If you get appendicitis while on Coumadin (warfarin) can they still do surgery? Is the surgery more risky from the chance of bleeding?

If you get appendicitis while on Coumadin (warfarin) can they still do surgery? Is the surgery more risky from the chance of bleeding?

Surgery can be done: In cases in which patients are anticoagulated with warfarin and need emergent surgery fresh frozen plasma transfusion and vitamin K can be used to reverse the anticoagulation effect by warfarin and decrease bleeding during and after surgery resulting from warfarin treatment. Every time there is a higher chance of bleeding there is a higher chance of adverse events and risk to the patient. ...Read more

Which type of specialist would i see if i've had 2uedvts and want to get pregnant? On warfarin for life, need prescription for heparin.

A perinatalogist. : A perinatalogist takes care of women with very high risk pregnancies which is what yours would be. You also want the doctor taking care of your warfarin involved. It would be helpful to do a consult visit with a perinatalogist prior to pregnancy to make sure you are informed of the risks and have a plan in place for when you get pregnant. Good luck. ...Read more

Could i stop warfarin for 2 weeks each cycle when ttc and start lmwh if i get pregnant? Surely a DVT couldn't form again in such a short time?

Could i stop warfarin for 2 weeks each cycle when ttc and start lmwh if i get pregnant? Surely a DVT couldn't form again in such a short time?

NO!: You are playing with danger by changing your Coumadin (warfarin) and yes DVT can form in a short time. Each day airline passengers flying from the us to europe exit the air craft with DVT formed during flight. Some require hospitalization. Coumadin (warfarin) requires certain range levels to be effective; some patients require days of therapy to attain therapeutic levels. Discuss with your physician before changes. ...Read more

Warfarin is teratogenic to a fetus. So why would my thrombosis specialist tell me to switch to lmwh only when i get pregnant and not before? Confused!

Warfarin is teratogenic to a fetus. So why would my thrombosis specialist tell me to switch to lmwh only when i get pregnant and not before? Confused!

Days of exposure: I'm assuming that your doctor knows you will take a pregnancy test as soon as you miss a period and that your periods are regular. There's no harm in switching to lmwh before conception, if you feel strongly, you can suggest that. The 2012 accp guidelines only 'weakly' suggest switch from warfarin --> lmwh after conception. There's absolutely no problem on lmwh while trying to conceive. ...Read more

My thrombosis specialist is having me switch from warfarin to lmwh as soon as i get a positive pregnancy test. At 4 weeks, is this ok?

Yes!: Warfarin is not good to take during pregnancy as it can cause birthdefects, lmwh does not have this problem and can be safely used during pregnancy. I would strongly suggest that you seek an opinion from an OB or highrisk pregnancy doctor to be sure you are doing all that they would recommend to have a healthy pregnancy. ...Read more
