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 .
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
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 ...
Generally, diseases outlined within the ICD-10 codes N00-N19, N20.0 within Chapter XIV: Diseases of the genitourinary system should be included in this category. Wikimedia Commons has media related to Kidney diseases .
[8] [9] [10] There are two main causes of renovascular hypertension: renal artery stenosis and fibromuscular dysplasia. [citation needed] The normal physiological response to low blood pressure in the renal arteries is to increase cardiac output (CO) to maintain the pressure needed for glomerular filtration. Here, however, increased CO cannot ...
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]
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 .
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.
