Abstract
Portal hypertension is a major complication of post-hepatitis cirrhosis. Hemodynamically-directed approaches to control portal hypertension have attempted to lower either the resistance or the portal arterial inflow that is considered a major factor for aggravating portal hypertension and development of collaterals.
Color duplex is an accurate and non-invasive tool for the hemodynamic studies. Nowadays, it gives the opportunity for not only non-invasive diagnostic assessment but also for serial follow up of the hemodynamic effects of various therapeutic modalities of portal hypertension using its unique indices. These indices include congestion index of portal vein, pulsatility and resistive indices of hepatic artery and liver vascular index as well as the flow volume calculation.
PSE is a relatively new interventional treatment modality that is based on ablation of 60:80% of the splenic arterial blood flow. It was used for the treatment of hypersplenism in cirrhosis. It was somewhat difficult and the technical success was 87.5%. The main cause of failure was the inability to catheterize the distal segment of the splenic artery because of being hypertrophied and tortuous in cirrhotic patients.
