Summary
This study details surgical repair of a descending aortic aneurysm in a patient with Takayasu's disease. Advanced techniques successfully treated complex vascular lesions, preventing complications.
Area of Science:
- Cardiovascular Surgery
- Vascular Surgery
- Rheumatology
Background:
- Takayasu's disease, a rare inflammatory condition, can lead to complex aortic pathologies.
- Surgical management of descending aortic aneurysms in patients with Takayasu's disease presents significant challenges due to associated vascular lesions.
Observation:
- A 69-year-old female patient with Takayasu's disease presented with a descending aortic aneurysm, abdominal aortic stenosis, and severe descending aorta calcification.
- Preoperative imaging (angiography and CT) guided the surgical strategy.
- The surgical approach involved staged repair: abdominal aorta replacement followed by descending aortic aneurysm resection.
Findings:
- The abdominal aorta was addressed first to ensure adequate blood flow during extracorporeal circulation for the thoracic procedure.
- Femoro-femoral bypass was utilized for the descending aortic aneurysm resection.
- Two occlusion balloon catheters facilitated aortic clearing, and decalcification of aortic walls enabled successful anastomosis of a prosthetic tube graft.
- Minimal sacrifice of intercostal arteries (2 pairs) was performed, successfully preventing paraplegia.
Implications:
- Accurate preoperative evaluation of vascular lesions is critical for successful surgical outcomes in Takayasu's disease.
- Tailored surgical techniques, including staged repair and specialized aortic clearing methods, are essential for managing complex aortic aneurysms in this patient population.
- This case highlights the feasibility of complex aortic reconstruction in Takayasu's disease, emphasizing the importance of individualized surgical planning to avoid neurological deficits.
