[Risk factors for the formation of congenital hyperplasia of blood vessels (infantile hemangioma)].

OBJECTIVE: The aim the study. To identify correlations between the development of blood vessel hyperplasia (GCS) and risk factors in pregnant women. To identify correlations between the development of blood vessel hyperplasia (GCS) and risk factors in pregnant women.

MATERIALS AND METHODS: A selective retrospective analysis of 173 case histories and outpatient records of patients of the Clinic of Pediatric Maxillofacial Surgery and Dentistry of the Central Research Institute of Dentistry and Maxillofacial Surgery for 2011-2021 was carried out. The obstetric history of the mother, chronic diseases of mothers during pregnancy and bad habits were studied. The interrelation of the influencing unfavorable factor on the isolation, prevalence and vastness of foci of infantile hemangioma was determined.

RESULTS AND DISCUSSION: There was no statistically significant relationship between the harmful habits of the mother and the number of lesions, as well as the isolation of the lesion of the mandibular-facial region (CHLO) and the prevalence of the process in the child. It was found that the prevalence of the process, the isolation of the lesion and the number of foci of CHLO did not have a reliable relationship with the complicated course of pregnancy in the mother. A reliable relationship was revealed between the number of lesions in the CHLO and chronic hypoxia, between the number of defects of the cardiovascular system and the prevalence of the process. But there was no reliable relationship between the number of CCC lesions and the number of lesions. 24 patients out of 173 were premature. In these patients, a statistical severity to the occurrence of GCS was revealed. There was no reliable relationship between the genetic predisposition on the line of both parents and the prevalence of the process, with the isolation of the lesion of CHLO and with the number of foci of CHLO lesions.

CONCLUSION: Prematurity, chronic hypoxia, multiple malformations of the fetal cardiovascular system are risk factors for the development of vascular hyperplasia in children.
