For a suspected massive perioperative pulmonary embolism, which therapy is considered if there are no contraindications?

• A. Heparin anticoagulation and thrombolysis if massive
• B. Antibiotics
• C. Surgery immediately
• D. Observation

Answer: (A)

In a life-threatening, massive pulmonary embolism during the perioperative period, the priority is rapid reperfusion to restore blood flow and save the patient’s life. If there are no contraindications, the best approach combines immediate heparin anticoagulation with systemic thrombolysis. Unfractionated heparin is started right away to prevent new clot formation and to stop propagation of the existing thrombus. In a massive PE that is causing hemodynamic instability, systemic thrombolysis is indicated to quickly dissolve the obstructing clot, relieve right heart strain, and improve oxygenation and perfusion. This combination addresses both preventing further clots and actively dissolving the dangerous blockage. Antibiotics don’t treat a thromboembolic event, so they aren’t appropriate here. Surgery right away isn’t the first-line therapy for a massive PE unless thrombolysis is contraindicated or has failed, because surgery carries its own risks and is typically reserved for specific scenarios like failed thrombolysis or contraindications to thrombolysis. Observation would miss the ongoing obstruction and is not appropriate in a massive event. So, initiating heparin anticoagulation along with thrombolysis if massive and no contraindications best addresses the urgent problem of a large pulmonary embolus in the perioperative setting.
