Clinical outcome of low-dose and high-dose drug-coated balloon angioplasty with intraplaque wiring for femoropopliteal chronic total occlusion lesions.

Chronic total occlusion (CTO) lesions of the femoropopliteal artery have been shown to benefit from drug-coated balloon (DCB) angioplasty. However, because bailout stenting is often performed, the outcome of DCB angioplasty alone remains unknown, particularly the differences in outcomes between low-dose DCB (LD-DCB) and high-dose DCB (HD-DCB). To address these issues, we conducted a single-center, retrospective cohort study and enrolled 66 consecutive patients undergoing initial endovascular therapy with DCBs for femoropopliteal CTO lesions from June 2018 to February 2023.

Dissection and re-entry techniques are essential to achieve safe and effective chronic total occlusion recanalization. Several studies have demonstrated similar outcomes following extraplaque stenting compared with intraplaque stenting. Dissection techniques most often involve the use of knuckled wires to progress within and beyond the chronic total occlusion segment.

Article Synopsis
- Antegrade techniques are methods used to treat blocked heart arteries in a procedure called PCI.
- Sometimes, it's hard to get the guidewire into the right place, so doctors might have to use a special method called antegrade dissection and reentry.
- This article talks about different tools, methods, and problems doctors face when using antegrade techniques for these complex blockages.
Tip Detection-Antegrade Dissection and Re-Entry With New Puncture Wire in CTO Intervention: Revolution Through 3D-Wiring.
JACC Asia
May 2024
Cardiovascular Center, Sakurabashi Watanabe Hospital, Osaka, Japan.
Article Synopsis
- The study introduced a new method called tip detection (TD) combined with a special wire (CP12ST) to enhance the effectiveness of treating chronic total occlusion (CTO) in coronary procedures.
- Researchers compared the success rates and procedural times of the TD method with an existing technique (Stingray) using a different wire (CP20) in 54 total cases.
- The findings showed that the TD method led to a significantly higher success rate (100% vs 67%) and shorter procedural times (145 minutes vs 185 minutes), with few complications in both groups.
Plaque characteristics associated with failure of primary balloon angioplasty for intracranial atherosclerotic stenosis: a retrospective study.

Neurology, Sun Yat-sen University First Affiliated Hospital, Guangzhou, Guangdong, China
Background: Primary balloon angioplasty (PBA) is an alternative treatment approach for intracranial atherosclerotic stenosis (ICAS); however, its efficacy may be compromised by arterial dissection or early elastic recoil after balloon dilation. This study aimed to explore the association between plaque characteristics on high-resolution magnetic resonance vessel wall imaging (HR-VWI) and failure of PBA for ICAS.
Methods: We conducted a retrospective analysis of 113 patients with ICAS who underwent HR-VWI before endovascular treatment.
