Insights

The Atlas stent demonstrated superior aneurysm occlusion rates and reduced in-stent stenosis compared to the LVIS Jr stent in stent-assisted coiling procedures. This study highlights Atlas as a potentially more effective option for treating brain aneurysms.

Area of Science:

  • Neurosurgery
  • Interventional Neuroradiology
  • Vascular Neurology

Background:

  • Limited comparative data exists for LVIS Jr and Atlas stent-assisted coiling.
  • Previous case series suggest safety and efficacy for both devices individually.

Purpose of the Study:

  • To clinically compare LVIS Jr and Atlas stents for aneurysm coiling.
  • To evaluate and emphasize comparative rates of technical success and complications.

Main Methods:

  • Retrospective analysis of an institutional endovascular database.
  • Inclusion of aneurysms treated with LVIS Jr or Atlas stent-assisted coiling.
  • Evaluation of demographic data, aneurysm characteristics, procedural details, complications, and angiographic outcomes.

Main Results:

  • Atlas stent group (37 patients) vs. LVIS Jr stent group (27 patients).
  • Higher initial Raymond 1 occlusion with Atlas (57% vs. 41%, P=0.03).
  • Greater final Raymond 1 or 2 occlusion (100% vs. 81%, P=0.04) and lower in-stent stenosis (0% vs. 19%, P=0.04) with Atlas.
  • No significant difference in ischemic complications between groups.

Conclusions:

  • Atlas stent-assisted coiling achieved superior aneurysm obliteration rates compared to LVIS Jr.
  • Atlas stent placement was associated with significantly lower rates of in-stent stenosis.
  • Atlas may offer improved long-term outcomes in stent-assisted coiling for aneurysms.

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

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...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Multiple Comparison Tests01:13

Multiple Comparison Tests

Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

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...

Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
