Axillary skin crease incision versus conventional posterolateral incision in open repair of patent ductus arteriosus for extremely low birth weight infants: a retrospective study. BMC Surg 2023; 23:168.

Abstract
BACKGROUND Thoracotomy with posterolateral incision (PLI) is commonly used for surgical repair of patent ductus arteriosus (PDA) in extremely low birth weight (ELBW) infants. Some reports have described thoracotomy for PDA using an axillary skin crease incision (ASCI) in consideration of cosmetic problems such as surgical wounds and thoracic deformities, but the details remain unclear. METHODS In this study, we performed clipping ligation by thoracotomy with ASCI for ELBW infants with PDA from 2011 to 2015 for the purpose of improving cosmetic results, and retrospectively compared the results with those for conventional PLI cases performed from 2016 to 2020. RESULTS ASCI was found to be associated with serious surgical complications and showed a significant difference in outcome parameters only for surgery time, suggesting a safety problem for ASCI. Considering these results, PLI allows clipping of the nearby PDA from the thoracotomy wound while looking straight ahead, whereas the PDA in ASCI is positioned deep and oblique to the thoracotomy wound, so the clipping angle is limited and accurate completion of the procedure is difficult. CONCLUSIONS Regarding PDA repair in ELBW infants, ASCI shows a high risk of serious surgical complications. Conventional PLI remains preferable for safe and accurate results.

Abstract
BACKGROUND Patent ductus arteriosus (PDA), which disrupts the hemodynamics early after birth, causes intraventricular hemorrhage and neonatal necrotizing. Unlike medical treatment for hemodynamically significant PDA, there are institutional disparities in the criteria for surgical treatment METHODS: We aimed to clarify the postoperative indications of surgery for hemodynamically significant PDA and the postoperative complications associated with surgery. RESULTS Thirty-six extremely-low-birthweight infants (median gestational age 25.2 weeks, median birthweight 699 g) required video-assisted thoracoscopic surgery for PDA (VATS-PDA). The treatment indication of VATS-PDA was resistance to medical treatment in 17 cases, relapsed PDA in 15 cases, and no additional administration of indomethacin because of severe side effects in four cases. Complications with VATS-PDA occurred in eight of 36 cases. There were three cases of pneumothorax, two of thoracotomy transition, two of pulmonary hemorrhage, and four of post-ligation cardiac syndrome (PLCS). VATS-PDA-related death occurred in two cases due to PLCS. The frequency of four or more administrations of indomethacin, with or without postoperative complications, was 88% vs. 39%, respectively (P = 0.04). CONCLUSIONS All postoperative deaths were caused by PLCS, which had the highest risk of poor prognosis. VATS-PDA should be considered for unclosed PDA after one course of indomethacin administration.

Abstract
OBJECTIVE The aim of this study is to report on the short-term and mid-term outcomes of preterm infants who underwent patent ductus arteriosus ligation through anterior mini-thoracotomy. METHODS Data for 103 preterm infants who underwent patent ductus arteriosus clipping through an anterior mini-thoracotomy at the 2nd intercostal space between 2009 and 2019 were retrospectively reviewed. The patients were divided into two groups according to their weight at the time of surgery. The complications, morbidity, and mortality rates of each group were compared at postoperative day 30 and at the end of 1 year after surgery. RESULTS During the operation, the median weight of the patients was 900 g (IQR 800-1125 g), the median age was 21 days (IQR 14.5-29 days). The lowest body weight was 460 g. In three patients (3%), there was intraoperative bleeding from the patent ductus arteriosus that required transition to median sternotomy. In one patient (1%) a residual patent ductus arteriosus that required reoperation was observed. Twelve patients (12%) died in the first 30 days postoperatively. Six patients (6%) died between the postoperative day 30 and 1 year. There was no statistically significant difference in the rates of mortality, morbidity, and complication between the groups. CONCLUSIONS Based on our observations of over a hundred preterm infants with patent ductus arteriosus over a decade, ligation through anterior mini-thoracotomy is the main surgical procedure of choice for this patient group in our clinic. Our findings demonstrate the safety of this approach and we believe that it can be successfully replicated in other institutions.

Abstract
The optimal management approach of the patent ductus arteriosus (PDA) in premature infants remains uncertain owing the lack of evidence for long-term benefits and the limited analyses of the complications of medical and surgical interventions to date. In recent years, devices suitable to plug the PDA of premature infants (including extremely low birthweight, <1000 g) have become available and several trials have demonstrated successful and safe transcatheter PDA closure (TCPC) in this population. Whether TCPC represents a paradigm shift in PDA management that will result in improved short- and long-term outcomes, less bronchopulmonary dysplasia, improved neurodevelopment, or better long term renal function remains to be seen. Careful rigorous study of the potential benefits of TCPC in this highly vulnerable population in the context of well-designed adequately powered trials is needed prior to widespread adoption of this approach.

Abstract
BACKGROUND Video-assisted thoracoscopic surgery for patent ductus arteriosus (VATS-PDA) is an alternative surgical procedure to open chest surgery, even in premature infants. This study investigated whether the timing of VATS-PDA has a prognostic impact in premature infants whose operative indication was determined according to the symptomatic PDA and the ineffectiveness of or contraindication to indomethacine therapy. METHODS We studied 49 infants born at or before 28 weeks of gestation who were admitted to the neonatal intensive care unit between January 2004 and June 2016, and who underwent VATS-PDA. The patients were divided into two groups according to median age at the time of surgery (early group, 24 infants who underwent surgery at ≤ 24 days of life; late group, 25 infants who underwent surgery at ≥ 25 days of life). RESULTS No significant differences were found in bodyweight at 30 days of age and 40 weeks of corrected gestational age between the groups. The timing of surgery did not affect the operative procedure or postoperative complications. In addition, no differences were observed between the early and late groups in terms of complications associated with prematurity, including intraventricular hemorrhage, incidence and severity of bronchopulmonary dysplasia, and necrotizing enteropathy. CONCLUSION Video-assisted thoracoscopic surgery for patent ductus arteriosus can be safely performed in premature infants without a preferential timing for the intervention, suggesting that this procedure allows for an elective basis approach after heart failure management with conservative and/or drug therapy in premature infants with PDA.

