To the Editor: Re "Trying to Avoid 2nd Caesarean, Many Find Choice Isn't Theirs" (front page, Nov. 29): I do not believe that the issue of whether a vaginal delivery can or should be performed in a pregnancy after a prior Caesarean should be framed as a matter of a woman's right to choose. It is perfectly reasonable for a hospital or a doctor to decide not to offer this service because it is felt to be too risky and the patient who desires it would be better served in a tertiary care center where obstetric complications are more routinely...
