Objective:To investigate the diagnostic method and value of echocardiography in screening right patent ductus arteriosus(PDA) of infants.Methods:This was a prospective study.Thirty-one infants with right PDA diagnosed by ultrasound and confirmed by prenatal ultrasonography, electronic computed tomography angiography, angiocardiography and/or surgery in Hebei Children′s Hospital from April 2014 to May 2022 were collected as research subjects, and the association of right ductus arteriosus with aortic arch anomalies and complex cardiac malformations were summarized. The diagnostic method and value of ultrasonic screening were summed up.Results:Of the 31 cases, 30 cases were correctly diagnosed by ultrasound and 1 case was misdiagnosed, who was a left aortic arch descending to the right, a crossover variation of the right and left pulmonary arteries, and a rightward displacement of the ductus arteriosus. Among these cases diagnosed correctly, 27 cases (including 24 cases with right aortic arch and 3 cases with left aortic arch) presented that ductus arteriosus was open and its ostium of pulmonary artery end was located in the proximal right pulmonary artery in views of parasternal short-axis view of great vessels at cardiac base with the combination of two dimensions and color Doppler flow imaging. Other 3 cases of right aortic arch were all single ventricle with transposition of the great artery. Due to the parallel relationship of the two great arteries, the standard parasternal short-axis view of great vessels could not be obtained, and the right ductus arteriosus was found in the high parasternal views.In all of the 27 cases with right aortic arch and right ductus arteriosus, high parasternal views showed that one end of the ductus arteriosus was connected to the right aortic arch isthmus and the other end was connected to the right pulmonary artery. In all of the 3 cases with left aortic arch and right ductus arteriosus, the high parasternal views showed that one end of the ductus arteriosus was connected to the right subclavian artery and the other end was connected to the right pulmonary artery. Among the 27 cases with right aortic arch, 16 cases were accompanied with mirror image branches, 9 cases of which had complex cardiac malformations; 10 cases were associated with aberrant left subclavian artery, 1 case of which had complex cardiac malformations; 1 case was with isolated left subclavian artery, and without complex cardiac malformations. All 3 cases of left aortic arch were accompanied with isolated right subclavian artery and none of them were associated with complex cardiac malformations. Clinical outcomes of 30 cases with right PDA: 14 cases underwent ductus arteriosus ligation due to thick ductus or other heart malformations. In other 16 cases, 4 cases were closed spontaneously, 9 cases had persistent small ductus arteriosus, and 3 cases were lost to follow-up.Conclusions:Right ductus arteriosus is mostly related to the right aortic arch, and those with mirror image branches are prone to complex cardiac malformations; cases of left aortic arch with right ductus arteriosus are tend to accompany isolated right subclavian artery. Ultrasound has an important application in the screening and diagnosis of right PDA.

Background: During hot environment work tasks with whole-body enclosed anti-bioaerosol suit, the combined effect of heavy sweating and exhaled hot humid air may cause the N95 medical respirator to saturate with water/sweat (i.e., water-blocking). Methods: 32 young male subjects with different body mass indexes (BMI) in whole-body protection (N95 medical respirator + one-piece protective suit + head covering + protective face screen + gloves + shoe covers) were asked to simulate waste collecting from each isolated room in a seven-story building at 27-28°C, and the weight, inhalation resistance (Rf), and aerosol penetration of the respirator before worn and after water-blocking were analyzed. Results: All subjects reported water-blocking asphyxia of the N95 respirators within 36-67 min of the task. When water-blocking occurred, the Rf and 10-200 nm total aerosol penetration (Pt) of the respirators reached up to 1270-1810 Pa and 17.3-23.3%, respectively, which were 10 and 8 times of that before wearing. The most penetration particle size of the respirators increased from 49-65 nm before worn to 115-154 nm under water-blocking condition, and the corresponding maximum size-dependent aerosol penetration increased from 2.5-3.5% to 20-27%. With the increase of BMI, the water-blocking occurrence time firstly increased then reduced, while the Rf, Pt, and absorbed water all increased significantly. Conclusions This study reveals respirator water-blocking and its serious negative impacts on respiratory protection. When performing moderate-to-high-load tasks with whole-body protection in a hot environment, it is recommended that respirator be replaced with a new one at least every hour to avoid water-blocking asphyxia.

