Ischemic nephropathy in an elderly patient

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 2 2008
Satoshi Hoshide
Congestive heart failure often occurs in patients with bilateral renal artery stenosis. Recently, Jacobson and Breyer, and Jacobson introduced the term "ischemic nephropathy", which implies critical bilateral involvement or global ischemia. Ischemic nephropathy is not only a cause of hypertension but also an important cause of end-stage renal disease. However, the aging kidney often show that the renal artery does not demonstrate stenosis of the main trunks, but stenosis of an atherosclerotic branch. We present a case of multiple atherosclerotic peripheral renal arteries, which might have caused ischemic nephropathy in an elderly hypertensive patient with advanced atherosclerosis. [source]

Diagnosis and Management of Renovascular Disease and Renovascular Hypertension

JOURNAL OF CLINICAL HYPERTENSION, Issue 5 2007
Michael J. Bloch MD
Renovascular disease is a common but complex disorder, the most common causes of which are fibromuscular dysplasia and atherosclerosis. Clinically, it can present as asymptomatic renal artery stenosis, renovascular hypertension, or ischemic nephropathy. Assessing the clinical index of suspicion remains essential in determining an appropriate diagnostic strategy. For diagnosis in patients with suspected fibromuscular disease, it may be reasonable to proceed directly to renal angiography; however, for most patients with suspected atherosclerotic disease, there are a number of noninvasive tests available that can aid in decision making. The choice of the most appropriate initial test should be based on patient characteristics, clinical presentation, and local expertise. Treatment options include medical, surgical, or percutaneous approaches. Generally, in patients with fibromuscular disease, percutaneous intervention provides durable improvement or cure of hypertension. In patients with atherosclerotic disease, the data are less consistent, and there does appear to be a group of patients who will respond well to medical management alone. As technology advances, the diagnostic and treatment paradigms will continue to evolve. [source]
