Abstract
BACKGROUND Variations in origin, course and distribution of renal blood vessels are frequent observations. The aim of this study was to observe the pattern of posterior segmental renal artery by corrosion cast method. METHODS Thirty pairs of kidneys were collected from cadavers in anatomy department of Subharti Medical College, Meerut. Corrosion casts of renal arteries were prepared by infusing cellulose acetate butyrate solution through abdominal aorta. They were macerated in conc. hydrochloric acid. Origin, course and distribution of the posterior segmental artery were studied. RESULTS Renal posterior segmental artery most frequently originated as a continuation of the posterior division (93 %). It has no anastomosis with nearby segmental arteries. CONCLUSIONS Posterior segmental artery supplies posterior segment of kidney and may also frequently give origin to apical segmental artery. This study of origin, course, distribution and variations of renal posterior segmental artery will be useful for surgical and radiological practice.
