LXXX Subglottic Hemangioma as a Cause of Respiratory Obstruction in Infants

Laser treatment of hemangiomas of the larynx and trachea

“…The constriction of the respiratory tract by hemangiomas differs in this way from other obstructive diseases in infancy, such as congenital subglottic stenosis, recurrent paresis, cricoid cartilage hypoplasia, laryngeal cysts, laryngeal valve, and laryngomalacia [3,8,9]. Girls have laryngeal hemangiomas approximately twice as frequently as boys [1,10,11,12]. In 40-60% of the cases there is concomitant involvement of the skin, primarily in the head, throat, and neck region, which was involved in 86% of the cases [5,6,11].…”

“…This should be differentiated from the pedicled adult form found on or above the glottis [11]. A hemangioma can be assumed in a child with the corresponding clinical features and a directly subglottic swelling, even if the typical aspect like that found on the skin is not visible [12]. The larynx and subglottic trachea are by far the most frequently affected areas [1,6,12].…”

The larynx and subglottic trachea are by far the most frequently affected areas [1,6,12]. Angiomas are generally solitary manifestations but multiple localizations in the tracheobronchial system are also possible.…”

“…If a biopsy is necessary, the laser should be used to prevent bleeding. Until the middle of this century, there was still a 50% mortality [12]. Intubation was one of the first measures to eliminate dyspnea [2,15].…”

Hemangiomas infantiles

“…Se manifiestan, en el 80% de los casos, durante el período neonatal, por ronquera, tos, estridor inspiratorio o bifásico y, a veces, cianosis, y pueden progresar rápidamente a la insuficiencia respiratoria. 6,8,10,11,54,58,59 Otra de las localizaciones problemáticas es la zona anogenital, ya que estos HI pueden afectar la diuresis y catarsis por acción mecánica, y suelen ulcerarse.…”
