Coronary aneurysm is a rare complication after coronary excimer laser angioplasty. A 45-year-old woman underwent laser angioplasty and bare metal direct stenting of the proximal segment of the left anterior descending artery (LAD); after 3 months, angiographic follow-up showed significant ostial stenosis of the LAD with a large sacciform aneurysm and diffuse intrastent restenosis.

Guidewire entrapment (GE) is a rare complication that warrants complex interventions or surgical procedures. Here, we report the removal of an entrapped guidewire using excimer laser coronary angioplasty (ELCA) in a case of chronic total occlusion (CTO). Plaque tissue trapped with the guidewire was also removed.

To retrospectivly investigate the short-term clinical outcomes of one-stop and two-staged endovenous laser ablation (EVLA) procedures for treatment of varicose veins (VVs) and iliac vein compression syndrome (IVCS). In this study, 424 patients were treated for VVs and IVCS from June 2017 to June 2020, 91 underwent one-stop stent angioplasty (SA) and EVLA, 132 underwent two-staged SA and EVLA, 104 underwent one-stop balloon angioplasty (BA) and EVLA, and 97 underwent two-staged BA and EVLA. Clinical outcomes and complications were recorded at 3 and 12 months post-intervention.

Excimer laser coronary angioplasty (ELCA) in percutaneous coronary intervention (PCI) is safe and effective. However, thrombotic complications after ELCA occasionally occur. This study aimed to evaluate the impact of lipid-rich plaque in both in-stent restenosis (ISR) and de novo lesions on thrombus formation and transient no-reflow after ELCA.

Article Synopsis
- Managing chronic total occlusions (CTOs) in coronary artery disease is challenging, particularly when standard techniques don't work on lesions that are difficult to cross.
- A 62-year-old male patient with exertional chest pain had multiple conventional treatments fail to address a CTO in his right coronary artery, highlighting the difficulty of these types of lesions.
- The use of orbital atherectomy with the DiamondBack 360 system finally allowed successful treatment by crossing the CTO, showcasing its potential as a valuable option for complex cases where traditional methods have failed.

Article Synopsis
- Percutaneous coronary intervention (PCI) has greatly improved treatments for coronary artery disease, but in-stent restenosis (ISR) remains a significant issue, especially when complicated by calcification.
- Various techniques exist for treating calcified ISR, including super-high-pressure balloon dilation, atherectomy methods, and intravascular lithotripsy (IVL).
- This case report discusses a patient with severe, calcified ISR in a large artery, showcasing the use of shockwave lithotripsy combined with balloon dilation to improve stent expansion, highlighting the effectiveness of innovative approaches for difficult ISR cases.
