        Thoracic aortic aneurysms are potentially life-threatening. They are caused by atherosclerosis, most commonly of the descending aorta. Clinical manifestations are due to the compression or erosion of adjacent structures, dissection, or rupture. Thoracic a

        Background: Atrioventricular nodal reentrant tachycardia (AVNRT) is the most common form of supraventricular tachycardia. Radiofrequency cather ablation (RFCA) of the slow pathway can treat AVNRT. Slow pathway ablation is associated with a risk of complete AV block in rare cases. In difficult cases, electrophysiologist should check degrees of artrioventriculr node(AVN) damage during and after ablation. There are several methods of identifying high risk of slow pathway ablation and identifying degree of AVN damage, but sometimes there are not perfect. Adenosine is effective in AVNRT termination by influencing AVN conduction. Use of adenosine can identify change of AVN conduction properties Methods : Adenosine tests were studied in 24 patients (10 men, 14 woman:43.5± 16.6 years) with inducible sustained AVNRT. Adenosine 6㎎ and 12㎎ were injected before and after successful ablation of slow pathway during sinus rhythm. Results : With adenosine 6㎎ injection, AVNRT occurred in 13patients and A-H jump in 15 patients before ablation, whereas AVNRT occurred in no patient and A-H jump in 5 atients after ablation. Adenosine 6㎎ induced AV block beats were significantly increased from 0.4±1.5 to 4.0±4.0 beats by ablation (p<0.05). Adenosine 6㎎ induced longest RR interval was also significantly increased from 876±319 to 1575±852 msec by ablation (p<0.05). And then adenosine 12 ㎎ were injected before and after ablation of slow pathway in 21 patients. AVNTR occurred in 13 versus 0 patient, A-H jump occurred in 16 versus 9 patients. the longest RR interval was 1590±714 versus 4245±3492 msec(p<0.05). Conclusion : After successful RFCA of AVNRT, adenosine increases the number of AV block beats and the longest RR interval significantly. Administration of adenosine during and after ablation can identify severe AV nodal damage which was induced by ablation. Administration of adenosine during and after RFCA enables us to estimate amount of AV nodal damage and it give us information about when to stop the cather ablation. Adenosine can be useful to identify patients with impending heart block during and after ablation of slow pathway.

        BACKGROUND Fatty liver is a common disease characterized by diffuse accumulation of neutral fat(triglycerides) more than 5 percent in liver. Ultrasonography has used to be a diagnostic tool for fatty liver, because of cost-effective and non-invasive study. But the sensitivity and specificity of ultrasonography for diagnosis of fatty liver are variable. Thus, we conducted a retrospective study to investigate correlation between histology and sonographic findings of fatty change in liver. METHODS We collected data from 47 patients who were diagnosed as fatty liver by liver biopsy and ultrasonography from January, 1994 to December, 1997. We compared a sonographic finding with the histologic grade of fatty liver and analysed the data retrospectively by SAS program. RESULTS Major cause of fatty liver is alcohol. The mean consumption of alcohol during 1 day is 64.1 gram, and the mean duration of alcohol drinking is 16.5 years. Degree of fatty infiltration in ultrasonography was significantly correlated with degree of fatty accumulation of liver(p=0.001). But, though it was diagnosed as normal by ultrasonography, 19.1% of total patients was fatty liver by needle biopsy. CONCLUSION We think that liver biopsy is needed for further management and follow-up, if liver function test is abnormal, though the finding of ultrasonography is normal.
