title: [Anesthetic management of pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension--series of severe cases].
abstract: We report seven cases of anesthetic management for pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension (CTEPH) during past seven years in our hospital. All the patients were suffering from right heart failure and pulmonary hypertension, and the preoperative mean pulmonary artery pressure (mPAP) was 51.2 +/- 10.2 mmHg, and the pulmonary vascular resistance (PVR) was 894.2 +/- 207.7 dyne x sec(-1) x cm(-5). The surgical operation was performed using the deep hypothermia and circulatory arrest technique. The postoperative mPAP and PVR decreased to 15.5 +/- 7.5 mmHg and 181.6 +/- 84 dyne x sec(-1) x cm(-5), respectively. The patients' symptoms such as shortness of breath, and dyspnea improved and they were discharged without any serious complications.
