Doppler ultrasonography was performed to measure arterial parameters, including middle cerebral artery (MCA), umbilical artery (UA), and uterine artery (UtA), and venous parameters, including pulmonary vein (PV), inferior vena cava (IVC), and ductus venosus (DV). Composite adverse perinatal outcomes (CAPO) were analyzed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      MCA S\/D ratio and pulsatility index (PI) were significantly elevated in both GDM groups (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001), while UA and UtA parameters showed no significant differences between the groups. Venous Doppler parameters, including PV, IVC, and DV, did not correlate significantly with CAPO. The hepatic vein S\/D ratio demonstrated a borderline significant increase in the idiopathic polyhydramnios group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.041). Although certain adverse neonatal outcomes, such as transient tachypnea of the newborn (TTN) and neonatal hypoglycemia, were more frequently observed in the GDM groups, no significant association was found between Doppler parameters and CAPO.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Venous Doppler measurements demonstrated minimal utility in forecasting unfavorable neonatal outcomes, whereas MCA Doppler parameters showed modest discriminatory ability and may reflect altered fetal hemodynamics in GDM pregnancies; however, their clinical utility remains limited.
