ABSTRACT

Objective:To investigate the efficacy of different preferred thrombectomy strategies for embolic acute vertebrobasilar artery occlusion (AVBAO).Methods:Forty-four patients with embolic AVBAO who underwent endovascular treatment in Department of Neurology, Nanyang Central Hospital from January 2019 to June 2021 were included in the study. Patients were divided into stent-retriever thrombectomy group ( n=27) and aspiration thrombectomy group ( n=17) according to different preferred thrombectomy strategies. Modified Rankin scale (mRS) was used to evaluate the prognoses of these patients 90 d after surgery; the differences of clinical data, surgery-related characteristics, prognoses and complications between the two groups were compared. Results:There was no significant difference between the 2 groups in terms of time from onset to puncture, sites of target vessel occlusion, proportion of patients accepted intraoperative remedial measures, and successful recirculation rate of target vessels ( P>0.05). Compared with the aspiration thrombectomy group, the stent-retriever thrombectomy group had significantly decreased utilization rate of middle catheters, significantly increased retrieval attempts in thrombectomy, statistically lower re-recanalization rate of first-time thrombectomy on the target vessels, significantly longer time from puncture to re-recanalization, and significantly higher incidence of new embolism ( P<0.05). There was no significant difference between the 2 groups in incidences of vascular rupture and postoperative spontaneous intracerebral hemorrhage (sICH), and good prognosis rate 90 d after surgery ( P>0.05). Conclusion:For embolic AVBAO patients, similar recanalization and short-term good prognosis can be obtained by aspiration thrombectomy to those by stent-retriever thrombectomy; besides that, aspiration thrombectomy has advantages as shorter recanalization time, less new embolic complications and higher re-recanalization rate of first-time thrombectomy.

ABSTRACT

Objective To explore the effect of different hyperbaric oxygen treatment (HBOT) on delayed neuropsychiatric sequelae followed carbon monoxide (CO) poisoning (DNS).Methods Patients diagnosed acute carbon monoxide poisoning (ACOP) or DNS due to CO poisoning in the hospital from October 2015 to October 2016 were included.Patients who died of ACOP or in persisting unconsciousness condition were excluded.Information of the patients were retrospectively collected including personal data,clinical features and treatment course of hyperbaric oxygen (HBO).All subjects were divided into two groups,consisting of cases who developed into DNS and who fully recovered,according toclinical symptoms.The differences of personal data,clinical features and treatment course of HBO were compared between the two groups.After adjusting the confounding factors,hyperbaric oxygen treatment program of the two groups were analyzed.Results DNS occurred in 39 patients with acute CO poisoning,while 130 patients were fully recovery.The ratio of patients over 55 years old or with smoking history in the DNS group were higher than that in the good outcome group (82.1% vs.60.8%,23.1% vs.10.8%).Patients who awoke from unconsciousness but left cognitive impairment were more likely to develop into DNS (P=0.017).Patients who treated with HBO within the first 24 hours,risk of developing into DNS were decreased(OR=0.14,P<0.01).At the same time,2 times per day and within the first 24 hours worked also as well.(OR=0.29,P=0.011).Even if patients who were given 2 times a day of HBO but not in the first 24 hours after poisoning,could not reduce the risk of evolving to DNS(OR=0.06,P>0.05);The proportion of patients in the good outcome group accepted HBO for more than six days after poisoning was higher than that in the DNS group (68.5% vs.48.7%).After adjusting confounding factors,patients who treated with HBO within the first 24 hours (OR=0.22,95%CI:0.09-0.52),2 times per day(OR=0.30,95%CI:0.10-0.87)and lasted for more than 6 days(OR=0.30,95%CI:0.10-0.87)were in a lower risk of involving to DNS.Conclusions For patients diagnosed ACOP,HBOT began in the first 24 hours,1 or 2 times per day or early sustaining to give HBO for more than 6 days could reduce the risk of DNS.
