Cím:Correlation between calcium, water contents and ultrasonographic appearance of atherosclerotic lesions of carotid artery lesions / Béla Fülesdi, Szabolcs Farkas, Zoltán Gyöngyösi, Péter Siró, Dániel Bereczki, József Bacsó, László Csiba

Megjegyzések:Background We tested the hypothesis whether there is a correlation between the echogenicity and calcium and water contents of carotid plaques. Patients and methods Ninety carotid befurcations from 45 deceased patients were removed during autopsy. Thirty-four plaques were categorized as homogenous echolucent (HEL), homogenous echogenic (HEG) and heterogenous (HE) plaques based on premortem B-mode image. Water content was expressed in % of wet weight. Ca was determined by proton-induced X-ray emission and expressed in ppm. Relative optical density of the B-mode images was analyzed offline using a computer program. Results HEL plaques had lower Ca content (medians and IQRs: 6,145 [4,465?6,536?ppm]) compared to HEG (74,100 [15,300?1,44,500?ppm]), P ? 0.001). HE plaques showed an intermediate calcium content (7,310 [4,840?9,920?ppm]) that was statistically not different from echolucent plaques. Water content of HEG plaques was statistically not different from HEL and HE (HEG:53.5 [35.5?64%], HEL: 73.5 [69.7?78.5%], HE: 70.6 [67.4?73.9%]). HEG plaques had the highest relative optical densities (196 [188?217%]). HEL and HE had similar relative optical densities (HEL: 176 [164?187%], HE: 164 [144?188%], respectively). A significant positive correlation was found between the Ca content and relative optical density of plaques. Conclusions Echogenicity of carotid plaques increases along with their calcium content. Water content may be an important factor in differentiation of different plaques.

Cím:Assessment of malformations, variations and diameters of vessels forming the circle of Willis : An autopsy study in a non-cerebrovascular cohort / Orosz László, Gyöngyösi Zoltán, Susán Zsolt, Siró Péter, Hoksbergen Arjan Willem, Csiba László, Fülesdi Béla

Megjegyzések:Background a purpose The collateral capacity of the circle of Willis (CoW) may play an important role in the development of ischemic strokes. The occurrence of classical polygon shows wide geographical variations and morphological data on diameters of the Willisian collaterals are scarce. We aimed to assess CoW variations and vessel diameters in a Central European cohort. Subjects and methods CoWs were removed during routine autopsy. The morphological pattern of the circles was recorded. The prepared circles were then put between two glass plates and tightly compressed. The length of the vessels and half of the circumference were measured under a light microscope enabling measurement with an approximation of 0.1?mm. Vessel diameters were calculated from vessel circumference. Results A total of 110 circles were analysed. Incomplete circles (missing one or two segments of CoW) were found in 25 cases (22.7%). Any forms of anatomical variations were detected in 14 cases (12.7%). When applying the <1?mm diameter threshold for analysis, 36 anterior communicating arteries (32.7%), 53 right posterior communicating arteries (48.2%), 73 left posterior communicating arteries (66.4%) and 18 posterior communicating arteries (16.3%) on both the sides were considered hypoplastic. Conclusions In patients without stroke in their history, complete CoW may be present in >60% of the cases. Our diameter data may serve as reference values for the Central-European population.
