Von Willebrand disease as cause of unanticipated bleeding following adeno-tonsillectomy.
Von Willebrand disease (vWD) is a frequent autosomal bleeding disorder. We report two unsuspected patients over 6 years of age with this disease operated by tonsillectomy and adenoidectomy (T&A) at our Department. Preoperative hematologic work-up (with activated partial thromboplastic time, prothrombin time, fibrinogen, and platelet count) was normal. Both patients had undergone previous adenoidectomy without complications. In both cases, profuse bleeding was noted in the immediate postoperative period. The therapeutic measures in these situations are discussed and a review of the current literature concerning preoperative hematologic evaluation of T&A is included.
