Preoperative thallium scintigraphy may not predict adverse outcomes in elective vascular surgery; leaves open need for larger prospective validation.
Does preoperative dipyridamole thallium-201 scintigraphy predict adverse cardiac outcomes and perioperative ischemia in patients undergoing elective vascular surgery?
Preoperative dipyridamole thallium-201 scintigraphy did not significantly predict adverse cardiac outcomes or perioperative ischemia in patients undergoing elective vascular surgery, suggesting routine use may not be warranted.
Mangano et al. (1991) studied this question.
