CONGENITAL BRONCHIAL MALFORMATIONS ASSOCIATED WITH CONGENITAL HEART DEFECTS

Аннотация

The association of congenital bronchial anomalies with congenital heart defects is linked to disruptions in embryonic development, which necessitates careful monitoring and early intervention for patients suspected of having these anomalies. Pathophysiological processes can significantly vary depending on the type of anomaly, its severity, and the involvement of other organs. Therefore, it is crucial to conduct thorough examinations of patients with suspected congenital bronchial anomalies to identify any accompanying disorders early and prevent life-threatening risks.

Introduction. The association between congenital bronchial anomalies and congenital heart defects originates from disruptions in embryonic development. These anomalies are not only anatomically interconnected but also share common pathophysiological mechanisms, clinical manifestations, and treatment strategies. The coexistence of bronchial anomalies and congenital heart defects often leads to significant impairments in both the respiratory and circulatory systems, complicating disease progression and management. Since the formation of the respiratory and cardiovascular systems is closely linked during embryogenesis, even minor developmental disturbances can result in various pathological conditions. Such anomalies frequently coexist with atrial septal defect, patent ductus arteriosus, left ventricular hypoplasia, and total pulmonary venous anomaly. These conditions contribute to pulmonary hypertension and respiratory insufficiency, manifesting as breathing difficulties,hypoxia, and heart failure inaffected patients. Therefore, early detection of congenital bronchial anomalies and their associated heart defects, along with comprehensive diagnostic and targeted therapeutic approaches, is crucial. 98,7:ROTCAFTCAPMI.SECNEICSLACIDEM ,5202 ,hcraM,5emuloV gro.srehsilbupcimedaca.www Studying these pathologies not only enhances diagnostic and treatment capabilities but also plays avital rolein preventingsevere complications andimproving patient outcomes. Relevance and necessity of the study. The relevance and necessity of this topic align with the findings in the scientific literature (G.I. Kolpinskiy, S.N. Burdin, A.S. Shkaraburov, 2016; I.I. Zakirov et al., 2014), which indicate that a significant proportion of children born with congenital bronchial anomalies do not have other congenital defects. However, research has revealed that in cases where congenital bronchial anomalies are present, congenital heart defects are frequently identified as well. The consistent co-occurrence of congenital heart defects in all observed cases highlights thesignificance ofthis topic. Studies conducted in Uzbekistan confirm that congenital bronchial anomalies are often associated with the following congenital heart defects: atrial septal defect, patent ductus arteriosus, left ventricular hypoplasia, total anomalous pulmonary venous return, pulmonary artery hypertension, pulmonary veins draining into the right atrium, and hypertrophy of the right atrium and right ventricle. The correlation between specific types of congenital bronchial anomalies and congenital heart defects has been established. Congenital lung diseases are rare, but their clinical presentation and progression vary significantly, ranging from large masses to minor asymptomatic lesions. Some cases require urgent surgical intervention due to their severity. The consequences of congenital lung anomalies can becritical, making theirtimelydiagnosis and treatment highly relevant. Understanding lung development and anatomy serves as a fundamental basis for assessing these anomalies, helping to comprehend the pathophysiology of each condition and analyze various diagnostic approaches. Research in this area holds particular scientific and practical significance, contributingtotheadvancement ofdiagnosticand therapeutic strategies. Objective. Quantitative indicators were processed using descriptive and variation statistical methods. The obtained micropreparations were analyzed at 200x magnification, and cellular structures within the field of view were mathematically calculated using the NanoZoomer (REF C13140-21, S/N000198, HAMAMATSU PHOTONICS, 431-3196, JAPAN). Morphometric parameters were measured in micrometers (µm) using the Hamamatsu (QuPath-0.4.0, NanoZoomer Digital Pathology Image) software, and statistical analysis was performed todeterminethe averagevalues and overall statistical significance.
