[Ab] Resumo:OBJECTIVES: (1) To develop an observer-free method of analysing image quality related to the observer performance in the detection task and (2) to analyse observer behaviour patterns in the detection of small mass changes in cone-beam CT images. METHODS: 13 observers detected holes in a Teflon phantom in cone-beam CT images. Using the same images, we developed a new method, cluster signal-to-noise analysis, to detect the holes by applying various cut-off values using ImageJ and reconstructing cluster signal-to-noise curves. We then evaluated the correlation between cluster signal-to-noise analysis and the observer performance test. We measured the background noise in each image to evaluate the relationship with false positive rates (FPRs) of the observers. Correlations between mean FPRs and intra- and interobserver variations were also evaluated. Moreover, we calculated true positive rates (TPRs) and accuracies from background noise and evaluated their correlations with TPRs from observers. RESULTS: Cluster signal-to-noise curves were derived in cluster signal-to-noise analysis. They yield the detection of signals (true holes) related to noise (false holes). This method correlated highly with the observer performance test (R = 0.9296). In noisy images, increasing background noise resulted in higher FPRs and larger intra- and interobserver variations. TPRs and accuracies calculated from background noise had high correlation with actual TPRs from observers; R was 0.9244 and 0.9338, respectively. CONCLUSIONS: Cluster signal-to-noise analysis can simulate the detection performance of observers and thus replace the observer performance test in the evaluation of image quality. Erroneous decision-making increased with increasing background noise.

[Ab] Resumo:Tricuspid regurgitation (TR) in infancy poses a surgical challenge. Both two- and three-dimensional echocardiography (3DE) can provide detailed information about the mechanism(s) of valve failure and insights into valve adaptation during follow-up. We report two patients who underwent tricuspid valve repair using Gore-Tex neochordae, repairs which were facilitated by and assessed with 3DE. Both infants had less than mild residual TR and no valve tethering at hospital discharge. Furthermore, follow-up 3DEs have helped to confirm valve competence, lack of tethering, and growth of the valve and valve apparatus.

[Ti] Título:Susceptibility of ePTFE vascular grafts and bioengineered human acellular vessels to infection.

[Ab] Resumo:BACKGROUND: Synthetic expanded polytetrafluorethylene (ePTFE) grafts are routinely used for vascular repair and reconstruction but prone to sustained bacterial infections. Investigational bioengineered human acellular vessels (HAVs) have shown clinical success and may confer lower susceptibility to infection. Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial contamination in a preclinical model of infection. MATERIALS AND METHODS: Sections (1 cm ) of ePTFE (n = 42) or HAV (n = 42) were inserted within bilateral subcutaneous pockets on the dorsum of rats and inoculated with Staphylococcus aureus (10 CFU/0.25 mL) or Escherichia coli (10 CFU/0.25 mL) before wound closure. Two weeks later, the implant sites were scored for abscess formation and explanted materials were halved for quantification of microbial recovery and histological analyses. RESULTS: The ePTFE implants had significantly higher abscess formation scores for both S. aureus and E. coli inoculations compared to that of HAV. In addition, significantly more bacteria were recovered from explanted ePTFE compared to HAV. Gram staining of explanted tissue sections revealed interstitial bacterial contamination within ePTFE, whereas no bacteria were identified in HAV tissue sections. Numerous CD45 leukocytes, predominantly neutrophils, were found surrounding the ePTFE implants but minimal intact neutrophils were observed within the ePTFE matrix. The host cells surrounding and infiltrating the HAV explants were primarily nonleukocytes (CD45 ). CONCLUSIONS: In an established animal model of infection, HAV was significantly less susceptible to bacterial colonization and abscess formation than ePTFE. The preclinical findings presented in this manuscript, combined with previously published clinical observations, suggest that bioengineered HAV may exhibit low rates of infection.

[Ab] Resumo:BACKGROUND: Novel surgical approach to repair degenerative mitral regurgitation such as transapical chordae tendineae replacement and "loop in loop" in loop techniques, need of artificial chordae longer than that used in the older techniques of chordae tendineae replacement. This difference in length has been reported as potential critical point for durability of artificial chordae. In the present paper we have investigated the elastic behavior of different diameter and length politetrafluorene (PTFE) suture threads as substitute of native chordae, to identify their reliability to use as long artificial chordae. METHODS: PTFE suture threads with different diameters were investigated in their mechanical properties at different length from 2 to 14 cm, by a servo hydraulic testing machine, to test the elastic properties of the sample in their use as mitral chordae substitutes. RESULTS: Our study shows that the chordae length is an important parameter that can change the performance of chordae itself. The analysis of elastic/properties of suture threads specimen, reveals that long PTFE chords have an optimal mechanical behavior in which elongation is accompanied by a safe elastic properties that make them well resistance during multiple tractions. CONCLUSIONS: In conclusion the use of PTFE as an artificial chordae may represent a valid choice in case of insertion of artificial chordae with extra anatomic length.

[Ab] Resumo:Diazomethane is among the most versatile and useful reagents for introducing methyl or methylene groups in organic synthesis. However, because of its explosive nature, its generation and purification by distillation are accompanied by a certain safety risk. This protocol describes how to construct a configurationally simple tube-in-flask reactor for the in situ on-demand generation of anhydrous diazomethane using membrane separation technology and thus avoiding distillation methods. The described reactor can be prepared from commercially available parts within ∼1 h. In this system, solutions of Diazald and aqueous potassium hydroxide are continuously pumped into a spiral of membrane tubing, and diazomethane is generated upon mixing of the two streams. Pure diazomethane gas diffuses out of the reaction mixture through the membrane tubing (made of gas-permeable Teflon AF-2400). As the membrane tubing is immersed in a flask filled with the substrate solution, diazomethane is instantly consumed, which minimizes the risk of diazomethane accumulation. For this protocol, the reaction of diazomethane with benzoic acid on a 5-mmol scale has been selected as a model reaction and is described in detail. Methyl benzoate was isolated in an 88-90% yield (597-611 mg) within ∼3 h.

