Cervical Insufficiency Treatment with Antai Cervical Ring – Antai Hospital

Antai Cervical Ring

Antai Cervical Ring is a proprietary cervical ring device used in a surgery, secured on the cervical neck, to prevent late miscarriages by enhancing cervical function.

Note: uterus anomalies can result in late miscarriages but cannot be treated with antai cervical ring because it will potentially rupture your womb due to lack of space.

Indication

1. Cervical incompetence 

• Congenital: 
  • The cervical has more muscles than connective tissues (1:1 or 1:2). As a result, there will be a lot of elasticity in the cervix, easy to open during pregnancy.
  • People with congenital cervical incompetency: their cervical muscle ratio is too high. Their cervix muscle to connective tissues is the same as the womb. Womb is largely made of smooth muscles so that it can expand and accommodate a growing baby!!! Womb is originally 5 milliliters, when the baby reaches full term it can accommodate 5000 milliliters. 
• Acquired:
  • Birth trauma (cervix damage after childbirth)

2. Short Cervix (opposite from infantile uterus)

• Congenital: 
  • Ratio of cervix is far smaller than uterus. 
  • Normal cervix: 3.5-4.5 cm 
  • Short cervix: < 3.5 cm
• Acquired:
  • Conization: A procedure done to cut off part of a cervix to prevent cervical cancer.
  • Conization is a surgery that removes the abnormal, precancerous cells from the cervix. 
  • As a result, the cervix will be too short.

Short cervix is under the big umbrella of cervical incompetency/insufficiency.

Diagnosis

1. Prior to Pregnancy：Pelvic Dilation Examination
2. During Pregnacy：B-Scan (check for dilation, length of cervix)

Method

1. Via laparoscopy (transabdominal)
2. Via vagina (transvaginal)
3. Via laparoscopy + vagina (this method is only available at Antai hospital). 

Preventive Surgery

Pre-pregnancy: Laparoscopy 

• Preventive measure against late miscarriage.

Early Pregnancy: Laparoscopy

• Pregnant, but no symptoms of miscarriage yet. Internal orifice not opened yet. Usually, such patients have a history of recurrent miscarriage.
• Through the abdomen because the internal orifice has not opened yet.
• This is also a preventive surgery.

Antai hospital offers guarantee full refund for both situations above (preventive surgeries).

Emergency Surgery

Late Pregnancy: Either laparoscopy or Vaginal

• Threatened miscarriage (will turn inevitable without the surgery).
• Already in the second trimester.
• Internal orifice already opened, but external orifice not opened yet (can be spotted with B-scan).
• During pregnancy, our pelvic floor will be more relaxed because there is a lot of estrogen. This is to prepare for vaginal delivery.
• Hence, by this time, the vagina and pelvic floor are wider and more relaxed, allowing for transvaginal surgery. We can pull out the cervix and secure the Antai cervical ring. 
• However, transvaginal surgery may not be as secure because may not be able to secure on internal orifice.
• It will still be useful, but no full refund guarantee.
• This is high risk, emergency surgery, so no lower price for non-full refund policy. 
• Patients also require labor suppressant (Atosiban) to prevent premature labor and antibiotics Antibiotics to prevent infections because easy to have intrauterine infection (宫内感染).

Acute Surgery 

Inevitable miscarriage: Laparoscopy and Vaginal 

• Will 100 percent miscarry if surgery is not done.

• Internal and external orifice both opened. 
• Need atosiban + Antibiotics + one more (couldn’t catch yi zhi gong sui yao?)
• The fetus already in contact with vaginal bacteria 🡪 extremely easy to have infection.
• Informed Consent to be signed
• There will be a non-zero chance to save the pregnancy.
• We try to convince them to do the acute surgery because some have a very hard time getting pregnant. 
• If they miscarry after an acute surgery, then we provide free pre-pregnancy prevention surgery. 

How acute surgery works:

• Place the antai cervical ring through the vagina.
• Secure the ring through the abdomen (laparoscopy)
• Named Fan Style (creator of the acute surgery)

Double Antai Cervical Ring 

Short Cervix

• Can only be a preventive surgery via laparoscopy, done pre-pregnancy.
• Contractual treatment available. 

Note: Can bed rest and lifting of hips/legs (trendenlenburg position) prevent late miscarriage?

• Cervical insufficiency can lead to miscarriage because of early dilation and the baby is growing day by day.
• Even if you do not move and stay in bed, your baby and amniotic sac will still continue to grow.
• It will still lead to miscarriage once the cervix cannot take the pressure of the growing life anymore. The strength of the seed is limitless. 
• Bed rest is harmful for mother and the child. After months of bed rest, the mother’s muscles will weaken and lead to muscular atrophy.
