The study population will include all popliteal aneurysm patients treated with GORE VIABAHN® stent graft in scheduled elective surgery, whether symptomatic or asymptomatic.

The intervention can be performed under local anesthesia (LA), regional locus (ALR) or general anesthesia (AG) (data collected) by first approach: percutaneous or conventional.

The data collected are:

• Number of GORE VIABAHN® stent used (length and diameter of each)
• Embolization of collaterals and other related actions
• Operative complications
• Intraoperative fibrinolysis
• Collar cover> 2 cm
• Lack of overlap in the "overlap zone" (nb: between 4 and 8 cm above the joint spacing)
• Arteriography in profile, kink

Composite criterion associating Target Lesion Revascularization (TLR) and Rate of major amputation.

An Echo-Doppler imaging examination will be performed and the following parameters and information should be collected:

• Permeability
• Intra-stent restenosis
• Systolic pressure index
