Takayasu`s arteritis is one of chronic inflammatory disease characteristically involving the aorta and its major branches. Symptoms and signs of the disease are various depending on the involved area. We experienced a surgical case of Takayasu`s arteritis mainly involving both renal arteries with renovascular hypertension in a 13 year old girl. Hypertension was not controlled by medical treatment including diuretics and captopril [160/140 mmHg]. Aortogram showed severely stenosed right renal artery, nearly obstructed left renal artery and not visulalized superior mesenteric artery. Angioplasty was performed for the right renal artery but aorta-renal bypass graft with greater saphenous vein was inevitable for the left renal artery. Blood pressure was controlled sufficiently with some adjunct of captopril postoperatively [130/90 mmHg]. While the patient was discharged with much improvement, she was lost follow up and died of not identified definitive cause 3 months later.

A 63 year old male had suffered from hypertension and angina pectoris for 4 years, On physical examination, blood pressure was 150/110 mmHg with medication of antihypertensive drugs. Aortogram showed the stenosis of the left renal artery, the complete occlusion of the right renal artery, and atherosclerotic change of abdominal aorta. Blood urea nitrogen was 25 mg/dl, serum creatinine was 1.2 mg/dl, and renin activity in peripheral blood was 8.7 ng /ml /hour, The stenosis of left renal artery and the complete occlusion of right renal artery should have produced the renovascular hypertension Bilateral aorto-renal bypasses with saphenous grafts were done for treatment of ren-ovascular hypertension Postoperatively, blood pressure was normalized with only small dosage of antihypertensive drugs.

Here, we present the case of a 2-month-old male infant with hyponatremic hypertensive syndrome resulting from stenosis of the right proximal and mid-renal arteries. The patient exhibited nephrotic-range proteinuria, low serum albumin, increased serum creatinine, and elevated renin and aldosterone levels. Doppler ultrasonography and computed tomography angiography revealed decreased vascular flow in the small right renal artery. Following a successful percutaneous balloon angioplasty, the patient experienced a decrease in blood pressure and normalization of serum electrolyte levels within a few days. However, it took 3 months for the proteinuria to resolve completely. This case is significant as it represents the first reported instance of a neonate presenting with clinical features resembling congenital nephrotic syndrome caused by renal artery stenosis that was successfully treated with percutaneous renal angioplasty.

Mini-pigs have been widely employed in preclinical studies to explore new therapeutic strategies for diseases of the human urinary system; however, the normal reference of the renal artery has not been clearly investigated in the mini-pig model. Therefore, we aimed to establish a normal reference of the radiological morphology of the renal artery in mini-pigs by renal angiography via catheterization of the carotid artery. The renal angiographies obtained from 15 mini-pigs were evaluated to determine the orifice from the aorta, facing direction, size and the number of branches of renal arteries. Cranio-laterally facing renal arteries with 2 distal branches were mainly observed in the renal artery of mini-pigs. Both sides of the renal artery presented symmetrical sizes; however, the right renal artery orifice from the aorta was located more cranially than the left counterpart. The results of this study will contribute to radiological diagnosis of the renal artery as well as preclinical studies of mini-pigs.

Takayasu’s disease produces the occlusive and aneurysmal lesions of major branches of the aorta. Angiography is the most important diagnostic procedure in Takayasu’s disease. Surgical treatment is often justified to avoid the possible lethal consequences of hypertension on the heart, kidney, and brain, as well as in the case of aneurysm because of its risk of rupture. We experienced one case of the Takayasu’s disease associated with abdominal coarctation and renovascular hypertension. The patient was 17 years old female and had suffered from hypertension for 14 months. On physical examination, BP was 150/100 mmHg in the right arm and 120/80 mmHg in the left arm. The pulses of the left brachial and femoral arteries were weakly palpable. Aortogram showed the stenosis of the left common and subclavian arteries, coarctation of the abdominal aorta, and stenosis of the right renal artery and complete occlusion of the left renal artery. The stenosis of the right renal artery and the occlusion of the left renal artery produced the renovascular hypertension. She underwent aorta-aortic bypass for the coarctation of the abdominal aorta and aorta-renal bypass for treatment of renovascular hypertension Postoperatively, both femoral pulses were equally palpable. On discharge, antihypertensive drugs were discontinued. She has remained normotensive for last one year.

