Fístula aortobroncopulmonar em pós-operatório tardio de coarctação da aorta

Delayed diagnosis of hemoptysis in the case of prior aortic coarctation repair: A case report of aortobronchial fistula

“…Once formed, the continuous pressure of blood against the weakened vascular wall leads to damage of the aorta and subsequent lung parenchyma - usually of the left lung - resulting in the formation of a communication between the two structures. Furthermore, the foreign material can become attached to the lung tissue and cause inflammation [2] .…”

“…This imaging can reveal, in addition to the aneurysm itself, periaortic hematoma, mural thrombus and contrast extravasation to the lung parenchyma. When ABF is suspected, bronchoscopy must be used with caution, particularly when there is abundant hemoptysis; the scope may cause mobilization of thrombi in the fistula, which may lead to massive hemorrhage [2] .…”
