AI Article Synopsis
- The study highlights the potential link between coronary stent fractures and complications like restenosis and thrombosis.
- A case involving a 43-year-old man revealed significant fractures in a sirolimus-eluting stent (SES) after he received a paclitaxel-eluting stent (PES).
- The use of microcomputed tomography (micro-CT) demonstrated detailed, nondestructive imaging, showing that the most severe stent fractures coincided with areas of significant luminal narrowing.
Article Abstract
Unlabelled: Coronary stent fracture has been postulated as an important mechanism for in-stent restenosis and late-stent thrombosis. We have developed a nondestructive microcomputed tomography (micro-CT) technique to image en bloc stented arterial segments.
Case Report: A 43-year-old man died of sepsis 5 months following placement of a paclitaxel-eluting stent (PES) in the left circumflex coronary artery to treat in-stent restenosis of a sirolimus-eluting stent (SES). Micro-CT three-dimensional images of the overlapping stents were notable for numerous connecting element fractures along the length of the SES. No fractures were observed in the PES. The greatest area of luminal narrowing is related to the region of most extensive stent fracture. Micro-CT of en bloc specimens provides high resolution (16 μm), three-dimensional images allowing for visualization of the stented arterial segment in a nondestructive manner.

Enhanced Efficiency of Sequential Cutting Balloon Angioplasty in Calcified Coronary Artery Disease: The RODIN-CUT Technique.
Catheter Cardiovasc Interv

HartCentrum Ziekenhuis Aan de Stroom (ZAS) Middelheim, Antwerp, Belgium.
Article Synopsis
- Heavily calcified coronary artery disease complicates percutaneous coronary intervention (PCI), requiring advanced techniques like cutting balloons (CB), which need standardization for better effectiveness.
- The study presents the RODIN-CUT technique, which involves sequential CB inflations guided by intravascular ultrasound (IVUS) to improve plaque modification and stent expansion in difficult cases.
- Results indicate that RODIN-CUT achieved high procedural success rates and minimal complications, suggesting it could be a simple and cost-effective method for treating calcified lesions, though larger studies are needed to confirm its validity.
Repeated Supera stent fracture following stenting for popliteal artery occlusion: a case report.

The popliteal artery segment is particularly challenging for endovascular treatment. Stents used for treating popliteal artery lesions are usually associated with an increased risk of stent fracture and re-occlusion. The Supera stent is designed to withstand mechanical stress, with a low risk of fracture.

Urethrovaginal fistulas are rare complications often arising from urethrovaginal injuries commonly due to obstetrical trauma, urethral surgeries, pelvic fractures, or neoplastic treatments. Here, we present a unique case involving a 23-year-old female patient with a large urethrovaginal fistula and complete anterior vaginal wall sloughing following prolonged obstructed labor. Nine months post-cesarean, she reported urine leakage via the vagina upon catheter removal, which intensified in an erect posture.

Institute for Vascular Research, St. Franziskus Hospital, Münster, Germany.
Background: To compare the performance of a new-generation cobalt-chromium balloon-expandable bare metal stent with a stainless steel platform for the treatment of iliac occlusive disease.
Methods: Consecutive patients treated for symptomatic iliac occlusive disease between 2014 and 2021 with the cobalt-chromium Dynetic-35 or the stainless steel Dynamic platform were retrospectively evaluated. Outcome measures included technical success, device- or procedure-related death, clinically-driven target lesion revascularization (CD-TLR), primary patency, and major index limb amputation up to 12 months.
