The patient, a 20-day-old male, was admitted due to respiratory distress that had persisted for 20 days after birth. The main clinical manifestations included gradually worsening respiratory distress and edema. The patient received treatment including mechanical ventilation and diuretics. Echocardiography indicated cardiomegaly, pulmonary hypertension, and heart failure. A comprehensive systemic examination revealed a significant blowing vascular murmur upon auscultation over the anterior fontanelle and bilateral temporal regions. Further imaging studies including cranial magnetic resonance imaging, magnetic resonance angiography, and magnetic resonance venography showed marked dilation of the superior sagittal sinus, transverse sinus, and sigmoid sinus, leading to a definitive diagnosis of dural arteriovenous fistula. After a multidisciplinary consultation, the patient underwent cerebral angiography and partial embolization of the left parietal arteriovenous fistula. Postoperatively, the patient was treated with positive inotropes, diuretics, and fluid restriction. Ultimately, the patient was weaned off the ventilator and discharged in improved condition. This article reports a case of neonatal dural arteriovenous fistula presenting with respiratory distress and discusses the multidisciplinary approach to managing this condition, which aids in early disease recognition and guides clinical decision-making.

Congenital heart disease is the most common birth defect, affecting 1%–1.2% of live born infants. Pulmonary atresia with intact ventricular septum (PA-IVS) accounts for <1% of all total heart defects. The cause of PA-IVS has been unclear. Thus, experience for prenatal diagnosis of PA-IVS is limited in any single institution. This is the case of a 28-year-old gravida 1 para 0 who came in at 34 + 5 weeks of gestational age. Fetal two-dimensional (2D) echocardiography revealed Type II PA-IVS, higher risk for univentricular circulation postnatally. She gave birth at term by vaginal delivery, with confirmed findings through a 2D echocardiography. Prenatal diagnosis of PA-IVS allows options for the termination of pregnancy, fetal cardiac interventional therapy, early postnatal initiation of prostaglandin E1, and planned early neonatal interventional surgeries for palliation and repair. Early assessment of fetal cardiac features is useful for a better outcome.

Vascular malformations are aberrant proliferations of blood vessels that may present at birth or develop subsequently. Capillary malformations (CMs) represent the most common category of vascular malformations. They generally present as localized discoloration, including port-wine stains (PWSs) and telangiectasia. Certain PWSs, especially those affecting the V2 dermatome, may give rise to pyogenic granulomas or other epithelial or mesenchymal hamartomas.

We present a case of a 46-year-old male with a 5-year history of a solitary, progressively enlarging firm papule on an erythematous patch or “birthmark” on his left cheek. Despite infrequent manipulation, there were no reports of bleeding or any associated symptoms, including pain, pruritus, and thrills. The patient sought consultation for cosmetic reasons and wanted to have the lesion removed. Hence, an excision biopsy revealed a well-defined proliferation of mature thick and thin-walled vessels, lined by a single layer of endothelial cells, surrounded by dysmorphic and irregularly arranged vessels consistent with arteriovenous malformation with capillary malformation.

Capillary malformation (CM) is the most common form of vascular malformation. Fifty percent of port-wine stains (PWSs), which is the most common (CM) in children, are in the face area innervated by the second branch of the trigeminal nerve. Arteriovenous malformations manifest in the advanced stages of PWSs and, alongside pyogenic granuloma, represent underreported histological changes inside mature PWSs, especially in the face area innervated by the second branch of the trigeminal nerve (V2).

OBJECTIVES: Digital subtraction angiography (DSA) is the current gold standard for diagnosing spinal dural arteriovenous fistulas (SDAVF). However, DSA is invasive and associated with risks such as ionizing radiation and iodine contrast allergy. Contrast-enhanced magnetic resonance angiography (CE-MRA) with high temporal/high spatial resolution allows dynamic multiphase contrast-enhanced imaging with excellent detail. This study aims to evaluate the diagnostic value of spinal CE-MRA with high temporal/high spatial resolution for SDAVF. METHODS: Clinical data were retrospectively collected from patients who underwent both conventional spinal MRI and high temporal/high spatial resolution CE-MRA at Xiangya Hospital between January 1, 2021, and January 1, 2024, and who subsequently underwent DSA or surgery within 90 days. Two experienced radiologists independently reviewed all conventional MRI and CE-MRA images. The sensitivity and specificity of conventional MRI and CE-MRA for diagnosing SDAVF were calculated against the gold standard DSA findings. Kappa statistics were used to evaluate the consistency of MRI and CE-MRA compared to DSA. The diagnostic value was further assessed by calculating the area under curve (AUC) of the receiver operating characteristic (ROC). RESULTS: A total of 60 patients were included, of whom 47 were diagnosed with SDAVF and 13 were not. Conventional MRI had 3 false negatives and 1 false positive; CE-MRA had 2 false positives and 0 false negative. The sensitivity and specificity of conventional MRI were 93.62% and 92.31%, respectively. CE-MRA demonstrated 100% sensitivity and 84.62% specificity. The main cause of false positives was the misidentification of posterior spinal arteries as feeding arteries. CE-MRA clearly displayed most feeding arteries, and the accuracy of fistula localization was 74.47% (35/47). Kappa values for conventional MRI and CE-MRA were 0.814 and 0.896, respectively (both P<0.001), indicating good agreement, with CE-MRA outperforming conventional MRI. The AUCs for diagnosing SDAVF were 0.930 for conventional MRI and 0.923 for CE-MRA (both P<0.05). CONCLUSIONS Spinal CE-MRA with high temporal/high spatial resolution is a reliable, non-invasive imaging technique with high sensitivity for diagnosing SDAVF. It can clearly visualize feeding arteries and provides valuable preoperative diagnostic and localization information to support DSA or surgical planning.

