Placement of aortic endoprostheses.

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Disease Management

Background:

• Endovascular stent-grafting is increasingly utilized for abdominal and thoracic aortic lesions, representing 60% of elective treatments.
• This technique demonstrates reduced morbidity and mortality rates compared to open surgical repair.
• Despite its advantages, suboptimal outcomes include a 9% rate of residual endoleaks at six months post-procedure.

Purpose of the Study:

• To evaluate the current status and outcomes of endovascular stent-grafting for aortic lesions.
• To highlight the benefits and limitations of endovascular repair in comparison to classical surgical methods.
• To discuss the implications of anesthetic management and future directions for aortic interventions.

Main Methods:

• Review of current practices in endovascular stent-grafting for aortic diseases.
• Analysis of morbidity, mortality, and complication rates, specifically residual endoleaks.
• Discussion of anesthetic management protocols and postoperative care requirements.

Main Results:

• Endovascular stent-grafting is the elective treatment for 60% of abdominal or thoracic aortic lesions.
• Morbidity and mortality rates are significantly lower than with classical repair.
• A notable 9% rate of residual endoleaks was observed at six months, indicating suboptimal results.

Conclusions:

• Endovascular stent-grafting is a valuable, less invasive option for aortic lesions, offering survival benefits.
• Ongoing research and technological advancements are crucial to address suboptimal outcomes like residual endoleaks.
• Future developments aim for emergent treatment of ruptured aortas and reduced late endoleak rates.
