RESUMO
The results of sensitivity analysis and ultrasonic techniques hagiographic 150 patients with vertebral artery syndrome caused by compression extravasal (ECVA) segment V(p), who underwent surgery on clinical. In assessing the sensitivity by a static cross-vertebral artery, vessel diameter, the condition of the lumen--Ultrasonic and hagiographic (SAG and MRA) techniques showed the same high sensitivity in the range 85-89% (P > 0.05), and according to such criteria as the dynamic permeability (89.2% vs. 34.2 and 45.5%), the value of ripple vascular (86.3% vs. 58 and 67%), the state of the perivascular tissue USDG figures were significantly higher than the data angiography (82.2% vs. 0 and 29%) (P < 0.05 for all tests). Comparative analysis of selective angiography, enhanced magnetic resonance angiography and ultrasound proposed method allowed us to determine their sensitivity. Thus, the sensitivity of selective angiography in extravasal vertebral artery compression is 57.1%, magnetic resonance angiography--88% and triplex ultrasound-- 91.3%.
