Abstract


In 63 patients with lumbar spinal stenosis, it was defined the relationship of sonographic parameters of the inferior vena cava and pseudoclaudication. Evaluated fluctuating data of volumetric blood flow rate driven by provocation test in patients with pseudoclaudication showed the average value of the sensitivity of this method (0.64), but overdiagnosis rate reaches significant levels (0.71) that requires additional verification tests to confirm a causal relationships.
