PURPOSE To create a porcine hemodialysis access model that reliably reproduces intimal hyperplasia (IH) of the outflow vein similar to that which causes access failure in human patients undergoing dialysis treatments. MATERIALS AND METHODS Surgical technique for creation of side-to-side iliac-artery-to-ipsilateral-iliac-vein (IAV) native fistulas and IAV(More)
OBJECTIVES Patients who develop metastatic disease from soft tissue sarcoma have a poor prognosis. The purpose of this study was to identify metastatic survival rates and identify prognostic variables that predict for these outcomes. METHODS Between 2000 and 2010, 182 patients with stage I to IV primary soft tissue sarcomas of the extremity and trunk were(More)
PURPOSE To evaluate the role of intercellular adhesion molecule 1 (ICAM-1) in cutaneous leukocyte trapping in venous disease, we used our rodent model of venous hypertension (VH). MATERIALS AND METHODS VH was created in adult rats by ligation of the inferior vena cava, bilateral common iliac veins, and bilateral common femoral veins. In the Phase I(More)
A 23-year-old female with Ewing's Sarcoma underwent tibial resection and skeletal reconstruction using proximal tibial allograft prosthetic reconstruction with distal femur endoprosthetic reconstruction and rotating hinge. Human acellular dermal matrix, (Alloderm, LifeCell, Branchburg, NJ, USA), was used to wrap the skeletal reconstruction. Soft tissue(More)
BACKGROUND Neoadjuvant radiotherapy (NRT) is an effective strategy to treat soft tissue sarcomas (STS). However, the role of neoadjuvant chemoradiotherapy (NCRT) remains to be determined. METHODS From May 1999 to July 2010, 112 patients with localized STS of the extremity and trunk who were treated with NRT or NCRT followed by surgery were retrospectively(More)
BACKGROUND Neoadjuvant therapy with radiation +/- chemotherapy is an accepted management for soft tissue sarcomas (STS). The incidence of post-therapy lymphedema is around 30%. The purpose of this study was to identify variables that predict for post-therapy lymphedema. METHODS From 2000 to 2010, 132 patients with STS were treated with neoadjuvant(More)
PURPOSE Adjuvant high-dose-rate brachytherapy (HDRBT) offers advantages over low dose rate brachytherapy (LDRBT), although there are little data on local tumor control and treatment related toxicity. We report outcome in patients with primary, recurrent, and metastatic extremity and superficial trunk soft tissue sarcoma. MATERIAL AND METHODS Eleven(More)
A 47-year-old female with a locally advanced urologic malignancy previously managed with resection, diversion, and postoperative radiation therapy presented for management of her recurrent cancer that had eroded through the soft tissues of the left inner thigh and vulva. On all staging studies the tumor involved the left common femoral artery, and vein,(More)
Perforator flaps are routinely used in upper- and lower-extremity reconstruction. Increased usage of these flaps as well as their intraoperative thinning has been described; however, there are limited reports of thinning in the postoperative period. From 2005 to 2010, thinning procedures were performed on 11 patients with 11 flaps. There were six males and(More)
