NAGABHOOSHANA, Somayaji et al. Anatomical variation of obturator vessels and its practical risk: a case report from an anatomic study. J. vasc. bras. [online]. 2008, vol.7, n.3, pp.275-277. ISSN 1677-5449.  http://dx.doi.org/10.1590/S1677-54492008000300015.

Obturator artery is frequently a branch of anterior division of the internal iliac artery. It has drawn attention of pelvic surgeons, anatomists and radiologists because of the high frequency of variations in its course and origin. The obturator vein is usually described as a tributary of the internal iliac vein. During routine dissection classes to undergraduate medical students we have observed obturator artery arising from external iliac artery, obturator vein draining into external iliac vein, communicating vein between obturator vein and external iliac vein and inferior epigastric artery arising from the obturator artery. The anomalous obturator vessels and inferior epigastric artery in the present case may be in a dangerous situation in pelvic surgeries that require dissection or suturing along the pelvic rim. Developmental reasons and clinical significances of the variations are discussed.

Palavras-chave : Obturator vessels; inferior epigastric artery; anatomical variation; complications.
