Outcome and nutrition route of aged patients (over 90 years) who received mechanical thrombectomy for acute cerebral infarction

Abstract

  In our hospital, we retrospectively assessed the effects of using mechanical thrombectomy among the elderly patients (aged 90 years or older) as well as the route of nutrition administration at the time of discharge. From January 2015 to December 2018, we focused on the 18 elderly patients who underwent acute recanalization therapy: 7 males and 11 females (average age, 92.3 years old; mRS3‒5 in 8 cases (44.4%) before onset). The occlusion sites were ICA in 7 cases (38.9%) and MCA in 11 cases (61.1%). In regard to the treatment used, the following were administered: IV‒tPA in 8 cases (44.4%), SR in 9 cases (50%), SR＋Penumbra in 8 cases (44.4%), and SR → PTA in 1 case (5.6%). The recanalization rates were 100% for TICI2b‒3 in 18 cases (100%), 83% for mRS3‒5 in 15 cases, 0% for mRS6 in 0 cases (0%), and 16.7% for mRS0‒2 in 3 cases at discharge. The DTP average was 67.8 minutes and PTR average 81.4 minutes. In 11 cases (61.1%), the nutrition administration was done orally. Among elderly patients who underwent mechanical thrombectomy, the pre‒symptomatic mRS3‒5 and recanalization rates were high. Furthermore, we believe it is necessary to obtain cases of acute cerebral infarction among the elderly patients to judge the indication, although it is important not to limit the indication by age alone.
