色素レーザーによる血管腫の治療

Abstract

So far there has been many kinds of treatmant for hemangioma, bat none of them are satisfactory.In this experiments, the author used newly devised Dye Laser which be to intermittent pulse beams and could produce beams of different kinds of wave length.The author compared the Laser absorption of the hemangioma with that of the haemoglobin of the red blood cell and found both corelated considerably.From upper comparison, the author chose beams of 610 nm and 575nm nave length and applied them to the hemangiomatous lesion and compared their effects to the tissue. It became clear that the beam of 577nm wave length was absorped far more selectively to the Itemangiomatous tissue than that of 610nm and the tissue damages were found mostly in the hemangiomatous area, lieving the surrounding normal tissue mostly unchanged.As to the selective treatment of the lesion, there are the important factors, one is wave length and the other is the heat transmitting through the tissue.From these points of view, Dye Laser seems to be more prosperous as to the selective effect than other continuous wave beams.
