Abstract:A 69-year-old man presented with precordial pain and a dilated ascending aorta with the suspicion of an intramural hematoma. At emergency operation, the aorta appeared grossly thickened with diffuse intimal scarring. Retrospectively, the patient tested positive to serologic screening for syphilis with histologic findings also compatible with a syphilitic aortitis.
“…Since ascending and thoracic aorta are rich in lymphatics, spirochetes have tropism for these aortic segments. [10][11][12][13] The tendency of spirochetes to dwell in the small vessels of the vasa vasorum leads to an adventitial chronic inflammation, mainly in the arterioles that perfuse the media layer. 6 The immune system response involves infiltration of plasmacytes and lymphocytes into the aortic wall layers, creating a diffuse and fibrous thickening of the intima.…”
Syphilitic aortitis is a rare complication of tertiary syphilis, which can lead to aortic aneurysm formation, aortic valvular insufficiency, and ostial coronary stenosis. Syphilis has re-emerged worldwide over recent decades and vascular surgeons should be aware of its cardiovascular manifestations. Atypical clinical presentation, such as hemoptysis and a computed tomography angiography pattern of a thicker aneurysmal wall with ulcer-like aneurysm projections, should raise suspicion of syphilitic aortic aneurysm. An early diagnosis and appropriate surgical and medical therapies significantly contribute to successful treatment and favorable prognosis. Herein is reported the case of an 82-year-old male patient, positive for syphilis infection, with impending aortic arch aneurysm rupture treated with a hybrid arch repair. After 7 months, the patient was brought to the emergency room in cardiac arrest. Unsuccessful cardiopulmonary resuscitation maneuvers were performed, and an autopsy showed cardiac tamponade due to rupture of the ascending aorta.

Agentes infecciosos têm papel relevante na patogênese de vasculites sistêmicas “primárias” e podem funcionar como gatilhos para recidivas de doença. Porém, em algumas situações, como na poliarterite nodosa e na vasculite crioglobulinêmica, agentes infecciosos são agentes etiológicos que participam diretamente no desenvolvimento da vasculite e requerem tratamento específico para que o processo vasculítico seja completamente controlado. Agentes infecciosos também podem invadir diretamente a parede do vaso sanguíneo e levar a alterações arteriais que simulam vasculites primárias. Neste artigo, revisaremos as principais formas de vasculites associadas a agentes infecciosos e aquelas causadas diretamente pela invasão da parede do vaso por patógenos.
