Cervical diameter after suction termination of pregnancy

Area of Science:

• Reproductive Medicine
• Gynecology

Background:

• Suction termination of pregnancy (TOP) involves cervical dilatation.
• Potential long-term effects of cervical dilatation on cervical os diameter are not fully understood.

Purpose of the Study:

• To assess the impact of vacuum aspiration on internal cervical os diameter.
• To determine the correlation between cervical dilatation during abortion and subsequent cervical os diameter.

Main Methods:

• Measurement of internal cervical os diameter in patient groups.
• Comparison of cervical diameters between women with and without prior vacuum aspiration.
• Correlation analysis between cervical dilatation at operation and follow-up cervical diameter.

Main Results:

• Women with a history of vacuum aspiration showed significantly greater cervical diameters.
• A statistically significant correlation exists between cervical dilatation during the procedure and cervical diameter at six weeks.
• Cervical dilatation ≤10 mm was associated with normal cervical diameter; dilatation >12 mm often resulted in a larger diameter.

Conclusions:

• Vacuum aspiration can lead to increased cervical os diameter.
• The extent of cervical dilatation during termination of pregnancy is a key factor influencing post-procedure cervical diameter.
• It is recommended to limit cervical dilatation to 10 mm during suction termination of pregnancy whenever feasible.
