Study Questions : Chapter 12

* 1.) Which characteristic is associated with a highrisk access, resulting in a >3% complication rate?
* 2.) Which closure device has been shown to be associated with higher complication rates than manual compression in 2 meta-analyses?
* 3.) In order to optimize the angiographic assessment of a suspected ostial right subclavian stenosis, the operator should typically station the image intensifier in what position?
* 4.) A patient has a TASC B superficial femoral artery stenosis. Self-expanding stents have what advantage over balloon-expandable stents in this vascular territory?
* 5.) A nonobese patient undergoes angiography in a modern, well-equipped endovascular suite. What duration and dose of radiation delivered to the interventional reference point merit warning the patient that he or she is at risk for radiation injury?
