Nailfold capillary microscopy has been recently used among us, despite it has current use abroad for early diagnosis in connective tissue diseases. Its best value is to distinguish primary and secondary Raynaud's phenomenon and to predict connectivopathies, especially when added to antinuclear antibodies. The "SD pattern" consists in enlarged capllaries beside avascular areas, or focal desvascularization. In patients with suspected dermatomyositis, progressive systemic sclerosis or mixed connective tissue disease, SD pattern at nailfold capillaroscopy contributes to early diagnosis, with great benefit for the patient. It is, However, strongly indicated for this two groups of patients.
尽管甲襞毛细血管显微镜检查目前在国外用于结缔组织疾病的早期诊断，但我们最近也开始使用。它的最大价值在于区分原发性和继发性雷诺现象，并预测结缔组织病，特别是与抗核抗体检测相结合时。“SD模式”表现为无血管区旁的毛细血管扩张或局灶性血管减少。在疑似皮肌炎、进行性系统性硬化症或混合性结缔组织病的患者中，甲襞毛细血管镜检查的SD模式有助于早期诊断，对患者大有裨益。然而，强烈建议这两组患者进行此项检查。
