Uterus and Cervix

Uterus and Cervix

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs of...

In Vitro Fertilization

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Mitral Valve Prolapse III: Nursing Management

Mitral Valve Prolapse III: Nursing Management

The nursing management of Mitral Valve Prolapse, or MVP, centers around patient education, symptom monitoring, and lifestyle modifications.Patient Education on MVP Diagnosis and Heredity: Nurses should provide comprehensive education about MVP, a condition where the mitral valve does not close appropriately during heartbeats. This education often includes the condition's pathophysiology, symptoms, and potential complications, like arrhythmias or mitral regurgitation. Though not fully...

Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Area of Science:

Obstetrics and Gynecology
Maternal-Fetal Medicine
Diagnostic Imaging

Background:

Cervicovaginal fistula is a known complication of mid-trimester pregnancy termination.
It is increasingly recognized as a complication following cervical cerclage procedures.

Observation:

A case of a woman with prior cervical cerclage presenting for a prophylactic Shirodkar cerclage is described.
Transvaginal ultrasonography revealed the amniotic sac protruding through the posterior cervix into the vaginal vault.
Pelvic examination confirmed the prolapse of the amniotic sac through a cervicovaginal fistula.

Findings:

Ultrasound findings of amniotic sac prolapse through a cervicovaginal fistula in a patient with prior cervical cerclage.
This case highlights a rare but significant complication associated with cervical cerclage.

Implications:

Women with a history of cervical cerclage are at risk for developing cervicovaginal fistulas.
Early detection of cervicovaginal fistulas is crucial to prevent potential maternal and fetal morbidity.
This underscores the importance of careful ultrasound evaluation in patients with a history of cervical cerclage.
