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.

子宫腺癌发生于 60%以上 4 岁及以上的雌性兔。为了治疗或预防这种子宫疾病，应进行卵巢子宫切除术。尽管需要了解卵巢、子宫和阴道的动脉供应情况，但很少有研究描述过动脉解剖结构。因此，我们在 15 只新西兰白兔和 15 只日本白兔中解剖了卵巢、子宫和阴道动脉，以阐明其解剖结构。卵巢动脉发自腹主动脉，在 50%的情况下，左侧动脉比右侧动脉更向前突出。卵巢动脉为卵巢、子宫和输卵管分支提供了三种分支类型。最常见的类型（右侧的一半中有 67%，左侧的一半中有 63%）显示出三个分支，它们分别独立于卵巢动脉。子宫动脉通常起源于脐动脉，其分支模式分为两种类型，分别有一条或两条子宫动脉。最常见的类型（右侧的所有一半和左侧的 83%）有一条源自脐动脉的子宫动脉。我们观察到三种阴道动脉起源类型，其中阴道动脉起源于髂内动脉的分支类型最为常见（右侧的一半中有 97%，左侧的一半中有 90%）。本研究确定的兔女性生殖器官的详细动脉供应模式将有助于进行兔妇科手术。解剖学记录，303：1478-1488，2020。©2019 美国解剖学会。
