Background
Arterial vascular anomalies in patients undergoing kidney transplantation (KT) are correlated with a higher incidence of early surgical complications, potentially causing graft loss. Arterial reconstruction allows patients to overcome these surgical challenges, thus minimizing the risk of poor outcomes. The aim of the present study is to retrospectively investigate the safety and effectiveness of the multiple arterial reconstruction technique with a Teflon patch in case of an unavailable aortic patch: to do so, surgical complications, graft function, and patient survival were evaluated.Methods
During the period January 2009 to August 2016, 202 adult deceased-donor KTs were performed at our center. Group A (n = 27; reconstruction of multiple arteries) and Group B (n = 175; control group) were compared.Results
No differences were observed between the 2 groups in terms of early postoperative course, with no vascular complication observed in Group A. No vascular patch infections were reported, nor longer cold ischemia time rates. Similarly, long-term survival rates were similar between the 2 groups.Conclusions
The Teflon-patch arterial reconstruction technique appears to be safe and effective, with an acceptable balance of benefits and potential risks of using a prosthetic material. Studies based on larger series are needed to further validate this approach. 相似文献3.

In HIV/AIDS research, few studies to date have evaluated ways to improve parental HIV disclosure practices using feedback from HIV-negative children who have recently experienced this event. We conducted semi-structured in-depth interviews with 20 children (aged 6–15) who were partially to fully aware of their parents’ HIV status in rural Guangxi, China. Of the 20 children, eight children who were of older age (11.38 years in average) endorsed parental HIV disclosure, five discouraged it and seven expressed uncertainty. Children’s different experiences and attitudes towards disclosure were seen to be associated with their family dynamics (especially the parent–child relationship), social support and care, experiences of stigma and discrimination, psychosocial suffering, comprehension of the disease and the children’s age. Our study contributes to building a child-centered comprehensive understanding for Chinese parental HIV disclosure. It is imperative that counselors and community advocates assess and help parents achieve optimal readiness preceding disclosure of their illness to their HIV-negative children. 相似文献

目的:总结主动脉窦瘤破裂的手术适应症、手术方法和预后。方法:回顾性分析2011年1月至2017年12月因主动脉窦瘤破裂于我院行外科手术治疗的130名患者资料。其中男性58例(44.62%),女性72例(55.38%),年龄32~75(52.72±13.87)岁。合并室间隔缺损55例(42.31%),合并主动脉瓣关闭不全39例(30%),合并房间隔缺损12例(9.23%),合并三尖瓣关闭不全8例(6.15%),合并二尖瓣关闭不全6例(4.62%),合并主动脉夹层1例(0.77%),合并其他心脏疾病9例(6.92%);破裂开口起源于右冠窦119例,起源于无冠窦11例。所有患者均在中低温体外循环下行手术治疗。结果:所有患者中,2例患者围术期死亡,余128例患者随访5个月至5年,术后心功能恢复至I-II级。结论:一旦发现主动脉窦瘤破裂,应积极予以治疗。 相似文献
