Evaluation of vascular recanalization rate and nerve injury of mechanical thrombectomy combined with rt-PA thrombolysis in treatment of acute cerebral infarction
Objective:To investigate the vascular recanalization rate of mechanical thrombectomy combined with recombinant tissue-type plasminogen activator (rt-PA) thrombolysis in the treatment of acute cerebral infarction and the effect on the nerve injury in patients.Methods:A total of 90 patients with acute cerebral infarction who were treated in our hospital between January 2016 and January 2019 were retrospectively analyzed and divided into the control group (n=46) receiving rt-PA thrombolysis and the observation group (n=44) receiving mechanical thrombectomy combined with rt-PA thrombolysis. The differences in vascular recanalization rate 24 h after treatment as well as serum levels of inflammatory mediators [interleukin-1 (IL-1), interleukin-6 (IL-6), interleukin-7 (IL-7), interleukin-17 (IL-17) and hypersensitive C-reactive protein (hs-CRP)], nerve injury markers [brain-derived neurotrophic factor (BDNF), neuron-specific enolase (NSE) and S100B protein (S100B)] and neurotransmitters [glutamate (Glu) and 5-hydroxytryptamine (5-HT)] before and after treatment were compared between the two groups of patients.Results: 24 h after treatment, the vascular recanalization rate of the observation group was higher than that of the control group (P<0.05). 24 h after treatment and 1 week after treatment, serum IL-1, IL-6, IL-7, IL-17 and hs-CRP levels in the observation group were lower than those in the control group;BDNF level was higher than that in the control group, while NSE and S100B levels were lower than those in the control group;Glu and 5-HT levels were lower than those in the control group (P<0.05). Conclusions: Mechanical thrombectomy combined with rt-PA thrombolysis can increase the early postoperative vascular recanalization rate in patients with acute cerebral infarction, and it also plays an active role in alleviating nerve injury.
