背景:用于表现指动脉穿支(DAP)皮瓣的穿支动脉定位提出了挑战。这项研究旨在描述源自新鲜尸体三指指中适当指动脉的穿支动脉的解剖模式,并以此模式作为执行这些皮瓣的参考点。
方法:我们对28只新鲜的尸体手(14只男性,14个女性;10个右手,18左手)在向动脉系统注射乳胶后。解剖后的每个标本的数码照片和每个手指的穿支动脉的数量(第二至第五),指骨(近端,通过在AdobePhotoshopCS6中分析获得中端和远端)和手指侧(桡骨或尺骨)。
结果:当比较手指之间的穿支动脉数量的平均值时,我们获得了具有统计学意义的结果,方阵,手指侧,性别和偏侧性。当分析每个指骨中每个手指三分之一的穿支动脉数量时,我们发现,超过75%的标本在近端指骨的远端三分之二处和中指骨的三分之二处至少有一条穿支动脉,超过50%的标本在远端指骨的近端三分之一处至少有一条穿支动脉.
结论:我们提出了一种均匀的穿支动脉解剖模式,用手指,方阵,手指侧,性别和侧性,由远端近端指骨区域的高密度穿支动脉组成,在中间指骨和近端远端指骨区域,这将是最确定的区域,以帮助预测手指动脉穿支皮瓣的有利演变。
BACKGROUND: The localization of the perforator artery for the performance of digital artery perforator (DAP) flaps poses a challenge. This study aims to describe the anatomical pattern of the perforator arteries originating from the proper digital artery in fresh cadaveric triphalangeal digits and to use this pattern as a point of reference for performing these flaps.
METHODS: We performed a descriptive anatomical study on 28 fresh cadaveric hands (14 male, 14 female; 10 right hands, 18 left hands) after injecting the arterial system with latex. Digital photographs were taken of each specimen after dissection and the number of perforator arteries in each finger (second to fifth), phalanx (proximal, middle and distal) and finger side (radial or ulnar) were obtained by analysis in Adobe Photoshop CS6.
RESULTS: We obtained statistically significant results when comparing the means of the number of perforator arteries between fingers, phalanx, finger side, gender and laterality. When analyzing the number of perforator arteries in each phalanx third in each finger, we found that more than 75% of specimens had at least one perforator artery in the two distal thirds of the proximal phalanx and the three-thirds of the middle phalanx and more than 50% had at least one in the proximal third of the distal phalanx.
CONCLUSIONS: We present a homogeneous perforator artery anatomic pattern, by finger, phalanx, finger side, gender and laterality, consisting of a high density of perforator arteries in the distal proximal phalanx region, throughout the middle phalanx and in the proximal distal phalanx region, which would be the areas of greatest certainty to help predict the favorable evolution of a digital artery perforator flap in the fingers.
