Objective: To study correlation among number (n), diameter (d) and blood reflux time (t) and the Left Common Iliac Vein (LICV) stenosis degree of the expansion of Perforating Veins (PVs), so as to guide the clinical formulation and adjust the treatment plan.
Methods: Retrospective analysis of 45 PVs patients with LCIV in different degrees of compression in our hospital from 2010 to 2012 was done. LCIV was divided into 50-69%, 70-99%, 30-49% and occlusion of the stenosis in order to avoid the error of the left iliac vein stenosis. Pearson correlation analysis among the number, diameter and blood reflux time of PVs and LCIV were performed.
Results: Pearson correlation analysis among the number, diameter and blood back flow time of PVS, and the degree of stenosis was done, and these results showed that correlation coefficients among the number, diameter and blood return the PVs between flow time and the degree of stenosis were rpn= 0.872, rp-d=0.934, rp-t=0.891 (P<0.001), respectively. The two variables exists positive correlation and correlation was significant.
Conclusion: With the increase of LCIV stenosis, the number of PVs and the diameter increased, and the time of blood flow were prolonged.
