ObjectiveTo investigate the influencing factors for persistent hypotension after carotid artery stenting (CAS). MethodThe clinical data of 140 patients with carotid artery stenosis treated with CAS were retrospectively analyzed, and the patients were divided into the occurrence group or the non-occurrence group according to the occurrence of postoperative persistent hypotension. The data of the two groups were compared, and multivariate logistic regression was used to analyze the influencing factors for persistent hypotension after CAS. ResultsAmong the 140 patients with carotid artery stenosis, 40 patients developed persistent hypotension after CAS, with an incidence of 28.57% (40/140). There were statistically significant differences in age, stenosis site on the surgical side, stenosis severity on the surgical side, surgery time, ulcer plaque condition, stent post-dilatation condition, and history of hypotension between the two groups (all P＜0.05). The results of multivariate logistic regression analysis showed that age ≥65 years, bulb stenosis on the surgical side, severe stenosis on the surgical side, surgery time ≥ 1 h, ulcer plaque, stent post-dilation, and a history of hypotension were independent risk factors for persistent hypotension after CAS (all P＜0.05). ConclusionAge≥ 65 years, bulb stenosis on the surgical side, severe stenosis on the surgical side, surgery time ≥ 1 h, ulcer plaque, stent post-dilation, and a history of hypotension are independent risk factors for persistent hypotension after CAS in patients with carotid artery stenosis.
