150 males, aged from 40 to 69, with such risk factors of atherosclerosis development as smoking, arterial hypertensy, hyperlipedimy, inherited and psycho-emotional factors and/or its initial clinical presence were examined. While ultrasound examining in 90 (60%) cases atherosclerotic lesions in common carotid artery was found in intima-media layer thickening. 35 patients ran through direct antiotherogen therapy: VERAPAMYL - 80 Mg/24 hours and ALLYCOR 300 Mg/24 hours together with diet and 22 patients s (control group) were recommended diet only. All patients were examined by ultrasound in dynamics in every 3 months during 2 years. Simultaneously there was ultrasound examination of blood atherogensity in dynamics. While taking VERAPAMYL and ALLYCOR, blood atherogensity significantly decreased in 2 weeks after the treatment started, in 5 months, in 5 months of treatment there was no blood accumulation of lipids in cells while the level of common cholesterin did not change significantly. Progress of atherosclerotic process in common carotid artery did not occur in people younger 60 y.o. (n = 30) while therapy and diet, while in people older than 60 y.o. (n = 5) there was tendency of intima-media structure growth. Analyses of intima-media structure in the control group showed progress of atherosclerotic process in all cases (from 1,18 ( 0,05 mm to 1,26 ( 0,05 mm, p < 0,05) as well as there was more rapid atherosclerotic progress in people older 60 y.o. Thus the intima-media structure monitoring confirms antiatheronensity effect of the therapy implemented.

Colour Doppler Sonography in The Diaguosis of Carotid CkcIusive Disease Z. Petkovic, S. Milatovic, S. Tasic, V. Milojkovic. Institute of Radiology NIS, Serbia, Yugoslavia

Carotid disease is a very important element in the ethiology of ischemic cerebrovascular insult. 67% of

cerebrovascular insults is caused by tromboembolic attats from the carotid bifurcation. Besides, this localisation is surgically accessible so that correct and timely diagnosis as well as appropriate therapy can prolong a patients life, prevent invalidity and improve the quality of life. 469 patients were examined by colour Doppler sonography on Acuson 128 xp with a linear 7.5 Mhz probe. In all the patients computerised tomography was also performed, while in 45 patients comparative angiography was also done. 47,63% of the examined patients were males while 52,26 were females. Presence of absence of atermatous lesion in patients was estimated, as well as degree of stenosis, morphological characteristics of plaque in sense of existence, ulcerations and haemoragy. In 39% of the examined lesion was present on one side, while in 61% of the examined patients atermatous lesion existed on both sides. Significant stenosis was found on ICA in 27 patients, occlusion ICA in the 6, while one sided occlusion CCA was found in one patient. Colour Doppler sonography is a non invasive and comfortable method which points to the morphological and chemodynamic status of extracranial segment in carotid blood vessels. This method enables setting of correct indications of angiographic examination and eventual surgery.

Doppler Sonography of the kciliares breves in Patients with Low Tension Glaucoma and with Retinitis Pigmentosa

V. Klingmueller, H. Stroh, K.G.* Schmidt KG. Department of Diagnostic Radiology and *Department of Ophthalmology, Justus Liebig University, Giessen, Germany Introduction: The choroid of the eye, a low resistance vascular structure carrying 85% of the ocular blood flow, provides nourishment to and removal of potential toxic waste products from the non-vascularized outer layers of the retina, macula, and optic disc region. The choroid is supplied by A.ciliares breves, small vessels on the rear side of the bulbus. Choroidal perfusion is reduced in low tension glaucoma patients and may be reduced in retinitis pigmentosa patients. The objective of this study was to establish the Doppler sonography of the A.ciliares breves as a method to measure the choroidal perfusion. Method: 20 healthy subjects (mean age: 28 years), 10 patients with retinitis pigmentosa, and 10 patients with low tension glaucoma participated in the study. Doppler
