The implantation of microvascular dacron grafts (MDG) (internal diameter=1mm,length=10mm) in carotid arteries was studied in 48 Sprague Dawley rats.The left carotid artery was resected 7mm in length and replaced with MDGs by means of sleeve anastomosis.Postoperatively,the patency was monitored with Doppler ultrasound at 24 and 72 hours,and 1,2,3,4,8 and 12 weeks respectively and confirmed either by direct inspection intraoperatively or by angiography at time of removal.At each time,all the thrombosed...

The implantation of microvascular dacron grafts (MDG) (internal diameter=1mm,length=10mm) in carotid arteries was studied in 48 Sprague Dawley rats.The left carotid artery was resected 7mm in length and replaced with MDGs by means of sleeve anastomosis.Postoperatively,the patency was monitored with Doppler ultrasound at 24 and 72 hours,and 1,2,3,4,8 and 12 weeks respectively and confirmed either by direct inspection intraoperatively or by angiography at time of removal.At each time,all the thrombosed and some selected patent grafts were removed and prepared for scanning electron microscopic study.The early patency rate was 100 percent within 24 hours and the cumulative long term patency rate was 77.1 percent in 12 weeks.Rapid and complete endothelial lining was demonstrated in three weeks which provided a smooth and nonthrombogenic surface,and contributed to the patency.Ten of the 11 failed grafts occurred within three weeks due to thrombosis before endothelial lining.These observations indicate that MDGs can be successfully used as arterial conduits in rats and suggest that an enhanced patency may be expected with the use of platelet inhibitor or endothelial seeding for the prevention of early thrombosis.(Original article on page 198)

采用48只SD雄性大鼠,切除7mm一段左颈总动脉,以10mm长、1.0mm内径的涤纶小血管桥接之.术后24、72小时及1、2、3、4、8和12周分别以多普勒超声监测血流通畅情况.每次随访时,对5例通畅者(8周时3例,12周时4例)及所有不通畅者行手术探查或血管造影检查,以进一步证实多普勒检查结果的正确性,同时取下桥接血管.部分桥接血管经处理后作扫描电镜检查.结果显示桥接后12周的累积通畅率为77.1%.快速而完全的内皮化过程在桥接后3周即完成,形成一光滑的内皮细胞层.11例桥接血管因血栓形成而失败,其中10例发生在桥接后3周之内,即内皮化之前.提示涤纶小血管可成功地用于大鼠颈总动脉桥接,失败主要发生在内皮化之前,其原因为血栓形成,若用抗凝药物或内皮细胞种植防止早期血栓形成,可望进一步提高通畅率,有可能使其成功地用于临床.

Dacron graft impregnated with 4mg/ml purified type I collagen harvested from bovine skin was crosslinked with O.3% glutaraldehyde. The water porosity decreased from 383+28ml . min-1/cm2to 2. 8+0. 5ml . mm-1V/cm2. The in-frarenal abdominal aorta of 16 mongreal dogs was replaced with 4cm X 0. 8cm Decron grafts (8 collagen-coated and 8 autoclaved albumin for control)>No interstitial bleeding occurred in either type of grafts. By gross observation and under light microscopy, a smooth neointima was noticed on the surface of collagen coated grafts 30 and 90 days after implantation. In a series of 4 patients with Marfan's syndrome undergoing replacement of the aortic root, hemorrhage through the interstices of the graft was virtually eliminated. There was no complication in any patient after a follow up of 3 months. This study reveals that collagen-coated dacron grafts were totally impervious to blood during and after implantation. The collagen coating can promoting cell growth and graft healing and does not interfere with the physical properties of the dacron grafts. As a prosthesis of aorta replacement , it may be applied clinically with safety. If it is used as small diameter vascular prosthesis,the long-term patency may be improved.

提取牛皮Ⅰ型胶原蛋白,以4mg/ml的胶原蛋白溶液涂层苏州涤纶人工血管,经过0.3%戊二醛交联,涤纶血管渗水量由383±28ml·min~(-1)/cm~2降至2.8±0.5ml·min~(-1)/cm~2。将胶原蛋白涂层涤纶血管移植犬腹主动脉下段,以白蛋白涂层涤纶血管移植为对照。在肝素化状态下均不渗血。术后30天和90天观察显示,胶原涂层涤纶血管内壁覆盖一层完整光滑的内膜,光镜显示为纤维结缔组织,表面有内皮细胞被覆并与自体动脉内膜延续。而白蛋白涂层涤纶血管血栓形成率高,内壁纤维素沉积。临床采用胶原涂层涤纶血管为4例马凡综合征病人行主动脉根部替换,术中涤纶血管不渗血,随访3个月无不良反应。本研究显示胶原涂层涤纶血管机械性能良好,不渗血,尤其能促进涤纶血管的愈合。作为主动脉移植材料可广泛应用于临床,若用于中小血管移植可望提高远期通畅率。
