The choice of sedation for computed tomography in children: a prospective evaluation.

abstract：:Twenty-one patients with prostate cancer underwent intermittent arterial infusion chemotherapy with an implanted reservoir and alteration of the intrapelvic blood flow. One internal iliac artery was embolized with steel coils so that the drugs would perfuse throughout the tumor through a single tube. Angiography perfo...
