This research investigated the mechanism of CLU in vascular restenosis by regulating vascular smooth muscle cell (VSMC) proliferation and migration. Firstly, rat models of balloon injury (BI) were established, followed by the assessment of the injury to the common carotid artery. The effect of CLU on the intimal hyperplasia of BI rats was measured after the intervention in CLU, in addition to the evaluation of proliferation, migration, and autophagy of VSMCs. Moreover, the interaction between ATG and LC3 was analyzed, followed by validation of the role of autophagy in CLU's regulation on the proliferation and migration of VSMCs. It was found that CLU was highly expressed in BI rats. Altogether, our findings indicated that CLU was highly expressed in vascular restenosis, and CLU over-expression promoted the binding between ATG3 and LC3, thus facilitating VSMC autophagy and eventually attenuating intimal hyperplasia and vascular restenosis.

Background And Rationale: In-stent restenosis (ISR) remains the leading cause of treatment failure following percutaneous coronary intervention (PCI) with contemporary drug-eluting stents. Especially in small caliber coronary arteries, restenosis is common following PCI and represents a treatment challenge. Drug-coated balloons (DCB) are an attractive alternative to stents for treatment of both ISR and small vessel disease.

Stenosis within the arteriovenous fistula (AVF) of hemodialysis patients leads to vascular access dysfunction and inadequate hemodialysis. Percutaneous transluminal angioplasty (PTA) is the standard therapy for stenosis. However, rates of restenosis and loss of access patency remain high.

Arterial diseases (ADs) are a significant health problem, with high mortality and morbidity rates. Endovascular interventions, such as balloon angioplasty (BA), bare-metal stents (BMSs), drug-eluting stents (DESs) and drug-coated balloons (DCBs), have made significant progress in their treatments. However, the issue has not been fully resolved, with restenosis remaining a major concern.

Introduction: Carotid artery stenosis is a significant contributor to ischemic strokes, and its surgical management includes carotid artery endarterectomy (CEA), transfemoral carotid artery stenting (TF-CAS), and trans carotid artery revascularization (TCAR). CEA has traditionally been preferred, but TF-CAS and TCAR are also excellent alternative options if the anatomy of the vessels allows them. This study reports our short- and mid-term outcomes after carotid artery revascularization in symptomatic patients at a stroke center.

Objective: In this study, we aimed to retrospectively review patients with post-thrombotic syndrome (PTS) and investigate its long-term outcomes, and a novel classification were presented across multiple institutions.
Methods: We retrospectively evaluated patients with PTS who underwent endovascular therapy at two institutions between January 2018 and September 2023. Baseline patient demographics, lesion characteristics, and in-hospital and follow-up outcomes were collected and analyzed retrospectively.
