RESUMEN
Objective To discuss the meanings and methods of the screening, diagnosis and treatment of the left subclavian artery stenosis before the coronary artery bypass grafting (CABG). Methods A total of 612 patients intend to perform coronary artery bypass grafting in Tianjin Thoracic Hospital,and who were with severe stenosis or occlusion with left subclavian artery were screened by non invasive arteriosclerosis before operation. The diagnosis was confirmed by computerized tomography angiography(CTA),then the stenting angioplasty to the left subclavian artery was performed.The off-pump bypass surgery with the left internal thoracic artery(LITA)-left anterior descending artery (LAD) bypass was performed one week after operation.Results The CTA and digital subtraction angiography(DSA)confirmed the results of the left subclavian stenosis according to the non-invasive artery testing.All the 5 patients were performed with the stenting angioplasty to the left subclavian artery successfully,and the residual stenosis rate was<10%.The clinical symptoms were markedly improved after operations in all symptomatic patients,and the systolic pressure difference was<20 mmHg in two upper extremities.The blood flow was enough in LITA during the LITA-LAD bypass.The angina pectoris was improved after the operation. No coronary-subclavian artery steal phenomenon occurred. Neither stroke, myocardial infraction nor death occurred during perioperative period.All the patients were followed up for a time of 6-12 months,and the average time was about 10 months.No posterior circulation,upper limbs or myocardial ischemia occurred,and the systolic pressure difference was<20 mmHg in two upper extremities.Conclusion The non-invasion testing is of unique value in the screening of the left subclavian artery stenosis.
RESUMEN
Objective To understand the status of abortion and risk factors among floating women of childbearing age and to provide reference for further improvement of induced abortion services in this population.Methods Data on demography,working,and living conditions as well as the use of contraceptive among 4687 persons from a reproductive health survey regarding floating population in five cities in 2005,were involved,while multivariate logistic regression model was used to find out the relationship.Results The risks of abortion among the younger than 30 age group and the 30-39 age groups were 2.21 times (95％CI:1.47-3.34) and 2.38 times (95％CI:1.53-3.70) of the 40-49 age group,respectively.The higher education degree these women had,the higher the risk of abortion was.The risks of abortion among groups having elementary,junior high,senior high school and above,were 2.15 times (95％CI:1.15-4.03),2.47 times (95％CI:1.33-4.57) and 2.61 times (95％CI:1.34-5.11) of those illiterate women.Those having working experience of 2-4 years,5 years or above at the places where the survey was completed,the risks were 2.62 times (95％CI:1.83-3.76)and 7.78 times (95％CI:5.63-10.75) of the less than 2-year-experienced group.The abortion risk of floating women at childbearing age who were living together with their spouses was 1.49 (95％CI:1.05-2.11) times of those women who were not.Conclusion The demographic and lifestyle as well as working features of floating women at childbearing age might increase their risk of abortion.Providing health education regarding these risk factors on the floating women at childbearing age could effectively reduce and prevent the risk of abortion risk among them.
