Megjegyzések:Transcranial color-coded sonography (TCCS) via the suboccipital approach allows direct and continuous visualization of the basilar artery (BA). In this study, we intended to evaluate the ability of native TCCS in visualizing the length of the BA by means of a comparison with postmortem measurements. METHODS: The BA was prospectively studied by TCCS shortly before death (median 3 days) in 46 moribund neurological patients (mean+/-SD age 71.1+/-13.1 years). The length of the BA was determined by measuring the distance between the vertebrobasilar junction and the deepest available flow signal in the top of the BA. During autopsy, photos of the vertebrobasilar system were taken to evaluate the true anatomic length and variations of the course of BA in situ, eg, straight, curved, or S-shaped. RESULTS: Comparison of the in vivo ultrasound measurements of BA length and postmortem data was possible in 44 of 46 cases. In the 2 remaining patients, the BA was occluded. The mean insonation depth of the vertebrobasilar junction was found at 66.9+/-7.1 mm. The mean BA length was 21.5+/-6. 8 mm by color-coded duplex and 32.9+/-6 mm anatomically (P<0.0001). The mean difference between color mode and anatomic findings was 11. 3+/-6.4 mm in the case of a straight BA (35 cases) and 16.3+/-4.8 mm in an anatomically tortuous course of the BA (9 cases). CONCLUSIONS: Color duplex imaging enables correct visualization of the proximal two thirds of the BA, but only exceptionally of its distal one third. A tortuous course of the BA leads to an underestimation of its anatomic length.

Megjegyzések:BACKGROUND AND PURPOSE: This study aimed to determine the correlation of in vivo ultrasound measurements of intima-media thickening (IMT), lumen diameter, andcross-sectional area of the common carotid artery (CCA) with correspondingmeasurements obtained by gross pathology and histology. METHODS: Sixty-sixmoribund neurological patients (mean age 71 years) underwent B-mode ultrasound ofthe CCA a few days before death. During autopsy, carotid specimens were removedin toto. Carotid arteries were ligated and cannulated for injection of ahydrophilic embedding material under standardized conditions. The carotidbifurcation was frozen and cut manually in 3-mm cross slices. Digital imageanalysis was carried out to determine the diameter and the cross-sectional areaof the frozen slices of the CCA. IMT was assessed by light microscope. Ultrasonicand planimetric data were compared. RESULTS: Mean measurements of lumen diameterand cross-sectional area were 7.13+/-1.27 mm and 0.496+/-0.167 cm(2),respectively, by ultrasound, and 7.81+/-1.45 mm and 0.516+/-0.194 cm(2),respectively, by planimetric analysis of the unfixed redistended carotid arteries(R(2)=0.389 and 0.497). The mean IMT was 1.005+/-0.267 mm by ultrasound and0.67+/-0.141 mm histologically, resulting in a mean difference of -31%.CONCLUSIONS: Transcutaneous B-mode ultrasound provides a reliable approach for invivo measurements of the cross-sectional area and, less exactly, of the lumendiameter of the CCA. Compared with histological results, in vivo ultrasoundmeasurements of the IMT are systematically larger.
