A 79-year-old male who had a history of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) received coronary angiography (CAG), because of angina pectoris. CAG showed in-stent restenosis of the paclitaxel-eluting stent (PES). Since the devices could not pass the lesion, we performed rotational atherectomy. Although we could not identify the calcified lesion by the optical frequency domain imaging (OFDI) findings because of strong attenuation, the intravascular ultrasound (IVUS) image showed the superficial calcification...

Objectives This study evaluates the effect of stent sizing with CT-scan on the incidence of restenosis in peripheral arterial disease. Methods This retrospective study included 59 patients with 66 arterial lesions who underwent a endovascular procedure for peripheral arterial disease between April 2013 and October 2013. All patients had de novo iliac or femoral lesions, were candidates for an endovascular procedure alone and underwent CTA preoperatively. The stent actually implanted, whose dimensions were chosen on the basis of the operator's experience on an intraoperative 2D angiography, was compared to the "ideal" stent chosen retrospectively on the basis of precise lesion sizing by the preoperative CTA...

MiR-206 has been found to play a critical role in skeletal muscle proliferation, differentiation and regeneration. However, little is known about the function of miR-206 in vascular smooth muscle cells (VSMCs) biology. In this study, we will investigate its roles in phenotypic switching of VSMCs and neointimal lesion formation. First, we identified the expression of miR-206 in VSMCs treated with various concentrations of TGFβ1 and in rat carotid arteries after angioplasty by using qPCR. TGFβ1 inhibited the expression of miR-206 and TGFβ1 inhibitor induced miR-206 expression...

Stenting has long been used in the paranasal sinuses with the goals of maintaining a patent sinus cavity during the postoperative healing process and preventing restenosis from inflammation or scarring. More recently, drug-eluting stents have been introduced. Steroid-impregnated dressings and implants appear to be safe, although likely have increased systemic absorption compared with topical nasal steroid sprays and rinses. There is evidence to support the use of steroid-releasing implants in the ethmoid cavity in the postoperative period; however, more study is needed to truly define the role of these implants...

Atherosclerotic renal artery stenosis is the leading cause of secondary hypertension; it can also cause progressive renal insufficiency and cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid lowering agents, and antiplatelet therapy is the first line of treatment in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe renal artery stenosis are likely to benefit from renal artery revascularization...

Neointimal hyperplasia is the primary lesion underlying atherosclerosis and restenosis after coronary intervention. We previously described the essential angiogenic function of the adrenomedullin (AM)-receptor activity-modifying protein 2 (RAMP2) system. In the present study, we assessed the vasoprotective actions of the endogenous AM-RAMP2 system using a wire-induced vascular injury model. We found that neointima formation and vascular smooth muscle cell proliferation were enhanced in RAMP2+/- male mice. The injured vessels from RAMP2+/- mice showed greater macrophage infiltration, inflammatory cytokine expression and oxidative stress than vessels from wild-type mice, and less re-endothelialization...

PURPOSE: This retrospective study evaluated the long-term results of endovascular repair in the management of arterial stenosis caused by Takayasu's arteritis (TA). METHODS: Sixty-seven endovascular procedures (percutaneous transluminal balloon angioplasty or stenting) were performed for 49 arterial lesions in 35 patients. Endovascular treatment was performed when the disease was inactive. The patients were pretreated with immunosuppressive drugs and followed every 3∼6 months to monitor disease activity and medical treatment...

Both the use of drug-eluting stents and drug-coated balloons have mitigated the prevalence of in-stent restenosis, but in-stent remains a problem that continues to affect the long-term outcomes of femoro-popliteal endovascular therapy. This paper will provide an overview on the latest data with regard to the treatment of femoro-popliteal in-stent restenosis.

Coronary artery aneurysm following drug-eluting stent implantation is rare in the literature. The presentation combined a life-threatening condition with severe in-stent restenosis. How to treat this condition is a complex problem because a surgical approach for a proximal left circumflex lesion is difficult. A hybrid method that is a combination of coronary bypass surgery and coronary stenting for left main bifurcation in-stent restenosis and proximal coronary artery aneurysm is a feasible strategy.

