Apparent cornual occlusion in hysterosalpingography: reversal by glucagon

Abstract

In a series of 310 consecutive hysterosalpingograms, 24 patients were found with apparent cornual occlusion unrelated to prior tubal surgery. Glucagon administration (i.v.) was effective in reversing the obstruction in 9 (33%) of the 27 tubes. Of the occluded tubes that did not respond to glucagon, 80% were occluded at laparoscopy. Because cornual or isthmic spasm may be a cause of apparent cornual occlusion at hysterosalpingography, administration of glucagon is recommended before establishing the radiographic diagnosis of cornual occlusion.
