Introduction
Degenerative aneurysms of deep femoral arteries are extremely rare,
accounting for 1-2.6% of all femoral artery
aneurysms(1). They are difficult to diagnose in the
early stage and found in large size at presentation because they are
located deeply and covered by several muscles(2). Deep
femoral artery aneurysm (DFAA) can cause complicated conditions such as
rapid expansion, rupture, and acute lower limb ischemia due to distal
embolism of thrombus. Repair is always recommended for DFAA because of
the possibility of those complications(3). We herein
report either surgical or endovascular treatment of three cases of DFAA.