Abstract
Background Less invasive procedures such as video-assisted thoracoscopic surgery (VATS) are desirable for patent ductal artery (PDA) ligation when pharmacologic or conservative approaches fail. Studies done on VATS-PDA ligation showed better outcomes when compared to open thoracotomies, however, complication rates remain conflicting. Learning curve can be a postulated reason which may also precludes the acceptability. We therefore sought to report our single centered 7-year experience of PDA closure with VATS. Methods Single centered retrospective study of 127 patients who underwent PDA ligature with VATS from February 2012 to October 2018. The cohort was divided into two groups, i.e., 2012-2014 (early phase) and 2015-2018 (late phase) and were further compared. Early and late outcomes, including mortality and morbidity, were analyzed. Results The included patients had a mean age of 1.7 years. Among them, preterm infants accounted for 38.6%, there was no operative mortality. Six deaths (4.7%) occurred during in-hospital stay, predominantly in the neonatal intensive care unit (NICU) due to massive cerebral bleeding and cardiopulmonary failure. Overall conversion rate to thoracotomy was 16.5%. It decreased from 20% in early phase to less than 5% in late phase. Fifty patients (39.4%) required transfer to the NICU. The mean in-hospital stay for the remainders was only 2.2±1.6 days. All but two patients discharged home survived follow-up period without any adverse events and nobody among non-converted cases expressed concerns regarding chest deformity. A 5-year probability of survival estimated according to the Kaplan-Meier curve was 93.6%. Conclusions VATS is a safe as well as efficient method for closure of PDA that ensures satisfactory late cosmetic results. Postoperative mortality and extended hospital stay may be attributed to prematurity. Although learning curve exists it does not affect the safety and late outcomes.

Incidence, Risk Factors, and Comorbidities of Vocal Cord Paralysis After Surgical Closure of a Patent Ductus Arteriosus: A Meta-analysis. Pediatr Cardiol 2019; 40:116-125. [PMID: 30167748 PMCID: PMC6348263 DOI: 10.1007/s00246-018-1967-8] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Accepted: 08/16/2018] [Indexed: 12/15/2022]
Abstract
Surgical closure of a patent ductus arteriosus (PDA) is considered standard treatment for symptomatic neonates refractory to medical therapy. Sometimes, iatrogenic injury to the left recurrent laryngeal nerve during the procedure can result in vocal cord paralysis (VCP). This study aimed to estimate the incidence of VCP in patients after surgical PDA closure and to identify any associated risk factors and morbidities associated with VCP in the preterm infant population. A thorough search of the major electronic databases was conducted to identify studies eligible for inclusion into this meta-analysis. Studies reporting data on the incidence of VCP (primary outcomes) or risk factors and morbidities associated with VCP in premature infant population (secondary outcomes) were included. A total of 33 studies (n = 4887 patients) were included into the analysis. Overall pooled incidence estimate of VCP was 7.9% (95%CI 5.3-10.9). The incidence of VCP after PDA closure was significantly much higher in premature infants (11.2% [95%CI 7.0-16.3]) than in non-premature patients (3.0% [95%CI 1.5-4.9]). The data showed that VCP was most common after surgical ligation and in studies conducting universal laryngoscopy scoping. The risk factors for postoperative VCP in preterm infants included birth weight and gestational age. In addition, VCP was significantly associated with the occurrence of bronchopulmonary dysplasia, gastrostomy tube insertion, and increased duration of mechanical ventilation. Vocal cord paralysis remains a frequent complication of surgical closure of a PDA, especially in premature neonates, and is associated with significant post-procedural complications.

Abstract
Introduction Posterolateral thoracotomy was the access of choice in surgical treatment of patent ductus arteriosus (PDA) for many years before the introduction of video-assisted thoracoscopic surgery (VATS). The latter is thought to reduce postoperative pain and improve musculoskeletal system status. However, it carries a potential risk of conversion to thoracotomy. Aim To evaluate the rate, reasons and outcomes of VATS conversion to thoracotomy in surgical PDA patients. Material and methods From 2012 to 2017, 112 children were qualified for VATS closure of symptomatic PDA. Among them, 19 (16.9%) with the median age of 19.4 months required conversion to thoracotomy. The predominant reasons for conversion, early mortality and morbidity as well as late survival were evaluated. Results The overall conversion rate was 16.9% with an evident learning curve as it decreased significantly from more than 20% at the beginning to approximately 10% in the last 2 years. The predominant reasons were incomplete PDA closure (n = 6; 31.6%) followed by ductal bleeding after clip application (n = 5; 26.3%) and inadequate visualization (n = 5). One child died 48 h after the surgery due to acute cardiopulmonary failure (mortality 5.9%). All patients required postoperative chest tube insertion, and two of them developed postoperative pneumothorax. Neither deaths nor severe adverse events were noted throughout the follow-up period. Conclusions The rate of VATS PDA closure conversion to standard thoracotomy features a learning curve. Although it must be considered as a serious complication, probably it does not negatively affect either early the mortality rate or long-term survival.

Abstract
CONTEXT Extremely premature (EP) infants are at increased risk of left vocal cord paralysis (LVCP) following surgery for patent ductus arteriosus (PDA). OBJECTIVE A Systematical Review was conducted to investigate the incidence and outcomes of LVCP after PDA ligation in EP born infants. DATA SOURCES Searches were performed in Cochrane, Medline, Embase, Cinahl and PsycInfo. STUDY SELECTION Studies describing EP infants undergoing PDA surgery and reporting incidence of LVCP were included. DATA EXTRACTION AND SYNTHESIS Study details, demographics, incidence of LVCP, diagnostic method and reported outcomes were extracted. DerSimonian and Laird random effect models with inverse variance weighting were used for all analyses. STUDY APPRAISAL The Newcastle-Ottawa scale for observational studies was used for quality assessment. RESULTS 21 publications including 2067 infants were studied. The overall pooled summary estimate of LVCP incidence was 9.0% (95% CI 5.0, 15.0). However, the pooled incidence increased to 32% when only infants examined with laryngoscopy were included. The overall risk ratio for negative outcomes was higher in the LVCP group (2.20, 95% CI 1.69, 2.88, p = 0.01) compared to the non-LVCP-group. CONCLUSIONS Reported incidence of LVCP varies widely. This may be explained by differences in study designs and lack of routine vocal cords postoperative assessment. LVCP is associated with negative outcomes in EP infants. The understanding of long-term outcomes is scarce. Routine laryngoscopy may be necessary to identify all cases of LVCP, and to provide correct handling for infants with LVCP.

