Heparin-Bonded Expanded Polytetrafluoroethylene Is a Solution for Infrapopliteal Revascularization in the Absence of an Adequate Autologous Vein Graft.

Background: To analyze the outcomes of heparin-bonded expanded polytetrafluoroethylene (HePTFE) graft as an alternative conduit in infrapopliteal revascularization of chronic limb-threatening ischemia (CLTI) in the absence of an autologous vein conduit.

Methods: A single-center retrospective analysis of patients with CLTI submitted to infrapopliteal bypasses with autologous vein graft (VEIN group) or HePTFE graft (HePTFE group) was implemented. Primary end points were freedom from CLTI at 12 months and recurrence of CLTI at 3 years.

An Epithelioid Hemangioma Camouflaged As Radial Aneurysm.

Epithelioid hemangioma (EH) is an uncommon benign vascular lesion usually present as subcutaneous nodules in the head and neck area. Sometimes, these lesions can occur in the peripheral arteries, and when they do, they can be mistaken for aneurysmal dilatations of that respective vessel. We report a case of a 43-year-old male who underwent surgical recession of a radial aneurysm, which after anatomopathological examination, revealed an EH.

Evaluation of global limb anatomic staging system for patients with chronic limb-threatening ischemia treated with autogenous bypass grafts.

Objective: We evaluated the relationship of the global limb anatomic staging system (GLASS) stage with the clinical outcomes for patients with chronic limb-threatening ischemia (CLTI) who had undergone distal bypass with vein grafting.

Methods: We performed a single-center, retrospective analysis of patients with CLTI who had undergone distal bypass with vein grafting from January 2012 to December 2019. The primary end point was freedom from CLTI, including amputation-free survival, complete wound healing, and no ischemic rest pain.

A real-world analysis of anti-atherosclerotic medical treatment and risk factor control in a cohort of vascular surgery patients.

Introduction: The aim of this study was to assess the pattern of anti-atherosclerosis medicines in patients admitted to a vascular surgery department, the effective control of the target values and its subsequent modification by the vascular surgery team.

Material And Methods: A retrospective single-center cohort study of prospectively collected data was performed between May 2017 and May 2018 in a tertiary center. The STROBE guidelines were followed.

Interface State Reduction by Plasma-Enhanced Atomic Layer Deposition of Homogeneous Ternary Oxides.

Homogeneous ternary oxides of silicon-, niobium-, and molybdenum-aluminate were deposited by plasma-enhanced ALD using sequential metal precursor pulses prior to the oxidation step, to reduce interfacial defects usually observed in nanolaminate growth. The growth kinetics can be understood in terms of competitive adsorption. Trimethyl aluminum (TMA) is strongly chemisorbed to the growth surface and does not permit coadsorption of any of the other precursors; when we lead with a TMA pulse, the resulting film is always AlO.

Clinical aspects and present challenges of the seat belt aorta.

Objective: Seat belt aorta is rare and difficult to manage. The lack of data and follow-up increases the complexity of treating such patients. We aimed to create a decision algorithm by reviewing our current experience and analyzing the presentation and management of our patients.

Clinical outcomes of aortic arch hybrid repair in a real-world single-center experience.

Objective: Aortic arch aneurysmal disease remains a therapeutic challenge. For patients unsuitable for standard open surgery, hybrid repair with debranching of the supra-aortic arteries followed by thoracic endovascular grafting has been shown to be an effective solution. The aim of this study was to report the clinical outcomes of a single-institution experience using hybrid aortic arch repair.

A single-center experience in the eversion femoral endarterectomy.

Objectives: Endarterectomy is the treatment of choice for arterial occlusive disease of the femoral bifurcation. Longitudinal arteriotomy and prosthetic patch angioplasty is the standard technique but, due to the increasing concerns with prosthetic-related infections and multidrug-resistant pathogens our group adopted an alternative approach. We present our experience with eversion femoral endarterectomy.

Hybrid Surgery in Lower Limb Revascularization: A Real-World Experience from a Single Center.

Background: Through the association of endovascular and open procedures, hybrid surgery for lower limb revascularization allows the treatment of multilevel occlusive disease with a lower risk when compared to extensive open interventions. The aim of this study is to evaluate the immediate and midterm clinical outcomes of hybrid techniques for lower limb revascularization in a cohort of patients with multilevel arterial disease.

Methods: Data from elective procedures between 2012 and 2017 were retrospectively collected regarding hybrid lower limb revascularization procedures.

Complete Disruption of The Iliac Vessels During Spinal Surgery With Delayed Presentation.

Introduction: The posterior approach to the lumbar spine is most commonly used to treat lumbar spine pathology. Vascular complications, although rare, have a high mortality rate. This is the report of an arterial lesion complicating a L5 hemilaminectomy and its surgical resolution.

Automatic prebent customized prosthesis for pectus excavatum minimally invasive surgery correction.

Pectus excavatum is the most common deformity of the thorax. A minimally invasive surgical correction is commonly carried out to remodel the anterior chest wall by using an intrathoracic convex prosthesis in the substernal position. The process of prosthesis modeling and bending still remains an area of improvement.

Transthoracic single port with peroral assistance: an animal experiment to assess a less invasive technique for human esophageal atresia repair.

Thoracoscopic repair of esophageal atresia has becoming the gold standard in many centers because it allows a better cosmetic result and avoids the musculoskeletal sequelae of a thoracotomy. Natural orifice translumenal endocopic surgery (NOTES) is a new surgical paradigm, and its human application has already been started in some procedures. In the present study, we explore the feasibility of performing an esophagoesophageal anastomosis using a single transthoracic single port combined with a peroral access in a rabbit model to simulate repair of esophageal atresia by hybrid NOTES in a human newborn.

[Quality of life evaluation of the patients and parents satisfaction after Nuss procedure in the management of Pectus Excavatum].

Pectus Excavatum is the most common congenital deformity of the chest. Although Pectus Excavatum can be associated with heart or lung problems, the main indication for surgical correction of this congenital anomaly is the body image dissatisfaction. The Nuss technique is a minimally invasive procedure that allows the placement of an intrathoracic prosthetic convex bar, previously bended, which mobilize the sternum anteriorly.

CD147 immunohistochemistry discriminates between reactive mesothelial cells and malignant mesothelioma.

Malignant mesothelioma (MM) is a rare form of cancer. Its histopathological diagnosis is very difficult, as it exhibits a number of different appearances that can be misinterpreted as metastatic invasion or atypical hyperplasia. Thus, there is an urgent need to identify adequate markers to distinguish between benign and malignant cells, allowing the implementation of appropriate therapies and, possibly, specific directed therapies.

Assessment of temporal biochemical and gene transcription changes in rat liver cytochrome P450: utility of real-time quantitative RT-PCR.

Purpose: A conventional approach to assess cytochrome P450 (CYP) induction in preclinical animal models involves daily dosing for a least a week followed by Western blot and/or enzyme activity analysis. To evaluate the potential benefit of a third more specific and sensitive assay, real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR), with the objective of reducing the duration of the conventional 1-week study, we simultaneously assessed gene expression by qRT-PCR along with Western blots and enzyme activity assays as a time course in an in vivo model.

Methods: Rats were dosed daily for 8 days with model inducers of CYP1A, CYP2B, CYP3A, or CYP4A.
