Isolated true atherosclerotic aneurysms of the deep femoral artery. Case report and literature review.

Isolated true atherosclerotic aneurysms of deep femoral artery are rare. We report on a case of an isolated (DFA) aneurysm of a large size. In reviewing the literature, the great latency of the disease, the high complication rate at presentation and the significant incidence concomitant aneurysms elsewhere are emphasized. Duplex scanning followed by angiography should be performed in order to establish the diagnosis, and to plan the operation. Twenty four cases have been reported so far. Elective surgical treatment is associated with little risk to the patient and avoids the need for emergent operations.