Abstract
A patent ductus arteriosus is a common condition, particularly in premature infants. Many spontaneously resolve but those that lead to clinical instability require closure. Conservative measures can be highly successful in selected groups. Surgical repair is effective and both open and minimally invasive approaches can be used. The minimally invasive approach may result in less long-term morbidity from a thoracotomy and may prove advantageous for these fragile infants, including less pain, shorter time on the ventilator, and shorter hospital stays.

Abstract
BACKGROUND Patent ductus arteriosus (PDA) is one of the most common congenital heart defects. Once diagnosed, an immediate pharmacologic or invasive treatment should be performed. The purpose of this work was to evaluate the safety and efficacy of surgical PDA ligation in children using video-assisted thoracoscopic surgery (VATS) in comparison with a conventional muscle-sparing posterolateral thoracotomy technique (MSPLT). MATERIALS AND METHODS In this single-center, retrospective study 173 children qualified for surgical PDA closure were enrolled. Patients were divided according to their weight and type of surgery performed. The groups consisted of patients operated through thoracotomy (54%) or VATS (46%). Operative characteristics, cosmetic effect, postoperative complications and long-term survival were evaluated. RESULTS Regardless of weight, fewer complications were noted in children after thoracoscopic clipping. Fifteen VATS patients required intraoperative conversion to thoracotomy; however, adverse sequelae were not observed. Aesthetics seemed to be the major complaint after conventional surgery. We did not observe any statistically significant differences in the long-term survival between both groups. CONCLUSIONS Both techniques were shown to be safe and effective. Unsuccessfully performed thoracoscopic surgeries were safely converted to conventional thoracotomy. VATS, being a less invasive approach, leads to a better aesthetic effect and lower surgical complication rate.

Abstract
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether thoracoscopic patent ductus arteriosus (PDA) closure is superior to conventional surgery. Altogether 821 papers were found using the reported search, 11 of which represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Eleven studies included in the analysis consisted of two prospective and three retrospective, non-randomized studies and six case series. Four included studies focused only on preterm infants, three studies enrolled neonates and the other four analysed all age groups from neonates to older children or young adults. There were no differences in mortality between video-assisted thoracoscopic surgery (VATS) and conventional surgery. Two studies suggested that VATS offers shorter operative times. Two papers observed shorter hospital stay, although the other two noted no significant difference. A large prospective trial found VATS to be associated with a lower number of postoperative complications in neonates and infants, whereas other studies suggested no significant differences in short-term postoperative complications. There is little evidence to suggest better musculoskeletal status and cosmesis in neonates following VATS. Conversion from thoracoscopy to thoracotomy described in six papers was seldom and it did not lead to any additional complications. All observational studies confirmed that both techniques are free from major adverse cardiovascular complications and these two techniques can be safely used in all patients qualified for surgical PDA closure. Two studies compared cost-effectiveness between the two techniques; one of them described VATS as significantly more cost-efficient, whereas the other study observed no difference. However, it should be noted that data were provided from different countries and time periods. The results presented suggest that there are no significant differences in early clinical outcomes between VATS and thoracotomy in all age groups. However, where differences have been shown, such as pain, postoperative complications, length of hospital and ICU stay and cost, these favour the VATS approach.

Abstract
OBJECTIVE Patent ductus arteriosus is very commonly seen in very low birth weight (VLBW) infants, affecting about one-third. The present review tries to identify the group of VLBW infants who need active intervention in day-to-day practice and to determine the mode of intervention, based on current published literatures. METHODS We searched the Cochrane library, MEDLINE, EMBASE and CINAHL databases, and reference that of identified trials. RESULTS AND CONCLUSIONS Preterm infants with a birth weight of <800g are at risk of significant morbidity and mortality from PDA; it would be reasonable to treat them when symptomatic or if requiring positive pressure ventilator support. Those weighing >800g are unlikely to need treatment unless they are ventilator-dependent or show evidence of congestive heart failure.

Abstract
Patency of the ductus arteriosus is required for fetal survival in utero. In infants born prematurely, ductus fails to close and shunt reverses from left to right. Incidence of patent ductus arteriosus (PDA) is inversely proportional to the gestational age. A large PDA (>1.5 mm diameter) with left to right shunt in very low birth weight infants can cause pulmonary edema, congestive heart failure, pulmonary hemorrhage and increase the risk for bronchopulmonary dysplasia. Attempts to prevent or close the duct by pharmacological or surgical methods have not changed the morbidity or the long term outcome. Pharmacological treatment with indomethacin or ibuprofen is successful in 75 to 80 % of infants but its use also exposes these infants to undesirable side effects like gastrointestinal bleeding, perforation and necrotizing enterocolitis. Prophylactic therapy with indomethacin or ibuprofen to prevent PDA has not altered the morbidity or long term outcome. Currently, there is a dilemma as to how to treat, when to treat and whom to treat. Recent literature suggests a trial of conservative management during the first week followed by selective use of anti-inflammatory drugs. Surgical ligation is reserved for infants who fail medical therapy and still remain symptomatic. Spontaneous closure of the PDA has been reported in up to 40-67 % of very low birth weight (VLBW) infants by 7 d. In this review authors discuss these controversies and propose a more rational approach.

