穿支血管远端分支模式与股前外侧薄皮瓣失败有关。本研究的目的是探讨使用光声断层扫描作为诊断成像模式，以确定前外侧大腿穿支及其分支模式在皮下层的可行性。研究了5名健康男性的10条大腿。使用光声断层扫描检查大腿中部的前外侧。评价了光声断层成像与超声检查结果之间的相关性。为了确定深度光声断层扫描的可检测性，将股骨柄部分中的血管深度与超声测量的深筋膜深度进行比较。通过三维观察评价脂肪层和筋膜上层血管的分支模式。光声断层扫描共观察到18条交通支。光声断层扫描和超声在检测穿支血管方面具有可比的诊断潜力。光声断层成像可视化微血管在皮下层，特别是那些在倾斜或水平方向。可视化血管的估计平均深度为9 mm，最大深度为13 mm。干部可视化血管的深度与深筋膜的深度之间有很强的相关性。光声断层图像的三维观察显示了穿支的分支形态。这项研究表明，光声断层扫描的适用性，以确定在体内的大腿前外侧穿支的分支模式，虽然有限的可视化筋膜下血管是一个技术问题。作者认为，光声断层扫描有可能成为一种新的成像模式薄股前外侧皮瓣手术。
The distal branching pattern of perforators is associated with thin anterolateral thigh flap failure. The purpose of this study was to investigate the feasibility of using photoacoustic tomography as a diagnostic imaging modality to identify anterolateral thigh perforators and their branching patterns in the subcutaneous layer. Ten thighs in five healthy men were studied. The anterolateral aspect of the midthigh was examined using photoacoustic tomography. The correlation between photoacoustic tomography and ultrasound findings was evaluated. To determine the detectability of photoacoustic tomography by depth, the depth of vessels in the stem portion was compared to the depth of the deep fascia measured by ultrasound. Branching patterns of vessels in the adipose and suprafascial layers were evaluated by three-dimensional observation. A total of 18 perforators were visualized by photoacoustic tomography. Photoacoustic tomography and ultrasound had comparable diagnostic potential for the detection of perforators. Photoacoustic tomography visualized microvessels in the subcutaneous layer, especially those in oblique or horizontal orientations. The estimated mean depth of visualized vessels was 9 mm; the maximum depth was 13 mm. There was a strong correlation between the depth of visualized vessels in the stem portion and the depth of the deep fascia. Three-dimensional observation of photoacoustic tomographic images showed the branching morphology of perforators. This study showed the applicability of photoacoustic tomography to identification of the branching patterns of anterolateral thigh perforators in vivo, although limited visualization of subfascial vessels is a technical issue. The authors believe that photoacoustic tomography has the potential to be a new imaging modality for thin anterolateral thigh flap surgery.
