This study investigated the appropriate tourniquet pressure (TP) and duration of tourniquet application for venipuncture by calculating the venous cross-section (VCS) area on ultrasonography. Twenty healthy volunteers without cardiovascular risk factors were enrolled in this study. A target vein (either a cephalic or median cubital vein) was selected on(More)
Chronic expanding hematoma (CEH) is a relatively rare complication of trauma or surgery. We report a patient with CEH as a late complication of abdominoplasty. A 58-year-old woman underwent conventional abdominoplasty and thereafter refused to use a compression binder, citing discomfort. One month postoperatively, she presented with a gradually enlarging,(More)
This study aimed to investigate relations between ease of venous palpation and various venous factors, and to elucidate characteristics of hardly palpable veins. Healthy adult volunteers (n = 110) were enrolled. The ease of venous palpation was scored from 0: impalpable to 3: well palpable. Venous factors, namely venous depth, elevation, area and minimal(More)
Image-guided radiation therapy (IGRT) is increasingly being used in modern radiation therapy, and it is now possible to verify a patient's position using kilo-voltage cone-beam computed tomography (kV-CBCT). However, if kV-CBCT is used frequently, the dose absorbed by the body cannot be disregarded. A number of studies have been made on the absorbed dose of(More)
