Use of a balloon occlusion catheter to facilitate transarterial coil embolisation of a patent ductus arteriosus in two dogs

Two dogs with a history of coughing and exercise intolerance were suspected to have a patent ductus arteriosus (PDA), and the presence of a type III PDA was confirmed by radiography, electrocardiography, ultrasonography and angiography. Transarterial coil embolisation was carried out by using a modified technique. An occlusion balloon catheter was inserted through a femoral vein and placed at the pulmonary side of the ductus before the embolisation culls were put in place. Both dogs remained healthy during a follow-up period of nine months

Magnetic resonance arthrography of the cubital joint in dogs affected with fragmented medial coronoid processes

Objective-To evaluate efficacy of intra-articular injection of gadolinium tetra- azacyclododecane tetraacetic acid (gadolinium-DOTA) for delineating fragmented medial coronoid processes (FMCP) and lesions on the medial aspect of the humeral condyle (MAHC). Sample Population-14 cubital joints in 9 dogs. Procedure-Magnetic resonance imaging (MRI) was performed with and without intra-articular injection of a solution of 2 mmol of gadolinium-DOTA/L. Arthrographic images obtained after injection of contrast medium were compared with those obtained without contrast medium. Evidence of contrast medium around or in the medial coronoid process and infiltration of contrast medium in subchondral bone lesions was recorded, Twenty-four hours after imaging, arthroscopy was performed, and lesions detected were correlated with results of MRI. Results-An abnormal coronoid process was diagnosed in 13 of 14 joints. A fragmented process (free) was seen in 7 of 14 joints; nondisplaced mineralized medial tin situ) coronoid processes were evident in 4 joints; and nondisplaced unmineralized medial coronoid processes were evident in 2 joints. Lesions on the MAHC were diagnosed in 4 of 12 joints. In 5 joints, a hyperintense signal resulted from contrast medium that infiltrated between the fragmented process and ulna. In 2 joints, contrast medium did not infiltrate completely around the process and was stopped by an isointense structure tie, abnormal cartilage). Subchondral bone lesions were enhanced by use of contrast medium. Conclusion and Clinical Relevance-Use of arthrography enabled us to identify FMCP easily, but did not provide important additional information about changes on the medial coronoid process, compared with MRI performed without contrast medium

Hemiurothorax following diaphragmatic hernia and kidney prolapse in a cat.

A 3-year-old cat was presented with increasing dyspnoea over the past four days. Unilateral pleural effusion was diagnosed and a modified transudate was drained several times. Surgical exploration revealed intra-thoracic prolapse of the left kidney and partial herniation of the spleen through a dorsal, circumferential diaphragmatic tear. Biochemical analysis of the pleural fluid confirmed urothorax. Due to excessive fibrin deposit on the well-vascularised kidney it was impossible to re-establish left urinary pathways. Left-sided nephrectomy and diaphragmatic herniorrhaphy were performed. Postoperative recovery was uneventful and complete. This is the first report of an urothorax in veterinary medical literature.
