ABSTRACT
Abstract Knowledge of the anatomical variations of the visceral branches of the abdominal aorta is important information for planning any surgeries in the region. We present here a rare constellation of variations of visceral vessels around the kidneys with a brief review of the recent literature. On the right side, an accessory renal artery was observed originating just distal to the main renal artery. The middle suprarenal artery was absent on the right side and there were two inferior suprarenal arteries originating from a branch of the main right renal artery. On the left side, the testicular artery had an arched course anterior to the left renal vein mimicking an unusual variety of nutcracker phenomenon. The right kidney was drained by two renal veins into the inferior vena cava. Knowledge of the coexistence of such complex anatomical variations might be helpful for clinicians during diagnostic and therapeutic procedures.
Resumo O conhecimento das variações anatômicas dos ramos viscerais da aorta abdominal é uma informação importante para o planejamento de qualquer cirurgia nessa região. Neste relato, apresentamos um raro conjunto de variações de vasos viscerais ao redor dos rins, bem como uma breve revisão da literatura recente. No lado direito, foi observada uma artéria renal acessória originando-se distal à artéria renal principal. Não havia artéria suprarrenal média no lado direito, e havia duas artérias suprarrenais inferiores originando-se de um ramo da artéria renal direita. No lado esquerdo, a artéria testicular apresentava um curso arqueado anterior à veia renal esquerda, simulando uma variedade incomum do fenômeno do quebra-nozes. O rim direito era drenado por duas veias renais para a veia cava inferior. O conhecimento da coexistência de tais variações anatômicas complexas pode ser útil para os clínicos durante os procedimentos diagnósticos e terapêuticos.
ABSTRACT
Testicular artery (previously known as internal spermatic artery or also known as gonadal artery) is an artery that branches from the anterolateral part of abdominal aorta at the level of the second lumbar vertebra and supplies the blood to the testes. Anatomical variations of the testicular vessels are not frequently reported in the literature. The available data demonstrates that there is an overall decrease in the number of cadaver studies published in the literature. The current case demonstrates a unique variation where the right testicular artery began as a common trunk with superior polar, inferior phrenic, capsular arteries and then had an unusual course covering the surface of the kidney. The left testicular artery, had a high origin from the aorta and also descended in an oblique course, covering the kidney. The current case is important because of its implications in renal transplantation, renal and adrenal surgery, vascular surgery, oncological surgery and other disciplines.
ABSTRACT
Surgeons should have a thorough knowledge regarding the morphologic variations of the testicular arteries as any injury to this artery during surgery might cause testicular atrophy. We report in here an unusual course of left testicular artery and discuss its embryological basis and its clinical implications. The left testicular artery had a high origin from the anterior aspect of the abdominal aorta at the level of origin of renal artery. In its further course, the left testicular artery passed through a hiatus present in the left renal vein. This unusual course of the testicular artery through the vascular hiatus might lead to its entrapment and is worth reporting in efforts to educate clinicians involved in abdominal and urogenital surgical procedures.

Resumen: Introducción: El aneurisma de la arteria testicular es poco frecuente; el término se describe como la dilatación de cualquier vaso sanguíneo en el cuerpo. Caso clínico: Se presenta el caso de un paciente de 15 años con un aneurisma de la arteria testicular izquierda sin ningún antecedente de importancia familiar ni personal, quien se presentó a consulta por aumento de volumen en la región inguinal de larga evolución, acompañado de dolor esporádico y sin más síntomas. Se diagnosticó hernia inguinal y se procedió a cirugía. El diagnóstico se realizó de manera posoperatoria por medio de estudio histopatológico. En este caso, se destaca la presentación de un aneurisma verdadero de la arteria testicular y el resultado después del tratamiento quirúrgico definitivo. Conclusiones: La etiología del aneurisma y del pseudoaneurisma reportada en la literatura se describe posterior a un traumatismo testicular, y en pocos casos de origen congénito. Las manifestaciones clínicas pueden ser dolor y una masa inguinal, y muchas de las veces pueden confundirse con hernias inguinales o ser una patología agregada, por lo que el abordaje de los pacientes con patología inguinal o testicular debe ser protocolizado e incluir el aneurisma dentro de los diagnósticos diferenciales.
