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?

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

Placenta Blocks Cervix (Definition)

A previa is when a placenta entirely covers the opening of the cervix into the uterus (internal os). It is a reason for a cesarean section and if bleeding occurs and stops it may be a ...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

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

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

Doctor said that my placenta is attached near to my cervix. Is that means I can have placenta previa? Is that means c-section? I'm only 5months.

Doctor said that my placenta is attached near to my cervix. Is that means I can have placenta previa? Is that means c-section? I'm only 5months.

Too soon: At 5 months, it's too soon to say if your placenta will still be attached near your cervix when you are near to term. Sometimes, when the placenta is adjacent to or bordering the cervix at 5 months, the uterus grows and the placenta is far enough away at the time of delivery from the cervix that you can safely have a vaginal delivery! ...Read more

I had a 2nd csection 10 weeks ago (previous was 2 years ago). During surgery they found I had placenta previa & had to cut through the placenta.  i h?

What is the question: I do not know what your situation was, but almost always placenta previa should be diagnosed before you had the csection by an ultrasound, all of my pts get at least 4 ultrasounds, the last one being 34-36 weeks which also checks the location of the placenta, because if u had a previous csection a placenta previa can often cause a placenat accreta which can cause big problems, glad u did ok. ...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.

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

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

I am 29 weeks pregnant with complete placenta previa. My baby is in a transverse position. Will this complicate the c-section?

I am 29 weeks pregnant with complete placenta previa. My baby is in a transverse position. Will this complicate the c-section?

Not much: Ob/Gyns are trained for both a transverse lie and a complete placenta previa at the time of c/section. Extra care and some additional maneuvers are needed to deliver the baby but this is not a big deal usually. However, if you have had a previous c/section and now have a previa much more major complications can arise if the placenta is over your old scar. Best wishes! ...Read more

Hello I have found out that I have complete placenta previa I'm 14 weeks pregnant is there any chance this will go away I don't want a c section?

Placenta previa: Yes this can go away. Placenta previa is the condition in pregnancy when the placenta lies over the cervix. It may be present in early pregnancy but can move away from the cervix later o. Repeat ultrasounds closer to delivery will check to see where the placenta is. Bleeding at any time during pregnancy is worrisome, and if it happens notify your doc right away. ...Read more

My ob says that having posterior marginal placenta previa is good news rather than it being anterior. Is that true?

Yes: Placenta previa is never good news, but the cesarean delivery is easier if we don't need to deliver through the placenta. An anterior placenta previa for someone with a previous cesarean section can be a very difficult delivery.
You will want to recheck the placenta position closer to term if this was seen on an early sonogram. ...Read more

What kind of incision for delivery of singleton in transverse lie with anterior placenta previa? Will low transverse cut risk hemorrhage/uterine tear?

What kind of incision for delivery of singleton in transverse lie with anterior placenta previa? Will low transverse cut risk hemorrhage/uterine tear?

Hyst'omy MANDATED: Hello Annie-_777
I am not an OB GYN but I have had a lot of experience which tells me that a lower abdominal incision (Pfannen-Stiel) is a better incision in almost all situations. This situation of a transverse lie and an anterior placenta praevia is a very hazardous situation because you need the baby out and the cord clamped within seconds of opening the uterus so choose a very skilled surgeon. ...Read more

With anterior complete placenta previa and 2 bleeds (1 warning, 1 massive) what are the chances of the placenta shifting with the uterus after 24wks? And possible cause of constant dull aches and jolts in pelvis area. Also have short CX

With anterior complete placenta previa and 2 bleeds (1 warning, 1 massive) what are the chances of the placenta shifting with the uterus after 24wks? And possible cause of constant dull aches and jolts in pelvis area. Also have short CX

MFM evaluation: Consider asking for a referral to a maternal fetal medicine specialist. Your situation sounds quite high risk especially when you use phrases like massive bleeding. Your doctor may want to consider keeping you in the hospital now that the baby has reached viability. The chances of previa resolution will vary depending on the exact location and will vary from person to person ...Read more

2nd csection 10 weeks ago where had placenta previa & had to cut through after doing abdominal exercises today my scar started burning on right side.?

Probably no problem: The abdominal muscles may burn with exercise for a while after surgery. If not too uncomfortable you may continue to exercise. I tell patients they may begin abdominal exercises 6 to 8 weeks after a cesarean section. If you have redness, drainage, or bulging at the incision site call your obstetrician. ...Read more

15 weeks and just diagnosed with placenta previa. Should I be worried?

Can you have sex with a placenta previa?

Can you have sex with a placenta previa?

Be cautious: No! A placenta previa can be dangerous and result in heavy bleeding. Anything that could disturb the previa should be avoided, like sex, fingers, really anything in the vagina. A previa can resolve over many weeks, so make sure your doctor is checking to see if it is still there. Until then, I would wait.

Good luck!

Can placenta previa be corrected with bed rest?

Can placenta previa be corrected with bed rest?

Not really.: If the diagnosis of placenta previa is made before 20 weeks, some women experience resolution of the morbid placental implantation with time - bedrest is not correcting the problem. As the uterus and the fetus grow, they pull on the placenta and stretch the lower uterine segment to "move" the placenta out of the way and allow for vaginal delivery at term. ...Read more

How does placenta previa cause preterm delivery?

Bleeding and Cntrxns: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US. ...Read more

If I have placenta previa, will I be put on bed rest?

No: Placenta previa includes partial or complete coverage of the cervix by the placenta. Bedrest is not necessary unless there is vaginal bleeding or persistent preterm labor. If vaginal bleeding is experienced, you will often be evaluated in the hospital with ultrasound and eventually released home to bedrest for awhile. ...Read more
