RESUMEN
Increased frequencies on variations in the origin, course and branching of retropubic vessels has brought an increased attention to anatomists, surgeons and radiologists. Pubic arterial supply normally originates from branches of; obturator artery before it leaves the pelvic cavity at the obturator foramen, and inferior epigastric artery. Branches from these two vessels usually anastomoses to supply the pubis. We observed a unique variation of pubic artery presenting unilaterally during a routine dissection in an 85-years-old male cadaver. A single unilateral variant left pubic artery was seen arising from a variant left obturator artery that originated from external iliac artery in a common trunk with inferior epigastric artery. On its way to the pubic region it gave a branch that provides arterial supply to the rectus sheath. To date this is a rare entity, thereby important to pelvic surgeons and radiologists undertaking routine procedures involving the retropubic space (space of Bogros).
RESUMEN
Background: Variations in formation of brachial plexus roots, trunks, divisions and cords are not uncommon and maybe of important in regional anaesthesia involving the upper limb. However, in the present case we are reporting a rare bilateral multiple variations observed during routine dissection on a 77-years-old embalmed male cadaver on left and right brachial plexus. Understanding the anatomical variations involving brachial plexus is important and might benefit the physicians, surgeons, anaesthesiologists and neuroanatomists during their routine procedures involving the cervical, axillary and the upper limb regions.
