ABSTRACT

La malformación congénita de la vía aérea pulmonar (MVAP), antes llamada malformación adenomatoidea quística pulmonar, es una rara anormalidad del desarrollo de las vías respiratorias terminales. Las lesiones son de distribución y tamaños variables, usualmente unilaterales. El diagnóstico puede realizarse desde el período prenatal mediante ecografía gestacional, encontrándose, en ocasiones, graves repercusiones fetales. En los recién nacidos la enfermedad puede manifestarse con dificultad respiratoria aguda. En niños y adultos puede diagnosticarse ante infecciones pulmonares recurrentes u otras complicaciones. En pacientes sintomáticos está indicado el tratamiento quirúrgico para prevenir infecciones y la transformación neoplásica; sin embargo, sigue siendo controversial el tratamiento profiláctico frente al tratamiento expectante en pacientes asintomáticos. Se presenta el caso clínico de una lactante de 2 meses, que en el curso de una bronquiolitis se realizó una radiografía de tórax que evidenció una imagen radiolúcida del lóbulo medio. La tomografía computada visualizó gran imagen quística en pulmón derecho, que podría corresponder a una MVAP. Se decidió tratamiento quirúrgico coordinado. Se realizó una segmentectomía, confirmándose con anatomía patológica una MVAP tipo IV. Evolucionó favorablemente.


Congenital pulmonary airway malformation (CPAM), formerly called pulmonary cystic adenomatoid malformation, is a rare developmental abnormality of the terminal airways. Lesions are of variable size and distribution, usually unilateral. The diagnosis can be made from the prenatal period by means of gestational ultrasound, occasionally causing serious fetal repercussions. In newborns, the disease may manifest itself through acute respiratory distress. In children and adults it can be diagnosed through recurrent lung infections or other complications. In symptomatic patients, surgical treatment is indicated to prevent infections and neoplastic transformation. However, prophylactic versus expectant management in asymptomatic patients remains controversial. We present the clinical case of a 2-month-old infant who, during the course of bronchiolitis underwent a chest X-ray that revealed a radiolucent image of the middle lobe. The computed tomography scan showed a large cystic image in the right lung, which could be linked to an CPAM. The surgical treatment was carried out and the segmentectomy confirmed a pathological type IV CPAM. The patient evolved favorably.


A malformação congênita das vias aéreas pulmonares (MVAP), anteriormente chamada de malformação adenomatoide cística pulmonar, é uma anormalidade rara do desenvolvimento das vias aéreas terminais. As lesões são de tamanho e distribuição variáveis, geralmente unilaterais. O diagnóstico pode ser feito desde o pré-natal por meio da ultrassonografia gestacional, podendo encontrar repercussões fetais graves. Em recém-nascidos, a doença pode se manifestar com dificuldade respiratória aguda. Em crianças e adultos, pode ser diagnosticada com infecções pulmonares recorrentes ou outras complicações. Em pacientes sintomáticos, o tratamento cirúrgico é indicado para prevenir infecções e transformações neoplásicas; no entanto, o tratamento profilático versus expectante em pacientes assintomáticos permanece controverso. Apresentamos o caso clínico de uma criança de 2 meses que foi submetida a radiografia de tórax durante bronquiolite, que revelou imagem radiotransparente do lobo médio. A tomografia computadorizada mostrou grande imagem cística em pulmão direito, que poderia corresponder a uma MVAP. O tratamento cirúrgico foi realizado e a segmentectomia confirmou um tipo IV de MVAP com patologia. A criança evoluiu favoravelmente.

ABSTRACT

Abstract Objective To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM). Methods We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis. Results The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. Themedian gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case). Conclusion A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.

