Abstract：
Osteosarcoma is the most common tumour that develops in the chest wall of dogs; an extensive excision is the treatment of choice. Various methods have been reported for reconstruction of chest wall defects following extensive excision. The objective of this report was to describe the complete resection of an extensive costal osteosarcoma with an extended resection of the ribs and part of the diaphragm in a dog. An 11-year-old neutered, male, miniature pinscher was presented with dyspnoea: An extensive mass was observed, stretching from the right chest wall to the abdominal wall. On computed tomography, the mass originated from the right 9th rib and exceeded the 6th rib on the cranial side and the 13th rib on the caudal side; it was compressing the lungs, diaphragm, liver, stomach and duodenum. When the patient\'s condition was medically stabilized, the tumour was removed from the right 9th rib. In consideration of the surgical margin, the 5th-13th ribs were excised, and the tumour was resected with the thoracoabdominal wall and part of the diaphragm. The missing thoracoabdominal wall and section of the diaphragm were reconstructed using two sheets of a polypropylene mesh. Postoperatively, flail chest was observed, although dyspnoea was not observed in the patient. Histopathological examination confirmed the diagnosis of osteosarcoma with a clean margin. Although 60.6 months have passed post-surgery, no metastasis has reoccurred. In this case, complete resection and reconstruction of the chest wall and diaphragm were achieved using a polypropylene mesh without fatal postoperative complications, despite extensive osteosarcoma resection.
摘要：
骨肉瘤是在狗的胸壁中发展的最常见的肿瘤;广泛切除是选择的治疗。已经报道了在广泛切除后重建胸壁缺损的各种方法。本报告的目的是描述对广泛的肋骨骨肉瘤的完全切除，并对狗的肋骨和隔膜的一部分进行了扩展切除。一名11岁的孩子绝育，男性,微型pinscher出现呼吸困难：观察到广泛的肿块，从右胸壁延伸到腹壁。在计算机断层扫描中，肿块起源于右第9根肋骨，超过了颅侧的第6根肋骨和尾侧的第13根肋骨；它正在压迫肺，隔膜,肝脏,胃和十二指肠。当病人的病情在医学上稳定时，肿瘤从右第9根肋骨切除.考虑到手术切缘,第5-13根肋骨被切除,切除肿瘤与胸腹壁和部分膈肌。使用两片聚丙烯网片重建缺失的胸腹壁和隔膜部分。术后,观察到连击胸部，尽管患者未观察到呼吸困难。组织病理学检查证实了骨肉瘤的诊断，边缘清洁。尽管手术后已经过去了60.6个月，没有复发转移。在这种情况下,使用聚丙烯网片完成胸壁和隔膜的完整切除和重建，没有致命的术后并发症，尽管进行了广泛的骨肉瘤切除。
