Ruptured aneurysm of the ductus diverticulum into the pulmonary artery in a man: A successful repair

Aneurysm of the ductus diverticulum in the adult is rare and its rupture is fatal. A 75-year-old man presented with congestive heart failure that sudd enly occurred with a continuous murmur. Angiography showed a left-to-right shunt through a large thrombosed aneurysm of the ductus diverticulum (6 cm) , and the pulmonary-to-systemic flow ratio was 2.6. Patch closure of the or ifice (3 x 4 cm) of the aneurysm and repair of the perforated pulmonary art ery were done emergently under hypothermic cardiopulmonary bypass with sele ctive cerebral perfusion. He recovered uneventfully. Early recognition and early intervention should be indicated in this otherwise fatal condition.