Abstract
Background: Closure of tubular patent ductus arteriosus remains a challenging procedure. Anecdotal use of Amplatzer Vascular Plug IV for tubular ductus closure has been reported but feasibility and safety in a consecutive patients’ series remain unknown. Methods: We performed a monocenter prospective study at the Marie Lannelongue Hospital in Paris, France. From 2009 to 2014, a total of 47 patients (39 infants, 3 children, and 5 adults) underwent ductus closure with the Plug IV. Results: Ductus morphology was a type E in 34 (72.3%) patients and a type C in 13 (27.7%) patients. Ductus closure occurred in 39 (83.0%) infants at a median age of seven months (range: 3-23 months) and a median weight of 6.9 kg (range: 4.1-17.0 kg). A past history of prematurity and very low birth weight was found in 33 (70.2%) of them. Twelve (25.5%) patients had pulmonary hypertension. Mean Plug IV diameter was 1.9 ± 0.1 mm larger than the mean maximal ductus diameter. Early complete closure of the ductus was obtained in all patients. Early migration of an undersized Plug IV occurred in one (2.1%) patient and was suitable for percutaneous device retrieval. After a mean follow-up of 3.4 ± 1.4 years, all patients are alive and asymptomatic, no late complication occurred. Conclusion: Transcatheter closure of tubular ductus with the Amplatzer Vascular Plug IV can be safe and effective, with a 100% early occlusion rate. This device, suitable for a 4F sheath, is a new alternative for tubular ductus closure in low-body-weight infants.

Abstract
This review aims to describe the past history, present techniques and future directions in transcatheter treatment of patent ductus arteriosus (PDA). Transcatheter PDA closure is the standard of care in most cases and PDA closure is indicated in any patient with signs of left ventricular volume overload due to a ductus. In cases of left-to-right PDA with severe pulmonary arterial hypertension, closure may be performed under specific conditions. The management of clinically silent or very tiny PDAs remains highly controversial. Techniques have evolved and the transcatheter approach to PDA closure is now feasible and safe with current devices. Coils and the Amplatzer Duct Occluder are used most frequently for PDA closure worldwide, with a high occlusion rate and few complications. Transcatheter PDA closure in preterm or low-bodyweight infants remains a highly challenging procedure and further device and catheter design development is indicated before transcatheter closure is the treatment of choice in this delicate patient population. The evolution of transcatheter PDA closure from just 40 years ago with 18F sheaths to device delivery via a 3F sheath is remarkable and it is anticipated that further improvements will result in better safety and efficacy of transcatheter PDA closure techniques.

Abstract
More than three decades have passed since the introduction of transcatheter devices for closure of patent ductus arteriosus, and many occluders have been made available since then. The ideal requirements of any procedure are a user-friendly technique, optimum success rate, no residual anomaly, minimal morbidity/mortality, and comparability or superiority to the existing conventional modality of treatment. With various advancements in device design, delivery and assisted systems, the tremendous procedural safety and effectiveness, along with low cost and widespread availability of these devices makes transcatheter closure of patent ductus arteriosus a preferred therapeutic modality in all age groups, with decreasing demographic trends of surgical management.

Abstract
BACKGROUND Treatment for patent ductus arteriosus (PDA) in premature infants can consist of medical or surgical approaches. The appropriate therapeutic regimen remains contentious. This study evaluated the role of surgery in improving the survival of premature neonates weighing less than 1,500 g with PDA. MATERIALS AND METHODS From January 2008 to June 2011, 68 patients weighing less than 1,500 g with PDA were enrolled. The patients were divided into three groups: a group managed only by medical treatment (group I), a group requiring surgery after medical treatment (group II), and a group requiring primary surgical treatment (group III). RESULTS The rate of conversion to surgical methods due to failed medical treatment was 67.6% (25/37) in the patients with large PDA (≥2 mm in diameter). The number of patients who could be managed with medical treatment was nine which was only 20.5% (9/44) of the patients with large PDA. There was no surgery-related mortality. Group III displayed a statistically significantly low rate of development of bronchopulmonary dysplasia (BPD) (p=0.008). The mechanical ventilation time was significantly longer in group II (p=0.002). CONCLUSION Medical treatment has a high failure rate in infants weighing less than 1,500 g with PDA exceeding 2.0 mm. Surgical closure following medical treatment requires a longer mechanical ventilation time and increases the incidence of BPD. Primary surgical closure of PDA exceeding 2.0 mm in the infants weighing less than 1,500 g should be considered to reduce mortality and long-term morbidity events including BPD.

Abstract
CASE DESCRIPTION An 8-week-old female domestic shorthair cat was treated for patent ductus arteriosus (PDA) with surgical ligation. Seven weeks postoperatively, the cat was evaluated because of increased upper respiratory noise, inspiratory stridor, wheezing, and episodes of intermittent open-mouth breathing that had developed 1 week following the surgical ligation. CLINICAL FINDINGS The cat was sedated, and examination of the larynx revealed left-sided laryngeal paralysis. TREATMENT AND OUTCOME At the time left-sided laryngeal paralysis was diagnosed, the clinical signs of laryngeal dysfunction were not considered severe enough to warrant surgical intervention. No treatment was administered, and the owner monitored the cat for respiratory distress and worsening of clinical signs for an additional 5 months. During those 5 months, the clinical signs improved but persisted. Seven months after PDA ligation, the cat was again sedated and the larynx examined. The examination revealed persistent left arytenoid dysfunction, which was believed to be the result of permanent damage to the recurrent laryngeal nerve that was sustained during the surgical ligation of the PDA. The owner was counseled about surgical and medical treatment options for laryngeal paralysis but elected to forego treatment at that time. CLINICAL RELEVANCE Unilateral laryngeal paralysis caused by iatrogenic damage to the recurrent laryngeal nerve is a potential complication subsequent to surgical ligation of a PDA. The frequency of iatrogenically induced laryngeal paralysis is likely underestimated in small animal patients. Laryngoscopy should be performed in any small animal with a history of PDA attenuation and clinical signs of respiratory tract disease.

Abstract
AIM To present a modified and safe technique of thoracoscopic clipping of patent ductus arteriosus (PDA) in children and its early outcomes. PATIENTS AND METHODS Patients are anesthetized, ventilated via single-lung ventilation, and placed in a right lateral position. The surgeon and the assistant stand at the patient's feet, and a monitor is placed at the patient's head. The ductus is pulled forward with a Vicryl(®) (Ethicon) thread and clipped completely. RESULTS From May 2010 to February 2011, 58 patients with PDA (27 boys and 31 girls) were operated on using the same technique. Patients' ages varied from 8 days to 36 months. Mean weight of patients was 5.9±2.8 kg (range, 2.1-10 kg). Mean operative time was 33±12 minutes (range, 15-90 minutes). There were no intraoperative complications. Postoperative complications occurred in 2 patients: 1 patient developed a pneumothorax, and 1 patient had pleural effusion. Mean postoperative stay was 4.1±2.1 days for patients >3 months old and 11.9±8.4 days for patients ≤3 months old. No injuries of recurrent laryngeal nerve occurred in any patients, and there were no residual shunts in any patients 3-6 months after discharge. CONCLUSION A modified technique of thoracoscopic closure is a safe and effective procedure for PDA in children.

