The results showed that age ≥65 years, no use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, collateral circulation <grade 2, thrombosis burden ≥4 points, diameter of target lesion ≥3.5 mm, TA, and blood glucose >8 mmol/L were independent factors related to NRP [35]. This evidence concerns the gene ACE and Venous thrombosis.
