OBJECTIVE
To analyze the anatomy of the perforating vessels irrigating the skin of the medial aspect of the thigh and originating from the secondary vascular pedicle of the gracilis muscle.
METHODS
We dissected 33 thighs from cadavers of both sexes to record and analyze the characteristics of the blood vessels irrigating the gracilis muscle in the middle third of the thigh.
RESULTS
All thighs (100%) had a secondary vascular pedicle in the intermuscular septum between the gracilis and vastus medialis/sartorius muscles, with branches irrigating the overlying skin on the medial aspect. The pedicle presented an arterial diameter ranging from 1.3 to 4.6 mm (mean: 2.3 mm) and a length ranging from 28 to 84 mm (mean: 50.6 mm). In 87.8% of the cases, the pedicle irrigated the gracilis muscle and presented vessels to the overlying skin.
CONCLUSION
Based on the data found, we conclude that it is feasible to obtain a reliable flap from the medial aspect of the middle third of the thigh.
目的
分析源自股薄肌二级血管蒂、灌注大腿内侧皮肤的穿支血管的解剖结构。
方法
我们解剖了33具男女尸体的大腿，以记录和分析灌注大腿中1/3段股薄肌的血管特征。
结果
所有大腿（100%）在股薄肌与股内侧肌/缝匠肌之间的肌间隔中有一个二级血管蒂，其分支灌注大腿内侧的覆盖皮肤。该血管蒂的动脉直径为1.3至4.6毫米（平均：2.3毫米），长度为28至84毫米（平均：50.6毫米）。在87.8%的病例中，该血管蒂灌注股薄肌并发出分支至覆盖皮肤。
结论
基于所发现的数据，我们得出结论，从大腿中1/3段内侧获取可靠皮瓣是可行的。
