Total occlusion of the abdominal aorta is unusual, and potentially catastrophic. It occurs in patients with advanced atherosclerotic occlusive disease, and can cause severe ischemic manifestations, depending on the site of obstruction. Prompt and appropriate diagnostic and therapeutic approaches are important whenever this condition is suspected, in order to avoid a fatal outcome. The development of a complex network of collaterals may prevent the manifestation of acute ischemic phenomena, and cause a delay in diagnosis and treatment. Here we report the clinical case of a 59-year-old man who was referred to our Department for evaluation of renal failure and refractory hypertension. Ultrasonography and 99mTc-DTPA scintigraphy showed a shrunken, non-functioning left kidney, while CT angiography and aortography showed the complete occlusion of the aorta from below the right renal artery down to the bifurcation of both common iliac arteries, with a critical stenosis of the origin of the right renal artery, an occlusion of the left renal artery as well as of the origin of the inferior mesenteric artery. The patient was referred to the surgery department for aorto-bifemoral bypass surgery and re-implantation of the right renal artery.

Objectives. Renal artery stenosis, as main cause of renovascular secondary hypertension, is mainly caused by atherosclerosis of large vessels and is clinically characterized by resistant or malignant hypertension, impacting the kidney function to various degrees. The present article brings into attention the case of a patient which developed renal artery stenosis on the left kidney, the same condition occurring 12 years later on the right kidney. Material and method. Our patient was initially diagnosed at the age of 48 with complete occlusion of the left renal artery, for which left nephrectomy was performed, while the right artery was normal. Twelve years later she presents with renal artery stenosis on the right kidney, which is treat by stent-angioplasty. Results. After surgery, the patient’s evolution was positive, with amelioration of the laboratory values, in parallel to the arterial blood pressure. Discussions. The probability that, in the moment of diagnosis of renal artery stenosis with progressive evolution to occlusion caused by atherosclerosis, the other artery would be normal, both seen by ultrasonography and angiography, while years later to develop stenosis, is minimal. Up to present, the literature holds little evidence of such similar cases. Conclusions. In the particular case of patients that were diagnosed with severe renal artery stenosis of atherosclerotic origin and had only one of the arteries affected, it is necessary to keep a permanent monitoring, justified by the risk of development of the same pathology to the other artery

Aim: The use of shockwave lithotripsy for the treatment of heavily calcified atherosclerotic plaques before stenting showed great results in terms of feasibility and safety with favorable initial success. Evidence suggests that it is a useful tool to treat calcified lesions in peripheral and coronary arteries. Here, we describe the case of a patient with calcified renal artery stenosis successfully treated with the shockwave lithotripsy system. Case Report: We present a 76-year-old man with a known significant atherosclerotic renal artery stenosis and refractory hypertension. The patient received an angioplasty of the right renal artery in the first session and he was admitted for a second session to intervene in the left renal artery. The lesion was successfully treated with the lithotripsy system. Final angiography demonstrated an excellent position of the stent and good wall apposition. Conclusion: Our clinical case demonstrates that lithotripsy is safe and effective also for the treatment of the renal artery.

Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vascular structures at the hilum of the kidney in terms of their pattern of arrangement and division. The present paper describes a bilateral anomalous arrangement of the structures at the renal hilum as well as their peculiar branching pattern which is of clinical and surgical relevance. Multiple branching of the renal vessels was observed in both kidneys due to which the hila were congested. The right renal artery immediately after its origin divided into 2 branches. The upper branch represented an aberrant artery whereas the lower branch gave 5 divisions. The left renal artery also divided into 2 branches much before the hilum as anterior and posterior divisions. The anterior branch took an arched course and gave 6 branches. The posterior branch gave 3 terminal branches before entering the renal substance. In addition to anomalous hilar structures, normal architecture of both kidneys was altered and the hilum of the left kidney was found on its anterior surface.

In this study, it was aimed to investigate the arterial vascularization of the kidneys in the South Karaman sheep breed. Twelve South Karaman sheep kidneys were used in the study. The course of the renal arteries in the kidney was examined by means of dissection and corrosion cast techniques. The kidneys were vascularized with right renal artery and left renal artery to the arteries originating from the abdominal aorta. Right renal artery was seen to be slightly more prominent than the left renal artery. Left renal artery was measured longer and thicker than the right renal artery. The renal artery entering the renal hilus, dorsal and ventral part of the renal artery were detected. However, in several materials, the left renal artery was shown to have a third branch. The dorsal and ventral branches gave interlobar artery with numbers ranging from 2-5. Each interlobar artery had multiple arcuate artery. These arteries ended by giving the interlobular artery. Anastomosis was not observed between the renal arteries. Although there were some important variations in the distribution of renal arteries of South Karaman sheep, similar findings were reported in the literature.

