Abstract Background and aims: Kidneys are the pair of excretory organs situated retroperitoneally in the lumbar region on either side of vertebral column. Classically there is a single renal artery supplying each kidney which arises from abdominal aorta. Understanding the anatomy of vascular pattern of kidney is important for clinicians to perform renal transplantation, interventional radiological stodies. The present stody was undertaken for studying the prehilar vascular pattern of renal artery. Material and methods: Kidneys were collected from the department of Anatomy, Navodaya Medical College and Hospital, Raichur, Karnataka. Totally 84 kidneys were collected, the kidney containing full renal arteries from aorta were selected. The abnormal shaped kidneys were excluded from the stody. The blunt dissection was done to remove fat, loose connective tissue at the hilum and the artery was coloured with fabric red colour and photographed. Results: Out of 84 kidneys, single renal artery was seen in 72 cases and 12 kidney specimens showed double renal arteries. The single renal artery divided into anterior and posterior divisions. The anterior division was classified into three types of which, type I showed 43.06% incidence, type II showed 33.33% and type III showed 23.61% incidence. The posterior division was classified into two types of which type I showed 69.44% and type II showed 30.56%. Superior polar arteries were seen in 13.09% and inferior polar artery was seen in 5.95% cases. Conclusion : A sound knowledge of branching pattern of renal artery is important for urologists and radiologists for giving proper diagnosis and treatment. The present study mainly aims for prehilar vascular pattern of renal artery which may be usefull for renal transplantation and microvascular surgeries of kidneys.

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

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.

Abstract Context: Facial artery is usually the main artery supplying the face. It gives three named branches on the face, the inferior labial, the superior labial and the lateral nasal and continues as the angular artery. Face is also supplied by the transverse facial artery and the arteries accompanying the cutaneous nerves. Aim: In the present study, variations of facial artery on face were observed. Settings & design: Department of Anatomy, Kasturba Medical College, Manipal. Material & method: The present study was performed on 38 males and 12 females' formalin-fixed hemi-faces. Diameter of facial artery was noted at two specific points using a fine microcaliper. Results: The variations were divided into 3 categories. Out of 38 male hemi-faces, 100% right and 78% left hemi-faces belonged to type I category; 22% left hemi-faces belonged to Type III category. Out of 12 female hemi-faces, 80% right and 80% left hemi-faces belonged to Type I category, 18% left hemi-faces belonged to Type II category and 20% right and 2% left hemi-faces belonged to Type III category. Premasseteric branch was observed in 4 hemi-faces; a duplex with a prominent lateral angular branch was observed in 4 hemi-faces and anenlarged transverse facial artery was seen in 2 hemi-faces. The diameter of facial artery at its origin and at the antero-inferior angle of masseter muscle was larger in males. Conclusion: This study shows that the variations in the branches and the diameter of the facial artery were relatively larger in males when compared to females.

Abstract Background & aims : Kidneys are the main excretory organs in our body. About one-fifth of the total cardiac output is supplied to the kidneys via renal arteries. This study focusses on renal artery branching pattern which is very useful for various surgical procedures. This study is done by taking a cast of vascular segments of kidney by injecting a silicone rubber into the renal arteries using RTV 116 silicone rubber. Materials and metbods : Kidney specimens from well embalmed cadavers were taken and a flowable silicone rubber is injected into the renal arteries via a cannula. Then the arteries were ligated and kept aside to solidify. Next step was to bring about degradation of the kidney tissue to leave behind the silicone rubber residue of the branching pattern by immersing the organ in KOH solution. Result: Branching pattern was observed and documented in all 20 specimens. Conclusion: Knowledge of the branching pattern of renal artery is instrumental in surgeries for it to be a success and more so in renal transplants. Thus, this study would help to provide a better picture of vascularization of the kidney along with its segmental pattern.

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.

Purpose: To report preliminary outcomes of Viabahn Balloon-Expandable Endoprosthesis (VBX) stent-graft as bridging stent for renal arteries in fenestrated endovascular aneurysm repair (FEVAR). Materials and Methods: Between 2018 and 2019, patients undergoing FEVAR at 3 referral Italian university hospitals were prospectively collected. During the study period, VBX was the first-line choice as bridging stent for renal arteries. Procedural and anatomical data were analyzed, including renal artery (RA) configuration. A dedicated software (3Mensio, Vascular Imaging, Bilthoeven, The Netherlands) was used and RA anatomy classified as follow: upward-oriented in case of any angle >30° above the horizontal or transverse axis perpendicular to the aortic axis, downward-oriented if there was an angle >30° measured below the transverse axis and downward + upward in case of an angle <30° associated with a renal artery angulation >90°. Primary endpoints were technical success, defined as complete deployment of the fenestrated endograft without target vessel (TV) loss, limb stenosis or occlusion and type I or III endoleak, and freedom from target artery instability (TAI), defined by target vessel-related death, occlusion, rupture or reintervention for stenosis, endoleak or disconnection. Secondary endpoints were target artery patency rate and freedom from reinterventions. Results: A total of 26 elective FEVAR for juxta/pararenal aneurysm (20), thoracoabdominal type II (3) and type IV (3) were included. Fifty-one RA were planned for revascularization. Of these, 32 were downward, 10 horizontal, 6 upward, 4 were downward + upward. Technical success was achieved in 88.5% (23/26) of patients and 94.2% (48/51) of the TVs. One occlusion (2.1%) occurred within 30 days in a patient with previous endovascular aortic repair and suprarenal fixation. During follow-up (median 10 months), there was 1 type IC endoleak after 6 months (2.1%) in a patient with upward plus downward arterial orientation. Freedom from TAI was 96.1% (CI = 0.89 to 1.04) at first month and 92.3% (CI = 0.82 to 1.03) at 6 months. No aneurysm-related mortality and renal insufficiency occurred during follow-up. Conclusion: The use of VBX as bridging stent of RA in FEVAR is safe and feasible. Previous EVAR and tortuosity of RA may be a challenging on target vessel fate.

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.