Objective:To explore the echocardiographic characteristics of isolated brachiocephalic artery branches, and to analyze the reason of missed diagnosis and misdiagnosis in order to improve the diagnostic accuracy.Methods:Echocardiographic features of isolated subclavian artery and brachibrachial trunk confirmed by operation or CT angiography (CTA) or digital subtraction angiography (DSA) were retrospectively analyzed in Hebei Children′s Hospital from May 2017 to July 2021. Related literatures of other rare types of isolated brachiocephalic artery branches retrieved in PubMed were reviewed, and the echocardiographic characteristics of such vascular malformations were summarized.Results:A total of 4 children with isolated brachiocephalic artery branches were included. Echocardiography correctly diagnosed isolated brachiocebrachial trunk in 1 case and missed or misdiagnosis in 3 cases, including isolated subclavian artery was missed in 1 case, isolated subclavian artery was misdiagnosed as aberrant subclavian artery in 1 case and patent ductus arteriosus in 1 case. A total of 105 cases of isolated brachiocephalic artery branches were reviewed, including isolated brachiocephalic artery in 31 cases (53.3%), isolated common carotid artery in 15 cases (29.5%), isolated common carotid artery in 15 cases (14.3%) and isolated internal carotid artery in 3 cases (2.9%). The characteristic of echocardiography was that the brachiocephalic branch of the aortic arch was disconnected from the aortic arch, often via the ductus arteriosus or directly connected to the bifurcation of the pulmonary artery.Conclusions:Isolated brachiocephalic artery branches have certain characteristic echocardiographic features and these kinds of vascular malformations are accompanied by different degrees of stealing blood phenomenon. Careful tracing of the origin of brachiocephalic artery branches and combined with cervical vascular ultrasound when necessary can improve the diagnosis rate of isolated brachiocephalic artery branch lesions.

Objective:To investigate the feasibility of "twelve-section ultrasonic screening diagnosis method" in screening for neonatal complex congenital heart disease (CHD) in primary hospitals.Methods:This is a prospective study. A total of 71 580 newborns were screened for CHD using the "twelve-section ultrasonic screening diagnosis method" from four pilot units in Hebei province, which were Bo'ai Hospital of Huanghua Development Zone, Traditional Chinese Medicine Hospital of Fengning County, Maternity & Child Healthcare Hospital of Tang Country, and Maternity & Child Healthcare Hospital of Rongcheng Country, from November 2015 to December 2019. Another 262 children with CHD were enrolled, including 39 with complex CHD. These cases received ultrasonography at four pilot units above and then were transferred to CHD Screening Diagnosis and Treatment Center of Hebei Children's Hospital (our center) prior to the implementation of "twelve-section ultrasonic screening diagnosis method" from June 2012 to June 2014, who were all confirmed by surgery. Set the diagnosis results of our center as the gold standard, the sensitivity, specificity, and diagnostic consistency rate in screening for complex CHD cases were calculated. Receiver operating characteristic (ROC) analysis and Chi-square test were used to compare and analyze the sensitivity for screening neonatal complex CHD before and after implementing the method. The screening results of complex CHD after implementing the method between the pilot units and our center as well as between the four pilot units were compared and analyzed using Chi-square test. Results:A total of 553 (0.77%) CHD cases were detected by the "twelve-section ultrasound screening diagnosis method", including 66 cases of complex CHD and 487 cases simple CHD. Among the cases screened using the method, there were three false negative cases (one case with total anomalous pulmonary venous drainage, one with abnormal coronary artery originating from pulmonary artery, and one with atresia of distal to the left subclavian artery, aortic arch and left aortic arch of double-arch), one false positive case (false echo loss of aortopulmonary septal that was misdiagnosed as aortopulmonary septal defect), five cases of misdiagnosis (one common pulmonary venous atresia case that was misdiagnosed as total anomalous pulmonary venous drainage, one persistent stenosis of the fifth aortic arch that was misdiagnosed as coarctation of aorta, one pulmonary artery sling that was misdiagnosed as absence of left pulmonary artery, one severe coarctation of aorta that was misdiagnosed as interruption of aortic arch, and one aortic isthmus atresia that was misdiagnosed as coarctation of aorta), and all were complex CHD cases. A total of 68 cases (12.3%) of complex CHD were confirmed by our center. The overall sensitivity, specificity, and diagnostic consistency rate of screening were 95.6% (65/68), 99.8% (484/485), and 86.8% (59/68), respectively and the area under ROC curve was 0.98. Before the implementation, the overall sensitivity, specificity, and diagnostic coincidence rates of ultrasonic screening for complex CHD were 69.2%(27/39), 95.5%(213/223), and 61.5% (24/39), respectively, and the area under ROC curve was 0.82. The sensitivity of complex CHD screening was significantly increased after implementing the method ( χ2=14.28, P<0.05). There was no significant statistical significance in the sensitivity for screening complex CHD after the implementation between the pilots and our center or between the four pilots (all P>0.05). Conclusions:"Twelve-section ultrasonic screening diagnosis method" is suitable for the screening of neonatal complex CHD in hospitals at the county level. However patients with some special types of complex CHD are recommended to be transferred for a more accurate diagnosis.

