面部海绵状血管瘤的~(99m)Tc-RBC显像诊断与~(32)P胶体介入注射治疗

目的:探讨面部海绵状血管瘤的99mTc-RBC显像及32P胶体介入注射治疗的临床价值.方法: 海绵状血管瘤患者31例,依据瘤体表面面积分为A、B两组,行32P胶体介入多点位注射治疗,所有患者治疗前后均行99mTc-RBC血管瘤显像,先后采集动脉血流灌注相,早期血池相及延迟血池相图像.结果: 31例患者的动脉血流灌注相,早期血池相无放射性分布,而延迟相持续放射性浓聚.瘤内注射治疗后,一次治愈率为70.97%(22/31),其中A组治愈率为83.33%(15/18),B组治愈率为53.85%(7/13),经过第二次治疗,总治愈率为87.10%(27/31).治疗后再次显像,原放射性浓聚程度变淡,范围缩小或完全消失.结论: 99mTc-RBC显像对海绵状血管瘤的定性诊断与32P胶体介入注射治疗的疗效判定具有临床价值,32P胶体介入治疗疗效确切,方法简便,瘤体越小治疗效果越佳.

Diagnosis and interventional radiotherapy of cavernous hemangioma in face using ~(99m)Tc-RBC scintigraphy and colloidal ~(32)P

Objective:To evaluate the clinical value of 99mTc-RBC scintigraphy in the detection and follow-up of cavernous hemangiomas in face and the therapeutic effect of colloidal 32P interventional radiotherapy.Methods: Thirty one patients with congenital hemangioma in face were divided into 2 groups according to the area of hemangiomas.All patients were injected with certain dose of colloidal 32P and 99mTc-RBC radionuclide images were undertaken.The scanning procedure included an initial perfusion phase,followed b...
