Summary
A novel Venturi effect double-lumen thrombectomy catheter successfully removed superficial femoral artery thrombus in all seven patients. This minimally invasive approach offers rapid, single-session treatment for acute and subacute arterial blockages.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Medical Device Technology
Background:
- Superficial femoral artery (SFA) thrombus can lead to significant limb ischemia.
- Traditional thrombectomy methods may be invasive and time-consuming.
- Novel catheter-based technologies are needed for efficient thrombus removal.
Purpose of the Study:
- To evaluate the efficacy and safety of a new double-lumen thrombectomy catheter.
- To assess the performance of the Venturi effect-based catheter in treating SFA thrombus.
- To determine the feasibility of single-session diagnosis, thrombectomy, and intervention.
Main Methods:
- A prospective evaluation of a Venturi effect double-lumen thrombectomy catheter.
- Inclusion of seven consecutive patients with SFA thrombus (3 days to 9 weeks old).
- Assessment of procedural success, time to completion, and complication rates.
Main Results:
- Successful thrombectomy was achieved in all seven patients.
- The mean procedure time was less than 20 minutes.
- Five patients underwent successful diagnosis, thrombectomy, and intervention in a single session.
Conclusions:
- The Venturi effect double-lumen thrombectomy catheter is effective for SFA thrombus removal.
- The device facilitates rapid and efficient treatment, potentially enabling single-session interventions.
- This technology represents a promising minimally invasive option for SFA occlusive disease.
