[慢性血栓塞栓性肺高血圧症の肺内膜切除術の麻酔管理 - 重度の症例のシリーズ]

過去7年間の病院での慢性血栓塞栓性肺高血圧症（CTEPH）の肺内膜摘出術の麻酔管理の7例を報告します。すべての患者は右心不全と肺高血圧症に苦しんでおり、術前平均肺動脈圧（MPAP）は51.2 +/- 10.2 mmHgであり、肺血管抵抗（PVR）は894.2 +/- 207.7 Dyne x Sec（ - 1）x cm（-5）。外科手術は、深部低体温と循環停止技術を使用して行われました。術後MPAPとPVRは、それぞれ15.5 +/- 7.5 mmHgと181.6 +/- 84 Dyne X秒（-1）X cm（-5）に減少しました。息切れや呼吸困難などの患者の症状は改善され、深刻な合併症なしに排出されました。

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.