Objective:To analysis the prognosis related factors of patients with small cell cancer of the esophagogastric junction treated by surgery.Methods:The clinicopathologic data of 129 patients with small cell cancer of the esophagogastric junction underwent surgery treatment in the Fourth Hospital of Hebei Medical University from January 2004 to December 2010 were retrospectively analyzed. Univariate survival survival was performed by Kaplan-Meier method and Log rank test. Multivariate survival was analyzed by using Cox proportional hazard model.Results:Radical surgery was performed in 123 patients, whereas other 6 cases were conducted palliative operation. The 5-year overall survival (OS) rate of this cohort was 21.0% and median survival time was 25.7 months. The 5-year progression free survival (PFS) rate of this cohort was 11.0% and median PFS time was 19.1 months. The univariate analysis result showed that operation manner, radical or not, tumor length, lymph node metastasis, TNM stage, intravascular cancer embolus surgical margin positive or not, the expression of Syn, comprehensive treatment and radiochemotherapy after progression were associated with the OS of these patients ( P<0.05). Multivariate analysis result showed that lymph node metastasis, radiochemotherapy after progression were independent risk factors of OS ( P<0.05). Univariate analysis result showed that operation manner, radical or not, tumor length, TNM stage, lymph node metastasis, intravascular cancer embolus, surgical margin positive or not, the expression of Syn, comprehensive treatment and radiochemotherapy after progression were associated with PFS ( P<0.05). Multivariate analysis showed that lymph node metastasis and radiochemotherapy after progression were independent risk factors of PFS ( P<0.05). Conclusions:The prognosis of small cell cancer of the esophagogastric junction patients remains poor. Lymph node metastasis and radiochemotherapy after progression are regarded as independent prognostic factors of these patients.

Objective:To analyze the clinical characteristics and treatment of tricuspid valve prolapse caused by chordal rupture complicated with persistent pulmonary hypertension in neonates.Methods:The clinical data of a male neonate with tricuspid valve prolapse complicated with persistent pulmonary hypertension admitted to the Neonatal Intensive Care Unit of Children′s Hospital of Hebei Province in November 2018 was analyzed retrospectively. Related literature up to September 2020 was searched with the strategy of "(neonate OR newborn) AND (tricuspid valve prolapse) AND (rupture OR necrosis) AND (papillary muscle OR chordae tendineae) AND (pulmonary hypertension)" in Wanfang, CNKI and PubMed database in Chinese and English. The characteristics of the disease were summarized.Results:A male full-term neonate was admitted due to presenting severe cyanosis for 9 hours. He was born by caesarean section and presented severe cyanosis and dyspnea at 10 min of ages, unresponsive to the positive airway pressure resuscitation. After 9 hours of mechanical ventilation, there was no improvement. Thus he was transferred to Children′s Hospital of Hebei Province. On admission, the initial blood gas analysis showed an arterial partial pressure of oxygen of 22.5 mmHg (1 mmHg=0.133 kPa). The echocardiography revealed prolapsed anterior leaflet of tricuspid valve, severe tricuspid regurgitation (TR) and pulmonary artery hypertension, and right to left shunt via a patent foramen ovale. The arterial duct was closed. The chest X-ray was normal. The boy was treated with nitric oxide, milrinone, and continued mechanical ventilation initially. Addition of prostacyclin analog (treprostinil) on day 3 led to significant improvement of pulmonary blood flow, oxygenation, and stabilization, so that the extracorporeal membrane oxygenation therapy was avoided. At 11 months after birth, the boy underwent cardiac surgery. At surgery, the rupture of chordal tendineae in anterior leaflet of tricuspid valve was found. Tricuspid annuloplasty, valvuloplasty and repair of patent foramen ovale were successfully performed. The follow-up echocardiogram at postoperative 3 months showed only mild tricuspid insufficiency. The boy was well at last follow-up at 22 months of age with normal cognitive skill development. According to literature, 20 cases of papillary muscle or chordae tendineae rupture in neonates had been reported in 12 English papers. Among the total 21 neonates, there were 12 male infants and only one premature infant with gestational age of 33 weeks. They presented with profound cyanosis soon after birth. All of them received endotracheal intubation and mechanical ventilation. Other treatments included inhalation of nitric oxide, intravenous milrinone, vasoactive drugs, diuretics and prostacyclin, etc. Extracorporeal membrane oxygenation (ECMO) was used in 6 infants as a bridge to surgical treatment. Two cases reported earlier death of cardiopulmonary failure without operation and the rest 19 survived after surgery. The followed surgery or autopsy revealed that all of them had tricuspid valve prolapse, rupture of papillary muscle or chordae tendineae.Conclusions:The severe TR resulting from rupture of papillary muscle or chordate tendineae in neonates is rare and could cause severe hypoxemia. Early recognition, adequate cardiopulmonary support to stabilize the hemodynamic status and timely surgery can significantly reduce the mortality.

