Abstract

Insights

Complications during endovascular treatment of dural arteriovenous fistulae (dural AVFs) are uncommon, occurring at a 9% rate. Careful attention during procedures can help prevent serious adverse events in dural AVF management.

Area of Science:

  • Neurology
  • Interventional Radiology
  • Vascular Surgery

Background:

  • Dural arteriovenous fistulae (dural AVFs) are abnormal connections between dura mater arteries and veins.
  • Endovascular treatment is a primary therapeutic approach for dural AVFs.
  • Understanding periprocedural complications is crucial for patient safety.

Purpose of the Study:

  • To review cases of dural arteriovenous fistulae (dural AVFs).
  • To analyze the periprocedural complications associated with endovascular treatment of dural AVFs.
  • To identify the types and frequency of complications in dural AVF management.

Main Methods:

  • Retrospective review of dural AVF cases undergoing endovascular treatment.
  • Analysis of 157 procedures to identify and categorize periprocedural complications.
  • Classification of complications into subgroups: cranial nerve palsy, coil-related issues, thromboembolism, vessel perforation, and radiation-related problems.

Main Results:

  • A total of 14 complications occurred in 157 procedures, resulting in an overall complication rate of 9%.
  • Complications included transient abducent nerve palsies (n=5), coil unraveling/migration (n=4), thromboembolic events (n=2), and vessel perforations (n=2).
  • One case of venous infarction and one transient neurological deficit (Gerstmann syndrome) were noted.

Conclusions:

  • Serious complications in the endovascular treatment of dural AVFs are rare.
  • Meticulous attention during the procedure is essential for preventing adverse events.
  • The study highlights the safety profile of endovascular dural AVF treatment when performed with care.

Hemodialysis I: Introduction01:25

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...

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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Aneurysm IV: Nursing Management

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
