How dangerous is C-section with placenta previa? I have heard there is a high risk of bleeding out!?

Increased risk.: What you have heard is correct; exsanguination can occur in undiagnosed accreta/previa in small hospitals with inexperienced surgeon(s). Seek expert care if uou have placenta previa (including maternal-fetal medicine ultrasound and consultation), avoid all nsaids/sex/travel/unnecessary car rides/heavy lifting/straining/constipation and deliver in a large, tertiary care hospital [blood bank/icu]. ...Read more

Having a c-section for placenta previa. Was told to get to hospital 3 hours ahead to get prep for surgery. What will they do? What takes so long?

Having a c-section for placenta previa. Was told to get to hospital 3 hours ahead to get prep for surgery. What will they do? What takes so long?

It always takes time: Any planned surgery takes time: there's paperwork, a pre-anesthesia evaluation, a monitor strip of your baby's heartbeat, prepping the site of surgery, etc. In addition, you must remember that with ob, you may be at the "mercy" of other situations with greater urgency. For example, if the need for an emergency c-section arises for another patient, they'll go first - as is appropriate. Good luck. ...Read more

Do most woman survive c sections with placenta previa? I am 32 weeks with a complete previa and very scared baby/i wont make it through the surgery?

See below: This operation does carry some risk to you and the baby. The surgical and anesthesia team will be prepared for these eventualities. You need to be at a hospital that has a high-risk OB unit and can manage this issue. ...Read more

I'm O+, my husband is AB+. What's the likelihood of our baby having neonatal anemia? High risk pregnancy w/ maternal anemia and planned c-section cutting through anterior placenta previa.

I'm O+, my husband is AB+. What's the likelihood of our baby having neonatal anemia? High risk pregnancy w/ maternal anemia and planned c-section cutting through anterior placenta previa.

Possible: There is some possibility of an A/O or B/O reaction with jaundice and hemolytic disease but that part of this is usually minor and easy to manage. An OB with quick hands can limit the other issue. I would try to relax and figure out what your life will be like with 3 kids running around. ...Read more

Placenta previa is a must have c section, is this true?

Placenta previa is a must have c section, is this true?

Yes: In almost all cases, some cases though with partial type or just the tip of placenta reaching the cervix and go into labor proceed without that horrendous bleeding, very rare, in these days with all the advances in diagnostics, medications, anesthesia and surgery, no one would take chances, for the safety of the mother and baby , ...Read more

Diagnosed with marginal placenta previa at 23 wk. Now 26 wk. MD said I will need a c section. Is there any chance the previa will still resolve?

Perhaps: If a previa is present at the time of labor then a c section will be needed. Typically marginal previas are monitored by serial ultrasounds. As the uterus grows the placenta may be pulled safely away from the cervix. Ask your doctor if other sonograms will be done ...Read more

Can full placenta previa actually resolve itself if diagnosed at around 12 weeks? It'd my 2nd preg& I am scheduled for c-section anyway.

Can full placenta previa actually resolve itself if diagnosed at around 12 weeks? It'd my 2nd preg& I am scheduled for c-section anyway.

Yes, >90% of time.: I don't even look at the placenta before 14-16 weeks because it is frequently previa without any significance clinically. If it covers the internal cervical os and overlaps by at least 2.5 cm in all directions (one inch) at the anatomy scan (18-22 weeks), then it shall persist as previa at delivery with 99% certainty. If it is >2 cm away from the os at term vaginal delivery is feasible 63% of time. ...Read more

Anterior placenta previa with placental lake seen at 28w ultrasound, 2 D&Cs & no c-section hx. Any risk of placenta accreta? Best time to deliver?

Placenta Previa: Placenta previa occurs when the placenta is covering the opening of the cervix. Vaginal delivery is possible in mild cases of previa. Placenta accreta is a different condition where the placenta gets "stuck" to the uterus. While the risk of accreta increases when you have previa, that risk is low if you have never had a c-section before. Follow-up with your obstetrician regarding delivery dates. ...Read more
