Evaluation of GORE® VIABAHN® Endoprosthesis for Popliteal Artery Aneurysm

The primary objective is to evaluate the safety and efficacy of the GORE® VIABAHN® Endoprosthesis for the treatment of subjects with Popliteal Artery Aneurysms. The study population includes subjects with an asymptomatic aneurysm (≥ 2 cm diameter) of the popliteal artery, symptomatic aneurysm (no diameter requirement) of the popliteal artery, or presence of mural thrombus (no diameter requirement) of the popliteal artery treated with the GORE® VIABAHN® Endoprosthesis between January 1, 2002 and December 31, 2010. Starting with most recently treated within the above date range, patients meeting Inclusion/Exclusion will be enrolled, until a minimum of 50 subjects with adequate follow up to determine primary endpoints through 12 months will be provided.
