Context: The kidney is a highly vascular organ in the human body. The aim of the present study was to see the variations in perihilar branching pattern and morphology of the main renal arteries in a Bangladeshi population based on autopsy.Methods: This cross-sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2008 to June 2009, based on collection of 140 post mortem human kidneys from 70 unclaimed dead bodies which were in the morgue. All the samples were divided into three age-groups: A (10-19 years), B (20-39 years) and C (40-59 years). Morphological examination was done to identify main renal arteries and accessory renal arteries with their sites of origin and perihilar branching pattern of the renal arteries as well. The length of the renal artery was measured by using a measuring tape. Besides, renal angiography was done to see the intrarenal branching pattern.Results: The length of the right and left renal arteries were found 3.09±0.08 cm and 2.09±0.09 cm; 3.48±0.17 cm and 2.34±0.17 cm; 3.88±0.17 cm and 2.81±0.16 cm in group A, B and C respectively. The length of the right renal artery was found greater than of the left (P<0.001) in all age-groups. Besides, age related changes were also found in the length of the renal arteries (P<0.001). Accessory renal arteries were present in the right side in 33.4%, 23.35 and 33.3% specimens in group A, B and C respectively, while in the left side, in 59.7%, 27.9% and 13.4% in group A, B and C respectively. The number of anterior divisions of the both renal arteries were 2 in 8.3%, 3 in 12.5% and 4 in 79.2% specimens in group A, while in group B, 2 in 7%, 3 in 17.4% and 4 in 75.6% specimens, and in group C, 2 in 3.3%, 3 in 3.3% and 4 in 93.3% specimens. Number of posterior division was found only 1 in all the groups. Renal angiography revealed intrarenal branching pattern which showed segmental arteries divided into several lobar arteries and interlobar arteries.J Dhaka Medical College, Vol. 24, No.1, April, 2015, Page 12-16

Background: The abdominal aorta and its main branches, such as the celiac trunk and the renal arteries are manipulated during various radiologic, surgical, and oncologic procedures. This study aimed at evaluating the anatomical pattern of these vessels to assist surgeons and radiologists reduce the risk of intra- as well as postoperative complications. Methods: A retrospective analysis of 536 Computed Tomography Angiography (CTA) studies of living potential kidney donors was conducted from January 2012 to December 2018. Results: The anatomical variations of the celiac trunk was found in 9.5% of the cases. Among these cases, the most frequent variation was the Left Gastric Artery (LGA) as the first branch of the celiac trunk (80.4% of the cases). Gender was not overall significantly associated with the variations of the celiac trunk (P=0.670); however, there was a significant correlation between male gender and the most prevalent form of the celiac trunk variation (P=0.004). Variations of the renal artery occurred in 22.94% of the cases, with the left accessory renal artery being the most common variant (28.45% of the cases). Gender and the involved side (right/left) were not significantly related to the renal artery variations (P=1.000 & P=0.546, respectively). No concomitant variation of the celiac trunk and the renal artery was detected in our study. Conclusion: The anatomical variations of the celiac trunk and the renal arteries occur commonly; thus, the branching pattern of these arteries should be assessed prior to any procedure concerning them.

Each kidney is usually supplied by a single renal artery which is a lateral branch of abdominal aorta at the level of L1.The arteries supplying the kidneys show variation in the number, source and branching pattern which also include the presence of an accessory or additional and aberrant renal arteries. The additional renal artery towards the lower pole will cross the corresponding ureter and even cause ureteric obstruction. The segmental branches of renal and additional renal arteries are end arteries thus the accidental damage to these arteries can cause ischemia or necrosis and other pathological conditions. The main objective of this study was to note the variations of the arteries supplying the kidneys. An observational study was conducted on thirty kidneys of fifteen cadavers which included the kidneys of both sides. The study was conducted in Department of Anatomy of Nepal Medical College Teaching Hospital during the period between July 2018 to June 2019 and the variations were recorded as (a) single main renal arteries were found in 80% specimens on both sides (b) early division of main renal arteries were found in 16.66 % on both sides (c) origin of main renal arteries were at higher level on left side in 16.66 % (d) presence of additional renal arteries were found in 20% on both sides. This study will be helpful to cryosurgeons and also to radiologists performing various interventional radiological procedures.

