Popliteal artery entrapment syndrome (PAES) is a non-artherosclerotic cause of claudication and acute ischemia of the legs in young athletic individuals. It is classified in terms of the abnormal anatomical relationship between the popliteal artery and surrounding structures. All types of PAES have the same pathophysiology. Repetitive arterial compression(More)
PURPOSE At present, a human epidermal growth factor receptor 2 (HER2)-based concept of tumor biology has been established, and trastuzumab (Herceptin®; Genentech/Roche, San Francisco, CA, USA), a monoclonal humanized antibody directed against HER2, is a pivotal agent for the management of HER2 positive (HER2+) metastatic breast cancer. It is also known that(More)
Cyanoacrylate (CA) is most widely used as a medical and commercial tissue adhesive because of easier wound closure, good cosmetic results and little discomfort. But, CA-based tissue adhesives have some limitations including the release of cytotoxic chemicals during biodegradation. In previous study, we made prepolymerized allyl 2-CA (PACA) based tissue(More)
OBJECTIVE The purpose of this study was to evaluate the fistulographic features of malfunctioning axillary loop-configured arteriovenous grafts and the efficacy of percutaneous interventions in failed axillary loop-configured arteriovenous grafts. MATERIALS AND METHODS Ten patients with axillary loop-configured arteriovenous grafts were referred for(More)
BACKGROUND Extracorporeal circulation (ECC) can induce alterations in blood viscoelasticity and cause red blood cell (RBC) aggregation. In this study, the authors evaluated the effects of pump flow pulsatility on blood viscoelasticity and RBC aggregation. METHODS Mongrel dogs were randomly assigned to two groups: a nonpulsatile pump group (n=6) or a(More)
BACKGROUND Conventional stripping is considered to be the standard procedure for great saphenous vein (GSV) varicosities, but many other alternative treatments such as cryostripping, endovenous laser therapy (EVLT), radio-frequency ablation, and ultrasound-guided foam sclerotherapy have been developed. Among them, both cryostripping and laser therapy have(More)
Chylothorax is a rare postoperative complication of a thoracic surgical procedure. Here, we report a case of chylothorax after thoracic endovascular aortic repair with debranching for the distal arch aneurysm of the aorta. First, the patient was treated by a medical method (nil per os, fat-free diet, and octreotide), but this method failed. The patient(More)
BACKGROUND A closed pleural biopsy is commonly performed for diagnosing patients exhibiting pleural effusion if prior thoracentesis is not diagnostic. However, the diagnostic yield of such biopsies is unsatisfactory. Instead, a thoracoscopic pleural biopsy is more useful and less painful. METHODS We compared the diagnostic yield of needle thoracoscopic(More)
Understanding of relationship between pore properties and tissue regeneration of expanded polytetrafluoroethylene (ePTFE) is important in design of vascular tissue engineering. Tissue regeneration into a micron scale pore of the ePTFE wall was investigated by employing techniques of superficial surface modification of ePTFE, fabrication of the hybrid(More)
In chest wall reconstruction after wide chest wall resection, the use of a musculocutaneous flap or prosthetic materials is inevitable for maintaining thoracic movement and a closed pleural cavity. We report a case of a 63-year-old male with a large invasive thymic carcinoma in the anterior mediastinum. The mass measured 6.8 cm and involved the sternum,(More)
