Efficacy and safety of bone marrow aspiration and biopsy using fluoroscopic guidance and a drill-powered needle: clinical experience from 775 cases.

Objectives: To evaluate the efficacy and safety of performing a fluoroscopically guided bone marrow aspiration and biopsy (BMAB) using a drill-powered needle in a large patient population.

Methods: This retrospective study received institutional review board approval with a waiver of patient informed consent. We identified all BMAB procedures from August 2012 through December 2016 performed at our institution using fluoroscopic guidance and a drill-powered needle.

Percutaneous thermal ablation alone or in combination with cementoplasty for renal cell carcinoma osseous metastases: Pain palliation and local tumour control.

Introduction: To evaluate the safety and efficacy of minimally invasive percutaneous thermal ablation alone or in combination with cementoplasty for pain palliation and local tumour control of renal cell carcinoma osseous metastases.

Methods: Imaging-guided thermal ablation was performed in 59 renal cell carcinoma osseous metastatic tumours in 23 patients (concomitant cementoplasty in 43 tumours) selected following multidisciplinary consultations to achieve local tumour control and pain palliation (75%, 44/59) or pain palliation alone (25%, 15/59) in this retrospective study. Tumour characteristics, procedural details and complications were documented.
