PURPOSE: to present our clinical experience with a new mechanical hydrodynamic thrombectomy system (Hydrolyser), using the Venturi effect, applied for thrombus removal in native arteries, arterial grafts, venous system and pulmonary arteries (diameter > 5 mm).
MATERIAL AND METHODS: the Hydrolyser, a 7F, double lumen, over the wire catheter, was used in 50 patients (29 males, 21 females), mean age: 66.2 +/- 13.1 years (40-90). Mean occlusion time: 8.7 +/- 7.3 days (1-30), mean thrombus length: 17.7 +/- 10.2 cm (4-35). Thrombus' location: native arteries (35), arterial grafts (9), superior vena cava (2), axillary vein (2), pulmonary artery (2). Approach ways: arterial femoral antegrade (22), retrograde (7), contralateral (14), popliteal arterial (1), veinous femoral (5) and veinous brachial (1).
RESULTS: Immediate technical success in 41 patients (82%): native arteries (27/35), arterial graft (7/9), pulmonary artery (2/2), superior vena cava (2/2) axillary vein (2/2). Percentage of thrombus estimated angiographically to be removed by the Hydrolyser: 72.5 +/- 22%. Adjunctive therapy: angioplasty (38, with 19 immediate stents implantations), thromboaspiration (17), reduced time fibrinolysis (11). One complication: distal embolism cured by thromboaspiration. In 9 patients the procedure failed, requiring surgery.
CONCLUSION: the Hydrolyser system seems a promising concept for percutaneous thrombectomy. It is a quick reliable, efficient device. This technique may also offer an alternative to thrombolysis and surgical thrombectomy.
