Background: Chronic venous ulcers are a serious problem for both patients and physicians. The CEAP classification(clinical manifestations(C), etiologic factors(E), anatomic distribution of disease(A), and underlying pathophysiologic findings(P)) for chronic venous disorders(CVD) was developed in 1994. Published papers on CVD use all or part of the CEAP. Micropunch grafts, which are a variation of skin grafts, have been used with great success in plastic surgery for both esthetic and reconstructive purposes. This study aimed to assess the outcomes of micropunch grafting in the treatment of chronic refractory venous ***: Patients with chronic venous ulcers who did not respond to conservative treatment for more than 6months were included in the study. All patients underwent ulcer coverage by micropunch skin grafts using a micrometer. The patients were discharged on the same day as the surgery. Micropunch skin grafts were manually counted per square centimeter intraoperatively and during follow-up using Dermlite DermatoschopeTM II Pro *** satisfaction was assessed by using a ***: Twenty patients underwent the surgery. Most of the patients were middle-aged males. The ulcers were predominantly small-and medium-sized. The mean operation time was 167.00 ± 86.01 min. After 6 months, the survival rate of the planted micrografts was 84%. Three ulcers had graft loss and two patients had an infection at the ulcer site, which was managed conservatively. The patients were followed-up for 14 ***: Micropunch grafting is a useful and convenient method for the treatment of difficult venous ulcers and can be performed on an outpatient basis.

This article focuses on the application of coupling both river dynamic and river diffusive modeling techniques that can be used with distributed water balance model. In an upstream watershed, both overland and river diffusive flows are routed by diffusive wave approximation of the free surface flow equations. In river downstream reaches, the river dynamic flow is routed by one-dimensional dynamic wave equations （full dynamic St. Venant equations with lateral flow）. The developed model is applied in a part of Arakawa River basin, Kanto area, Japan. The geographic data of river cross sections could be accurately represented by an 11-point cross-section approximation. The effects of both the grid size and lateral flow on the simulated results of the river dynamic flow model were studied. The grid size should be greater than the average width of the river cross-sections. The lateral flow from small drainage systems has significant effects on the simulated results using the river dynamic flow model. The simulated results show good and acceptable agreements with the observed flow discharges and water depths. Both the river discharge and water depth at any location of river network of compound channels with one/two complex floodplains could be correctly estimated.
