## Management of Acute Variceal Bleeding **Key Point:** Acute variceal hemorrhage is a medical emergency requiring simultaneous hemodynamic resuscitation, pharmacological vasoconstriction, and definitive endoscopic therapy. ### Pathophysiology of Portal Hypertension In cirrhotic patients, increased intrahepatic resistance leads to portal hypertension (portal pressure gradient >12 mmHg). This drives formation of portosystemic collaterals, including esophageal varices. Rupture causes life-threatening hemorrhage. ### Management Algorithm for Acute Variceal Bleeding ```mermaid flowchart TD A[Acute variceal hemorrhage]:::outcome --> B[Hemodynamic assessment]:::decision B -->|Unstable| C[Aggressive IV resuscitation<br/>Blood products, crystalloids]:::action B -->|Any patient| D[Vasoactive drugs:<br/>Terlipressin or Octreotide]:::action C --> E[Prophylactic antibiotics<br/>Ceftriaxone]:::action D --> E E --> F[Urgent endoscopic therapy<br/>Variceal ligation preferred]:::action F --> G{Hemostasis achieved?}:::decision G -->|Yes| H[Continue vasoactive drugs<br/>5 days, then taper]:::action G -->|No| I[Rescue therapy:<br/>TIPS or repeat endoscopy]:::urgent ``` ### Why This Approach Works | Step | Rationale | Timing | |------|-----------|--------| | IV fluids & blood products | Restore intravascular volume; target Hb 7–9 g/dL | Immediate | | Vasoactive drugs (terlipressin/octreotide) | Reduce portal pressure & variceal flow; ↓ rebleeding risk | Within 1 hour | | Prophylactic antibiotics | Prevent bacterial peritonitis & sepsis (major mortality driver) | Within 1 hour | | Endoscopic variceal ligation (EVL) | Definitive hemostasis; superior to sclerotherapy | Within 12 hours | **Clinical Pearl:** Terlipressin (a vasopressin analogue) is superior to octreotide in reducing mortality in acute variceal bleeding because it has longer half-life and more sustained splanchnic vasoconstriction. However, octreotide is more commonly used in resource-limited settings and is acceptable. **High-Yield:** The combination of vasoactive drugs + endoscopic therapy achieves hemostasis in ~80% of cases. Vasoactive drugs should be continued for 2–5 days even after successful endoscopy to prevent early rebleeding. **Mnemonic:** **ABCE** for acute variceal bleeding: - **A**ntibiotics (prophylactic) - **B**lood products & resuscitation - **C**ontrol (vasoactive drugs) - **E**ndoscopic therapy ### Why Option 3 Is Incorrect Observation without vasoactive drugs and endoscopic intervention has a mortality rate >50% in acute bleeding. Prophylactic antibiotics alone do not control hemorrhage.
