Summary
This case report details successful chest wall reconstruction in a dog with extraskeletal osteosarcoma using a 3D-printed titanium mesh implant. The innovative technique achieved excellent functional and cosmetic outcomes without recurrence or complications.
Area of Science:
- Veterinary Surgery
- Oncology
- Biomaterials
Background:
- A 6-year-old dog presented with a rapidly growing right chest wall mass, suspected to be malignant based on fine-needle aspiration.
- Computed tomography (CT) confirmed a large external and internal mass originating from the chest wall, causing breathing difficulties and pleural effusion.
Observation:
- The dog experienced respiratory distress due to pleural effusion, which was hemorrhagic but free of malignant cells upon analysis.
- Surgical intervention involved en bloc resection of the 7th-10th ribs and adjacent tissues, followed by reconstruction of the thoracic cavity.
Findings:
- A 3D-printed, contoured titanium mesh was utilized to reconstruct the extensive chest wall defect, secured to ribs and muscles.
- Histopathological diagnosis confirmed extraskeletal osteosarcoma. Postoperative CT at 8 months showed no recurrence, metastasis, or implant failure.
Implications:
- This is the first report of chest wall reconstruction using titanium mesh in a canine patient.
- Titanium mesh offers a viable solution for extensive thoracic defects, enabling successful reconstruction with minimal complications.

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.
