de Leval法による修正大血管転位症｛S,L,L｝・心室中隔欠損・肺動脈閉鎖の1手術治験例

A successful operation by de Leval's procedure for the corrected transposition of the great arteries with ventricular septal defect and pulmonary atresia

　今回，我々は10歳男児の修正大血管転位症・心室中隔欠損・肺動脈閉鎖に対し，de Level法による心室中隔欠損（VSD）の閉鎖と，external conduitによる解剖学的左室-肺動脈間の再建からなる機能的根治術を行い良好な結果を得たので報告する。

A ten-year-old boy with C-TGA {S,L,L} asso-ciated with ventricular septal defect and pulmonary atresia underwent an intracardiac repair successfully.

Its repair was consisted of VSD closure by de Leval's procedure and relief of pulmonary atresia by means of external valved conduit (18 mm Inonescu-ShileyR® valved conduit).

Sutures for VSD closure were placed to upperhalf margine of VSD from the anatomic right vent-ricle and lower half margine from the anatomical left ventricle, as which de Leval and co-workers have discribed previously.

De Leval's procedure is superior than other VSD closure methods at the point of reduced A-V block, relatively easy operative technique, and good opera-tive field.
