儿童股骨头缺血性坏死介入治疗探讨

目的 探讨介入治疗儿童股骨头缺血性坏死的价值。方法 4例患儿均采用股动脉插管超选择性行旋髂内动脉、旋骼外动脉或闭孔动脉DSA血管造影证实，并灌注溶栓性药物、解痉药物及血管扩张药物治疗。结果 儿童股骨头缺血性坏死介入治疗术，分别为2次及1次性，经治疗后3个月复查，疼痛消失，跛行明显改善，影像学检查发现病侧股骨头塌陷变凸，死骨吸收，新骨形成。结论 儿童患者骨质生长旺盛期，通过介入治疗。创伤小，并发症少，局部灌注药物，浓度高．作用性强，改善血供快，关节功能及死骨均可能完全恢复。

A novel approach to treat ischemic necrosis of caput femoris by interventional radiology in children

Objective To make new approach of the interventional radiology in the treatment of ischemic necrosis of caput femoris in children.Methods supper-selective catheterization of femoral artery was given to four children through medila and lateral circumflex femoral arteries and obtuator artery.The effects of thrombloytic,antispasmodic,and vasodilator therapies were comfirmed 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.
