Acute Claudication caused by Angio-Seal Closure Devices: a Report of Four Cases

Femoral artery closure devices are increasingly used after percutaneous arterial interventions to obtain hemo-stasis at the puncture site. Their efficacy and advantages in patient comfort are established. Nevertheless they can cause their own specific complications. In a five month’s period we had to treat four patients with sudden onset invalidating claudication after the use of an Angio-Seal closure device. Malpositioning of the device led to the ischemic complications. We describe and illustrate the pre-and peroperative findings and the treatment. Interventionalists should monitor and register ischemic complications following the use of puncture site closure devices in order to try and minimize these. The occurrence of few serious complications can outweigh the relative small benefits these devices offer.

Transcatheter closure of recurrent postmyocardial infarction ventricular septal defects utilizing the Amplatzer postinfarction VSD device: a case series.

The initial therapy for postmyocardial infarction ventricular septal defects is surgical repair of the defect. Unfortunately, a significant number of patients develop recurrent ventricular septal defects (VSDs) following operative repair. Transcatheter closure offers an alternative to reoperation in these critically ill patients. We present a series of four patients in whom recurrent ventricular septal defects were closed using an Amplatzer VSD device.

目的 :研究非常规方法选择 Amplatzer房间隔缺损封堵器的可行性。方法 :患者 15 8例 ,年龄 1～ 6 5 （2 7士 19）岁。其中常规组 4 1例 ,非常规组 117例。非常规组按照选择封堵器的最终依据不同 ,分为 3组。A组 :33例 ,根据食道超声心动图 （TEE）测量的 ASD最大径直接选择封堵器 ;B组 :4 6例在经胸超声心动图 （TTE）监测指导下球囊充盈测量 ASD伸展径 （BSD） ,根据 BSD选择封堵器 ;C组 :38例 ,根据 TTE测量的 ASD最大径直接选择封堵器。结果 :各组患者 ASD的边缘、大小和选择封堵器的大小之间均无显著性差异 （P>0 .0 5 ）。各组技术成功率均为10 0 %。非常规各组完全闭合率与常规组无显著性差异 （P>0 .0 5 ） ,但手术操作时和 （或 ）透视时间均明显短于常规组 （P<0 .0 1）。结论 :非常规法选择 Amplatzer封堵器对大部分 ASD介入治疗是安全可行的。对于房缺周缘较长、较硬者 ,及边缘为硬缘和极软缘组成而剔除极软缘者 ,TEE或 TTE可直接指导 Amplatzer封堵器型号的选择。对于房缺缘较软者 ,应结合球囊测量房缺伸展径选择封堵器     

Transcatheter closure of atrial septal defects in adults with the Amplatzer septal occluder

OBJECTIVE—To assess the efficacy and complications of device occlusion of atrial septal defects in adults, using the Amplatzer septal occluder (ASO).
DESIGN—A prospective interventional study.
SETTING—Paediatric cardiology departments in two European teaching hospitals.
PATIENTS—The first 20 patients accepted for atrial septal defect device occlusion, on the basis of transoesophageal echocardiography. Sixteen patients had larger defects with right heart dilatation, while the primary indication for closure in four was a history of early paradoxical embolism.
INTERVENTIONS—Transcatheter atrial septal defect occlusions performed under transoesophageal echocardiography and fluoroscopic guidance between December 1996 and June 1998.
OUTCOME MEASURES—Success of deployment of ASO devices, procedure and fluoroscopic times, complications, and symptoms.
RESULTS—The ASO device was successfully implanted in all 20 patients (14 female), median age 44.2 years, with no complications. Of the 16 patients with right heart dilatation, the median Qp:Qs was 2.5:1. Defects measured 11-22 mm (median 18) on transoesophageal echocardiography, with balloon sized diameter (and device size) of 13-28 mm (median 20). For all 20 patients, the procedure time ranged from 38-78 minutes (median 61), and fluoroscopy 8.4-24.7 minutes (median 15.2). There were residual shunts in three patients at the end of the procedure, which were trivial ( 1 mm) as assessed by transoesophageal echocardiography, and persisted for more than six months in only one patient. Follow up ranged from 0.1-1.5 years (median 0.7). There have been no late complications.
CONCLUSIONS—The ASO device can be used successfully to close selected oval fossa defects in adults, with minimal procedural morbidity and excellent early results.

Is there a role for surgery in the management of isolated secundum atrial septal defect in adults?

Isolated atrial septal defect (ASD) is the most common form of congenital heart abnormalities in adults and approximately 80% are located in the region of the fossa ovalis (ostium secundum ASD).1 Indications for closure are in cases where the ratio of pulmonary-to-systemic flow (Qp/Qs) is higher than 1.5, without significant elevation of pulmonary vascular resistance.Surgical closure of ASDs has been performed for over 60 years and techniques have steadily improved, using smaller incisions and minimally invasive techniques. On the other hand, in the last 20 years, various transcatheter ASD closure techniques and devices have been developed, among which, percutaneous treatment with a septal occluder device is the most popular.2,3Despite increasing use of occluder devices and the fact that studies have been published internationally pointing out some of the advantages and disadvantages compared with surgery in adults, no formal comparison of efficacy, morbidity and complications has been published.2-4 We present a retrospective comparison of short-term (three months) results for transcatheter and surgical closure of 163 ostium secundum ASD patients in a university hospital.
