Summary: If you have a brain aneurysm and are planning a pregnancy, it’s a good idea to talk beforehand with the specialist monitoring your aneurysm (vascular neurosurgery or endovascular therapy) and your obstetrician-gynecologist, in a coordinated manner. Together, they can review the aneurysm’s features, your medications, and your medical history to plan follow-up, because the risk is not the same for every patient.
Many women discover by chance that they have a brain aneurysm during imaging done for another reason, and then wonder what it means for a pregnancy they are planning. An unruptured aneurysm is a weak, bulging area in the wall of an artery in the brain that has not bled. It’s a good idea to coordinate a discussion among your specialists before trying to become pregnant or, if you are already pregnant, during your follow-up care.
Which specialists should be involved in planning?
At a minimum, your care team should include the specialist monitoring or treating your aneurysm and your obstetrician-gynecologist. Depending on your situation, an anesthesiologist and the doctor managing your blood pressure or other conditions may also be involved.
The vascular neurosurgery or endovascular therapy specialist knows the aneurysm’s size, shape, and progression. Your obstetrician-gynecologist knows your reproductive health and will guide your pregnancy; if it is considered high-risk, a maternal-fetal medicine specialist may be involved. This subspecialty focuses on pregnancies that require special monitoring. The important thing is for them to communicate with each other so you are not the only one passing information along.
What information should be shared between neurosurgery and obstetrics?
Both teams need to know the aneurysm’s characteristics, its progression, any previous treatment, and your medications. With this information, they can plan pregnancy monitoring without making decisions on the fly.
Bring copies of the following to each appointment:
- •The report and images from your most recent imaging study (the aneurysm’s size, location, and shape).
- •The date of your last follow-up and whether there have been any changes.
- •Any treatment you received, if applicable: a clip, coils, or a stent.
- •Your medication list, blood pressure readings, and smoking habits.
- •A family history of aneurysm or brain hemorrhage.
Does pregnancy carry the same risk for every patient with an aneurysm?
No. Risk depends on the aneurysm’s features and your overall health, so two women with an aneurysm may receive different recommendations. It’s best not to compare yourself with other patients.
The NINDS (U.S. National Institute of Neurological Disorders and Stroke) identifies aneurysm growth, size and location, a previous rupture, and family history as risk factors for rupture; it also highlights high blood pressure and smoking. When making a decision, your doctor also considers your age, health, and medical history.
What about follow-up imaging and medications?
It’s a good idea to plan for both before pregnancy. Some aneurysm imaging studies use radiation or contrast material, and some medications need to be reviewed; adjusting them is a decision for your doctors, not something to do on your own.
RadiologyInfo reminds patients to always report if they are pregnant, because many X-ray studies are avoided during pregnancy and precautions are taken if they are necessary. MedlinePlus advises telling the surgeon if you are or could be pregnant before aneurysm repair. Do not stop or start medications without medical advice.
What symptoms require emergency care during pregnancy?
A sudden, severe headache, nausea or vomiting, neck stiffness, confusion, double vision, weakness, or loss of consciousness require calling 911 immediately, without waiting for your prenatal appointment.
MedlinePlus explains that a ruptured aneurysm is a medical emergency. When you arrive, tell them you have a brain aneurysm and are pregnant, and bring your report if you can. Do not attribute these symptoms to pregnancy without an assessment.
Frequently asked questions
Does having an unruptured aneurysm mean I can’t get pregnant?
Not necessarily. The decision is individual and depends on the aneurysm’s features, your health, and your medical history. Your team will explain the risks and options, and you will take part in the decision, with your partner’s support if you wish.
Should I have my aneurysm treated before I get pregnant?
It depends on the case. Some small aneurysms are only monitored, while others are treated before they can rupture. The specialist weighs the risk of rupture against the risks of treatment and discusses your options so you can decide together.
Who decides how the baby will be delivered?
The obstetric team, using information from the aneurysm specialist and anesthesiology, and with your participation. There is no single delivery method for all women with an aneurysm; it is determined based on your situation and how the pregnancy progresses.
What should I ask before trying to become pregnant?
If you develop a sudden, severe headache, vomiting, or weakness at any time, call 911 first. For planning ahead, ask your team:
- •Does my aneurysm need imaging or an assessment before I try to become pregnant?
- •How will neurosurgery and obstetrics communicate, and who will coordinate follow-up?
- •Which medications should I review before getting pregnant, and who will decide whether they need to be adjusted?
To prepare your questions, you can learn more about what it means to find a brain aneurysm and asking for a second opinion.
For non-urgent questions or to request an individual assessment, you can contact the office.
