Abstract

Insights

Multidetector CT (MDCT) effectively detects endoluminal thrombosis after endovascular aneurysm repair. This imaging technique aids in diagnosing thrombosis in patients undergoing aortic abdominal aneurysm repair.

Area of Science:

  • Vascular Surgery
  • Radiology
  • Medical Imaging

Background:

  • Endovascular repair is a common treatment for aortic abdominal aneurysms.
  • Post-procedural thrombosis can be a complication following endovascular aneurysm repair.
  • Accurate imaging is crucial for monitoring treatment success and detecting complications.

Purpose of the Study:

  • To evaluate the imaging findings of endoluminal thrombosis in patients who underwent endovascular repair of aortic abdominal aneurysms.
  • To assess the utility of MDCT in diagnosing thrombosis after this procedure.

Main Methods:

  • A retrospective review of 30 patients who underwent endovascular repair of aortic abdominal aneurysms.
  • MDCT imaging was performed using a 64-slice scanner, 5 to 29 months post-treatment.
  • Imaging findings were analyzed for the presence and type of endoluminal thrombosis.

Main Results:

  • Thrombosis was identified in 10 out of 30 patients (33.3%).
  • Complete thrombosis of an iliac branch was observed in three patients.
  • MDCT demonstrated various forms of endoluminal thrombosis.

Conclusions:

  • MDCT is a valuable tool for diagnosing endoluminal thrombosis after endovascular repair of aortic abdominal aneurysms.
  • The findings highlight the prevalence of thrombosis in this patient cohort.
  • MDCT should be encouraged in clinical practice for post-procedural surveillance.

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...

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 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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...
