RESUMEN
From May 2009 to February 2012, five patients with traumatic lower limb arteriovenous fistula were admitted in our department .Four patients underwent endovascular stent grafting , and one patient was given fistula indwelling , deep femoral artery-superficial femoral artery end to side anastomosis , and femoral artery-superficial femoral artery artificial vescular grafting .Four patients were cured, which were followed for 3, 5, 3, and 3 years, respectively, without recurrence.One patient with endovascular stent grafting failed to isolate the fistula effectively and a second stent grafting failed , too.Endovascular stent grafting is an effective method in the treatment of fistula, with less bleeding, small trauma, and rapid recovery.By using the technology of through the hillsto isolate limb fistula, the covered stent might not be released when the fistula is located at low position and at the same time the left iliac artery bifurcation angle is small .
RESUMEN
Objective To investigate the value of ultrasound integrated backscatter (IBS) in quantitative analysis of in-traluminal thrombus in abdominal aortic aneurysm (AAA).Methods IBS of intraluminal thrombus in 29 patients were measured,including All (average image intensity) and SDI (standard deviation of image intensity).Meanwhile,different echoes and characteristics of IBS in thrombus were compared and pathologic analysis was performed.Results ①Individual All value of homogenous thrombus differed remarkably,SDI value was low.There was no significant difference about All in homogeneous group and adjacent cavity group (P>0.05).All and SDI value in adjacent wall group were higher than those in other groups (P<0.01).②According to pathologic analysis,cellulose contents were abundant in adjacent wall group,but fewer in adjacent cavity group and homogeneous group.Conclusion IBS might be regarded as a sensitive and specific method and a quantitative basis for estimating and predicting the rupture risk of AAA.
RESUMEN
Objective To explore the interaction between serum melatonin and the status of disease and probe the effect factor of serum melatonin change in asthmatic children.Methods Serum melatonin was measured in asthmatic children with 15 cases of mild persistent asthma,15 cases of moderate persistent asthma,15 cases of severe persistent asthma,15 cases of stable asthma and 15 cases of normal subjects by enzyme-linked immunosorbent assay(ELISA).Results The levels of serum melatonin in the 5 groups of mild persistent asthma,moderate presistent asthma,Severe Persistent asthma,Stable asthma,control subject were(22.76?5.16)ng/L,(16.79?3.35)ng/L,(11.54?1.45)ng/L,(22.06?3.36)ng/L,(28.72?4.32)ng/L,respectively.There were significant differences between any of them(Pa
