BACKGROUND: There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety of BVS implantation for the treatment of CTO. METHODS AND RESULTS: We retrospectively evaluated CTO cases treated with BVS from a multicenter registry. The primary end point was target lesion failure defined as a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization...

: Small-diameter synthetic vascular grafts have high failure rate due to primarily surface thrombogenicity, and effective surface chemical modification is critical to maintain the patency of the grafts. In this study, we engineered a small-diameter, elastic synthetic vascular graft with off-the-shelf availability and anti-thrombogenic activity. Polycarbonate-urethane (PCU), was electrospun to produce nanofibrous grafts that closely mimicked a native blood vessel in terms of structural and mechanical strength...

Seung Kwon Kim, Bryan G Belikoff, Carlos J Guevara, Seong Jin Park
We propose an algorithm for management after transjugular intrahepatic portosystemic shunt (TIPS) placement according to clinical manifestations. For patients with an initial good clinical response, surveillance Doppler ultrasound is recommended to detect stenosis or occlusion. A TIPS revision can be performed using basic or advanced techniques to treat stenosis or occlusion. In patients with an initial poor clinical response, a TIPS venogram with pressure measurements should be performed to assess shunt patency...

Endovascular surgery represents a minimally invasive procedure for the treatment of occlusive and aneurysmal arterial disease. However, it is followed by inflammatory response, with a rise in specific inflammatory biomarkers, such as C-reactive protein, serum amyloid A and fibrinogen. Shear stress during balloon inflation and vascular injury represents triggering events for the inflammatory process, stimulating the production of proinflammatory molecules and activation of circulating monocytes. The current literature indicates that stent implantation induces more prominent inflammatory reaction...

BACKGROUND: The incidence of contrast-induced acute kidney injury is strongly related to the amount of the given contrast. Our objectives were to evaluate the efficacy and safety of coronary sinus aspiration (CSA) procedure to reduce the volume of the given contrast and attenuate the risk of contrast-induced acute kidney injury. METHODS AND RESULTS: The study included 43 patients with type 2 diabetes mellitus and renal impairment (creatinine 1.5-3 mg/dL) who were candidates for coronary angiography...

Iatrogenic femoral artery pseudoaneurysm at the level of the hip joint in a 52-year-old patient was treated by ultrasound-guided percutaneous thrombin injection, while a balloon was inflated at the neck of the pseudoaneurysm under fluoroscopy, to prevent thrombin leakage to the arterial system.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has received increasing attention for critically uncontrolled hemorrhagic shock. However, the efficacy of REBOA in patients in youth is unknown. OBJECTIVES: The aim of this study was to evaluate the mortality and characteristics of patients of age ≤ 18 years with severe traumatic injury who received REBOA. METHODS: We retrospectively analyzed observational cohort data from the Japan Trauma Data Bank (JTDB) from 2004 to 2015...

OBJECTIVES: To study the long-term outcomes of rotational atherectomy (RA) for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: There is little evidence on the incidence, procedural results and long-term outcomes of RA for CTO PCI. METHODS: This registry included data from consecutive patients undergoing CTO PCI at four specialized centers. Major adverse cardiac events (MACE: cardiac death, target-vessel myocardial infarction and ischemia-driven target-vessel revascularization) on follow-up were the primary endpoint...

Treatment of complex aneurysms using microsurgical and other conventional neuroendovascular techniques remains challenging. As a result, stent- and balloon-assisted coiling are instead performed to treat morphologically complex aneurysms, which include giant, wide-necked, and fusiform aneurysms. While these techniques have had success in treating these complex aneurysms, recanalization rates associated with these techniques are still problematic. In the constant effort to improve the outcome of complex aneurysm treatment, flow-diverting stents (FDSs) have emerged in recent years as the preferred treatment...

An 81-year-old male with severe symptomatic aortic stenosis with ventricular tachycardia was referred for treatment. Balloon aortic valvuloplasty was performed under cardiopulmonary resuscitation. Though transcatheter aortic valve implantation (TAVI) was considered high risk for annulus rupture and aortic regurgitation due to annular calcification, TAVI was performed because of extremely high surgical risk. Moderate-to-severe aortic regurgitation (AR) remained and progression of acidosis could not be managed with continuous hemodiafiltration...

INTRODUCTION/PURPOSE: Flow diversion has allowed cerebrovascular neurosurgeons and neurointerventionalists to treat complex, large aneurysms, previously treated with trapping, bypass, and/or parent vessel sacrifice. However, a minority of aneurysms remain that cannot be treated endovascularly, and microsurgical treatment is too dangerous. However, balloon test occlusion (macro and micro), micro WADA testing, ICG, intra-angiography and intra-operative monitoring are all available to clinically test the hypothesis that vessel sacrifice is safe...

BACKGROUND: A strategy of rehabilitation for pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries (PA/VSD/MAPCAs) comprises repetitive shunting and patching procedures of the central pulmonary arteries. We wanted to determine the feasibility and limitations of a strategy of rehabilitation. METHODS: The outcomes of 37 consecutive patients operated from June 2003 to December 2014 for PA/VSD/MAPCAs were reviewed. The patients were directed to a rehabilitation strategy, except when they presented in heart failure with very large collaterals...

Bleeding gastric varices (GV) are managed by cyanoacrylate glue injection with transjugular intrahepatic portosystemic shunt (TIPSS) as modality for treatment failure. Ulcer can form at the site of glue injection over GV and it can cause bleeding. Treatment approach for such bleed is not well described. Balloon-occluded retrograde transvenous obliteration (BRTO), TIPSS, and devascularization remain the treatment options in this scenario. BRTO is an endovascular procedure where a balloon catheter is inserted into a draining vein of GV, and the sclerosant can be injected into the varices through the catheter during balloon occlusion...
