ObjectiveTo explore the key points, indications and safety of trans-jugular transcatheter closure of atrial septal defect (ASD) in infants.MethodsThe clinical data of 53 infants with ASD from January 2017 to May 2019 in our hospital were retrospectively reviewed. There were 20 males and 33 females with the age of 1.2 (0.5-2.9) years, and body weight of 9.0 (6.8-10.6) kg. The ASD diameter was 9.8 (8.0-14.0) mm. Thirty-one patients were treated under the guidance of transesophageal ultrasound (TEE), and the other 22 patients under the guidance of transthoracic echocardiography (TTE). We used the steerable curved sheath through the internal jugular vein under the guidance of echocardiography, and the average occluder size was 13.5±4.5 mm.ResultsAll of the 53 patients were successfully occluded, and none of them changed to radiation-guided or transthoracic surgery. Postoperative hospital stay was 3.35±0.70 d. There was no complication such as peripheral vascular injury, occluder malposition or displacement, serious arrhythmia or pericardial effusion. The patients were followed up for 14.3±5.1 months without arrhythmia, residual shunt, occluder malposition or displacement or thrombus.ConclusionEchocardiography-guided trans-jugular closure of ASD for infants with low weight and large ASD shunt or patients with inferior vena cava abnormalities not suitable for femoral vein treatment, not only overcomes the radiation risk of radiation guidance, but also maintains the advantages of minimal invasiveness and safety, providing a new treatment option for such patients.
Long-term chronic internal jugular vein (IJV) insufficiency, originally viewed as a non-pathological finding, may result in cerebral venous outflow disturbance, leading to cerebral venous ischemia and cerebral nervous functional disorders. In this article we discuss probable etiologies, symptoms, diagnosis and treatment of IJV disturbance, so as to provide some insights for clinicians.
ObjectiveTo evaluate the ultrasonic pre locating internal jugular venous cannulation in infants, comparison with the external landmark technique.MethodsSixty two infants scheduled for cardiac surgery were randomized prospectively into two groups. In the anatomic landmarks group( n =30), the patient’s internal jugular vein(IJV) were cannulated by using the traditional method of palpation of carotid pulsation and identification of other anatomic landmarks. In the ultrasonic pre locating group ( n =32), an two dimensional ultrasound scanner image made for locating the puncture site of vessels was used with an operative probe of HP SONOS 4500 system. The number of attempts, success rate, and incidence of complications were compared for two groups.ResultsThe success rate was 100% vs 80% in the ultrasonic pre locating group vs anatomic landmarks group, with a 3.1% vs 26 7% incidence of carotid artery punctures and the number of attempts 1.57±1.04 vs 2.55±1.76. All differences were statistically significant ( P lt;0.05,0.05,0.01). Conclusion Ultrasonographic pre-localization of the IJV is superior to the anatomic landmarks technique in terms of overall success , and decreases incidence of carotid artery puncture.
目的 讨论B型超声定位下颈内静脉穿刺置管的经验。方法 回顾我中心2008年11月至2009年4月期间采用B型超声定位行颈内静脉置管的286例患者的临床资料。结果 一次性穿刺成功率为99.3%（284/286），置管成功率为100%（286/286）； 穿刺时间50 s~12 min，平均106.8 s； 带管时间5～64 d，平均13 d； 未出现血气胸、皮下血肿等并发症。结论 B型超声定位下颈内静脉穿刺操作简单、方便、安全，适用于各级别医院。在颈短肥胖，被动体位情况下，B型超声定位下置管优势大于传统的盲探法及彩色多普勒超声引导下置管法。
