RESUMO
Patients with mild bleeding disorders are under-recognized and frequently present to general physicians. The underlying reasons for bleeding are multifactorial. There is little evidence to guide diagnostic and management decision making in patients with mild bleeding disorders. This article outlines different types of mild bleeding disorders, with a particular focus on bleeding associated with low levels of von Willebrand factor and mild platelet defects. It gives practical, evidence-based advice on the investigation and management of patients with a suspected or known mild bleeding disorder, considering the scenarios of an acute bleed, stable outpatient, peri-surgical management and thrombosis. Patients with a mild bleeding disorder have variable bleeding because of the interplay of genetic and environmental factors. The clinical history remains of utmost importance in their general management. Liaison with a specialist centre, multidisciplinary assessment and a careful judgement of the balance of risk in each individual circumstance is required to safely manage these patients.