Accessory Renal Arteries

In comparison with other organs, variants of blood supply to the kidneys were always at special attention due to end arteries. Anatomic variations in the renal vasculature are common and occurrence is varying in between 25% to 40%. The most common variation is presence of accessory renal arteries. Accessory renal artery generally diagnosed on abdomen angiography studies or cadaveric dissection. Only few studies or case report of intrauterine detection of accessory renal artery are available in printed and online literature. During a dedicated anomaly scan of 23 week foetus, detection of an accessory renal artery on left side entering kidney in inferior pole courses parallel to main renal arteries and arising from abdominal aorta. Knowledge of the possible anatomic variations and anomalies of the renal arteries like accessory renal arteries are necessary for proper surgical management during renal transplantation, abdominal aorta aneurysm repair, different urological procedures and angiographic procedures. As the various type of vascular and non - vascular interventions increase, knowledge of the different type of variations of the renal arteries is necessary for proper surgical management in the different specialties.

Objective. To assess the correlation between renal artery anatomy and blood pressure in Undiagnosed Hypertension and Diagnosed Hypertension. Methods. The renal artery CT scanning imaging data and laboratory data of 3000 inpatients and outpatients were collected retrospectively in 4 centers of China. Morphometric parameters were assessed using the quantitative vascular analysis (unit: mM). Results. 687 cases (23.2%) had accessory renal arteries unilaterally, and 216 cases (7.3%) had bilateral accessory renal arteries, including left kidney 825 (27.9%) and right kidney 798 (27.0%). The presence of accessory renal arteries and renal artery branches was higher in the diagnosed hypertension group as compared with the undiagnosed hypertension group (MARB, p p < 0.001; ARA, p  < 0.001; others, p  < 0.001). Consequently, multivariate regression analysis showed that age (OR = 2.519 (95% CI: 0.990–6.411, p  < 0.001)), dyslipidemia (OR = 1.187 (95% CI: 0.960–1.454, p  = 0.007)), renal hilum Outside the main renal artery branch (MRAB) (OR = 2.069 (95% CI: 1.614–2.524, p  = 0.002)), and accessory renal artery (ARA) (OR = 2.071 (95% CI: 1.614–2.634, p  = 0.001)) were risk factors of hypertension. In addition, higher renin activity was associated with ARA patients (2.19 ± 2.91 vs. 1.75 ± 2.85, p  < 0.001). Conclusions. When comparing renal arteries side by side, the anatomical length of the renal arteries is significantly different. In addition, the prevalence of accessory renal arteries and renal artery branches is higher in the hypertension group. The auxiliary renal artery and the main renal artery branch outside the renal portal are independent factors of hypertension. Renal sympathetic nerve activity is affected by renin activity and is related to the accessory renal artery.

The variations in origin of renal arteries are very common. During routine dissection of a male cadaver we found left accessory renal artery. The origin of accessory renal artery is immediately below main renal artery. The left inferior accessory renal arteries run towards inferior pole of left kidney, in the area where the left renal vein was leaving the left kidney. The vascular variations are very important for vascular surgeons, urologists, nephrologists, radiologists. DOI: http://dx.doi.org/10.3126/jcmsn.v7i1.5976 JCMSN 2011; 7(1): 65-68

The objectives of this study were to determine the level of origin of the renal artery on both sides of the body, to describe its course and branching pattern on both sides, and to detect the Supernumerary renal arteries (SRA) and their course. Both cadaveric and radiological descriptive studies were conducted from July 2015 to July 2016.The morphology and variations of the renal arteries were documented in 50 formalin fixed cadavers that were dissected in different faculties of medicine in Khartoum state. This was followed by assessment of 150 computerized tomography angiographies of the renal transplant donors who presented to three major transplant centers in Khartoum in the period between 2012 and 2015.The most common vertebral level of origin off the aorta was between the first and second lumbar segments. A supernumerary renal artery was detected in 25.5% and it was the most common anatomical variation. This was followed by early prehilar bifurcation in 6.5%. Supernumerary renal arteries were commonly hilar and lower polar, and they were more frequent in males. Bilateral supernumerary arteries were found in 4% of cases. The most common anatomical variation of the renal artery was supernumerary renal artery.Keywords: Renal artery, supernumerary, anatomical variations
