Abstract We recorded a very rare case of atypical renal arteries arrangement in a guinea pig using the corrosion technique in the study of the arterial system. The right renal artery originated from the ventral wall of the abdominal aorta at the level of the caudal aspect of the 5th lumbar vertebra. The left renal artery originated from the left common iliac artery approximately 12 mm caudally to the aortic bifurcation. The right kidney was located ventral to the aortic bifurcation and the left kidney inside the pelvic cavity between the common iliac arteries. According to the vascular pattern, we determined that the ectopic kidneys in this guinea pig were unusual. This is the first case describing bilateral ectopic kidneys in a guinea pig.

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.

Iliopsoas abscesses (IPA) are uncommon, with an associated mortality rate of up to 20%. We describe the case of a 55-year-old man war veteran who presented with an unusual cause of IPA secondary to retained foreign body (FB). His initial trauma 30 years before was a result of a blast injury with shrapnel penetration suffered after inadvertently driving over a landmine as an ambulance driver in a conflict region. A CT scan was performed, revealing a 13 mmx8 mm radio-opaque FB within the right psoas at the level of the fifth lumbar vertebra with a surrounding collection. Subsequent open surgical exploration removed two gravel fragments. Given the knowledge of a traumatic blast injury with retained FB and repeated episodes of sepsis, surgical exploration is warranted. To our knowledge, this is the first case of recurrent IPA secondary to a retained FB from a historical trauma.

AbstractThe aim of this paper was to compare the level of origin of the renal arteries in the rabbit and hare. The study was carried out on ten adult rabbits and ten adult European hares using the corrosion cast technique. After the euthanasia, the vascular network was perfused with saline. Batson’s corrosion casting kit No. 17 was used as a casting medium. After polymerization of the medium, the maceration was carried out in KOH solution. We found variable levels of the origin of renal arteries in the rabbit, in the hare and between both species. In the rabbit, the right renal artery originated at the level of the second lumbar vertebra in 70 % of the cases and at the level of the first lumbar vertebra in 30 % of the cases, and the left-sided renal artery originated in 60 % of the cases at the level of the second lumbar vertebra and at the level of the third lumbar vertebra in 40 % of the cases. In the hare, the bilateral renal arteries originated at the level of the second lumbar vertebra. According to the results, it can be concluded that the origin level of the renal arteries from the abdominal aorta is more variable in the domesticated rabbit in comparison with the hare.

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.

For the present study a number of 5 female chinchilla carcasses were used. The animals were slaughtered for commercial purpuses (fur). The anatomical dissection started with the identification of the aorta (Aorta abdominalis). The next step was the intra-arterial injection of a colouring substance. The carcasses was fixed in the formaldehyde solution and subsequently the renal arteries were dissected. The first renal artery was the right renal artery (Arteria renalis dextra) and, at 0,5 cm caudally, the left renal artery (Arteria renalis sinister) arose . The origin of those arteries were disposed on the lateral part of the abdominal aorta.The origin, traject and distribution of renal arteries on the studied species have a high degree of similarity with the literature dates described for leporids.

