Capillary blockage is a relatively common type of clinically occluded vascular disease. Since the local peripheral capillaries are relatively thin, once the capillaries are blocked, there is no way to treat them clinically by surgery. If the capillary blockage is limited and the symptoms are not very obvious, the main treatment means is oral medication and conservative treatment. The drugs are mainly oral drugs to dilate blood vessels and improve peripheral circulation, which can promote the generation of new capillaries. Therefore, clinically, there is no way to unblock the capillaries, but only through drugs or other exercise therapy to promote the generation of new capillaries and improve the symptoms of ischemia caused by the original local capillary blockage. One of the reasons why capillary blockage cannot be unblocked is that conservative drug treatment cannot unblock the blood vessels. Secondly, surgical treatment that can unblock blood vessels cannot be performed on capillaries, because capillaries are too small. Therefore, once capillary blockage occurs clinically, it is necessary to take regular oral medication for a long time and review regularly to avoid further progress causing blockage of the main vessels.
