Bacterial Infective Stifle Arthritis Secondary to a Migrating Grass Seed Foreign Body in an Adult Dog

An adult neutered male cocker spaniel was presented with a 2-3week history of left pelvic limb lameness, stifle effusion, general malaise and pyrexia. Computed tomography (CT) imaging revealed an irregular tubular tract, extending from the stifle distally to the level of the mid tibial diaphysis, associated with the long digital extensor muscle. Ultrasonography revealed the tract had echogenic contents, however no foreign body could be identified. Following surgical exploration, a grass seed was identified in the medial compartment of the left stifle. Culture of the grass seed and joint capsule tissue yielded growth of Pantoea agglomerans. Following the surgery and subsequent antibacterial and non-steroidal anti-inflammatory medication, the dog made a full recovery to normal activity

Diagnostic and therapeutic approach of congenital solitary coronary artery fistulas in adults: Dutch case series and review of literature

Background Coronary artery fistulas (CAFs) are infrequent anomalies, coincidentally detected during coronary angiography (CAG). Aim To elucidate the currently used diagnostic imaging modalities and applied therapeutic approaches. Materials and Methods Five Dutch patients were found to have CAFs. A total of 170 reviewed subjects were subdivided into two comparable groups of 85 each, treated with either percutaneous 'therapeutic' embolisation (PTE group) or surgical ligation (SL group). Results In our series, the fistulas were visualised with several diagnostic imaging tests using echocardiography, multidetector computed tomography, and CAG. Four fistulas were unilateral and one was bilateral; five originated from the left and one originated from the right coronary artery. Among the reviewed subjects, high success rates were found in both treatment groups (SL: 97% and PTE: 93%). Associated congenital or acquired cardiovascular disorders were frequently present in the SL group (23%). Bilateral fistulas were present in 11% of the SL group versus 1% of the PTE group. The fistula was ligated surgically in one and abolished percutaneously in another. Medical treatment including metoprolol was conducted in two, and watchful waiting follow-up was performed in one. Conclusions Several diagnostic imaging techniques are available for assessment of the anatomical and functional characteristics of CAFs
