Trial of Labor?

I am taking care of a 37 yo G3/P2 now at 18 weeks gestation who had a primary cesarean section in her first pregnancy without a trial of labor based upon clinical pelvimetry. This was done in Switzerland. She then moved to Norway, had a second pregnancy and she had x-ray pelvimetry performed. She was counseled against a VBAC. So she had a repeat C/section.

She is Irish, 5'2" tall, married to a North American who is about 6 feet tall. 1st baby weighed 8#, 2nd baby 7 1/2#.

She denies ever having had a motor vehicle accident or fracturing her pelvis. She has no abnormalities of the spine (such as scoliosis). I didn't perform her intake visit in our office; I have yet to perform "clinical pelvimetry". Both C/sections were low transverse uterine incisions.

Apart from one patient with a history of a motor vehicle accident with pelvic fracture and documented abnormality of the bony pelvis, and one patient with short stature 4'10" with a large baby, I have never outright done a primary c/section without a trial of labor. I have done a few successful VBACs in patients with 2 prior c/sections.

Anybody want to hazard a guess at what the Swiss doctor was thinking? How about the Norwegian doctor? The patient and her husband want "what's best for the baby." My inclination is to perform clinical pelvimetry at term, offer a trial of labor if appropriate; if there is arrest of dilation or descent with good contractions then go to c/section.

Any comments?

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
