Abstract:
Objective To investigate the effect of retrograde sartorius myocutaneous flap for reparing skin defects of leg.Methods In the anatomic study,50 cadaveric lower limb were injected with red latex and the origin,diameter,course,distribution and anastomosis of sartorius's arteries were observed.Arteriographies were made in 4 sides of fresh specimens to study the arterial anastomosis in sartorius.Based on anatomic research results,we designed the retrograde sartorius myocutaneous flap for reparing skin defects of leg.Results Nutrient arteries of sartorius represented segnental distribution,Link-pattern arterial anastomosises were formed in sartorius by branches of adjacent vascular pedicles.Cutaneous arteries and musculocutaneous arteries above deep fascia formed interlocking arterial anastomosises net which provided blood supply for the skin on sartorius.The arterial branches in the distal 2/5 of sartorius came from saphenous artery,composed an arterial network around knee joint,which consist of anatomic basis for the blood supply of retrograde sartorius myocutaneous flap.Form February,2010 to April,2014,the retrograde sartorius myocutaneous flap were used to repair skin defects of leg in 2 cases.The flap size ranged from 7 cn×18 cm to 12 cm×25 cm.All flaps survived successfully with no ulcer.2 cases were followed up for 7 to 16 months.The skin color and texture were satisfactory.Conclusion the retrograde sartorius myocutaneous flap has constantly,reliable blood supply,and easily performed.It is an effective method for the reconstruction skin defects of leg.
