Massive blood loss during tonsillectomy in a child with congenital venous malformation.
Tonsillectomy and adenoidectomy have become frequently performed outpatient procedures and are generally considered to have a low morbidity profile. Postoperative haemorrhage remains a rare but important complication, while intraoperative uncontrollable bleeding is extremely uncommon. A child with congenital vascular malformation of the lip and oropharynx undergoing tonsillectomy experienced massive blood loss, subsequent resuscitation and significant perioperative morbidity including a prolonged intensive care unit stay. Preoperative/preanaesthetic nasopharyngoscopic exam and magnetic resonance imaging did not reveal vascular prominence of the tonsils. Preoperative consideration of angiography or magnetic resonance angiography may be prudent to avoid this potentially fatal complication.
