AI Article Synopsis
Article Abstract
One of the rarest lesions is in-stent restenosis chronic total occlusion (CTO). Limited data suggest that the treatment success rate is dependent on the possibility to cross into the lumen of an occluded stent, and the decision about what technique to use varies by operator preference. The knuckle technique is used to create a deliberate dissection plane in various CTO techniques. A guide wire is pushed until a complex loop is formed and advanced through the lesion. In this report we present a case where a knuckle wire guided by intravascular ultrasound control is used to penetrate the distal cap in an in-stent restenosis CTO lesion.

Purpose: Angioplasty of lower extremity arteries with calcification may result in flow-limiting dissection requiring bail-out stenting with unfavorable long-term outcomes. Vessel preparation prior to angioplasty may improve immediate results of the angioplasty and long-term patency. This prospective study assessed the 12-month outcomes of patients who underwent novel vessel preparation catheter, the FLEX Vessel Prep™ System (FLEX VP), prior to drug-coated balloon angioplasty (DCB-PTA).

In-stent restenosis (ISR) following interventional therapy is a fatal clinical complication. Current evidence indicates that neointimal hyperplasia driven by uncontrolled proliferation of vascular smooth muscle cells (VSMC) is a major cause of restenosis. This implies that inhibiting VSMC proliferation may be an attractive approach for preventing in-stent restenosis.

This study aims to identify in vivo predictors for focal restenosis in patients with in-stent restenosis (ISR). Methods: The study recruited patients with ISR who underwent OCT examination in the Cardiology Department of the Affiliated Hospital of Zunyi Medical University from October 2018 to December 2022.

The present study was aimed to investigate whether Gensini score or SYNTAX score was a valuable tool to predict in-stent restenosis (ISR) in coronary artery disease (CAD) patients with drug-eluting stents (DES) implantation. A retrospective case-control study and a validating retrospective cohort study were designed. All subjects' information was collected from the First Affiliated Hospital of Xinjiang Medical University.