AIMS: In-stent restenosis (ISR) is an important cause of DES failure and target vessel revascularization. We evaluated differences between early and late-presenting restenosis in second-generation drug-eluting stents (DES) using optical coherence tomography (OCT). METHODS AND RESULTS: Overall, 171 cases of second-generation DES ISR with a follow-up OCT minimum lumen area <3.0mm2 were included; 33.3% of patients (n=57) had early ISR; and 67.7% (n=114) had late ISR (duration from stent implantation >1 year)...

INTRODUCTION: Percutaneous balloon aortic valvuloplasty (BAV) has been limited by the risk of complications and restenosis. However, growing use of transcatheter aortic valve implantation (TAVI) has revived interest in this technique. We analyzed the current indications for BAV and outcomes in a single center. METHODS: Acute results and long-term outcomes were analyzed in a retrospective single-center registry of patients undergoing BAV between January 2013 and January 2016...

Wegener's granulomatosis is a necrotizing granulomatous vasculitis of autoimmune origin that primarily affects the upper and lower airways and kidneys. It is very rare in children and adolescents. When started at a young age it is often associated with subglottic stenosis. Subglottic stenosis is a potentially fatal manifestation of Wegener's granulomatosis. Its diagnosis requires a high index of suspicion since it might develop in the absence of other signs of activity. Occasionally, subglottic stenosis may present as the initial manifestation of the disease...

OBJECTIVES: To evaluate the safety and feasibility of subclavian artery stenting for coronary-subclavian steal syndrome (CSSS). BACKGROUND: CSSS is a rare cause of myocardial ischemia due to ipsilateral subclavian artery stenosis in patients who have undergone coronary artery bypass graft. However, current knowledge of the optimal therapy for CSSS is limited. METHODS: The clinical data of 37 patients (33 male; mean age 65 ± 6 years) with CSSS who had undergone subclavian artery stenting between April 2007 and December 2015 were analyzed...

Background The instantaneous wave-free ratio (iFR) is an index used to assess the severity of coronary-artery stenosis. The index has been tested against fractional flow reserve (FFR) in small trials, and the two measures have been found to have similar diagnostic accuracy. However, studies of clinical outcomes associated with the use of iFR are lacking. We aimed to evaluate whether iFR is noninferior to FFR with respect to the rate of subsequent major adverse cardiac events. Methods We conducted a multicenter, randomized, controlled, open-label clinical trial using the Swedish Coronary Angiography and Angioplasty Registry for enrollment...

Two different stent configurations (i.e. the well known Palmaz-Schatz (PS) and a new stent configuration) are mechanically investigated. A finite element model was used to study the two geometries under combining loads and a computational fluid dynamic model based on fluid structure interaction was developed investigating the plaque and the artery wall reactions in a stented arterial segment. These models determine the stress and displacement fields of the two stents under internal pressure conditions. Results suggested that stent designs cause alterations in vascular anatomy that adversely affect arterial stress distributions within the wall, which have impact in the vessel responses such as the restenosis...

BACKGROUND: Due to the inherent limitations of current generation BVSs, complex coronary artery disease often contains BVS unsuitable segments. Our aim was to assess the feasibility of a hybrid approach using bioresorbable vascular scaffolds (BVSs) and drug-eluting stents (DESs) for the treatment of complex coronary artery lesions not suitable for a scaffolding only approach. METHODS: A retrospective multicenter cohort analysis was performed on patients with complex de novo or in-stent restenosis lesions treated with a hybrid BVS (Absorb BVS, Abbott Vascular, Santa Clara, CA) and DES strategy...

We have performed stenting in 11 patients with symptomatic vertebral arterial orifice stenosis refractory to medical treatment or impairment in anterior circulation. Three of the 11 patients experienced asymptomatic severe in-stent restenosis or occlusion. Bare metal stents were used in those three patients, two of whom received revascularization therapy. Development of sufficient cervical collateral channels reconstituting the distal vertebral artery was the common feature in patients with asymptomatic in-stent restenosis...
