LITA-based Y composite graft, showed satisfactory clinical outcomes and patency whereas modifications of RITA-based composite graft had the lowest patency and 5-year survival rates. Therefore, when using RITA-based composite graft, other options should be considered before proceeding atypical configurations.

Purpose: To investigate the impact of preoperative underlying hypertension (HTN) and body mass index (BMI) on oncologic outcomes in patients with upper tract urothelial carcinoma (UTUC) who underwent radical nephroureterectomy (RNUx). Materials and Methods: From May 2003 to December 2018, 453 UTUC patients who underwent RNUx at a single institution were enrolled in the study. All patients were divided into 2 groups according to preoperative HTN and BMI (cutoff 24 kg/m 2 ) and perioperative param

Malignant fibrous histiocytoma (MFH) is the most common soft tissue sarcoma. It is regarded as an undifferentiated pleomorphic sarcoma with an unproven histogenesis. It most commonly occurs in the skeletal muscles of the extremities or the retroperitoneum of adults. It often metastasizes to the lungs, lymph nodes, bones and liver, but rarely to the skin. We report here a case of malignant fibrous histiocytoma that metastasized to the skin.

Objective: Preoperative autologous donation has been shown to be a highly effective measure in reducing homologous blood use during cardiac operations in human. However, there is no previous animal studies that showed the effectiveness of the autologous transfusion. The aim of our study was to establish and prove the effective strategies of autologous blood donation and transfusion in a porcine model of cardiopulmonary bypass (CPB) which can be applied in preclinical study. Methods: Autologous b

Syringomas confined to the distal extremities are very rare. A 62-year-old man presented with an 8-month history of multiple, light brown, flat-topped papules on both forearms and the dorsa of the hands. Histopathologic examination showed multiple dilated eccrine ducts lined by two rows of epithelial cells. There has currently been less than 10 reported cases of syringoma confined to both forearms and the dorsa of the hands in the world medical literature.

Background: Lipomas are benign neoplasms composed of mature fat cells. Current treatments are invasive and carry the risk of scarring. For this reason, phosphatidylcholine (PPC) formula has been widely used to treat areas of localized fat accumulation. However, there are few reports on injection lipolysis with injection of PPC formula. Objective: The purpose of this study was to investigate whether injection lipolysis with PPC formula is an effective therapeutic option for patients with lipoma.

VVSE significantly reduced venous reflux time across both superficial and deep veins, improving patient-reported symptoms compared with lifestyle modifications alone. The beneficial effects were consistent across diverse patient subgroups and particularly noteworthy in deep venous insufficiency.
