Abstract:
During the anatomical dissection of the pelvis, a duplication of the uterine artery was identified unilaterally on the left side in a 59-year-old Korean female cadaver. The first uterine artery was found to arise directly from the anterior division of the internal iliac artery and supply the upper uterine body and tube. The second uterine artery shared a common stem with the superior and inferior vesical arteries, supplying the lower uterine body. The external diameter of each uterine artery at its origin on the left side was smaller than that of the right uterine artery. One vaginal artery was identified to arise from the left internal pudendal artery. Embryologically, a duplicated uterine artery could imply the presence of two primordial arteries separately supplying the cranial and caudal parts of the Müllerian duct during the early fetal period. This case of variational anatomy is noteworthy: clinicians could elucidate it and successfully perform uterine artery embolization or hysterectomy with minimal complications.