Abstract
OBJECTIVES Video-assisted thoracoscopic surgery (VATS) has become a standard procedure in pediatric surgery. To facilitate surgical access, the dependent lung has to collapse using intrathoracic carbon dioxide insufflation and/or single-lung ventilation. These procedures can induce hemodynamic deteriorations in adults. The potential impacts of single-lung ventilation in combination with capnothorax on hemodynamics in infants have never been studied before. AIM We conducted a randomized experimental study focusing on hemodynamic and respiratory changes during single-lung ventilation with or without capnothorax in a pediatric animal model. METHODS Twelve piglets were randomly assigned to receive single-lung ventilation with (SLV-CO(2) ) or without (SLV) capnothorax with an insufflation pressure of 5 mmHg for a period of two hours. Before, during, and after single-lung ventilation, hemodynamic and respiratory parameters were measured. RESULTS Although mean arterial pressure remained stable during the course of the study and no critical incidents were monitored, cardiac index (CI) decreased significantly with SLV-CO(2) (baseline 3.6 ± 1.6 l · min(-1) · m(-2) vs 2.9 ± 1.1 l · min(-1) · m(-2) at 120 min, P < 0.05). Furthermore, global end-diastolic volume and intrathoracic blood volume (ITBV) decreased as well significantly with SLV-CO(2) , causing a significant between-group difference in ITBV (P < 0.05). CONCLUSIONS Despite a decrease in CI and preload parameters, the combination of single-lung ventilation and low-pressure capnothorax was well tolerated in piglets and could justify further clinical studies to be performed in infants and children focusing on hemodynamic and respiratory changes during VATS.

Abstract
The current study was designed to compare long-term clinical outcomes and costs between video-assisted thoracoscopic surgery (VATS) and transcatheter Amplatzer occlusion (TAO). This study enrolled 294 patients with isolated patent ductus arteriosus (PDA) from April 2002 to April 2007, and 290 of these patients were followed up until April 2010. Of the 294 patients, 196 underwent VATS and 98 accepted TAO for PDA closure. The two groups were similar in terms of demographics and preoperative clinical characteristics. No cardiac deaths occurred in either group. All the patients in the VATS group had successful PDA closure, and 94 patients (94/98, 95.9%) in the TAO group had successful PDA occlusion. The incidence of acute procedure-related complications recorded was 1.5% in the VATS group compared with 10.2% in TAO group (P < 0.05). The cost per patient was $1,309.40 ± $312.20 in the VATS group and $3,415.80 ± $637.30 in the TAO group (P < 0.05). There were no cardiac deaths or newly occurring arrhythmias in either group during the fellow-up period. Up to the latest follow-up, no late recanalization or residual shunting was documented, and heart structure returned to normal level in the VATS group. However, residual shunting was detected in four more TAO patients. This study confirmed the long-term safety and efficacy of VATS clipping of PDA. Compared with TAO, PDA interrupted with VATS can achieve both excellent clinical results and satisfying cost effectiveness. The cost for VATS is only a little more than one third the cost for TAO.

Abstract
This study was designed to compare the long-term clinical outcomes and costs between video-assisted thoracic surgery (VATS) and posterolateral thoracotomy (PT) in neonates and infants. This study enrolled 302 patients with isolated patent ductus arteriosus (PDA) from January 2002 to 2007 and followed them up until April 2010. A total of 134 patients underwent total VATS (VATS group), and 168 underwent PDA closure through PT (PT group). The two groups were compared according to clinical outcomes and costs. The demographics and preoperative clinical characteristics of the patients were similar in the two groups. No cardiac deaths occurred, and the closure rate was 100% successful in both groups. The operating, recovery, and pleural fluid drainage times were significantly shorter in the VATS group than in the PT group. Statistically significant differences in length of incision, postoperative temperature, and acute procedure-related complications were observed between the two groups. The cost was $1,150.3 ± $221.2 for the VATS group and $2415.8 ± $345.2 for the PT group (P < 0.05). No cardiac deaths or newly occurring arrhythmias were detected in either group during the follow-up period. Statistically significant differences in the rate of residual shunt and scoliosis were observed between the two groups. The left ventricular end-diastolic diameter and the pulmonary artery diameter could be restored to normal in the VATS group but not in the PT group. The study confirmed that VATS offers a minimally traumatic, safe, and effective technique for PDA interruption in neonates and infants.

Abstract
BACKGROUND Video-assisted thoracoscopic surgery (VATS) has emerged as an innovative and popular procedure for closure of a patent ductus arteriosus (PDA), but is associated with a minute rate of residual or recurrent duct patency. This study aims to analyze the efficacy of intraoperative esophageal stethoscopic monitoring in reducing the incidence of residual ductal flow during PDA clipping by VATS. METHODS Between June 1997 and October 2009, we retrospectively assessed 2000 consecutive patients with PDA who underwent VATS. During the procedure, heart sounds were monitored by the anesthesiologist through an esophageal stethoscope. Changes in continuous cardiac murmurs were recorded before and after the PDA clipping and were confirmed to disappear completely. Color flow Doppler echocardiography was performed immediately before discharge, and patients were followed monthly for 3, 6, and 12 months and then annually to confirm the absence of residual or recurrent shunt. RESULTS Mean age was 6.0 years (range, 1 month-35 years), mean weight was 11.1 kg (range, 6-65 kg), and mean PDA diameter was 5.5 mm (range, 3-9 mm). Ninety-two percent of patients showed no ductal flow after a single clipping. In the other 8% of patients, residual flow was detected intraoperatively after a single clipping, but was eliminated by the second clipping. Twelve patients (0.6%) presented with residual ductal flow immediately after the operation (detected by color Doppler echocardiography), which was eliminated by thoracotomy before discharge. All patients left the hospital with echocardiography documenting no evidence of residual PDA. At follow-up, the incidence of residual patency was 0.2% (4 of 2000). CONCLUSIONS Our results demonstrate that the intraoperative esophageal stethoscope provides a remarkably effective technique for monitoring and evaluating PDA ligation by VATS, thus avoiding reintervention and the complications associated with residual ductal flow in most cases.

