膨体聚四氟乙烯人工心包膜

Prevention of Pericardial Adhesion After Median Sternotomy in Pediatric Patients

对１８例法乐四联症患儿胸骨正中进胸，行姑息术后置入膨体聚四氟乙烯人工心包膜以替代心前区心包关闭心包腔。年龄２～７岁。再进胸行根治手术时发现，纵隔纤维粘连显著减轻，无一例损伤心脏或大血管。病理检查显示，仅少量纤维组织覆盖于人工心包膜及心脏表面，无组织细胞经薄膜微孔浸润。因其性能稳定、使用方便、效果良好，值得临床推广。

Expanded polytetrafluoroethylene (ePTEF) surgical membrane was used in primary pericardial closure during palliative procedures in 18 patients with Tetralogy of Fallot (TOF). The age ranged from 2 years to 7 years(mean 5. 6± 2. 21 years). They were reoperated between 18-84 months (mean 35. 3± 17. 99 months) after the first procedure. No injury occured in the reentry though the sternum in ePTFE group. One death, unrelated to this technique, was due to postoperative cardiac failue after a radical operation. The epicardiac structure was easily identifide during reoperation. The ePTFE membrane significantly reduces the formation of pericardial adhesion(P<0.05)
