Endoscopic Surgery versus External Ventricular Drainage Surgery for Severe Intraventricular Hemorrhage.

The efficacy and applied value of endoscopic hematoma evacuation vs. external ventricular drainage (EVD) in the treatment of severe ventricular hemorrhage (IVH) were explored and compared. From Jan. 2015 to Dec. 2016, the clinical data of 42 cases of IVH were retrospectively analyzed, including 18 patients undergoing endoscopic hematoma evacuation (group A), and 24 patients receiving EVD (group B). The hematoma clearance rate was calculated by 3D Slicer software, and complications and outcomes were compared between the two groups. There were no significant differences in age, sex and Graeb score between groups A and B (P>0.05). The hematoma clearance rate was 70.81%±27.64% in group A and 48.72%±36.58% in group B with a statistically significant difference (P<0.05). The operative time in groups A and B was 72.45±25.26 min and 28.54±15.27 min, respectively (P<0.05). The Glasgow Coma Scale (GCS) score increased from 9.28±2.72 at baseline to 11.83±2.91 at 1 week postoperatively in group A, and from 8.25±2.62 at baseline to 10.79±4.12 at 1 week postoperatively in group B (P<0.05). The length of hospital stay was 12.67±5.97 days in group A and 17.33±8.91 days in group B with a statistically significant difference (P<0.05). The GOS scores at 6 months after surgery were 3.83±1.12 in group A, and 2.75±1.23 in group B (P<0.05). These results suggested that endoscopic hematoma evacuation has an advantage of a higher hematoma clearance rate, fewer complications and better outcomes in the treatment of severe IVH, indicating it is a safe, effective and promising approach for severe IVH.

[Comparison of the exposure rates of risk factors and inducing factors of acute myocardial infarction between younger and aged adults].

OBJECTIVE: To study the clinical characteristics of acute myocardial infarction (AMI) among younger adults and to explore the possible mechanisms of early myocardial infarction, combined with the newly discovered risk factors of coronary heart disease. METHODS: Data on comparative analysis to the exposure rates of the risk factors and inducing factors of non-CAD patients with two groups of AMI patients including younger adults group (< or =40 years old) and aged adults group (> or =50 years old). Coronary angiography was applied. RESULTS: There were differences noticed between the frequencies of risk factors of the two AMI groups. In younger adults group the exposure rates of smoking, hyperlipidemia, positive family history, C-reactive protein (CRP) and fibrinogen were markedly higher, while in elderly group the exposure rates of hypertension, smoking, hyperlipidemia, diabetes, CRP, fibrinogen and homocysteine (HCY) were markedly higher (P < 0.05). Although the clustering status of risk factors of the younger adult group was not higher than that of the elderly group. There were obvious inducing factors before the patients were attacked by AMI and the inducing factors inclined to cluster, which had obvious dose-reaction relationships with the occurrence of AMI in young people. CONCLUSION: Early AMI of younger adults might relate to the clustering status of inducing factors. The coexistence of several kinds of inducing factors was resulted in the occurrence of AMI of the atherosclerosis (As) and non-As patients by means of myocardial ischemia accumulation effect.
