Ramification Pattern of the Arteries Supplying the Rabbit Female Genital Organs

Abstract

Uterine adenocarcinoma occurs in more than 60% of female rabbits aged 4 years and over. To cure or prevent this uterine disorder, ovariohysterectomy should be performed. Although knowledge of the arterial supply to the ovary, uterus, and vagina is required, few studies have described the arterial anatomy. Therefore, we dissected ovarian, uterine, and vaginal arteries in 15 New Zealand White and 15 Japanese White rabbits to clarify the anatomy. The ovarian artery arose from the abdominal aorta, and in 50% of cases, the left artery emerged more cranially than the right artery. The ovarian artery provided the ovarian, uterine, and tubal branches with three branching types. The most frequent type (67% of the halves on the right and 63% of the halves on the left) exhibited three branches that independently arose from the ovarian artery. The uterine artery usually originated from the umbilical artery, with its ramification pattern divided into two types, having one or two uterine arteries, respectively. The most frequent type (all halves on the right and 83% of the halves on the left) had one uterine artery that originated from the umbilical artery. We observed three types of vaginal artery origins, with the branching type where the vaginal artery arose from the internal iliac artery being the most frequent (97% of the halves on the right and 90% of the halves on the left). The detailed arterial supply pattern of the rabbit female genital organs determined in the present study will be helpful when performing rabbit gynecological surgeries.

Ovarian, uterine, and luteal vascular perfusions during follicular and luteal phases in the adult cyclic female rabbits with special orientation to their histological detection of hormone receptor

“…The right OA emanated before the left one from the abdominal aorta, which was verified in rabbits [43], and chinchilla [44]. Our finding asserted that the OA releases uterine, tubal, and ovarian branches, which was confirmed by Kigata and Shibata [45]; however, this is inconsistent with the finding of Milanović et al [43]. Therefore, the OA is responsible for ovarian, oviduct, ovarian bursa, and uterine horn nutrition in rabbits [43], and bitch [46].…”

“…Therefore, the OA is responsible for ovarian, oviduct, ovarian bursa, and uterine horn nutrition in rabbits [43], and bitch [46]. The UA originated from the common iliac artery, which was inconsistent with the findings of Kigata and Shibata [45], who asserted that it emanated from the umbilical or common iliac artery. The UA is ramified to provide vaginal, cranial vesicular artery, and uterine branches, which is consistent with the findings of Kigata and Shibata [45].…”

Comparison of the Vasoconstriction Effect of Phenylephrine and Ephedrine on the Uterine Arteries of Pregnant Rabbits: A CT Imaging-Based Study

“…In this study, we rst attempted to visualize and identify the uterine artery under CT. According to published data [19,20] , the uterine artery of female rabbits originates from the umbilical artery, which stems from the external iliac artery, a branch of the common iliac artery, which in turn is derived from the abdominal aorta. In this research, we observed the same anatomical distribution of arteries (Fig.…”
