Summary
Intrauterine arteriovenous malformations can cause persistent metrorrhagia, particularly after pregnancy complications. Embolization is a rapid, effective treatment, allowing future pregnancies.
Area of Science:
- Gynecology
- Vascular Malformations
- Reproductive Medicine
Background:
- Persistent metrorrhagia can stem from intrauterine arteriovenous malformations (AVMs).
- Risk factors include a history of miscarriages, cornual pregnancy, molar pregnancy, or gestational trophoblastic diseases.
Observation:
- This study presents four cases of intrauterine AVMs.
- Diagnosis relies initially on Doppler ultrasonography.
- Angiography confirms the diagnosis.
Findings:
- Embolization is the primary treatment, often performed concurrently with angiography.
- This interventional radiology technique is swift and definitive.
Implications:
- Embolization preserves fertility, enabling subsequent pregnancies.
- Post-treatment ultrasound follow-up is recommended to monitor AVM involution.

01:14Fetal 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...

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
