A wandering bullet. Successful removal and a simple technique to prevent its migration

Bullet migration toward and within the pulmonary circulation occurred in a case of gunshot wound to the right upper abdominal quadrant. Difficulties in locating the missile were encountered during surgical attempts to remove it. Finally, a Swan-Ganz catheter was used for pulmonary angiography. The balloon of the catheter was inflated to prevent further migration of the missile until it could be surgically removed.
