1. Brachiocephalic Vein and Superior Vena Cava Reconstruction with a Superficial Femoral Vein Graft
Abstract Superior vena cava syndrome (SVCS) is an entity that has become more frequent due to the increasing use of indwelling central venous catheters. Surgical management is considered in patients with extensive venous thrombosis and when endovascular therapy is not feasible. The use of superficial femoral vein is an excellent technique for reconstruction

2. The role of vein grafts in reconstructive head and neck microsurgery
Abstract Objective: Free tissue transfer is widely used for head and neck reconstruction. In certain circumstances, vein grafting is required to elongate free flap pedicles to connect them to appropriate recipient vessels. Because of controversy regarding the use of interposition vein grafts in free tissue reconstruction, this paper reports vein graft indic

3. Short-term outcome of Polytetrafluoroethylene Membrane Valve versus Transannular Pericardial patch Reconstruction of Right Ventricular Outflow Tract in Tetralogy of Fallot : a Randomized Controlled Trial
Abstract Introduction: Reconstruction of right ventricular outflow tract during primary repair of tetralogy of Fallot often requires the placement of a transannular patch which results in pulmonary regurgitation (PR). We compared the short-term outcomes of bicuspid polytetrafluoroethylene membrane valve versus transannular pericardial patch reconstruction o

4. Preliminary Study on Functional and Aesthetic Reconstruction by Using a Small Artery-only Free Medial Flap of the Second Toe for Fingertip Injuries
OBJECTIVES: This study was designed to introduce the feasibility of fingertip reconstruction by using a free medial flap of the second toe without vein anastomosis. METHODS: In total, 8 patients with fingertip injuries were treated successfully with this method. Patients who underwent reconstruction from September 2016 to October 2017 in our hospital with

5. Experimental study of histological changes in vascular loops according to the duration of the postoperative period: Application in reconstructive microsurgery
OBJECTIVES: To analyze the histological changes observed in venous grafts subjected to arterial blood flow as a function of the duration of the postoperative period to optimize their use in free flap reconstructions. METHOD: Twenty-five rats (7 females and 18 males) underwent surgery. Surgeries were performed on one animal per week. Five weeks after the fi

6. Penile reconstruction using mesenchymal stem cells
PURPOSE: To compare the reconstruction of corpus cavernosum segments when seeded with mesenchymal stem cells and when stem cells are infused intravenously.METHODS: Sixteen New Zealand rabbits were submitted to reconstruction of the corpus cavernosum and distributed in Group A - decellularized matrices, Group B - decellularized matrices seeded with mesenchyma

7. Estudo do biopolÃmero de cana-de-aÃÃcar como remendo em veias femorais de cÃes
IntroduÃÃo: A partir da dÃcada de cinqÃenta numerosos substitutos vasculares foram desenvolvidos a fim de atender as necessidades do cirurgiÃo nas correÃÃes de patologias arteriais e venosas. O melhor substituto vascular utilizado nas cirurgias de revascularizaÃÃo à a safena magna , que nem sempre esta disponÃvel para pronta utilizaÃÃo. Conseque

8. Estudo prospectivo aleatorizado comparando a eficiência clínica dos métodos convencional ou piggyback na drenagem venosa do fígado transplantado / Prospective randomized trial comparing the clinical efficiency of conventional versus piggyback method in venous drainage of the transplanted liver
The aim of this study is to compare the clinical efficiency of hepatic venous outflow reconstruction in conventional and piggyback method of liver transplantation (LTx). The efficacy of the different types of reconstruction of venous drainage in the piggyback liver transplantation was analyzed by a second purpose. Thirty two patients submitted to LTx by conv

9. Estudo morfométrico comparando duas alternativas de reconstrução da via de efluxo venoso do enxerto no método piggyback de transplante de fígado / Morphometric study comparing two methods of hepatic venous outflow reconstruction in piggyback liver transplantation
INTRODUCTION: In piggyback liver transplantation (LT), partial clamping of the recipient inferior vena cava (IVC) preserves the venous return of the lower extremities during the anhepatic phase precluding the use of venovenous bypass. The incidence of hepatic venous outflow obstruction after piggyback LT varies according to the type of venous reconstruction.

10. Anatomic study of the anterolateral thigh flap / "Estudo anatômico do retalho perfurante ântero-lateral da coxa"
INTRODUCTION: The anterolateral thigh flap is based on the perforator vessels of the descending branch of the lateral circumflex femoral artery. This flap has very interesting characteristics for the reconstructive surgery, like the small thickness, long pedicle and excellent donor site. On the other hand, there are many controversial data on the literature

11. Utilização da veia esplênica para restabelecer o fluxo sangüíneo mesentérico-porta após ressecção de veia mesentérica superior durante duodenopancreatectomia
Superior mesenteric vein invasion has historically been considered a contraindication for pancreatic cancer resection. Several studies have shown that in selected cases vascular resection can be performed safely. Many techniques have been used to reconstruct the venous flow. We describe one case of mesenteric superior vein resection and reconstrution of mese

12. Replacement of the Left Common Iliac Vein with a Custom-Made Bovine Pericardium Tubular Graft
To date, venous reconstruction has not been as successful as arterial reconstruction. Prosthetic materials used as venous substitutes produce much lower patency rates with a higher incidence of early thrombosis than those used as arterial substitutes.
