ABSTRACT
Portal hypertension is defined as pathological increase in portal venous pressure. Increase in portal venous pressure can be caused by increased resistance to blood flow either at the level of the portal vein (pre-hepatic), hepatic sinusoids(hepatic) or hepatovenous outflow (post-hepatic). This results in formation of portosystemic collateral pathways between the splanchnic circulation and the systemic circulation. Isolated gastric and esophagogastric collaterals are another important collateral pathways to be mentioned, because they may cause massive gastrointestinal hemorrhage if goes untreated. These pathways are numerous, widespread and varied in appearance. Knowledge of these common and less-common portosystemic collateral pathways on CT /MRI at each anatomic site is important implication for clinicians and interventional radiologists to plan their further management.
