动脉导管未闭(PDA)是一种常见的先天性心脏病,经导管封堵治疗已广泛应用于临床。Amplatzer封堵器可用于封堵各种类型PDA,效果佳、创伤小、安全性高。直径≥10 mm的巨大PDA术后易发生溶血、残余分流、封堵器脱落和封堵器脱位等严重并发症[1]。常规PDA封堵器最大直径为20 mm,若需更大直径的封堵器,多选择房间隔缺损封堵器(ASO)或肌部室间隔封堵器。中南大学湘雅二医院2011年 相似文献

BACKGROUND: The dividing line between a patent ductus arteriosus with severe but reversible pulmonary artery hypertension and an Eisenmenger duct remains elusive. Increasing experience with the Amplatzer duct occluder has made non-surgical closure of even large patent ductus arteriosus simple and safe. However, data on the use of this device in severly hypertensive ducti is sparse. METHODS AND RESULTS: There were six patients (2 males, 4 females), wherein transient ductal occlusion was done with an embolectomy balloon catheter. The post-occlusion hemodynamics along with overall clinical and hemodynamic assessment was used to decide the likelihood of benefit of closure and the choice of the device. In four of six patients of patent ductus arteriosus with severe pulmonary artery hypertension (pulmonary vascular resistance index> 8.0 U/m2) the duct was successfully closed using the Amplatzer duct occluder, while in two an Amplatzer ventricular septal defect occluder was used. CONCLUSIONS: Transient balloon occlusion is quite helpful for assessing patients with patent ductus arteriosus with severe pulmonary hypertension, and short-term non-invasive follow-up has shown this strategy to be safe and useful. 相似文献

Objectives: The study aims to find safety of transcatheter closure of large patent ductus arteriosus (PDA) ≥4 mm in patients weighing ≤6 kg.
Background: Large PDA ≥4 mm in patients ≤6 kg challenge the interventionist due to need for large delivery sheath, kink of delivery sheath, and encroachment of aorta or pulmonary artery (PA) by the device. Many institutions refer them for surgery.
Methods: Preterm neonates and ducts with coarctation were excluded. All other patients were taken for catheter closure. Ducts with roomy ampulla were closed with multiple coils aided by bioptome, and others with Amplatzer duct occluders.
Results: Twenty-eight patients aged 2–18 months (median 5.5 months) and weighing 3.8–6 kg (median 4.7 kg) had large PDA (mean diameter 6.3 ± 2 mm) with hyperkinetic pulmonary hypertension. Four patients had bioptome-aided coil closure. Twenty-two other ducts were closed with devices. Two procedures failed due to sheath kink in one patient and device pulling through a duct in the other patient. Four infants needed blood transfusions. The mean procedural time was 42 ± 20 minutes. On a mean follow-up of 25.5 ± 14.8 months, there were no residual flows and no gradients across aorta or pulmonary artery.
Conclusions: Transcatheter closure of large ducts ≥4 mm might be considered safe and effective in infants weighing ≤6 kg also. Decision on coils versus devices depends on ductal morphology. On midterm follow-up with somatic growth, there was no occurrence of aortic or PA gradients. 相似文献

The ductus arteriosus originates from the persistence of the distal portion of the left sixth aortic arch. It connects the descending aorta (immediately distal to the left subclavian artery) to the roof of the main pulmonary artery, near the origin of the left pulmonary artery. Persistence of the duct beyond 48 h after birth is abnormal and results in patent ductus arteriosus (PDA). PDA is rare in adults because it is usually discovered and treated in childhood. Mechanical closure remains the definitive therapy because the patency of ductus arteriosus may lead to multiple complications, depending on the size and flow through the ductus. PDA closure is indicated in patients with symptoms and evidence of left heart enlargement, and in patients with elevated pulmonary pressures when reversal is possible. Transcatheter closure is the preferred technique in adults because it avoids sternotomy, reduces the length of hospital stay and is associated with fewer complications compared with surgery. First demonstrated in 1967, both the technique and the occluder devices used have since evolved. However, designing an ideal PDA occluder has been a challenge due to the variability in size, shape and orientation of PDAs. The present article describes a case involving a 35-year-old woman who presented to the Center for Advanced Heart Failure (Houston, USA) with congestive heart failure due to a large PDA, which was successfully occluded using an Amplatzer (St Jude Medical, USA) muscular ventricular septal defect closure device. The wider waist and dual-retention discs of these ventricular septal defect closure devices may be important factors to consider in the future development of devices for the occlusion of large PDAs. 相似文献

Transcatheter closure of a large patent ductus arteriosus with the clamshell septal umbrella 总被引:2,自引:0,他引:2

In 14 patients undergoing transcatheter closure of a large (greater than 4 mm diameter) patent ductus arteriosus, occlusion was attempted with use of the Bard Clamshell septal umbrella. Patient age ranged from 0.7 to 30.4 years. Isolated patent ductus arteriosus was present in 11 patients; 3 had additional congenital heart lesions. Moderate or severe pulmonary hypertension was present in four patients. The diameter of the patent ductus arteriosus ranged from 4.5 to 14 mm, as determined by contrast injection through an 11F sheath or by balloon sizing; it appeared larger by this method than by the standard angiographic method. All 14 patent ductus arteriosi were successfully closed. Prior embolization of a Rashkind umbrella was the reason for using a Clamshell device in three patients; one additional embolization of a Clamshell device occurred. All errant devices were retrieved at cardiac catheterization, without associated hemodynamic instability. No other complications occurred. Among the 14 patients, 11 had complete ductal closure by Doppler color flow mapping at last follow-up and 3 had trivial residual flow. All four patients having associated complex lesions or pulmonary hypertension, or both, had symptomatic improvement after the procedure, although one child (with Shone's anomaly) died 3 months later. The Clamshell device provides stable and effective closure of a large patent ductus arteriosus, and allows transcatheter closure to be offered to some patients who were previously considered unsuitable for this procedure. 相似文献

The double-disk occluding device suitable for use in infants and children with patent ductus arteriosus, developed by Rashkind and Mullins, has been available to this institution since December 1987 on an investigational basis. Results of 43 nonsurgical ductal closure attempts using this device in children and young adults between December 1987 and October 1988 are presented. Successful implantation was achieved in 42 patients (98%). In 25 patients a residual shunt was seen on angiography immediately after implantation. In 12 patients a residual ductal shunt was detected by Doppler 24 hours after implantation; 6-week follow-up studies showed a small residual shunt in only 3 patients. After a second occluder device was implanted in 2 of these patients, complete closure of the patient ductus arteriosus was achieved. In 1 patient, early in the series, the occluder device embolized to the left pulmonary artery, necessitating surgical removal at the time of ductus division. This event was the only serious complication; there were no deaths. 相似文献

Transcatheter methods for closure of patent ductus arteriosus (PDA) have been known as an effective technique for many years. The devices designed for interventional closure of PDA, coexisting with elevated pulmonary artery pressure are still far from ideal and there is a significant risk of embolisation into the aorta. We present a case of a 14-year-old girl with a large PDA, pulmonary hypertension and congestive heart failure. She underwent successful PDA closure with an Amplatzer atrial septal occluder (ASO), a device originally designed to close an atrial septal defect. 相似文献
