Abstract:
Objective: Isolated abdominal aortic dissection (IAAD) co-occurring with an abdominal aortic aneurysm (AAA) is rather rare. The objective of this report was to discuss the adequate timing and method of surgery for this condition. Patients: We encountered two operative cases, for which we carefully considered the timing and method of surgery. One patient underwent open repair 1 month after the onset, and the other patient underwent endovascular aneurysm repair (EVAR) 3 years after the onset. Results: Both patients had a good postoperative recovery and are doing well 8 months after the surgery. Conclusion: The presence of symptoms or an increase in the diameter of an AAA is important in determining the timing of intervention.
