Abstract Angiographic thrombus is associated with poorer procedural and clinical outcomes. We report our experience with the X‐Sizer thrombectomy device (EndiCOR Medical) from March 2001 to December 2002. Indications for use in 44 patients (33 male; mean age, 60) included myocardial infarction (27), unstable angina (6), periprocedural thrombosis (2), acute (< 24 hr) stent thrombosis (1), and subacute (> 24 hr) stent thrombosis (8). Three cases involved vein grafts. Deployment was successful in 42/44. Difficulty traversing the stent occurred in 5/9 cases of in‐stent thrombosis. Median TIMI flow increased from 1 to 2 ( P = 0.01) postthrombectomy. Median final TIMI flow was 3. Complications included dissection (1), perforation, device jam on stent (1), disruption of a covered stent (1), distal macro‐embolization (4), and transient no‐reflow (5). The X‐Sizer thrombectomy device improves TIMI flow but does not always prevent distal embolization. Care is needed when treating in‐stent thrombosis.
