Percutaneous interventions of Cabrol graft with aspiration thrombectomy and stenting have been previously described. We report a patient who successfully underwent percutaneous intervention on the graft by rheolytic thrombectomy followed by stenting in the setting of ST elevation myocardial infarction.展开更多

Eight French and 12 F aspiration catheters were used to aspirate the thrombus in the right–pulmonary-artery model, 8 French and 14 F aspiration catheters were used in the inferior–vena cava model, and 8 French and 10 F aspiration catheters were used in the left-–iliofemoral-vein model. A thrombus filtration and auto-blood reinfusion bottle was used to filter the thrombus and re-infuse auto-blood. We evaluated the thrombus aspiration capability of each catheter by comparing preaspirated with the post-aspirated thrombus volume, and we evaluated the difference in aspiration capability between the two catheters in each model by comparing their thrombus aspiration rates. We used Student’s t-test for statistical analysis.Results: Differences between pre-aspirated and post-aspirated thrombus volumes for each catheter were insignificant, as were those between the thrombus aspiration rates of the two catheters in each venous model. Using the thrombus aspiration and auto-blood reinfusion system, each aspiration catheter could fluently aspirate the thrombus out of the venous model.Conclusion: In this study, we designed a new venous-thrombus aspiration system. This system could be used to aspirate acute venous thrombi and re-infuse autologous blood.展开更多
