RECURRENT MASSIVE BLEEDING FROM AN INTERCOSTAL ARTERY ANEURYSM THROUGH AN EMPYEMA CHEST TUBE

Intercostal artery aneurysms can be of congenital, post-traumatic, or mycotic type. Intercostal arterial aneurysmal bleeding can be brisk enough to lead into shock or sudden death. Bleeding through chest tubes has been reported due to various causes; it is commonly due to injury to intercostal or pulmonary vessels and is occasionally due to leaking aortic aneurysms. We describe a patient who had development of repeated episodes of brisk bleeding through an empyema chest tube leading to shock episodes requiring resuscitations. After extensive search, the bleeding source was found to be an intercostal artery aneurysm. Transcatheter embolization of that intercostal artery with absorbable gelatin sponge (Gelfoam) was successful in obliterating the blood flow to the aneurysm and in preventing further bleeding.
