UNLABELLED: In patients with isolated prolonged in vitro bleeding time there is no standardised treatment concept. With this study we characterized the extent of bleeding symptoms.
PATIENTS, METHODS: All diagnoses known to cause prolonged in vitro bleeding time (PFA-100) (epinephrine-cartridge >160 s, ADP-cartridge > 120 s) have been excluded, such as platelet function disorders, effects of medications, nutrition or von Willebrand disease. 75 patients (77%, n = 58 women; 23%, n = 17 men, median age 46 (16-81) years were included. All bleeding symptoms have been stored in a databank with help of a comprehensive questionnaire.
RESULTS: 78% (n = 54) of all patients reported of having had an operation, 69.8% (n = 37) of them described postoperative bleedings (p = 0.0373). 13.5% (n = 5) of the 54 could remember having been randomly treated by the administration of a transfusion and only 2.7% (n = 1) were treated by substitution of von Willebrand factor. 71% (n = 51) patients indicated haematoma (p = 0.8116). About 33.8% (n = 24) patients had gum bleeding and 40.8% (n = 29, p = 0.7808) patients reported bleeding after the dentist. 41.4% (n = 29) patients suffered under frequent epistaxis (p = 0.0212). There was no correlation between prolonged epinephrine bleeding time to VWF:Ag (rho = 0.16) nor to VWF:RCo (rho = 0.12) nor between prolonged epinephrine and ADP bleeding time (rho = 0.01) nor to ROTEM® analysis.
CONCLUSION: Patients with isolated prolonged PFA are mainly women and can be affected by all kinds of bleedings while haematoma is the main symptom. VWD might not be causal.
