The Hydrolyser thrombectomy catheter: a single-center experience
Summary
The Hydrolyser system offers effective mechanical hydrodynamic thrombectomy for arteries and veins. This efficient device achieved 83% technical success, presenting an alternative to surgery and thrombolysis.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Devices
Background:
- Thrombosis in native arteries, veins, and bypass grafts poses significant clinical challenges.
- Percutaneous thrombectomy aims to restore vessel patency with minimally invasive techniques.
Purpose of the Study:
- To evaluate the single-center experience with the Hydrolyser mechanical hydrodynamic thrombectomy system.
- To assess its efficacy in treating thromboses across various vascular beds.
Main Methods:
- The Hydrolyser, a 7F thrombectomy catheter, was used in 41 patients with recent thromboses (1-30 days).
- Occlusions were located in lower limb arteries (n=28), bypass grafts (n=8), and central veins (n=3).
- Adjunctive procedures included angioplasty, thromboaspiration, and thrombolysis.
Main Results:
- Immediate technical success (residual clot <50%) was achieved in 83% of patients (34/41).
- Success rates varied by location: 78% in native arteries, 87% in bypass grafts.
- At 30 days, 73% of treated vessels remained patent, with one distal embolism complication.
Conclusions:
- The Hydrolyser system demonstrates promise as a percutaneous thrombectomy solution.
- It is a quick, reliable, and efficient device.
- It may serve as an alternative to traditional thrombolysis and surgical thrombectomy.
