The authors present their experience with Morphologic Capillaroscopy, and analyze the diagnostic dates provided by this technique to the current Angiology and Vascular Surgery protocols. Morphologic anomalies founded during diverse systemic diseases as well as the changes on the capillary field produced in cases of chronic ischaemia and venous insufficiency were analysed. The study was made on the basis of 236 capillaroscopic images and it was completed by an extensive bibliographic review of the subject.
