Y1 - 2024 N1 - T2 - Vascular and Endovascular Surgery: Clinical Diagnosis and Management AB - Peripheral aneurysms can be broadly categorized, based on location, into upper and lower extremity aneurysms. In any artery, the Society for Vascular Surgery clinical practice guidelines defines an aneurysm as a focal dilation 1.5 times the normal diameter of the disease-free proximal adjacent segment.1 True aneurysms consist of the outpouching of all three layers of the vessel wall including tunica intima, media, and adventitia. False aneurysms (pseudoaneurysms), on the other hand, include dilation of one or two layers of the vessel wall (Figure 30-1a-b). The most common false aneurysms will be discussed separately after the corresponding artery.