[Ti] Título:Two Cases of Popliteal Cystic Adventitial Disease Treated With Excision and Primary Bypass Graft: A Review of the Literature.

[Ab] Resumo:Cystic adventitial disease (CAD) is a rare vascular pathology which predominantly affects peripheral vessels of young otherwise healthy males. Much debate exists regarding its exact etiology. It is characterized by a collection of mucinous material within the adventitial wall layer of the affected vessel, resulting in arterial stenosis and rapidly progressive calf claudication. Treatment is primarily surgical, although radiological interventions have been reported. Its rarity makes evidence-based surgical or radiological management difficult. With this in mind, we report two cases of popliteal artery CAD treated successfully with primary excision and bypass grafting. We analyzed all literature published on CAD since first reported in 1947 and we propose an algorithm for appropriate management pathways.

[Ti] Título:Comparison of direct site endovascular repair utilizing expandable polytetrafluoroethylene stent grafts versus standard vascular shunts in a porcine (Sus scrofa) model.

[Ab] Resumo:INTRODUCTION: The small diameter of temporary vascular shunts for vascular trauma management may restrict flow and result in ischemia or early thrombosis. We have previously reported a clinical experience with direct, open surgical reconstruction using expandable polytetrafluoroethylene stent grafts to create a "sutureless" anastomosis as an alternative to standard temporary vascular shunts. We sought to characterize patency and flow characteristics of these grafts compared with standard shunts in a survival model of porcine vascular injury. METHODS: Twelve Yorkshire-cross swine received a 2-cm-long near-circumferential defect in the bilateral iliac arteries. A 14 Fr Argyle shunt was inserted into one randomly assigned artery, with a self-expanding expandable polytetrafluoroethylene stent deployed in the other. At 72 hours, conduit patency was evaluated by angiography. Arterial flow measurements were obtained at baseline, immediately after intervention, and after 72 hours via direct measurement with perivascular flow meters. Blood pressure proximal and distal to the conduits and arterial samples for histopathology were obtained during the terminal procedure. RESULTS: Angiography revealed no difference in patency at 72 hours (p = 1.0). While there was no difference in baseline arterial flow between arteries (p = 0.63), the stent grafts demonstrated significantly improved blood flow compared with shunts both immediately after intervention (390 ± 36 mL/min vs. 265 ± 25 mL/min, p = 0.002) and at 72 hours (261 ± 29 mL/min vs. 170 ± 36 mL/min, p = 0.005). The pressure gradient across the shunts was greater than that of the stent grafts (11.5 mm Hg [interquartile range, 3-19 mm Hg] vs. 3 mm Hg [interquartile range, 3-5 mm Hg], p = 0.013). The speed of deployment was similar between the two devices. CONCLUSIONS: Open "sutureless" direct site repair using commercially available stent grafts to treat vascular injury is a technically feasible strategy for damage control management of peripheral vascular injury and offers increased blood flow when compared with temporary shunts. Furthermore, stent grafts may offer improved durability to extend the window until definitive vascular repair. The combination of these traits may improve outcomes after vascular injury. LEVEL OF EVIDENCE: Epidemiologic/Prognostic, level III.

[Ab] Resumo:Posttraumatic tricuspid valve regurgitation (TR) is a rare entity and is almost always associated with blunt chest trauma. It is usually identified by transthoracic echocardiography after the manifestation of clinical symptoms of heart failure. Treatment varies from long-term medical therapy and observation to surgical correction with tricuspid valve replacement or repair. We describe the case of a 26-year-old man who was involved in a major road traffic accident and was referred for surgical repair a year later because of severe posttraumatic TR. The tricuspid valve was successfully reconstructed with a CardioCel patch, Gore-Tex neochordae, and a tricuspid ring. The patient recovered well.

[Ab] Resumo:Introduction:: Although it only corresponds to 2.5% of congenital heart defects, hypoplastic left heart syndrome (HLHS) is responsible for more than 25% of cardiac deaths in the first week of life. Palliative surgery performed after the second week of life is considered an important risk factor in the treatment of HLHS. Objective:: The aim of this study is to describe the initial experience of a medical center in Northeastern Brazil with a modified off-pump hybrid approach for palliation of HLHS. Methods:: From November 2012 through November 2015, the medical records of 8 patients with HLHS undergoing hybrid procedure were retrospectively evaluated in a tertiary private hospital in Northeastern Brazil. The modified off-pump hybrid palliation consisted of stenting of the ductus arteriosus guided by fluoroscopy without contrast and banding of the main pulmonary artery branches. Demographic and clinical variables were recorded for descriptive analysis. Results:: Eight patients were included in this study, of whom 37.5% were female. The median age and weight at the time of the procedure was 2 days (p25% and p75% = 2 and 4.5 days, respectively) and 3150 g (p25% and p75% = 3077.5 g and 3400 g, respectively), respectively. The median length in intensive care unit stay was 6 days (p25% and p75% = 3.5% and 8 days, respectively). There were no in-hospital deaths. Four patients have undergone to the second stage of the surgical treatment of HLHS. Conclusion:: In this series, the initial experience with the modified off-pump hybrid procedure showed to be safe, allowing a low early mortality rate among children presenting HLHS.
