Clinical characteristics and postoperative outcomes of systemic artery-to-pulmonary vessel fistula in hemoptysis patients.

Objectives: To investigate the clinical characteristics and outcomes on the success of bronchial arterial embolization (BAE) in patients with and without systemic artery-to-pulmonary vessel fistula (SA-PF) and to evaluate the feasibility of CTA in the assessment of SA-PF.

Methods: We retrospectively enrolled 420 consecutive patients that underwent BAE for hemoptysis control in our hospital from September 2011 to May 2019. The clinical characteristics, preprocedural CTA findings, BAE procedural findings, and follow-up outcomes were collected.
