Abstract

The effects of tissue ingrowth on the compliance of porous Dacron grafts were studied in 8 mm external-velour warp-knit Dacron grafts implanted in the canine descending thoracic aorta. The compliance of these grafts was measured before implantation and after implant periods of two weeks and one, two, four, and six months. Compliance, which initially was 0.043 +/- 0.008% mm Hg, decreased less than 10% after implantation (no statistical difference at p less than 0.05). No anastomotic neointimal hyperplasia was observed. Although the total thickness of the graft wall increased two- to three-fold after implantation, the benign healing process observed in this study had very little influence on graft compliance followed to six months.

摘要

在植入犬降胸主动脉的8毫米外部带毛圈经编涤纶移植物中，研究了组织长入对多孔涤纶移植物顺应性的影响。在植入前以及植入两周后和一、二、四、六个月的植入期后，测量这些移植物的顺应性。顺应性最初为0.043±0.008%/mmHg，植入后下降不到10%（p小于0.05时无统计学差异）。未观察到吻合口内膜增生。尽管植入后移植物壁的总厚度增加了两到三倍，但本研究中观察到的良性愈合过程对长达六个月的移植物顺应性影响很小。
