Capillaroscopy produces in vivo images of skin microcirculation. It is a simple, noninvasive tool for analyzing microvascular abnormalities and, as such, can be used in both adults and children. Capillaroscopy has proven useful in many diseases, but it is of particular value in Raynaud phenomenon and other autoimmune diseases. The test is used to analyze capillaroscopic patterns in the nailfold bed of the second to fifth fingers of each hand. A normal capillaroscopic pattern is characterized by the presence of 7 to 11 capillaries in a hairpin shape. Pathologic patterns are characterized by morphologic and structural alterations, such as ectasias, giant capillaries, pathologic hemorrhages, avascular areas, and neoangiogenesis. In this article, we review the fundamentals of capillaroscopy, with an emphasis on the technique and its indications, diagnostic value, and use as a prognostic tool for rheumatologic disorders.
毛细血管镜检查可生成皮肤微循环的体内图像。它是一种用于分析微血管异常的简单、无创工具，因此可用于成人和儿童。毛细血管镜检查已被证明在许多疾病中有用，但在雷诺现象和其他自身免疫性疾病中具有特殊价值。该检查用于分析每只手第二至五指甲襞床的毛细血管镜图像。正常的毛细血管镜图像特征是存在7至11条发夹状毛细血管。病理图像的特征是形态和结构改变，如扩张、巨大毛细血管、病理性出血、无血管区和新生血管形成。在本文中，我们回顾毛细血管镜检查的基本原理，重点是技术及其适应证、诊断价值以及作为风湿病预后工具的应用。
