On women and blood clots

The National Blood Clot Alliance alerted me to two things today, through a news release:

  1. May 14 – 21 is National Women’s Health Week in the US, something that the HHS started a while ago. Who knows how long it will last, and perhaps maybe we should turn this into a regular thing sans government impetus, going forward.
  2. There is a risk to blood clots for women from many forms of hormonal birth control, which they should be aware of.

Clot Risks

It is true that women suffer from clot risks throughout their life. The risk is lower for younger women, compared to older women. Even considering contraceptive use it is low. Please see the NIH reference below. The use of contraceptives does increase this risk in women of child bearing age, and the consequences of blood clots include both morbidity and mortality, and therefore, it is important that there is ample awareness of these risks.

Creating Awareness

The National Blood Clot Alliance along with  Alexandra L. Rowan Memorial Foundation, another excellent organization I learned about today, are asking women to visit “Women And Clots”, a website, womenandbloodclots.org to learn more, access resources and use a risk assessment tool to learn more.

Please pass this on to women you know, especially of child-bearing age, so they may learn of and benefit from this resource and be aware of clot risks going forward!

And, I plan to blog as profusely as time permits during National Women’s Health Week. So consider subscribing to the Blog updates and watch this space for more!

No, one pregnancy does not make Mirena or other IUDs useless

It is important to remember that the best source of advice is your Obstetrician/Gynecologist/Doctor, and regardless of all your research, you should always consult them for medical advice! 

The Backstory

Always on the look out for interesting medical device news, I came across this apparently humorous story of a baby, born through a pregnancy that occurred about 3 weeks (this is only an assumption based on what the mother herself has predicted) after the placement of a Mirena IUD.

The humor supposedly lies in the fact that the Obstetrician fished out the IUD, which was difficult to find and remove during the pregnancy, while the C-section was being performed. A nurse then put the IUD on the baby’s hand and captured an image with one of the ubiquitous smartphones, shared it, and the image then went “viral”.

What Ensued

Due to stiff competition among manufacturers and variable experiences from patients, Mirena, and IUDs in general, are discussed on and off, with their capabilities challenged. An incident such as this pregnancy always bring up questions, many fair, and many not. It is important that they be addressed, nevertheless.

I have always maintained, even in my earlier blog posts (one is linked below) on my main Medical Devices blog, that IUDs are the easiest and least invasive ways to prevent pregnancies, when compared to other devices.

Planned Parenthood appears to claim that IUDs are 99.9% effective. Now, I would be cautious even with the force of Planned Parenthood behind the statement. A pregnancy that was already initiated, hormonal imbalances or physiological oddities, improper placement, any number of things could potentially cause a pregnancy.

Even with both partners exercising birth control measures, you could still have a pregnancy!

Some Caution for Device Designers

People see the humor in the situation, but a health practitioner and a device designer/engineer should see something worrisome here. Of course, reporters (link below), don’t always know how to accurately represent information, but I find this particular sentence of concern:

The doctor was unable to remove the implant during her pregnancy, but while delivering the baby, Hellein said he found it behind her placenta.

Note: Hellein is the mother.

There are at least one of two things going on:

  1. It was simply difficult or impossible to remove the IUD during the pregnancy.
  2. It is possible that it was impossible to remove the IUD because it could not be found!

Understandably possibility no. 2 is quite worrisome. Without knowing much though, I cannot tell whether the IUD needs to have features that make it obvious during an X-Ray, Ultrasound or other imaging technique, preferably, an imaging modality whose radiation levels don’t present risks to mother or child.

Opportunities and Challenges

If the IUD is difficult to find due to anatomical challenges, whether they arise from a pregnancy or not, there is an opportunity to improve the design of IUDs. What form this might take is hard to say, and one thing to consider is, that the methods that help make the device visibility should be biocompatible and should in no way threaten the patient or any potential babies.

Further Issues

Here is something else from the article that gives me pause:

“This woman is very lucky that when the placenta grew over the IUD it did not disrupt the blood flow to the placenta,” Ghasseminia said.

She said this could lead to a miscarriage.

Laura Ghasseminia, is apparently a Planned Parenthood nurse practitioner, interviewed for the story by 10 News (link below). What she said here, gives one further pause. It is difficult to conceive, but it could be possible to design an IUD that  somehow loses flexibility or its shape once it dislodges from its location, whether due to a fertilized fetus, or due to some other reason.

All said, there are some challenges that this pregnancy and the “miracle baby” have unearthed, and this requires further consideration!
