OBJECTIVE Endovascular aneurysm repair (EVAR) is considered the standard therapy for most patients with abdominal aortic aneurysm (AAA). Endoleak is a well-known EVAR-related complication that requires long-term follow-up. However, patient follow-up is often challenging outside clinical trials. We sought to evaluate the incidence and the effect of delayed(More)
The artery and vein of the transplanted kidney are generally anastomosed to the external iliac artery and vein, respectively. Therefore, in open abdominal artery aneurysm (AAA) repair in renal transplant patients, kidney ischemia due to a proximal aortic clamp is a serious problem. We successfully performed endovascular aneurysm repair (EVAR) of AAA without(More)
PURPOSE Ureteroscopic stone removal is frequently used to remove ureteral stones. Mucosal edema and bleeding are the two most important obstacles to a successful operation. This study analyzed relationships between unenhanced computed tomography (UECT) findings and ureteroscopic findings to determine whether ureteroscopic results could be predicted(More)
The mean platelet volume (MPV) is a laboratory marker associated with platelet function and activity. Increased MPV in thromboembolic disease is considered an important risk factor. The aim of this study was to compare the MPV and MPV/platelet count (MPV/P) ratio between deep vein thrombosis (DVT) and control subjects. We retrospectively reviewed the(More)
BACKGROUND Adventitial cystic disease (ACD) is an unusual arteriopathy; case reports and small series constitute the available literature regarding treatment. We sought to examine the presentation, contemporary management, and long-term outcomes using a multi-institutional database. METHODS Using a standardized database, 14 institutions retrospectively(More)
PURPOSE Increased saphenous vein diameter is a common consequence of saphenous vein reflux. Until now, there have been no reports about the correlation between diameter and reflux of saphenous vein in Korea. The aim of this study was to investigate the correlation between saphenous vein reflux and diameter changes. METHODS From April 2009 to August 2012,(More)
PURPOSE It is important to know the normal diameter of artery throughout the body so that clinicians are able to determine when an artery becomes aneurysmal. However, there are no previous studies on the normal diameter of arteries in the general Korean population. The purpose of this article is to determine the normal reference diameters of the abdominal(More)
PURPOSE Radiofrequency ablation (RFA) is a widely accepted to treat the varicose vein. However, outcome studies for occlusion rate and patterns of the saphenous vein after RFA are scarce. The purpose of our study is to report the results of RFA in patients with varicose vein. METHODS We retrospectively reviewed the clinical outcomes after RFA using(More)
We report a case of infarction of lesser omental fat in a 30-year-old woman who presented with epigastric pain. Sonography revealed a painful echogenic mass in the epigastrium that could not be separated from the adjacent hyperechoic pancreas and mimicked an exophytic pancreatic tumor. On CT, the mass was identified as an inflammatory lipomatous mass in the(More)
UNLABELLED The objective of this paper is to introduce the schematic protocol of radiofrequency (RF) ablation for the treatment of varicose veins. INDICATION anatomic or pathophysiologic indication includes venous diameter within 2-20 mm, reflux time ≥0.5 seconds and distance from the skin ≥5 mm or subfascial location. Access: it is recommended to access(More)
