Percutaneous revascularization of superficial femoral artery (SFA) is increasingly carried out to treat patients with peripheral vascular disease and either intermittent claudication or critical limb ischemia. Transradial vascular access is increasingly adopted for invasive procedures due to reduced access-site complications and improved patient's comfort, compared with transfemoral. However, compared with ...

Ductal stenting for pulmonary blood supply in newborns with cyanotic congenital heart disease (CHD) might be a low risk and safe alternative to the surgical aorto-to-pulmonary artery (AP) shunt in dual-source lung perfusion. Ductal stenting in truly duct-dependent pulmonary circulation has not been evaluated. Prospective interventional and clinical follow-up trial. ...

The treatment of atherosclerotic plaques near and involving coronary bifurcations is especially challenging for interventional procedures. Optimization of these treatment strategies should begin with an understanding of how disease came to be localized to these regions, followed by careful design of the interventional tools and implanted devices. This manuscript reviews ...

One of the technical limitations of surgeon-modified fenestrated stent grafts is the lack of a diameter-reducing wire, which facilitates catheterization of target branches if there are errors of device design, alignment, or implantation. This article describes a technique of adding a diameter-reducing wire to the modified TX2 fenestrated stent graft ...

A 73-year-old male patient was found to have an abdominal aortic aneurysm complicated with bilateral common iliac artery aneurysms. He also had hepatitis C, chronic liver cirrhosis (Child-Pugh class B), a rupture of esophageal varices, hepatocellular carcinoma, and intractable ascites. The functions of other systemic organs were also impaired. We ...

A 62-year-old diabetic female was referred to our institution with a 6-month history of pulmonary hypertension and worsening right-sided heart failure. Computed tomography of the chest and pulmonary angiogram revealed a pulmonary artery mass. Due to patient's frail state, palliative kissing stenting to both pulmonary arteries was performed with optimal ...
Santoro Giuseppe - - 2010
Despite current trends toward primary repair, surgical systemic-to-pulmonary shunt is still an invaluable palliative option in some patients with congenital heart defects and duct-dependent pulmonary circulation. However, arterial duct stabilization with a high-flexibility coronary stent could be an effective alternative in high-risk surgical candidates or whenever short-term pulmonary blood flow ...

Aortic surgery involving major aortic branches (supraaortic trunks, visceral, renal arteries, and iliac arteries) is complicated by the requirement to dissect and occlude them during revascularization. We report an 8-year experience with a sutureless telescoping anastomotic technique to revascularize these branches with minimal branch dissection and organ ischemia. Over an ...

Endovascular stents are commonly used to manage arterial diseases such as Aortic Abdominal Aneurysm (AAA), aortic dissection and coarctation. The radial force the stent applies to the vessel must be large enough to resist stent migration, but not so large that the mechanical stimulus initiates adverse vessel remodeling. We employed ...

In a non-injured porcine coronary artery model, the aim was to evaluate vascular compatibility of the novel platinum chromium everolimus-eluting PROMUS Element stent as compared to the following control stents: everolimus-eluting PROMUS (XIENCE V), bare metal Element, and polymer-only Element. Stent pairs (n=228) evenly distributed among the four stent types ...

The use of self expandable metallic stents (SEMS) in the palliation of dysphagia due to malignant esophageal stenosis is a gold standard. Covered stents are used in all cases with overt air-digestive fistula or high potential for fistula development. The procedure is associated with a low incidence of procedure-related complications. ...
