Percutaneous cementoplasty with lateral approach under regional anesthesia for acetabulum in patients with bone metastasis
Acta Orthopaedica Belgica(2018)
摘要
The purpose of this study is to demonstrate the surgical technique and to show the results of percutaneous cementoplasty (PC) for acetabular metastases using lateral approach under regional anesthesia. Forty-two cases underwent PC for acetabular metastases. The PC was performed using spinal anesthesia, lateral approach and fluoroscopic guidance. We assessed visual analogue scale (VAS) and revised musculoskeletal tumor society (MSTS) rating system and maximum standardized uptake value (SUVmax) of the acetabular lesion using F-18-FDG PET/CT before and after the PC. The mean injected volume of polymethylmethacrylamide to the pelvis was 21±11.8 ml. The mean of regional VAS (6.2±1.1 vs. 3.1±2.7, pu003c0.001), MSTS (10.3±3.9 vs. 18.3±3.2, pu003c0.001) and local SUVmax (8.6±5.2 vs. 5.7±3.6 , p=0.012) on PET/CT showed significant reductions after surgery. Twenty-three patients (55%) died of disease at mean 11.8±4.8 months after surgery. PC using lateral approach and regional anesthesia could be a simple and safe surgical method for relieving pain and maintaining skeletal stability against acetabular metastasis.
