Summary
This presentation explores the diversity of deep vein thrombosis (DVT) treatment devices, with a focus on the new Lightning 12 and Lightning Flash systems for thrombectomy. Through an analysis of the latest advances in DVT devices, Dr. Black highlights the benefits of early thrombectomy and the technical success rates of new mechanical thrombectomy systems. The research demonstrates that the Lightning system excels in improving patient quality of life and reducing the incidence of post-thrombotic syndrome (PTS).
Key Points
1.DVT Treatment Evolution:
•Over the past few years, an increasing number of DVT treatment devices have entered the market, allowing healthcare teams to choose the most appropriate device based on individual patient cases. The Lightning system represents a significant advancement in this area (PPT 4).
2.Early Thrombectomy and Success Rates:
•Early randomized controlled trials, such as the ATTRACT trial, showed that early thrombectomy reduces the risk of moderate to severe PTS. However, early thrombectomy may pose a higher bleeding risk, particularly with the use of thrombolytic agents, making device selection and treatment strategy critical.
3.Application of the Lightning System:
•Lightning 12:
The device has shown impressive results in multiple cases. For example, a 33-year-old female hairstylist experienced stent occlusion after venous stent placement. The Lightning 12 system successfully restored blood flow with no significant post-procedural complications.
•Lightning Flash:
Currently undergoing a multicenter prospective IDE study (NCT05003843), Lightning Flash is showing promising initial results, effectively reducing thrombus burden with a low rate of major adverse events.
Conclusion
•The diversity of DVT treatment devices provides clinicians with more options for successful interventions. The Lightning 12 and Lightning Flash systems have demonstrated high technical success rates and significant potential in reducing the incidence of PTS. Moving forward, DVT treatment will focus on improving device efficiency while minimizing complications, with the Lightning system poised to play a pivotal role.
