Pulmonary thromboendarterectomy (PTE) is a potentially curative procedure in chronic thromboembolic pulmonary hypertension. From June, 1989, to December, 1994, we performed PTE in 109 consecutive patients. Multiple changes in surgical approach and postoperative management have been implemented since January, 1995. We report the early results of 32 thromboendarterectomies performed from January, 1995, to January, 1997. Thirty-two patients (16 females, 16 males; mean age 55 years) were operated using cardiopulmonary bypass, deep hypothermia and circulatory arrest. Preoperative NYHA functional class was III in 21 and IV in 11 patients. Pulmonary vascular resistance (PVR) and mean pulmonary artery pressure (mPAP) were elevated to 967 +/- 238 dynes.s.cm-5 and 51 +/- 11 mm Hg respectively. The perioperative mortality rate was 9.3% (3 of 32). Twenty-nine survivors were weaned from mechanical ventilation and extubated after a mean of 35 hours (12 to 190 hours). PVR was reduced to 301 +/- 151 dynes.s.cm-5 (p0.001) and mPAP was reduced to 28 +/- 10 mm Hg (p0.001). Pulmonary thromboendarterectomy is an effective surgical procedure for chronic thromboembolic pulmonary hypertension. By means of modifications in surgical approach and postoperative management, early results can be improved and perioperative mortality can be decreased to less than 10%. |
