Subclavian artery laceration: A serious complication of needle decompression

A 31‐year‐old woman presented with spontaneous tension pneumothorax. This was initially treated with needle decompression, which led to massive haemothorax. Treatment and methods to reduce the likelihood of this complication are discussed.     

An alternative angiographic view to unmask the hidden patent ductus arteriosus during device closure

Transcatheter closure of patent ductus arteriosus (PDA) with various devices has been evaluated worldwide and in selected cases can be performed successfully, thus avoiding the morbidity associated with surgical closure. Traditionally, left lateral projection is adopted for angiographic visualization of the PDA. However, rarely due to anatomical variations of the ductus, it may be difficult to properly visualize and deploy device in above‐said traditional view. In such cases, right anterior oblique projection may be used for proper visualization. © 2012 Wiley Periodicals, Inc.     

Ten‐year Angiographic Result of a Large Right Coronary Artery Fistula Treated Percutaneously: Many Questions Remain Unanswered

We describe an adult patient with right coronary artery to right atrium fistula, which was treated percutaneously 10 years earlier. His coronary angiogram done presently demonstrated no residual fistula, but there was persistence of aneurysmally dilated proximal right coronary artery segment that gave rise to many unanswered questions regarding management of coronary artery fistulas. We discuss the short‐ and long‐term therapeutic dilemmas in the management of coronary artery fistula.     

可重复性小鼠局灶性脑缺血/再灌注模型的探讨

目的介绍一种标准的小鼠局灶性脑缺血/再灌注模型的制作方法,并观察不同脑缺血/再灌注时间脑梗死体积和脑水肿的变化。方法用腔内线栓法制作脑缺血/再灌注动物模型,用TTC染色法进行脑大体观察,用甲酚紫染色法观察脑切片梗死灶,用脑血流激光多普勒监测脑血流的变化,用ImageJ软件计算脑梗死体积和脑水肿。结果当线栓封闭大脑中动脉时,脑血流就会急剧下降至最低水平,拔出线栓后脑血流迅速上升至缺血前水平。脑缺血后,脑片上呈现明显的梗死灶,脑梗死体积和脑水肿的大小较恒定。脑缺血90min再灌注24h组梗死体积、脑水肿体积、脑水肿百分数及神经功能缺损程度均显著大于脑缺血30min再灌注24h组(P<0.001)。脑缺血30min/再灌注72h脑水肿非常明显(72.6±4.3)mm3,再灌注7d时脑水肿开始减退,仅为(50.9±4.1)mm3,再灌注30d时脑容积出现萎缩,脑水肿呈负值(-20.1±1.8)mm3。结论该小鼠局灶性脑缺血/再灌注模型具有重复性好、容易操作的优点。脑缺血30min就可造成不可逆性脑损害,脑水肿在再灌注72h即达到高峰。