Abstract
The surgical closure of patent ductus arteriosus (PDA) is provided more frequently in extremely low birth weight babies who are usually deemed unsuitable for pharmacological closure. We have adopted subaxillary mini-thoracotomy in order to lessen surgical trauma in these babies; and its clinical results were analyzed. From April 2004 to August 2008, out of 50 babies at the neonatal intensive care unit who underwent the surgical closure of PDA, 22 premature babies weighing less than 1 kg at operation were included in the study. Eleven babies were males and mean gestational age was 27 weeks ranging from 23(+3) to 30(+2) weeks. Mean body weight at operation was 816 g ranging from 490 to 989 g and average age at operation was 17.9+/-11.9 days. Of them, 17 babies (72%) were ventilator dependent preoperatively, as compared with 13 out of 28 (46%) babies that weighed more than 1 kg (P<0.05). Four babies did not survive to discharge. Among 28 babies who were heavier than 1 kg, there were only one death. However, the mortality difference was not statistically significant (P=0.11). All mortalities were caused by inherent problems of prematurity and co-morbidities. Out of 17 babies who had been ventilator dependent preoperatively, 13 weaned off successfully at 17.0+/-23.9 days after the operation. The baby patients heavier than 1 kg weaned at 6.0+/-5.3 days (P=0.27). Surgical outcome of simple and less invasive subaxillary mini-thoracotomy was satisfactory; the surgery is highly recommended for ductal closure in extremely low weight premature babies.

Abstract
Patent arterial duct (PAD) is a congenital heart abnormality defined as persistent patency in term infants older than three months. Isolated PAD is found in around 1 in 2000 full term infants. A higher prevalence is found in preterm infants, especially those with low birth weight. The female to male ratio is 2:1. Most patients are asymptomatic when the duct is small. With a moderate-to-large duct, a characteristic continuous heart murmur (loudest in the left upper chest or infraclavicular area) is typical. The precordium may be hyperactive and peripheral pulses are bounding with a wide pulse pressure. Tachycardia, exertional dyspnoea, laboured breathing, fatigue or poor growth are common. Large shunts may lead to failure to thrive, recurrent infection of the upper respiratory tract and congestive heart failure. In the majority of cases of PAD there is no identifiable cause. Persistence of the duct is associated with chromosomal aberrations, asphyxia at birth, birth at high altitude and congenital rubella. Occasional cases are associated with specific genetic defects (trisomy 21 and 18, and the Rubinstein-Taybi and CHARGE syndromes). Familial occurrence of PAD is uncommon and the usual mechanism of inheritance is considered to be polygenic with a recurrence risk of 3%. Rare families with isolated PAD have been described in which the mode of inheritance appears to be dominant or recessive. Familial incidence of PAD has also been linked to Char syndrome, familial thoracic aortic aneurysm/dissection associated with patent arterial duct, and familial patent arterial duct and bicuspid aortic valve associated with hand abnormalities. Diagnosis is based on clinical examination and confirmed with transthoracic echocardiography. Assessment of ductal blood flow can be made using colour flow mapping and pulsed wave Doppler. Antenatal diagnosis is not possible, as PAD is a normal structure during antenatal life. Conditions with signs and symptoms of pulmonary overcirculation secondary to a left-to-right shunt must be excluded. Coronary, systemic and pulmonary arteriovenous fistula, peripheral pulmonary stenosis and ventricular septal defect with aortic regurgitation and collateral vessels must be differentiated from PAD on echocardiogram. In preterm infants with symptomatic heart failure secondary to PAD, treatment may be achieved by surgical ligation or with medical therapy blocking prostaglandin synthesis (indomethacin or ibuprofen). Transcatheter closure of the duct is usually indicated in older children. PAD in preterm and low birth weight infants is associated with significant co-morbidity and mortality due to haemodynamic instability. Asymptomatic patients with a small duct have a normal vital prognosis but have a lifetime risk of endocarditis. Patients with moderate-to-large ducts with significant haemodynamic alterations may develop irreversible changes to pulmonary vascularity and pulmonary hypertension.

Abstract
Patent ductus arteriosus (PDA) ligation is a potentially lifesaving procedure that is frequently performed in very low-birth-weight (VLBW) infants. Video-assisted thoracoscopic surgery (VATS) PDA ligation has many advantages; however, this approach has not been widely used in these extremely small patients. We present a technique using a novel retractor that allows safe VATS PDA ligation in the VLBW neonate. A 740-g male infant with necrotizing enterocolitis underwent general anesthesia. After placement in the right lateral decubitus position, he underwent a left VATS PDA ligation using a new 3-mm fan retractor for lung retraction and exposure. A thoracostomy tube was not used. He recovered uneventfully and is well at 6-month follow-up. The technique is minimally invasive and provides superior visualization of the PDA and surrounding anatomical landmarks. Using this novel retractor, VATS PDA ligation is practical in even the smallest infants. This retractor may facilitate the performance of more advanced thoracoscopic procedures in VLBW infants.

Abstract
Management of patent ductus arteriosus (PDA) in premature neonates has always been a challenge to the neonatologist and continues to be a controversial topic. Indications for treatment are not clear. Approximately 40% of ductus arteriosus close spontaneously even in extremely-low-birth-weight neonates. Prophylactic or early pre-symptomatic treatment may unnecessarily expose these babies, in whom the ductus might close spontaneously, to pharmacologic agents and their adverse effects. On the other hand, with advancing postnatal age, delaying treatment could potentially decrease successful medical closure thereby increasing the rate of surgical ligation and the complications associated with surgery. We tried to develop some clinical guidelines for management of PDA in premature neonates based on evidence, or lack thereof, and experience.

