Renal infarction is a medical condition caused by an abrupt disruption of the renal blood flow in either one of the segmental branches or the major ipsilateral renal artery. [3] Patients who have experienced an acute renal infarction usually report sudden onset flank pain , which is often accompanied by fever , nausea , and vomiting .
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney , resulting in renovascular hypertension – a secondary type of high blood pressure .
This leads to a build-up of plaques and they can be deposited in the renal arteries causing stenosis and ischemic kidney disease. [citation needed] In this situation, the kidney supplied blood by the narrowed renal artery suffers from inadequate blood flow, which in turn causes the size of the kidneys to decrease. Other consequences include ...
The prognosis of individuals with renovascular hypertension is not easy to determine. Those with atherosclerotic renal artery disease have a high risk of mortality, furthermore, those who also have renal dysfunction have a higher mortality risk. However, the majority of renovascular diseases can be improved with surgery. [4]
Applying spectral Doppler to the renal artery and selected interlobular arteries, peak systolic velocities, resistive index, and acceleration curves can be estimated (Figure 4) (e.g., peak systolic velocity of the renal artery above 180 cm/s is a predictor of renal artery stenosis of more than 60%, and a resistive index, which is a calculated ...
The captopril challenge test (CCT) is a non-invasive medical test that measures the change in renin plasma-levels in response to administration of captopril, an angiotensin converting enzyme inhibitor. It is used to assist in the diagnosis of renal artery stenosis.
Cardiorenal syndrome (CRS) is an umbrella term used in the medical field that defines disorders of the heart and kidneys whereby "acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other". [1] When one of these organs fails, the other may subsequently fail. [2]
Atherosclerotic obstruction of the renal artery can be treated with angioplasty with or without stenting of the renal artery. [10] There is a weak recommendation for renal artery angioplasty in patients with renal artery stenosis and flash edema or congestive heart failure. [10]
