Penetrating zone II neck injury: does dynamic computed tomographic scan contribute to the diagnostic sensitivity of physical examination for surgically significant injury?
Dynamic CT scan contributes minimally to the sensitivity of physical examination in the diagnosis of surgically significant penetrating zone II neck injury. Diagnosis of esophageal injuries with dynamic CT scan appears no better than esophagography. CT scan has greater sensitivity than physical examination for the diagnosis of jugular venous injuries; however, the majority of these injuries do not require identification or surgical intervention.
These findings indicate that placental impedance has little clinically relevant impact on the UVP.
