The organizing idea: the hepatic venous pressure gradient is the hemodynamic gold standard, and liver stiffness plus platelets give the noninvasive translation that now drives beta-blocker and screening decisions. Screening thresholds, primary prophylaxis, and the acute variceal hemorrhage bundle all key off the same physiology, with the restrictive transfusion target, mandatory ceftriaxone, and the early-TIPS decision as the cirrhosis-specific layers. It closes on gastric varices, portal hypertensive gastropathy, and GAVE, where anatomy and drainage pick the therapy, not appearance.\n \nTopics covered\n\nPortal hypertension hemodynamics and HVPG thresholds\nBeta-blocker response and presinusoidal versus postsinusoidal causes\nNoninvasive CSPH detection and the rule of five\nVariceal screening and surveillance intervals\nPrimary prophylaxis: carvedilol versus band ligation\nThe acute variceal hemorrhage bundle\nEarly TIPS during the index admission\nGastric varices, portal hypertensive gastropathy, and GAVE\n \n \nKey decisions\n\nAn HVPG over five defines portal hypertension, ten or higher defines clinically significant portal hypertension and identifies who will develop varices and decompensation, and over twelve marks the variceal bleeding threshold; a beta-blocker responder drops the gradient more than a fifth or below twelve.\nBy the rule of five, a liver stiffness of twenty-five kilopascals or higher rules in clinically significant portal hypertension while stiffness of fifteen or lower with platelets of a hundred fifty thousand or higher rules it out; defer screening endoscopy when stiffness is under twenty and platelets over a hundred fifty thousand.\nIn compensated cirrhosis with clinically significant portal hypertension, a beta-blocker reduces first decompensation even without high-risk...","thumbnail_url":"https://img.transistorcdn.com/-FuAdDBcPDLhEoUmroZKtOBRvuBn_FHPpYlh41hOnU4/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9iNzlh/ZTU4Y2MzNWExMjQ5/MjA5OWMwMmI3ZTk5/NGFiZS5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
