Focal arterial injuries of the proximal extremities: helical CT arteriography as the initial method of diagnosis.

Purpose: To present our experience with helical computed tomographic (CT) arteriography as the initial diagnostic examination in patients suspected to have focal arterial injuries of the proximal extremities.

Materials And Methods: During 19 months, 142 arterial segments in the proximal portions of the extremities of 139 patients with trauma were evaluated with helical CT arteriography. CT arteriograms were interpreted on site by the radiologist in charge of emergency procedures and retrospectively with consensus interpretation between two radiologists.

Diagnostic performance of helical CT angiography in trauma to large arteries of the extremities.

Purpose: The purpose of this work was to assess the performance of helical CT angiography (CTA) in the diagnosis of injuries to large arteries of the extremities.

Method: We performed helical CTA on 45 consecutive patients referred for conventional angiography for evaluation of suspected arterial injuries after sustaining trauma to the extremities (13 upper, 32 lower). Two radiologists interpreted the helical CTA studies independently.

Prevalence of hepatitis B surface antigen among women receiving prenatal care at the Palm Beach County Health Department.

Pregnant women receiving prenatal care at the maternity clinics of the Palm Beach County Health Department were tested for hepatitis B surface antigen. Routine screening of pregnant women for the antigen is discussed. The results of this study indicate the need for routine screening of our medically indigent pregnant population.
