Pharmacological Regimens, Surgical Stenting, and Endoscopic Interventions
Managing elevated portal venous pressure requires a multi-faceted approach combining systemic drug regimens, endoscopic procedures, and radiological shunt placements depending on disease severity and acute complication risks.
Treatments across primary clinical classes include:
-
Non-Selective Beta-Blockers (NSBBs): Agents like carvedilol and propranolol lower portal pressure by reducing cardiac output ($\beta_1$-blockade) and inducing splanchnic vasoconstriction ($\beta_2$-blockade).
-
Vasoactive Peptides: Somatostatin analogs (octreotide) and vasopressin analogs (terlipressin) cause acute splanchnic vasoconstriction during active variceal hemorrhage episodes.
-
Surgical & Interventional Procedures: Transjugular Intrahepatic Portosystemic Shunts (TIPS) create a low-resistance pathway between the portal vein and hepatic vein to decompress portal pressure directly.
-
Endoscopic Modalities: Endoscopic variceal ligation (EVL) and cyanoacrylate injection physically seal high-risk esophageal and gastric varices.
+----------------------------+-------------------------------------+------------------------------------+
| Therapeutic Modality | Primary Mechanism of Action | Clinical Indication |
+----------------------------+-------------------------------------+------------------------------------+
| Non-Selective Beta-Blockers| Splanchnic vasoconstriction | Primary & secondary variceal prophylaxis|
| Terlipressin / Octreotide | Acute splanchnic pressure reduction | Acute esophageal variceal bleeding |
| TIPS Stent Placement | Portosystemic vascular shunting | Refractory ascites & recurrent varices|
| Endoscopic Banding (EVL) | Mechanical variceal obliteration | Localized variceal hemobasis |
