Sirwas very interested in Mr. Pringle’s observations (Jan. 12), since he states that " amnion implantation has no demonstrable effect on the course of peripheral vascular disease ". This coincides with my observations in a limited series. My purpose, however, is to call attention to the possible value of this treatment in acrocyanosis. I referred1 to the use of this material in the following words: "
I have noted over the years that whereas the varix becomes in early pregnancy, the acrocyanotic limb may often improve. For this reason I implanted amnion in a series of limbs. Some of the patients were much improved. Results were too variable, however, for us to recommend this treatment. However, when stripping the limb which is the seat of both varicose and acrocyanotic trouble, the question of an amnion implant may be considered. It can do no harm, and on occasions the results are good. It should be remembered that incompetent varices cause more symptoms in a worse
