Treatment of canine nasopharyngeal stenosis using balloon‐expandable metallic stents: long‐term follow‐up of four cases

Four dogs were diagnosed with nasopharyngeal stenosis using endoscopy and magnetic resonance imaging. Treatment using balloon-expandable metallic stent, placed under fluoroscopic and endoscopic guidance, resulted in immediate resolution of clinical signs. All dogs were clinically normal 40 to 62 months following stent placement.
