Abstract:

Objective

To explore the medium- to long-term prognosis and its influencing factors in elderly patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) after stent retriever thrombectomy.

Methods

A total of 100 elderly patients with AIS-LVO who underwent stent retriever thrombectomy at Hebei Petro China Central Hospital from January 2020 to September 2022 were enrolled and followed up for 6 months. Prognosis was evaluated for prognosis by modified Rankin scale (mRS), with scores of 0-2 defined as good prognosis and 3-6 as poor prognosis. Patients were divided into elderly group (age ≥ 80 years old) and non-elderly group (age<80 years old) based on their age. Group comparisons were performed using t-tests or Chi-square tests. Factors affecting prognosis were analyzed using logistic regression.

Results

Among 95 patients who completed follow-up, 51 (53.68%) had a good prognosis and 44 (46.32%) had a poor prognosis. Compared to the good prognosis group, the poor prognosis group had significantly higher proportions of patients aged ≥80 years, diabetes, coronary heart disease, carotid middle cerebral artery occlusion, poor reperfusion [modified cerebral infarction thrombolysis blood flow classification (mTICI)<2b], the National Institutes of Health stroke scale (NIHSS) score ≥15 at admission, NIHSS score>15 at 7 days post-operation, symptomatic intracranial hemorrhage (sICH), and cerebral hernia (all P<0.05). The onset-to-puncture time (OTP) and the puncture-to-reperfusion time (PTR) of poor prognosis group were significantly longer those in the good prognosis group, all the differences were statistically significant (all P<0.05). No significant differences were found in gender composition, underlying diseases, smoking history, alcohol consumption history, occluded site, trial of Org 10172 in acute stroke treatment (TOAST) classification, NIHSS score at admission, treatment methods, OTP, PTR, number of thrombus attempts, mTICI grading, sICH, and incidence of cerebral hernia formation between the elderly group and non-elderly group (all P>0.05), except that the good prognosis rate of the elderly group was significantly lower than that of the non-elderly group, and the NIHSS score at 7 days post-operation was significantly higher than that of the non-elderly group (P<0.05). Logistic regression analysis showed that age ≥ 80 years, diabetes, NIHSS score ≥ 15 at admission, NIHSS score>15 at 7 days post-operation, carotid middle cerebral artery occlusion, poor vascular recanalization (mTICI<2b) and sICH were independent risk factors for poor prognosis (all P<0.05).

Conclusion

Stent retriever thrombectomy for elderly AIS-LVO is safe and feasible, but patients aged ≥80 years benefit less. The diabetes, high NIHSS scores (admission and 7 days post-operation) carotid middle cerebral artery occlusion, poor vascular recanalization, and sICH are the main factors affecting the medium and long-term prognosis.
