Numerical anomalies of renal arteries are frequently encountered at radiological investigations. Origin of main renal artery from abdominal aorta above the level of origin of celiac trunk and supplying normally positioned kidney is encountered occasionally. But ectopic supradiaphragmatic thoracic origin of main renal artery supplying a normally positioned kidney is extremely rare and reported only as case reports and till recently only ten such cases have been reported. Incidentally all cases reporting thoracic origin are right renal arteries. The present case report is an incidental observation of origin of main right renal artery from thoracic aorta at the level of upper part of body of T-12 vertebra in a male patient undergoing contrast enhanced CT for suspected lung pathology. The normally positioned right kidney was supplied by an accessory renal artery arising just below the level of origin of superior mesenteric artery. Our literature search has yielded 23 cases (excluding the present case) out of which 19 were thoracic right renal arteries and 4 thoracic left renal arteries. Additionally the present case was associated with the presence of variations of celiac and superior mesenteric arteries in the form of gastrosplenic and hepatomesenteric trunks. This association of variant gastrosplenic and hepatomesenteric trunks with thoracic origin of main renal artery is reported for the first time. Knowledge of such rare variations is crucial for radiologists, surgeons and urologists for better outcome of surgical and interventional procedures. KEY WORDS: Thoracic renal artery, Supradiaphragmatic renal artery, Ectopic renal artery origin, Hepatomesenteric trunk, Gastrosplenic trunk.

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.

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.

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

Persistent hypertension has been produced in the goat and sheep by constriction of the main renal arteries. The presence or absence of accompanying uremia depends upon the degree of constriction of the renal arteries. In both sheep and goat, constriction of one main renal artery also caused elevation of the blood pressure which tended to persist longer than in the dog. Excision of the one kidney with main renal artery constricted resulted in a prompt (24 hours) return of the blood pressure to normal. In the animals with hypertension of long duration but without renal excretory insufficiency, (the "benign" phase) no significant arterio- or arteriolosclerosis developed as a result of the hypertension alone. In the animals that had both hypertension and renal excretory insufficiency, (the "malignant" phase) the typical terminal arteriolar lesions developed in many organs. These lesions consisted of necrosis and fibrinoid degeneration of arterioles and necrotizing arteriolitis which should not be confused with arteriolosclerosis. The same humoral mechanism which is responsible for experimental renal hypertension in the dog and other animals also obtains in the pathogenesis of experimental renal hypertension in the sheep and goat.

Background. Renovascular hypertension (RVH) is an elevated blood pressure caused by partial or complete occlusion of one or both renal arteries or their branches. According to different studies, renal artery stenosis accounts for 5–10% of all cases of hypertension in children. The most common causes of renal artery stenosis are deemed to be atherosclerosis and fibromuscular dysplasia.Case description. The article describes clinical case of a newly diagnosed renovascular hypertension amid background of fibromuscular dysplasia of renal arteries in a 6-year old child, particulars of the clinical course, laboratory and instrumental methods of investigation and treatment including aortography and balloon angioplasty of renal arteries.Conclusion. This case report illustrates that in the absence of complaints and pronounced clinical symptoms the diagnosis of renovascular hypertension in a 6-year old child could not be established for a long time. Timely detection of elevated BP in children, including the young ones, not only during visiting specialist physicians but also during prophylactic examination by pediatrician, is required for early diagnosis of the disease and development of the examination and treatment strategy.

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.

The purpose of this report is to present a rare case of lumbar artery aneurysm. We report the case of a 54-years-old male patient who was misdiagnosed over years having a chronic infrarenal aortic aneurysm. A 64-slice CT at our institution revealed a large lumbar artery aneurysm. The conclusion of this case report is that a lumbar or accessory renal artery aneurysm has to be taken into consideration if there is a localized enlargement of the lower abdominal aorta and a high resolution CT-scan is strongly recommended to make the exact diagnosis.
