Thoracoscopic splint placement reported for pectus excavatum in kittens: full analysis

A new feline surgery case series in the Journal of Small Animal Practice reports experience with video-assisted thoracoscopic placement of pectus excavatum splints in six kittens, describing successful correction of the sternal deformity with reduced intraoperative risk, according to the published abstract. The report focuses on kittens with pectus excavatum, a congenital concave deformity of the sternum that can reduce thoracic volume and, in clinically significant cases, impair respiratory and cardiac function.

That matters because external splinting is not new in veterinary medicine, but the way it’s usually performed has important limitations. In kittens with pliable sternebrae, external splinting has long been used to pull the sternum ventrally and maintain correction during growth. Prior literature, including a prospective cohort of 10 kittens, found excellent medium-term outcomes in six of seven severe cases treated with a ventral splint for four weeks. But standard circumsternal suture placement is often effectively blind, and clinical guidance for the technique explicitly warns about inadvertent puncture of the lungs or heart, pneumothorax, re-expansion pulmonary edema, infection, and recurrence.

The new case series appears to address that technical weak point directly. Based on the abstract, the authors used video-assisted thoracoscopic surgery, or VATS, to guide placement of external sternal splints in six kittens. The core value proposition is visualization: by seeing the intrathoracic structures during suture passage and splint positioning, surgeons may be able to lower the risk profile of a procedure that otherwise depends heavily on tactile guidance and experience. That fits with the broader trend in small animal surgery toward thoracoscopy for selected thoracic procedures, including pectus repair. (pmc.ncbi.nlm.nih.gov)

Recent feline case literature supports that trajectory, although it also underscores the challenges. A 2025 report of thoracoscopic-assisted stabilization with a locking compression plate in a Maine Coon kitten described VATS as a viable option for pectus excavatum repair, while noting the constraints imposed by the kitten’s very small thoracic cavity. A 2026 report describing cannula-assisted VATS correction in three cats concluded that routine VATS-assisted correction is possible, but said it may not always offer a clear advantage over traditional blind suture placement because visualization of the target sternebrae can still be difficult. In that context, a six-kitten series is useful because it expands the published clinical experience with minimally invasive guidance in this niche but high-consequence procedure.

Direct outside commentary on this specific paper was not readily available in public sources at the time of review, but existing expert guidance helps frame the likely clinical reaction. Karen Tobias and Whitney DeGroot, writing in Clinician’s Brief, describe external splinting as an option mainly for clinically affected kittens, especially younger patients whose sternums remain compliant, and recommend close follow-up with serial radiography and weekly rechecks while the brace is in place. Their review also highlights a practical reality for general practitioners and emergency teams: even when the concept is straightforward, execution and aftercare are demanding, and complications can be serious. That’s likely why refinements that improve intraoperative visualization are getting attention. (cliniciansbrief.com)

Why it matters: For veterinary professionals, the significance is twofold. First, the paper reinforces that pectus excavatum management in kittens is evolving from a purely open or blind technique toward more image-guided and minimally invasive approaches. Second, it may influence referral decision-making. If thoracoscopic guidance can make circumsternal suture placement safer, specialty centers may be better positioned to offer correction earlier in appropriate kittens, particularly those with respiratory compromise, exercise intolerance, poor growth, or imaging findings suggesting clinically meaningful thoracic restriction. At the same time, this is still a small case series, so it should be viewed as proof of feasibility rather than definitive evidence of superiority over conventional splinting. (cliniciansbrief.com)

What to watch: The next questions are whether the full paper reports any intraoperative complications, how long splints remained in place, what postoperative monitoring looked like, and whether follow-up showed durable correction without recurrence. Longer term, the field will be watching for larger comparative studies, clearer case-selection criteria, and whether VATS-guided splint placement becomes a repeatable standard at referral centers rather than an elegant but highly specialized technique.
