RESUMO
Objective:To investigate the experience of moderate hypothermia(28℃) using in Stanford A aortic dissection.Methods:A retrospective analysis of 100 patients with Stanford A aortic dissection from January 2012 to March 2014, including 50 cases with deep(25℃) hypothermic circulatory surgery and 50 moderate(28℃) hypothermic circulatory surgery. The operation was performed with ascending aortic replacement, inclusiong aortic arch angioplasty, and stent implantation with descending aorta stent. The difference between the 2 groups during and after the operation was compared.Results:2 cases died in the hypothermia group, and 3 cases died in the deep hypothermia group. There were significant differences( P<0.05) between the middle and low temperature groups in the cooling time, the time of stopping circulation, the time of rewarming, the time of cardiopulmonary bypass, the time of operation, the time of operation, the time of conscious, the time of mechanical ventilation and the first day after the operation( P<0.05), but there was no significant difference between the creatinine and the bilirubin( P>0.05). Conclusion:Under the condition of sufficient cerebral perfusion and spinal cord protection, moderate hypothermia is safe, and it can reduce the operation time and postoperative complications. It has certain clinical significance.
RESUMO
Objective To investigate the curative effect of kelp micro gelation (KGM) for bronchi arterial chemoembolization (BACE) combined with radiofrequency ablation (RFA) for central lung cancer.Methods 60 patients pathologically confirmed as the central lung cancer were enrolled and performed with BACE+KGM after the tumor-feeding artery was confirmed.RFA was performed under local anesthesia 1 month later.1 month,3 months and 6 months after the treatments CT scan was performed to show the changes of the tumor.Tumor markers were detected by blood test 1 month before and after the treatments.Up to the end of this study.Improvements of clinical symptoms and complications were also evaluated.Results Among the 60 patients under the treatment of BACE+KMG+RFA,10 patients had a complete remission(CR),33 patients in partial remission (PR),11 patients in stable (SD) and 6 patients in progress (PD).1 month after the treatments,VEGFA,VEGFB,VEGFC,CEA,CA125 and CA19-9 were significantly decreased,with the overall reactive rate (ORR) of 71.67％,disease control rate (DCR) of 90.00％,18.33％ of no change,10.00 ％ progressing and the 2 year survival rate was 93.33 ％.Conclusion BACE+KMG combined RFA is an effective treatment for central lung cancer with better short-term and long-term effect,improving the life quality and survival time of patients significantly.
