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

Abstract

Rationale:

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.

Patient concerns:

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.

Diagnoses:

Giant tandem bronchial aneurysms were confirmed using computerized tomographic angiography.

Interventions:

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

Outcomes:

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.

Lessons:

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