[Pulmonary thrombendarterectomy in treatment of patients with chronic thromboembolic pulmonary hypertension].
20 consecutive patients with thromboembolic pulmonary hypertension underwent pulmonary thromboendarterectomy. Mean pulmonary artery pressure decreased from mean 49.9 +/- 9.8 to 25.1 +/- 8.8 mm Hg (p < 0.0001), pulmonary vascular resistance decreased from mean 5.58 +/- 2.58 to 1.62 +/- 0.79 mm Hg/l*min-1 (p < 0.0001) and cardiac output increased from 3.71 +/- 1.18 to 6.92 +/- 1.64 l/min. Sixteen patients had marked clinical improvement. Two patients died in early and 2 patients in late postoperative period due to unrelieved pulmonary hypertension and postoperative complications.
