ABSTRACT Objectives. Analysis of the incidence of full block flow of the internal jugular veins (IJVs) either from extravascular either from endovascular origin. Methods. We investigated by Echo-Color-Doppler (ECD) 789 patients with CCSVI and MS (490 females, 299 males), mean age 45.4. We found 728 positive and 61 negative for CCSVI. Morphological and hemodynamic ECD data were recorded by a computerized MEM-net maps , and they were analyzed by MEM-net Clinical Analysis programs. Results. The analysis of the internal jugular veins showed: the block of the drainage by endovascular causes in 222 patients in supine position and 175 in the upright position (54% of total); the block of the drainage by extrinsic compression in 116 patients supine and in 232 in the upright (48% of total). The complete compressions of the IJVs in front position are equally distributed in the various segments observed (J1,J2 and J3). The passage from the supine to the upright position causes an increased incidence of compressions. The homo-lateral head rotation to the investigated IJV causes a significant increase of the extrinsic compressions. Such a high incidence of compression syndromes of the internal jugular veins prompts us to seek specific dynamic tests for assessment of their compression cause.
