“…Although these links are necessarily speculative at this time, it would be possible to test some of these factors individually (in particular, head position and body heating) on live infants by using ultrasound techniques to measure cerebrovascular blood flow. 16 Recent quantitative studies have indicated that no significant neuronal loss or gliosis is found in the brainstems of most SIDS infants. 17,18 These negative pathologic findings in SIDS brainstems are what would be expected after an acute brainstem infarct, because some hours of survival are needed before microscopic evidence for nervous system infarction becomes evident.…”

“…These studies are still needed for better understanding of the unification of improving the accuracy of velocity measurements, the angle range between the vessel and the beam, and the precise placement of the sample volume for quantitative Doppler spectral analysis. Such studies would be helpful to quantitatively increase the structure visualization, evaluate the most suitable probes and frequencies, setting equipment, and so on [11–13].…”

Aim. To present anatomic data in the ultrasound planes for the identification of the major veins and the venous sinuses in cerebrum and to establish the sonographic normal reference values for the visualization of vein vessels and vein sinuses and blood flow velocities. Methods. This study involved 55 healthy full-term neonates for transfontanellar color Doppler sonography. The imaging included both sagittal and coronal planes with LA332E probe, supplemented with PA240 probe as necessary. As low as reasonably achievable (ALARA) principle was obeyed, limiting Doppler exposure time and maximizing signal intensity by increasing gain rather than outputting transducer power settings. The output power was kept at a minimum level consistent with recording an adequate signal. Keeping the newborns in calm state, the total examination time which every neonate required was less than 5 min. All images were stored also in a workstation for further analysis. The description statistics and t-test for statistical analysis were used. Result. In all studied cases (100% cases), subependymal veins (SV), internal cerebral veins (ICV), Galen vein (GV), straight sinus (SS), superior sagittal sinus (SSS), and transverse sinuses (TS) were visualized. The visualization percentages of inferior sagittal sinus (ISS) or basal veins/Rosenthal veins (BV/RV) were lower than 100%. Based on vessel visualization percentage from high to low, the vessels were ordered as follows: SV, ICV, BV, SS, TS, ISS, and SSS. In SSS and TS, the pulsation percentage was 100%. The descending percentages of vessel pulsation were noted in SS, BV, ICV, and SV. On the basis of the mean of maximum velocities of the vessels from low to high, the vessels were ordered as follows: ISS, BV-L, BV-R, ICV-R, ICV-L, SV-L, SV-R, SSS, TS-L, TS-R, and SS. Conclusion. The measurements percent of visualization of cerebral deep veins was higher than the percent of cerebral venous sinuses. The pulsation percent of measurement and the velocities of cerebral venous sinuses were absolutely higher than the cerebral deep venous system. The pairs of vascular blood flow velocities were nonsignificantly different from one another.

“…The values of the resistive index, peak systolic, end diastolic, and time-averaged velocities of intracranial artery are determined by using Doppler techniques, and that is useful for the diagnosis, follow-up, and management of brain damage. 52,53 Hemorrhage: hemorrhage is associated with anticoagulant therapy or prematurity (►Fig. 12).…”

Pediatric patients show various extracardiac complications after cardiovascular surgery, and radiography and ultrasound are routinely performed in the intensive care unit to detect and evaluate these complications. This review presents images of these complications, sonographic approach, and timing of occurrence that are categorized based on their extracardiac locations and include complications pertaining to the central nervous system, mediastinum, thorax and lung parenchyma, diaphragm, liver and biliary system, and kidney along with pleural effusion and iatrogenic complications. This pictorial review will make it easier for medical doctors in intensive care units to identify and manage various extracardiac complications in pediatric patients after cardiovascular surgery.
