Abstract： Objective To optimize surgical treatment for children with patent ductus arteriosus （PDA） and mitral regurgitation （MR） and evaluate its midterm to longterm outcome in terms of MR. Methods Between Jan. 2008 and Jan. 2011， 25 children with PDA and MR underwent surgical treatment in Shanghai Children’s Medical Center. There were 14 male patients and 11 female patients with average age of 26.36±40.75 （1.72-142.83）months and average weight of 8.98±6.85 （3.80-36.00） kg. The average diameter of PDA was 7.84±3.10 （3-15）mm. There were 22 children with duct-type PDA and 3 children with window-type PDA. There were 5 children with severe MR， 18 children with moderate MR， and 2 children with mild MR. Except one child with mitral stenosis who underwent PDA ligation plus mitral valvuloplasty supported with cardiopulmonary bypass， all other 24 children only underwent PDA ligation through left posterolateral thoracotomy without any management for the mitral valve. Results There was no in-hospital death. The average ventilation time in ICU was 6.70±4.39 （3-24） hours. Except one child was reintubated because of asthma， all other children recovered uneventfully without any postoperative complication. All the 25 children were followed up for 329.23±288.39 （29-967） days. During follow-up， 23 children （92.00%） had their MR level ameliorated in different degree. Preoperative severe MR in 5 children changed into moderate MR in 2 children and mild MR in 3 children. Preoperative moderate MR in 16 children changed into none MR in 5 children, trivial MR in 5 children and mild MR in 6 children. Preoperative mild MR in 2 children changed into none MR in 1 child and trivial MR in another child. Two children with preoperative moderate MR had no improvement during follow-up. Conclusion For infants and children with PDA and MR， conservative treatment strategy should be carried out. Simple PDA ligation can provide satisfactory clinical outcome， which may also avoid negative complications including myocardial injury caused by cardiopulmonary bypass.
Abstract： Objective To investigate videoassisted thoracoscopic surgery (VATS) and percutaneous catheter occlusion (PCO) in interruption of patent ductus arteriosus (PDA), in order to achieve minimally invasive surgical injuries and better clinical results. Methods From November 1995 to September 2009, 312 cases of PDA were treated in Fujian provincial hospital, among whom 252 patients were interrupted with VATS(VATS group) and 60 patients with PCO technique(PCO group). For the VATS group, there were 78 males and 174 females aged from 7 d to 31 years old (9.16±8.91 years), while there were 17 males and 43 females aged from 4 to 57 years old (25.55±14.10 years) in the PCO group. We used titanium clip to interrupt PDA under videoassisted thoracoscope for patients in the VATS group, and adopted Amplatzer method for patients in the PCO group. The clinical results, complications and hospital cost in the two groups were compared in this study. Results In the VATS group, all the PDA were successfully interrupted with no residual shunt. In the PCO group, 5% (3/60) of the patients had minor residual shunt after the procedure. No mortality occurred in both groups. Time of the procedure and hospital stay in the PCO group were shorter than that in the VATS group (70.20±31.20 min vs. 112.50±16.30 min, t=6.344,P=0.002; and 4.70±2.20 d vs. 6.50±2.80 d, t=3.241, P=0.022, respectively). However, the hospital cost for each patient in the PCO group was much higher than that in the VATS group (23 222.00±4 333.40 yuan RMB vs. 8 904.50±2 634.60 yuan RMB,t=25.360, P=0.000). Conclusion Compared with PCO, VATS in interrupting PDA can achieved not only excellent clinical results, especially in the newborn and baby cases, but also very satisfying cost which is just a little more than one third of the PCO cost.

ObjectiveTo systematically review the efficacy and safety of ibuprofen for premature infants with patent ductus arteriosus. MethodsDatabases including PubMed, Ovid-EMbase, The Cochrane Library (Issue 11, 2014), CNKI, WanFang Data and VIP were searched to collect randomized controlled trials (RCTs) and quasi-RCTs about ibuprofen for premature infants with patent ductus arteriosus from inception to December 2014. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was conducted by RevMan 5.3 software. ResultsA total of 37 RCTs, involving 2 370 patients were included. The results of meta-analysis showed that, compared with the placebo/blank group, ibuprofen could increase the closure rate of PDA (LBWI:RR=1.93, 95%CI 1.25 to 2.99，P=0.003; VLBW:RR=1.23, 95%CI 1.02 to 1.48, P=0.03; ELBWI:RR=2.86, 95%CI 1.51 to 5.41, P=0.001) and decrease the incidence of sepsis (VLBW:RR=0.21, 95%CI 0.07 to 0.64，P=0.006); Compared with the indometacin groups, ibuprofen could decrease the incidence of the increase of serum creatinine (LBWI:RR=0.11, 95%CI 0.04 to 0.37, P=0.000 2), NEC (LBWI, RR=0.52, 95%CI 0.29 to 0.95, P=0.03) and oliguria (LBWI: RR=0.30, 95%CI 0.16 to 0.56, P=0.000 2; VLBW:RR=1.40, 95%CI 1.03 to 1.92, P=0.03); Compared with the intravenous ibuprofen, Oral ibuprofen could increase the closure rate of PDA (VLBW: RR=1.35, 95%CI 1.12 to 1.62, P=0.002; ELBWI, RR=1.42, 95%CI 1.07 to 1.87, P=0.01). ConclusionCurrent evidence shows that there is not indeterminate between ibuprofen and paracetamol groups. Compared with other general drugs, ibuprofen has an advantage over curing PDA and obviously reduces side effects. Due to the limited quality and quantity of included studies, more high quality studies are needed to verify the above conclusion.
