Summary
Acute renal infarction, a rare condition, can lead to severe kidney disease. This case highlights cardioemboli from atrial fibrillation as a cause of renal infarction in a young adult.
Area of Science:
- Nephrology
- Cardiology
- Vascular Medicine
Background:
- Acute renal infarction is an uncommon cause of kidney damage.
- It can result in serious complications like chronic kidney disease and renovascular hypertension.
- Prompt diagnosis is crucial for patient outcomes.
Purpose of the Study:
- To report a case of acute renal infarction in a young adult.
- To identify the underlying cause of cardioembolism leading to renal infarction.
- To emphasize the importance of considering cardiac sources in young patients with unexplained flank pain.
Main Methods:
- Case presentation of a 30-year-old male with sudden right flank pain.
- Initial diagnostic workup for suspected pyelonephritis.
- Subsequent investigations revealing acute renal infarction secondary to atrial fibrillation.
Main Results:
- The patient presented with symptoms mimicking pyelonephritis.
- Imaging confirmed acute renal infarction.
- Atrial fibrillation was identified as the source of cardioemboli.
Conclusions:
- Atrial fibrillation can be a cause of acute renal infarction, even in young, otherwise healthy individuals.
- This case underscores the need for comprehensive cardiac evaluation in patients with renal infarction.
- Early recognition and management of atrial fibrillation are vital to prevent recurrent embolic events and preserve renal function.

01:28Cardiac Catheterization I: Pre-Procedure Overview
146
Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

01:29Pulmonary Embolism I: Introduction
45
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

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...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

01:22Acute Kidney Injury I: Introduction
68
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...

01:30Continuous Renal Replacement Therapy
121
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...
