title: A Limb-Saving Procedure for Treatment of Arterial Cement Embolism during Lumbar Percutaneous Vertebroplasty: A Case Report.
abstract: As the major hazard of percutaneous vertebroplasty (PV), cement extravasation into the venous system, systemic embolism, and spinal canal has been previously reported. However, to our knowledge, only one case of the arterial migration of cement has been previously reported that is directly associated with this technique without any symptom in the immediate post-intervention and in the follow-up period. An arterial embolus of cement occurred in a 46-year-old woman undergoing lumbar PV for breast cancer metastasis. Less than one hour later, the patient complained of severe pain and numbness in her left leg. A diagnosis of acute left leg ischemia due to the acute occlusion of the infrapopliteal arteries by the cement was made. Transluminal angioplasty (PTA) for the infrapopliteal arteries was recommended because there were diffuse and long vessel involvements, leaving no distal targets for bypass vascular surgery. The patient's postoperative course was uncomplicated; the extremity tenderness and mottled skin were improved. A follow-up ultrasound 2 months later revealed an acceptable distal flow in the arteries of the affected limb, and the patient remained asymptomatic (except for a mild leg pain on exertion) at the one-year follow-up examination. In conclusion, PTA may save the limb from amputation in case of peripheral arterial embolism caused by cement during PV.
