Cement venogram as a harbinger of methacrylate embolism after kyphoplasty: A case series

Vertebral compression fractures remain an important cause of pain and debility. Intractable pain may be approached with vertebral kyphoplasty. We herein present a case of symptomatic pulmonary cement embolism following kyphoplasty. Discovery of a paravertebral cement venogram at the time of this procedure prompted a case series review of our institutional experience with kyphoplasty. We found that cement embolization, whether symptomatic or discovered incidentally, was universally associated with a cement venogram at the site of vertebroplasty. We propose that a cement venogram be viewed as a harbinger of cement pulmonary embolism and this possibility be considered in patients with an existing intracardiac shunt or who present with new respiratory symptoms soon after kyphoplasty.
