The goal of this study was to assess the management of failed or failing infrainguinal bypasses with distal correctable lesions. A retrospective analysis of 94 procedures was performed for 72 (77%) failed and 22 (23%) failing infrainguinal bypasses with distal correctable lesions in 94 patients. The 94 procedures included 50 (53%) balloon angioplasties and 44 (47%) distal vein graft extensions from the previous graft to the distal artery. Preprocedural thrombolytic therapy was performed in 62 of 94 limbs with a failed graft, and complete thrombolysis was achieved in 30 of 94. The results of thrombolytic therapy (complete or incomplete thrombolysis) or the means of revision procedure (balloon angioplasty or distal vein graft extension) did not affect the patency. Lower patency was observed for women, patients with a secondary bypass, and grafts with multiple episodes of revision. We conclude that the patency of failing infrainguinal bypasses after revision of distal lesions was affected not by means of therapy but by previous vascular procedures, the usual risk factors, and female gender.