This study was carried out to observe the direct effect of hydrocortisone on renal function by infusing it into a renal artery. Hydrocortisone (5mg/kg) or saline (0.5 ml/kg) was infused directly into the left renal artery of the rabbit, the right kidney was left intact to serve as a control for general action of acetazolamide (10 mg/kg) or aminophylline (10 mg/kg), which was administered intravenously 30 minutes after the direct infusion of pretreated drugs (hydrocortisone or saline). The changes of urine volume, pH, urinary excretion rates of $Na^+,\;K^+\;and\;Cl^-$, and the clearances of inulin and PAH were measured at an interval of 10 minutes for half an hour after the direct infusion of hydrocortisone or saline, and for one hour after intravenous administration of acetazolamide or aminophylline. The results of the experiment were as follows: 1. Significant changes in urine volume and urinary electrolytes (excreted rates of $Na^+,\;K^+\;and\;Cl^-$) were observed in the hydrocortisone-infused group 10 minutes after the administration of acetazolamide, compared with the saline-infused group. Especially, the effect was more potent on the infused (left) side than on the contralateral (right) side. 2. Significant changes in urine volume and urinary electrolytes were also observed in all the aminophylline-treated groups, but no remarkable difference was noticed between the hydrocortisone-infused group and the saline-infused group, nor between the left and right sides. 3. No signicant changes in the clearances of inulin and PAH were in the infused (left) side of all the experimental groups, as compared with the contralateral (right) side. From the above results, it is obvious that hydrocortisone infused into a renal artery exerts diuretic action when administered in combination with acetazolamide, and the mechanism of action rests not on its hemodynamic change for renal blood flow, but on the potentiation of carbonic anhydrase inhibiting action. However, the exact mode of action remains yet to be clarified.

Knowledge of variations of renal vessels is of utmost importance in retroperitoneal surgeries and kidney transplant surgeries. We report concurrent variations of the right renal vessels, observed in an adult male cadaver during dissection classes. The right kidney was supplied by three renal arteries, out of which two entered the kidney through the hilum and the other one entered through the lower pole of the kidney. There were five renal veins, emerging independently from the hilum and opening separately through five openings into the inferior vena cava. Among the veins, only one emerged anterior to the renal pelvis and the other four emerged behind it. Four of them terminated into the posterolateral aspect of the inferior vena cava, whereas one terminated into its anterior aspect. Fourth vein from above, received the right testicular vein. The renal hilum was clogged with the presence of seven vessels and renal pelvis.

Primary renal artery aneurysm has been estimated to account for an incidence of 0.015-1% with associated morbidities including renovascular hypertension and rupture. Renovascular hypertension associated renal artery aneurysms in children is not a common disease. In patients with complicated renal vascular disease, renal autotransplantation has been used as an alternative to percutaneous transluminal angioplasty, which may be hazardous in these situations. We report a case of a renal artery aneurysm in a 13-year-old Korean child presenting hypertension detected during school health examination. Preoperative workup demonstrated a $2.8{\times}2.1{\times}1.9$ cm saccular aneurysm in the right renal hilum that was not amendable to endovascular repair. A surgical strategy including extracorporeal renal artery reconstruction with autotransplantation was applied in order to restore renal artery anatomy and to treat renovascular hypertension. Immediately he complained of severe right flank pain and postoperative doppler sonography revealed lack of perfusion. On the 5th day after autotransplantation, the patient underwent a transplant nephrectomy. He was well postoperatively and was found to have a normal kidney function and stable blood pressure control without antihypertensive medication. This is the first pediatric case of renal artery aneurysm in Korea who underwent extracorporeal repair followed by autotransplantation failure. More pediatric cases with renal artery aneurysm should be reported to identify therapeutic outcome and long term prognosis.

The distribution of renal artery of fifty Korean native cattles (100 kidneys) was observed. Vinylite solution was injected into renal artery of ninety specimens for cast preparation. The angiography was prepared in 10 specimens by injecting thirty percent of barium sulfate solution into renal arteries, and then radiographed on a soft X-ray apparatus (Shimadzu Waltes 60). 1. A. renalis arose from the each side of abdominal aorta in the Korean native cattles. 2. The renal arteries were bifurcated into Ramus cranialis and caudalis (91%), and Ramus cranialis, medius and caudalis(9%) which were ramified 1-4 segmental arteries, respectively. 3. The segmental arteries were originated from R. cranialis and R. caudalis (87%), R. medius (9%) and A. renalis (4%). 4. The kidney were divided separately into 5-7 arterial segments by running of the segmental artery into the parenchyma. Among them six segments were mostly frequent(53%). 5. The Arcus arteriosus renalis was observed at 44% of the left kidney and 14% of the right kidney.
