Aneurysm of the Portal Vein and Portal Hypertension

Extrahepatic Portal Vein Aneurysm

Portal vein aneurysms are rare vascular abnormalities, many of which are incidentally discovered on routine imaging studies. The etiology of portal venous aneurysms is poorly understood, and the management of these lesions is debatable. We report the case of a 61-year-old woman with extrahepatic portal vein aneurysm. We review the nature and significance of this abnormality and discuss appropri...

Intrahepatic ramifications of the portal vein in the horse

The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...

Symptomatic Presentation of Intrahepatic Portal Vein Aneurysm

A 52-year-old female without comorbidities presented with dull, aching pain in the right upper quadrant associated with nausea, but not fever, jaundice, anorexia, or abdominal distension. Examination showed tachycardia and mild tenderness in the right upper quadrant. Investigations revealed a normal hemogram with preserved liver function, renal function, and normal pancreatic enzyme levels. Abd...

association between portal vein color doppler findings and the severity of disease in cirrhotic patients with portal hypertension

Portal vein prostacyclin activity in experimental portal hypertension in rats.

1. Portal hypertension was produced experimentally in rats by partial ligation of the portal vein. 2. One week later portal veins of these animals were shown to release significantly greater amounts of prostacyclin than control animals. 3. It is postulated that if this response occurs in man, local vasodilatation and inhibition of platelet aggregation may be exacerbatory factors in the severity...
