A number of percutaneous mechanical thrombectomy devices are currently being used or undergoing clinical evaluation for the treatment of acute and chronic limb-threatening ischemia. Preliminary studies on the safety, efficacy, and device limitations have spurred an interest in percutaneous techniques for thrombus debulking as stand-alone therapy or an adjunct to pharmacologic thrombolysis. The devices have various mechanisms or combinations of mechanisms to optimize thrombus removal. Efficacy of thrombus removal is balanced by the propensity for vessel wall damage and distal embolization, especially for wall-contact devices (Arrow-Trerotola device and Cragg and Castañeda brushes). Initial experience in hemodialysis graft occlusion has subsequently moved on to peripheral arterial occlusions. Although the U.S. Food and Drug Administration has approved eight mechanical thrombectomy devices (MTDs) for use in thrombosed hemodialysis grafts, only the AngioJet LF140 is currently approved for use in peripheral arterial occlusive disease. Nevertheless, numerous clinical articles and abstracts have reported the "off-label" use of MTDs in the management of limb-threatening ischemia. A description of the eight MTDs and a review of the current literature on use of MTDs for acute peripheral arterial occlusive disease are provided.
