经皮椎体成形术治疗椎体转移瘤的临床应用

目的 探讨经皮椎体成形术(PVP)治疗椎体转移性肿瘤的骨水泥灌注量、灌注方法及临床疗效.方法 对150例共218个椎体行椎体成形术,其中胸椎73个椎体,腰椎138个椎体,骶椎7个椎体,共218个椎体.手术在DSA监视下进行.根据椎体形态、破坏范围及穿刺点位置选择进针途径.结果 150例218个椎体手术全部成功,手术成功率100%,胸椎注入骨水泥2～5 ml,平均3.5 ml;腰椎注入3～8 ml,平均5.5 ml;骶椎4～7 ml,平均5.5 ml.术后疼痛完全缓解134例,89.3%;部分缓解15例,10%;无效1例,0.7%.150例中渗漏至椎间盘12例,硬膜外囊10例,椎旁静脉丛3例,椎旁软组织4例,骨水泥外漏发生率13.3%.术中及术后均无并发症发生.结论 经皮椎体成形术(PVP)对缓解或消除由椎体转移性肿瘤引起的疼痛有明显的治疗效果,值得临床应用推广.

The clinical application of percutaneous vertebroplasty on bone metastatic tumor

Objective To study the primary volume of bone cement and the method of perfusion and the clinical effect of percutaneous vertebroplasty for bone metastatic tumors. Methods Percutaneous vertebroplasty was performed in 218 vertebral bodies of total 150 patients,including 92 males and 58 females with age of 26-85,averaging 56.8 y. 218 vertebral bodies included 73 dorsal vertebra and 138 lumber vertebra and 7 sacral vertebra. Operations were taken under the DSA monitoring. The approach route was selected accord...
