动脉变异与股骨头缺血坏死相关性研究

Artery variation is possible important factor of avascular necrosis of femoral head

目的提高对青壮年股骨头缺血坏死病因诊断及临床意义的认识。方法选择经临床和影像检查确诊并经介入治疗的78例113个缺血坏死股骨头的血管造影资料(观察组)与45例46个正常股骨头血管造影资料(对照组)对照分析。结果观察组股骨头供血动脉发育变异28例(35.9%),51支血管,其中髂内动脉壁支变异17支(33.3%),旋股内动脉变异29支(56.9%),旋股外侧动脉4支(7.8%),旋股内外动脉共干1支(2.0%)。对照组股骨头供血动脉发育异常5例5支,两组比较有显著性差异(P<0.05)。结论除外现病因,股骨头供血动脉发育变异是造成股骨头缺血坏死的重要因素,在诊断及治疗中应予重视。

Objective To make further understanding of the pathogeny diagnosis and clinical values about Avascular Necrosis of Femoral Head（ANFH） in young and prime of one＇s life. Methods Seventy-eight patients including 113 femoral heads in all with Avascular Necrosis of Femoral Head who were given interventional treatment proved by clinic or radiological examination were contrasted with 45 normal people including 46 normal femoral head and the angiography image were anallyzed. Results The artery variation of femoral head in interventional observation group was 28 cases, accounting for 35.9 %, 51 arteries, 17 internal iliac arteries variation （33.3%）, 29 medial femoral circumflex arteries variation （56.9%）, 4 lateral femoral circumflex arteries variation （7. 8% ）, 1 lateral and medial femoral circumflex arteries common bole variation（2.0% ） respectively. The artery variation of femoral head in control group was 5 cases, 5 arteries. There was remarkable by significant difference between the two groups （P 〈 0.05）. Conclusion Variations of the corresponding artery is one of important factors in ANFH patieuts.
