[Surgical treatment of pulmonary embolism].
BACKGROUND
Surgical embolectomy is established method of treatment of pulmonary embolism. The aim of the study is to evaluate the experience with this procedure.


METHODS
Twenty two patients, aged 22-77 years, were operated on in Centre of cardiovascular surgery and transplantation in Brno from 1999 to 2009. Nine patients suffered from massive pulmonary embolism with hemodynamic instability, 13 were stable. All the operations were performed in cardiopulmonary bypass with cross clampimg time 50.4 minutes on average. In six patients the retrograde perfusion via pulmonary veins were used. Emboli in the main trunk and/or in both pulmonary branches were found in 16 patients (72.7%). No macroscopic emboli were found in three patients, but they were flushed from the pulmonary vessels during the retrograde perfusion in two of them. Emboli or thrombi in cardiac atria or ventricles were detected in 8 patients simultaneously.


RESULTS
Five patients died early after operation (mortality 22.7%). The mortality was different in the group of patients with massive pulmonary embolism and cardiogenic shock (44.4%) and with submassive embolism and hemodynamic stability (7.7%).


CONCLUSIONS
Developments in surgical technique with retrograde perfusion offer removing of emboli not only from the pulmonary trunk and main branches, but also from the peripheral branches. It improves results and facilitates extension of indications for surgical treatment.
