Acute coronary syndrome following arteriovenous fistula creation in a post CABG patient: A steal phenomenon from coronary artery to subclavian artery

A 70‐year‐old man with a history of coronary artery bypass grafting 15 years back and arteriovenous (AV) fistula creation in the left arm 1 month back presented with acute coronary syndrome (ACS). He had not received dialysis before his referral. We felt the most likely etiology for these complaints was increased cardiac oxygen demand from an increased cardiac output related to the newly formed left AV fistula. Coronary angiography was done to detect any significant stenosis in the native or grafted vessels. This revealed that the left subclavian artery was totally occluded in the ostioproximal segment and the coronary arteries did not have occlusions to explain the ACS setting. CT angiography confirmed the angiographic findings of the totally occluded left subclavian artery followed by a well‐developed and patent left internal mammary artery to left anterior descending artery. This led to the consideration of a steal syndrome from the coronary artery by the subclavian artery distal to the occlusion. A successful percutaneous endovascular intervention on the left subclavian artery occlusion was performed. Subsequently, the patient became asymptomatic and experienced a dramatic increase in left ventricular ejection fraction.

目的通过系统药理学和分子对接方法,对薤白治疗冠心病的作用机制进行研究。方法收集薤白的有效化合物;预测这些化合物对冠心病的作用靶点;对这些靶点进行PPI网络图的构建、GO富集分析和KEGG通路注释分析;将这些化合物与靶点进行分子对接。结果薤白共收集到11个有效化合物,作用于30个冠心病相关靶点。PPI网络图显示ALB、ACE、REN、MMP9、MAPK1、NOS3、F2、MMP2、SELE、PPARG为10个联系最多的靶点。GO富集分析显示出66个生物过程、22个分子功能、11个细胞成分,涉及雌激素反应、凝血、冠脉炎症、RAAS系统、抗氧化、稳定粥样斑块6个方面。KEGG通路注释分析显示出13条通路,其中6条通路与冠心病相关,分别是:Estrogen signaling pathway、PPAR signaling pathway、Complement and coagulation cascades、Renin-angiotensin system、HIF-1 signaling pathway and TNF signaling pathway。330组分子对接结果显示233组具有较好的结合活性。结论枳实薤白桂枝汤治疗冠心病具有多成分、多靶点的特点,可能通过抗凝血、稳斑块、抗氧化、抗炎症、降血脂、抑制RASS系统、增加NO保护、促进雌激素分泌8个方面发挥治疗冠心病的作用,且Estrogen signaling pathway是薤白作用冠心病的最主要通路。     

经皮肾镜气压弹道超声碎石在肾结石中的效果

目的 B超引导经皮肾镜气压弹道超声联合碎石治疗肾结石的临床效果。方法选择2017年9月-2018年9月医院收治的肾结石患者82例,按照抽签法的要求将其平均分成对照组(41例:B超引导经皮肾镜气压弹道超声治疗)与试验组(41例:输尿管软镜治疗),分析手术时间、住院时间、出血量、结石清除率、结石的残留率。结果试验组的手术时间、住院时间、出血量。优于对照组,数据比较有差异性,P<0.05。对照组的结石清除率高于试验组、结石的残留率低于试验组,相互比较有差异性,P<0.05。结论在肾结石实际治疗期,使用输尿管软镜钬激光碎石治疗方式。     

冠心病心绞痛患者健康教育和心理护理效果

目的探讨对冠心病心绞痛患者给予健康教育联合心理护理干预后对其生活质量等方面产生的影响。方法选择我院2017年4月-2019年2月收治的100例冠心病心绞痛患者作为实验对象;抽签法分组后探究每组患者护理方式;对照组(50例):选择基础护理方式展开疾病护理;试验组(50例):选择基础护理+健康教育+心理护理方式展开疾病护理;对比各组患者表现出的护理工作满意度以及生活质量评定差异。结果试验组冠心病心绞痛患者护理工作总满意度(98.00%)高于对照组(82.00%)明显(P<0.05);试验组冠心病心绞痛患者睡眠情感、社会生活、精力以及躯体活动评分均高于对照组(P<0.05)。结论冠心病心绞痛患者在接受临床护理工作期间,对于护理工作满意度的提升,各项生活质量指标(睡眠情感、社会生活、精力以及躯体活动)评分结果的提升,均获得明显作用效果,最终对于冠心病心绞痛患者生活质量以及康复状态的显著提升,奠定基础。

The percutaneous learning curve of 3rd generation minimally-invasive Chevron and Akin osteotomy (MICA)

BackgroundMinimally-invasive Chevron and Akin osteotomy (MICA) represents the third-generation percutaneous hallux valgus surgery which is characterized by an extra-articular osteotomy, stable internal fixation and a high potential for correction. Compared to other percutaneous techniques of the foot, MICA is generally regarded as an advanced and demanding surgical procedure with a flat learning curve. The aim of this study is to analyze a single-surgeons experience with his first 50 consecutive MICA procedures.MethodsBetween May 2018 and February 2021, 50 consecutive MICA procedures performed by the author with the "K-wires-First technique" were prospectively analyzed focusing on surgery duration, number of fluoroscopies, correction results and surgery-associated complications. A modification of the original MICA technique as described by its inaugurators Redfern and Vernois allows the use of a standard-sized C-arm and aims to reduce revison rates and conversion to open surgery by placing the guidewires prior to performing the osteotomy.ResultsThe average surgery time for all MICA procedures was 46.8 min (SD 12.1, range 31–90 min). The average amount of fluoro shots required to perform MICA was n = 126.6 (SD 40.8, range 65–231). Comparing the preoperative and 6-week postoperative radiographs, the IMA decreased after MICA by a mean of 10.8° from 16.2° to 5.4° and the HVA by a mean of 22.1° from 30.6° to 8.5°. One case required intraoperative conversion to open hallux correction. There were 4 feet in three patients with secondary screw removal of the Chevron fixation due to prominent proximal screw tips.ConclusionsAlthough the learning curve of 3rd generation MICA is flat and requires specific training and intensive practice, the rate of complications is not elevated compared to other percutaneous hallux valgus techniques. Strict adherence to the principles of 3rd generation MICA with stable fixation and meticulous intraoperative control of each surgical step helps to reduce surgery-associated complications. The learning curve showed a continous improvement in regard to surgery time and use of fluoroscopy. After 40 procedures, the surgery time consistently dropped under 45 min and required less than 100 fluoro-shots. The modified surgical technique may help reduce Chevron screw mal-positioning when using large C-arm fluoroscopy for this procedure.
