Endovascular Thoracoabdominal Replacement after Total Abdominal Aortic Debranching

Area of Science:

• Cardiovascular Surgery
• Genetics
• Vascular Medicine

Background:

• Marfan syndrome is a genetic disorder affecting connective tissue, primarily impacting the cardiovascular system.
• Aortic pathologies, such as aneurysms and dissections, are life-threatening complications in Marfan syndrome.
• Previous surgical interventions for aortic disease can complicate subsequent treatment strategies.

Purpose of the Study:

• To present a case of Marfan syndrome with a complex thoracoabdominal aortic aneurysm.
• To illustrate the successful application of endovascular stent grafting in a patient who refused conventional open repair.
• To highlight an alternative treatment option for challenging aortic pathologies in Marfan syndrome.

Main Methods:

• The patient, diagnosed with Marfan syndrome and a history of multiple aortic surgeries, presented with a thoracoabdominal aortic aneurysm.
• Conventional open repair was strongly refused by the patient.
• The patient underwent abdominal debranching followed by a thoracoabdominal endovascular stent graft procedure.

Main Results:

• The endovascular stent grafting procedure was successfully performed.
• The patient's complex thoracoabdominal aortic aneurysm was treated effectively.
• This approach offered a viable alternative to open repair in a high-risk patient.

Conclusions:

• Endovascular stent grafting, combined with abdominal debranching, can be a successful treatment for complex thoracoabdominal aortic aneurysms in Marfan syndrome patients.
• This minimally invasive technique provides an alternative for patients who are not candidates for or refuse traditional open surgical repair.
• Careful patient selection and surgical planning are crucial for optimal outcomes in complex aortic interventions.
