BACKGROUND: Fat grafting is a commonly performed procedure not only for augmenting the soft tissue but also for regeneration in esthetic and reconstructive plastic surgery.However, unpredictable fat survival rate because of high resorption rate is remained as the main problem. The purpose of this study was to investigate the effect of pretreatment of the recipient site to the fat survival using fractional carbon dioxide (CO2) laser. METHODS: The rats were divided to 2 groups...

In order to improve property of bacterial nano-cellulose (BNC) to achieve the requirements of clinical application as small caliber vascular grafts, chitosan (CH) was deposited into the fibril network of the BNC tubes fabricated in unique Double-Silicone-Tube bioreactors. Heparin (Hep) was then chemically grafted into the BNC-based tubes using EDC/NHS crosslinking to improve performance of anticoagulation and endothelialization. Physicochemical and mechanical property, blood compatibility, and cytocompatibility were compared before and after compositing...

Vascular xenografts are widely used in cardiovascular surgery as an alternative to autologous vessels and vascular allografts. Calcification is one of the main drawbacks of vascular grafts, especially among young patients and children. Among different anticalcification approaches, chitosan emerges as a highly promising candidate due to its versatility, natural origin, and biocompatibility. We investigated the anticalcification efficacy of globular chitosan ("Chitozol") as it demonstrated the improved rate of water solubility as compared with conventional linear macromolecules of chitosan...

OBJECTIVES: To develop a model for predicting long-term survival following coronary artery bypass graft surgery. METHODS: This study included 46 573 patients from the Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZCTS) registry, who underwent isolated coronary artery bypass graft surgery between 2001 and 2014. Data were randomly split into development (23 282) and validation (23 291) samples. Cox regression models were fitted separately, using the important preoperative variables, for 4 'time intervals' (31-90 days, 91-365 days, 1-3 years and >3 years), with optimal predictors selected using the bootstrap bagging technique...

Bladder reconstruction remains challenging for urological surgery due to lack of suitable regenerative scaffolds. In a previous study, we had used a collagen-binding basic fibroblast growth factor (CBD-bFGF) to bind bFGF to the collagen scaffold, which could promote bladder regeneration in rats. However, the limited graft size in rodent models cannot provide enough evidence to demonstrate the repair capabilities of this method for severely damaged bladders in humans or large animals. In this study, the CBD-bFGF was used to activate a bladder acellular matrix (BAM) scaffold, and the CBD-bFGF/BAM functional scaffold was assessed in a canine model with a large segment defect (half of the entire bladder was resected)...

INTRODUCTION: Due to the current organ shortage, nearly 20% of patients die waiting for a liver transplant (LT). The average donor age is on the rise, and grafts from elderly donors are offered as extended criteria grafts. METHODS: This is a meta-analysis comparing the outcome differences of adult patients undergoing LT using grafts from <70-year-old donors versus >70-year-old donors. The primary end-points were graft and patient survival. Secondary outcomes were biliary and vascular complications as well as graft function...

BACKGROUND: Vascular complications following liver transplantation (LT) may result from technical deficiencies. Intraoperative diagnosis remains challenging but can prevent serious delayed complications. Intraoperative Doppler ultrasonography (IOUS) represents the gold standard for imaging, although it requires radiological skills. Contrast-enhanced ultrasonography has been reported during postoperative assessments, but never intraoperatively (CE-IOUS). The aim of this study was to assess the feasibility of routine CE-IOUS, to evaluate its impact on surgical strategy and its usefulness...

BACKGROUND: Fat grafting is a popular soft tissue filler method; however, its results are variable and technique-dependent. Macrophages are present in fat grafts and closely associated with tissue regeneration. We hypothesized that activation/depletion of early macrophages in transferred fat improves/impairs fat graft survival. METHODS: Mouse inguinal fat (~150 mg) was transferred autologously. Fat grafting was first performed without other manipulations to obtain baseline information...

Hepatocellular carcinoma (HCC) recurrence rate after liver transplantation (LT) is still up to 15-20%, despite a careful selection of candidates and optimization of the management within the waiting list. To reduce tumour recurrence, the currently adopted post-transplant strategies are based on the administration of a tailored immunosuppression (IS) regimen. Drug-induced depression of the immune system is essential in preventing graft rejection, however has a well-established association with oncogenesis. The immune system has a key role as a defending mechanism against cancer development, preventing vascular invasion and metastasis...

Neck trauma is the leading cause of death mainly in younger persons posing to surgeons the dilemma whether to proceed with reconstruction of vascular injuries either in the presence of coma or in severe neurological deficit. Vascular injuries in zone II predominate over the other injuries located in zones I/III of the neck. Conventional open repair of carotid injuries with primary closure or interposition grafting is always recommended due to the effective long-term results for penetrating injuries or for patients unfit for endovascular intervention...

Objective: To evaluate in vivo patency rates of silk fibroin (SF) vascular grafts and resulting histological reactions in a canine model. Methods: To generate 3.5-mm inner diameter vessels, a combination of plaited silk fibers were wound with cocoon filaments and subsequently coated with an SF solution. The resulting SF grafts (n=35) were implanted into the carotid arteries of male beagles (age, 1-2 years; body weight: 9.0-10.5 kg). Expanded polytetrafluoroethylene (4-mm inner diameter, ePTFE) grafts (n=5) were used as controls...

Open surgery for a type Ib endoleak after thoracic endovascular aortic repair is associated with some knacks and pitfalls, particularly in cases wherein the distal edge of a stent graft is located at just supraceliac aorta and the renovisceral segment and infrarenal aorta do not require surgical intervention. Here we describe the invaginated graft insertion technique to provide an easy and secure anastomosis in such clinical situations. This procedure may be feasible for anastomosis between a prosthetic vascular graft and a previously deployed stent graft when the location of the anastomosis is distant from the surface of the skin incision with a narrow and limited surgical view...

Autogenous vein grafts remain the gold standard conduit for arterial bypass, particularly for the treatment of critical limb ischemia. Vein graft adaptation to the arterial environment, i.e., adequate dilation and wall thickening, contributes to the superior performance of vein grafts. However, abnormal venous wall remodeling with excessive neointimal hyperplasia commonly causes vein graft failure. Since the PREVENT trials failed to improve vein graft outcomes, new strategies focus on the adaptive response of the venous endothelial cells to the post-surgical arterial environment...

The treatment of patients with severe coronary and peripheral artery disease represents a significant clinical need, especially for those patients that require a bypass graft and do not have viable veins for autologous grafting. Tissue engineering is being investigated to generate an alternative graft. While tissue engineering requires surgical intervention, the release of pharmacological agents is also an important part of many tissue engineering strategies. Delivery of these agents offers the potential to overcome the major concerns for graft patency and viability...
