Technical challenges and anatomic anomalies encountered during aortic surgery.

Area of Science:

• Vascular Surgery
• Endovascular Techniques
• Aortic Disease Management

Background:

• Endovascular techniques have revolutionized aortic pathology treatment over the past two decades.
• Indications have expanded from infra-renal to supra-renal, aortic arch, and thoracoabdominal aorta.
• Endovascular approaches now treat dissections, traumatic injuries, penetrating aortic ulcers, and fistulas.

Purpose of the Study:

• To review the evolution and current status of endovascular repair for aortic pathologies.
• To highlight the persistent role and necessity of open surgical repair for complex cases.
• To emphasize the comprehensive skill set required for modern vascular surgeons.

Main Methods:

• Review of clinical applications and outcomes of endovascular aortic repair.
• Analysis of technical failures and management strategies, including conversion to open surgery.
• Discussion of patient-specific factors influencing treatment choice (e.g., age, connective tissue disease).

Main Results:

• Exponential increase in endovascular procedure application across diverse aortic regions and pathologies.
• Occurrence of short-term and long-term technical failures, often managed with repeat endovascular interventions.
• Identification of cases where open surgery remains essential due to limitations of endovascular techniques or patient factors.

Conclusions:

• While endovascular repair is widely adopted, open surgery remains crucial for complex aortic diseases.
• Vascular surgeons must possess proficiency in both endovascular and open surgical techniques.
• Mastery of anatomical variations and unexpected situations is vital for comprehensive aortic disease management.
