Thoracoabdominal Aortic Aneurysms: Experience with 372 Patients
Key result
Atriofemoral bypass during thoracoabdominal aortic resection was associated with a lower risk of postoperative paraplegia or paraparesis compared to no bypass (1.6% vs 7.4%).
Why the study?
Does the use of atriofemoral bypass reduce postoperative neurological complications in patients undergoing thoracoabdominal aortic resection?

Joseph S. Coselli (1994) conducted a cohort in Thoracoabdominal aortic aneurysm (n=372). Atriofemoral bypass vs. No atriofemoral bypass was evaluated on Paraplegia or paraparesis. Atriofemoral bypass during thoracoabdominal aortic resection was associated with a lower risk of postoperative paraplegia or paraparesis compared to no bypass (1.6% vs 7.4%).
