Enlarged Ulcer-like Projection and Acute Arterial Embolism in the Lower Limbs of a Patient with Chronic Stanford Type B Aortic Dissection

We report a rare case of thromboembolism in the lower limbs in a 62-year-old male who presented with chest and back pain and was diagnosed with Stanford type B acute aortic dissection with a patent false lumen. Computed tomography revealed a thrombosed false lumen and ulcer-like projection, without expansion of the aortic dimension. He was discharged on the 12th day. However, on the 52nd day of illness, he presented with chest and back pain, elevated C-reactive protein and an enlarged ulcer-like projection on computed tomography. Seven days later, he experienced sudden left leg pain and sensory disturbance. Arteriography revealed right popliteal artery occlusion. Thrombus aspiration and percutaneous transluminal angioplasty were performed for recanalization. Aortic dissection with a false lumen was speculated as the embolization source and surgery was performed. His symptoms resolved after surgery?.