ABSTRACT

RESUMEN OBJETIVO: el propósito es describir el efecto de los corticoides prenatales en la malformación congénita de la vía aérea pulmonar (MCVAP) mediante la evaluación secuencial del CVR y mostrar la experiencia en nuestro centro de terapia fetal. MATERIALES Y MÉTODOS: serie de casos en la cual se incluyeron ocho pacientes del Hospital de San José; con diagnóstico de MCVAP; se evaluó edad gestacional, el CVR (longitud x largo x ancho, en cms de la masa) x 0.523/circunferencia cefálica) como factor pronóstico, la desviación mediastínica, la presencia de hidrops, el tipo de MCVAP y la localización. Se aplicó betametasona a dosis de inducción de madurez pulmonar fetal. Se realizó la medición del CVR pre y pos tratamiento. Los datos obtenidos fueron analizados mediante el software estadístico SPSS (Versión 11.0 SPSS Inc. Chicago, IL). Se utilizaron la prueba Wilcoxon y el índice de correlación de Spearman según el caso. Un valor de p<0.05 se consideró significativo. RESULTADOS: ocho pacientes fueron incluidas. La mediana de la edad gestacional fue 30.5 semanas. Cuatro casos fueron tipo I, dos tipo II y dos tipo tres. Cuatro casos presentaron desviación mediastinal. Cinco casos fueron derechos y uno bilateral. Ningún caso presentó hidrops. El CVR pre tratamiento fue 0,93(RIQ:0,17-2,1) y pos tratamiento 0,55(RIQ:0,07-1,39). Se encontró una disminución del CVR pos tratamiento en todos los casos (p 0.0117) e índice de correlación de Spearman 0.9524 CONCLUSIÓN: Después de la aplicación de corticoides encontramos una disminución del CVR en todos los casos descritos. El uso de corticoides podría ser parte de la terapia prenatal con miras a mejorar el pronóstico.


ABSTRACT OBJECTIVE: The purpose of this study is to describe the effect of prenatal corticosteroids in the CPAM by sequential evaluation of the CVR, and to show the experience in our fetal therapy center. MATERIALS AND METHODS: Series of cases in which eight patients from the Hospital of San José were included; with diagnosis of CPAM; gestational age was evaluated, CVR (CVR = length x length x width cm, mass) x 0.523 / head circumference) as a prognostic factor, mediastinal shift, hydrops, type of CPAM, location. Betamethasone was applied to fetal lung maturation dose. In all patients underwent CVR measurement pre and post treatment. The data were analyzed using SPSS statistical software (Version 11.0 SPSS Inc. Chicago, IL). The Wilcoxon test and the Spearman correlation index were used according to the case. A value of p <0.05 was considered significant. RESULTS: eight patients were included. The median of gestational age was 30.5 weeks. Four cases were type I, two type II and two type three. Four cases were mediastinal shift. Five cases were rights and one bilateral. No case presented hydrops. The pretreatment CVR was 0,93(RIQ: 0,17-2,1) and post-treatment 0,55(RIQ: 0,07-1,39). We found a decrease in CVR after treatment in all cases (p 0.0117) and Spearman correlation index 0.9524 CONCLUSION: After application of corticosteroids are a reduction in CVR in all the cases described. The use of corticosteroids may be part of prenatal therapy to improve prognosis.

ABSTRACT

Objective: To describe 16 patients treated for a congenital pulmonary anomaly named congenital pulmonary airway malformation (CPAM) or congenital cystic adenomatoid malformation (CCAM) in Roberto del Río children S Hospital. Methods: We retrospectively analyzed the medical records of patienes who had had surgery for CPAM/CCAM from January 2000 to July 2014. Results: We found 16 cases, 9 of them were males. Nine had surgery within the first year of life (5 of them within 3 weeks of life). According to Stocker 's classification CPAM/CCAM was type 1 in 9 patients, and type 2 in 7. Diagnosis was based on antenatal ultrasonography s (n = 10), persistent abnormalities in Chest X-Ray (n = 4), recurrent pneumonia (n = 1) and incidental radiological findings (n = 1). Computed Tomography (CT) was performed in 13 patients, CT angiography in 2 and only chest x-ray in one. The lesions were located in right upper lobe (3), right middle lobe (2), right lower lobe (4), left upper lobe (4) and left lower lobe (3). One patient had pectus excavatum and another one had ventricuar septal defect. They all had open thoracotomy with lobectomy of the affected area. Postoperatively was uneventful except for transient lobar atelectasis in 2 patients. There was no mortality. Conclusions: We emphasize the early diagnosis and good outcome of our patients treated which this disease. Our findings are consistent with those that has been reported in the literature.
