BACKGROUND: Coils are the only devices available for transcatheter occlusion of patent ductus arteriosus (PDA) in Japan. Since April 1999, we have introduced a 0.052-inch Gianturco coil (0.052-inch coil) to close PDA >or=2.5 mm. METHODS AND RESULTS: A retrospective survey of the outcome of coil occlusions for PDA >or=2.5 mm before and after the 0.052-inch coil became available found that (1) the frequency of PDA >or=2.5 mm among all candidates for coil occlusion significantly increased after the availability of a 0.052-inch coil (p<0.01); (2) deployment complicated by migration (p<0.01), and prolonged procedure time (p<0.05) were significantly decreased after the introduction of the 0.052-inch coil. In a multivariate logistic regression model for uneventful deployment adjusted for age, pulmonary to systemic flow ratio, and use of a 0.052-inch coil, use of the 0.052-inch coil significantly decreased eventful deployment (p<0.05); and (3) successful deployment of a coil for PDA >or=4 mm significantly increased with the 0.052-inch coil (p<0.01). Complete occlusion was achieved once deployment was successful. CONCLUSION: Introduction of the 0.052-inch coil decreased complicated coil occlusion deployment for PDA >or=2.5 mm, and contributed to a better likelihood of coil occlusion for PDA >or=4 mm. 相似文献

Aneurysm of the peripheral pulmonary arteries is rare. Rupture of pulmonary artery aneurysms manifesting as recurrent hemoptysis with exsanguination is well recognized. We report the case of a young woman who presented with massive hemothorax and shock at the sixth month of pregnancy due to a ruptured lingular artery aneurysm. She was treated with selective coil embolization of the lingular artery to achieve hemostasis. Subsequently, clot evacuation from the pleural space was done. This case is reported for its unsuspected presentation, rarity and to highlight the use of catheter coil embolization to achieve control of bleeding and exclusion of the aneurysm from the pulmonary circulation. 相似文献

For over 30 years, a number of devices have been used for transcatheter vascular occlusion procedures, with varying degrees of success. The most prevalent shortcoming with transcatheter occlusion devices is the lack of device control during implant. In patients with congenital heart defects, transcatheter occlusion is complicated by the wide range of vessel sizes, and various anatomical defects. Gianturco embolization coils are very effective and inexpensive occlusion devices. We report a new procedure for transcatheter vascular occlusion using readily available products (Gianturco coil, bioptome, long sheath) that provides complete control of the coil during implant and excellent results. 相似文献

We present a case of a patient who suffered a rare complication of gastroesophageal varix coil embolization. During a follow up esophagogastroduodenoscopy, 4 years after transjugular intrahepatic portosystemic shunt placement and variceal coil embolization, the coil pack was endoscopically visualized to be eroding into the gastric lumen. 相似文献

We compared in-hospital femoral complications of Angio-Seal, Perclose, and manual compression in consecutive patients who underwent percutaneous coronary interventions in the era of glycoprotein IIb/IIIa platelet inhibition. Femoral closure devices have a similar overall risk profile as manual compression, even in patients treated with glycoprotein IIb/IIIa platelet inhibition, although certain rare complications such as retroperitoneal hemorrhage and severe access-site infection may be more common with the use of these devices. 相似文献

Congenital coronary artery fistula is a rare anomaly that can cause several types of morbidity as well as mortality. Recently, transcatheter coil embolization for congenital coronary artery fistula has been advocated as an effective alternative to surgical repair and is associated with a low morbidity and good clinical outcome. We report a 49-day-old infant who had tachycardia, tachypnea, prolonged and interrupted feeding, cardiomegaly, and continuous murmur, and who underwent successful transcatheter coil embolization for a congenital right coronary artery fistula. At review 1 year after coil occlusion showed that serial plain chest radiographs, myocardial enzyme analysis, electrocardiography, and wall motion on echocardiography were normal. 相似文献

