Purpose : Patent ductus arteriosus(PDA) is a common disease in very low birth weight infants(VLBWI). Hemodynamically significant PDA increases the morbidity and mortality of premature infants. Based on experimental model, light inhibits the constriction of immature piglet' s ductal rings. No specific mechanism adequately explains the effect of light on the relaxation of PDA. Several hypotheses, including activation of photosensitive metabolites, alterations in receptors, or...
Nonoperative Treatment of PDA Using the Duct-OccludⓇ
Dong Woon Shin, Kyung Hee Lee, Heon-Seok Han
Clin Exp Pediatr. 1997;40(5):635-640.   Published online May 15, 1997
Purpose : Among the several transcatheter devices of PDA occlusion, Rashikind device was the most extensively experienced, but it had risk of occluder embolism and incomplete occlusion of PDA, approximately 27%. The authors used Duct-OccludⓇ, made of 0.028 inch stainless steel coil. The coil is double cone-shape in released state, and used in streched condition through 4F implantation catheter for...
Effect of Indomethacin Therapy in Prematurity with Patent Ductus Arteriosus:study of Its Effectiveness in Treatment Modality
Yun Kyeong Bae, Seong Woo Roh, Min Jeong Kim, Son Sang Seo
Clin Exp Pediatr. 1996;39(9):1239-1246.   Published online September 15, 1996
Purpose : Conventional indomethacin therapy(0.2mg/kg every 12 hours for three doses) has been used for closure of PDA. The effect of prolonged low dose of indomethacin therapy(0.1mg/kg daily for six days)had been reported in foreign country but, nothing had been reported in our country. So we attempted this study to examine effects of these two methods. Methods : Forty one infants with PDA of...
The Mitral Regurgitation in Patent Ductus Arteriosus (PDA)
Hyang Suk Yoon, Soon Ho Choi
Clin Exp Pediatr. 1994;37(3):317-321.   Published online March 15, 1994
Mitral regurgitation (MR) was analyzed by Doppler echocardiography, preoperatively and postoperatively, in 59 patients with patent ductus arteriosus (PDA). The ratio of left atrial dimension and aortic root dimension (LAD/LOD) and the maximal velocity of the mitral valve (MV max) were compared in pre, postop group. The degree of the regurgitation was given to the MR group. In preop MR...
Color Doppler Echocardiographic Evaluation of Residual Ductal Flow After Surgical Ligation
I Seok Kang, Hyun Kwack, Chung Il Noh, Jung Yun Choi, Yong Soo Yun
Clin Exp Pediatr. 1992;35(5):602-606.   Published online May 15, 1992
We evaluated the incidence of residual ductal flow with color Doppler echocardiography and associated clinical findings in 63 patients who had undergone surgical ligation for isolated PDA, The interval between surgery and color Doppler echocardiographic evaluation ranged from 2 days to6.6 years(mean 7 months). In 40 patients, color Doppler echocardiographic studies were done within 1month after surgery. In 8 of...
Diagnosis of Patent Ductus Arteriosus by Pulsed Doppler Echocardiography; Sensitivity and Specificity.
In Youl Ma, Jin Gon Jun, Jeong Ok Hah
Clin Exp Pediatr. 1987;30(3):275-280.   Published online March 31, 1987
For the determination of the sensitivity and specificity of pulsed Doppler echocardiographic (PDE) diagnosis of patent ductus arteriosus (PDA), we evaluated 108 children with congenital heart disease by suprasternal and parasternal approaches. PDA was diagnosed when continuous turbulent flow(CTF) or PDA jet flow was recorded in main pulmonary artery (MPA) by parasternal approach and when reverse diastolic flow(RDF) was detected in descending aorta and no...
Aortography and Echocardiography by Countercurrent Injection Via Radial Artery in Newborns with PDA.
Jun Hee Sul, Dong Kwan Han, Sung Kyu Lee, Dong Shick Chin
Clin Exp Pediatr. 1986;29(11):1196-1200.   Published online November 30, 1986
Aortography and echocardiography by countercurrent injection into the radial artery performed for the detail diagnosis of PDA in newborns. The results were as follows： 1) Aortography by countercurrent injection via ridial artery affords an easy, safe and simple bedside means for the diagnosis of PDA without retrograde arterial catheterization, which is occasonally complicated by thrombosis of the artery in small infant....
Histological Study of Ductus Arteriosus Affected by Indomethacin in the Fetal Rates.
Young Sook Jang, Chang Yeoul Jeon, Heon Sook Lee, Jung Soo Kim, Moo Sam Lee
Clin Exp Pediatr. 1983;26(8):770-777.   Published online August 31, 1983
This work was perforrred for the observation of morphological changes and beginning portion of obliteration in ductus arteriosus. And also histological findings in ductus arteriosus affected by indomethacin (4ug/kg/day) were studied. The following results were obtained. In the process of obliteration, intimal pillow became irregular with the narrowing of the lumen and loose connective tissue was frequently filled into the...
