Evaluation of venous and arterial conduit patency by 16-slice spiral computed tomography.
BACKGROUND Computed tomography has been shown to be useful in the evaluation of aortocoronary bypass grafts (CABG). This is the first prospective study to evaluate the accuracy of a new-generation scanner in the detection of patency and significant stenoses (>50% decrease in diameter) of venous and arterial grafts in patients with previous CABG. METHODS AND RESULTS In 96 patients (80 males, m...
متن کاملImaging and evaluation of coronary artery bypass graft patency by 16-slice multidetector computed tomography.
INTRODUCTION The purpose of this study was to evaluate the patency of coronary artery bypass grafts (CABGs) while assessing the capabilities and limitations of 16-slice multidetector computed tomography. METHODS We studied retrospectively 19 patients (13 men, 6 women), over an 18-month period. All patients had undergone CABG surgery 3 months to 7 years earlier. Two patients were examined on a...
متن کاملComparison of 16-slice computed tomography with conventional angiography to evaluate coronary artery stent patency.
OBJECTIVE In this study, we evaluated the utility of 16-slice MDCT (multidetector computed tomography) to assess stent patency after coronary artery stenting. MATERIALS AND METHODS Retrospective ECG-gated CT-angiography using 16-slice MDCT was performed in 52 consecutive patients with coronary artery stents. Qualitative assessment of 61 coronary stent lumens by MDCT is reported, and the reaso...
متن کاملNon-invasive assessment of coronary artery bypass graft patency using 16-slice computed tomography angiography
BACKGROUND Invasive coronary angiography is the gold standard means of imaging bypass vessels and carries a small but potentially serious risk of local vascular complications, including myocardial infarction, stroke and death. We evaluated computed tomography as a non-invasive means of assessing graft patency. METHODS Fifty patients with previous coronary artery bypass surgery who were listed...
متن کاملAssessment of coronary artery stents by 16 slice computed tomography.
OBJECTIVE To analyse coronary stents with multislice spiral computed tomography (MSCT) in comparison with coronary angiography. PATIENTS AND METHODS 310 patients referred for conventional coronary angiography underwent MSCT on the next day (16 x 0.75 mm cross section, 420 ms rotation, 110 ml contrast agent intravenously at 4 ml/s). Two independent blinded reviewers analysed the MSCT. RESULT...
