Interlocking detachable coil embolization for giant tandem bronchial aneurysms: A case report

Bronchial artery aneurysm (BAA) is a rare disease that can be life-threatening if it ruptures. Tandem connections of multiple aneurysms are even rarer and more challenging to manage.

A 46-year-old woman presented to the hospital with intermittent hemoptysis for a week. A bronchial artery computed tomographic angiography scan revealed 2 BAAs associated with bronchial artery-to-pulmonary artery fistulas in the left lung. Three-dimensional CT reconstruction showed 2 bronchial aneurysms in tandem and 1 aneurysm adjacent to the descending aorta.

Giant tandem bronchial aneurysms were confirmed using computerized tomographic angiography.

Nine interlocking detachable coils and 11 standard pushable coils were introduced into aneurysms for embolization.

There was no episodes of hemoptysis. CT angiography indicated that the coils were closely knit and in their proper position 1 month later; at follow-up, the patient had no adverse effects and no recurrence of hemoptysis.

BAA is a rare disease that can be life-threatening if it ruptures. It should be treated aggressively to determine the presence of symptoms.
