To describe signalment, clinical findings, diagnostic tests, and results of treatment of dogs and cats with ovarian remnant syndrome (ORS).
Retrospective case series.
19 dogs and 2 cats with ORS.
Medical records for animals examined between June 2000 and October 2007 were reviewed for signalment, clinical signs, age at time of ovariohysterectomy (OHE), surgical findings during OHE, experience of the surgeon (veterinary student vs veterinarian), interval from OHE until diagnosis of ORS, results of diagnostic tests, surgical findings, and results of histologic examination of excised tissues.
21 animals (19 dogs and 2 cats) with ORS were identified. The most common clinical signs were those associated with proestrus and estrus. More dogs than cats were affected, and all residual ovarian tissues were found in the region of the ovarian pedicles. The right ovary in dogs was affected significantly more often than the left ovary. Seven animals had neoplasms of the reproductive system. These animals had a significantly longer interval between OHE and diagnosis of ORS than did the 14 animals without neoplasms. Long-term follow-up of 18 animals revealed resolution of clinical signs following exploratory laparotomy.
Ovarian remnants were found in typical locations for ovaries and were not considered ectopic tissue; thus, surgical error during OHE was suspected as the cause of ORS. Anatomic differences may account for differences between species, and clinical signs may not be recognized until years after OHE. Surgical removal of residual ovarian tissue resulted in resolution of clinical signs.
描述患有卵巢残留综合征（ORS）的犬猫的特征、临床症状、诊断测试及治疗结果。
回顾性病例系列研究。
19只犬和2只猫患有ORS。
回顾2000年6月至2007年10月期间接受检查动物的病历，记录其特征、临床症状、卵巢子宫切除术（OHE）时的年龄、OHE期间的手术发现、外科医生的经验（兽医专业学生与兽医）、从OHE到诊断ORS的间隔时间、诊断测试结果、手术发现以及切除组织的组织学检查结果。
共识别出21只患有ORS的动物（19只犬和2只猫）。最常见的临床症状与发情前期和发情期相关。受影响的犬比猫更多，所有残留的卵巢组织均在卵巢蒂区域发现。犬的右侧卵巢受影响的频率明显高于左侧卵巢。7只动物患有生殖系统肿瘤。与14只无肿瘤的动物相比，这些动物从OHE到诊断ORS的间隔时间明显更长。对18只动物的长期随访显示，剖腹探查术后临床症状消失。
卵巢残留位于卵巢的典型位置，不被视为异位组织；因此，怀疑OHE期间的手术失误是ORS的病因。解剖学差异可能解释了物种间的差异，临床症状可能在OHE后数年才被识别。手术切除残留的卵巢组织可使临床症状消失。
