血管瘤是先天性畸形,起源自血管形成组织的中胚层残余。除有气道狭窄者外,在一般解剖部位都可保守处理。儿童声门下血管瘤,对生命威胁最大,Ferguson等报告,死亡率为50%,宜及早治疗。声门下血管瘤的症状有喘鸣、犬吠样咳、体弱、可误诊为克鲁布。约半数患者伴头、颈区皮肤血管瘤。本病虽少见,但正确发病率不详:男女之比为1:2。在病理组织学上大部分属毛细管海绵型;肿物自粘膜下生长,出生后6～12个月间增大,可通过内窥镜确诊,典型的声门 Hemangiomas are congenital malformations that originate from mesoderm remnants of angiogenic tissue. In addition to airway stenosis, the general anatomical site can be treated conservatively. Children with subglottic hemangiomas have the greatest threat to their lives. Ferguson et al. reported that the mortality rate was 50% and should be treated as soon as possible. The symptoms of subglottic hemangiomas are wheezing, canine cough, weakness, and can be misdiagnosed as Klub. About half of the patients had head and neck hemangiomas. Although the disease is rare, the correct incidence is unknown: the ratio between men and women is 1:2. In histopathology, most of them belong to the capillary sponge type; the tumor grows from the submucosal area and increases from 6 to 12 months after birth. It can be diagnosed by endoscopy, typical glottis.