Abstract
There is a significant rate of residual or recurrent ductal patency after video-assisted thoracoscopic closure of patent ductus arteriosus. Between February 2000 and October 2004, this procedure was carried out on 145 consecutive patients in whom heart sounds were monitored intraoperatively with an esophageal stethoscope. Changes in continuous cardiac murmurs were recorded after placing the 1(st) and 2(nd) vascular clips. There was no ductal flow after clipping twice in 138 (95%) patients; in the other 7, residual flow was abolished at the 3(rd) attempt. All patients left the operating room with no residual ductal patency on echocardiography. After 6 months, there was no incidence of residual patency. Intraoperative esophageal stethoscopy provides remarkably loud and clear heart sounds for direct monitoring and reliable evaluation of the entire course of thoracoscopic patent ductus arteriosus closure, without interrupting the surgical procedure, thus avoiding re-intervention and complications associated with residual ductal flow.

Abstract
BACKGROUND Video-assisted thoracoscopic surgery (VATS) has been shown to be a safe and effective method of closing patent ductus arteriosus (PDA). We retrospectively studied our series of patients with PDA who underwent VATS closure with new modifications. METHODS From June 1997 to December 2004, 1,300 consecutive patients diagnosed with PDA (mean age, 6 years) were referred to us, and all of them met our inclusion criteria for the VATS procedure. Recently, we made some minor alterations to our routine methodology. After complete closure of PDA by two titanium clips, the extubated patient leaves the operating room without a chest tube. RESULTS There were 3 cases of chylothorax, which were successfully treated by thoracotomy and ligation of the small lymphatic ducts after 1 week of close observation. The procedure was changed to thoracotomy in 7 patients. Meanwhile, 5 additional patients had transient recurrent laryngeal nerve dysfunction. All cases were reassessed immediately after the procedure, and followed for more than 7 years by control echocardiography. No significant complication or residual shunt was recorded during the follow-up period. Mean procedure time was about 10 +/- 2 minutes. All patients were discharged shortly after the procedure (about 20 hours). CONCLUSIONS Based on this experience, VATS appears to be safer and more effective as well as having other advantages such as being simple to perform, quick, and comfortable for the patients. Furthermore, the cosmetic benefits also make it appropriate as an outpatient procedure.

Abstract
Surgical ligation of a patent ductus arteriosus (PDA) in small premature infants may be performed with open thoracotomy or video-assisted thoracoscopic surgery (VATS). The LigaSure vessel sealing system (Valleylab/Tyco Healthcare, Boulder, CO) is increasingly being used because of its effectiveness in promoting coagulation. Moreover, for PDA ligation using VATS, the LigaSure system seems more practical than vascular clips. Among 81 children, including 43 premature infants weighing less than 1000 grams operated on for PDA in our institution, one 9-month-old boy weighing 7600 grams underwent PDA ligation using a LigaSure grasp. The perioperative aspect of the closed ductus was satisfactory. The following day, however, ultrasound control revealed recanalization of the ductus, and the child had to undergo a second operation. At operation, the ductus wall adventia and media appeared to have retracted to both extremities, leaving the intima exposed and pulsating under the blood pressure. The PDA ligation was repeated, but in conditions of severe hemorrhage. The LigaSure system works by fusing collagen in the tissue. However, because the ductus wall has less collagen than any other vessels in the body, the LigaSure vessel sealing system is not reliable for PDA ligation.

Abstract
PURPOSE Patent ductus arteriosus (PDA) ligation in premature infants has been shown to have low surgical morbidity and mortality. Ligation goals include prompt improvement in cardiorespiratory failure, with rapid wean from mechanical ventilation; less risk of prolonged mechanical ventilation and subsequent chronic lung disease (CLD); and survival to discharge. This study was designed to examine true morbidity after ligation and elucidate which preoperative factors might predict favorable outcomes. METHODS Institutional review board-approved retrospective review of 197 infants less than 38 weeks of gestational age (GA), undergoing PDA ligation via thoracotomy between January 1, 1992, and January 1, 2004. Chronic lung disease defined as need for supplemental oxygen at 36 weeks corrected GA. Student t and chi2 tests were used. RESULTS Mean GA was 27 weeks (range, 23-35 weeks), birth weight was 957 g (range, 440-3170 g); infants underwent ligation at 16 days of life (range, 1-132 days). Duration of surgery was 50.5 minutes (range, 13-150 minutes). Mean postoperative times were 27 days to extubation, 60 days to wean from supplemental oxygen, and 84 days to discharge. Early extubation (within 10 days of ligation) occurred in only 54 patients (30%). Only 44 (22%) survived to discharge without CLD. Forty patients (20%) died, with respiratory failure the most common cause (70%). In general, early extubation, survival without CLD and survival to discharge were associated with greater GA and birth weight, higher Apgar scores, greater age and weight at surgery, no preoperative intraventricular hemorrhage, lack of ventilator dependence, and lower ventilator settings (P < .05). Preoperative amount and duration of indomethacin use, chest x-ray findings, and echocardiographic assessment of ductus size did not predict favorable outcomes (all P > .05). CONCLUSIONS Most premature infants currently undergoing PDA ligation at our institution do not experience the anticipated rapid improvements in cardiorespiratory status and go on to develop CLD. Few preoperative variables (including radiographic and echocardiographic assessments) definitively predict outcomes.

Abstract
BACKGROUND/PURPOSE The aim of this study is to compare the experience with video-assisted thoracoscopic surgery (VATS) for patent ductus arteriosus (PDA) since 1995 with the results of conventional open surgery from the preceding 10 years. METHODS The records of 60 children who underwent standard posterolateral muscle splitting thoracotomy and ligation of PDA in 1986-1995 were reviewed for the study. The data on 50 children who underwent VATS PDA ligation since 1995 were collected prospectively. RESULTS All patients survived. Ductal bleeding requiring sutures with patches occurred once in the open surgery group. Two patients in the VATS group underwent immediate rethoracoscopy and clipping because of residual ductal flow in the postoperative echocardiography. Complications in the VATS group included 6 (12%) recurrent laryngeal nerve injuries (3 transient) and 2 chylothoraces. One patient in each group underwent open reoperation because of residual ductal flow 1 year after the initial operation. The operative time, duration of recovery room/neonatal intensive care unit care, duration of pleural drainage, and length of hospital stay were significantly shorter in the VATS group. CONCLUSIONS VATS PDA ligation gave results equal to traditional open surgery with a shorter operative time, faster recovery, and shorter hospital stay. More complications, especially recurrent laryngeal nerve injuries, occurred in the VATS group.

