Balloon-Expandable Aortic Stent-Graft for Treatment of Descending Aortic Rupture Presumably Secondary to Spiroserca lupi Larvae Migration

A 4 four-year-old, male, German shepherd dog was presented for acute weakness and respiratory difficulty. Radiographically, there was pleural effusion and subsequent pulmonary atelectasis. Hemothorax was diagnosed based on pleural fluid analysis. Using CT-angiography, a caudal thoracic focal aortic wall defect with surrounding mediastinal hematoma was detected. To prevent further aortic wall exsanguination a percutaneous covered stent was successfully deployed at the level of the aortic lesion under fluoroscopic guidance. The dog recovered uneventfully. This report illustrates the feasibility and therapeutic option of aortic rupture with percutaneous delivery of a covered stent in a dog.
