[Uremic encephalopathy in regular dialysis treatment: uremic stroke?]
Summary
Uremic encephalopathy caused a neurologic emergency in a dialysis patient. Early identification of arteriovenous fistula recirculation is crucial for treating uremic stroke and improving patient outcomes.
Area of Science:
- Nephrology
- Neurology
Background:
- Uremic encephalopathy is a serious neurologic complication in patients undergoing dialysis.
- Arteriovenous fistula (AVF) dysfunction is a common issue in hemodialysis patients, contributing to morbidity and mortality.
Observation:
- A 59-year-old male on dialysis presented with deep sopor, diagnosed as uremic encephalopathy.
- Initial labs showed elevated creatinine, BUN, and potassium. EEG and ECG were abnormal, but CT brain was unremarkable.
- Hemodialysis initially led to hypokalemia and metabolic acidosis due to AVF recirculation.
Findings:
- The patient's uremic stroke symptoms improved after intensive treatment and placement of a jugular venous hemodialysis catheter.
- The underlying cause was identified as AVF recirculation secondary to high-grade venous stenoses.
- Early detection of dysfunctional AVF is essential for timely intervention to prevent complications like thrombosis.
Implications:
- This case highlights the importance of recognizing vascular access recirculation as a specific cause of neurologic complications in uremic patients.
- Prompt diagnosis and management of AVF dysfunction can lead to regression of uremic stroke and improved patient recovery.
- Strategies to identify and manage AVF issues early are vital for reducing mortality and morbidity in hemodialysis patients.

Hemodialysis II: Procedure and Complications
2.2K
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Hepatic Encephalopathy
53
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Acute Kidney Injury V: Interprofessional Care
527
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

Ischemic Stroke ll: Pathophysiology
54
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

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...
