The surgical option in the management of acute pulmonary embolism.
OBJECTIVE
Massive or submassive pulmonary embolism (PE) carries a high mortality. Traditionally this condition has been treated with thrombolysis or anticoagulation and support measures. Surgical embolectomy is carried out in situations of hemodynamic instability or contraindication for thrombolysis. We present our results of surgical embolectomy in patients with massive and submassive PE.


METHODS
Over a three-year period, we have carried out 20 surgical embolectomies for acute PE. The mean age was 66 years, and there were 11 males. In all cases, the diagnosis had been made by a computerized tomography (CT) pulmonary artery angiography. Nine patients (45%) arrived to the operating theater on inotropes, and two of them (10%) with ventilatory support. All patients underwent a median sternotomy, bicaval cannulation for institution of cardiopulmonary bypass (CPB), and main pulmonary arteriotomy for the removal of the thrombus.


RESULTS
The mean bypass time was 45 minutes. Two patients (12%) died after being unable to wean off CPB due to right heart failure. Among the 15 survivors, the median ventilation time in the intensive care unit was 24 hours. Twelve patients (60%) required inotropic support postoperatively for right heart failure. All but one survivor (94%) underwent an insertion of a permanent inferior vena cava filter and were anticoagulated with coumarin. The mean follow-up is 9.8 months and is 100% complete, with a survival of 94.5%. All patients were in the World Health Organization (WHO) functional class I, with no re-admissions for respiratory failure.


CONCLUSIONS
In patients with acute massive or submassive PE, surgical embolectomy offers a valid therapeutic strategy. A right-sided heart failure is the main complication of this condition.
