Portal vein diameter in cirrhotic and non cirrhotic patients. A sonographic comparison

Research Paper (postgraduate) from the year 2022 in the subject Medicine - Internal Medicine, grade: A+, University of Lahore (University of Lahore), course: Msc Ultrasound, language: English, abstract: This publication aims to compare the portal vein diameter in cirrhotic and non-cirrhotic patients through ultrasound. Liver cirrhosis is a clinical condition in which the normal liver parenchyma is replaced with fibrosis in such a situation it becomes difficult for blood to easily pass through the Portohepatic venous system.

Therefore, the portal vein becomes engorged and increases in diameter, while blood flow velocity reduces. Portal hypertension is clearly-defined as the rise of portal venous pressure, largely due to cirrhosis, which leads to increased hepatic vascular resistance and engorgement of the blood in the portal venous system.

This disease may result in an array of disorders, like that the development of collateral vessels for returning of the blood to the right atrium with the potentiality for intestinal bleeding, development of ascites, encephalopathy, and formation of a 11 hyper-dynamic circulation involving peripheral and splanchnic vessels, related with the malfunction of kidneys, the heart, the lungs, and the brain.
