[Anatomical considerations on the renal arterial segmentation]. / Consideratii anatomice asupra segmentarii arteriale a rinichiului.

ABSTRACT

We studied the arterial segmentation of the kidney observing the basic mode of finishing of the renal arteries and the distribution of the second order arteries in renal parenchyma. Our study was performed on 194 human kidneys resulted by evisceration and we have also analyzed the renal angiographies. As methods of study we used dissection, injection of plastic material followed by corrosion. In 10.82% of cases we found 3 arterial segments anterior; posterior; inferior polar (basal). In 39.69% of cases au we found 4 arterial segments apical (superior polar); middle (meso-ventral); inferior (basal or inferior polar); posterior (retro-pyelic). We found 5 arterial segments in 83 kidneys (42.78%). The 5 arterial segments are as follows apical (superior polar); superior (meso-ventral superior); middle (meso-ventral inferior); inferior (basal or inferior polar); posterior (retro-pyelic). In 13 cases (6.7%) we found 6 renal arterial segments superior polar (apical); superior pre-pyelic (meso-renal superior); middle pre-pyelic (middle meso-renal); inferior pre-pyelic (meso-renal inferior); inferior polar (basal); retro-pyelic (posterior).
