Abstract:
Massive pulmonary embolism with haemodynamic instability has a high mortality. Traditionally these patients are treated with i.v. thrombolytic therapy. When this therapeutic approach is contraindicated, surgical embolectomy and most recently, percutaneous mechanical interventions are alternative treatment options. This case report presents a 73-year-old female with a residual hemiparesis secondary to a meningioma resection 45 days previously, who presented with progressive shortness of breath, accompanied by oppressive chest pain, hypotension, tachycardia and severe hypoxaemia. CT pulmonary angiogram confirmed a massive pulmonary embolism extending into the lobar branches bilaterally. The patient was treated with percutaneous mechanical thrombectomy with excellent haemodynamic and clinical outcomes.