Different coils have been used to close the patient ductus arteriosus (PDA). In small- and moderate-sized PDA, coils are an adequate alternative to surgery and/or to other devices. The aim of the study is to review and discuss the advantages and disadvantages of using coils (excluding PFM coils PFM Medical, Germany) to close PDA. Cambier was the first to successfully close a PDA using a Gianturco coil. To date, thousands of patients worldwide have undergone transcatheter closure of PDA using this or other types of coils. The use of coils is analyzed with regard to costs in comparison with other therapeutic modalities; techniques--anterograde, retrograde approach, selection of coil size--in relation to the size of the PDA and the available sizes of coils; efficacy of the rate of complete occlusion and the need for reocclusion; and safety in relation to embolization rate, other complications including hemolysis, left pulmonary artery LPA stenosis and coarctation. It is concluded that coils are a cheap alternative for the occlusion of PDA in the small-to-moderate PDA. The technique can be learned quite quickly, it has a high rate of complete occlusion, and has an acceptable rate of safety. The disadvantages include a moderate rate of coil embolization and of hemolysis in patients with residual shunt after coil occlusion in large PDAs. When more than one coil is used, the potential for developing LPA stenosis is high. 相似文献

SVG aneurysms are relatively rare clinical entities most often encountered discovered as an incidental finding in patients with prior CABG surgery. There is a substantial risk of complications including rupture and death, thus surgical or percutaneous management may be considered in particular in symptomatic patients. Here, three cases are presented highlighting various percutaneous management options and considerations, including covered stent placement, coil occlusion, and a combined approach with the use of a peripheral covered stent. Intervention within this patient population lacks large population long-term outcomes and as such should be performed carefully by experienced operators, often the guidance of a Heart Team based approach. 相似文献

Distal coronary perforation is a rare, yet potentially lethal complication of percutaneous coronary intervention. Early recognition and treatment remains critical in preventing potentially life‐threatening adverse outcomes, such as cardiac tamponade. The most commonly used strategies for treating distal perforation are fat and coil embolization. We present two cases of guidewire‐induced distal coronary perforation and discuss the advantages and disadvantages of coil vs. fat embolization. © 2016 Wiley Periodicals, Inc. 相似文献

INTRODUCTION: Atrial defibrillation can be achieved with standard implantable cardioverter defibrillator leads, which has led to the development of combined atrial and ventricular devices. For ventricular defibrillation, use of an active pectoral electrode (active can) in the shocking pathway markedly reduces defibrillation thresholds (DFTs). However, the effect of an active pectoral can on atrial defibrillation is unknown. METHODS AND RESULTS: This study was a prospective, randomized, paired comparison of two shock configurations on atrial DFTs in 33 patients. The lead system evaluated was a dual-coil transvenous defibrillation lead with a left pectoral pulse generator emulator. Shocks were delivered either between the right ventricular coil and proximal atrial coil (lead) or between the right ventricular coil and an active can in common with the atrial coil (active can). Delivered energy at DFT was 4.2 +/- 4.1 J in the lead configuration and 5.0 +/- 3.7 J in the active can configuration (P = NS). Peak current was 32% higher with an active can (P < 0.01), whereas shock impedance was 18% lower (P < 0.001). Moreover, a low threshold (< or = 3 J) was observed in 61% of subjects in the lead configuration but in only 36% in the active can configuration (P < 0.05). There were no clinical predictors of the atrial DFT. CONCLUSION: These results indicate that low atrial DFTs can be achieved using a transvenous ventricular defibrillation lead. Because no benefit was observed with the use of an active pectoral electrode for atrial defibrillation, programmable shock vectors may be useful for dual-chamber implantable cardioverter defibrillators. 相似文献

Transcatheter coil occlusion of the patent ductus arteriosus (PDA) has become the interventional treatment option of choice. Immediate occlusion of any residual shunting results in excellent closure rates, but frequently requires multiple coil deployment. Aims: To assess the efficacy and limitations of single Cook detachable coil PDA closure compared to a preceding series of Rashkind umbrella procedures. Methods and results: Between 1990 and 1999, transcatheter occlusion of a small (<2 mm; n=45) or moderate-sized (2-4 mm; n=47) PDA was successfully attempted in 90/92 consecutive patients (mean age 6+/-4.8 years) with a coil (39/41) or Rashkind device (51/51). Immediate angiographic closure rates for both devices were low, although better for small (54-68%) than moderate ducts (7-22%, P<0.01). A 2-year echocardiographic closure rate of small ducts increased to 92% for the coil group versus 95% for the Rashkind group. By that time, moderate-sized ducts were only occluded in 64% with the coil and 54% with the Rashkind device. A visible residual shunt at post-implant angiography in moderate ducts was associated with a high incidence (59%) of long-term echocardiographic shunt patency and a need for repeat interventions for audible residual shunts (32%). Conclusions: Single coil transcatheter occlusion is the treatment of choice for the small duct as most residual shunts will resolve spontaneously. However, long-term shunt persistence after single coil deployment in moderate sized ducts is as frequent as with the Rashkind device. A primary multiple coil approach is advocated if the postcoil aortogram shows residual ductal shunting and if there is persistence of a ductal murmur on auscultation. 相似文献

