while blunt trauma of the head and neck are a common pattern of injury, significant problems related to the prompt diagnosis and optimal management of traumatic artery injuries have been reported in the literature. while patients with major artery injuries might develop hemorrhagic shock very rapidly, patients with blunt cerebrovascular injuries (bcvi) can present asymptomatic, but complication...

BACKGROUND/AIMS Although complex bifurcation stenting in patients with non-left main (LM) bifurcation lesions has not yielded better clinical outcomes than simpler procedures, the utility of complex bifurcation stenting to treat LM bifurcation lesions has not yet been adequately explored. METHODS In the present study, patients who underwent LM-to-left anterior descending (LAD) coronary artery...

1093 November 2014 W ITH the advent of percutaneous coronary intervention (PCI), specifically the bare-metal stent (BMS) and subsequently, the drug-eluting stent (DES), the role of interventional cardiology in coronary revascularization has greatly increased.1 An estimated 600,000 coronary artery stents are placed annually in the United States for the management of acute and chronic coronary ar...

There are no reported cases of a pseudoaneurysm leading to a fistula into the pulmonary artery after percutaneous coronary intervention. We describe a patient who developed a late pseudoaneurysm after left main trunk (LMT) stenting with paclitaxel-eluting stent, discovered during coronary angiography. Transesophageal echocardiography and contrast-enhanced computed tomographic scan revealed a pe...

Early and late modifications of stenosis geometry after stenting of coronary arteries were assessed. Morphologic changes were evaluated by quantitative coronary angiography (automated edge-detection) and theoretical pressure drop across the dilated and stented stenosis was calculated from the Poiseuille formula, with turbulent resistances assuming a coronary blood flow of 1 or 3 ml/s. Eleven pa...

Coronary artery disease is the most important cause of mortality in patients with systemic lupus erythematous (SLE). After stenting for coronary artery disease in SLE patients similar to non-SLE patients, the risk of stent thrombosis is always present. Although there are reports of stent thrombosis in SLE patients, very late recurrent stent thrombosis is rare. We experienced a case of very late...

BACKGROUND The aim of this study was to summarize our single-center real-world experience with percutaneous coronary intervention (PCI) stenting of unprotected left main coronary artery (ULMCA). PCI-stenting of the ULMCA, while controversial, is emerging as an alternative to coronary artery bypass graft (CABG) surgery in select patients and clinical situations. METHODS Between January 2005 an...

Coronary stents reduce the rates of abrupt closure, emergency coronary artery bypass graft surgery and restenosis, but do not prevent myocardial infarction or death at six months. The financial burden of increased stent use and the difficulty in managing in-stent restenosis have provided the impetus to develop provisional stenting strategies. Patients at low risk for restenosis after balloon an...

Safety and efficacy concerns regarding elective coronary artery surgery in patients with prior coronary stents Recent data have raised concerns about the safety of drug-eluting stents. 1 Stents are used in over 70% of percutaneous coronary interventions (PCIs) because they reduce the risk of acute major complications of PCI and long-term restenosis. Despite the low procedural morbidity afforded...

INTRODUCTION Approximately 15 to 30% of patients undergoing percutaneous coronary intervention (PCI) will require repeated revascularization. There is an ongoing debate concerning the impact of prior PCI on subsequent coronary artery bypass graft (CABG) surgery. This study sought to compare immediate post-CABG complications between patients with and without previous coronary stenting. METHODS...
