■ 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…