OBJECTIVE: To evaluate relative lung perfusion following complete occlusion of persistent arterial duct with detachable Cook coils. METHODS: Ductal occlusion using detachable coils was performed in 35 patients (median age 3.9 years, range 0.5 to 16; 32 native ducts, three patients with previous devices). If the duct could be crossed with a 0.035 inch guidewire and a 4 F catheter after coil implantation, a further coil was implanted. Between one and seven coils were used (median two). RESULTS: Complete ductal occlusion was confirmed by echocardiography 24 hours after the procedure in all patients. Lung perfusion scans were performed three months after the procedure in 33 of 35 patients (two older patients with a single coil each did not attend). Decreased perfusion to the left lung (defined as < 40% of total lung flow) was observed in only one patient, who had previously had a 17 mm Rashkind umbrella implanted. There was no correlation between left lung perfusion and peak left pulmonary artery Doppler velocities (r = 0.27 and p = 0.125 for the entire group; r = 0.29 and p = 0.124 after excluding patients with previous devices). CONCLUSIONS: Coil occlusion is effective in achieving complete closure of the duct. An aggressive approach using multiple coils did not compromise perfusion to the left lung. 相似文献

Objectives . We report the use of non‐ferromagnetic embolization coils for transcatheter PDA closure. Background . Transcatheter patent ductus arteriosus (PDA) closure has been performed for 40 years. A number of devices have been used with varying degrees of success. Gianturco embolization coils have been used frequently since 1992 with excellent results. These coils are a stainless steel alloy, and create an artifact when subsequent MRI imaging is performed. Methods . Eight patients underwent right and left heart catheterization and transcatheter PDA closure. Angiography displayed a PDA with left to right shunting. The minimum PDA diameter was measured. An Inconel MReye coil was implanted using standard retrograde technique. A postimplant angiogram was performed. Evaluations were performed the following morning and after 2 months. Results . The median age was 5.5 years, median weight was 24 kg. The PDA minimum diameter was 1.7 mm (range 1.4–2.4 mm), with a median Qp:Qs=1.33:1. In all patients, the PDA was completely immediately closed using one Inconel coil. Two patients also had a small aorto‐pulmonary collateral vessel that was occluded using a separate Inconel coil. All patients had follow‐up evaluation the following day; the PDA remained completely occluded and there was no obstruction of the pulmonary artery branches or descending aorta. Seven patients had subsequent follow‐up and echocardiograms; the PDA remained completely occluded. There were no complications. Conclusion . The Inconel MReye coil is safe and effective for coil occlusion of small PDA and aorto‐pulmonary vessels. Additional studies are needed to define the maximum vessel diameter for Inconel coil occlusion. © 2008 Wiley‐Liss, Inc. 相似文献

BACKGROUND: Different types of coils have been designed for transcatheter closure of persistent arterial ducts. We compared the efficacy and safety of three types of coils: Gianturco coils (Cook), Cook detachable coils (Cook), and Duct Occlud devices (pfm). METHODS: Sixty-three patients underwent coil occlusion of arterial ducts between April 1995 and July 2000. The mean age and weight were 4.8+/-3.4 years and 16.5+/-7.6 kg, respectively. The results and complications of ductal occlusion among the three types of coils were compared. Kaplan-Meier analysis was used to assess reduction in the prevalence of residual shunt with time, and multiple regression analysis was performed to identify predictors of complete occlusion. RESULTS: Coil occlusion of persistent arterial ducts that measured 2. 2 +/- 0.8 mm was feasible in 90% (57/63) of patients. Gianturco coils were used in 29, Duct Occlud devices in 16, and Cook detachable coils in 12 patients. The prevalence of residual shunt at 24 hours, 6 months, 12 months, and 24 months was 42%, 20%, 18%, and 14%, respectively. The reduction in prevalence of residual shunt with time tended to be greater when Gianturco coils were used (P =. 067). Logistic regression identified the use of Gianturco coils to be a significant predictor of complete ductal occlusion on follow-up (P =.04). Pull-through of coils occurred in 4.8% (3/63) and coil embolization in 6.3% (4/63). There was no association between the type of coil and the risk of embolization (P = 1.00). CONCLUSIONS: Transcatheter occlusion of small persistent arterial ducts with coils is safe and effective. There is no advantage of detachable coils (Cook detachable coils and Duct Occlud devices) over nondetachable Gianturco coils in reducing the risk of embolization. Our findings are in favor of the inexpensive, but more effective, Gianturco coils for occluding small arterial ducts of 3 mm or less. 相似文献

