体外循环技术用于非心脏外科手术8例

Extracorporeal Circulation for Noncardiac Operations: 8 Cases Report

自１９９１年７月至１９９４年１月我们将体外循环（ＥＣＣ）技术用于非心脏外科手术８例，其中ＥＣＣ并深低温停循环（ＤＨＣＡ）用于布－加氏综合征根治术４例；肾癌伴下腔静脉瘤栓行肾及瘤栓摘除术２例；静脉－静脉体外氧合辅助循环用于气管癌激光造孔者行气管腔内记忆合金成形架植入术２例。８例中除１例肾癌伴下腔静脉瘤栓病人术后合并急性肾功能衰竭死亡外，余均存活且获得了良好的手术效果。体外循环技术常规用于心内直视手术，但近年来将此技术用于非心脏外科手术时有报道。我们就体外循环技术在非心脏外科领域中的应用进行了探讨，旨在拓宽其应用范围，为某些疑难、重症病人提供新的救治手段。

From Nov. 1991 to Jan. 1994, 8 patients underwent noncardiac operations using the technique of extracorporeal circulaton (ECC).The technique of ECC and deep hypothermic circulatory arrest (DHCA) were used in radical operation of Budd-Chiari syndrome (n=4) and nephrectomy and resection of inferior venae cava (IVC) tumor thrombi from renal cell carcinoma (n =2 ). Veno-venous extracorporeal oxygenation was used in resection of tracheal carcinoma by laser and implantation of shaped memory alloy stent (n=2).One patient died from renal failure postoperatively, the rest were alive and in good condition after the operation..The technique of ECC and DHCA is effective in decreasing some operative risk and increasing the feasibility of resection of tracheal tumor or IVC or some other complex surgical lesions. The extended use of ECC in noncardiac surgery was discussed in the hope that it could be used in a wider range of indicated procedures.
