Patients with coronary artery disease (CAD) show a high prevalence for concomitant atherosclerotic peripheral arterial disease (PAD). On the other hand, PAD seems to be an additional risk factor for cardiac events. We evaluated the correlation between arterial pathologies as found in whole-body MR angiography and coronary artery calcification (CAC) detected by electron beam computed tomography (EBCT) and multislice CT (MSCT).
Two hundred and twenty-eight patients (161 men; 67 women) with suspicion for CAD/known CAD underwent whole-body contrast-enhanced MR angiography (wb-ce-MRA) and EBCT/MSCT. An atherosclerosis index was calculated for each patient Index = (40)Sigma(n=1) w(i) with w(i) being the grading of the stenosis of the i (ten) of 40 arteria segments (grade: 0 - no plaque; 1 - plaque - < or = 50 % stenosis; 2 - > 50 % stenosis - < or = 90 % stenosis; 3 - > 90 % stenosis - < 100 % stenosis; 4 - occlusion). Correlations between CAC and atherosclerosis index were performed.
Wb-ce MRA and CAC correlate only moderately in this population. An atherosclerosis index 8 renders a positive predictive value for a CAC 100 of 63.3 %.
An atherosclerosis index as defined in this study does not fully correlate with the extent of CAD as revealed by catheter angiography or EBCT/MSCT, but it might theoretically mirror the increased risk by PAD. It thus might be a promising complementary parameter for the prediction of cardiac events. Future studies need to show its possible additional predictive impact.

To present a case in which thrombin was injected percutaneously to treat an aortic pseudoaneurysm.
A 63-year-old man developed a large pseudoaneurysm in the abdominal aorta after surgical fenestration and patch aortoplasty for acute type B aortic dissection with malperfusion syndrome. Transcatheter delivery of 1500 units of thrombin resulted in complete thrombosis of the pseudoaneurysm sac. No complications occurred. Twelve months after the procedure, the pseudoaneurysm was completely resolved on computed tomography.
Thrombin continues to prove its safety and efficacy for the treatment of pseudoaneurysms at numerous anatomical sites, including the abdominal aorta.
