BACKGROUND: Popliteal artery aneurysms (PAA) are the most common peripheral artery aneurysms. Most common cause is arteriosclerosis. Acute thromboembolic limb ischemia and rupture of the PAA depict severe complications. Diagnostic tools for identifying PAAs are (Doppler) ultrasound, CT/MR angiography and DSA.
OBJECTIVE: The aim of the present retrospective single-center study is to assess the application and safety of CEUS for assessing untreated and treated PAAs.
METHODS: 13 patients were included in this study on whom CEUS was performed between 2007-2016. CEUS examinations were performed and interpreted by an experienced single radiologist (EFSUMB Level 3).
RESULTS: CEUS allowed for the detection of PAAs in all cases. CEUS allowed for detection of partial thrombosis of PAA in 7/8 of untreated patients, proper exclusion of PAA upon femoro-popliteal bypass in 3 patients, incomplete exclusion of PAA upon femoro-popliteal bypass in 1 patient and ruling out of in-stent stenosis in 1 patient.
CONCLUSIONS: CEUS is a useful and safe tool for in real-time evaluation of PAAs in the pre-/post-treatment status. In addition to conventional (Doppler) ultrasound and as an alternative tool to more elaborate imaging modalities, CEUS might be integrated in the future diagnostic work-up and follow-up of PAA patients.

This study tested the validity of the School-aged Assessment of Attachment (SAA) in terms of matches from the well-validated Preschool Assessment of Attachment (PAA) to the SAA 6 months later. It also addressed validity in terms of mental health services and measures of stress, depression and anxiety.
OBJECTIVE: Children\'s SAA classifications were predicted to match their 6 months\' previous PAA classifications and indicators of maternal, child and family stress. The study used a two-group comparative design, involving normative and clinical children and their mothers.
METHODS: The participants were 50 children between 5.5 and 5.9 years of age. Each child participated with his or her mother in a PAA, and then 6 months later each child responded to the SAA story cards as well as self-report assessments of stress, anxiety and depression.
RESULTS: Concordance of A, B, C and A/C attachment classifications was found between the PAA and SAA in 34 of 48 children. There was a strong relation between referral status (clinical or normative) and both PAA and SAA attachment classifications. In every non-matching case, a normative child had an attachment classification indicative of risk, indicating that the direction of errors was false positives as opposed to false negatives.
CONCLUSIONS: This evidence supports the validity and clinical utility of the SAA.
