Purpose

Fractures of the vertebral column are one of the most common complications of osteoporosis. Percutaneous vertebroplasty is a minimally invasive technique applying for the relief of pain and for the strengthening of bone in vertebral body lesions. Bone cement is injected into the fractured vertebra through a needle. Complication after injection such as pulmonary emboli may occur when the cement leaks into the veins. The authors aimed to describe the anatomy of the vertebral and paravertebral venous system and to establish its clinical implications, in order to better understand and anticipate complications that are related to the application of vertebroplasty.

Methods & Materials

20 patients from the Department of Neurosurgery were included in the study. All patients underwent contrast-enhanced MR venography (CE-MRV). Patients were imaged in the supine position. Imaging was performed without breath-hold. MR images were evaluated in consensus by three observers. All available MR images were scrutinized for the presence of venous structures.

Results

The lumbar venous system was subdivided into two main vascular systems â
