介入治疗股骨头缺血坏死21例近期疗效分析

Interventional Therapy for Avascular Necrosis of Femoral Head (A Therapeutic Analysis of 21 Cases)

目的 :探讨不同病因及影像分期的股骨头缺血性坏死的介入治疗效果 ,评价介入治疗对股骨头缺血性坏死的应用价值。材料和方法 :对 2 1例患者采用seldinger穿刺超选择插管至旋股内、外动脉 ,注入溶栓、血管扩张药物 ,治疗前后分别行DSA造影。结果 :2 1例患者在治疗后疼痛消失或不同程度缓解 ,血管造影显示治疗后股骨头血供改善。结论 :介入治疗是治疗股骨头缺血性坏死的有效方法 ,对早期病变和非外伤性因素 (激素、酗酒 )所致的股骨头缺血性坏死的疗效较好。

Purpose: To evaluate the interventional therapeutic effect of avascular necrosis of the femoral head with different canses and imaging degree and its clinical significance. Materials and Methods: 21 patients treated with the method of thrombolysis and vasodilation by Seldinger puncture throngh supercatheterizing and perfusing medial and lateral femoral circumflex arteries and underwent DSA imaging before and after treatment. Results: Pain were disappeared or released in all 21 patients after treatment. Angiography demonstrated increased in vessel count after treatment as compared with that before treatment. Conclusion: Interventional therapy is an effective method for treating avascular necrosis of the femoral head, the effect is better for those of earlier lesions and nontranmatic causes.
