Insights

A retained microcatheter during arteriovenous malformation (AVM) embolization is rare. This report details the second successful surgical retrieval of a retained microcatheter after Onyx embolization for AVM.

Area of Science:

  • Interventional Radiology
  • Neurosurgery
  • Vascular Surgery

Background:

  • Arteriovenous malformations (AVMs) are complex vascular anomalies.
  • Embolization is a primary treatment for AVMs.
  • Microcatheter use in AVM embolization carries risks, including retention.

Observation:

  • Retained microcatheter is a rare complication during AVM embolization.
  • The incidence of retained catheters has decreased with the use of Onyx.
  • Surgical retrieval of retained microcatheters is exceptionally uncommon.

Findings:

  • This paper documents the second reported case of successful surgical retrieval of a retained microcatheter.
  • The microcatheter was retained following Onyx embolization of an AVM.
  • The retrieval procedure was successful in this case.

Implications:

  • This case highlights a rare but significant complication in AVM treatment.
  • It underscores the importance of vigilance and potential need for surgical intervention.
  • Successful retrieval offers valuable insights for managing similar rare complications.

Hemodialysis I: Introduction

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...

Cardiac Catheterization IV: Nursing Management

Nursing responsibilities before cardiac catheterization include:Assess for allergies and establish baseline health status.Before cardiac catheterization, assess the patient for allergies to contrast dye. Perform a comprehensive baseline assessment, including vital signs, heart and breath sounds, and a neurovascular assessment of the extremities, noting distal pulses, skin color, and temperature. Instruct the patient to fast for 8-12 hours before the procedure. Evaluate baseline laboratory...

Venous Thrombosis III: Interprofessional Care

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...
