Full Answer

When a blood clot breaks loose and travels to the lungs, it is known as a pulmonary embolism. Some people who experience a pulmonary embolism die immediately, while others may die a short time afterwards when the body is unable to get needed oxygen. Blood pressure collapse can also occur with a pulmonary embolism, causing death, notes eMedicineHealth.

In people who experience pulmonary embolism who survive initially and receive needed emergency treatment, the prognosis is greatly improved, states eMedicineHealth. Hospitalization for a few days to make sure the blood is thinned adequately may be required. Medication for thinning the blood may need to be taken for six months or even longer following a bout with pulmonary embolism. Some people may need to take this type of medication for life.

Another option is to have a filter inserted surgically into the vena cava, according to eMedicineHealth. The filter keeps large clots from reaching the lungs and can be removed later on if necessary. Candidates for a filter placement include patients who require surgery or are unable to take blood thinners.
