A retrospective analysis of the results of endovascular operations on the arteries of the lower extremities was performed in 209 patients, of which 45 (21.5%) were patients with chronic ischemia of the 2nd stage, category 4, 138 (66.1%) of patients with ischemia of the lower extremities of the third stag, category 5 and 26 (12.4%) of patients with IV stage, category 6 (by classification Rutherford et al., 1997) 17, 187 men, 22 women. The average age of patients was 63.7±9.3 years. Based on clinical and angiographic data, several variants of endovascular revascularization of the lower extremities were used: the vasoballoone segmentation followed by its stenting with a self-expanding stent of Terumo Misago (Japan) or a stent of Palmas Cordis (USA), one stent or two end-to-end stents (the stenting of the artery was supplemented by vasoballoone dilatation of the segment over the stents, between stents or under stents), sub intimal angioplasty was performed under the condition of Re-Entry Outback (Cordis, USA), balloon angioplasty was used using IN cylinders...

Patients with below-the-knee arterial disease are primarily individuals suffering from critical limb ischemia (CLI), while a large percentage of these patients are also suffering from diabetes or chronic renal failure or both. Available data from randomized controlled trials and their meta-analysis demonstrated that the use of infrapopliteal drug-eluting stents (DES), in short- to medium- length lesions, obtains significantly better results compared to plain balloon angioplasty and bare metal stenting with regards to vascular restenosis, target lesion revascularization, wound healing and amputations...

Restenosis is a major problem after percutaneous coronary intervention (PCI) treatment. Inflammation is one of the major core mechanisms involved in the occurrence of restenosis, and plays an important role in intimal hyperplasia. Detoxification and activating blood circulation decoction (DABCD) is a traditional Chinese medicine that is used in the treatment and prevention of atherosclerotic and inflammatory diseases. Our previous studies demonstrated that DABCD-mediated cardioprotection involves anti-inflammatory mechanisms and could be developed as a novel drug for the treatment of vascular smooth muscle cell (VSMC) proliferation and aortic restenosis...

Although rapamycin is a well-known conformational inhibitor of mTORC1, it is now widely used for treating arterial restenosis. Various rapamycin analogues (rapalogue) have been made for applying to drug-eluting stents. Here we show that two major rapalogues, everolimus and biolimus, exert a differential effect on the mTORC1-mediated signaling pathways in vascular smooth muscle cells. In balloon-injured carotid arteries, both rapalogues strongly inhibit neointimal hyperplasia. Signaling pathway analyses reveal that everolimus exert cytotoxicity by increasing cellular reactive oxygen species and consequently reduce energy metabolism...

RATIONALE: The safety and efficacy of drug-coated balloon (DCB) technology have primarily been proven in the treatment of coronary in-stent restenosis. Whereas increasing evidences show that DCB use was feasible in certain de novo coronary lesions. In 2012, Vassilev reported the 1st case in which a coronary aneurysm formed after a DCB was used to treat drug-eluting stent (DES) restenosis. To date, limited information has been reported on coronary artery aneurysm (CAA) development following DCB treatment of de novo lesions...

Natural products are used widely for preventing intimal hyperplasia (IH), a common cardiovascular disease. Four different cells initiate and progress IH, namely, vascular smooth muscle, adventitial and endothelial cells, and circulation or bone marrow-derived cells. Vascular smooth muscle cells (VSMCs) play a critical role in initiation and development of intimal thickening and formation of neointimal hyperplasia. In this review, we describe the different originating cells involved in vascular IH and emphasize the effect of different natural products on inhibiting abnormal cellular functions, such as VSMC proliferation and migration...

Background We have reported that cytochrome P450 1B1 ( CYP 1B1), expressed in cardiovascular tissues, contributes to angiotensin II -induced vascular smooth muscle cell ( VSMC ) migration and proliferation and development of hypertension in various experimental animal models via generation of reactive oxygen species. This study was conducted to determine the contribution of CYP 1B1 to platelet-derived growth factor-BB-induced VSMC migration and proliferation in vitro and to neointimal growth in vivo. Methods and Results VSMC s isolated from aortas of male Cyp1b1 +/+ and Cyp1b1 -/- mice were used for in vitro experiments...

