Transcatheter occlusion of a residual muscular ventricular septal defect using an Amplatzer duct occluder in a child with congenitally corrected transposition of the great arteries

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 2 2006
Gary E. Stapleton MD
Abstract Transcatheter occlusion has become an acceptable alternative to surgery in patients with congenital muscular and residual post-surgical ventricular septal defects (VSD). We present a case of an 11 year old male with congenitally corrected transposition of the great arteries, dextrocardia, pulmonary atresia, VSD, and advanced second degree atrioventricular block who underwent successful transcatheter occlusion of a residual post-surgical VSD with an Amplatzer duct occluder, in preparation for transvenous pacemaker implantation. © 2006 Wiley-Liss, Inc.

Transcatheter closure of patent ductus arteriosus with Nit-Occlud coils

CATHETERIZATION AND CARDIOVASCULAR INTERVENTIONS, Issue 4 2005
Alpay Celiker MD
Abstract The detachable coils have been successfully used for transcatheter occlusion of small- to moderate-sized patent ductus arteriosus (PDA). We report our experience regarding the use of the Nit-Occlud coils (NOCs) for transcatheter PDA and major aortopulmonary collateral (MAPCA) occlusion. Single NOCs were used to close PDA in 26 patients, and one small and two large MAPCAs in two patients. Mean age and weight of the patients were 7.7 ± 5.4 years and 20.6 ± 11.6 kg. Mean minimum duct diameter was 2.8 ± 0.8 mm; ampulla, 8.7 ± 2.4 mm; and PDA length, 9.3 ± 4.4 mm. Mean pulmonary artery pressure ranged from 9 to 51 mm Hg and pulmonary/systemic flow ratio from 1.1 to 5.8. Ductal shape was conical in 24 patients. Route of approach was venous in 23 and arterial in 3. Successful coil implantation was achieved in 24/26 (92.3%). Mean procedure and fluoroscopy time were 67.2 ± 22.1 and 14.9 ± 6.5 min. The three MAPCAs were also successfully occluded using NOC Medium and Flex. Postimplantation angiograms revealed no leak in 3, a trace or small leak in 17, and a medium leak in 4 patients. Mean follow-up was 7 ± 5 months. Complete occlusion was achieved in 17/24 (71%) at 24 hr, 19/24 (79%) by 1 month, 13/15 (87%) by 3 months, 14/15 (93%) by 6 months, and 10/11 (90%) by 12 months postprocedure. Hemolysis, late embolization, duct recanalization, and flow disturbances were not observed. Transcatheter occlusion of moderate-sized PDAs and MAPCAs using NOCs seems to offer a safe, simple, and controlled method in pediatric patients.

ENDOSCOPIC OCCLUSION OF CYSTIC DUCT USING N -BUTYL CYANOACRYLATE FOR POSTOPERATIVE BILE LEAKAGE

DIGESTIVE ENDOSCOPY, Issue 4 2010
Eric K. Ganguly
Bile leak after cholecystectomy is well described, with the cystic duct remnant the site of the leak in the majority of cases. Endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement has a high success rate in such cases. When ERCP fails, options include surgery, and percutaneous and endoscopic transcatheter occlusion of the site of bile leak. Here, we describe a case of endoscopic transcatheter occlusion of a persistent cystic duct bile leak after cholecystectomy using N -butyl cyanoacrylate glue. A 51-year-old man had persistent pain and bilious drainage following a laparoscopic cholecystectomy. The bile leak persisted after endoscopic placement of a biliary stent for a confirmed cystic duct leak. A repeat ERCP was carried out and the cystic duct was occluded with a combination of angiographic coils and N -butyl cyanoacrylate glue. The patient's pain and bilious drainage resolved. A follow-up cholangiogram confirmed complete resolution of the cystic duct leak and a patent common bile duct. [source]
