Vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body / 中国骨伤

OBJECTIVE@#To evaluate the early clinical efficacy and safety of vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body.@*METHODS@#The clinical data of 19 patients(21 segments) with spinal metastases complicated by posterior wall destruction of vertebral body treated from January 2016 to January 2017 were retrospectively analyzed. There were 15 males and 4 females, aged 40 to 85 years old with a mean of (66.00±10.25) years . All patients had severe low back pain before the operation, which were diagnosed by CT as damage-type metastatic tumor of the vertebral posterior wall. All patients were treated by vesselplasty technique. Nineteen vertebrae received percutaneous unilateral pedicle puncture and two vertebrae received percutaneous bilateral pedicle puncture. VAS, ODI were recorded before operation, 1 d and 3 d after operation respectively. X-ray and CT scan were used to observe bone cement leakage and complications.@*RESULTS@#All the operations were successful and postoperative pain was significantly relieved. Postoperative VAS score and ODI of the two groups were significantly improved (<0.05). A small amount of bone cement leakage occurred in one vertebral body, which was a vertebral venous plexus leakage, but no clinical symptoms after operation.@*CONCLUSION@#Vesselplasty for the treatment of spinal metastases complicated by posterior wall destruction of vertebral body can significantly reduce the symptoms of thoracolumbar back pain, improve the quality of life, reduce the incidence of bone cement leakage, and has high clinical efficacy and safety.

Percutaneous vertebral augmentation with the Vessel-X bone void filling container system: A preliminary clinical trial / 中国微创外科杂志

Objective To explore the clinical effectiveness and safety of percutaneous vertebral augmentation with the Vessel-X bone void filling container system (Vesselplasty). Methods Three cases of fresh osteoporotic vertebral compression fracture were treated with Vesselplasty. After procedure, the pain relief, the fracture reduction, and the cement distribution in the vertebra were observed. Results All the 3 cases were treated with the unipediclar injection technique. The operative time was 45, 32 and 30 min, respectively. The hemorrhage volume was
