Angiography > Exams & Procedures > Pulmonary Embolization

This is a venous procedure to stop blood flow into abnormal pulmonary vessels, such as HHT patients. Local anaesthetic is given to numb the area in the groin region. A small thin tube called a catheter is inserted into a vein, normally the femoral vein, to best view the veins supplying the lungs. A contrast medium is injected through the catheter. Once the abnormal blood vessel is identified, metal coils are placed to stop blood flow to that area.

This procedure can take several hours. Once the radiologist has completed the procedure, he/she will apply pressure to the puncture site for five minutes. You will spend the night in hospital for observation.
