Haemostatic disorders in habitual nose-bleeders.

Ninety-one habitual nose-bleeders were screened for haemostatic disorders. 46 screening results in 38 nose-bleeders were outside the normal range. After extended investigation, it was found that 25 (27 per cent) habitual nose-bleeders had haemostatic disorders, all except one in the primary haemostasis. The disorders found could be classified as mild bleeding disorders (MBD) and compared to the estimated frequency of MBD in the population there was an increased incidence of haemostatic disorders in the habitual nose-bleeders. Abnormal vessels in the nasal mucosa were present in 85 per cent of the investigated nose-bleeders, equally distributed between nose-bleeders with and without haemostatic disorders. This indicates that abnormal vessels and haemostatic disorders in habitual nose-bleeders, it is possible to detect previously unknown but clinically important disorders.
