Platelet Function in a Patient with Thrombasthenia

Platelet function in a patient with thrombasthenia.

PLASMA CLOTTING FACTOR is deficient in most of the “experiments of nature” that have helped to further our understanding of the mechanism of blood coagulation and hemostasis, but in thrombasthenia the defect lies in the platelets which are unable to promote clot retraction. Thrombasthenic patients usually have a mild to moderately severe hemorrhagic diathesis, with a prolonged bleeding time. Th...

Platelet transfusion in a patient affected by Glanzmann's thrombasthenia with antibodies against GPIIb-IIIa.

Patients affected by Glanzmann's thrombasthenia often require blood and platelet transfusions due to bleeding. They may develop antibodies against platelet antigens and become refractory to platelet transfusions. In this study we present our approach to platelet transfusion in a thrombasthenic patient with platelet antibodies directed against gpIIb/IIIa. We found that platelets from two HPA1b/b...

Patients With Glanzmann Thrombasthenia Lacking Platelet Glycoprotein

Background—Platelets have been suggested to play a role in the early development of atherosclerosis. As one test of this hypothesis, we assessed whether patients with Glanzmann thrombasthenia who lack platelet glycoprotein IIb 3 (GPIIb/IIIa) complexes or both IIb 3 and the more ubiquitous v 3 cell membrane complexes are protected from development of atherosclerosis. Methods and Results—Seven pa...

Anaesthetic Management with Thromboelastography in a Patient with Glanzmann Thrombasthenia.

Glanzmann thrombastenia (GT) is a rare disease of an autosomal recessive inheritance characterized with fatal bleeding tendency. The anaesthesiologist should be cognizant of the risk involved and be prepared with necessary measures. In this paper, we present a GT case of a 9-year-old male with hypospadias, which was successfully repaired after platelet transfusions according to the thromboelast...
