Nonisthmic communicating uteri. Report of 3 new types in a new subclass of communicating uteri.
OBJECTIVE
To describe 3 new malformations and propose a new subclass of malformations, nonisthmic communicating uteri.


METHODS
Review of 17,511 hysterosalpingograms revealed 19 cases of communicating uteri. Three cases were identified that showed nonisthmic communications, previously unreported.


RESULTS
The 3 new types of communicating uteri were (1) bicornuate uterus with 2 sites of communication, midcervical and isthmic; (2) septate uterus with a midcorporeal communication; and (3) bicornuate uterus with a low cervical communication and atretic hemicervix.


CONCLUSIONS
The 3 new types of nonisthmic communicating uteri constitute a new subclass of communicating uteri. We are aware of only 1 other reported type of nonisthmic communicating uteri. Nonisthmic communications may arise from a different mechanism than isthmic communications.
