a Pulmonary artery angiography, right anterior oblique view 33o, showing small outpouching (arrowhead) from a subsegmental branch in the lateral right lower lobe. b The subsegmental branch was selected, and contrast actively extravasated into an adjacent airspace (arrowhead), at which point the patient also developed 250 cc of frank hemoptysis during the procedure. c Embolization was achieved using Nester coils (Cook, Bloomington, IN) and Amplatzer Vascular Plug II (St. Jude Medical, St. Paul, MN), with no further filling of the pseudoaneurysm.
