  • Portosystemic collateral pathways - Radiopaedia. org
    Portosystemic collateral pathways , also called spontaneous portosystemic shunts or varices, develop spontaneously via dilatation of pre-existing anastomoses between the portal and systemic venous systems
  • Portosystemic Shunts: Should We Pay Closer Attention with Cross . . .
    When the HVPG exceeds 10 mmHg, patients develop portosystemic collateral vessels, that is SPSS, that bypass portal blood flow around the liver (2) Many forms of SPSS can develop, leading to shunting of blood away from the liver, which otherwise detoxifies blood arriving from the gut
  • Portosystemic collateral pathways on portal hypertension: a . . . - EPOS™
    Portal hypertension generates a difficulty in the outflow of blood from portal to hepatic venous system To bypass this blockage, a portal venous network rearrange takes place, dilating preexistent vessels and also activating angiogenesis, developing portosystemic collateral pathways
  • CASE SERIES: PORTOSYSTEMIC COLLATERALS
    Portosystemic collaterals are abnormal communications between the portal system and the systemic circulation, and such shunts can be congenital or acquired
  • Understanding Portosystemic Collateral Anatomy | CoLab
    This article reviews the clinical presentations associated with portosystemic shunts, explores the anatomical variants and altered flow dynamics, and discusses the latest endovascular treatment strategies to optimize patient outcomes
  • Portosystemic collaterals
    This article aims to describe the various portosystemic collateral pathways in patients with portal hypertension on multidetector row computed tomography and their clinical importance, with special emphasis on the uncommon collaterals
  • Portal-Systemic Collaterals: Anatomy and Clinical Implications - Springer
    As portal venous pressure increases, portal-systemic collateral routes develop, and part of the blood that normally goes to the liver reaches the systemic circulation without coming in contact with hepatocytes
  • Characterization of uncommon portosystemic collateral circulations in . . .
    Portosystemic uncommon collateral circu-lation (UCC) was detected, characterized and evaluated by a combination of spiral computed tomography angiography, three-dimensional imaging angiography and electronic gastroscopy in patients diagnosed with hepatic cirrhosis
