Q: Which of these can be used for uterine artery embolization for fibroid uterus?

Polyvinyl alcohol. **Polyvinyl alcohol** - **Polyvinyl alcohol (PVA)** particles are commonly used as embolization material in **uterine artery embolization (UAE)** for fibroids. - These particles create **permanent occlusion** of the small arteries supplying the fibroids, leading to their shrinkage. *Methylene blue* - **Methylene blue** is a dye used for diagnostic purposes (e.g., to identify fistulas) and as an **antiseptic**, not for embolization. - It does not have the physical properties required to achieve arterial occlusion. *Ethacridine lactate* - **Ethacridine lactate** is an **antiseptic** and **abortifacient**, primarily used in second-trimester abortions. - It is not used as an embolization agent for fibroids. *Polyglactin* - **Polyglactin** is a commonly used material for **absorbable sutures** (e.g., Vicryl). - It is designed to be absorbed by the body over time and is not suitable for **permanent arterial occlusion** in embolization procedures.
