For the treatment of lytic disease involving the pedicles of vertebrae in patients with metastatic disease, the authors performed percutaneous vertebroplasty by using an access route via the lysed pedicle. Fifty-one pedicles were treated in 32 consecutive patients. In all cases, a radiologically satisfactory filling of both the affected pedicle and the(More)
Minimally invasive techniques for the treatment of some spinal diseases are percutaneous treatments, proposed before classic surgery. By using imaging guidance, one can significantly increase accuracy and decrease complication rates. This review report physiopathology and discusses indications, methods, complications and results of performing these(More)
We carried out MRI on 16 male and three female comatose patients, aged 2 days to 79 years, with suspected cortical ischaemia referred from our intensive care units. Using a head coil, and following standard imaging, including coronal fluid-attenuated inversion-recovery images, we performed diffusion-weighted imaging (DWI) using a whole-brain multislice(More)
PURPOSE To describe a new fluoroscopically guided technique for osteoplasty (or cementoplasty) of the superior and inferior pubic rami and ischial tuberosities and to provide information about the access routes and initial results on pain management after this technique. MATERIALS AND METHODS Twenty-three lytic metastases of the superior and inferior(More)
We wished to measure the absorbed radiation dose during fluoroscopically controlled vertebroplasty and to assess the possibility of deterministic radiation effects to the operator. The dose was measured in 11 consecutive procedures using thermoluminescent ring dosimeters on the hand of the operator and electronic dosimeters inside and outside of the(More)
Percutaneous vertebroplasty was performed via a transoral route in a 70-year-old woman with a C2 metastasis of thyroid origin involving anterior vertebral elements. Complete pain relief was obtained after an uncomplicated minimally invasive procedure. This preliminary experience demonstrates that a transoral approach under fluoroscopic control can provide(More)
STUDY DESIGN During vertebroplasty (VP), polymethylmethacrylate (PMMA) may leak into the posterior epidural venus plexus, provoking symptoms ranging from radicular pain to medullar compression. OBJECTIVES To propose and test the feasibility of a procedure (cooling system) to prevent radicular irritation caused by foraminal PMMA leakage. SUMMARY OF(More)
OBJECTIVES To evaluate the short-term analgesic effect of sacroplasty in patients with osteoporotic sacral fractures. METHODS Single-center retrospective observational study of all patients managed with sacroplasty for osteoporotic sacral fractures between October 2008 and November 2009. For each patient, symptom duration, pain intensity, and analgesic(More)
Diffusion-weighted MR imaging (DWI) is particularly sensitive for the detection of acute stoke. Until recently, DWI was performed with EPI technology. We compared 18 patients with clinical suspicion of acute stroke on a standard 1.5T unit and an open low-field MR scanner. Eighteen patients with 20 lesions of acute stroke were studied retrospectively with(More)