Objective:To investigate the feasibility and safety of submaximal balloon dilation and to perform small-diameter stent for symptomatic carotid artery severely stenosis before coronary artery bypass grafting(CABG).Methods:From January 2016 to December 2019, 30 patients of the Department of Neurointervention in Beijing Anzhen Hospital with symptomatic carotid artery stenosis(≥70%) and the left main trunk or triple-vessel of coronary artery disease were analyzed retrospectively. General information, clinical characteristics, and imaging data of all cases were collected. All patients underwent submaximal balloon dilation and small-diameter stent implantation. Preoperative comorbidities or risk factors included hypertension 23 cases(76.7%), diabetes 10 cases(33.3%), hyperglycemia 14 cases(46.7%), moking 13 cases(43.3%). Left main trunk disease 6 cases(20.0%), three-vessels disease 24 cases(80.0%), mitral regurgitation 1 case(3.3%), stable angina 25 cases(83.3%), myocardial infarction 8 cases(26.7%), cerebral infarction 24 cases(80.0%) and transient ischemia attack(TIA) 6 cases(20.0%) caused by ipsilateral carotid artery stenosis. The median National Institutes of Health Stroke Scale(NIHSS) score was 2(0-3), and the median modified Rankin Scale(mRS) score was 1(0-1) before the operation. The mean interval between carotid artery intervention and CABG was(23.4±8.2)days.Results:29 cases(96.7%, 29/30) underwent CAS-CABG operation successfully. In one case of carotid artery extreme tortuosity, the emboli protective device could not place the distal carotid artery. In the operative procedure, 27 cases(90.0%, 27/30) underwent with 3mm diameter balloon, only 3 cases(10.0%) with 3 mm balloon after pre-dilatation with 2 mm diameter balloon because of severely high-grade stenosis(99%). 25 cases(83.3%) with 7mm diameter stents and 5 cases(16.7%) with 6 mm diameter stents, including 22 cases(73.3%) with a closed-cell stent and 8 cases(26.7%) with an open-cell stent. In the perioperative period, the heart rate of two patients was lower than 50 BPM during operation and returned to normal after using atropine immediately. Another patient presented with chest tightness during interventional therapy. TNI elevation was examined urgently. After oxygen inhalation and intravenous infusion of Nitroglycerin, the patient's symptoms improved rapidly. No cardiac and cerebrovascular complications occurred during the perioperative period of CABG, no cardiac-related complications occurred within 30 days of follow-up, one case of TIA and 1 case of cerebral infarction. After intensive anti-platelet aggregation and lipid-lowering treatment, two patient's symptoms improved. There were no death cases in all patients during carotid artery interventional therapy, perioperative CABG and 30-day follow-up. Thirty days later, we performed a clinical follow-up of 23 cases, median 4.5(3.0-7.9) months, mRS Score Median 1(0-1). One patient presented with TIA, any patient had no symptoms of the cardiac or nervous system. Image follow-up of 17 cases, median 3.5(2.8-4.5) months, carotid artery ultrasound showed in-stent restenosis(stenosis rate>50%) in 1 case, the patient was asymptomatic restenosis, continue treatment of aggressive anti-platelet and lipid-lowering drugs.Conclusion:Submaximal balloon dilation and performing small-diameter stent for symptomatic carotid artery severely stenosis before CABG is safe and feasible, which could not only reduce the incidence of vagus reflex resulted in acute coronary syndrome during carotid artery stenosis intervention but also morbidity of acute ischemic stroke events during CABG.
