Purpose: From Nov. 2002 to May 2006, eight hundred and seventy-two patients with valvular insufficiency of lower extremity were treated by improved external valvuloplasty and venous laser photocoagulation. This study was to summarize our clinical experience. Methods: Data in 872 patients with primary deep venous valve insufficiency who were performed improved external valvuloplasty and intravenous...
Objective: Study the influence of Hematoporphyrin Monomethyl Ether (HMME) concentration in blood vessel in a rather short time on photodynamic therapy (PDT) microvascular effect by mathematical modeling and animal experiment. Methods: The yields of singlet oxygen in blood vessel in a short time in different animal were simulated by mathematical model, and the yields of singlet oxygen in Leghorn Cocks...
Near infrared (NIR) spectroscopy has been demonstrated as a new means to quantify oxygenation of tissue vasculature, in particular changes in hemoglobin concentrations and oxygen saturation. A novel application such oximetry to monitoring of tumor vascular oxygenation during respiratory interventions will be presented. Our recent results obtained with a one-channel NIR spectrometer observing rat breast...
