RESUMO
We operated on a total of twenty-seven patients presenting with acute massive thromboembolism of pulmonary arteries. The patients' mean age amounted to 38.6 ± 9.17 years. The estimated pressure in the pulmonary artery averaged 54.2 ± 7.15 mm Hg. A total of twenty- two thromboembolectomic procedures were performed in the setting of assisted circulation. In five patients embolectomy was carried out from a thoracotomic approach without artificial circulation. The remote period was marked by a relapse of thromboembolism, with the female patient having completely refused to undergo treatment. All the patients remain in a satisfactory condition, with the estimated pressure in the pulmonary artery maintaining at an average level of 27.05 ± 3.11 mm Hg.
