The therapeutic effect of DCB was unexpectedly confirmed in the shrinking type.Clinical ImpactThe effectiveness of DCB in inhibiting smooth muscle cell proliferation in intimal hyperplasia lesions was expected based on the known mechanism of action of paclitaxel. However the therapeutic effect of DCB was unexpectedly confirmed in the shrinking type too. We may not need to hesitate usage of DCB for shrinking type.
