Effect of drug-coated balloons in treatment of stenosis of the femoral artery and vein bypass graft not responding to plain old balloon angioplasty: a case report

摘要

Computed tomography angiography after distal bypass surgery. The reversed saphenous vein bypass is shown with a red bracket. The proximal anastomotic site was focused in another window. Intra-arterial digital angiography before percutaneous transluminal arterioplasty with drug-coated balloons (DCBs). The stenosed area of the reversed saphenous vein graft is shown with a yellow bracket and the bypass graft is shown with a red arrow. Intra-arterial digital angiography after PTA with DCB. The stenotic lesion was successfully dilated using a DCB. Another re-stenotic lesion was shown below without PSV increase, for which we dilated with DCB
