Von Willebrand Disease type 2 in pregnancy - A critical clinical association.

Von Willebrand disease (vWD) is the most common inherited bleeding disorder. Its association with pregnancy is infrequent. Here we report three cases of vWD associated with pregnancy. The clinical features of this combination are very suggestive. However, difficulties are still encountered during the diagnosis process. The first case was diagnosed for the first time during the patient's second pregnancy despite several episodes of vaginal bleeding and suggestive clinical symptomatology. The second case was diagnosed during childhood and the patient was properly managed during this pregnancy. The third case was diagnosed at a pre-anesthesia consult, at 36 weeks gestation, before performing a cesarean section on request, despite a clinical suggestive symptomatology. All of the cases received prophylactic treatment with Haemate P® (CSL Behring, Marburg, Germay) 24hours before birth. No serious bleeding episodes were noticed during delivery or postpartum period. Two healthy babies were delivered from the cases Nos. 2 and 3. It is acknowledged that vaginal bleeding is common during first trimester of pregnancy. However, this study indicates that repeated bleeding episodes corroborated with a clinical suggestive symptomatology (epistaxis, heavy menstrual period, and easy bruising after minor trauma) should orient the diagnosis to vWD.
