Multiple aneurysms in dacron velour graft.

Fomation of an aneurysm in a Dacron graft is a rare complication. It usually occurs within two years from operation. Most cases take the form of a generalized dilation. Multiple saccular aneurysms developed in a patient with a Dacron velour graft. The cause of the complication is not always clear, but multiple defects in the construction of the Dacron graft seemed the most likely cause in this case.
