Surgical treatment of hypervascular bone lesions can result in excessive operative blood loss. We reviewed the cases of eight patients who were operated on for hypervascular bone metastases from renal carcinoma after preoperative transcatheter embolization. The embolization was successful in six of these patients and their operative blood loss averaged only 550 milliliters (range, 450 to 750 milliliters). The reasons for failure in two patients were failure to recognize and embolize all major vessels supplying the tumor in the first and the presence of too many small vessels arising directly from the superficial femoral artery to embolize safely in the second. When surgical treatment of hypervascular bone metastases is indicated, consideration should be given to preoperative arterial embolization.
高血运性骨病变的手术治疗可能导致术中失血过多。我们回顾了8例因肾癌高血运性骨转移接受术前经导管栓塞术后进行手术的患者病例。其中6例患者栓塞成功，他们的术中平均失血量仅为550毫升（范围为450至750毫升）。2例患者失败的原因分别是：第一例未能识别并栓塞所有供应肿瘤的主要血管；第二例是由于直接发自股浅动脉的小血管过多，无法安全地进行栓塞。当需要对高血运性骨转移进行手术治疗时，应考虑术前动脉栓塞。
