Abstract:
We report a case of a 55-year-old male with type B-chronic aortic dissection. Patient presented with intermittent claudication due to limb malperfusion resulting from expansion of a patent false lumen during walking regardless of normal range ankle-brachial index (ABI) at rest. Preoperative stress vascular ultrasonography was an effective modality for proper diagnosis. We should be concerned of reversible ischemia due to the dissection flap in patients with type B aortic dissection. Fenestration of the aorta can be a choice of treatment in such patients. The patient has been doing well with no ischemia for 3.5 years after the operation.
