■ Primary vascular tumors are exceedingly rare, frequently mimic other oncologic disease processes, and may evolve slowly—leading to delay in diagnosis and treatment. Although most commonly arising from large vessels such…
■ In situ replacement: Low-grade infections without sepsis or invasive infection and those with distal occlusive disease may be best treated with in situ graft replacement. ■ Graft replacement material ■ Graft material…
■ Progressive renal artery stenosis (RAS) or occlusion may predispose to renovascular hypertension (RVH; most common form of secondary hypertension) and ischemic nephropathy.2 Aortic atherosclerosis at the ostia or proximal renal…
■ Acute upper extremity ischemia is less common than in the lower extremity due to the rich preexisting collateral circulation in both the upper arm and forearm. The majority (~50%) of…
IMAGING AND OTHER DIAGNOSTIC STUDIES ■ Current indications for carotid endarterectomy were reviewed in Chapter 3.1–3 ■ In recent years, CTA and MRA have assumed preeminent roles in carotid intervention planning. Improved…
■ Device designs vary with aneurysm extent. For pararenal aneurysms, 70% of patients are adequately treated with two small fenestrations for the renal arteries and a scallop for the superior mesenteric…

IMAGING AND OTHER DIAGNOSTIC STUDIES ■ Transesophageal echocardiography (TEE) may serve as a useful imaging tool, particularly in the setting of acute thoracic aortic pathology. TEE can confirm the presence of…
■ Descending (type B) aortic dissection: Two classifications systems are commonly used to describe the extent of aortic dissections (FIG 2). Stanford type A dissections involve the ascending aorta with or…
