Insights

Stent-assisted coiling is a safe and effective treatment for ruptured wide-necked intracranial aneurysms. This method demonstrated no technique-related complications and a low mortality rate in a recent study.

Area of Science:

  • Neurosurgery
  • Interventional Neuroradiology
  • Vascular Neurology

Background:

  • Wide-necked intracranial aneurysms pose significant treatment challenges.
  • Ruptured aneurysms require urgent intervention to prevent rebleeding and improve outcomes.
  • Surgical clipping and balloon-assisted embolization have limitations for certain aneurysm morphologies.

Purpose of the Study:

  • To evaluate the safety and efficacy of stent-assisted coiling for ruptured wide-necked intracranial aneurysms.
  • To report the clinical and angiographic outcomes of this treatment modality.
  • To assess the feasibility of stent-assisted coiling in complex aneurysm cases.

Main Methods:

  • Retrospective review of 19 consecutive patients with ruptured wide-necked intracranial aneurysms.
  • Treatment involved stent-assisted coil embolization.
  • Angiographic follow-up was conducted at a mean of 5.2 months.

Main Results:

  • No technique-related complications were observed.
  • The 30-day mortality rate was 10.5% (two of 19 patients).
  • One patient (5.3%) experienced rebleeding with a poor clinical outcome (Glasgow Outcome Scale score of 2).

Conclusions:

  • Stent-assisted coiling is a feasible and safe endovascular option for ruptured wide-necked intracranial aneurysms.
  • This technique is particularly valuable for aneurysms unsuitable for surgical or balloon-assisted treatment.
  • Further research may explore long-term outcomes and compare with other treatment modalities.

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...

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 I: Introduction

An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
