目的 探讨恶性骨肿瘤的血管造影（DSA）表现，寻找经动脉灌注与高强度聚焦超声（HIFU）联合治疗后评价疗效的影像学指标。方法 观察了27例恶性骨肿瘤患者DSA表现， 比较其治疗前后血管造影变化情况。结果 联合治疗后血管造影可见肿瘤血湖的改变最明显，好转率为82.6%，其次是肿瘤染色的减少或消失为77.3%，同时其它各种恶性骨肿瘤的DSA征象均有不同程度好转。结论 血管造影可作为恶性骨肿瘤动脉灌注与HIFU联合治疗后检测疗效和判断预后的可靠指标。
Objective To investigate the angiographic features of malignant bone tumors (DSA) and to find the imaging parameters for the evaluation of therapeutic effect after arterial perfusion and high intensity focused ultrasound (HIFU). Methods The DSA findings of 27 patients with malignant bone tumors were observed. The changes of angiography before and after treatment were compared. Results The results of angiography showed that the change of blood lakes was the most obvious. The rate of improvement was 82.6%, followed by the decrease or disappearance of tumor staining of 77.3%. Meanwhile, the signs of DSA in other malignant bone tumors all improved to some extent. Conclusion Angiography can be used as a reliable indicator of curative effect and prognosis after arterial perfusion of malignant bone tumor combined with HIFU.
