title: [Pericardial perforation 2.5 years after kyphoplasty. A rare complication after cement extravasation].
abstract: Kyphoplasty is an established method in the treatment of osteoporotic spine fractures. In 10-15% of cases cement extravasation and leakage into veins occur. We report about the rare course of an extravasation. In 2008 an osteoporotic compression fracture of L(4) and L(5) in a 62-year-old female patient was treated by kyphoplasty. In the treated vertebra filling of an outgoing vein towards the proximal right side occurred. Postoperatively the patient was free of complaints (VAS preoperative 9/10, postoperative 1/10). In the chest X-ray a small asymptomatic filling of a lung vessel on the left side was present. The patient arrived as an emergency case 2.5 years later with decompensated heart failure. In the chest CT and angiography cement emboli in the lung were seen as well as a perforation of the pericardium with beginning tamponade. A thoracotomy was performed. Intraoperatively two 4 cm long sharp cement pieces were removed from the heart, which had perforated the right ventricle. Leakages were closed by suture. The patient survived the operation and was dismissed after 2 weeks of intensive care for rehabilitation and from there dismissed home. Six months later she had no more problems. When filling vertebra in several levels one must pay attention to introducing cement with a thick consistency, otherwise venous emboli and lung emboli may occur. These are as a rule asymptomatic, but may result in exceptional life-threatening complications.
