Development of Digital Subtraction Angiography for Coronary Artery

Digital subtraction angiography in angioplasty of total coronary artery occlusion.

This report describes a digital subtraction angiographic technique used to simultaneously display the proximal and distal segments of three totally occluded coronary arteries in two patients undergoing percutaneous transluminal coronary angioplasty (PTCA). The advantage of this technique over routine cineangiography for PTCA of total occlusions is illustrated.

Reoperation for coronary artery disease: devised management for reoperation including digital subtraction angiography.

Between December 1990 and August 1999, a consecutive series of 494 patients underwent coronary artery bypass grafting, while 19 (3.8%) patients underwent isolated reoperative coronary bypass grafting. The mean age of 16 males and 3 females who underwent reoperation was 63.4 +/- 6.4 years. The mean interval from the initial operation to reoperation was 50.7 +/- 61.0 months (range 3 days to 16 ye...

MR Digital Subtraction Angiography

Analysis of Subtraction Methods in 3D Contrast-Enhanced MR Digital Subtraction Angiography Yuexi Huang Master of Science 2001 Department of Medical Biophysics University of Toronto 3D Contrast-enhanced MR angiography is promising as a replacement to catheter-based x-ray angiography due to its non-invasive nature. However, the image quality of MR angiography is still inferior to that of x-ray an...

Digital subtraction angiography of a persistent trigeminal artery variant.

Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms. On the other hand, a persistent trigeminal artery variant feeding both the anterior inferior cerebellar artery and the posterior inferior cerebellar artery territory is ve...
