摘要
目的 探讨肘部动脉吻合网对于上肢轴型皮瓣扩大切取的意义。方法 选取 2 7侧新鲜成人尸体上肢制成 ABS铸型标本 ,逐层腐蚀、即时观察肘后、肘外侧区动脉吻合网的血供来源、分布 ,观测吻合血管的数量和总截面积 ,并与肘前区及肘内侧区进行比较。结果 肘后区的吻合支数量达 (8.6 4± 2 .74)支 ,截面积(0 .48± 0 .11) m m2。肘外侧区吻合支为 (8.30± 1.19)支 ,截面积 (0 .37± 0 .0 3) mm2。具有丰富的动脉吻合网。结论 肘后。
Objective To explore the importance of the posterior and lateral arterial network of elbow in the application of the super regional and mutual pedicled axial flap.Methods Twenty seven upper extremities of adult cadavers were prepared as casts of Acrylomintril Batradiene Styrene(ABS) resin and corroded in a strong solution of NaOH according to natural layers of human tissue.The source,site and structure of the posterior and lateral arterial network of elbow were observed,the number and total sectional area of anastomosing branches crossing the line between two humeral epicondyles were measured and compared with the medial and anterior region. Results There are 8.64±2.74(36.42%) and 8.30±1.19(35.0%) anastomosing branches crossing the posterior and lateral regions, and total section areas are (0.48±0.11)mm 2 and (0.37±0.03)mm 2 respectively.So there is very rich arterial network arround the elbow. Conclusion The enough number of anastomosing branches and their section areas of the posterior and lateral region of the elbow make it possible to connect super regional and mutual pedicled axial flaps crossing the elbow.
