Аннотация
BACKGROUND: Brain abscesses can develop with Tetralogy of Fallot and pulmonary anterior venous fistula with large right-to-left shunt. However, some patients exhibit cryptogenic brain abscess (CBA) in the absence of any such congenital disease or other infections. Patent foramen ovale (PFO) is a very common disease that exhibits right-to-left shunt. This study reports the potential for concern between CBA and PFO.
METHODS: We enrolled patients with CBA in our hospital between January 2003 and January 2013. Patients underwent transesophageal echocardiography (TEE) with contrast medium to investigate the presence of PFO.
RESULTS: Seven patients were included. Four were females, and the mean age was 67.7 ± 9.2 years. In all patients, TEE failed to reveal any new findings, however, six patients had PFO, and another patient had pulmonary arteriovenous shunt. Four patients had odontopathy.
CONCLUSION: In this study, all CBA patients exhibited right-to-left shunt. CBA might be caused by paradoxical embolization of a bacterial mass via PFO. Thus, more patients with CBA need to undergo TEE to detect PFO.
