Possibly. Unlike a placenta previa the vessels involved in a vasa previa are unlikely to erode away (which is how a placenta previa seemingly "moves"). There is a chance that this vessel will become thrombosed (plugged). This would take away the risk of fetal bleeding, but whether the baby would tolerate this depends on what proportion of the blood flows through this vessel.

Published data on vasa previa mortality shows a rate of 30-100%. Data suggests that survival is practically 100% if the diagnosis of vasa previa is made prenatally, and the patient is delivered by elective cesarean section. We have 2 prenatally diagnosed babies on record that died. However, they died of other complications of pregnancy such as prematurity and placenta previa. Vasa previa can be diagnosed prenatally. The time has come when physicians should look actively for it.

The theory about this that makes most sense is called Trophotropism. The easiest way to explain this is to make a comparison to a plant. A plant will lean towards the sun to get the light it needs to survive. Since the lower segment of the uterus is not as nourishing as the upper segment, the placenta will grow to reach more nourishing tissue. The placental mass will erode away from the cervix, but the vessels can't. This also explains the velamentous insertion of the cord.

Most likely the transverse lie is related to the low-lying placenta. When the placenta occupies the lower portion of the uterus, it prevents the head from engaging (going into the lower segment of the uterus, and the pelvis). Therefore, the baby may not be head first. The position of the vasa previa baby may also reflect an attempt by the baby to avoid compression of the velamentous vessels.

Vasa previa does have an association with a low-lying placenta, which may be associated with previous uterine surgery including prior cesarean, maternal smoking, multiple pregnancy (twins, triplets, etc), and also with assisted conception (artificial insemination, in-vitro fertilization, etc).

With a vasa previa not associated with abnormal placental implantation (some form of placental previa) there should be no increase in third trimester bleeding. Bleeding from a vasa previa only occurs if the vessel is torn or ruptures. No. There is nothing that we actively do to stop bleeding from a placenta previa. Bleeding from a placenta previa occurs because the attachment of the placenta to the uterus breaks (peels off).

Yes, velamentous cord insertion is also dangerous when the unprotected blood vessels are not crossing the cervix.

The answer to this is unknown. There are no lifestyle changes that affect the incidence of vasa previa. However, vasa previa does have an association with a low-lying placenta, which may be associated with prior cesarean, maternal smoking, multiple pregnancy, and also with assisted conception.

Though it is common to deliver with a VCI without detriment to the baby, VCI carries risk even when not a vasa previa. VCI may be allowed a trial of labor if the vessels are away from the cervix. However, close continuous monitoring is mandatory. The vessels could rupture, and also pressure on the vessels could lead to fetal compromise. This can be detected early by monitoring.

Yes. The pain of labor is something that can be controlled with relaxation techniques, medication, or by means of an epidural. You may also choose to practice Hypnobirthing, which is taught in a class prior to delivery. Any of these options are available in the Family Center to make your labor as comfortable as possible.

Certainly. We can email you copies of the design-in-progress or post it on our web server for you to view and download.

The exact reason is unknown. Higher levels of cortisone in the body during pregnancy may be an important cause of this improvement.

Becoming pregnant can be easier as you lose weight. Your menstrual cycle may become more regular. If you need to eat more while you are pregnant, the band can be loosened. After pregnancy, the band may be made tighter again and you can resume losing weight.

For most women gestational diabetes disappears immediately after delivery. However, you should have your blood sugars checked after your baby is born to make sure your levels have returned to normal. Women who had gestational diabetes during one pregnancy are at greater risk of developing it in a subsequent pregnancy. It is important that you have appropriate screening tests for gestational diabetes during future pregnancies as early as the first trimester.

Yes, you may, unless you have been directed by your physician not to (example; high risk for premature delivery). You should not start any new demanding exercises you were not doing prior to pregnancy. Your pulse rate should not go above 150 beats per minute and you should stay well hydrated. The activity should be low impact. A good rule of thumb is that you should be able to carry on a conversation while performing the exercise. Walking and swimming are good options.

More than half of pregnant women develop pregnancy gingivitis related to hormonal changes. The result is red, inflamed and tender gums that may bleed or be uncomfortable. The best way to try and prevent this is an effective oral care routine. And if you are planning to start a family go for a dental check up before you become pregnant.
