Pulmonary angiography

There is the possibility of significant risk associated with pulmonary angiography. There is a possibility of a reaction to the contrast medium. There is some risk of the catheter damaging the vein and a blood clot traveling to the lungs and causing an embolism. A clot or excessive bleeding at the puncture site may result in a partial blockage of the blood flow to the leg.

There is low radiation exposure. X-rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits.

Pregnant women and children are more sensitive to the risks of X-rays.
