ObjectiveTo explore the early outcomes of the surgical treatment for patent ductus arteriosus (PDA) combined with intracardiac abnormities via right vertical infra-axillary thoracotomy (RVIAT).MethodsA total of 7 children with PDA combined with intracardiac defects underwent surgery through RVIAT at the Second Affiliated Hospital of Nanjing Medical University from 2016 to 2018. There were 4 males and 3 females, with an average age of 5.3±4.5 years and weight of 18.0±11.2 kg.ResultsIn all patients, PDA was ligated before the repair of intracardiac abnormities. No patient died in hospital. All patients were followed up, with a mean follow-up time of 18.0±8.0 months. No other complications such as residual shunts, arrhythmias, hemorrhaging or wound infection occurred after operations or during the follow-up period.ConclusionRVIAT is an emerging technique used for the surgical repair of PDA combined with intracardiac defects. It yields satisfying cosmetic results, without increasing postoperative complications or mortality.

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 explore the method and feasibility of establishing patent ductus arteriosus (PDA) model in Bama miniature pig by using autologous jugular vein, and to provide a large animal model for the development of PDA occluder and the study of pulmonary hypertension associated with congenital heart disease. MethodsFive male Bama miniature pigs weighing about 45 kg were selected to gain the PDA model of the autogenous jugular vein, which was fixed by glutaraldehyde and anastomosed between the ascending aorta and the main pulmonary artery. The patency of PDA was confirmed by echocardiography and angiocardiography immediately and one week after the operation. Two animals were selected to undergo transcatheter closure of PDA via femoral vein 1 week after the operation, and the rest were euthanized to obtain PDA and lung tissue for pathological examination. ResultsThe PDA model was successfully established in all five animals with a success rate of 100.0%. Immediately and 1 week after the operation, echocardiography and angiography showed that PDA blood flow was unobstructed, and hematoxylin-eosin staining showed that PDA endothelialization was good. One week after the operation, two animals were successfully treated with transcatheter femoral vein occlusion. The pathological examination of lung tissue showed thickening of the intima and muscular layer of pulmonary arterioles, thickening of pulmonary interstitium and infiltration of neutrophils. ConclusionIt is safe and feasible to establish a large animal model of PDA by using autogenous jugular vein anastomosis between the ascending aorta and the main pulmonary artery. The model can be used for the development of PDA interventional occlusive devices and the pathophysiological study of congenital heart disease-related pulmonary hypertension.
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.
