[Accentuated and irregular post-maximal deflection in thromboelastographic tracings: occurrence in various

|February 28, 1985
Summary
Irregular thromboelastography (TEG) patterns, often linked to technique errors, are rare in healthy individuals. These specific TEG findings significantly appear in patients with diabetes mellitus, obesity, or hypertension, suggesting potential hemostatic alterations.
Area of Science:
- Hematology
- Clinical Pathology
- Medical Diagnostics
Context:
- Thromboelastography (TEG) is a global screening test for hemostasis evaluation.
- The interpretation of increased and irregular post-maximal deflection in TEG traces is variable.
- These patterns have been previously attributed to fibrinolysis, clot retraction, or technical errors.
Purpose:
- To evaluate the incidence of increased and irregular post-maximal TEG deflection patterns.
- To determine the occurrence of these patterns in healthy subjects versus patients with various diseases.
- To investigate the potential diagnostic significance of these specific TEG findings.
Summary:
- A retrospective review of 1701 TEG traces was conducted over five years.
- Irregular post-maximal deflection patterns were largely absent in healthy subjects.
- A statistically significant incidence of these patterns was observed in patients with diabetes mellitus, obesity, and systemic hypertension.
Impact:
- The findings suggest that irregular post-maximal TEG deflection is not solely a technical artifact.
- This pattern may serve as a valuable indicator of specific hemostatic alterations.
- Further research is warranted to elucidate the clinical implications of these TEG findings.
