Summary
The BAlloon Deployment using FORcible Manner (BADFORM) technique shows acceptable efficacy and safety for challenging arterial lesions. This novel endovascular method aids device delivery in cases of chronic total occlusions or calcified blockages.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Endovascular Techniques
Background:
- Peripheral artery disease (PAD) treatment relies on endovascular techniques (EVT).
- Difficulties in device delivery persist, particularly with long chronic total occlusions or calcified lesions.
- The BADFORM technique is proposed to overcome these challenges.
Purpose of the Study:
- To evaluate the efficacy and safety of the novel BADFORM technique.
- To assess the utility of BADFORM in complex arterial lesions.
Main Methods:
- Retrospective review of ten EVT cases using BADFORM (April 2015 - September 2016).
- Wire externalization achieved via rendezvous technique.
- BADFORM employed when antegrade device passage failed; involved retrograde pulling of an externalized wire.
Main Results:
- All patients had critical limb ischemia and were on hemodialysis.
- Lesions were severely calcified (100%) and chronic total occlusions (90%).
- Technical success rate was 90%, procedure success rate was 70%; one minor vessel injury occurred.
Conclusions:
- The BADFORM technique demonstrates acceptable efficacy and safety.
- This technique may be a valuable option for complex endovascular interventions.
