Endovascular Abdominal Aortic Aneurysmal Repair:A Korean Perspective
안철민,최동훈,심원흠 대한심장학회 2007 Korean Circulation Journal Vol.37 No.10
Endovascular aneurysm repair (EVAR) was initially introduced as a less invasive alternative to conventional open repair.EVAR was subsequently adopted as a treatment option for abdominal aortic aneurysm. In Korea, open repair is more widelyavailable than EVAR, although EVAR can be performed in several hospitals. Due to the rapidly aging population in Korea,there has been a shift from private healthcare to government-regulated universal coverage and EVAR may be a more feasibleoption for cardiovascular interventionalists in these days. The improvement of EVAR was rapidly attained by many pioneersfor the last two decades. Although issues such as indications and durability of EVAR remain to be elucidated, its applicationcan be extended further of milder invasiveness-related effects on comorbidities and less discomfort to patients. Aortic stentgraftinghas been performed for various aortoiliac pathologies over the last 13 years at our cardiovascular center.1-3) Thisarticle presents a comprehensive review on EVAR by focusing on the clinical trials, indications, complications, and expertisein decision making for EVAR.

Background and Objectives : There are so many methods to investigate the causes of voice disorders. However, they were almost invasive or non-physiologic methods. And none of them showed the laryngeal movements. Phonation pharyngogram is non-invasive method to see the laryngeal movement directly. Authors studied to evaluate the availability of phonation pharyngogram in laryngeal nodule. Materials and Methods : 30 laryngeal nodules and 10 control groups were evaluated. Acoustic analysis and maximum phonation time were measured and pharyngogram was taken during sustaining /a/ phonation immediately after swallowing the barium. We measured the width of hypopharyngeal wall, shape of hypopharyngeal wall and pyriform sinus apex, level difference between both true vocal folds, angle of subglottis, location of true vocal folds, elevated distance of vocal folds and shape of c-spine. Results : Jitter, Shimmer of laryngeal nodule were higher than control group and maximum phonation time was shorter in laryngeal nodule. There was a significance in width of hypopharyngeal wall, shape of pyriform sinus apex, level difference between both true vocal folds, elevated distance of vocal folds and shape of c-spine. Conclusions : Authors knew that there were differences when we used the phonation pharyngogram between normal group and laryngeal nodule group.

Incomplete glottic closure of vocal cord atrophy is the common cause of dysphonia. Patients with vocal cord atrophy have complaints such as dysphonia, vocal fatigue, abnormal sensation in the throat, laryngeal pain, cough or sputum like functional voice disorders. Many investigators could not confirm the pathologic laryngeal structure because of their minute pathology. But recent advancements of laryngeal examinations made the many clinicians to detect minimal laryngeal pathology and to have mind the treatment for the vocal cord atrophy. But the results were less effective than their thoughts, the reasons of ineffectiveness were not known well. Authors have found the Hyperfunctional movement of the supraglottis during phonation before and after thyroplasty type I for vocal cord atrophy. Then we have applied the combined modality treatment with thyroplaty type I and voice therapy for relieve of hypefunctional movement of the supraglottis. These options have had more imporved results.
