Delayed Diagnosed Subclinic Von Willebrand Disease Case Report

Abstract

The evaluation of the patients who will be operated in terms of preoperative bleeding diathesis is an obligation. This evaluation contains history, physical examination and tests of haemostasis. That are as a routin used among these tests are the number of platelet, PT, aPTT and the values of INR. Despite these assessments, all of the bleeding-clotting disorders have not been able to be determined. Therefore, due to omitted diagnosis of bleeding diathesis, in orthopedic procedures, hemartroz hemarthrosis, intramuscular hematoma, and abandoned bleeding may develop in the postoperative period. These complications are the causes of morbidity and mortality. In one of our cases, who had osteochondroma in his femur diaphysis and also whose preoperative history, examination and mentioned tests were normal, developed recurrent bleeding and hematoma in the operative area in the postoperative period. Von Willebrand disease was determined in the examination which was carried out by being considered bleeding diathesis. As a result, seen at the rate of 1% in community screening and the most common inherited bleeding diathesis, in the cases of Von Willebrand disease's subclinical a good patient history should be taken in order to be able to be early dianosed diagnosed and to be able to be prevent the complications and also the necessary tests for diagnosis should be performed.
