Portal Hypertension Imaging Diagnosis and Endovascular Management: A Clinical Overview
"Portal hypertension—characterized by an elevated hepatic venous pressure gradient exceeding 5 mmHg—is a critical syndrome driven primarily by increased intrahepatic vascular resistance and hyperdynamic splanchnic circulation. Imaging diagnostics, including Doppler ultrasonography, computed tomography, and magnetic resonance imaging, provide essential visualization of vascular architecture, portosystemic collaterals, and parenchymal changes. Concurrently, endovascular interventions such as transjugular intrahepatic portosystemic shunts (TIPS) and balloon-occluded retrograde transvenous obliteration (BRTO) offer targeted, minimally invasive the..."
