Abstract: | The patient was a 77-year-old man with sudden-onset chest and back pain. Computed tomography angiography (CTA) from the abdomen to the proximal thigh showed an aortic aneurysmal dissection (AAD) and a left deep femoral artery (DFA) aneurysm. The AAD was conservatively managed as there was no sign of increase. The left DFA aneurysm was surgically resected to avoid complications such as rupture, thromboembolism, and limb ischemia. On follow-up CTA obtained 3 weeks later, a spontaneous AVF in a varicose vein of the right DFA was noted. There were no symptoms associated with the AVF, and he was conservatively managed. However, the varicose vein gradually increased, and he underwent successful transarterial catheter embolization (TAE) with metal coils without any complications. After vascular repair of the aneurysm and the AVF of the right DFA, there was no sign of recurrence. |
