Abstract:
Objective To study the curative effect of ischemic necrosis of femoral head by interventional thrombolysis.Methods By applying Seldinger's technique,the catheter was guided via arteria femoralis with super-selection into circumflexa femoris medialis,lataralis,and acetabuli to performed the interventional thrombolysis in 50 cases(60sides)with necrosis of femoral head.Results All patients were followed-up for 6~48 months,combined with angiography,the clinical symptoms and the change of bone.The curative effect was evaluated.The ratio of excellent and better effect was 91.4%,the ratio of the improvement of angiography was 87%.the angiography showed that after treatment,the supply artery of femoral head was increased in number;the stained area of femoral head was extended,the capillaries were incereased and the reflux of vein was remarkably improved.The ratio of the improvement of clinical symptom was 96.6%.90% of the necrotic area of femoral head showed hyperplasia,sclerosis,and reduction of cystic changes.Conclusion The interventional therapy by leading to target vascular with thrombolysis in treating necrosis of femoral head has remarkable therapeutic effect.
