Cerebral hyperperfusion and other consequences of hemodialysis central vein catheters

Area of Science:

• Nephrology
• Neurology
• Vascular Surgery

Background:

• Central venous stenosis is a frequent complication of central venous catheters, intracardiac devices, and instrumentation.
• Most symptomatic patients present with venous hypertension.
• A subset of patients may experience neurological symptoms due to altered intracranial venous circulation.

Purpose of the Study:

• To summarize case report findings on neurological sequelae of central venous stenosis/occlusion.
• To explore the link between central venous stenosis and neurological symptoms in end-stage renal disease patients with arteriovenous access.

Main Methods:

• Review of case reports detailing neurologic symptoms in patients with central venous stenosis/occlusion.
• Analysis of end-stage renal disease patients with functional arteriovenous access.

Main Results:

• Central venous stenosis can lead to abnormal intracranial venous circulation.
• Neurologic symptoms can manifest in patients with central venous stenosis/occlusion.
• End-stage renal disease patients with arteriovenous access are a specific population at risk.

Conclusions:

• Central venous stenosis poses a risk for neurological complications beyond typical venous hypertension.
• Understanding these neurologic sequelae is crucial for managing end-stage renal disease patients with vascular access.
• Further research into the mechanisms and management of these neurologic complications is warranted.
