Clinical effect of endovascular embolization in treatment of hemoptysis of systemic arterial origin in children / 中国当代儿科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical effect of endovascular embolization (EVE) in the treatment of hemoptysis of systemic arterial origin in children.</p><p><b>METHODS</b>A total of 20 children with hemoptysis of systemic arterial origin who underwent EVE from January 2016 to November 2017 were enrolled. The method for embolization was analyzed and the clinical outcome was evaluated.</p><p><b>RESULTS</b>Offending vessels were bronchial artery (BA) in 14 children, non-bronchial systemic artery (NBSA) in 1 child, and BA and NBSA in 5 children. Of all the children, 13 underwent EVE with peripheral embolization agents and 7 underwent EVE with mechanical coils. A total of 41 offending vessels were embolized (34 BAs and 7 NBSAs) and all the children achieved immediate arrest of hemoptysis. Two children experienced recurrence within 6 months after EVE and 2 experienced recurrence with 6-24 months after EVE. The peripheral embolization agent group had a lower overall recurrence rate than the mechanical coil group [8%(1/13) vs 43%(3/7); P=0.10]. One child experienced intracranial ectopic embolism after surgery and had good quality of life during 20 months of follow-up after treatment. No other complications were observed.</p><p><b>CONCLUSIONS</b>EVE is a safe and effective method for the treatment of hemoptysis of systemic arterial origin in children and thus holds promise for clinical application.</p>
