Insights

Endovascular treatment of complex intracranial aneurysms (CIAs) is challenging, with a higher rate of procedure abortion compared to non-complex cases. Careful consideration of CIA criteria is vital for invasive treatment planning.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Interventional Radiology

Background:

  • Complex intracranial aneurysms (CIAs) present unique challenges due to size, location, and morphology.
  • These factors necessitate specialized approaches for effective treatment.

Purpose of the Study:

  • To evaluate the outcomes of endovascular treatment for CIAs.
  • To compare the results of CIA treatment with non-complex aneurysms (nCIAs).

Main Methods:

  • Authors developed specific criteria to identify CIAs among endovascularly treated aneurysms (2008-2014).
  • Clinical outcomes were assessed using the Glasgow Outcome Scale (GOS), and radiological outcomes using the Montreal Scale.
  • Aneurysm localization, procedure abortion rates, and intraoperative complications were analyzed.

Main Results:

  • Internal carotid artery was the most frequent location for both CIAs and nCIAs.
  • CIAs had a significantly higher incidence of aborted procedures (25% vs. 7%) and worse Montreal scores compared to nCIAs.
  • Patients with CIAs and subarachnoid hemorrhage (SAH) showed significantly worse clinical outcomes (GOS) than those with nCIAs and SAH.

Conclusions:

  • The proposed criteria for classifying CIAs are important for diagnosis and treatment planning.
  • Identifying an aneurysm as complex increases the likelihood of aborting endovascular procedures due to technical difficulties.

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...

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...

Protein Complex Assembly02:41

Protein Complex Assembly

Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Protein Complexes with Interchangeable Parts

Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Complex Numbers

The real number system cannot represent the square root of a negative number, which restricts solutions for certain equations, such as quadratics with negative discriminants. To address this, the complex number system was developed, introducing the imaginary unit i, where i = √(-1). This extension allows for the representation of all roots, including those involving negative radicands.A complex number is written in the form x + yi, where x and y are real numbers. Here, x represents the...
