Variceal Bleed on Direct Oral Anticoagulant
67-year-old man with alcohol-related cirrhosis (Child-Pugh C) and atrial fibrillation on apixaban 5 mg twice daily presents with hematemesis and melena. Last apixaban dose was 10 hours ago. He is confused but protecting his airway. Blood pressure 88/54 mm Hg, heart rate 122 beats/min, hemoglobin 6.9 g/dL, platelets 78,000/uL, INR 1.8, creatinine 1.6 mg/dL. The ED has octreotide, ceftriaxone, and 2 units of packed red blood cells immediately available. Endoscopy suite is available in 4 hours; interventional radiology and TIPS are not available. The patient has no known variceal bleed history.
1. What are your initial resuscitation targets and blood product strategy, including reversal of apixaban?
Read the worked answer
Resuscitate with balanced crystalloids and blood products, targeting a hemoglobin of 7-8 g/dL; in a patient with active massive hemorrhage and cardiac risk, a higher threshold may be considered, but overtransfusion can raise portal pressure and worsen bleeding. Give packed red blood cells (2 units available) and activate massive transfusion if needed. For apixaban reversal, use andexanet alfa if available; otherwise give 4-factor prothrombin complex concentrate (50 units/kg) or activated PCC. Fresh frozen plasma is less effective for direct factor Xa inhibitors. Check fibrinogen and platelets; transfuse platelets if <50,000/uL. Avoid vitamin K unless there is concurrent warfarin use. Correct hypocalcemia and acidosis. Use viscoelastic testing if available.
2. What pharmacologic therapy and prophylactic antibiotics would you give, and when should endoscopy occur?
Read the worked answer
Start octreotide 50 mcg IV bolus followed by 50 mcg/hour infusion. Give ceftriaxone 1 g IV daily for prophylaxis in cirrhotic patients with GI bleeding. Consider a proton pump inhibitor, although its role in variceal bleeding is adjunctive. Resuscitate before endoscopy, but do not delay endoscopy excessively; current guidelines recommend endoscopy within 12 hours. Here the suite is available in 4 hours, so proceed then if the patient is stabilized. If the patient remains hypotensive despite resuscitation, endoscopy may need to be performed earlier with airway protection. Intubate if there is ongoing hematemesis or altered mental status to protect the airway during endoscopy.
3. If endoscopy fails to control bleeding, what options remain and how would you decide?
Read the worked answer
If endoscopic therapy fails or is unavailable, use balloon tamponade (Sengstaken-Blakemore or Minnesota tube) as a bridge to definitive therapy. This requires airway protection and careful positioning. Since TIPS and interventional radiology are unavailable, transfer the patient to a center with TIPS or surgical shunting. Decide based on hemodynamic stability, airway status, and local resources. If the patient is too unstable to transfer, place a balloon tamponade tube and continue octreotide and antibiotics. Avoid prolonged tamponade (>24 hours) because of pressure necrosis. Consider rescue TIPS if transfer is possible. Surgical shunt or devascularization is a last resort. The key judgment is not to delay transfer while waiting for endoscopy that may not control the bleed.
