Department of Animal Pathology, Faculty of Veterinary Medicine, University of Torino, 10095 Grugliasco, Torino, Italy.Journal of Small Animal Practice (Impact Factor: 1.09). 03/2008; 49(2):100-2. DOI: 10.1111/j.1748-5827.2007.00426.x
A 12-year-old, male Yorkshire terrier was presented for acute pulmonary oedema. Thoracic radiographs showed a linear metallic foreign body within the cardiac silhouette. Echocardiogram showed a hyperechoic line extending through the left ventricle, the mitral valve, leading into the left atrium. A 4 cm long Kirschner wire was surgically removed by left fourth thoracotomy. The dog died two days after surgery for acute pulmonary oedema. Necropsy showed thrombi on the mitral leaflets that impeded their movement.

ABSTRACT: A dog that was referred to the University of Florida Veterinary Medical Center was discovered to have a bamboo skewer within the right atrium and right ventricle, traversing the tricuspid valve. The skewer was ingested approximately four months prior to referral and was partially removed via gastrotomy. The presenting complaint at the time of referral included coagulopathy, anemia and leukocytosis. A linear, hyperechoic structure was identified in the right heart during an echocardiogram. The foreign body was suspected to be a portion of the skewer that the patient had previously ingested. Cardiopulmonary bypass was performed and the foreign body was removed successfully. Complications following surgery included the development of tricuspid valve and ventricular wall thrombi, atrial flutter and amiodarone toxicity. Many indications have been described in the veterinary literature for cardiopulmonary bypass. However, to the best of the authors' knowledge, successful removal of an intracardiac foreign body with cardiopulmonary bypass has not been reported in a veterinary patient. This represents a new indication for cardiopulmonary bypass in veterinary medicine.

ABSTRACT: A 5-year-old male cat is presented for weakness and fatigue. Clinical examination revealed dyspnoea and pain on thoracic palpation. Radiography and echocardiography showed the presence of an intracardiac metallic foreign body (lead rifle pellet). The pellet was located in the interventricular septum at the level of the tricuspid valve. Definitive treatment was not possible but the cat is currently free of symptoms. To the author's knowledge, this is the first description of an intracardiac foreign body in a cat.

ABSTRACT: A 2 yr old female English setter dog was admitted for acute dyspnea. The dog underwent treatment of a T9T10 thoracic vertebral fracture subluxation at the authors' institution 15 mo earlier. Upon admission, a chest X-ray revealed a pneumothorax and a metallic foreign body in the left hemithorax. An emergency video-assisted thoracoscopic surgery was successfully performed to remove a 4.6-mm long Kirschner wire that migrated from the thoracic vertebral column to the thoracic cavity. The operating time was 27 min. The dog made an uneventful recovery and was discharged on the third day after surgery. Pneumothorax should be considered in patients that develop acute dyspnea and have a history of wire fixation in the thoracic vertebral column. Video-assisted thoracoscopic surgery is a safe and effective treatment of this condition.
