ABSTRACT
Background:
Primary percutaneous intervention (PPCI) of the saphenous vein graft (SVG) is associated with a high risk of distal embolization and no reflow, since SVG lesions are often very friable and have a large thrombotic burden. We report a case of successful PPCI of the SVG using guide catheter thrombectomy with novel double wire technique. Casesummary:
A 60-year-old male with a past history of coronary artery bypass grafting presented with acute thrombotic occlusion of the SVG to the obtuse marginal graft. Despite appropriate pharmacotherapy (GPIIb/IIIa inhibitors) and thrombosuction, there was a large residual thrombus burden with poor distal flow. In the present case, we decided to perform guide catheter thrombosuction. An exchange length floppy 0.014' wire was passed alongside the pre-existing wire and the 6 Fr JR guide catheter was exchanged for a less traumatic 5 Fr JR guide catheter over the exchange wire. The first wire was kept distally in the vessel along the guiding catheter to maintain the access to the graft vessel. The 5 Fr JR guide catheter was slowly advanced over the wire to the distal portion of the graft, keeping the other wire in the distal portion of the graft to maintain access. A large amount of thrombus was aspirated and the patient improved dramatically.Discussion:
This double wire technique is an effortless and novel way to maintain access to the distal vasculature of the occluded artery, while the guide can be safely intubated deep into the coronary artery that helps in removing a very large amount of thrombus because of their larger internal lumen.
