“…5 The use of bovine carotid artery (BCA) heterograft for hemodialysis access was first reported by Chinitz et al 6 and was used extensively by many centers in the 1970s. [7][8][9][10][11][12][13][14][15][16] However, with the advent of ePTFE grafts later that decade, BCA grafts fell out of favor despite the lack of data to account for the change in paradigm. 16 With the efficient and effective endovascular techniques now available to manage complications along with improvements to BCA manufacturing, we felt revisiting BCAs as AV conduits for hemodialysis would be worthwhile.…”

“…Heterologous arterial grafts have been used in several situations experimentally as well as clinically with different periods of follow-up and different results [1][2][3][4][13][14][15][16][17][18][19]. The main problem with these grafts was tissue degeneration after long-term implantation.…”

Objective: The No-React process for biomaterials was suggested to prevent calcification and degeneration. We examined in vivo in a chronic sheep model the performance of a Biocor bovine internal mammary artery (BIMA) graft after No-React processing. Methods: ‘No-React’ processing consists of aldehyde cross-linkage following a detoxification process with multiple physical variables and incubation with surfactant. Biocor BIMA No-React treated grafts have been interposed in the carotid artery in seven sheep with a Dacron graft as control. Grafts were explanted after 3 or 6 months and were grossly examined, by X-ray, histology, transmission and scanning electron microscopy, and atomic absorption spectrophotometry. Results: In the BIMA, good healing was found with a smooth intimal surface, minimal inflammatory reaction, and a well preserved ultrastructure. Calcification increased progressively. In the Dacron grafts, a fibrous covering the inner surface and infiltration with fibroblasts, histiocytes and macrophages was noted. Calcium content was stable. Conclusion: Calcification increased progressively in Biocor BIMA No-React grafts. Minimal inflammatory changes, a smooth inner surface and well preserved ultrastructure were noted.

The effectiveness of human ureter grafts tanned by polyepoxy compound for small diameter arterial substitution was examined in 8 carotid arteries of rabbits, followed by an observation period of either 1 month (n = 6) or 6 months (n = 2). In this model there was no evidence of rejection, aneurysm formation, or infection. The modified human ureter showed excellent patency in all cases as well as excellent function, and the histological evaluation revealed monolayer endothelial-like cells covering all of the surface of the graft as was expected. No intimal hyperplasia was demonstrated at either anastomotic site. This study suggests that our newly designed polyepoxy compound fixed human ureter could serve as a satisfactory blood conduit with good long-term patency for substitution.
