Considering the patient’s history of RAAF, we diagnosed him with RAAF-induced PVS and performed left superior lobectomy after which hemoptysis did not recur.Conclusions: Unexplained massive hemoptysis should alert clinicians regarding the possibility of RAAF-induced PVS. Balloon angioplasty and stent placement are used to treat PVS;however, their efficacy is controversial considering the high recurrence rates associated with these interventions.展开更多