Vascular malformations are due to abnormal development of blood and/or lymphatic vessels during embryonic life without endothelial cell proliferation. Most of the previous treatments were symptomatic methods as surgery and sclerotherapy because the pathogenic mechanism was not clearly understood. With advances in molecular biology, the pathogenesis of vascular malformations is thought to be related to inherited and/or somatic mutations that eventually activate the PI3K/ATK/mTOR, Ras/Raf/MEK/ERK pathways. Also, related studies have promoted the use of targeted inhibitors. This article provides a review of current causative genes and targeted drugs for pediatric vascular malformations, aiming to provide a basis for promoting accurate molecular diagnosis and precision targeted therapy for these diseases.

OBJECTIVES: To evaluate the clinical effectiveness of integrated management during the perinatal period for fetuses diagnosed with total anomalous pulmonary venous connection (TAPVC) by prenatal echocardiography. METHODS: Clinical data of 64 cases of TAPVC fetuses diagnosed by prenatal echocardiography and managed with integrated perinatal care in Qingdao Women and Children's Hospital from January 2017 to December 2021 were retrospectively analyzed. Integrated perinatal care included multidisciplinary collaboration among obstetrics, fetal medicine, ultrasound, pediatric cardiology, pediatric anesthesia, and neonatology. RESULTS: Among the 64 TAPVC fetuses, there were 29 cases of supracardiac type, 27 cases of intracardiac type, 2 cases of infracardiac type, and 6 cases of mixed type. Chromosomal analysis was performed in 42 cases, and no obvious abnormalities were found. Among the 64 TAPVC fetuses, 37 were induced labor, and 27 were followed up until term birth. Among the 27 TAPVC cases, 2 cases accepted palliative care, 2 cases were referred to another hospital for treatment and lost to follow-up, while the remaining 23 cases underwent primary repair surgery. One case died within 6 months after the operation due to low cardiac output syndrome, while the other 22 cases were followed up for (2.1±0.3) years with good outcomes (2 cases underwent a second surgery within 1 year after the first operation due to anastomotic stenosis or pulmonary vein stenosis). CONCLUSIONS TAPVC fetuses can achieve good outcomes with integrated management during the perinatal period.

Objectives: To analyze the reasons of missed diagnosis or misdiagnosis on anomalous origin of left coronary artery from pulmonary artery (ALCAPA) by echocardiography. Methods: This is a retrospective study. Patients with ALCAPA who underwent surgical treatment in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from August 2008 to December 2021 were included. According to the results of preoperative echocardiography and surgical diagnosis, the patients were divided into confirmed group or missed diagnosis/misdiagnosis group. The results of preoperative echocardiography were collected, and the specific echocardiographic signs were analyzed. According to the experience of the doctors, the echocardiographic signs were divided into four types, namely clear displayed, vague/doubtful displayed, no display and no notice, and the display rate of each sign was calculated (display rate=number of clearly displayed cases/total number of cases×100%). By referring the surgical data, we analyzed and recorded the pathological anatomy and pathophysiological characteristics of the patients, and the rate of missed diagnosis/misdiagnosis of echocardiography in patients with different characteristics was compared. Results: A total of 21 patients were enrolled, including 11 males, aged 1.8 (0.8, 12.3) years (range 1 month to 47 years). Except for one patient with anomalous origin of left anterior descending artery, the others were all originated from the main left coronary artery (LCA). There were 13 cases of ALCAPA in infant and children, and 8 cases of adult ALCAPA. There were 15 cases in the confirmed group (diagnostic accuracy was 71.4% (15/21)), and 6 cases in the missed diagnosis/misdiagnosis group (three cases were misdiagnosed as primary endocardial fibroelastosis, two cases were misdiagnosed as coronary-pulmonary artery fistula; and one case was missed diagnosis). The working years of the physicians in the confirmed group were longer than those in the missed diagnosis/misdiagnosed group ((12.8±5.6) years vs. (8.3±4.7) years, P=0.045). In infants with ALCAPA, the detection rate of LCA-pulmonary shunt (8/10 vs. 0, P=0.035) and coronary collateral circulation (7/10 vs. 0, P=0.042) in confirmed group was higher than that in missed diagnosis/misdiagnosed group. In adult ALCAPA patients, the detection rate of LCA-pulmonary artery shunt was higher in confirmed group than that in missed diagnosis/misdiagnosed group (4/5 vs. 0, P=0.021). The missed diagnosis/misdiagnosis rate of adult type was higher than that of infant type (3/8 vs. 3/13, P=0.410). The rate of missed diagnosis/misdiagnosis was higher in patients with abnormal origin of branches than that of abnormal origin of main trunk (1/1 vs. 5/21, P=0.028). The rate of missed diagnosis/misdiagnosis in patients with LCA running between the main and pulmonary arteries was higher than that distant from the main pulmonary artery septum (4/7 vs. 2/14, P=0.064). The rate of missed diagnosis/misdiagnosis in patients with severe pulmonary hypertension was higher than that in patients without severe pulmonary hypertension (2/3 vs. 4/18, P=0.184). The reasons with an echocardiography missed diagnosis/misdiagnosis rate of≥50% included that (1) the proximal segment of LCA ran between the main and pulmonary arteries; (2) abnormal opening of LCA at the right posterior part of the pulmonary artery; (3) abnormal origin of LCA branches; (4) complicated with severe pulmonary hypertension. Conclusions: Echocardiography physicians' knowledge of ALCAPA and diagnostic vigilance are critical to the accuracy of diagnosis. Attention should be paid to the pediatric cases with no obvious precipitating factors of left ventricular enlargement, regardless of whether the left ventricular function is normal or not, the origin of coronary artery should be routinely explored.