Abstract: Background: Aneurysm of the testicular artery is a rare entity; the term is described as the dilation of any blood vessel in the body. Case report: An 18-year-old patient with a left testicular artery aneurysm, with no family or personal history of medical importance, presented for consultation due to a volume increase of long evolution in the inguinal region, accompanied by sporadic pain with no other symptoms. The testicular artery aneurysm was not detectable preoperatively by ultrasound, which only reported data compatible with left inguinal hernia and varicocele. The diagnosis was made postoperatively by a histopathological study. This case highlights the presentation of a true aneurysm of the testicular artery and the result after definitive surgical treatment. Conclusions: The etiology of the aneurysm and pseudoaneurysm reported in the literature is described after a testicular trauma and, a few cases of congenital origin. The clinical manifestations are pain and an inguinal mass, which can be frequently confused with inguinal hernias or an aggregated pathology. Therefore, the approach of patients with inguinal or testicular pathology should be protocolized and include aneurysm within the differential diagnoses.

Background: A sound knowledge of variations of blood vessels is required during operative, diagnostic andendovascular procedures in the abdomen and pelvis. The anatomy of the gonadal vessels has assumed moreimportance with development of newer intra-abdominal operative and laparoscopic techniques. The main aimof this study is to highlight incidence of variable origin of gonadal artery and its clinical significance.Materials and Methods: Dissection of posterior abdominal wall was done in 30 cadavers in the department ofAnatomy, K.P.C. Medical College and Hospital, Kolkata to observe the origin and course of gonadal arteries.Results: Variation was found in two cases (6.67%). Both of the cases were in male (8.33%) and on the left side.Conclusion: Various morphological anomalies of gonadal arteries are reported. The possible embryologicalbasis for this variation as well as its clinical significance, are discussed. The knowledge of this variation willhelp the radiologists and surgeons in avoiding clinical complications during uroradiologic interventions andsurgical procedures such as renal and gonadal surgeries.
ABSTRACT
OBJECTIVE:To investigate clinical effects of aescuven forte combined with routine drugs in the treatment of vari-cocele(VC). METHODS:A total of 86 patients with VC selected from our hospital during Feb. 2015-Jan. 2016 were divided into control group and observation group according to odd and even number,with 43 cases in each group. Control group was given rou-tine drug therapy. Observation group was additionally given Aescuven forte tablet 300 mg,po,bid,on the basis of control group. Treatment course of 2 groups lasted for 3 months. Clinical efficacies as well as testicular artery blood flow parameters,seminal plas-ma lab indexes and semen quality were compared between 2 groups. The occurrence of ADR was also compared between 2 groups. RESULTS:Total response rate of observation group was 90.70％,which was significantly higher than 72.09％ of control group, with statistical significance (P0.05). Compared to before treatment,testicular artery peak systolic velocity,resistance index and pulsatility index of 2 groups were decreased significantly after treatment,while plasma α-glucosidase,acid phosphatase,Fructose,sperm activate rate of for-ward movement,total sperm activate rate and sperm density were increased significantly;each index of observation group was bet-ter than that of control group,with statistical significance(P0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Aescuven forte combined with routine drug therapy help to improve testicular artery blood flow status of VC patients,regulate the content of semi-nal plasma related molecules and improve semen quality so as to improve clinical efficacy with good safety.
ABSTRACT
To investigate the clinic value of microsurgical shunt for the treatment of varicocele combined with asthenspermia,the clinical data and therapeutic method for 3 patients,who conducted the microscope spermatic vein high ligation combined with superficial epigastric vein flow,were retrospectively analyzed.No postoperative complications were found,and the original symptoms and signs were disappeared.All patients were conducted scrotal ultrasound and semen routine after 3 months,and all indexes,including maximum internal diameter of the cord vein (erect position),sperm density,sperm survival rate,sperm deformity rate and sperm forward movement rate,were gradually improved.Consequently,high ligation of spermatic vein combined with vascular bypass surgery under the microscope can block the countercurrent venous blood and establish a new return channel to the testis.Meanwhile,it can also protect the testicular artery and lymph-vessel.It is worth to be spread for the treatment ofvaricocele combined with asthenospermia.