Objective To assess the efficacy and safety of percutaneous closure of patent ductus arteriosus (PDA) solely under echocardiography guidance. Methods We retrospectively analyzed the clinical data of 200 patients who received the percutaneous closure of PDA under echocardiography guidance in Fuwai Hospital from August 2013 to April 2016. According the different approach, they were divided into 2 groups: a femoral artery approach group (n=143) and a femoral vein approach group (n=57). In the femoral artery approach group, there were 42 males and 101 females aged 3.20±5.63 years. In the femoral vein group, there were 10 males and 47 females aged 7.30±11.36 years. All Patients were treated by percutaneous PDA closure solely under echocardiography guidance. The follow-up was performed at one month after the operation by echocardiography, chest radiograph and electrocardiogram. Results All 200 patients were successfully treated with percutaneous closure of PDA. The patients’ gender, in-hospital stay, rates of occluder detachment were similar between the two groups (P>0.05). Compared with the femoral vein approach group, the femoral artery approach group had a younger age (3.20±5.63 yearsvs. 7.30±11.36 years, P<0.001), less body weight (14.25±11.54 kgvs. 24.25±19.14 kg, P<0.001) and shorter diameter of PDA (3.06±0.79 mmvs. 5.93±0.68 mm, P<0.001) and PDA occluders (5.43±1.00 mmvs. 12.14±0.54 mm, P<0.001), but had higher hospitalization expenses (32 108.2±3 100.2 yuanvs.25 120.7±3 534.1 yuan, P<0.001). In the femoral vein approach group, one patient was closed under radiation guidance because guide wires could not pass through PDA. One patient in the femoral artery approach group suffered from occluder detachment at one day after operation and was cured by transthoracic minimally invasive PDA occlusion. There were no complications of occluder detachment, residual shunt, pericardial effusion or left pulmonary stenosis during the follow-up. Conclusion Echocardiography-guided percutaneous PDA closure is safe and effective, while the proper interventional approach should be chosen by the anatomical features of PDA.
ObjectiveTo study effect of different surgical treatments for patent ductus arteriosus in children.MethodA total of 38 patients with patent ductus arteriosus who underwent surgical treatment of cardiothoracic surgery between January 2016 and December 2017 in our hospital were as an observation group (12 patients with severing suture, 26 patients with ligation, 14 males and 24 females, aged 0.08–8.67 years). In the same period, 38 patients with patent ductus arteriosus who underwent interventional closure in the Department of Cardiology were as a control group (17 males and 21 females, aged 0.50–5.42 years). The clinical effectiveness of the two groups was compared.ResultsThe operation time, postoperative hospital stay, and blood transfusion rate in the observation group were higher than those in the control group with statistical differences (P<0.05). There was no statistical difference in intraoperative blood loss and complications between the two groups.ConclusionsIn patients with a single patent ductus arteriosus or a small catheter, interventional closure of the patent ductus arteriosus is less trauma and faster recovery. But in patients with lower weigh, premature, other intracardiac malformations, large catheter, moderate or severe pulmonary hypertension, the surgery is better.
ObjectiveTo compare the efficacy of percutaneous closure guided by transthoracic echocardiography or angiography in the treatment of patent ductus arteriosus (PDA).MethodsLiterature databases such as CNKI, VIP, Wanfang Database, PubMed, Cochrane Library were searched for collecting published literatures on percutaneous closure for PDA guided by transthoracic echocardiography and angiography, retrieval time limit was up to April 2019. Two evaluators independently screened the literature, extracted the data and evaluated the quality according to inclusion and exclusion criteria. The collected data were analyzed by RevMan 5.3 software.ResultsEight studies were included finally, with a total sample size of 681 cases. Meta-analysis showed that there was no statistical difference in the operative success rate between the echocardiography group and the angiography group (RR=0.99, 95%CI 0.97- 1.01, P=0.40). Postoperative complications were less in the echocardiography group than those in the angiography group (RR=0.26, 95%CI 0.11-0.59, P=0.001).The operation time (P<0.000 01), amount of intraoperative radiation (P<0.000 01), exposure time (P<0.000 01), hospitalization days (P<0.000 01) and hospitalization costs (P<0.000 01) in the echocardiography group were less or shorter than those in the angiography group, and the difference was statistically different.ConclusionCompared with angiography-guided, transthoracic echocardiography-guided percutaneous closure for PDA is a safe and effective method with less trauma, lower cost, and can replace angiography as one of the guiding methods for PDA.
