Catheter-Induced Pulmonary Artery Dissection and Contrast Extravasation During Pulmonary Angiography

Pulmonary artery injury during pulmonary angiography is an uncommon complication. We describe two cases of iatrogenic pulmonary artery extravasation that resulted from the use of pigtail catheters for pulmonary angiography. No further complications occurred and no treatment was necessary in either case. Thus, mild contrast extravasation appears to be a self-limited complication that likely requires little more than short-term observation.
