摘要

爬行动物中很少有死前卵巢扭转和诊断病例的描述。本病例系列报告了2019年至2023年期间确诊为单侧卵巢扭转的5只成年(1-6岁)雌性壁虎(3只豹壁虎[Eublepharis macularius]、1只冠壁虎[Correlophus ciliatus]和1只石龙子壁虎[Rhacodactylus auriculatus])的临床和超声波检查结果。所有动物均表现为急性虚弱并伴有腹腔膨胀,其中一只动物患有慢性腹泻和恶病质。腹腔超声波检查(12兆赫线性探头)显示,所有病例均有双侧卵泡淤积和卵巢炎的迹象(异形卵泡直径≤1.3厘米),伴有卵巢周围大面积无回声边缘和高回声弦线,与卵巢血管扭曲一致。多普勒血流检测不到卵巢结构的血液供应,所有壁虎均被诊断为单侧卵巢扭转。在全身麻醉的情况下,对所有五只壁虎进行了双侧卵巢切除术。切除卵巢的重量在 7 到 15 克之间(占体重的 12.7-22.2%)。一只壁虎在术后1天死亡,其余四只在术后6个月健康。壁虎在爬行动物中是独一无二的,因为它们的排卵为单卵双生(在每个卵巢周期中,每个卵巢只排出一个卵泡)。所有五只壁虎都存在这种情况,并被怀疑导致卵巢扭转。本系列病例强调了超声波检查在爬行动物死前诊断生殖系统疾病方面的价值。

UNILATERAL OVARIAN TORSION IN FIVE GECKOS: CLINICAL AND ULTRASOUND FINDINGS.

Few cases of antemortem ovarian torsion and diagnosis have been described in reptiles. This case series reports clinical and ultrasound findings in five adult (aged 1-6 yr) female geckos (three leopard geckos [Eublepharis macularius], one crested gecko [Correlophus ciliatus], and one gargoyle gecko [Rhacodactylus auriculatus]) diagnosed with unilateral ovarian torsion between 2019 and 2023. All animals presented with acute weakness associated with coelomic distension, and one suffered from chronic diarrhea and cachexia. Coelomic ultrasound examination (12-MHz linear probe) revealed signs of bilateral follicular stasis and oophoritis in all cases (heterogenic follicles ≤1.3 cm diameter) associated with a large anechoic periovarian rim and a hyperechoic chord, consistent with twisted ovarian vessels. Blood supply to ovarian structures was not detected using a Doppler flow, and a unilateral ovarian torsion was diagnosed in all geckos. A bilateral ovariectomy was performed under general anesthesia in all five animals. The mass of the excised ovaries varied between 7 to 15 g (12.7-22.2% of body weight). One gecko died 1 d postsurgery; the four remaining animals were healthy 6 mon postsurgery. Gekkonids are unique among reptiles in that they undergo a monoautochronic ovulation (only one follicle is recruited by each ovary during each ovarian cycle); the presence of multiple vitellogenic follicles on each ovary facilitates the diagnosis of follicular stasis. This condition was present in all five geckos and was suspected to have led to ovarian torsion. This case series emphasizes the value of ultrasound examination for antemortem diagnosis of reproductive disorders in reptiles.

期刊介绍: The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