ObjectiveTo explore the safety and efficacy of transesophageal echocardiography (TEE)-guided percutaneous intervention for patent ductus arteriosus (PDA) in obese teenagers.MethodsFrom January 2018 to June 2019, 21 obese teenagers with PDA treated with femoral artery occlusion guided by TEE in the Department of Cardiac Surgery, Dalian Children's Hospital of Dalian Medical University were included in this study, including 13 males and 8 females aged 12.8-17.3 (15.1±1.7) years, with an average weight of 51.0-89.0 (73.4±10.1) kg. The operative effect was evaluated. ResultsAll patients successfully received the surgery, and none was changed to radiation-guided or thoracotomy ligation. The average operating time was 23.9±6.8 min, the average postoperative hospitalization time was 3.8±0.6 d. No peripheral vascular injury, intracardiac infection or pericardial effusion occurred. The mean follow-up time was 19.5±4.9 months, and the results of all reexaminations were good.ConclusionFor some PDA children with obesity, emphysema or thoracic malformation, it is difficult to block PDA by transthoracic ultrasound-guided percutaneous intervention, and TEE can avoid the interference of chest wall and lung qi, or other factors. It is an effective supplementary guidance method worthy of promotion.
ObjectiveTo compare the surgical results of ultrasound-guided percutaneous antegrade or retrograde therapy in the treatment of patent ductus arteriosus.MethodsThe clinical data of 166 patients (44 males and 122 females) who underwent transthoracic echocardiography guided closure of patent ductus arteriosus in Xinjiang Cardiovascular and Cerebrovascular Disease Hospital from February 2016 to August 2020 were retrospectively analyzed, and the patients were divided into two groups: an antegrade group (n=60) and a retrograde group (n=106). The operation time, success rate, bed rest time, postoperative complications and surgical safety were compared between the two groups.ResultsThe immediate success rate of the two groups was 100.0%. Compared with the retrograde group, the antegrade group had shorter time of bed rest and hospital stay, but longer operation time. In the retrograde group, there were 2 patients of complications, including occlusive device falling off to pulmonary artery 12 hours after the operation in 1 patient, and false arterial tumor in 1 patient. Both groups were followed up for 3-18 months, and there was no death in the whole group.ConclusionIt is safe and effective to block patent ductus arteriosus under the guidance of transthoracic echocardiography. Although the operation process of anterior occlusion of patent ductus arteriosus is slightly complex and the operation time is long, the indication is wide, and the bed rest time is short. Therefore it can be used as the first choice for patent ductus arteriosus occlusion.
ObjectiveTo explore the safety and effectiveness of different interventional approaches for the treatment of patent ductus arteriosus (PDA) in children.MethodsThe children (≤7 years) who underwent interventional treatment for PDA from 2019 to 2020 in our hospital were retrospectively included. The patients were divided into 3 groups according to the procedures: a conventional arteriovenous approach group, a simple venous approach group, and a retrograde femoral artery approach group. The clinical efficacy of the patients was compared. Results A total of 220 patients were included. There were 78 males and 142 females, with an average age of 3.21±1.73 years, weight of 14.99±5.35 kg, and height of 96.19±15.77 cm. The average diameter of the PDA was 3.35±1.34 mm. A total of 85 patients received a conventional arteriovenous approach, 104 patients received a simple venous approach, and 31 patients received a retrograde femoral artery approach. The diameter of PDA in the retrograde femoral artery group was smaller than that in the other two groups (3.44±1.43 mm vs. 1.99±0.55 mm; 3.69±1.17 mm vs. 1.99±0.55 mm, P<0.001); the contrast medium usage [40 (30, 50) mL vs. 20 (20, 30) mL; 35 (25, 50) mL vs. 20 (20, 30) mL, P≤0.001] and operation time [32 (26, 44) min vs. 25 (23, 30) min; 29 (25, 38) min vs. 25 (23, 30) min, P<0.05] in the simple venous approach group were significantly less or shorter than those in the other two groups; the length of hospital stay of the conventional arteriovenous group was longer than that in the other two groups [3 (3, 5) d vs. 4 (3, 6) d; 4 (3, 5) d vs. 4 (3, 6) d, P<0.05]. There was no significant difference in postoperative complications.ConclusionIt is safe and effective to close PDA through simple venous approach. The retrograde femoral artery approach has the advantage of simplifying the surgical procedure for PDA with small diameters.
