Over the last ten years, transradial cardiac catheterization has been increasingly applied, primarily because of its lower incidence of complications compared to the femoral approach. However, one of the greatest flaws of the transradial approach is a relatively high incidence of catheterization failure (1%-5%). Anatomic variations of radial artery are ranked second among the reasons for this. ...

BACKGROUND The present study investigates how often a simultaneous fluorescein and indocyanine green (ICG) angiography had therapeutic consequences and if it is useful as a clinical routine diagnostic tool. PATIENTS AND METHODS 502 consecutive simultaneous angiographies in eyes with exudative macular degeneration were retrospectively studied. RESULTS A classic extra- or juxtafoveolar choroi...

Magnetic resonance angiography (MRA) is a non-invasive technology that can be used for diagnosis and monitoring of cardiovascular disease; the number one cause of mortality worldwide. Hyperpolarized imaging agents provide signal enhancement of more than 10, 000 times, which implies large reduction in acquisition time and improved spatial resolution. We review the role of hyperpolarized 13C agen...

OBJECTIVE The purpose of this study was to perform a clinical analysis of nine patients with giant aneurysms managed with endovascular embolization. METHODS From March 2000 to September 2009, nine cases of giant intracranial aneurysms were treated (five unruptured and four ruptured). The nine patients included two males and seven females who were 47 to 72 years old (mean, 59.2 years old). The...

coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...

Pseudoaneurisms are arterial wounds that affect all layers of an artery; although very rare they mostly lethal and most them iatrogenic. Herein, we present two different cases hepatic artery pseudoaneurysms derived from previous surgeries which were assessed by computed tomography angiographies consequent conservative endovascular approaches with arteriographies, posterior cannulations the plac...

SCIENTIFIC BACKGROUND Various diagnostic tests including conventional invasive coronary angiography and non-invasive computed tomography (CT) coronary angiography are used in the diagnosis of coronary heart disease (CHD). RESEARCH QUESTIONS The present report aims to evaluate the clinical efficacy, diagnostic accuracy, prognostic value cost-effectiveness as well as the ethical, social and leg...

conclusions routine predilation of the sb in provisional stenting of true bifurcation lesions seems to be ineffective and might be associated with some undesirable consequences. still, there are some complex ostial lesions of the sb which could benefit from predilation. patients and methods sixty patients with true bifurcation lesions according to the medina classification were included in the ...
