伤肢小隐静脉修复腘动脉损伤解剖基础与临床应用

The anatomy study on repairing injury of the popliteal artery with small sapheonus vein of the injuried limb and its clinical application

目的:为利用伤肢小隐静脉修复腘动脉损伤提供解剖学依据。方法:对25具标本50侧肢体的腘动脉和小隐静脉进行解剖研究并分别测量其管径。结果:腘动脉与小隐静脉解剖关系恒定,腘动脉管径起始段为(6.6±0.9)mm,中段为(5.9±1.0)mm,分叉前为(4.9±0.9)mm,小隐静脉管径汇入处为(3.1±0.1)mm,外踝平面和中段管径均为(2.9±0.1)mm,在小腿的上段小隐静脉与大隐静脉和深静脉间交通支出现率低。结论:腘动脉与小隐静脉解剖关系恒定,管径较相近,在伤肢小腿的上段切取一段小隐静脉对静脉回流无明显影响,临床应用21例22侧肢体,效果可靠满意。

Objective: To provide anatomical basis for the way of isolatin g small sapheonus vein to repair injuried popliteal artery. Methods: Small saphe onus veins and popliteal arteries on 50 sides of adult cadaveric lower extremiti es were observed and measured. Results: Small sapheonus vein and popliteal arter y had steady anatomic relationship. The average diameters of popliteal artery we re 6.6±0.9 mm at the original segment, 5.9 ±1.0 mm at the middle segment, 4.9 ±0.9 mm at the branch part. While the average diameters of small sapheonus vein were 3.1±0.1mm at the areas of the entrance, 2.9±0.1 mm at the middle segment and the external malleolus part. The appearance of rate was low in the communic ating branches of small sapheonus vein and popliteal artery. Conclusion: Both sm all sapheonus vein and popliteal artery system have a constant anatomical positi on and their diameters were similar. Removing a segment of small sapheonus vein to repair the injuried popliteal artery is possible.
