Bilateral low origin of testicular artery: a case report / Origem bilateral baixa de artéria testicular: relato de caso

The testicular artery is frequently subjected to radiographic imaging techniques such as angiography for diagnosis and treatment of conditions like epididymitis, testicular torsion, tumor, hematoma, and hydrocele and in cases of undescended testis. Radiologists and surgeons should therefore be aware of testicular artery variants. Although there are numerous studies and case reports that mention testicular artery variants, this is probably the first case, reporting a bilateral low origin of the testicular artery and discussing its probable embryological etiology

A artéria testicular é frequentemente examinada por técnicas de imagem como angiografia, para o diagnóstico e tratamento de condições como epididimite, torsão testicular, tumor, hematoma e hidrocele, e também em casos de criptorquidia. Sendo assim, radiologistas e cirurgiões devem estar cientes de variantes anatômicas da artéria testicular. Embora numerosos estudos e relatos de caso mencionem variantes da artéria testicular, este provavelmente é o primeiro caso a descrever origem bilateral baixa da artéria testicular e a discutir sua provável etiologia embriológica

Absence of the celiac trunk and trifurcation of the common hepatic artery: a case report / Ausência de tronco celíaco e trifurcação da artéria hepática comum: relato de caso

Abstract Anatomical variations of the celiac trunk and its branches are particularly important from a surgical perspective due to their relationships with surrounding structures. We report here a particularly rare variant involving absence of the celiac trunk in association with trifurcation of the common hepatic artery. These variations were found in an adult male cadaver. We perform a review of the literature and discuss the clinical and embryological significance of these variations. Recognition of celiac trunk and hepatic artery variations is of utmost importance to surgeons and radiologists because multiple variations can lead to undue complications.

Resumo As variações anatômicas do tronco celíaco e seus ramos são particularmente importantes do ponto de vista cirúrgico devido a sua relação com as estruturas adjacentes. Nós descrevemos aqui uma variante particularmente rara envolvendo ausência do tronco celíaco associada a trifurcação da artéria hepática comum. Essas variações foram observadas no cadáver de um adulto do sexo masculino. Neste artigo revisamos a literatura e discutimos a significância clínica e embriológica dessas variações. O reconhecimento das variações do tronco celíaco e da artéria hepática é extremamente importante para cirurgiões e radiologistas uma vez que variações múltiplas podem levar a complicações inesperadas.

Arterial glomerulus at the hilum of the right kidney and the abnormal course of the right testicular artery: a case report

Variations in the origin of arteries in the abdomen are very common. With the invention of new operative techniques within the abdomen cavity, the anatomy of abdominal vessels has assumed a great deal of clinical importance. We report here a rare case of formation of an "arterial glomerulus" at the hilum of the right kidney by the branches of right renal artery. There were 2 renal veins; a superficial and a deep. The deep vein had a peculiar course through the arterial glomerulus. The right testicular vein drained into the deep renal vein. We also observed a variant origin and course of right testicular artery. Prior knowledge of unusual branching pattern of renal vessels is necessary in the surgical interventions which require hilar dissection. Similarly, abnormal origin or course of testicular artery becomes apparent during surgical procedures like varicocele and undescended testes. Therefore, knowledge of such an anomaly in the testicular artery helps to avoid iatrogenic injuries during radiological or surgical procedures
