Description:

Arterial blood to the human uterus is provided by a pair of uterine arteries (UA) and supported by terminal branches of ovarian (OA) and vaginal arteries (VA). Literature reports the existence of ipsilateral and contralateral anastomoses between these arteries and the UA, but data on the prevalence of such anastomoses are discrepant. The aim of this trial is to study whether contralateral and ipsilateral anastomoses exist. We studied nine human uterine specimens, which were obtained from (i) human cadavers (n = 6), (ii) uterine transplant recipients (n = 2), and (iii) one altruistic uterine donor (n = 1). We injected India ink into the graft through the UA of each specimen (n = 8) or OA (n = 1). We semiquantitatively observed and evaluated the extent of the injection on horizontal, vertical, and transmural levels. The dye permeated beyond the midline in 9/9 (100 %) cases. Nearcomplete/complete permeation to the contralateral side was observed in 6/9 (66 %) cases. The dye permeated ipsilaterally throughout all uterine levels in 8/8 cases (100 %) of UA injection. The entire wall of the myometrium was permeated in 2/9 (22 %) cases. In 7/9 (78 %) cases, the wall of the myometrium was permeated less than halfway through. In conclusions, the preliminary results of this study prove the existence of ipsilateral and contralateral anastomoses. Complete transmural injection was observed in only 22 % of cases; however, this finding does not provide information about the functional capacity of these anastomoses. More data and studies are necessary to make definitive conclusions.
