon-occluded transvenous obliteration (BRTO) involves accessing the GRS with an aim to temporarily occlude its outflow using a balloon catheter and at the same time injecting sclerosant mixture within the varix so as to cause its thrombosis and thereby obliteration...

Portal Vein Thrombosis (PVT) is caused by various thrombophilic states. PVT secondary to underlying vasculitis especially Churg-Strauss disease is among the rarest presentation. Here, we report a case of peripheral eosinophilia, eosinophilic ascitis and venous thrombosis involving portal vein and superior mesenteric vein diagnosed as Churg-Strauss Syndrome (CSS). He was managed with steroids and anticoagulants. Following initiation of steroids, eosinophilia and eosinophilic ascitis improved.

In acute portal vein thrombosis (APVT) unrelated to cirrhosis, anticoagulant therapy is classically started with low molecular weight heparin or vitamin K antagonists. New direct-acting oral anticoagulants (DOACs) are used in the treatment of venous thrombosis outside the splanchnic vascular bed, but not in the latter. We report a young female with APVT occurring in a non-cirrhotic liver linked to heterozygosity of factor V-Leiden and prothrombin G20210A gene mutations. Rivaroxaban was started, with total recanalization of the left and partial recanalization of the right portal vein branches, without complications...

The hallmark manifestations of Cushing's syndrome (CS) are well known, but hypercoagulability is perhaps least recognized. Patients with CS are at increased risk of both spontaneous and postoperative thromboembolism, with the significant majority of events occurring in the lower extremity and pulmonary venous circulations. We present a case of portal vein thrombosis (PVT) occurring in the setting of newly diagnosed CS due to a left adrenal adenoma. Factor VIII activity was approximately 2.5-fold elevated, a known mechanism by which hypercortisolemia predisposes to venous thrombosis...

Melioidosis, caused by Burkholderia pseudomallei, is a common infectious disease in tropical regions. The author reports a case of melioidosis with a rare manifestation of portal vein thrombosis and cavernous transformation of the portal vein. Melioidosis should be considered a differential diagnosis in patients with underlying risk factors who present with multiple liver abscesses; moreover, portal vein thrombosis can be a potential complication. Computed tomography is the modality of choice to demonstrate venous thrombosis in various organs...

Foodborne illnesses are common and are usually considered as part of the differential diagnosis when a patient presents with gastrointestinal symptoms including nausea, vomiting, abdominal pain, diarrhea and fever. The majority of foodborne illness is transient and self-limited, while life threatening complications are rare. Here, we describe a case of a patient presenting with inflammatory diarrhea after consumption of undercooked seafood. She developed mesenteric and portal venous thrombosis and small bowel infarction requiring surgical intervention and resection of gangrenous small bowel...

The liver has a complex vascular supply, which involves the inflow of oxygenated blood through the hepatic artery (systemic circulation) and deoxygenated blood through the portal vein (portal circulation), as well as the outflow of deoxygenated blood through the hepatic veins to the inferior vena cava. A spectrum of vascular variants can involve the liver. Some of these variants may result in areas of enhancement that can mimic more serious pathologic conditions. In this article, the authors discuss a spectrum of variants and pathologic conditions that may involve the liver vasculature...

Venous thrombosis of pancreas transplant allografts often leads to graft loss. Its worrisome complication and difficult to treat, forming the most common nonimmunological cause of graft loss. Multiple risk factors have been implicated in the development of venous thrombosis of pancreas transplant. Color Doppler ultrasonography (CDUS) enables early diagnosis of venous thrombosis, thus increasing the possibility of graft-rescue treatments. Endovascular management of pancreatic transplant vascular complications are scant and in the form of case reports...

Live donors should be the priority of transplant professionals to prevent surgery-related morbidity and mortality during living-donor liver transplantation. Portal vein thrombosis after donor hepatectomy is an important complication which can be prevented by careful preoperative as well as perioperative evaluation. If portal vein thrombus occurs after donor hepatectomy, anticoagulation and surgical thrombectomy and even portal vein reconstruction should be kept in mind. Cadaveric venous patches can be used for the reconstruction of narrowed and angulated portal veins...

Congenital extrahepatic portosystemic shunt (Abernethy malformation) is a rare condition characterized by developmental abnormalities of the portal venous system resulting in the diversion of the portal blood from the liver to the systemic venous system through a complete or partial shunt of the portomesenteric blood. We report the case of an 18 year-old female examined for abdominal pain, presenting cholestasis syndrome and an elevated serum aspartate aminotransferase level. Liver ultrasound examination revealed the absence of the portal vein with a complete extrahepatic shunt of the portal blood, multiple focal liver lesions, and multiple associated vascular anomalies...

Filippo Leonardi, Nicola De Maria, Erica Villa
The liver plays a crucial role in coagulation cascade. Global hemostatic process is profoundly influenced by the presence of liver disease and its complications. Patients with cirrhosis have impaired synthesis of most of the factors involved in coagulation and fibrinolysis process due to a reduced liver function and altered platelet count secondary to portal hypertension. Altered routine tests and thrombocytopenia were considered in the past as associated with increased risk of bleeding. These concepts explain both the routine use of plasma and/or platelets transfusion in patients with liver cirrhosis, especially before invasive procedures, and why these patients were considered "auto-anticoagulated"...

Portomesenteric venous thrombosis (PMVT) is a rare but well-reported complication following laparoscopic surgery. We present three cases of PMVT following laparoscopic surgery. Our first case is a 71-year-old morbidly obese woman admitted for elective laparoscopic giant hiatus hernia (LGHH) repair. Post-operatively, she developed multi-organ dysfunction and computed tomography scan revealed portal venous gas and extensive small bowel infarct. The second patient is a 51-year-old man with known previous deep venous thrombosis who also had elective LGHH repair...

For transplant surgeons, end-stage liver disease with portal venous thrombosis and a previous splenorenal shunt (SRS) is a significant challenge during liver transplantation. Thrombosis of the portal vein can be corrected by surgical interventions, such as portal venous thrombectomy or surgical removal of the thrombosed portal vein. Even also placement of a graft between the mesenteric vein and the graft portal vein can be performed. If these maneuvers fail, a renoportal anastomosis (RPA) can be performed to achieve adequate graft inflow...
