Backgrounds: Renal arteries are two large blood vessels branching laterally from the abdominal aorta just below the superior mesenteric artery. The arteries vary in their level of origin and caliber, obliquity and precise relations. Each renal artery is about 6-8mm diameter. There is a varying characteristic of these arteries owing to their different course. The aim of the study was to study the variation in the formation of renal artery with its branching pattern using CT Angiography. Methods: The study was conducted in the department of Radiology at Chitwan Medical College after obtaining ethical approval CMC-IRC. CT Angiogram was studied in 17 individuals who attended radiology department for angiography for different suspected abdominal and renal pathology. Results: Analyzing the result of the angiography we found the usual branching pattern of renal artery in 70.58% of the individual, with variations in remaining 29.42%. On studying the number of arteries supplying kidney, artery draining directly to hilum i.e. accessory renal artery was 2.95%. We found the average length of right renal artery ranged between 3.5cm to 6.0cm. Conclusions: The variations on this large lateral branch of abdominal aorta are common. Surgeons should exclude the possibility of presence of accessory and aberrant renal arteries obstruction prior to the surgical procedure. The awareness about the presence of such variations is important from the academic, surgical and radiological aspect.

Histo-pathological findings in kidneys with polar artery: a demystifying endeavor

Background: The kidneys are supplied by renal arteries which enter the hilum and branch progressively from the pyramids to the cortex into lobar, interlobar, arcuate, interlobar, interlobular, and finally terminate as afferent arterioles that enter the glomeruli. Thus there is a normal pattern of blood flow towards the cortex from the pyramids when the artery enters at the hilum. The aim of the study was to explore the glomeruli pattern in kidneys with polar arteries.Methods: The study was conducted in the department of anatomy at a tertiary care referral institute. Twenty-two kidneys with polar arteries were obtained by conventional method of dissection from cadavers for the study. Sections were taken from the upper pole and lower pole in each kidney. The sections were taken perpendicular and close to the polar arteries. The sections were subjected to routine histological processing and staining as per the standard operating procedure. Histological findings were observed and documented.Results: The study found that the kidneys were histologically different with polar arteries as compared to normal kidneys. The number of glomeruli per high power field was higher nearer to the polar arteries. The glomeruli were viable and not sclerosed. An agglomeration of arterioles were present close to the polar arteries but they were distinct and did not seem to be associated with glomeruli. Conclusions: The study found an agglomeration of arterioles, increased number of viable glomeruli and cystic changes associated with kidneys having polar artery. Thus this warrants a detailed study with special stains for research to elucidate the mechanisms of the circulation in polar arteries and correlation of the same findings with clinical conditions such as hypertension or any other diseases of the kidney.

“…A case report by Patil and Mishra 10 describes an inferior polar renal artery arising from the anterolateral aspect of the aorta, passing superficial to the ureter and testicular vein on the right side, and involving possible obstruction of the ureter or testicular vein concerned, which should be diagnosed prior to surgical treatment of hydronephrosis or varicocele. 10 Inferior polar arteries are found in 9% of the population. Some cases of inferior polar arteries can be responsible for vascular obstruction in the pelviureteric syndrome, which makes imaging essential.…”

The renal arteries arise from the lateral side of the abdominal aorta at the L2 vertebral level, just below the origin of the superior mesenteric artery. Multiple aberrant renal arteries can pose difficulties in renal transplantation, interventional radiological and urological procedures, renal artery embolization, angioplasty, or vascular reconstruction for congenital and acquired lesions. We present a case of a left kidney supplied by the left renal artery along with superior and inferior polar arteries, arising from the aorta and inferior mesenteric artery respectively. The inferior mesenteric artery was crossed by the left ureter and inferior mesenteric vein. The superior polar artery gave rise to an inferior suprarenal artery making the variation important for clinicians and surgeons.
