SPECT adds little to clinical risk prediction before aortic surgery; leaves open whether routine preoperative imaging improves outcomes.
Does preoperative dipyridamole-thallium SPECT and radionuclide angiography predict adverse cardiac outcomes in patients undergoing elective abdominal aortic surgery?
Routine preoperative screening with dipyridamole-thallium SPECT and radionuclide angiography may not be justified before abdominal aortic surgery, as clinical factors (age >65, known CAD) are better predictors of cardiac complications.
Baron et al. (1994) studied this question.