ABSTRACT
Abstract Background Knowledge of testicular artery variations is vital to ensure that they are not neglected during a variety of different operative techniques, since damage can cause testicular atrophy. Objectives The present study was therefore intended to identify variants in the origin and course of the testicular arteries. An attempt was made to classify the arteries based on their various origins. Methods This study examined 42 formalin-fixed cadavers of 40 to 70-year-old adult males. Variant origins of the testicular artery were identified and classified. Variations in the origin and course of the artery were colored, photographed, and documented. The distances between the origins of the testicular arteries and the mid-points of the origins of the renal arteries were measured. Results Testicular arteries were classified into four categories on the basis of origin. This variability was defined in relation to the renal and inferior mesenteric arteries. The mean distance between the origin of the testicular artery and the mid-point of the origin of the renal artery were 3.08 and 3.47 cm, on the right and left sides respectively. Variations were almost exclusively found on the left side. The variations observed included multiple arterial twigs forming the testicular artery, suprarenal arteries arising from the testicular artery, and testicular artery duplication. Conclusion This study provides an insight into variations in the testicular artery and proposes a classification which could help surgeons during a variety of procedures on the male abdomen and pelvis.

Objetivos Este estudo teve como objetivo identificar variações na origem e no trajeto das artérias testiculares. Foi feita uma tentativa de classificar as artérias com base em suas diferentes origens. Métodos Este estudo examinou 42 cadáveres de adultos do sexo masculino com idade entre 40 e 70 anos preservados em formol. As diferentes origens da artéria testicular foram identificadas e classificadas. Variações na origem e no trajeto da artérias foram coloridas, fotografadas e documentadas. Foram medidas as distâncias entre a origem das artérias testiculares e o ponto médio da origem das artérias renais. Resultados As artérias testiculares foram classificadas em quatro categorias com base em sua origem. Essa variabilidade foi definida com relação às artérias renal e mesentérica inferior. A distância média entre a origem da artéria testicular e o ponto médio da origem da artéria renal foi de 3,08 e 3,47 cm nos lados direito e esquerdo, respectivamente. As variações foram encontradas quase exclusivamente no lado esquerdo. As variações observadas incluíram múltiplos ramúsculos formando a artéria testicular, artérias suprarrenais surgindo a partir da artéria testicular, e duplicação da artéria testicular. Conclusão Este estudo traz informações sobre variações da artéria testicular e propõe uma classificação que poderia ajudar os cirurgiões durante diferentes procedimentos realizados no abdome e na pelve de pacientes do sexo masculino.

Normalmente las arterias testiculares surgen de la aorta abdominal, aunque hay reportes acerca de variaciones en su origen. También es un hallazgo común dos arterias renales (derecha e izquierda) derivadas de la aorta abdominal que suministran irrigación al respectivo riñón de cada lado, y actualmente la literatura reporta gran variabilidad en el número de arterias renales. Durante una disección de rutina en un cadáver masculino de 65 años de edad se encontraron múltiples variaciones anatómicas bilaterales de vasos testiculares y renales. Las variaciones encontradas fueron: presencia bilateral de tres arterias renales y tres venas renales, vena renal izquierda retro-aórtica, terminación de la vena frénica inferior izquierda en la vena renal izquierda, doble arteria testicular izquierda y doble arteria testicular derecha, todas originándose desde arterias renales accesorias. Las variaciones descritas aquí son únicas, no conocidas, ya que es el primer caso reportado hasta ahora en la literatura disponible y proporcionan una información significativa a radiólogos, endocrinólogos, especialistas en fertilidad, urólogos y cirujanos, en la determinación de la viabilidad de intervenciones quirúrgicas libres de complicación en esta región, así como el manejo postoperatorio.
Testicular arteries normally arise from the abdominal aorta. There are reports about of variations in the origin. It is also a common finding two (right and left) derived renal arteries of the abdominal aorta to the respective supplying irrigation kidney from each side, current literature report great variability in the number of renal arteries. Multiple anatomical variations bilateral of testicular vessels and renal were found during routine dissection in a 65-year-old male cadaver. The variations found were: bilateral presence of three renal arteries and three renal veins, left renal vein retro-aortic, termination of the left inferior phrenic vein into the left renal vein, double left testicular artery and double right testicular artery all originating from accessory renal arteries. The variations described here are unique is not known since it is the first case reported so far in the available literature and provide significant informations to radiologists, endocrinologists, fertility specialists, urologists and surgeons, in determining the feasibility of complication-free surgical interventions in this region as well as the post-operative management.
