Glanzmann's thrombasthenia. Report of two oral surgical cases using a new microfibrillar collagen preparation and EACA for hemostasis.
Glanzmann's thromboasthenia is a rare congenital platelet disorder characterized by a prolonged bleeding time, a qualitative platelet defect, and severe hemorrhagic episodes. Patients with this disorder have been managed by administration of blood and blood components (most recently, platelet-rich plasma and platelet concentrates) to control hemorrhage resulting from trauma or surgical procedures. The two case reports presented here illustrate the use of a local hemostatic agent (microfibrillar bovine collagen, Avitene) and a systemic fibrinolytic inhibitor (epsilon aminocaproic acid, Amicar) to control postoperative hemorrhage secondary to elective extraction of teeth. The clinical results demonstrate excellent postoperative hemostasis and support recent in vitro observation of platelet adherence to the collagen preparation. This provides an alternate therapeutic modality in the management of patients with Glanzmann's disease and possibly other disorders of platelet function.
