INTRODUCTION: In vascular surgery the crossover iliofemoral bypass grafting is a well-known surgical technique. In general surgery the repair of an abdominal defect using a Polypropylene mesh is also a standard procedure. A particular technique is defined by the performance of these 2 separate procedures inside a single operation in which the crossover arterial graft is directed from the retroperitoneal space toward the contra-lateral femoral bifurcation through a Polypropylene mesh which closes the musculoaponeurotic layers of the abdominal wall...

INTRODUCTION: Mangled upper limb injuries are at surge because of industrialization, modernization, and severe motor vehicle accidents. The utility of various scoring systems are meant for decision making in mangled lower limb injuries, and the same have been extrapolated for mangled upper limb injuries to make a decision of salvage or amputation for the lack of separate scoring system. MATERIALS AND METHODS: We applied mangled extremity severity score (MESS) and mangled extremity syndrome index (MESI) scoring systems to 10 cases of mangled upper limb injuries during the period of November 2010 to September 2012 presented at our tertiary trauma care center...

REVIEW
José María González-Santos, María Elena Arnáiz-García
Dilatation of the ascending aorta (AA) is a common finding in patients with aortic valve disease. The clinical practice guidelines recommend replacing the AA whenever the diameter exceeds 45 mm. However, no consensus has been reached regarding the approach when the aorta is only moderately dilated. Although the risk in aorta replacement is generally low, it may be higher when associated with other complex surgical procedures or it is carried out in elderly patients or patients with significant comorbidity. This would justify the use of alternative surgical techniques, which reduce surgical risk and guarantee a durable correction of the aortic pathology...

Some studies consider the different physical properties of the stent graft when compared with the blood vessel on the basis of vascular lesions that may require further intervention. We present a case in which a patient developed an intramural hematoma at the distal landing of previous thoracic endovascular aortic repair (TEVAR) that required the relining with a flared prosthesis. During follow-up, we observed the appearance of more caudal hematoma. We decided to observe this lesion with close radiological controls...

A 54-year-old woman diagnosed with multiple sclerosis (MS) at the age of 19 years was scheduled to undergo temporomandibular joint mobilization. She was currently in a remission phase from her MS but with persistent sequelae, including impaired eyesight and muscle weakness of the limbs. In addition, the blood vessels in her upper limbs were compromised by the formation of internal shunts secondary to vascular prosthesis replacements for plasma exchange therapy in MS. After a previous joint mobilization surgery, her temporomandibular joint developed adhesions with resultant trismus...

PURPOSE: Pulse wave velocity (PWV), which measures vascular stiffness, is a powerful predictor of cardiovascular event. Treatment of aneurysms with endovascular prosthesis has been reported to increase PWV. The purpose of this study was to evaluate whether an endoskeleton stent graft design has less effect on PWV than the exoskeleton stent graft design. METHODS: Between July 2008 and September 2016, 74 patients underwent endovascular treatment of aortic arch aneurysm in our institution...

PCU (polycarbonate polyurethane) is supposed to be an ideal elastomer for manufacturing artificial vessel scaffold with perfect mechanical strength and biocompatibility. Surface grafting by heparin sodium can increase its anticoagulant hemorrhagic, achieving a better application in artificial vessels. Artificial vessels were preliminarily prepared by electrostatic spinning, treated by NH3 plasma and cross-linked with the anticoagulant heparin sodium chemically. Performances of the PCU-Hep (heparin sodium grafted purethane artificial vessels) artificial vessel were calculated through the physical and chemical property tests, evaluation of blood and biocompatibility...

INTRODUCTION: Deep wound infections in the groin region can result in an acute or life threatening condition. Especially when there is no suitable vein available because of many reasons (e.g. previous surgery, small vessel diameter). Synthetic prosthesis sometimes are not 'first-choice-technique' because of contamination or infection. It was ad hoc hypothesized in an acute setting that a segment of an occluded Superficial Femoral Artery (SFA) could be used as a conduit in combination with eversion technique, known from carotid surgery...

Transcatheter aortic valve implantation (TAVI) is recommended for patients who are inoperable or at high risk for surgical aortic valve replacement (SAVR). Corticosteroid therapy is considered to be a risk factor for SAVR, but there is a paucity of information about TAVI in patients taking corticosteroids. The aim of this study is to elucidate the outcome of TAVI in patients on chronic corticosteroid therapy, compared with SAVR. We retrospectively analyzed patients on corticosteroid therapy who underwent TAVI (n = 21) or SAVR (n = 30) for severe aortic stenosis in Sakakibara Heart Institute...

BACKGROUND: The development of a suitable extracellular matrix (ECM) scaffold is the first step in vascular tissue engineering (VTE). Synthetic vascular grafts are available as an alternative to autologous vessels in large-diameter arteries (>8 mm) and medium-diameter arteries (6-8 mm). In small-diameter vessels (<6 mm), synthetic vascular grafts are of limited use due to poor patency rates. Compared with a vascular prosthesis, natural tissue ECM has valuable advantages. Despite considerable progress in recent years, identifying an optimal protocol to create a scaffold for use in small-diameter (<6 mm) fully natural tissue-engineered vascular grafts (TEVG), remains elusive...

Tumor involvement of the inferior vena cava (IVC) by hepatobiliary, pancreatic or duodenal malignancies can compromise adequate resection. However, radical resection with negative histological margins remains the only chance of cure. Various techniques are used for venous reconstruction, using a prosthetic graft interposition in most of the cases. However, in case of associated digestive resections, such as pancreaticoduodenectomy, postoperative complications can be responsible for prosthesis infection and related vascular complications...

BACKGROUND: There are limited clinical records in the literature regarding aortic valve replacement in left ventricular assist device (L-VAD) patients. Previously we had two cases of severe aortic valve regurgitation in patients with L-VAD support treated with Corvalve prosthesis insertion and Amplatzer closure procedure. Both patients died a few days after the procedure from complications not related to the procedure itself. PATIENT HISTORY: The patient was a male with previous coronary artery bypass graft surgery in 2001 that was complicated with postischemic dilated cardiomyopathy with severe heart failure (ejection fraction [EF], 20%)...
