Cím:No relationship between cerebral blood flow velocity and cerebrovascular reserve capacity and contemporaneously measured glucose and insulin concentrations in diabetes mellitus / Fülesdi, B., Limburg, M., Bereczki, D., Molnár, C., Michels, R. P. J., Leányvári, Z., Csiba, L.

Megjegyzések:Blood glucose and insulin concentrations have been reported to influence cerebral hemodynamics. We studied the relationship between actual blood glucose and insulin concentrations and resting cerebral blood flow velocity in the middle cerebral artery and cerebrovascular reserve capacity after acetazolamide stimulation. Thirty-six insulin-dependent diabetic patients in a state of good glycemic control were studied. Blood samples were taken for determination of glucose and insulin concentrations. Subsequently we measured resting cerebral blood flow velocities in supine position using transcranial Doppler, administered 1 g acetazolamide intravenously, and repeated the measurements after 5, 10, 15 and 20 minutes. Cerebrovascular reserve was calculated as the maximal percent increase after acetazolamide stimulation. Multiple regression was used for statistical analysis. Blood glucose levels were not correlated with resting blood flow velocity (R = 0.21, p = 0.22) nor cerebrovascular reserve capacity (R = 0.17, p = 0.32). Similarly, no correlation was found between insulin concentrations, resting cerebral blood flow velocity (R = 0.24, p = 0.22) and cerebrovascular reserve (R = 0.26, p = 0.24). Studying patients with long-term (> 10 years) and short-term (</= 10 years) disease duration yielded the same lack of correlation. We conclude that there is no significant correlation between contemporaneously measured glucose and insulin concentrations and either cerebral blood flow velocity or cerebrovascular reserve capacity in the middle cerebral artery in type 1 diabetic patients with good control.

Cím:Az arteria carotisok atheroscleroticus laesioinak vizsgálata diabetes mellitusban szenvedő cerebrovascularis betegekben / Fulesdi, B., Bereczki, D., Mihalka, L., Fekete, I., Siro, P., Leanyvari, Z., Valikovics, A., Csiba, L.
Dátum:1999
Megjegyzések:The aim of the study was to assess the incidene of atherosclerosis lesions on carotid arteries among diabetic subjects suffering from cerebrovascular accident. A further aim was to investigate the relationship between the severity of the carotid lesion, the stroke subtype and the fatal outcome. One hundred and sixty eight patients treated because of cerebrovascular accident at the Dept. of Neurology University Medical School of Debrecen were studied. The age of the patients, the duration of diabetes and hypertension were registrated. Based on duplex scanning carotid lesions were divided in 6 groups of severity (normal, intimal sclerosis, slight, moderately severe, severe stenosis and occlusion). Based on clinical signs and CT results stroke subtypes were divided into five groups (lacunar and non-lacunar infarctions, hemorrhages, normal CT and others). The relationship between severity of carotid lesions, stroke subtype and letal outcome was assessed using statistical tests. Carotid stenosis of different severity was detected in 60 per cent of the cases. Severity of stenosis was independent from duration of diabetes, but it was positively related to duration of hypertension (p = 0.016). In 1\3 of the patients lacunar strokes, in another 1\3 non-lacunar strokes were observed. No significant relationship was found between severity of carotid stenosis, stroke subtype and letal outcome of the patients (p = 0.53 and p = 0.26 respectively). Diabetic patients suffering from stroke have a higher incidence of carotid artery atherosclerotic lesions than diabetics with out stroke. A special attention should be paid to the carotid duplex sonography in order to detect diabetic cerebral macroangiopathies in early, asymptomatic stage.

Cím:Computed tomographic and transcranial Doppler sonographic findings in acute and subacute phases of middle cerebral artery strokes / Leanyvari, Z., Vastagh, I., Fulesdi, B., Szirmai, I., Lengyel, A., Csiba, L., Bereczki, D.
Dátum:2002
ISSN:0091-2751
Megjegyzések:The aim of this study was to compare the sensitivities of visual and densitometric analyses of CT scans and transcranial Doppler sonograms (TCD) in detecting early changes in acute stroke. METHODS: CT and TCD were each performed twice in 12 patients; first in the acute phase (within 28 hours of stroke onset), then in the subacute phase (mean +/- standard deviation, 6 +/- 3 days after onset) of a stroke. Hypodensity on the CT scans was evaluated visually, and the optical density of both the stroke region and the corresponding region on the unaffected side was measured. Measurement of flow parameters in the middle cerebral artery was carried out with TCD before or shortly (within 4 hours) after CT scanning. RESULTS: In the acute phase, blood flow velocities were significantly lower on the affected side than they were on the unaffected side (means, 42 +/- 13 and 55 +/- 25 cm/second, respectively; p = 0.012). Marked asymmetry in flow velocity was found in 3 of the 4 patients who had normal CT scans in the acute phase. The asymmetry in flow velocity disappeared by the sixth day after the stroke. The resistance index did not correlate with the final infarct size. CONCLUSIONS: In some patients, the use of TCD in acute stroke may show alterations that reflect tissue damage that is undetectable on CT. Therefore, CT and TCD should be considered complementary diagnostic tools in the acute phase of stroke.
