Acute Kidney Injury I: Introduction01:22

Acute Kidney Injury I: Introduction

1.1K
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...

Imaging Studies VII: Vascular Imaging

448
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...

Acute Kidney Injury II: Pathophysiology

1.7K
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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

629
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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

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...

Venous Thrombosis III: Interprofessional Care

455
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Area of Science:

  • Nephrology
  • Vascular Medicine
  • Radiology

Background:

  • Anticoagulant therapy is crucial for managing rheumatic valvular disease and atrial fibrillation.
  • Renal infarction is a potential complication in patients with embolic risk factors.

Observation:

  • A 65-year-old female presented with acute right lower abdominal pain.
  • Physical examination showed no significant abdominal or flank tenderness.
  • The patient had a history of rheumatic valvular disease and atrial fibrillation, managed with anticoagulants.

Findings:

  • Computed tomography angiography (CTA) confirmed right thrombo-embolic renal infarction.
  • The diagnosis highlights the kidney as a potential site for embolic events.

Implications:

  • This case underscores the importance of considering thrombo-embolic events in the differential diagnosis of abdominal pain, even without typical flank tenderness.
  • Prompt diagnosis via CTA is essential for appropriate management and to prevent further complications.
  • Awareness of renal infarction in patients on anticoagulation is critical for early detection and intervention.
