Pulmonary embolism is the blockage of arteries in the lungs by blood clots which may be developed after 6-8 weeks of delivery. The blood clots first form in the legs and travel up to block the arteries of the lungs. The treatment involves injecting a small amount of a radioactive substance into a vein. This can happen to a woman who is pregnant for the second time. The procedure is safe during pregnancy because the dose of the radioactive substance is very small.
