[Embolism at the iliac bifurcation secondary to an atrial myxoma]

A 73-year-old woman presented a clinical picture of bilateral acute ischemia of the lower limbs. After embolectomy, transthoracic echocardiography revealed left atrial tumor. The picture was complicated by the onset of compartment syndrome in the lower extremities requiring decompressive fasciotomy. The excised atrial tumor proved to be a cardiac myxoma. Atrial myxoma, the most common benign cardiac tumor, leads to systemic, cardiac and embolic sequelae. Transthoracic echocardiography is the main diagnostic technique available, proving more useful than transesophageal echocardiography for small tumors. Such techniques can also be used during surgery, particularly in cases where preoperative assessment has left doubts about tumor location. We also argue in favor of early use of transesophageal echocardiography when peripheral arterial embolism is the diagnosis, in order to locate a cardiac focus as the cause of the clinical picture.
