Abstract 【Objective】To explore the value of collateral circulation in evaluating clinical curative effect and prognosis of patients with ischemic stroke.【Methods】Seventy-five patients with ischemic stroke admitted to our hospital between January 2014 and October 2015 were analyzed retrospectively. According to CT angiography (CTA), collateral compensation was evaluated, and according to this, the subjects were divided into collateral circulation group and non collateral circulation group. The imaging findings, neurological deficit scores (NIHSS) before and after treatment and prognosis in 1-year follow-up were compared between the two groups.【Results】The incidence rates of single lesion and occlusion in collateral circulation group (68.89%, 48.89%) were significantly higher than those in non collateral circulation group (40%, 16.67%) (P<0.05); The NIHSS scores in the collateral circulation group before treatment, 3 months and 1 year after treatment [ (8.17±1.02), (3.20±1.75), (0.88±0.76)] were significantly lower than those in the non collateral circulation group [ (10.35±1.28), (5.07±1.89), (2.76±1.28)] (P<0.05); 1 year after treatment, the excellent and good rate of prognosis in the collateral circulation group (68.89%) was significantly higher than that in the non collateral circulation group (43.33%) (P<0.05).【Conclusion】The establishment of collateral circulation is closely related to the degree of vascular stenosis, which is of certain value in evaluating the clinical curative effect and prognosis.
