SPONTANEOUS OBLITERATION OF A PSEUDO-ANEURYSM COMPLICATING AN AORTIC HOMOGRAFT

Pseudoaneurysm formation after aortic homograft replacement in patient s with active endocarditis is a common observation and usually occurs at the site of a former abscess or paravalvular leak in case of prosth etic valve endocarditis. A 53-year-old man with prosthetic endocarditi s underwent aortic valve homograft replacement and developed a pseudoa neurysm at the right and noncoronary aortic sinus which was documented by Doppler echocardiography. Follow-up examination ten months after o peration unexpectedly revealed a complete obliteration of the previous ly echo free space between the homograft and the native aortic root an d, thus, spontaneous obliteration of the pseudoaneurysm.
