Transcatheter Closure of Patent Ductus Arteriosus in Children with the Occlutech Duct Occluder

Abstract

The aim of this study was to evaluate the feasibility, efficacy and safety of transcatheter closure of patent ductus arteriosus (PDA) with the Occlutech duct occluder (ODO) in children. We reviewed the clinical records of 71 patients who underwent percutaneous closure of PDA with an ODO between September 2014 and August 2016. The Occlutech duct occluder was applied to 71 patients during the study period (September 2014-August 2016), and the results were analyzed in this study. Forty-two of the patients were female and 29 male. The median age was 20.5 months (range, 6-194 months) and median weight was 16 kg (range, 6-68 kg). The PDA was classified as type A in 54 patients (76.1%), type E in 14 (19.7%), type C in 2 (2.8%) and type B in 1 (1.4%) based on the Krichenko classification. A standard ODO device was used for the transcatheter closure procedure in 66 patients and the long-shank ODO device in 5. In the echocardiographic measurement of PDA, the median smallest diameter was 2.7 mm (range, 1.5-7.0 mm), and in the angiographic measurement, the median smallest diameter was 2.5 mm (range, 1.5-6.5 mm). All 71 patients underwent successful PDA closure with the ODO. Angiography following the procedure showed complete closure in 47 patients (66.2%), mild residual shunt in 13 patients (18.3%) and a trivial shunt in 11 patients (15.5%). Color flow Doppler echocardiogpaphy at 24 h post-implantation showed that complete closure was achieved in 65 patients (91.5%), and 6 patients (8.5%) had mild residual shunt. All patients (100%) had complete closure at 30 days of follow-up. The results of this study showed that the Occlutech PDA occluder device is safe and effective in the closure of PDA. As the pulmonary artery side of the device is wider than the aortic side, protrusion toward the aortic side and embolization are prevented, but there is residual shunt in the early period, although this residual shunt disappeared after a few months.

The Outcome of Trans-catheter Closure of Patent Ductus Arteriosus: A Single-Center Experience

“…Occlutech 8/10 PDA occluder was used the most in 14 cases followed by Occlutech 6/8 PDA occluder in 11 patients. The operator preferred the use of Occlutech devices in most cases due to its low cost and easy availability in the regional market as well as high safety profile [ 13 ]. General anesthesia was given in 38 (74.5%) cases due to a higher number of younger children.…”

Deformidad en “forma de claxon” del dispositivo Occlutech-PDA: reporte de un caso

“…The ODO is a self-expanding device that, according to its manufacturers, is designed to close PDA of various morphologies and has been successfully implanted even in hypertensive PDA [2][3][4][7][8][9][10][11] , manufactured with nitinol wire coated with titanium oxide containing PTFE patch inside; marketed for approximately eight years by the Occlutech company whose factories are in Germany and Turkey, in our country the devices of Turkish origin are the ones that arrive 12 .…”

“…To date, the ideal device for the closure of patent ductus arteriosus (PDA) does not exist due to the diversity of its morphologies and sizes 1 . The Occlutech® Duct Occluder (ODO) is a relatively new device on which there are some experiences [2][3][4][5][6][7][8][9][10] . Our objective is to communicate the deformity that an ODO device presented when it was delivered transcatheter.…”

Safety and Efficacy of the Nit-Occlud® Coil for Percutaneous Closure of Various Sizes of PDA

“…The PDA occlusion using NOC did not show significant differences in the success rate according to the types of PDA, and it showed high success rates evenly in each group classified according to the The geometric shapes of PDA devices were developed since angiographic classification of PDA types was established by Krichenko A et al [11]. Some studies reported that the frequency order of PDA types, which consisted of mostly pediatric patients, was as follows: conical > elongated > tubular > window > complex or conical > tubular > elongated > window > complex [12,13]. Most studies reported that the conical type was the most common type of PDA, while the rarest one was the complex type.…”
