OBJECTIVE To assess the clinical and angiographic results of the first clinical application of a new balloon expandable stent, the NIR stent, characterised by high longitudinal flexibility and low profile before expansion, and by high radial support and minimal recoil and shortening after expansion. DESIGN Single centre survey of unselected lesions in consecutive patients. SETTING Tertiary ...
BACKGROUND It remains unclear whether cilostazol, which has been shown to improve the clinical outcomes of endovascular therapy for femoropopliteal lesions, also reduces angiographic restenosis. METHODS AND RESULTS The Sufficient Treatment of Peripheral Intervention by Cilostazol (STOP-IC) study investigated whether cilostazol reduces the 12-month angiographic restenosis rate after percutaneo...
Chronic total occlusion of left main coronary artery is a very rare angiographic finding as majority of these patients do not survive long enough to undergo coronary angiography. We describe a patient with angiographic findings of chronic total occlusion of left main coronary artery with left coronary circulation collateralized from right coronary artery.
The use of abdominal angiography and transcatheter embolization has increased rapidly in the last few decades. Although improvement in angiographic techniques has made the procedure safe, ischemic colitis is a rare but potentially dreadful complication. We report a case of a 51-year-old woman who developed ischemic colitis following aortography, demonstrating that such angiographic studies may ...
When performing CT-guided procedures or angiographic procedures, radiologists performing procedures need to communicate with radiographers at a workstation behind radiation shielding glass. As shielding renders verbal communication impossible, we have developed a set of standardised hand signals for use at our department to help us achieve clear and efficient communication between radiologists ...
We retrospectively analyzed exercise treadmill and coronary angiographic data of 2,193 men to compare heart rate (HR) recovery with angiographic and mortality data during a follow-up study of 7 +/- 2.7 years. Only the first 2 minutes of HR recovery predicted mortality (p <0.001), and the HR decrease during the second minute of recovery predicted the presence of coronary artery disease (p <0.05).
We are developing three-dimensional imaging methods to portray vascular anatomy better, including noise-free display of vessels extracted from 3-D data sets, tree-based display, and reconstruction of angiographic data (preliminary work has resulted in the successful reconstruction of aneurysms from angiographic data). Fast, interactive display permits real-time manipulation of viewing orientation.
We describe a time-resolved, contrast-enhanced carotid MR angiographic technique using a 3D gradient-echo sequence in combination with a sensitivity-encoding scheme. We delineate the steps involved in generating the dynamic MR angiographic images, discuss issues related to image quality, and outline differences between this technique and recently reported similar methods that implement multiple...
Background—Outcomes of patients presenting with acute coronary syndromes are improved with an early invasive approach; however, approximately one third of these patients are treated medically after angiographic screening. We sought to assess the predictors of adverse cardiac events in patients with acute coronary syndrome assigned to medical management. Methods and Results—This substudy of the ...
BACKGROUND AND PURPOSE Flow diverters have been increasingly used lately in off-label, distal intracranial aneurysm treatments. Our aim was to evaluate the effectiveness of flow diverters in the treatment of middle cerebral artery bifurcation aneurysms and to analyze midterm angiographic patterns of regional flow modifications for safety and clinical outcomes. MATERIALS AND METHODS Consecutiv...
