Angiogram of the Lung

Lung Angiogram, Pulmonary Angiogram

Risks

The chance of any major problem from an angiogram is very small, but some problems can occur. In most cases the problems occur within 2 hours after the test when you are in the recovery room. If the problem occurs during the angiogram, the test may not be completed. You may need urgent treatment that could include surgery.

• There is a small chance of developing an abnormal heartbeat. This usually lasts only a few seconds and goes away without any other treatment.
• There is a chance of an allergic reaction to the iodine dye. The reaction can be mild (itching, rash) or severe (difficulty breathing or sudden shock). Most reactions can be treated with medicines. Be sure to tell your doctor if you have hay fever, asthma, or iodine allergy or food allergies.
• There is a small chance that the catheter may damage a blood vessel or dislodge a piece of clotted blood or fat from the vessel wall. The clot or fat can block blood flow to the brain, arm, leg, or intestine (bowel).
• Bleeding from the needle site may occur. Also, a blood clot can form where the catheter was inserted. This may cause some blockage of the blood flow to the arm or leg.
• The iodine dye used for the test can cause water loss or direct damage to the kidneys. This is a special concern for people who have kidney problems, diabetes, or who are dehydrated. Special measures are used during the test to prevent problems for people who need an angiogram and have these conditions.
• There is always a small chance of damage to cells or tissue from being exposed to any radiation, even the low level used for this test.
