RESUMO
Objective:To analyze the clinical characteristics of patients suffering from acute ischemic stroke (AIS) complicated with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods:Data of patients with AIS who visited the Second Affiliated Hospital of Soochow University from January 2015 to June 2020 and underwent polysomnography monitoring (PSG) in the sleep center were collected retrospectively. Patients were divided into OSAHS group and AIS only group. Demographic information of patients, general clinical data, hematological indicators of glucose and lipid metabolism and inflammatory markers, PSG parameters and neurological function scores were collected, including the National Institutes of Health Stroke Scale (NIHSS) on admission and the modified Rankin Scale (mRS) on discharge. We compared the differences between the two groups. In addition, OSAHS group were divided into good prognosis and poor prognosis subgroups according to mRS score. The differences between the two subgroups were compared.Results:A total of 112 AIS patients combined with OSAHS and 89 AIS only patients were included. The proportion of non-rapid eye movement stages 1+2 [(N1+N2) %], arousal index, the oxygen desaturation index (ODI), percentage of total sleep time with oxygen saturation<90% (TS90) in the OSAHS group were higher than those in the AIS only group, while N3%, lowest nocturnal oxygen saturation (LSaO 2) were lower (all P<0.05). There was no statistical difference in the distribution of cerebral apoplexy lesions (cortex, subcortical, brainstem, cerebellum) between the two groups, but the proportion of patients with multifocal cerebral apoplexy in the OSAHS group was higher ( P=0.032). There was no statistical difference in NIHSS score on admission between the two groups, but the neutrophil/lymphocyte ratio (NLR) score ( P=0.004) and mRS score on discharge ( P=0.010) of the OSAHS group were significantly higher than those in the AIS only group. There were 74 patients in the good prognosis group and 38 in the poor prognosis group. The analysis showed that the NIHSS and NLR scores of the poor prognosis group were higher than the good prognosis group, admission NIHSS score was a risk factor for poor prognosis, all P<0.01. Conclusions:AIS patients complicated with OSAHS are characterized by disordered sleep structure, more severe nocturnal hypoxia, higher risk of developing multiple lesions, poor neurological function recovery at discharge, and high inflammatory index of NLR. Among them, patients with poor prognosis have poorer sleep efficiency, and high admission NIHSS score is a risk factor for poor prognosis.
RESUMO
Objective To investigate the clinical efficiency of branch artery of the sural medial gastrocnemius muscle flap combine with sural nerve nutritional vessel axial.Methods From February 2006to March 2010,according to the position and size of the soft tissue defects,the muscle flap combined with branch artery of the sural medial gastrocnemius and sural nerve nutritional vessel axial were desingned and obtained to repair 7 cases of sofi tissue defects of the upper-region of the tibial.The flap size ranged from 8.0 cm × 8.0 cm to 12.0 cm × 10.0 cm.The vessel pedicle of branches ranged from 1.8-3.0 cm.The distribution of the vessel pedicle of branches ranged from 10.0-17.0 cm on the distant popliteal fossa,and ranged from 2.0-5.0 cm on the back of medial line.Results The outline and function were satisfactory during 6-15 months follow-up.Conclusion The blood supply of this flap is reliable without sacrifice of major arteries.Flap elevation is easy.It can transfer to a long distance and can repair large skin defects.It is very useful in repairing upper-region of the tibial large soft tissue defect.
