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.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions and Clinical Relevance<\/jats:bold>\n                    \u2014Ovarian 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.\n                  <\/jats:p>","DOI":"10.2460\/javma.236.5.548","type":"journal-article","created":{"date-parts":[[2010,3,1]],"date-time":"2010-03-01T03:05:01Z","timestamp":1267412701000},"page":"548-553","source":"Crossref","is-referenced-by-count":85,"title":["Ovarian remnant syndrome in dogs and cats: 21 cases (2000\u20132007)"],"prefix":"10.2460","volume":"236","author":[{"given":"Rebecca L.","family":"Ball","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen J.","family":"Birchard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lauren R.","family":"May","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter R.","family":"Threlfall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gregory S.","family":"Young","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"J Am Anim Hosp Assoc","first-page":"290","article-title":"Ovarian remnant syndrome: revascularization of free-floating ovarian tissue in the feline abdominal cavity","volume":"37","author":"DeNardo","year":"2001"},{"key":"ref2","series-title":"J Vet Diagn Invest","first-page":"572","article-title":"Ovarian remnant syndrome in dogs and cats: 46 cases (1988\u20131992)","volume":"7","author":"Miller","year":"1995"},{"key":"ref3","series-title":"J Am Vet Med Assoc","first-page":"1065","article-title":"Theriogenology question of the month","volume":"219","author":"Root Kustritz","year":"2001"},{"key":"ref4","series-title":"Vet Clin North Am Small Anim Pract","first-page":"501","article-title":"The ovarian remnant syndrome in the bitch and queen","volume":"21","author":"Wallace","year":"1991"},{"key":"ref5","series-title":"Tijdschr Diergeneeskd","first-page":"1142","article-title":"Gynaecological complications following ovariohysterectomy in dogs, due to: (1) partial removal of the ovaries.
