Vascular interventional treatment of avascular necrosis in 28 cases

Objective To evaluate the therapeutic effect of intra-arterial thrombolysis in treatment of avascular necrosis.Methods 28 patients with 33 avascular necrosis received interventional therapy.Seldinger technique was used to enter contralateral femoral artery,and the 5F Cobra was sent super-selectively to femoral internal and external arteries.Papaverine,low molecular heparin,compound Danshen and urokinase were injected.Re-angiography was done after thrombolysis to observe the blood supply of the femoral head.Results In 28 patients with a total of 33 lateral femoral head avascular necrosis,the pain relief rate was 100% after interventional therapy;the pain disappeared in 70%(23/33);Hip joint can be comfortable with walking in 54.5%(18/33),while angiography showed that the femoral head blood supply thickening of small arteries,increasing blood supply improved significantly.Conclusion Vascular Interventional treatment of ischemic necrosis of femoral head is a simple operation,less trauma and clinical symptoms improved,it is worth promoting.
