Objective To investigate the safety and efficacy of embolization of inferior phrenic artery as nonbronchial systemic artery(NBSA) for hemoptysis.Methods Imaging and clinical data of 1 1 patients with inferior phrenic artery as NBSA were analyzed retrospectively, and complications and hemoptysis recurrence rate were recorded.Results Seven patients underwent enhanced CT examination and 4 patients underwent plain CT examination before embolization.Six of those patients who underwent enhanced CT examination were found abnormal arteries,and were confirmed as NBSA by angiography.The other 5 patients were found unmatch of lesion distribution and bronchial arteries during procedure,and inferior phrenic artery as NBSA were found by expanding angiography.All procedure were successfully performed,3 cases occurred hiccup and need not treatment.No serious complications occurred,such as incontinence and paraplegia.During (1 8.7 ± 1 3.8)months follow-up,only 1 patient recurrence of hemoptysis,and successful after conservative treatment,and the other 10 patients had no recurrence of hemoptysis.Conclusion The inferior phrenic artery as NBSA can induce hemoptysis.It is safe to embolization of the inferior phrenic artery,which can reduce the recurrent rate of hemoptysis.
