Summary
Visceral artery aneurysms (VAAs) are rare. Both open and endovascular repairs show similar outcomes, but minimally invasive endovascular treatments are increasingly preferred for VAAs.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Abdominal Imaging
Background:
- Visceral artery aneurysms (VAAs) are uncommon, with an incidence of 0.01% to 0.2%.
- This study analyzes 40 years of VAA treatment at a Chilean academic institution.
Purpose of the Study:
- To describe clinical characteristics of VAAs.
- To evaluate treatment outcomes for surgically treated VAAs.
Main Methods:
- Retrospective single-center study (1982-2023).
- Analysis of patient demographics, aneurysm details, and treatment modalities.
- Comparison of open surgery versus endovascular procedures.
Main Results:
- 64 VAAs in 59 patients (59.3% female, median age 51).
- Most common: renal (50%) and splenic (31.3%) artery aneurysms.
- Endovascular repair (42.2%) and open surgery (57.8%) showed similar technical success (100% vs 97.0%) and low complication rates (6.7%).
- A trend towards endovascular repair was observed over time, with smaller aneurysms treated in the later era.
Conclusions:
- Open and endovascular repair of VAAs yield comparable surgical outcomes.
- Current trends favor endovascular interventions due to their less invasive nature.

01:11Overview of Systemic Arteries
The human body is a complex, well-organized machine, and at the heart of its operations lies the circulatory system. This network of blood vessels, which includes systemic arteries, plays a vital role in maintaining life by transporting nutrients, oxygen, and waste products to and from cells throughout the body.
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.

01:25Abdominal Aorta
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

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...
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...
