Aortic thromboembolism. A different predisposing disease in four dogs: a case report

摘要

Four dogs had signs of pelvic limb lameness, pain, and collapse resulting from an occlusion of the distalaorta or the iliac arteries by thrombi. The diagnosis of an aortic thromboembolism was based on the absence orweakness of a femoral pulse, and the two-dimensional and Doppler ultrasonography of the abdominal aorta, iliac,and femoral arteries. Three dogs had a concurrent disease predisposing to thrombosis, including hyperadrenocorticism,protein losing nephropathy, neoplasia, and cardiac disease. Three dogs were treated with a tissue plasminogenactivator (t-PA) in an attempt to lyse the thrombosis; two regained pelvic limb function. The other two dogsdied shortly after the diagnosis of a thrombosis. A complete description of the history, clinical signs, laboratoryanalysis and imaging studies is included. Moreover, a review of the aortic thromboembolism, a diagnosis protocoland the options for its treatment are discussed.
