Generalized subcutaneous emphysema caused by concurrent cricoid cartilage fracture and cricotracheal detachment in a German shepherd dog

A dog was presented with history of progressive generalized subcutaneous emphysema and exercise intolerance secondary to dog fight. Radiographic evaluation confirmed extensive subcutaneous emphysema, pneumomediastinum and pneumoretroperitoneum. Surgical exploration revealed cricoid cartilage longitudinal fracture and cricotracheal detachment. The fractured cartilage was sutured and the cricoid cartilage and trachea was approximated using interrupted sutures. Concurrent cricoid cartilage fracture and cricotracheal detachment has not been reported in veterinary literature, which should be considered in any case of subcutaneous emphysema secondary to extrinsic laryngeal trauma

Experimental induction of left abomasal displacement: a new educational technique

The purpose of this study was to induce abomasal displacement to the left, and to let the undergraduate and post graduate students get used to the ping sounds of abomasum and other clinical manifestations. The procedure was carried out on eight young bulls, they were sedated and a 2 m flexible tube was inserted through the nasal canal into the rumen. By laparo-rumenotomy, 20 cm of the tube was inserted into the abomasums through the omaso-abomasal groove. The rumen wall and abdominal wall were apposed routinely. The animal was casted on its right side on the floor. The abomasum was inflated through the external end of the tube which was tied to bull's horn base. Then the animal was allowed to st and on its feet. The gas filled abomasum was mobilized to the left flank between the body wall and the rumen. The left abomasal displacement was confirmed by ping and ultrasonography. Experimental induction of left abomasal displacement by inflating the abomasum using a nasal abomasal tube following rumenotomy is a safe and suitable technique for educational and research purposes. Key words: Experimental induction, Left displaced abomasum, Bull

[Surgical repair of distal femoral fracture in a wild gray wolf [Canis lupus]]

A 3-year-old wild gray wolf was referred to the Department of Veterinary Clinical Sciences of Shiraz University with a history of car accident. The radiographic examination showed supracondylar distal femoral fracture in right leg. The wolf was pre-medicated by acepromazine followed by induction of anesthesia using a combination of diazepam and ketamine. Anesthesia was maintained by halothane. The fracture was reduced, the first pin was bent based on anatomical curvature of the femoral shaft and inserted from lateral epicondyle and drove proximally. The second one was inserted from medial epicondyle as a cross pin. For further stabilization, a bone plate was contoured to curve from the shaft onto the condyle and applied on lateral surface of the distal femur. The joint capsule and incision site was closed. Postoperative radiograph showed good pin placement and bone reduction. Cage rest and restricted activity was accomplished for 8 weeks. Postoperative follow up revealed no complication and the wolf was allowed to return to its domain area of wilderness four months after surgery. In conclusion, using a combination of different fixation techniques can result in successful fracture repair in wild animals
