有活性同种异体血管的研究及临床应用

Basic Study and Clinical Application of the Viable Homograft

经检测采用抗生素灭菌、超低温（１９６℃）方法保存同种异体血管效果可靠，可有效的保存动脉壁的组织结构和细胞活性。这种有活性同种异体血管可作为血管移植的代血管材料，与人工血管相比，有较多的优越性。１９９３年１月至１９９６年１月，我们为１４例尿毒症病人应用有活性同种异体血管作透析移植血管搭桥术。

Aim:To evaluate the basic features and clinical application of viable homograft as an substitute for vascular transplantation.Method:The homografts were preserved using the method of sterile antibiotic solution and extrahypothermia( 196℃).From 1993 to 1996,14 patients with uremia(8 males,6 females with age of 32 to 79years)underwent graft arteriovenous fistulas for hemodialysis using viable preserved homografts.Result:The examination of preserved homograft indicated that preserve method is reliable and effective in preserving the tissue structure and cell activity of artery wall.The short term result of surgery is satisfied.Conclusion:The viable homograft can be used as vascular substitute safely and effectively.There are many advantages when compared to prothetic vessel.
