Abstract:
Objective To observe the dynamic changes of serum inflammatory factors after vertebral artery stenting and to investigate its clinical significance. Methods A total of 48 patients treated with vertebral artery stenting were included, and 48 patients only received cerebral angiography were used as a control group. The levels of soluble intercellular adhesion molecule-1 (sICAM-1), high-sensitivity C-reactive protein (hs-CRP) and tumor-necrosis factor-α (TNF-α) were detected before procedure (angiography), at 24 h, 48 h, 3 d, and 1 and 3 weeks after procedure (angiography). Results The serum levels of hs-CRP (4. 85 ± 0. 53 mg/L vs. 2. 57 ±0. 36 mg/L,P＜0. 05), TNF-α (2.42 ±0. 34 μg/L vs. 1. 08 ±0. 37 μg/L,P ＜0. 05) and sICAM-1 (449.43 ± 47. 16 μg/L vs. 269. 15 ± 37. 46 μg/L, P ＜ 0. 05) at 24 hours after procedure in the stenting group were significantly elevated compared with those before procedure. The Hs-CRP level (6.24 ± 0.59 mg/L) reached the peak at 48 hours after procedure. At week 3 (2. 51 ±0.29 mg/L), it returned to the level before procedure (2. 57 ±0. 36 mg/L); TNF-α level reached the peak at day 3 (2.30 ± 0.25 μg/L), and it remained higher level at week 3 (1. 89 ±0. 13 μg/L); the sICAM-1 level continued to rise at week 3 (296. 95 ± 59. 72 μg/L). The serum hs-CRP, TNF-α and sICAM-1 levels at 24 hours after procedure in the stenting group were significantly higher than those (3. 25 ±0.40 mg/L、J. 18 ±0. 19 μg/L and 336. 57 ± 50. 18μg/L) in the control group (all P＜0.05). Conclusions The serum hs-CRP, TNF-α, sICAM-1 levels were significantly elevated after vertebral artery stenting. It was suggested that the stenting caused a longer duration of inflammatory response.
