Which of the following can be used as embolics in the treatment of AVM?

Foam pledgets are used as embolics in the treatment of arteriovenous malformations (AVMs) because they serve as a physical barrier that promotes clot formation and helps occlude blood vessels. The unique composition and structure of foam pledgets allow them to be manipulated into the vascular lesion, where they can effectively block blood flow, thereby diminishing the abnormal connection between the arteries and veins characteristic of AVMs.

Embolization therapy aims to reduce blood supply to the AVM, minimizing the risk of hemorrhage and other complications. The properties of foam as an embolic material, such as its ability to expand and conform to the shape of the vascular structures, make it a desirable choice in interventional procedures targeting AVMs.

In the context of other options, acute care dressings are intended for wound management and do not have properties suitable for embolization. Transfusion products are used to replace lost blood components in patients but have no role in embolizing blood vessels. Local anesthetics are utilized to manage pain during procedures but do not serve any purpose in occluding vascular structures. Overall, foam pledgets provide a strategic approach to managing AVMs through targeted embolization.
