Description
Introduction: The internal iliac artery (IIA) is a vital vascular structure that divides into an anterior and posterior division within the pelvic cavity. This branching is crucial for essential blood supply and innervation for pelvic structures and organs. Knowledge of the IIA is critical for diagnosing and managing injuries. This poster highlights a bilateral variation in the posterior branch of the IIA.
Methods: During a routine anatomy dissection of an elderly Caucasian male, a notable variation in the posterior branching pattern of the internal iliac artery was found. The variation was dissected and photographed with permission from the donor’s family and body donation.
Result: During the dissection of an elderly Caucasian male, a notable variation was identified in the branching pattern of the internal iliac artery (IIA). Bilaterally, the inferior gluteal artery (IGA) branched off the posterior division of the IIA, as opposed to the more common branching from the anterior trunk seen in over 60% of cases. This bilateral variation deviated from the standard anatomical descriptions. Photographic evidence was documented, and the findings suggest a potential variability in pelvic arterial anatomy, which could have clinical implications in procedures like embolization.
Conclusion: Understanding the variability of the inferior gluteal artery is vital for pelvic surgeries and procedures, particularly uterine artery embolization for obstetric hemorrhage. The unusual branching pattern observed in this case could influence the success of such interventions, as variations in pelvic vasculature can impact procedural outcomes. Awareness of these anatomical differences is essential for improving diagnostic accuracy and surgical approaches in the pelvic region.