Magnetic resonance imaging (MRI) findings in three patients with primary anorectal malignant melanoma are described. Two patients had melanotic and one had amelanotic anorectal melanoma. The findings of MRI with a pelvic coil and an endorectal coil were consistent with pathologic findings. MRI with a pelvic coil demonstrated the melanotic component as high signal intensity on T1-weighted imaging. MRI with a pelvic coil and an endorectal coil was useful for staging anorectal melanoma. This article describes the initial report of the use of an endorectal coil for malignant melanoma of the anorectum. 相似文献

Visceral artery pseudoaneurysm is a rare and potentially life-threatening vascular entity with a high mortality rate, conventionally managed with digital subtraction angiography with coil embolization or surgery. However, in cases where angiographic coil embolization is not possible due to technical reasons, computerized tomography (CT)/ultrasonography-guided thrombin injection remains a viable option as described in the literature. In this case series, we intend to highlight the role of endoscopic ultrasound-guided thrombin injection in the management of abdominal visceral artery pseudoaneurysm, which is either inaccessible by endovascular route or have high surgical risk of complication. 相似文献

Although rare, a congenital direct fistula connection between the proximal right pulmonary artery and the left atrium can present as cyanosis in the newborn. We report the first case in which catheter-based coil closure of such a fistula in a neonate resulted in rapid clinical improvement, obviating the need for surgical repair. 相似文献

Objectives: The present study evaluates two transcatheter closure strategies utilized at a single center and makes recommendations for device selection when occluding the patent ductus arteriosus. Background: A variety of devices are available for transcatheter closure of the patent ductus arteriosus (PDA) but no guidelines exist to guide operator device choice. Methods: A total of 132 patients underwent attempted transcatheter PDA closure utilizing one of two consecutive closure strategies between January 2000 and June 2005. Strategy A (n = 64; January 2000–May 2003) utilized Gianturco coils only. Strategy B (n = 68; June 2003–June 2005) utilized a single Gianturco coil for the PDA with a minimal diameter ≤1 mm (n = 28) or an Amplatzer Duct Occluder (ADO) if the PDA diameter exceeded 1 mm (n = 40). Success was defined as complete occlusion on a follow up echocardiogram. Results: 58 of 64 (90.6%) patients treated utilizing strategy A had successful coil implantation. 68 of 68 (100%) patients treated utilizing strategy B had successful coil/device implantation. At follow up echocardiography, 32 of 44 (72.7%) strategy A patients had complete ductal closure, as compared with 57 of 58 (98.3%) strategy B patients (P < 0.0001). Stepwise logistic regression analysis identified closure strategy as the most powerful predictor of procedural success (OR = 85.9; CI 5.6–9.99). Conclusions: A transcatheter PDA closure strategy consisting of a single Gianturco coil for PDA ≤ 1 mm or an ADO for larger sized PDA (strategy B) achieves superior outcomes compared to the use of coils alone. © 2008 Wiley‐Liss, Inc. 相似文献

The risk of left ventricular perforation is a rare but well-recognized complication of percutaneous double balloon mitral valvuloplasty that usually requires surgical bailout. We describe a case of left ventricular perforation with cardiac tamponade, caused by the propulsion of the balloons during balloon mitral valvotomy on an 86-year-old female with previous thoracotomies that was resolved using percutaneous coil embolization of the perforation. This approach to these types of complications, although unlikely to be of extensive use, will serve to expand the horizon of options in the field of interventions. Cathet. Cardiovasc.
