Intercostal artery aneurysms can be of congenital, post-traumatic, or
mycotic type. Intercostal arterial aneurysmal bleeding can be brisk en
ough 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 repeat
ed 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. Transc
atheter embolization of that intercostal artery with absorbable gelati
n sponge (Gelfoam) was successful in obliterating the blood flow to th
e aneurysm and in preventing further bleeding.
