Abstract
Variations of the testicular veins are relevant in clinical cases of varicocele and in other therapeutic and diagnostic procedures. We report herein on a unique variation of the left testicular vein observed in an adult male cadaver. The left testicular vein bifurcated to give rise to left and right branches which terminated by joining the left renal vein. There was also an oblique communication between the two branches of the left testicular vein. A slender communicating vein arose from the left branch of the left testicular vein and ascended upwards in front of the left renal vein and terminated into the left suprarenal vein. The right branch of the testicular vein received an unnamed adipose tributary from the side of the abdominal aorta. Awareness of these venous anomalies can help surgeons accurately ligate abnormal venous communications and avoid iatrogenic injuries and it is important for proper surgical management.

Resumo
Variações nas veias testiculares têm relevância em casos clínicos de varicocele e em outros procedimentos terapêuticos e diagnósticos. Relatamos aqui uma variação peculiar de veia testicular esquerda observada em um cadáver adulto do sexo masculino. A veia testicular esquerda bifurcava para dar origem aos ramos esquerdo e direito, os quais terminavam juntando-se à veia renal esquerda. Foi observada também comunicação oblíqua entre os dois ramos da veia testicular esquerda. Uma fina veia comunicante originava-se do ramo esquerdo da veia testicular esquerda e ascendia até a frente da veia renal esquerda, terminando na veia suprarrenal esquerda. O ramo direito da veia testicular recebia um tecido adiposo tributário não especificado da lateral da aorta abdominal. Conhecimento dessas anomalias venosas pode ajudar os cirurgiões a ligar corretamente comunicações venosas anormais e evitar danos iatrogênicos e é importante para um manejo cirúrgico apropriado.