ABSTRACT
Origin of the Testicular Artery variations were found during routine dissection of abdomen of the middle aged cadaver in the Dept of Anatomy, Govt. Medical College Jammu. On the left side there were two renal arteries, One of them was the main Renal artery which was originating from the anterolateral aspect of abdominal aorta and running to the hilum of the kidney in front of the renal vein The other was the Accessory Renal artery which was originating from anterolateral aspect of aorta 5mm above origin of main renal artery and going to the upper pole of the kidney. The origin of accessory renal artery and main renal artery was 4.2 and 9.2mm below the level of origin of superior mesentric artery. The left testicular artery was originating from the accessory renal artery and crossing the renal artery and the renal vein anteriorly before following its usual course in the posterior abdominal wall. Only one renal artery was seen on the right side arising from the anterolateral aspect of aorta. The right testicular artery originated 52mm below the origin of right renal artery and followed its normal course This anomaly is explained by embryological development of both kidneys and gonads from intermediate mesoderm of mesonephric crest. Further the vasculature of kidneys and gonads is derived from lateral mesonephric branches of dorsal aorta .Even though the condition presents as a silent renal anomaly (Undiagnosed throughout life and revealed only on autopsy) the surgical implications are noteworthy, which too have been highlighted in this report.
ABSTRACT
The variation in origin of the testicular artery is not uncommon, few reports about a high origin from the abdominal aorta exist in the literature. The renal artery is known to exhibit variations in its number and position. The knowledge of this variation will help the radiologists and surgeons in avoiding clinical complication during interventions. During routine dissection teaching to first year MBBS students at Sapthagiri Medical College, Bangalore we found variation in vascular pattern of testicular and renal artery associated with renal cyst. Photographs of the variations were taken. There was high origin of left testicular artery and accessory left renal artery associated with bilateral simple renal cyst in adult Male cadaver aged around 60years.There was also prehilar division of right renal artery associated with renal cyst. Anomalies in the origin, course and number of testicular artery were observed in 4.7 percent of cases. Additional renal vessels are known as the accessory renal artery and their incidence varies between 9-76%. In the present case there was high origin of left testicular artery associated with accessory renal artery and renal cyst. This anatomical knowledge of the presence of accessory renal artery and high origin of testicular artery in this case is important for radiologists, surgeons and urologist in their clinical practice.
ABSTRACT
During routine dissection of a 42 year old male Indian cadaver posterior abdominal wall, variations in the testicular vessels were observed. The right testicular artery arose from the right accessory renal artery, which originated from the ventral aspect of the abdominal aorta. The left testicular artery originated from the ventral aspect of the aorta in almost the same horizontal line as the right accessory renal artery, just below the superior mesenteric artery and 1.79 cm, above the origin of the renal arteries. The right vein drained into the right accessory renal vein instead of the inferior vena cava, while the left testicular vein drained into the left renal vein. The presence of variation of both the testicular arteries as well as the testicular vein is seldom seen together.
Durante una disección de rutina de un cadáver, perteneciente a un hombre indio de 42 años, se observaron variaciones en los vasos testiculares en la pared abdominal posterior. La arteria testicular derecha se originó desde la arteria renal accesoria, proveniente de la cara ventral de la parte abdominal de la aorta. La arteria testicular izquierda se originó en la cara ventral de la parte abdominal de la aorta, casi en la misma línea horizontal de la arteria renal accesoria derecha, justo distal a la arteria mesentérica superior y 1,79 cm sobre el origen de las arterias renales. La vena renal derecha drenaba en la vena renal accesoria en lugar de la vena cava inferior, mientras que la vena testicular izquierda drenaba en la vena renal izquierda. En muy pocas ocasiones es posible observar de manera conjunta, variaciones tanto de las arterias como de las venas testiculares.

The gonadal arteries, lateral branches of the abdominal aorta, usually arise distal to the renal vessels. Knowledge of the origin and course of them, particularly their relationships with renal vessels, are important for uncomplicated surgical procedures on the posterior abdominal wall. So the relationship of the testicular artery and renal vessels were studied in 80 cadavers in Calcutta National Medical College, India and detected three rare variations. We have discussed the possible clinical implications and embryological explanation with review of literature of those variations.
Las arterias gonadales, ramas laterales de la aorta abdominal, usualmente surgen distales a los vasos renales. El conocimiento del origen y trayecto de estas, particularmente sus relaciones con los vasos renales, son importantes para procedimientos quirúrgicos sin complicaciones en la pared posterior del abdomen. La relación de la arteria testicular y los vasos renales fueron estudiados en 80 cadáveres en la Escuela Nacional de Medicina de Calcuta, India y se detectaron tres variaciones raras. Se discuten las posibles implicancias clínicas y explicaciones embriológicas, con la revisión de la literatura de estas variaciones.
