Computed tomographic assessment of coronary artery bypass grafts.

چکیده
Twenty four patients with 65 coronary artery bypass grafts were studied by computed tomography and angiogrphy within a 10 day period in order to assess graft patency and graft flow. In the assessment of graft patency computed tomography had an accuracy of 93% and in that of graft flow one of 91%. These results indicate that computed tomography is an accurate method for assessing graft patency and flow and is useful in the investigation of certain groups of patients who have had coronary artery bypass graft surgery.

Improved noninvasive assessment of coronary artery bypass grafts with 64-slice computed tomographic angiography in an unselected patient population.
OBJECTIVES In this prospective evaluation we investigated the accuracy of 64-slice computed tomography angiography (CTA) in an unselected but symptomatic patient population for detection of stenoses in bypass grafts when compared with invasive angiography. BACKGROUND The assessment of significant stenosis in bypass grafts is important for patients with recurrent angina symptoms after bypass s...

INTRODUCTION AND OBJECTIVES Although it has been demonstrated that the diagnostic accuracy of computed tomography in the non-invasive assessment of major epicardial coronary arteries is high, only a few studies have evaluated the technique's reliability in assessing coronary artery bypass grafts. The aim of this study was to determine the diagnostic accuracy of multidetector computed tomography...

BACKGROUND Multidetector computed tomographic angiography (MDCT) has been shown to allow detection of coronary artery bypass graft (CABG) occlusions and stenoses. However, the assessment of native coronary arteries in addition to CABG has thus far not been sufficiently validated. METHODS AND RESULTS Fifty patients with a total of 138 CABG (34 mammary grafts, 3 radial grafts, 101 venous grafts...
متن کاملMulti-detector computed tomography in coronary artery bypass graft assessment: a meta-analysis.
Multi-detector computed tomography (MDCT) has become an alternative to coronary angiography in diagnosis of graft occlusion and stenosis after coronary artery bypass. A literature search was performed for studies comparing angiography to 8-slice, 16-slice, and 64-slice MDCT in the assessment of coronary grafts. In assessing occlusion, 14 studies produced pooled sensitivity of 97.6%, specificity...
متن کاملComputed tomographic imaging in planning redo cardiac surgery after coronary bypass grafting — a roadmap to safety
Patent coronary artery bypass grafts are at risk of injury during redo cardiac surgery. In particular, damage to a patent left internal mammary artery (LIMA) graft during repeat surgery is a well-described and potentially lethal complication [1]. Precise anatomical information is important for planning the surgical approach in reoperative cardiac surgery. The standard preoperative work-up inclu...