Percutaneous coronary intervention (PCI) is main treatment for acute coronary syndrome (ACS). However, restenosis caused by PCI-induced injury influences the outcome of patients. Linagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, has been reported to ameliorate intimal hyperplasia post vascular injury. The underlying mechanisms by which linagliptin protects against balloon injury are unclear and require to be explored. Herein, Wistar rats with carotid artery balloon injury were given 1, 2 or 3 mg/kg/day linagliprin for 6 weeks...

Vascular smooth muscle cells (VSMCs) and endothelial cells (ECs) are crucial in vascular remodeling. They exert pivotal roles in the development and progression of atherosclerosis, vascular response to injury, and restenosis after transcatheter angioplasty. As a witness of their importance in the cardiovascular system, a large body of evidence has accumulated about the role played by micro RNAs (miRNA) in modulating both VSMCs and ECs. More recently, a growing number of long noncoding RNA (lncRNAs) came beneath the spotlights in this research field...

Bioresorbable scaffolds have emerged as a potential alternative to non-erodible metal implants to alleviate the long-term risk of permanent device vascular implant-related adverse events. Bioresorbable scaffolds provide a temporary mechanical support function until the vessel reaches complete healing, and the implant progressively disappears and vasomotion resumes. A polymer matrix with embedded drugs coated onto the scaffold surface degrades slowly, reducing the size from the exterior toward the interior, and this allows controlled drug release to a local vascular segment...

Background: The role of stenting for intracranial arterial stenosis (ICAS) has been increasingly debated due to negative results of randomized trials. Thus, exploration of more appropriate devices may hopefully shed light on the endovascular approach, especially for patients with recalcitrant ICAS related to a high risk of stroke. We sought to present and analyze the data of Neuroform EZ stenting for medically refractory ICAS in a single-center series. Materials and methods: Between November 2016 and January 2018, 45 consecutive patients treated with the Neuroform EZ stent were included in our retrospective study...

Coronary artery stenting following balloon angioplasty represents the gold standard in revascularization of coronary artery stenoses. However, stent deployment as well as percutaneous transluminal coronary angioplasty (PTCA) alone causes severe injury of vascular endothelium. The damaged endothelium is intrinsically repaired by locally derived endothelial cells and by circulating endothelial progenitor cells from the blood, leading to re-population of the denuded regions within several weeks to months. However, the process of re-endothelialization is often incomplete or dysfunctional, promoting in-stent thrombosis and restenosis...

PURPOSE OF REVIEW: This review will focus on our approach for the treatment of refractory in-stent restenosis. RECENT FINDINGS: The discovery of bare metal stents over three decades ago set a milestone in the evolution of percutaneous coronary intervention, which is currently the most widely performed procedure for the treatment of symptomatic coronary disease. However, the broad utilization of stents resulted in the new phenomenon of in-stent restenosis (ISR). Over the years, there has been an increase of the incidence of ISR despite continued improvement of drug-eluting stent (DES) technology...

Angiogenesis, the process of new blood vessel formation from pre-existing ones, plays a key role in various physiological and pathological conditions. Alteration of the angiogenic balance, consequent to the deranged production of angiogenic growth factors and/or natural angiogenic inhibitors, is responsible for angiogenesis-dependent diseases, including cancer. Fibroblast growth factor-2 (FGF2) represents the prototypic member of the FGF family, able to induce a complex "angiogenic phenotype" in endothelial cells in vitro and a potent neovascular response in vivo as the consequence of a tight cross talk between pro-inflammatory and angiogenic signals...

Introduction: Preservation of structural integrity of the endothelial monolayer and maintenance of endothelial cell function are of critical importance in preventing arterial thrombosis, restenosis and atherosclerosis. Obesity has been intimately linked with endothelial dysfunction, and reports of reduced abundance and functional impairment of circulating progenitor cells in obesity have led to the suggestion that defective endothelial repair contributes to obesity-related cardiovascular disease...
