Total aorta replacement in takayasu arteritis presenting as mega aorta.

Area of Science:

• Cardiovascular Surgery
• Vascular Surgery
• Rheumatology

Background:

• Takayasu arteritis is a rare, chronic inflammatory condition affecting large arteries, primarily the aorta.
• Aneurysmal degeneration of the aorta is a serious complication of Takayasu arteritis, posing significant surgical challenges.
• Optimal management strategies for extensive aortic involvement remain an area of active investigation.

Observation:

• The case involved a patient with extensive aneurysmal dilatation across the entire aorta, from the ascending aorta to the aortic bifurcation.
• A two-stage surgical approach was meticulously planned and executed to address the complex aortic pathology.

Findings:

• Successful completion of a two-stage total aortic replacement, encompassing the ascending aorta, aortic arch, descending thoracic aorta, and abdominal aorta up to the bifurcation.
• The surgical intervention effectively managed the extensive aneurysmal disease secondary to Takayasu arteritis.

Implications:

• This case demonstrates the feasibility and success of a staged total aortic replacement in managing complex aortic aneurysms in Takayasu arteritis.
• The findings may inform surgical decision-making and technique for similar challenging cases.
• Highlights the importance of a multidisciplinary approach in managing rare vascular inflammatory diseases.
