Thoracic stent-graft

Area of Science:

• Vascular Surgery
• Interventional Cardiology
• Biomedical Engineering

Background:

• Stent-grafts, devices integrating stents and vascular grafts, are inserted via image-guided interventional procedures.
• Early experiments in 1986 demonstrated stent-graft feasibility in animal aortas.
• Clinical applications for abdominal aortic aneurysms emerged in the early 1990s.

Purpose of the Study:

• To review the development and application of stent-grafts in treating aortic pathologies.
• To compare the advantages and disadvantages of abdominal versus thoracic stent-graft procedures.
• To highlight the potential of stent-grafts as an alternative to surgical interventions.

Main Methods:

• Review of historical experimental and clinical reports on stent-graft technology.
• Analysis of procedural challenges and benefits associated with thoracic stent-graft placement.
• Examination of early studies on endovascular stent-graft use for thoracic aortic aneurysms and dissections.

Main Results:

• The first stent-graft experiment was reported in 1986, with clinical use for abdominal aortic aneurysms starting in the early 1990s.
• Thoracic stent-grafts face challenges like aortic arch curvature and device caliber but offer less invasive treatment than surgery.
• Studies in 1994 demonstrated successful transluminal placement for thoracic aortic aneurysms and use for aortic dissection.

Conclusions:

• Stent-graft technology has evolved significantly since its inception.
• Thoracic stent-grafting presents unique challenges but provides a less invasive option compared to open surgery.
• Stent-grafts are emerging as a crucial alternative to surgical treatment for various aortic conditions.
