RESUMO
OBJECTIVE: The study objective was to describe the course and outcomes of children under 18 years of age, with left-to-right shunts and pulmonary arterial hypertension undergoing 1 of 2 management approaches: pulmonary arterial hypertension treatment before left-to-right shunt repair (Treat First) and left-to-right shunt repair first with or without subsequent pulmonary arterial hypertension treatment (Repair First). METHODS: We performed a retrospective single-center study, conducted from September 2015 to September 2021, of children with left-to-right shunts and pulmonary arterial hypertension (defined as indexed pulmonary vascular resistance ≥ 4 Wood units [WU]∗m2) but without Eisenmenger physiology. Patient characteristics, longitudinal hemodynamics data, pulmonary arterial hypertension management, left-to-right shunt repair, and outcomes were reviewed. RESULTS: Of 768 patients evaluated for left-to-right shunt closure, 51 (6.8%) had left-to-right shunts associated with pulmonary arterial hypertension (median age 1.1 [0.37-5] years, median indexed pulmonary vascular resistance 6 [5.2-8.7] WU∗m2). In the "Treat First" group (n = 33, 65%), 27 patients (82%) underwent left-to-right shunt closure and 6 patients (18%) did not respond to pulmonary arterial hypertension therapy and did not undergo left-to-right shunt closure. In the "Repair First" group (n = 18, 35%), 12 patients (67%) received pulmonary arterial hypertension therapy and 6 patients (33%) did not. Mortality rates were 6% in the "Treat First" group and 11% in "Repair First" group with follow-ups of 3.4 and 2.5 years, respectively. After left-to-right shunt closure, there was no significant change in indexed pulmonary vascular resistance over a median follow-up of 2 years after surgery (P = .77). CONCLUSIONS: In children with left-to-right shunts and associated pulmonary arterial hypertension, treatment with pulmonary arterial hypertension-targeted therapy before defect repair does not appear to endanger the subjects and may have some benefit. The response to pulmonary arterial hypertension-targeted therapy before shunt closure persists 2 to 3 years postclosure, providing valuable insights into the long-term management of these patients.
RESUMO
BACKGROUND: Despite guidelines recommending narrow-spectrum perioperative antibiotics (NSPA) as prophylaxis for most children undergoing congenital heart disease (CHD) surgery, broad-spectrum perioperative antibiotics (BSPA) are variably used, and their impact on postoperative outcomes is poorly understood. METHODS: We used administrative data from U.S. hospitals participating in the Vizient Clinical Data Base. Admissions from 2011 to 2018 containing a qualifying CHD surgery in children 0-17 years old were evaluated for exposure to BSPA versus NSPA. Propensity score-adjusted models were used to compare postoperative length of hospital stay (PLOS) by exposure group, while adjusting for confounders. Secondary outcomes included subsequent antimicrobial treatment and in-hospital mortality. RESULTS: Among 18 088 eligible encounters from 24 U.S. hospitals, BSPA were given in 21.4% of CHD surgeries, with mean BSPA use varying from 1.7% to 96.1% between centers. PLOS was longer for BSPA-exposed cases (adjusted hazard ratio 0.79; 95% confidence interval [CI]: 0.71-0.89, P < .0001). BSPA was associated with higher adjusted odds of subsequent antimicrobial treatment (odds ratio [OR] 1.24; 95% CI: 1.06-1.48), and there was no significant difference in adjusted mortality between exposure groups (OR 2.06; 95% CI: 1.0-4.31; P = .05). Analyses of subgroups with the most BSPA exposure, including high-complexity procedures and delayed sternal closure, also did not find (but could not exclude) a measurable benefit from BSPA on PLOS. CONCLUSIONS: BSPA use was common in high-risk populations, and varied substantially between centers. Standardizing perioperative antibiotic practices between centers may reduce unnecessary broad-spectrum antibiotic exposure and improve clinical outcomes.

A 24-year-old woman was referred to pulmonologist with worsening breathlessness and wheeze. During childhood, she was diagnosed with asthma and subsequent exacerbations were treated with bronchodilators for many years. The chest X-ray and a spirometry testing raised a doubt of extrinsic tracheal compression and a subsequent enhanced chest CT (computerized tomogram) scan confirmed a right-sided aortic arch and a vascular ring anomaly compressing the trachea. Standard surgical division of ligamentum arteriosum was able to relieve the trachea and so the symptoms.

Intrathoracic teratomas almost always occur in the mediastinum, but occasionally, they may be found in the lung as intrapulmonary teratomas. Intrapulmonary teratomas have histologic findings that are similar to those of teratoma from other sites. Two successive patients with intrapulmonary teratomas presented to us in a variable manner. The clinical and radiologic features and the histopathologic findings are presented, and the relevant literature is discussed.
