Bleeding is a rare but fatal complication after radiotherapy for nasoparyngeal carcinoma(NPC).In this article,we report an NPC case treated with radiotherapy complicated with bleeding of the common carotid artery(CCA).A 44-year-old man with NPC was treated with external radiotherapy 19 years ago,and a second course of treatment to the same field was administrated because of local nasoparyngeal recurrence 4 years ago.The patient was admitted to our hospital for massive bleeding.Conservative therapy including routine medication,blood transfusion and local compression showed almost no effect.Emergency carotid angiography revealed bleeding from the left CCA,and a self-expanding covered stent was deployed through percutaneous transluminal femoral approach.After the placement of the co-vered stent,angiography showed the bleeding was successfully controlled.So self-expanding covered stenting may be a safe,effective and minimal-invasive option for bleeding of the carotid artery.Long-term follow-up is required for further evaluation.Abstract:SUMM ARY B leed ing is a rare but fatal complication after rad iotherapy for nasoparyngeal carcinoma(NPC).In this article,we report an NPC case treated with rad iotherapy complicated with bleed ing of the common carotid artery(CCA).A 44-year-old man with NPC was treated with external rad iotherapy 19 years ago,and a second course of treatment to the same field was adm inistrated because of local nasopa-ryngeal recurrence 4 years ago.The patientwas adm itted to our hospital formassive bleed ing.Conserva-tive therapy includ ing routine med ication,blood transfusion and local compression showed almost no effect.Emergency carotid angiography revealed bleed ing from the leftCCA,and a self-expand ing covered stentwas deployed through percutaneous translum inal femoral approach.After the placement of the co-vered stent,angiography showed the bleed ing was successfully controlled.So self-expand ing covered stenting may be a safe,effective and m inimal-invasive option for bleed ing of the carotid artery.Long-term follow-up is required for further evaluation.
