AIMS/HYPOTHESIS: Accelerated migration and proliferation of vascular smooth muscle cells (VSMCs) enhances arterial restenosis after angioplasty in insulin resistance and diabetes. Elevation of Src homology 2-containing protein tyrosine phosphatase 1 (SHP-1) induces apoptosis in the microvasculature. However, the role of SHP-1 in intimal hyperplasia and restenosis has not been clarified in insulin resistance and diabetes. METHODS: We used a femoral artery wire injury mouse model, rodent models with insulin resistance and diabetes, and patients with type 2 diabetes...

Nutcracker syndrome (NCS) is symptomatic unilateral renal venous hypertension due to compression of the left renal vein between the superior mesenteric artery and aorta (anterior NCS) or between the aorta and spine (posterior NCS). The left ovarian or spermatic vein empties into the left renal vein and is an additional site of venostasis in about half the cases of NCS. The presenting symptom of NCS in about half the cases is atypical left flank pain suggesting a disorder of the lower ribs or thoracolumbar spinal junction, particularly as the pain worsens with standing and increased lumbar lordosis...

En bloc pediatric transplantation (EBPT) began with the aim of increasing the donor pool due to the existing high demand for donors. At its inception, it was considered a type of suboptimal transplantation due to its association with a high incidence of vascular, urologic, and immunologic complications. The main objective of this study was to update information on EBPT with the largest case series that exists on a worldwide scale. In a retrospective study, the results obtained from brain-dead donors (BDDs; n = 770) were compared to those of EBPT (n = 100) from January 1990 to December 2012...

Percutaneous endovascular techniques are used increasingly in the vascular armamentarium. Commonly performed as day case procedures under local anaesthetic, they are suited to the highly co-morbid vascular patient population. Furthermore, technological advances have resulted in ever improving outcomes for aneurysmal and occlusive disease. Endovascular procedures such as endovascular aneurysm repair or iliac artery stenting are traditionally associated with reduced infectious complications compared to equivalent open techniques...

Chen Huang, Haijun Mei, Min Zhou, Xiaobing Zheng
A novel drug-eluting stent (DES) is required to target vascular smooth muscle cells (SMCs) without harming endothelial cells (ECs). Platelet-derived growth factor (PDGF) is critical for the proliferation and migration of SMCs. Sunitinib [a PDGF receptor (PDGFR) tyrosine kinase inhibitor]‑eluting stents may therefore inhibit neointimal formation. The aim of the present study was to examine the stent‑based delivery of sunitinib in a rabbit carotid model; in addition, the effects of sunitinib were evaluated in vitro...

Acute ischemic stroke (AIS) is the leading cause of premature mortality and morbidity worldwide for both men and women. Extracranial carotid artery stenosis/occlusion is responsible for approximately 11.5%% of ischemic strokes, whereas extracranial large vessel disease comprises roughly 16.6% of ischemic strokes. Carotid artery disease has been the source of significant debate among neurovascular and cardiovascular specialists, as well as vascular surgeons, as to the best method of revascularization, surgical reconstruction versus endovascular recanalization...

INTRODUCTION: Single stent deployment leads to a change in vascular geometry in wide necked bifurcation aneurysms. In some complex cases, the use of the single stent technique might not be sufficient or may not be feasible. The kissing-Y stenting technique appears to be an alternative endovascular treatment option. The aim of this study was to evaluate the effects of the kissing-Y stenting technique on vascular angular remodeling. METHODS: 21 patients with wide necked intracranial bifurcation aneurysms at different sites (10 anterior communicating artery, 6 middle cerebral artery, 3 basilar artery, 1 vertebral artery/posterior inferior cerebellar artery, 1 internal carotid artery/posterior communicating artery) were treated with 44 closed cell stents (follow-up 2012-2016) using the kissing-Y stenting technique...

AIMS: In the drug eluting stent (DES) era, patients with acute coronary syndrome (ACS) had a higher risk of early stent thrombosis compared with stable patients. The present study evaluated whether the same is true for the bioresorbable vascular scaffold (BVS: Abbott Vascular, Santa Clara CA). METHODS AND RESULTS: We assessed the relationship between the incidence of definite/probable scaffold thrombosis (ScT) (overall ScT and early ScT) and ACS percentage with the latest publications including the most recent large randomized controlled trials...

BACKGROUND: Drug-eluting stents (DES) have dramatically reduced restenosis rates compared to bare metal stents and are widely used in coronary artery angioplasty. The anti-proliferative nature of the drugs reduces smooth muscle cell (SMC) proliferation effectively, but unfortunately also negatively affects endothelialization of stent struts, necessitating prolonged dual anti-platelet therapy. Cell-type specific therapy may prevent this complication, giving rise to safer stents that do not require additional medication...

In-stent restenosis (ISR) is the most common long-term complication following Carotid Artery Stenting (CAS), affecting 3.5% to 21% of patients after a mean follow up of 18 months in published reports. Until now, the optimal management for ISR after CAS is still not clear and different endovascular treatments along with various surgical options have been proposed. Moreover, surgical treatment for ISR in a previously operated patient of ipsilateral endarterectomy is a technically demanding procedure. In this report, we describe a case of severe carotid recurrent ISR, which occurred after CAS for post-endarterectomy restenosis, that was successfully treated, in a straightforward way, with a carotid bypass using a Gore(®) Hybrid Vascular Graft...

Blunt subclavian artery injuries are rare and are associated with high morbidity and mortality. Several case reports have suggested that endovascular repair is safe with short operative times and minimal blood loss. We report a case of a 20-year-old male patient involved in a high speed motor vehicle collision that resulted in partial transection of left subclavian artery with complete luminal thrombosis. Patient also had a left main-stem bronchus avulsion along with major intra-abdominal injuries and multiple spine and long bone fractures...

OBJECTIVE: To detect an in-stent restenosis an invasive coronary angiography is commonly performed. Due to the risk associated to this procedure, a non-invasive method to detect or exclude an in-stent restenosis is desirable. The purpose of this study was to evaluate the influence of cardiac motion on stent lumen visibility in a third-generation dual-source CT scanner (SOMATOM Force, Siemens Healthcare, Forchheim, Germany), employing a pulsatile heart model (CoroSim by Mecora). METHODS: Thirteen coronary stents with a diameter of 3...

BACKGROUND: Optimal strut coverage and early vascular healing are important factors to reduce the risk of stent thrombosis. Data on early vascular healing with the new bioresorbable vascular scaffolds (BVS) are lacking. Further, healing response after BVS implantation in different clinical presentation has not been fully investigated. METHODS AND RESULTS: We assessed with optical coherence tomography (OCT) the early vascular response to BVS implantation in 26 consecutive patients presenting with acute coronary syndrome (ACS) or stable angina (SA)...
