A case of epidural leakage after percutaneous vertebroplasty guided by fluoroscopic CT

概要

論文の詳細を見る
Percutaneous vertebroplasty is a procedure in which bone cement is injected into a fractured vertebral body in an attempt to stabilize fractured segments and alleviate pain. During this procedure, leakage of bone cement outside the vertebral body should be avoided. We experienced epidural leakage of bone cement upward from the injection level in a case guided by fluoroscopic CT to treat a Th6 spinal lesion caused by metastases. During the procedure, we did not notice bone cement leakage outside the vertebra within the region visible by CT. During percutaneous vertebroplasty guided by fluoroscopic CT, we must considered the possibility of bone cement leakage beyond the region visible by CT.
