ObjectiveTo summarize the clinical data and efficacy of surgical treatment of aortic periannular abscess.MethodsThe clinical data of 35 aortic periannular abscess patients admitted to our hospital from January 2009 to June 2019 were retrospectively analyzed, including 21 males and 14 females, aged 36 to 67 (53.0±12.3) years. Among them, there were 14 patients of native aortic valve endocarditis and 21 patients of prosthetic valve endocarditis (16 patients of mechanical valve and 5 patients of biological valve). Preoperative blood cultures were positive in 15 patients, including 8 patients of Staphylococcus aureus, 2 patients of Staphylococcus epidermidis, 3 patients of Streptococcus grass green, 1 patient of Pseudomonas aeruginosa, and 1 patient of Enterococcus.ResultsEleven patients underwent emergency or urgent surgery. Thirty patients underwent aortic valve replacement, and 5 patients underwent modified Cabrol surgery to replace the aortic root. Early postoperative complications included 1 patient of bleeding, 8 patients of low cardiac output syndrome, 5 patients of renal insufficiency, 10 patients of respiratory insufficiency, 3 patients of tracheotomy, 8 patients of pulmonary infection and 1 patient cerebrovascular accident. The postoperative follow-up period was 6 to 120 (53.6±20.8) months. During the follow-up, 4 patients died and 4 patients were lost. No infection recurred during the follow-up. Perivalval leakage occurred in 3 patients, and one patient underwent occlusion 12 months following the procedure. The survival curve indicated that the 1-year survival rate was 85.5%, and the 5-year survival rate was 67.3%.ConclusionAlthough the lesions of periannular abscesses are complicated and critical, effective perioperative antibiotic treatment, individualized surgical timing, and appropriate surgical strategies can significantly reduce mortality and achieve better results.
