Efficacy of Oral Anticoagulation in Stroke Prevention among Sinus-Rhythm Patients Who Lack Left Atrial Mechanical Contraction after Cryoablation

The customary recommendation is that oral anticoagulation be withdrawn a few months after cryoablation for atrial fibrillation, independently of left atrial mechanical contraction in patients in sinus rhythm. Recently, a 5-fold increase in stroke has been described in sinus-rhythm patients who lack atrial mechanical contraction. One aim of this study was to evaluate the efficacy of oral anticoagulation in preventing postoperative stroke in such patients.This prospective study divided 154 sinus-rhythm patients into 2 groups, depending on the presence (108 patients) or absence (46 patients) of left atrial mechanical contraction at 6 months after surgery, and monitored them annually for 5 years. Those without left atrial contraction were maintained on acenocumarol. The primary endpoint was the occurrence of ischemic stroke.The median follow-up period was 29 ± 16 months; 4 patients (2.5%), all belonging to the group with preserved atrial contraction, had ischemic stroke; the group of patients without left atrial contraction had no episodes of stroke during follow-up. Logistic binary regression analyses showed no evidence of factors independently predictive of stroke.Among anticoagulated patients in sinus rhythm without left atrial contraction, we found the incidence of stroke to be zero. In a small, nonrandomized group such as this, we cannot discount the element of chance, yet we suggest that maintaining anticoagulation might lower the incidence of stroke in this population.     

应用负压封闭引流治疗高位小肠瘘

目的观察和评价采用负压封闭引流(vacuum sealing drainage,VSD)治疗高位小肠外瘘的临床效果。方法笔者科室2014年3月~2015年12月收治12例高位小肠外瘘患者,其中男性7例,女性5例,年龄32~65岁,平均52岁。对瘘口及瘘道采用VSD进行引流,同时辅以营养、支持、抗感染等手段进行治疗。结果全组患者瘘口全部关闭愈合,避免了手术,且愈合时间较短,平均愈合时间45.3d。结论采用VSD应用于高位小肠外瘘引流效果较常规方法优势明显,既能有效控制感染,又能明显缩短愈合时间,值得推广。     

Fetal and Neonatal Imaging and Strategy of Primary Neonatal Heart Transplantation in Hypoplastic Left Heart with Ebstein's Anomaly

We present the anatomic constellation of mitral stenosis/aortic atresia variant of hypoplastic left heart syndrome, Ebstein's anomaly, and partial anomalous pulmonary venous return, an exceeding rare congenital heart defect. Prenatal echocardiography led to concern about the capacity of the right ventricle to increase cardiac output with lung expansion and pulmonary arterial runoff at birth, prompting the precaution of extracorporeal membrane oxygenator standby at delivery. Stage I palliation was not attempted, and control of pulmonary arterial blood flow was achieved with pulmonary artery banding, allowing sufficient ongoing hemodynamic stability. Orthotopic cardiac transplantation, repair of hypoplastic aortic arch, and primary sutureless repair of left pulmonary veins was performed, using dual‐site arterial cannulation and continuous mild hypothermic cardiopulmonary bypass. We discuss how this unique echocardiographic anatomy influenced the surgical decision and point out how it guided therapy toward a strategy of primary transplantation rather than standard staged surgical palliation.     

微创化治疗急性化脓性胆管炎17例临床分析

目的总结提高ERCP、PTCD治疗对急性化脓性胆管炎的紧急救治水平;方法回顾性分析我科收治的17例微创治疗急性化脓性胆管炎患者临床资料,所有患者均接受抗感染、补液等一般治疗;结果单纯行内镜下逆行胰胆管造影(ERCP)治疗的患者为14例,其中十二指肠乳头切开取石和(或)鼻胆管引流(ENBD)9例,行胆管支架置入术者5例;在行胆管支架引流的患者中,1例为肝门部肿瘤,外院行胆管支架植入术后7月余,此次引流后,其症状明显缓解,体温逐步恢复正常;经皮肝穿刺胆管引流(PTCD)的患者3例,2例治愈,1例缓解;所有患者均未出现严重并发症。结论 ERCP等微创治疗方式对急性化脓性胆管炎具创口小,较少影响患者生活质量,效果佳的优势。
