Methods Vasodilator, thrombolytics and promoting microcirculatory drug were directly injected into the feeding arteries of the avascular necrotic femoral heads, under the condition of applying the blood stoppage belt at the root of thigh with pressure before the drug injection into the femoral pronator and extension arteries. The treatment was repeated 45 d later. Urokinase 10 5 unite/d ?10 were administrated with venous infusion ipsilaterally on the 15th day after the beginning of the therapy. Imaging features and clinical symptoms were recorded and correlatively studied before and after the treament. Results Symptoms relief especially the pain reached 100% after the treatment with various degrees of bony repair and new bone formation. Furthermore, increase caliber of feeding small arteries for femoral head and multiplicity of microvasculature, shortening of opacification time were revealed by DSA. IV stage bony change showed mild or inconspicuous. Conclusions Interventional catheterization treatment for avascular femoral head necrosis, especially the patients of fore Ⅲ stage, is safe and effective.
