What is the primary goal of embolization for a left arteriovenous malformation (AVM)?

• A. Reduction of arterial blood flow
• B. Occlusion of the deep arterial feeding vessels
• C. Improvement of neurovascular integrity
• D. Increased cerebral perfusion pressure

Answer: (B)

The primary goal of embolization for a left arteriovenous malformation (AVM) is indeed the occlusion of the deep arterial feeding vessels. This procedure is aimed at decreasing the abnormal blood flow that characterizes an AVM by selectively targeting and blocking the abnormal connections between the arteries and veins. By occluding these feeding vessels, the procedure effectively reduces blood flow to the AVM, which can help prevent bleeding and reduce the risk of hemorrhagic stroke. Occlusion decreases the pressure and volume of blood flowing through the malformation, ultimately assisting in stabilizing the patient and decreasing symptoms related to the AVM. This intervention is crucial, especially in cases where the AVM poses a significant risk of rupture or bleeding. The reduction of arterial blood flow is a secondary effect of the occlusion process, while improvement of neurovascular integrity and increased cerebral perfusion pressure are not primary objectives of the embolization procedure. Improving neurovascular integrity may be a long-term benefit, but it is not the immediate goal of the embolization itself. Increased cerebral perfusion pressure is not a desired outcome in the context of AVMs, as the focus is on managing and mitigating the excessive abnormal blood flow.
