Acute pulmonary edema from unrecognized high irrigation pressure in hysteroscopy: a report of two cases

After two consecutive patients underwent hysteroscopy that was complicated by pulmonary edema, the pneumatically inflated pressure cuff machine was checked and found that the pressure gauge was in error, with actual pressure being twice that of the recorded number. High irrigation pressures with a seemingly normal amount of irrigation fluid may induce acute pulmonary edema.
