Carotid pulsatility indices in surgical menopause

Area of Science:

• Vascular Medicine
• Endocrinology
• Surgical Menopause

Background:

• Limited research exists on hormone replacement therapy (HRT) effects in surgically menopausal women.
• Previous studies focused on naturally menopausal women regarding HRT and vascular health.

Purpose of the Study:

• To evaluate the pulsatility indices (PI) of internal carotid arteries in surgically menopausal women.
• To compare PI in women undergoing HRT versus those not receiving HRT post-surgery.

Main Methods:

• Color Doppler ultrasound was used to measure internal carotid artery PIs.
• Two groups were compared: untreated surgical menopausal women (n=38) and HRT-treated surgical menopausal women (n=42).
• Pre- and post-operative PI measurements were analyzed.

Main Results:

• A statistically significant increase in carotid artery PIs was observed in the untreated group compared to the HRT group post-operatively (p < 0.001).
• The untreated group showed significant pre- to post-operative PI increases (p < 0.001), while the HRT group did not (p > 0.200).
• Pre-operatively, no significant PI difference existed between groups, but a significant difference emerged post-operatively (p < 0.05).

Conclusions:

• Hormone replacement therapy demonstrates beneficial effects on internal carotid artery pulsatility indices in surgically menopausal women.
• Findings align with previous research on HRT's vascular benefits in naturally menopausal women.
• HRT may play a role in maintaining vascular health in women experiencing surgical menopause.
