A 38 week pregnant primigravida with breech presentation is found to have cord prolapse. LEAST chances of cord prolapse are seen in:
Umbilical cord compression and prolapse may be associated with breech delivery, paicularly in complete (5%) and footling (15%) presentations. This is due to the inability of the presenting pa to fill the maternal pelvis, either because of prematurity or poor application of the presenting pa to the cervix so that the umbilical cord is allowed to prolapse below the level of the breech. Frank breech presentation offers a contoured presenting pa, which is better accommodated to the maternal pelvis and is usually well applied to the cervix. The incidence of cord prolapse in frank breech is only 0.5% (the same as for cephalic presentations). Ref: Kish K., Collea J.V. (2007). Chapter 21. Malpresentation & Cord Prolapse. In A.H.
