Summary
This study shows that endovascular stent grafting (SG) is a safe and effective treatment for thoracic aortic aneurysms (TAA), with over 96% of patients achieving successful aneurysm exclusion. Further long-term studies are needed to confirm its lasting efficacy.
Area of Science:
- Cardiovascular Surgery
- Medical Devices
- Vascular Interventions
Context:
- Thoracic aortic aneurysms (TAA) repair has seen limited commercial stent graft (SG) availability in Japan until 2008.
- Endovascular thoracic interventions in Japan commenced in the early 1990s, often utilizing homemade devices.
- This research focused on fenestrated SGs for distal arch repairs, a challenging anatomical site.
Purpose:
- To evaluate the efficacy and safety of custom-designed, fenestrated stent grafts for endovascular thoracic aortic aneurysm repair.
- To assess the outcomes of over 1,120 patients treated with endovascular stent grafting over 15 years.
- To analyze the success rate of aneurysm exclusion and endoleak prevention in TAA patients.
Summary:
- Over 1,120 TAA patients were treated using individually designed stent grafts (SG) from 1995 to 2010.
- Fenestrated SGs were utilized for distal arch aneurysms to maintain blood flow to arch vessels.
- Aneurysm exclusion without endoleak was achieved in over 96% of cases within two weeks post-operation.
Impact:
- Endovascular stent grafting demonstrates significant potential as a safe and effective treatment for thoracic aortic aneurysms.
- The study highlights the success of personalized device design in complex TAA cases.
- Further long-term follow-up is recommended to fully establish the durability and long-term efficacy of this endovascular approach.

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...
01:19Anastomoses
In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.

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...
