Esophageal varices (EV) Flashcards
Pathophysiology
Portal HTN causes hepatic/splanchnic vasodilation resulting in decreased perfusion that causes compensatory varices or small offshoots
May result in bleeding
Risk factors for Variceal Bleeding
Large varices
Severity of cirrhosis
Red color markings on imaging
Active alcohol use
Symptoms
Hematemesis
Melena
Fatigue
Hypotension, lightheadedness
Prophylaxis treatment
Non-selective beta blocker
When? Moderate disease
Why?
B1 antagonism: decreased HR and CO
B2 antagonism: splanchnic vasoconstriction
Nadolol
Initial: 20-40 mg PO QD
Max: 80 mg (if ascites); 160 mg (if not ascites)
Propranolol
Initial: 20-40 mg PO BID
Max: 160 mg (if ascites); 320 mg (if not ascites)
Carvedilol
Initial: 6.25 mg PO QD/BID
Max: 12.5 mg PO QD
Monitoring
BP: Goal SBP > 90 mmHg
HR: Goal 55-60 bpm
Endoscopic variceal ligation
What? Bands off varices
When? Management of acute variceal bleed
Secondary management
Non-selective BB: continue indefinitely
Endoscopic variceal ligation: every 1-4 weeks
Octreotide
Acute management
