The woman was diagnosed as genital warts in vagina and uterine cervix in the early pregnancy. She was treated and now the genital warts was not found in vagina and uterine cervix. Can she give birth by vaginal delivery?
For unknown reasons, genital warts frequently increase in number and size during pregnancy.
Acceleration of viral replication by the physiological changes of pregnancy might explain perineal
lesion growth and progression of some to cervical neoplasm These
lesions may sometimes grow to fill the vagina or cover the perineum, thus making vaginal delivery orepisiotomy difficult. Because HPV infection may be subclinical and multifocal
, most women with vulvar lesions also have cervical infection, and vice versa
longterm follow-up studies are consistent with a very low vertical transmission risk.
The benefit of cesarean delivery to decrease transmission risk is unknown, and thus it is currently not recommended solely to prevent.
When large or spread out, genital warts can complicate a vaginal delivery. In cases where there are large genital warts that are blocking the birth canal, a cesarean section may be recommended. Infection of the mother may be linked to the development of laryngeal papillomatosis in the newborn.
during pregnancy ,The vaginal walls undergo striking changes in preparation for the distention and increased elastic fiber that accompanies labor and delivery.
The considerably increased volume of cervical secretions within the vagina during pregnancy
The rise in maternal circulating relaxin levels also during pregnancy, increased vascularity and hyperemia develop in the skin and muscles of the perineum and vulva, with softening
of the underlying abundant connective tissue.
Risk factors for lacerations include:
nulliparity, shoulder dystocia maternal position or the use of perineal massage during second stage.
used to guide and control the fetal head to avoid expulsive delivery. Slow delivery of the head decrease lacerations. Perineal techniques during the second stage of labour reducing perineal tears .
