Hemodialysis I: Introduction

3.3K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Summary

Multiple spinal dural arteriovenous fistulas (AVFs) are rare, appearing synchronously or metachronously. Diagnosis requires whole-spine angiography if initial treatment fails, to detect additional lesions.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Radiology

Background:

  • Multiple spinal dural arteriovenous fistulas (AVFs) are uncommon vascular malformations.
  • Lesions are typically synchronous and at different spinal levels, but metachronous AVFs also occur.

Observation:

  • This report details two unique cases of multiple spinal AVFs.
  • A review of previously reported cases and theories on the origin of multiple AVFs is included.

Findings:

  • Metachronous AVFs manifest temporally after the treatment of an initial spinal dural arteriovenous fistula.
  • Failure to improve post-treatment necessitates comprehensive spinal angiography.

Implications:

  • Mandatory whole-spine angiography is crucial for complete closure assessment and detection of secondary lesions.
  • Early identification of multiple spinal AVFs can guide appropriate treatment strategies and improve patient outcomes.
