[Vascular aspects of experimental transplantation of the kidney in dogs].
Organ transplantation is predominantly vascular surgical procedure. Vascular aspects of renal transplantation are important in all surgical phases of this procedure: --donor-nephrectomy (living-related or cadaver nephrectomy)--include nephrectomy undamaged kidneys, each with good length of renal artery (with or without aortic patch), renal vein (with or without caval patch) and ureter --organ-ex situ-surgery (bench surgery) sometimes is necessary after cold perfusion with Collins solution --implant surgical procedure, which include--dissection of recipient vessels (localisation.) --venous anastomosis (type and technique) --arterial anastomosis (type and technique) --use of vascular grafts (autografts or alografts) for kidney revascularisation during implantation (???) In the period 1987-1988, in our Experimental Surgery Unit a total of 20 dogs were operated (experimental kidney autotransplantation) under the same surgical team. The aims of those experimental autotransplantations were: training of the surgical team for routine human renal transplantations and usefulness of vascular grafts (autografts or allografts) for kidney revascularisation. We divided animals into the three groups: The first group (5 dogs)--revascularisation using AUTOVENOUS grafts The second group (5 dogs)--revascularisation using ALLOGRAFTS (Dacron or e-PTFE-Goretex grafts) The third group (10 dogs)--direct revascularisation without vascular grafts (control group) The best results were in the third group (no early vascular thrombosis) especially with end-to-end arterial anastomosis (we prefer it) and end-to-side venous anastomosis. Unfortunately in the second group, results were bad (vascular anastomotic thrombosis in the all cases during the first 48 hours).(ABSTRACT TRUNCATED AT 250 WORDS)
