[Interventional therapy in the treatment of avascular necrosis of femoral head and short-term efficacy].

OBJECTIVE

To evaluate the clinical effect of avascular necrosis of femoral head (ANFH) with interventional therapy in the near future.

METHODS

Twenty-eight patients (19 males, 9 females, the age was from 14 to 70 years old with an average of 38 years) with ANFH were treated by catheterization. The thrombolytic drugs, vasodilator drugs and improving microirculative drugs were respectively injected directly into the arteries supplying the femoral head after ultraselection. Contrasted the changing of the arteries suppplying the femoral head between pretreatment and posttreatment, and observed the bone density of the femoral head at 12-36 months after treatment,and analyzed clinical symptoms (hip pain and joint range of motion) improving.

RESULTS

The angiography showed the arteries supplying the femoral head were manifold, the coloration or the femoral head were enhanced after interventional therapy. The X-ray showed the bone density of the femoral head gradually recovered of nearly common by 97.2% (35/36). And hip pain and joint range of motion significantly improved than that of before treatment.

CONCLUSION

Interventiomal therapy is a safe and effective method to ANFH, which seems to be promising for wide clinical application.
