Crimped monofilament nylon leader for median sternotomy closure in 10 dogs.

Abstract

To describe and report the outcomes after closure of median sternotomies with crimped monofilament nylon leader (MNL) in dogs. Retrospective observational study. Dogs (n = 10) that underwent intrathoracic surgery through a median sternotomy approach. The median sternotomy was closed in a peristernal figure eight pattern with crimped MNL. Medical records were reviewed for clinical and histopathological findings and complications. Owners or veterinarians were contacted to collect long-term follow-up information. The technique was simple, with no intraoperative complications. Postoperative infection was documented in one dog, requiring removal of a single MNL and associated crimp clamp. Delayed healing of the surgical incision in one dog was managed conservatively. No other complications were documented throughout long-term follow-up at a median of 488 days (range, 199-608). Median sternotomies were successfully closed with crimped MNL and were associated with a low complication rate. Crimped MNL represents an alternative method to close median sternotomies in dogs.
