Insights

This study on aortic aneurysms and dissections in Colombia found infrarenal abdominal aortic aneurysms were most common. Larger aortic diameter predicted mortality in aneurysm cases, but not in dissections.

Area of Science:

  • Vascular Surgery
  • Radiology
  • Epidemiology

Background:

  • Aortic aneurysms and dissections are critical vascular conditions with significant mortality.
  • Accurate characterization of anatomical and clinical features is vital for improving diagnosis and treatment.
  • Colombian patient data is crucial for understanding regional variations in these diseases.

Purpose of the Study:

  • To detail the demographic, clinical, and imaging-based anatomical characteristics of aortic aneurysms and dissections.
  • To analyze predictors of in-hospital mortality in this Colombian cohort.
  • To provide region-specific data for Latin American clinical decision-making.

Main Methods:

  • Retrospective, descriptive, observational study of 539 adult patients.
  • Inclusion criteria: radiologically confirmed aortic aneurysm or dissection via CTA (2010-2021).
  • Data extracted: demographic, clinical, morphological. Statistical analysis: chi-squared, Mann-Whitney U, logistic regression.

Main Results:

  • Infrarenal abdominal aortic aneurysms were most frequent (63.7%); 92% were fusiform.
  • Saccular aneurysms were more common in females and non-infrarenal segments.
  • Aortic diameter independently predicted mortality in aneurysm patients (OR=1.03), but no significant predictors were found for dissection mortality.

Conclusions:

  • Infrarenal location and fusiform shape are predominant in this Colombian cohort.
  • Morphological patterns correlate with sex and anatomical distribution.
  • While trends exist, specific mortality predictors for aortic dissections remain elusive in this population, emphasizing the need for tailored, region-specific management.

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

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...

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
