[Obstetric and gynecological intervention in women with Bernard-Soulier syndrome: report of two cases].

Introduction Bernard-Soulier syndrome (BSS) is a rare inherited bleeding disorder characterized by giant platelets thrombocytopenia, prolonged bleeding time, frequent hemorrhages with considerable morbidity. Data on the outcome of pregnancy and gynecological intervention in BSS are rare and there are no general therapeutic recommendations. CASES OUTLINE: We report two cases of BSS. In the first case a 29-year-old patient with BSS was admitted in 8 weeks of gestation. The diagnosis of BSS was made on the basis of prolonged bleeding time, giant-platelets thrombocytopenia, and absent ristocetin-induced platelet aggregation. In 38 week of gestation Cesarean section, with platelets transfusion preparation, was performed. Obstetric intervention passed without complication. Postoperative course was complicated with a three-week vaginal bleeding resistant to platelet transfusion. Neonate platelet count was normal. Our second case was a 28-year-old patient with BSS, hospitalized for ovarial tumor surgery. The patient was prepared for the intervention with platelets transfusion. The surgery was uncomplicated, but on the second postoperative day a massive vaginal bleeding, resistant to the platelet transfusion, developed. Bleeding control was achieved with activated recombinant factor VII. Twelve hours the patient developed later hypertensive crisis with epileptic seizure due to subarachnoid hemorrhage. Therapy was continued with platelet transfusion, antihypertensive and antiedema drugs. PH examination of tumor tissue showed hemorrhagic ovarial cyst. CONCLUSION: Obstretic and gynecological intervention in women with BSS may be associated with a life-threatening bleeding thus requiring a multidisciplinary approach with adequate preparation. Because of the limited data in the literature, it is not possible to provide firm management recommendations and each case should be managed individually.

Perioperative management of tonsilloadenoidectomy and circumcision of a patient with Bernard-Soulier syndrome: case report.

Bernard-Soulier syndrome is an autosomal recessive coagulopathy characterized by thrombocytopenia, prolonged bleeding time and large platelets. Because of the rarity of this disease, standard perioperative treatment protocols have not been developed and there are not enough available data for the management of surgical procedures. In this case, we successfully performed adenoidectomy and tonsillectomy and circumcision surgery concurrently under the preventive and intermittent transfusion of platelets. During hospitalization, no intraoperative or postoperative bleeding complications occurred.

The use of recombinant factor VIIa in children with inherited platelet function disorders.

Inherited deficiencies of platelet surface glycoproteins such as Glanzmann's thrombasthenia (GT) or Bernard-Soulier syndrome (BSS) can lead to a severe bleeding diathesis. In the past, bleeding episodes in these patients have often required platelet transfusion to secure haemostasis but recently a number of patient reports have suggested that recombinant factor VIIa (rVIIa) may also be effective. We have used rVIIa on 33 occasions in seven children with inherited platelet function disorders over a 2-year period: five had GT, one had BSS and one had storage pool disease with a severe phenotype. Bleeding ceased with rVIIa alone in 10 of 28 acute bleeding episodes, but recurred in two of these. The two features that predicted response to rVIIa were the severity of the bleeding and the delay from the onset of bleeding to treatment. Five episodes of planned surgical intervention were treated successfully with rVIIa. Eighteen out of the 28 acute episodes and none of the planned surgical episodes required blood product support. We have found variable efficacy of rVIIa for acute bleeding episodes in this small series of children with inherited platelet function defects but larger studies are warranted, particularly as rVIIa is a relatively low-risk treatment approach for these disorders.
