Objective To make new approach of the interventional radiology in the treatment of LeggCalve-Perthes Disease. Methods 23 cases with Legg-Calve-Perthes Disease confirmed by X ray,CT,MRI clear diagnosis, and supper-selective catheterization of femoral artery was given in all children through medila and lateral circumfle femoral arteries and obtuator artery. The effects of thrombloytic,antispasmodic and vasodilator therapies were comfinned by digital subtraction angiography( DSA). Results The interventional radiology was administered to the patients once or twice. The pain disappeared and lameness obviously attenuated 3 months following the treatment. The imaging revealed estrusion of fossa capitis femoris, adsorption of dead bones, and formation of new bones. Conclusion the interventional radiology has the advantages of less trauma and complications, high concentration of drugs, and quick improvement of blood supply in local tissues, which makes possible the recovery of joint function and absorption of sequestrum during osteosis of children's development.%目的 探讨介入治疗儿童股骨头缺血性坏死的临床价值.方法 作者对23例经X线、CT、MRI诊断明确的早期股骨头缺血性坏死患儿,采用介入治疗技术,即经股动脉插管,选择性行旋髂内动脉、旋骼外动脉或闭孔动脉DSA血管造影,并灌注溶栓性药物、解痉药物及血管扩张药物.结果 23例儿童早期股骨头缺血坏死患儿经介入治疗1~2次,3个月复查,疼痛消失,跛行明显改善,影像学检查显示病侧股骨头塌陷变凸,死骨吸收,新骨形成.结论 儿童股骨头缺血坏死于骨质生长旺盛期,采取介入治疗方法,创伤小,并发症少,局部灌注药物浓度高,作用强,改善血供快,关节功能可望完全恢复.
