The BEnefit of LONGitudinal Micro-Incisions Prior to Paclitaxel-Coated Balloon Angioplasty (BELONG Study) in Patients With Lower Extremity Arterial Disease: Clinical Outcomes at 12 Months.

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).

Background And Purpose: The quantitative intra-arterial flow dynamics following percutaneous transluminal angioplasty and stenting (PTAS) for severe intracranial artery stenosis have never been investigated. We aimed to evaluate peritherapeutic intracranial artery flow dynamics following PTAS with quantitative magnetic resonance angiography (qMRA) to predict long-term stent patency.
Design: This is a prospective, single-center study.
The predictive factors for in-stent restenosis after interventional treatment of chronic carotid artery occlusion.
Acta Radiol
December 2024
Department of Interventional Radiology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, PR China.
Background: In-stent restenosis (ISR) is a potential severe complication that occurs in patients with severe carotid artery narrowing after carotid angioplasty and stent placement. However, this phenomenon has not been fully studied in the context of interventional treatment for chronic internal carotid artery occlusion (CICAO).
Purpose: To quantify the ISR rate and identify the risk factors leading to this event.
Intraprocedural and Delayed Plaque Protrusion in Carotid Artery Stenting Using a Dual-Layer Metallic Stent.

Department of Diagnostic and Interventional Radiology, Nara Medical University, Kashihara, Japan.
Background: Intravascular ultrasound-determined plaque protrusion (PP) during carotid artery stenting (CAS) using conventional stents is reported in 7.6% to 12% of cases and is associated with periprocedural cerebral embolism. The Casper/Roadsaver stent (CRS) is a dual-layer micromesh stent designed to reduce the risk of PP, with a mesh cell diameter 4-fold smaller size than that of conventional stents.

Department of Neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China
Background: In-stent restenosis (ISR) is the primary cause of stroke recurrence after intracranial stenting. Drug-eluting stents (DES) have recently shown great potential for reducing restenosis. This systematic review aimed to evaluate the efficacy and safety of DES compared with bare-metal stents (BMS) for intracranial atherosclerotic stenosis (ICAS).
