Endovascular embolization for primary racemose hemangioma of the bronchial artery supplied by multiple systemic arteries: A rare case report

RHBA with multi-source NBSAs involvement is rare. During interventional procedure, it must carefully consider the influence of diverse arterial blood flow on distal ectopic embolization, and omission of any feeding NBSAs can precipitate RHBA recurrence. In this case, carefully super-selective catheterization combined with microcoils deployment offered a safe, effective therapeutic option.
