ABSTRACT
PURPOSE:
Penetrating aortic ulcer (PAU) is a rare etiology of acute aortic syndrome. Few studies exist regarding the perioperative outcome. The aim was to analyze clinical outcome and risk factors of mortality in this treatment population.METHODS:
Retrospective, monocentric study from 2010 to 2021. Clinical data of endovascular or open treated PAU were analyzed. In-hospital mortality was selected as the primary study endpoint. Angio-morphologies were analyzed and risk factors for mortality were identified by using univariate analysis.RESULTS:
Overall, 133 patients were identified. 29% (n=38) of patients presented symptomatically. In 64% (n=85), the PAU was localized in the thoracic aorta. On average, PAUs had a depth of 15.4±10.1 mm and a width of 17.9±9.6 mm. The patients had a median of 2 (95% confidence interval [CI]=2-3) high-risk features (HRF) as PAU depth >10 mm, PAU width >20 mm, aortic diameter >40 mm, symptomatic, intramural hematoma (IMH), pleural effusion. Significantly more HRF were observed in symptomatic patients (p=0.01). 53% (n=71) of patients were treated with thoracic endovascular aortic repair (TEVAR), 41% (n=54) by endovascular aortic repair (EVAR), and 6% (n=8) by open surgery. A hybrid procedure with cervical debranching was performed in 16% (n=21) and complex endovascular repair with fenestrated or branched endografts in 15% (n=20). Overall, complications greater than grade II according to the Clavien-Dindo classification occurred in 19% (n=25) and of the patients. In-hospital mortality manifested in 6% (n=8). Factors associated with increased mortality were the diameter of the aorta >40 mm (88% vs 39%, p=0.03), as well as symptomatic patients (63% vs 26%, p=0.04), coincident IMHs (38% vs 10%, p=0.05), and complex endovascular procedures (50% vs 50% p<0.01). Penetrating aortic ulcer width >20 mm tended to show higher mortality (75% vs 40%, p=0.06). Routine follow-up was available for 89% (n=117) for a median of 39 months (95% CI=25-42). One-year and 5-year survival were 83% and 60%, respectively, with 1 aortic pathology-related death.CONCLUSIONS:
Treatment of PAU is associated with an acceptable perioperative morbidity and mortality. Risk factors associated with increased mortality are an elevated aortic diameter, the presence of IMHs, clinical symptomatology at presentation, and complex endovascular procedures.
