title: Multiple, delayed post-tonsillectomy bleedings in 11-year-old girl as a result of vascular abnormality and anastomosis. Case report.
abstract: Tonsillectomy and adenoidectomy are the most common surgical procedures in pediatric otolaryngology. The incidence of primary hemorrhage after tonsillectomy in children ranges from 0.38 to 6%. The prevalence of secondary bleeding occurs in 0.5%-9.3% cases [1]. Authors present a case of an 11-year-old girl who experienced 6 delayed, massive post-tonsillectomy bleedings as a result of presence of vascular malformation and the activation of collateral circulation as a result of the left ECA ligature.
