Background: Acute massive pulmonary thromboembolism is a rare emergent condition that cause sudden hypoxemia, right ventricular failure and death. Open pulmonary thromboembolectomy is indicated in the patient with hemodynamic instability or unsuitable for medical treatment.
Objective: To determine the surgical outcomes of open pulmonary thromboembolectomy in patients with acute massive pulmonary thromboembolism treated in Lampang Hospital.
Material and methods: A retrospective study was conducted on four consecutive patients (1 male and 3 female) with acute massive pulmonary thromboembolism who underwent open pulmonary thromboembolectomy in Lampang Hospital between January 2010 - November 2015.
Results: The mean age was 55.8 years (range, 41-68). All patients had risk factors for pulmonary thromboembolism and presented with shock. Pulmonary thromboembolectomy was performed in all patients under cardiopulmonary bypass. Postoperatively, three patients survived in NYHA functional class I with significantly decreased right ventricular pressure. There was one hospital death (25%) from decompensated shock with renal failure.
Conclusion: Open pulmonary thromboembolectomy is a simple and life-saving procedure with 25% operative mortality rate. Early diagnosis and immediate surgery prior to multi-organ failure may decrease mortality rate.
