title: ["Ex situ" reconstruction of blood vessels of the renal hilus in experimental transplantation in dogs].
abstract: The variations of arterial and venous hillar blood vessels in human kidneys are numerous and surgical transplant teams have to know them. It is very important during doner-nephrectomy for transplantation. Sometimes, after doner, nephrectomy and kidney cold perfusion with Collins, there is a need for vascular repair of kidney hillar blood vessels, using microvascular surgical technique. The aim of this repair is: to have a kidney with main renal artery of good length and size and with main renal vein of good length and size. This procedure is called: extracorporeal "ex-situ" vascular repair of kidney hillar blood vessels. In the period 1987-1988, in our Experimental Surgery Unit a total of 20 dogs were operated on (kidney autotransplantation) and only in four (4) dogs we found variations in numbers of kidneys arterial and venous hillar blood vessels (20%) and repaired those vessels after cold perfusion of kidney. One dog had kidney with double renal arteries and double renal veins, and we had to make fusion the both arteries into the main renal artery of good size (5 mm) and the both veins into the renal vein of good size (12 mm). Three dogs had kidneys with main trunk of renal artery and one important separate polar renal artery, and we had to make implantation of separate polar renal artery into the main trunk of renal artery (end-te-side vascular anastomosis). For those vascular reconstructions we used polipropilene 6-o or -o as suturae material and binocular (magnification 2.5 x). The hemodynamically results of those reconstructions immediately after kidney implantation were very satisfactory.
