Techniques for treating visceral aneurysms are based on location and anatomic region and also on whether an aneurysm is a true aneurysm or a pseudoaneurysm. Visceral artery aneurysms typically require treatment if they are greater than 2 cm. Aneurysms that are favorable for endovascular therapy include saccular aneurysms preferably with a narrow neck and/or aneurysms that have good collateral blood flow to the target organ. Endovascular techniques for treating arteriovenous malformations (AVMs) are multifaceted and require appropriate identification of the AVM using multiple imaging modalities in addition to angiography. AVMs can be defined as slow flow, intermediate flow, and high flow.
