Platelet indices like mean platelet volume (MPV) and platelet to lymphocyte ratio (PLR) were lower, while platelet distribution width (PDW) was higher in patients with placental abruption (PA). These findings suggest potential diagnostic value for these markers in early PA assessment.
Area of Science:
- Obstetrics and Gynecology
- Hematology
Background:
- Placental abruption (PA) is a critical obstetric emergency.
- Early diagnosis of PA is crucial for effective management and improved outcomes.
Purpose of the Study:
- To investigate the utility of platelet indices in the early diagnosis of placental abruption (PA).
- To assess if specific platelet parameters can aid in differentiating PA from other conditions.
Main Methods:
- A case-control study involving 62 pregnant women with PA and 130 controls.
- Analysis of platelet indices (MPV, PDW), biochemical, and coagulation parameters before cesarean section.
- Recording of maternal and neonatal outcomes.
Main Results:
- No significant differences in hemoglobin, hematocrit, or white blood cell count between groups.
- Significantly lower platelet count, mean platelet volume (MPV), and platelet to lymphocyte ratio (PLR) in PA patients.
- Significantly higher platelet distribution width (PDW) in PA patients compared to controls.
Conclusions:
- Mean platelet volume (MPV) and platelet to lymphocyte ratio (PLR) were found to be lower in patients with placental abruption.
- Platelet distribution width (PDW) was observed to be higher in placental abruption patients.
- These platelet indices may serve as valuable biomarkers for the early assessment and diagnosis of placental abruption.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
