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

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.

Main Renal Artery

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.

Objectives: To determine renal artery variation in adults in a subset of Karachi population by using Multidetector Computed Tomography (MDCT) angiography. Study Design: A cross sectional study. Setting: Dr. Ziauddin Hospital, Radiology Department, Karachi. Period: From January, 2017 to June, 2017. Material & Methods: Study participants were 250 individuals, who were presented to Dr. Ziauddin hospital, Karachi, Distribution, number and morphology of renal artery variation were reported on Multidetector computed angiography (MDCTA). Renal artery variation with side of the kidney and gender were analyzed. Data was analyzed on SPSS version 20 (Statistical Package for Social Sciences). Frequencies and percentages were calculated for renal artery variations. Results: Following parameters were observed. Out of total 250 study participants single renal artery was present in 73.6 % (184) individuals and accessory renal artery was present in 26.4% (66) individuals. Accessory renal arteries (ARA) were present in 13.8% (35) individuals and 12.6% (31) individuals on respectively on right and left sides. Among accessory renal arteries superior polar arteries were present in 14.9% (37) kidneys, hilar arteries in 10.2 % (26) kidneys and inferior polar arteries in 1.3 % (3) kidney. Conclusion: A complete knowledge of renal artery variations is essential for surgeons and interventional radiologist especially during procedures such as renal vascular interventions and renal transplant. Frequency of ARA in our studied population is comparable to Asian population.

Stage Renal Disease

The use of kidney grafts with aneurysmal disease involving the renal arteries for transplantation is very uncommon and relatively controversial. We herein present the case of a 52-year-old woman who volunteered to become a living-nonrelated donor; during the preoperative imaging workup, a computed tomography angiography revealed a 1.5-cm saccular aneurysm in the left kidney, while the contralateral renal artery was normal. We decided to utilize the left kidney for a 25-year-old male patient with end-stage renal disease, and following the ex vivo repair using the recipient epigastric vessels and saphenous veins, we completed the transplantation in the right pelvic fossa. The postoperative period was uneventful, and at 8 months from the surgery, the graft remains functional. The surgical repair of renal artery aneurysms followed by immediate kidney transplantation is a safe technique and an effective replacement therapy for recipients. The incidental finding of isolated aneurysmal disease in renal arteries should not exclude graft potential availability for transplantation following repair.

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.

Renal Artery Embolization

Introduction: Renal artery embolization is a minimally invasive X-ray endovascular operation that is used in the treatment of various urological diseases. This operation is of increasing interest due to its ability to occlude not only proximal, but also distal renal vessels with a low risk of complications. Recent developments in endovascular technology make embolization one of the effective and safe methods applicable to stop renal bleeding, preoperative preparation for surgical treatment of renal malignant tumors, and first-line treatment for angiomyolipomas. For a certain category of patients, renal artery embolization is practically no alternative method of treatment. This applies to comorbid patients with kidney tumors and aggravated somatic status, in whom the anesthetic risk makes open or laparoscopic surgical treatment impossible, and embolization can reduce symptoms, improve the quality of life of such patients and prolong the patient's life.Clinical case: we demonstrate the experience of X-ray surgical treatment of cT1aN0M0 left kidney cancer in an 80-year-old patient.Conclusion: Embolization of renal arteries in some cases can be an effective and safe alternative treatment for renal cell carcinoma in somatically burdened patients who cannot perform surgical treatment.
