What is the result of abnormal VQ scan if pulmonary embolus?

What is the result of abnormal VQ scan if pulmonary embolus?

VQ scan...: There are 2 parts to a VQ scan: ventilation and perfusion. If there is a clot present, the scan will show that areas of the lung are being ventilated but not perfused. In other words, the clot is preventing blood flow in an area that is being ventilated. This is the classic finding for a pe in a VQ scan but not all scans are that clear-cut so additional testing is sometimes needed. ...Read more

Unprovoked pulmonary embolism. Small low burden. Been on thinners for 4 months absolutely NO risk factors. Should I come off?

Unprovoked pulmonary embolism. Small low burden. Been on thinners for 4 months absolutely NO risk factors. Should I come off?

It depends: A pulmonary embolus triggered by surgery or a mild risk factor such as estrogen therapy, long-distance travel, non-surgical hospital stay may be treated for 3 months, rather than 6 or 12 months. A pulmonary embolus that was unprovoked is treated for 6 to 12 months or long-term. You should consult with your doctor for a specific recommendation. Good luck.

Can a low heart cause pulmonary embolism?

Can a low heart cause pulmonary embolism?

No: I'm guessing that you mean a heart that lays low in the chest. This would not cause pulmonary embolism; in fact the position of the heart would have no effect on pulmonary embolism, which is caused by clots in veins (usually in the legs or pelvis) breaking loose and traveling to the lung. ...Read more

Why will a pulmonary embolism cause low o2 but not high co2?

Why will a pulmonary embolism cause low o2 but not high co2?

V/Q mismatch: A large pe will cause elevated c02 and require more respiratory effort because the physiologic "dead space" will increase and the body may not be able to compensate with increased breathing. For the same reason the affected area of lung cannot participate in gas exchange which may lead to inadequate oxygenation - or low o2. ...Read more

After having a pulmonary embolism, is being short of breath normal when your INR is low?

After having a pulmonary embolism, is being short of breath normal when your INR is low?

Not really: You may be short of breath after pulmonary embolism (pe) due to residual clot in the pulmonary arteries if you get recurrent episodes of shortness of breath you may be having recurrent pe. This may occur especially if your inr is not maintained in the therapeutic range. This is not normal and requires further evaluation. Tell your physician! ...Read more

After having a pulmonary embolism, is it normal to be short of breath if your INR is low?

Depends: If you have had a large pe, it is normal to be short of breath for a few weeks or months as you recover, no matter what your INR is. If you have been ok with a therapeutic INR but now you are short of breath with a low inr, have yourself checked, or get some Lovenox or Arixtra shots while you are adjusting your Coumadin (warfarin) to a desired inr. ...Read more

Should warfarin be continued for six months if pulmonary embolism as a result of ocp?

Yes: As dr. Milstone said, the recommendation is that someone take warfarin for at least 6 months after being diagnosed with a pe. After stopping the warfarin, there is recently published evidence that taking low dose Aspirin for two years can help to prevent your getting another blood clot. ...Read more
