| [ Summary ] |
The number of cases requiring reconstruction of blood access has increased recently, in parallel with the number of long term dialysis patients. DSA, 3D-CTA and MRA are evaluated as diagnostic methods for blood access troubleshooting. DSA, even with few contrast mediums, can produce high quality imaging and is able to be converted to use for interventional radiology. 3D-CTA is expensive and inconvenient now, and is difficult to use for real-time imaging. However, this technology can easily help us to understand 3D anatomy. The resolution of 3D-CTA is almost as good as that of DSA. The resolution of MRA is worse than others methods, but it is a non-invasive method, not requiring a contrast medium. In summary; 3D-CTA is a superior method for evaluating blood access in complicated vessel systems. |
