Observations on aortic embolism; with report of thirteen additional cases.

Complete obstruction of the circulation to the lower extremities by lodgement of an embolus at the bifurcation of the aorta requires early surgical intervention if life is to be preserved and function retained.A summary of thirteen cases of aortic embolism is presented, including three apparently new etiologic factors. The literature is reviewed, and current cases compared with previously reported cases. A detailed report of aortic saddle embolus arising from auricular fibrillation in the absence of organic heart disease, and with complete return to health and heavy work, is reported.