Abstract
OBJECTIVE To review our 12-year experience in video-assisted thoracoscopic surgery (VATS) for patent ductus arteriosus. METHODS VATS was performed in 743 patients. Three groups were compared: 24 low-birth-weight infants (LBWIs), 676 children between 2.5-25 kg and 43 boys > 25 kg. A diameter of > 8 mm was the main contraindication. For 85 consecutive patients, hospital stay underwent cost analysis. RESULTS Median age was 1.6 years (range 5 days-33 years) and median weight 9.0 kg (range 1.2-65 kg). Mortality was nil. Median operative time was 20 min and hospital stay 2 days. Residual patency at discharge was 0% in LBWIs, 0.7% in children, and 4.7% in boys (P = NS) and 0, 0.3, and 4.7% at follow-up (P = 0.001). Persistent recurrent laryngeal nerve dysfunction was recorded in 4.2% of LBWIs, 0.3% of children and 0% of boys (P = 0.012). Total mean cost was Euro 5954 +/- 2110. CONCLUSIONS The success rate of VATS clipping compares favorably with the thoracotomic approach but without chest wall trauma and it may have a very favorable cost-effective therapeutic balance compared to transcatheter techniques.

Abstract
BACKGROUND Surgical closure of ductus arteriosus is commonly indicated in premature newborns. The aim of this study was to assess short-term and mid-term effects of delayed surgical closure of the ductus arteriosus on respiratory and digestive outcome in extremely preterm infants. METHODS We retrospectively studied 58 infants less than 28 weeks gestational age who underwent surgical closure of ductus arteriosus between January 1997 and December 2002. Nine infants with intrauterine growth restriction and major congenital malformation were excluded from the study. Criteria for surgical closure of ductus arteriosus were: (1) medical treatment failure (ie, indomethacin or ibuprofen) and (2) hemodynamically patent ductus arteriosus: systemic arterial pressure less than gestational age in mm Hg, heart failure, left atrial-aortic root ratio greater than 1.6, mean velocity in the left pulmonary artery greater than 0.6 m/s, and ductus arteriosus diameter greater than 3 mm. Infants were divided into two groups: (1) the early group who had surgery before 21 days of life (n = 31), and (2) the late group who had surgery after 21 days of life (n = 27). Preoperative and postoperative criteria were compared between the two groups (ie, gestational age, birth weight, hemodynamic, ventilatory, and echographic [left atrial-aortic root ratio, mean velocity in the left pulmonary artery] parameters). RESULTS Preoperative gestational age and birth weight did not differ between the two groups. In the early group, gestational age was 26 weeks (range, 23 to 28 weeks and birth weight was 800 g (range, 630 to 1,240 g). In the late group, gestational age was 26 weeks (range, 24 to 28 weeks) and birth weight was 840 g (530 to 1,130 g). Hemodynamic, ventilatory, and echographic parameters were similar in both groups. Rate of bronchopulmonary dysplasia was similar in both groups. However, at 24 hours post surgery, median FiO2 was higher in the late group (28% [range, 21% to 65%]) than in early group (21% [range, 21% to 60%]) (p < 0.05). Furthermore, full oral feeding was acquired later in the late group (57 days of life [range, 30 to 136 days]) than in the early group (37 days of life [range, 27 to 84 days]) (p < 0.01), and body weight at 36 weeks of post-conceptional age was higher in the early group at 1,800 g (range, 1,250 to 2,750 g) than in the late group at 1,607 g (1,274 to 2,200 g) (p < 0.05). CONCLUSIONS Our findings show that early surgical closure of the ductus arteriosus (< 3 weeks of life) is associated with shortened delay for full oral feeding and improved body growth when compared with late surgical closure (> 3 weeks of life).

Abstract
The basis for pursuing techniques for less invasive surgery on children with congenital heart disease is to reduce the known long-term morbidities of thoracotomy and sternotomy. In addition, rapid return to normal activities, reduced length of stay, and better pain control may be achieved. Several congenital lesions have been successfully treated with innovative minimally invasive techniques; however, further technique and technology development is required to accomplish repair of the more complex defects safely and effectively.

Abstract
BACKGROUND Members of the Southern Thoracic Surgical Association (STSA) have presented important pediatric cardiothoracic surgery papers at the annual meetings over the last 50 years. In order to determine the influence of these presentations on the practice of surgery, a review was undertaken. Early papers were characterized by emerging advances in open-heart surgery, anatomic congenital heart studies, and electrophysiologic discoveries that extended life with pacemakers. Later years were characterized by innovative myocardial preservation methods, improved cardiopulmonary bypass techniques, expanded homograft availability, emphasis on accurate repairs, intraoperative transesophageal echocardiography, and cardiopulmonary transplantation. METHODS All but one of the scientific programs of the annual meetings (that of 1964) were located. The programs were reviewed and 180 presentations were identified on topics in congenital heart disease, pediatric thoracic disease, and pediatric thoracic wall abnormalities. Of those 180 oral presentations, 155 manuscripts (86%) were eventually published or in press and available for critical review and analysis. Manuscripts were grouped by diagnosis or therapeutic intervention. We determined a "cumulative citation frequency" (CCF), which measures the number of times an article is cited in the bibliography of related papers in the universe of participating journals. The selected manuscripts were compared with the historic landmark contributions and the existing trends at the time, and the number of articles both by individual authors and from institutions were tallied. RESULTS Grouping by authors and institutions showed that 100 of 155 pediatric cardiothoracic manuscripts (65%) originated from 13 institutions. The CCF for the 20 leading articles ranged from 26 to 93. CONCLUSIONS This historical STSA 50-year record of pediatric cardiothoracic advances was accomplished in a milieu of collegial respect and camaraderie. Our annual meetings over the years have provided a venue for thoracic surgeons to share their ideas, innovations, and scientific inquiry. These contributions have significantly affected the practice of pediatric cardiothoracic surgery. The STSA has worked for 50 years and we trust that it will work for another 50 years and beyond.