A positive Shwartzman reaction, as indicated by thrombosis and focal hemorrhage in one or more organs, was elicited in 19 of 34 rabbits in which the preparatory injection of bacterial filtrate was made into the left renal artery and the reacting injection was made in the ear vein 24 hours later. In 24 of the 34 rabbits the kidneys were undisturbed throughout the duration of the experiment except for the intra-arterial injection of the left. In 12 of these 24 a positive Shwartzman reaction was observed in the uninjected right kidneys. In only 1 of the 24 injected left kidneys were there changes that might be construed as representing a positive Shwartzman reaction. The changes in this kidney consisted of glomerular thrombosis, not associated with hemorrhage or necrosis. The positive renal Shwartzman reactions seen in the right kidneys were similar to those reported by Apitz and Gerber as representing the renal changes occurring as part of a generalized Shwartzman reaction. The retention of the bacterial filtrate of the preparatory injection in the left kidney, by obstructing both vein and artery for 15 minutes, did not lessen the refractory state. The removal of the right kidney prior to the experiment, with the subsequent demonstration that circulation through the remaining left kidney was not impaired by the intra-arterial injection of filtrate, indicated that the refractory state of the injected kidney was not the result of failure of the reacting dose of filtrate to reach the kidney. In the unilaterally nephrectomized rabbits the development of a positive reaction in other organs indicated that the lack of reaction in the kidney represented a local refractory state. No explanation of the phenomenon was disclosed by these experiments.

Abstract Detailed extraparenhymal renal hilar dissection was performed on 110 fixed cadaveric kidneys (60 from male cadavers and 50 from female cadavers). We analyzed the number of renal arteries, angles between renal arteries and abdominal aorta, length and diameter of the renal arteries. Multiple renal arteries were present in 20.9% of cases, with a slightly higher incidence on the right side (21.8%: 20.0%). The angle between the aorta and the RRA varied from 30° to 100° with a mean of 64.1°, while the angle between the abdominal aorta and the LRA was 40° to 115°, with a mean of 67.3°. The external caliber of the RRA at the point of origin from the abdominal aorta was 5 mm to 9.1 mm, with a mean of 6.8 mm. The same caliber of the LRA was 3.7 to 9.6 mm with a mean of 7.0 mm. The average length of the renal artery from the point of origin from the abdominal aorta to the branching point was 36.2 mm for the right renal artery and 30.7 mm for the left renal artery. The average length of the renal artery from the point of origin from the abdominal aorta to the renal hilum was 65.1 mm for the right one and 54.7 mm for the left one. Knowledge of the number of renal arteries, their mode of entry into the kidney, the angles they build with the abdominal aorta, their diameter and length has practical applications in interventional radiology and surgery of the kidney and its environment.

Summary 11C-benzoic acid prepared in a radiochemical purity over 90% was studied radiopharmacologically in mice and rabbits. The uptake of 11C-benzoate in ICR mice increased quickly. The ratio of kidney uptake rate to that in other organs reached values between 9 and 55 with a maximum at 10 min after i.v. injection. Gamma camera imaging of rabbits showed that uptake in the kidneys began at 2 min after injection and that activity began to appear in the bladder 4 min later. Rabbits with left renal artery ligature showed no uptake in the left kidney but the right kidney was imaged to the same extent as that of a rabbit without artery ligature. The kidney imaging of 11C-benzoic acid may be a useful method for renal diagnosis.

Objective. The aim of this study was explored the duplicity of renal artery in a specimen of Cerdocyon thous, focusing on the possibilities of clinical-surgical implication of this anatomical variation. Materials and Methods. Were dissected 32 specimens of Cerdocyon thous, obtained from the collections of the Laboratório de Ensino e Pesquisa em Morfologia dos Animais Domésticos e Selvagens do Departamento de Anatomia Animal e Humana, da Universidade Federal Rural do Rio de Janeiro e Laboratório de Anatomia Animal da Universidade Federal do Pampa. Results. Were observed a numerical variation in the left renal artery in an adult female cadaver. The left kidney had two renal arteries, one cranial and another caudal. The first renal artery of the left kidney, measuring 2.25 cm in length, originated laterally from the abdominal aorta at the level of the third lumbar vertebra. Moreover, it emanated two pre-hilar branches, one dorsal and one ventral, with the ventral branch supplying also to the adrenal gland. The second renal artery also originated laterally from the abdominal aorta at the level of the third lumbar vertebra and measured 2.36 cm in length. It also emitted two pre-hilar branches, one cranial and another caudal, which emitted the ureteral branch. Conclusions. Numerical variations of the renal arteries should be considered in the execution of surgical, radiological and experimental procedures in order to avoid mistakes made due to lack of knowledge of the possibility these variations both in domestic and wild animals.
