Abscesses in the aortic root are a serious complication of infective endocarditis and require accurate diagnosis for antibiotic and surgical management. Nineteen cases of endocarditis of a native valve or prosthetic valve and adjacent abscess cavities were identified with angiography. Of 6 patients with endocarditis of a native valve, 5 had bicuspid aortic valves and all had severe aortic regurgitation. Of 13 patients with endocarditis of a prosthetic aortic valve, all had paravalvular regurgitation. Abscesses in the aortic root were saccular, ranged from 1 to 3 cm in diameter, and, depending on sinus of origin, extended beneath the main and right pulmonary arteries or into the interventricular septum or mitral anulus. Fistulas were detected into the mitral anulus in 8 patients, and into the right ventricle in 3 patients. No complications from the catheterization were recorded during the 48-hour follow-up.
主动脉根部脓肿是感染性心内膜炎的严重并发症，需要准确诊断以进行抗生素治疗和手术处理。通过血管造影术确诊了19例天然瓣膜或人工瓣膜心内膜炎及相邻脓肿腔的病例。在6例天然瓣膜心内膜炎患者中，5例有二叶式主动脉瓣，且均有严重主动脉反流。在13例人工主动脉瓣心内膜炎患者中，均有瓣周反流。主动脉根部脓肿呈囊状，直径为1至3厘米，根据起源窦不同，可延伸至主肺动脉和右肺动脉下方，或进入室间隔或二尖瓣环。8例患者检测到瘘管通向二尖瓣环，3例通向右心室。在48小时随访期间未记录到导管插入术的并发症。
