Which of the following is a common treatment approach that involves removing vessels within the nidus of an AVM?

Embolotherapy is a common treatment approach for arteriovenous malformations (AVMs) that involves the intentional occlusion of blood vessels within the nidus of the AVM. This technique helps to reduce blood flow to the abnormal vascular structure, which in turn can help to shrink the AVM, reduce the risk of hemorrhage, and potentially alleviate symptoms associated with the AVM. During the procedure, interventional radiologists use various materials—such as particles, coils, or liquid agents—to block the feeding arteries or draining veins directly.

This method is particularly effective due to the minimally invasive nature of the procedure, allowing for targeted treatment that can be performed through a catheter, thus avoiding the complications associated with open surgical approaches. Embolotherapy is often used as a standalone treatment or as an adjunct to surgical options, providing crucial preoperative reduction of blood flow to facilitate safer surgical resection.

Other treatment options, while relevant in the context of AVMs, do not focus specifically on the direct removal or occlusion of the vessels within the nidus in the same manner. Surgical ligation typically refers to the surgical tying off of blood vessels but may not directly address the nidus as effectively. Laser therapy targets the tissue with light energy but does not
