Summary
Advanced endovascular aortic repair (EVAR) offers solutions for complex aortic aneurysms. This review details imaging techniques for surveillance and troubleshooting these advanced EVAR procedures.
Area of Science:
- Vascular Surgery
- Medical Imaging
- Radiology
Background:
- Conventional endovascular aortic repair (EVAR) is unsuitable for certain anatomically challenging aortic aneurysms.
- Advanced EVAR techniques and customized devices now enable treatment in these complex cases.
- Challenging proximal and distal landing zones can be addressed with fenestrated/branch devices and specific graft configurations.
Purpose of the Study:
- To provide an imaging review of advanced endovascular aortic repair (EVAR) techniques.
- To illustrate the CT appearance of advanced EVAR in routine and complicated scenarios.
- To describe novel CT angiography (CTA) techniques for troubleshooting advanced EVAR.
Main Methods:
- Review of literature on advanced EVAR imaging.
- Illustration of CT appearances using conventional CTA.
- Demonstration of novel CTA techniques for problem-solving.
Main Results:
- Advanced EVAR utilizes customized devices and modified techniques for challenging landing zones.
- Fenestrated/branch devices, chimney/periscope, iliac branch grafts, and sandwich techniques address proximal and distal challenges.
- CT angiography (CTA) is essential for lifelong surveillance of advanced EVAR.
Conclusions:
- Advanced EVAR expands treatment options for anatomically complex aortic aneurysms.
- Lifelong surveillance with CTA is critical due to the novelty of these techniques.
- This review highlights key imaging findings and troubleshooting techniques for advanced EVAR.

01:21Aneurysm 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...
01:26Aneurysm 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...
01:19Imaging Studies VII: Vascular Imaging
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...
01:22Aortic 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...
01:30Aneurysm 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...
