非创伤性股骨头坏死股骨头供血动脉解剖类型研究

目的:探讨非创伤性股骨头坏死患者股骨头供血动脉解剖类型及其对发病的影响.方法:回顾分析了60例75髋经旋股内外动脉插管造影融通术治疗的非创伤性股骨头坏死患者股骨头供血动脉造影资料,将其统计分析并与正常人进行对比,归纳出患者股骨头供血动脉解剖走行特点及旋股内、外动脉起源类型.结果:患者组股骨头血供深外干型(占41.10％)多于正常人组(占25％)；而深全干型(占34.25％)则少于正常人组(占52.78％).患者组旋股内侧动脉多起源于股动脉(占58.11％),正常人组多起源于股深动脉(占90.62％).而两组旋股外侧动脉同样多起自股深动脉.结论:非创伤性股骨头坏死患者股骨头供血动脉解剖类型与正常人之间存在一定差别,股骨头动脉的解剖类型异常可能对本病的发生产生一定的影响.

Femoral artery anatomy types of Non-traumatic osteonecrosis of the femoral head

Objective:To investigate the femoral artery anatomy types of non-traumatic osteonecrosis of the femoral head(ONFH) and their relationship with the incidence of the desease.Methods:From April 2010 to March 2011,60 cases(75 hips) of non-traumatic ONFH were treated by internal and lateral femoral circumflex artery cannula angiography.The angiogram data collected in the surgery were analyzed and compared with femoral artery anatomy types of normal human.The features of vascular distribution in patients and their types classified by origin were generalized.Results:In the included cases,the type of femoral artery mainly consisted of Lateral-trunk(account for 41.10%) whose proportion was higher than its counterparts in normal people(25%) and All-trunk(account for 34.25%) whose proportion was lower than normal people(52.78%).The medial circumflex femoral artery of patients most commonly originated from femoral artery(account for 58.11%) that was quite different from control group whose artery originated from deep femoral artery(90.62%) in most cases.The lateral femoral circumflex artery of both groups inclined to equally originate from deep femoral artery.Conclusion:There are distinct differences between normal people and non-traumatic ONFH in femoral artery anatomy types.The abnormal femoral artery anatomy types are deemed to have certain impacts on the incidence of non-traumatic osteonecrosis of the femoral head.
