Parasternal thoracotomy via sternocostal disarticulation can be performed in cats with good short-term outcomes.

Abstract

OBJECTIVE: To describe the short-term outcomes and complications in cats following parasternal thoracotomy via sternocostal disarticulation. METHODS: Medical records of cats that underwent parasternal thoracotomy at a single private practice from October 2017 to October 2023 were reviewed. Signalment, diagnoses, surgical details, hospitalization time, complications, and short-term outcomes were recorded. Follow-up thoracic radiographs were retrospectively reviewed, when available, for any closure-related abnormalities. RESULTS: Of 25 cats that underwent parasternal thoracotomy for treatment of various diseases, 92% survived to discharge. All cats surviving to discharge also survived at least 10 days postoperatively. Postoperative complications were noted in 50% of cats. Seven of the 12 complications (58%) were incidental sternal or sternocostal abnormalities noted on radiographs. Two cats (8.7%) experienced incisional complications, both of which were minor. CONCLUSIONS: Cats undergoing parasternal thoracotomy via rib disarticulation had a favorable short-term survival rate. The identified radiographic abnormalities were not suspected to be clinically significant, and no other complications unique to this approach were identified. CLINICAL RELEVANCE: Parasternal thoracotomy may be a suitable alternative to traditional approaches when thoracic exploration is indicated in cats.
