Abstract
Background: We present the case study of a 28-year-old pregnant woman with antithrombin deficiency who was treated with low-molecular-weight heparin (LMWH). Methods: Due to severe homozygous type II antithrombin heparin binding site (HBS) deficiency, the thrombin generation (TG) was monitored in this woman via the Thrombin Generation Assay (TGA).
We used Siemens diagnostic kits Berichrom(R) Antithrombin III (IIa) and INNOVANCE(R) Antithrombin (Xa) to determine antithrombin activity. We used a chromogenic method for determination of factor Xa (FXa) inhibition.
Results: There were no thrombotic complications during the whole pregnancy of the observed woman. Antithrombin was administered before and after delivery, which was significantly reflected in the decrease in thrombin generation.
Conclusions: Consistent monitoring of thrombin generation with LMWH anticoagulant therapy administration during pregnancy together with antithrombin administration before and after delivery can improve the overall condition of pregnant women and the quality of their care.
