Selection and nonoperative management of pediatric blunt trauma patients: the role of quantitative crystalloid resuscitation and abdominal ultrasonography.

One hundred thirty-nine pediatric blunt trauma patients 12 years of age or less were cared for using a protocol designed to identify which patients require aggressive surgical therapy and those who can be managed nonoperatively. Sixteen patients (average MISS score, 33) failed to respond to an estimated 20 cc per kilogram of crystalloid fluid resuscitation. Fifteen died, a mortality rate of 94%.

Computed tomography detection of transplant renal artery pseudoaneurysm.

Clinically unsuspected pseudoaneurysm formation of the arterial anastomosis in a patient with a renal transplant was initially diagnosed by computed tomography. This rare but serious complication can also be detected by ultrasound or radionuclide flow study, as shown in our patient. An awareness of this lesion and familiarity with its appearance can permit its early detection before exsanguinating hemorrhage occurs.
