Uncommon drainage of the left testicular vein: a case report

An uncommon drainage of the left testicular vein (LTV) was observed during a routine cadaver dissection, where a lateral division of the LTV was found to drain into an abdominal (anterior) tributary of the second lumbar vein. Adequate knowledge of the LTV anatomical variation presents clinical importance in renal transplantation, renal and testicular vein surgeries, testicular color Doppler imaging, testicular venography, and others retroperitoneal therapeutic and diagnostic procedures. Therefore, surgeons, especially those who work in the retroperitoneal space, must be aware of left testicular vein abnormalities, which may be encountered during surgery

Rare variation of the right internal jugular vein: a case study.

This study reports on a rare variation of the right internal jugular vein (IJV) identified during routine anatomic dissection of a male cadaver. The right IJV had a tributary located parallel and medially to the IJV itself. This branch of the IJV emerged between the transverse processes of the 3rd and 4th cervical vertebrae and drained into the junction between the right internal jugular and brachiocephalic veins. The present study described a rare branch of the right IJV, which is important knowledge for surgeons, in order to prevent accidental injury and bleeding during surgical procedures.

O presente estudo demonstrou uma variação rara da veia jugular interna direita (VJI), identificada durante uma dissecção de rotina de um cadáver masculino. A VJI direita apresentou uma tributária localizada paralelamente e medialmente à referida veia. Essa tributária da VJI emergiu entre os processos transversos das 3ª e 4ª vértebras cervicais e drenou para a junção entre as veias jugular interna e braquiocefálica direita. O conhecimento da variação anatômica demonstrado no presente estudo é importante para os cirurgiões, a fim de prevenir lesões acidentais e sangramento durante procedimentos cirúrgicos.
