At the New York Post-Graduate Medical School and Hospital in Dr. H. D. Furniss' service we had up to May, 1927, insufflated the fallopian tubes of considerably more than 200 women without any fatality or even untoward results of any nature. Nevertheless, accidents with the insufflation test of the fallopian tubes are now and again reported in the literature,1and the two cases reported here, from the office of the chief medical examiner of New York City, give the necropsy results in two women who died directly following such insufflation. In both instances I was assured by the physician to whom this unfortunate accident occurred that he had insufflated numerous patients before, had previously never seen any untoward results, and had carried out the procedure in this fatally ending case in exactly the same manner as always. A pressure of 220 mm. of mercury was not exceeded in either case.
