I have. My wife had a deep vein thrombosis while carrying my son that resulted not only in her throwing an embulis to her lung, but it completely decanualized the veinous system in her left leg as well. Until she had a tubal done (in a catholic hospital, choke on that) I (we) lived in absolute fear every time a condom broke.
I'm sorry about that, but there isn't a necessary causal relationship. Pregnant women simply have a higher risk of developing DVT, as described below.
Deep Vein ThrombosisUntil she had a tubal done (in a catholic hospital, choke on that)Did you know that, according to the National Institutes of Health, two million Americans annually develop a condition called deep vein thrombosis (DVT)? You've probably heard of someone who has had this condition, or perhaps you have the painful experience of blood clots in your own legs. A significant number -- six hundred thousand -- of DVT patients also develop a pulmonary embolism. For an alarming sixty thousand patients who develop a pulmonary embolism each year the condition is fatal.
According to the National Heart, Lung, and Blood Institute, the formation of blood clots in the legs is a rare but serious complication that has frequently been associated with the use of birth control pills. Until recently, low-dose estrogen replacement therapy in post-menopausal women was believed to be free of this rare complication.
The good news for most women is that the actual risk of hormone-induced DVT remains small, perhaps being outweighed by the potential benefits of estrogen replacement for treating the vasomotor symptoms (hot flashes, night sweats) of menopause, as well as the other benefits of estrogen such as reducing the risk of osteoporosis and heart disease . However, the use of estrogen as a preventive measure against heart disease is clearly one that is still under study and highly debatable; the American Heart Association recently came out against the use of estrogen if the primary purpose is to prevent heart disease.
...Hormonal factors are not the only cause of blood clots in the legs. Other causes of DVT include:
Poor circulation caused by conditions such as a recent heart attack or stroke, or other forms of heart disease.Who Is Most at Risk of Developing DVT?Varicose veins.
Long-term inactivity.
Extended bed rest.
DVT can also occur during a long flight when passengers often have little room to move their legs. This condition is known as 'Economy Class Syndrome.' Certain people are considered most at risk for in-flight DVT; these people include pregnant women, people who are overweight, those whose feet do not touch the floor, older passengers, smokers, and people with coronary artery disease or certain blood conditions. To prevent DVT from occuring during or after an airplane flight, it's recommended that passengers try to get up and walk up and down the aisle at least once an hour.
An injury to a vein can bring on an occurrence of deep vein thrombosis. A vein can be injured in several ways including a blow to the leg, surgery, or radiation treatments for cancer. Such an injury can cause a narrowing or blockage in a vein where it then gathers blood and clots.
Pregnancy increases the risk of DVT developing because of the body's natural tendency to prevent excessive bleeding during childbirth.
Other potential causes include severe infection, liver disease, and some forms of cancer.
People who are elderly and those who are obese experience the highest rates of deep vein thrombosis; however, this in no way means that healthy, young individuals have nothing to worry about. Certain people, born without important blood thinning properties, are always at an increased risk for developing blood clots.
You mean a nominally Catholic hospital.
I (we) lived in absolute fear every time a condom broke.
You would have been less fearful if you used NFP.
And simple measures can be taken to avoid DVT, such as wearing compression hosiery. Effective drugs are also available for women at high risk of DVT during pregnancy.
