European guidelines classify a pre-existing decreased kidney function to be a risk factor of contrast-induced nephropathy in the following cases: [5]. Estimated glomerular filtration rate (eGFR) < 45 ml/min/1.73 m 2 of body surface area before intra-arterial administration with first-pass renal exposure (not passing lungs or peripheral circulation before kidneys), or in the intensive care unit
In 2006, the link between NSF and gadolinium-based MRI contrast agents was made. [ 4 ] [ 23 ] [ 24 ] As a result, restrictions on use of GBCAs in patients with an estimated glomerular filtration rate (a measure of kidney function ) under 60 and especially under 30 mL/min/1.73 m 2 have been recommended and NSF is now considered rare.
Patients with severely deteriorated kidney function are more at risk for NSF, with dialysis patients being more at risk than patients with mild chronic kidney disease. [ 21 ] [ 22 ] NSF can be caused by linear and macrocyclic [ 23 ] [ 24 ] (macrocyclic ionic compounds have been found the least likely to release the Gd 3+ ), [ 25 ] [ 17 ...
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 category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. 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.
The flow of contrast (up from the bladder to the kidney) is opposite the usual outbound flow of urine, hence the retrograde ("moving backwards") name. A retrograde pyelogram may be performed to find the cause of blood in the urine , or to locate the position of a stone or narrowing, tumour or clot, as an adjunct during the placement of ureteral ...
However, recent studies have shown that the risk of kidney injury caused by contrast agent in patients with no history of kidney problems occurs extremely infrequently. [ 12 ] [ 13 ] [ 14 ] The use of CTA in people with kidney failure , kidney disease or long-standing severe diabetes should be weighed carefully as the use of IV iodine contrast ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
