A 69-year-old man was transferred to our hospital with local chest trauma caused by an electric sander impact. Contrast-enhanced CT revealed Stanford type A aortic dissection with an ulcer-like projection at the level of the sino-tubular junction (STJ), and pericardial effusion. Emergency surgery was performed. Although no penetrating injury was found in the adventitia of the ascending aorta, we identified an intimal tear of the anterior circumference of the STJ. This led us to a diagnosis of traumatic aortic dissection. We performed replacement of the ascending aorta. We reported a rare case of blunt trauma–induced ascending aorta dissection.

A case of a 77-year-old female with a syphilitic abdominal aortic aneurysm (AAA) is reported. Despite the rarity of syphilitic vasculitis today, increasing infection rates make it a relevant concern. The patient underwent successful open surgical repair with a Y-graft. Pathological findings, including medial elastic fiber loss and inflammatory cell clusters, were consistent with syphilitic aortitis. Although postoperative antibiotic treatment reduced Rapid Plasma Reagin (RPR), the patient developed a type B aortic dissection 395 days after surgery. This highlights that patients with syphilitic aortitis require vigilant, long-term aortic monitoring even after surgery.
