Zastosowanie laseroterapii i rVIIa w leczeniu krwawienia do tkanek miękkich w trombastenii Glanzmanna

Abstract

Glanzmann’s thrombasthenia (GT) is a rare thrombocytopathy. It is an autosomal recessive disorder. This disease is caused by the quantitative or qualitative defect of the αIIbβ3 membrane integrin, which is the receptor binding the adhesion proteins to the platelet surface in the initial stage of the coagulation process. Abnormal platelet aggregation associated with the αIIbβ3 mutation is the cause of serious and challenging bleeding. The first-line treatment for severe bleeding is transfusion of platelet concentrate or recombinant factor VIIa (rFVIIa) in case of refractoriness to transfusion. The primary objective of this study was to describe clinical effects observed in laser treatment of muscle bleeding in patients with coagulation disorders. We present the case of a 13-year-old boy with TG who was admitted to the hospital with quadriceps muscle hematoma after falling from the bicycle. Due to the lack of response to a platlet concentrate we used rFVIIa with a good effect. Due to the presence of a large painful muscle hematoma, we started laser therapy. Significant pain reduction and rapid hematoma regression were observed.
