ABSTRACT Portal vein thrombosis is the thrombotic occlusion of the extrahepatic portal system, which can propagate towards the vena caval system. Although rare, it occurs primarily in those with cirrhosis, intra-abdominal infections, malignancy, or hypercoagulable disorders. This report describes the first reported case of a soldier within special operations without identifiable risk factors who was found to have a completely occlusive portal vein thrombosis after approximately 10 days of insidious abdominal pain. This case emphasizes the importance of considering this rare but dangerous patho

Polycythemia vera is a medical condition characterized by raised hematocrit. Owing to increased viscosity, the blood flow in the vessels become sluggish leading to the clinical features of polycythemia such as headache, blurring of vision, red skin, dizziness, raised blood pressure, itching and more serious medical events like vaso occlusion, thrombosis and strokes. In this case report, polycythemia vera presenting unusually with heamatemesis, melena and abdominal distension.

Due to endothelial impairment, high-dose lithium may produce an occlusive-like syndrome, comparable to permanent occlusion of major vessel-induced syndromes in rats; intracranial, portal, and caval hypertension, and aortal hypotension; multi-organ dysfunction syndrome; brain, heart, lung, liver, kidney, and gastrointestinal lesions; arterial and venous thrombosis; and tissue oxidative stress. Stable gastric pentadecapeptide BPC 157 may be a means of therapy via activating loops (bypassing vessel occlusion) and counteracting major occlusion syndromes. Recently, BPC 157 counteracted the lithium

As liver tumours receive some of their blood supply from the portal vein, we wanted to illustrate the influence of portal blood flow in combination with dearterialization in the treatment of liver tumours. Forty male, inbred Wistar/Furth rats with an adenocarcinoma transplanted to the liver were treated with various inflow occlusions repeated daily for 5 days. Deviation of the portal blood flow alone with an end-side porto-caval shunt did not alter the tumour growth (p = 0.089). Thirty min of repeat dearterializations was potentiated by portal deviation so that tumour growth was delayed (p = 0

We evaluated involvement of adrenergic receptors in the responses of the hepatic vasculature to reduction either of portal venous flow or hepatic arterial inflow. Portal vein occlusion caused an increase in hepatic arterial blood flow (HAF) and decreases in hepatic arterial pressure (HAP) and hepatic arterial vascular resistance (HAR) in the intact group. After pretreatment with either yohimbine or prazosin, but not propranolol, occlusion of the portal vein produced a greater decrease in HAP as compared with that in the intact group.

There are two afferent (hepatic artery, portal vein) and one efferent (hepatic veins) systems responsible for the unique circulation of the liver. Given this special form of vasculature, acute, isolated (i.e. involving selectively one particular vessel) vascular occlusions may lead to different, however still life threatening conditions. Hence, it is essential to recognize these anomalies in order to preserve the healthy state of both the liver and the patient’s lives.

AbstractInterventional radiology's role in the management of portal hypertension in the pediatric population differs from the management of adult portal hypertension. In the pediatric population, portal hypertension is frequently secondary to thrombosis and cavernous transformation of the extrahepatic portion of the portal vein. Transjugular intrahepatic portosystemic shunt can be utilized to manage portal hypertension in children with intrinsic liver disease that results in cirrhosis and portal hypertension, and is often used as a bridge to transplant. While technically feasible in extrahepat

Background: Patients with splenic vein occlusion may present a diagnostic problem when the location, morphology, and cause of the obstructive lesion and the associated collateral veins cannot be clearly defined by standard diagnostic imaging modalities such as computed tomography, magnetic resonance venography, or indirect splenoportography (arterial portography). Purpose: To evaluate the safety and effectiveness of carbon dioxide (CO2) wedged arterial splenoportography for definitive investigation of splenic vein occlusion. Material and Methods: Following unsuccessful diagnosis with computed

Gastric pentadecapeptide BPC 157 therapy counteracts multiple organ dysfunction syndrome in rats, which have permanent occlusion of the superior mesenteric artery close to the abdominal aorta. Previously, when confronted with major vessel occlusion, its effect would rapidly activate collateral vessel pathways and resolve major venous occlusion syndromes (Pringle maneuver ischemia, reperfusion, Budd–Chiari syndrome) in rats. This would overwhelm superior mesenteric artery permanent occlusion, and result in local, peripheral, and central disturbances. Methods: Assessments, for 30 min (gross reco

A portable apparatus for performing repeated, brief coronary artery occlusions automatically in long-term chronic studies involving dogs and larger animals is described. The battery-operated, back-pack-carried device uses a motorized syringe driven by a digital-programmable timing circuit to inflate a coronary artery occluder for durations of 10 s to 3 min at intervals from 14 s to 16 h. A single battery charge produces 450 occlusions. The generated pressure is adjustable to 1,000 mmHg maximum. A separate fail-safe circuit monitors system operation to open a pressure-relief valve if occlusions

Portal biliopathy refers to biliary tree abnormalities in patients with peribiliary collateral vessels and non-neoplastic extrahepatic portal vein occlusion. These biliary abnormalities are caused by vascular compression and ischemic damage of the biliary tree, which can result in bile duct compression, stenosis, fibrotic strictures, bile duct dilation, and thickening of the bile duct wall. Portal biliopathy is difficult to distinguish from cholangiocarcinoma, IgG4-related disease, and sclerosing cholangitis. Although most patients are asymptomatic, portal biliopathy can lead to serious compli

Transjugular intrahepatic portosystemic shunt (TIPS) occlusion is a common occurrence that can be managed based on the nature and acuity of shunt failure. Arterioportal fistulas (APFs) are rare communications between portal venous and systemic arterial vasculature that can present with symptomatic portal hypertension. In this case, we describe the management of a patient with variceal bleeding due to TIPS dysfunction complicated by the presence of an APF.