Purpose: To quantify deformations of renal arteries and snorkel stents after snorkel endovascular aneurysm sealing (Sn-EVAS) resulting from cardiac pulsatility and respiration and compare these deformations to patients with untreated abdominal aortic aneurysms (AAA) and snorkel endovascular aneurysm repair (Sn-EVAR). Materials and Methods: Ten Sn-EVAS patients (mean age 75±6 years; 8 men) were scanned with cardiac-gated, respiration-resolved computed tomography angiography. From 3-dimensional geometric models, changes in renal artery and stent angulation and curvature due to cardiac pulsatility and respiration were quantified. Respiration-induced motions were compared with those of 16 previously reported untreated AAA patients and 11 Sn-EVAR patients. Results: Renal artery bending at the stent end was greater for respiratory vs cardiac influences (6°±7° vs −1°±2°, p<0.025). Respiration caused a 3-fold greater deformation on the left renal artery as compared with the right side. Maximum curvature change was higher for respiratory vs cardiac influences (0.49±0.29 vs 0.24±0.17 cm−1, p<0.025), and snorkel renal stents experienced similar maximum curvature change due to cardiac pulsatility and respiration (0.14±0.10 vs 0.19±0.09 cm−1, p=0.142). When comparing the 3 patient cohorts for respiratory-induced deformation, there was significant renal branch angulation in untreated AAAs, but not in Sn-EVAR or Sn-EVAS, and there was significant bending at the stent end in Sn-EVAR and Sn-EVAS. Maximum curvature change due to respiration was ~10-fold greater in Sn-EVAR and Sn-EVAS compared to untreated AAAs. Conclusion: The findings suggest that cardiac and respiratory influences may challenge the mechanical durability of snorkel stents of Sn-EVAS; similarly, however, respiration may be the primary culprit for tissue irritation, increasing the risk for stent-end thrombosis, especially in the left renal artery. The bending stiffness of snorkel stents in both the Sn-EVAR and Sn-EVAS cohorts damped renal branch angulation while it intensified bending of the artery distal to the snorkel stent. Understanding these device-to-artery interactions is critical as they may affect mechanical durability of branch stents and quality and durability of treatment.

The basis for the study was cadaver material from animals obtained during slaughter from the "Gzhelskoe Podvorye", Moscow region. Four age groups were formed. The first group included newborn animals. The sec-ond group included animals of one month. The third group included young animals of five or six months. The fourth group consist-ed of goats, starting from one year old. The age of the animals was determined according to the data obtained from monitor cards. A total of twenty heads were examined. Based on our research, primarily we established that the change in the topography of the right and left kidney in Anglo-Nubian goats exists mainly because of the displacement of the caudal end of the kidney cranially at a dis-tance equal to the length of one or two verte-brae. In both kidneys, the anterior or cranial end does not have a pronounced displace-ment. Studying kidney syntopia in goats, we found confirmation that the caudal hollow vein together with the abdominal aorta lie dorsally from the kidneys, while the rumen sac is located laterocranially from the left kidney, when it overflows, a slight change in the topography of the kidney can be visual-ized, and parts of the duodenum are located laterocranially. The data we have established confirm the similarity of the Anglo-Nubian breed of goats with goats of other breeds. By studying the vascularization of the kidneys in the Anglo-Nubian goat breed, we con-firmed that the renal blood supply is pro-duced by two renal arteries, each of which is directed to the corresponding kidney "L2-L3". We also found that the severe increase in the diameter of the renal arteries occurs in these animals from 1 to 6 months.

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

SummaryDioctophyma renale is the largest nematode that infects domestic mammals and is the aetiologic agent of a serious renal disease, dioctophymatosis. It has an indirect life cycle with carnivores serving as final hosts and earthworms as intermediate hosts. The parasite can infect humans with signifi cant zoonotic potential. The pathogenesis of dioctophymatosis is mainly associated with the extent of renal atrophy caused by the parasites, the risk of bilateral renal infestation and the location of the parasite (extrarenal cases). Clinical diagnosis is challenging, and the only treatment option is nephrectomy or nephrotomy to remove the adult nematode. A 6-year-old female crossbreed dog presented with tachypnea, tachycardia and severe hematuria, but died shortly after presentation. Postmortem examination found the right kidney was enlarged and two adult nematodes were found in the renal pelvis. The left kidney was normal. The nematodes were collected and submitted for identifi cation. The two specimens were identifi ed as D. renale using specific identifi cation keys. Herein we present the first case of renal parasitosis by the nematode D. renale in a dog from Greece. This case highlights the need for investigation of the actual prevalence of the parasite and the use of measures for the control of its expansion aiming the protection of dogs and public health.

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.
