The assessment of capillary vascular malformation (CM) morphology can be performed using videomicroscopy. Previously only the type of capillary pattern could be demonstrated. The Depth Measurement Videomicroscope (DMV) allows both depth and diameter of CM vessels to be measured. The aim of this study was to examine how videomicroscope recordings correlated with biopsy recordings and to investigate pressure-related changes in recordings when using the device. For the first part of the study, 10 patients with CMs resting in a temperature-controlled room were assessed with the DMV. Following this a 3mm punch biopsy of the area was taken. The depth and diameter measurements taken with the DMV were compared to those obtained histologically. For the second part of the study, pressure measurement was used to determine the amount of pressure required on the tip of the DMV to alter the results obtained. Five recordings were taken on the forearm of one volunteer. When the DMV and biopsy measurements are compared using a Bland and Altman Test to determine their relationship there is a close agreement with the diameter measurements and a correction factor of -0.100mm for the depth measurements. The pressure required to alter the skin microcirculation when placing the DMV on the skin surface was found to be 62mmHg. This corresponds closely with other studies of pressure effects on the skin microcirculation and exceeds the pressure used when using the DMV. The DMV thus provides a useful tool for assessing CM capillary structure.
可使用视频显微镜对毛细血管畸形（CM）的形态进行评估。以前只能显示毛细血管模式的类型。深度测量视频显微镜（DMV）能够测量CM血管的深度和直径。本研究的目的是检验视频显微镜记录与活检记录之间的相关性，并研究使用该设备时记录中与压力相关的变化。在研究的第一部分，对10名在温度受控房间休息的CM患者使用DMV进行评估。随后，对该区域进行3毫米的钻孔活检。将DMV测量的深度和直径与组织学获得的结果进行比较。在研究的第二部分，使用压力测量来确定DMV尖端所需的压力大小，以改变获得的结果。在一名志愿者的前臂上进行了五次记录。当使用布兰德-奥特曼检验比较DMV和活检测量结果以确定它们之间的关系时，直径测量结果有密切一致性，深度测量的校正因子为-0.100毫米。发现将DMV置于皮肤表面时改变皮肤微循环所需的压力为62mmHg。这与其他关于压力对皮肤微循环影响的研究结果密切相符，且超过了使用DMV时的压力。因此，DMV为评估CM毛细血管结构提供了一种有用的工具。
