Summary
Renal infarction, often mimicking other conditions, requires prompt diagnosis. This case highlights how follow-up imaging is crucial for distinguishing embolic from atherosclerotic causes, optimizing patient outcomes.
Area of Science:
- Nephrology
- Vascular Surgery
- Radiology
Background:
- Renal infarction, a rare condition of interrupted renal blood flow, presents nonspecifically, often delaying diagnosis.
- Early identification is vital to prevent irreversible kidney damage and improve outcomes.
- Imaging is critical for diagnosis and identifying underlying causes like thromboembolism or atherosclerosis.
Purpose of the Study:
- To present a case of renal infarction with a transient, possibly embolic, etiology.
- To emphasize the importance of follow-up imaging in differentiating causes of renal infarction.
Main Methods:
- A case report of a 63-year-old woman with sudden flank pain.
- Initial diagnosis of atherosclerotic renal infarction based on CT angiography showing renal artery stenosis.
- Diagnostic reassessment prompted by follow-up CT angiography revealing resolution of stenosis.
Main Results:
- Initial CT angiography showed severe left renal artery stenosis and infarction.
- Treatment included anticoagulation and antiplatelet therapy.
- Follow-up CT angiography demonstrated complete resolution of stenosis, suggesting an embolic rather than atherosclerotic cause.
Conclusions:
- This case underscores the necessity of follow-up imaging in renal infarction.
- Differentiating embolic from atherosclerotic causes is essential for appropriate management.
- Transient renal artery stenosis may indicate an embolic event.

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

01:22Acute Kidney Injury I: Introduction
72
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
