Evaluation of the Relationship Between Radial Artery Intima Media Thickness and Complications at the Intervention Site After Radial Angiography.

The present study investigated the relationship between pre-procedural radial intima-media thickness (rIMT) and radial artery thrombosis (RAO) in patients undergoing angiography using a transradial approach (TRA). Patients (n = 90) who underwent cerebral or peripheral arterial angiography using TRA were included in the study. Ultrasonographic evaluation was performed before and 12 h after the procedure. Preoperative rIMT measurement was performed at the distal radial artery. Presence of radial artery occlusion was evaluated by ultrasonography after radial catheterization and revealed occlusive thrombus in the radial artery in 13 patients. rIMT was found to be statistically significantly higher in patients with thrombus (P < .05). When it was evaluated whether there was a correlation between age and rIMT, a positive significant correlation was found (P < .01). Our study suggests that increase of rIMT may be a risk factor for RAO in the intervention area. Before the procedure, ultrasound (US) assessment of the radial artery may be useful in determining the risk of occlusion. Thus, RAO-related technical risk factors (procedure time, number of punctures, sheath thickness, etc.) can be managed more carefully in patients having radial angiography.

Intergenerational transmission of psychological trauma: A structural neuroimaging study.

Traumatic events have an important effect in human life and may lead to psychopathological disturbances by affecting the personal and social lives of individuals. Recently, various studies have been reported in the literature showing that the traumatic experiences may be associated with intergenerational psychopathologies. However, there is limited data regarding the neuroimaging studies investigating changes in brain structures in children of traumatized mothers. In this study, we aimed to investigate the potential changes in the hippocampus and amygdala volumes in the children of mothers exposed to mass trauma. The traumatic event experienced by the mothers was the two devastating earthquakes they experienced when they were teenagers. Hippocampus and amygdala volumes were evaluated in magnetic resonance imaging of 40 children whose mothers were exposed to earthquakes and 27 children in control group. Bilateral amygdala volumes were significantly smaller in the children of mothers exposed to earthquake compared to the control group. In addition, right amygdala and hippocampus volumes were smaller in children of mothers exposed to earthquakes than left. This is one of the pioneering neuroimaging studies on the intergenerational transmission of trauma. Our study shows that there may be a potential relationship between intergenerational trauma and various brain structures.
