title: Endovascular treatment of surgically implanted arterial graft thrombosis by using manual aspiration thrombectomy.
abstract: The purpose of this study was to present our experience with guiding catheters in manual aspiration thrombectomy of occluded infra-aortic bypass grafts. This material was designed as a guiding catheter but was also used for thrombus aspiration. Six consecutive patients (all male; mean age, 61.0±5.7 years; range, 54-68 years) who underwent manual aspiration thrombectomy at the discretion of the operator for infra-aortic bypass graft thrombosis between 2002 and 2010 were retrospectively reviewed. The angiographic success described as either stenosis or residual thrombus less than 30% was 67%. Primary patency was 50%, and secondary patency was 66.7%. Additional stents were needed in four lesions of three patients. Manual aspiration thrombectomy is intended to remove both soft acute blood clots and hard organized embolic and thrombotic obstructions. Manual aspiration thrombectomy appears to be a safe and effective method for treating delayed graft thrombosis. This method provides an alternative to surgical thrombectomy, especially for patients who are not good candidates for the surgery.
