What is the management approach for a patient with acute massive pulmonary embolism (PE) and upper gastrointestinal bleeding (UGIB) from a duodenal ulcer?

Management of Acute Massive PE with Concurrent UGIB from Duodenal Ulcer

This is a life-threatening dual emergency requiring simultaneous hemodynamic resuscitation, urgent endoscopic hemostasis for the bleeding ulcer, and cautious anticoagulation management for the massive PE—prioritize immediate stabilization, early endoscopy within 24 hours without delaying for coagulopathy correction, and consider catheter-directed therapy or embolization over systemic thrombolysis for the PE given the absolute contraindication of active bleeding.

Immediate Resuscitation and Stabilization

Initiate aggressive resuscitation immediately for both conditions simultaneously:

• Hemodynamic resuscitation is the first priority for patients with acute UGIB and hemodynamic instability 1
• Transfuse red blood cells at hemoglobin <80 g/L, or at a higher threshold if cardiovascular disease is present (which is likely given massive PE) 1, 2
• Establish large-bore IV access, administer crystalloids, and prepare for massive transfusion protocol if needed 3, 4
• Monitor in an intensive care setting where both cardiac parameters and bleeding can be closely observed 2

Critical Decision Point: Anticoagulation Management

The massive PE requires anticoagulation, but active UGIB creates an absolute contraindication to systemic thrombolysis:

• Do NOT use systemic thrombolytic therapy (alteplase, tenecteplase) given active bleeding—this would be catastrophic
• Avoid full-dose systemic anticoagulation initially until bleeding is controlled endoscopically
• Consider catheter-directed therapy, surgical embolectomy, or mechanical thrombectomy for the massive PE as these avoid systemic thrombolysis while addressing the life-threatening clot burden
• If anticoagulation is already on board, do not delay endoscopy for coagulopathy correction—proceed with endoscopy while correcting coagulopathy simultaneously 1

Endoscopic Management of UGIB

Proceed with urgent upper endoscopy within 24 hours, ideally sooner given the massive PE complicating the clinical picture:

• Do not delay endoscopy even in the setting of coagulopathy from anticoagulants 1
• Administer pre-endoscopic erythromycin 30-60 minutes before endoscopy to improve visualization 3, 5, 6
• Start high-dose intravenous PPI therapy immediately (bolus followed by continuous infusion) to downstage lesions, though this should not delay endoscopy 1, 5, 6
• Endoscopic hemostatic therapy is indicated for duodenal ulcers with high-risk stigmata (active bleeding or visible vessel) 1
• Use combination therapy: epinephrine injection PLUS thermal coagulation (bipolar electrocoagulation or heater probe) or clips—never epinephrine alone 1, 5, 6

If Endoscopic Hemostasis Fails

Have a backup plan ready before starting endoscopy:

• Transcatheter arterial embolization is the preferred salvage therapy if endoscopic hemostasis fails, especially in high-surgical-risk patients 7, 6
• Embolization can be performed with high technical and clinical success rates (>85%) for refractory gastroduodenal bleeding 7
• Surgery is reserved for patients who fail both endoscopic and interventional radiology approaches 5, 6

Anticoagulation After Hemostasis

Once endoscopic hemostasis is achieved and bleeding is controlled:

• Resume anticoagulation as soon as possible (typically within 24-72 hours) given the massive PE carries extremely high mortality risk without treatment 2
• The risk of PE-related death outweighs rebleeding risk once hemostasis is secured 2
• Continue high-dose PPI therapy (continuous infusion for 72 hours, then twice-daily oral dosing) to minimize rebleeding risk 5, 6
• Monitor closely for at least 72 hours after endoscopic hemostasis for both rebleeding and cardiovascular complications 2

Common Pitfalls to Avoid

• Never give systemic thrombolytics (alteplase, tenecteplase) in the setting of active GI bleeding—this is an absolute contraindication
• Do not delay endoscopy waiting for INR normalization or platelet transfusions—proceed with endoscopy while correcting coagulopathy 1
• Do not use epinephrine injection alone for endoscopic hemostasis—it has suboptimal efficacy and must be combined with thermal or mechanical therapy 1
• Do not withhold anticoagulation indefinitely after hemostasis—the massive PE will kill the patient faster than rebleeding in most cases 2

Multidisciplinary Coordination Required

This scenario demands real-time collaboration:

• Involve gastroenterology, interventional cardiology/pulmonology, interventional radiology, and critical care simultaneously 1
• Have interventional radiology on standby for potential embolization of bleeding vessel or catheter-directed PE therapy 7, 6
• Consider ECMO or mechanical circulatory support if the patient is in cardiogenic shock from massive PE while awaiting definitive therapy
