PREDICTING THE EFFECTIVENESS OF TRANSCATHETERARTERIAL EMBOLIZATION OF LIVER HEMANGIOMAS

Objective: optimization results of treatment of patients who have liver hemangiomas by predicting the results of transcatheter arterial embolization. Materials and methods. Retrospective analysis of 37 cases of patients who has liver hemangiomas who underwent transcatheter arterial embolization at the hospital surgery clinic of the Kirov Military Medical Academy in the period from 2011 to 2019 was conducted. Single hemangiomas were detected from 23 cases, multiple hemangiomas from 14 cases. Growth of hemangioma was observed at 26 patients, and stable size was observed at 11 patients. The size of liver hemangiomas in patients ranged from 35 to 159 mm (on average 85.4 ± 31.5 mm), depending on the size of the beingness, all cases were divided into 3 groups: 1) down 60 mm (n = 12); 2) from 61 to 90 mm (n = 13);3) from 91 mm or more (n = 12). Results of the study: in the groups with single and multiple liver hemangiomas, transcatheter arterial embolization efficiency indicators were similar: 50 and 52.2%, respectively (p = 0.85). In the group with dynamic growth of liver hemangiomas, the effectiveness was 38.5%, in the group without dynamic growth - 81.8% (p < 0.05). In the group with the size of liver hemangiomas up to 60 mm, the efficiency of transcatheter arterial embolization was 91.7%, in the group with the size from 61 to 90 mm - 46.2%, in the group with the size of 91 mm or more - 8.3% (p < 0.05). Conclusion. The effectiveness of transcatheter arterial embolization liver hemangiomas is negatively affected by the size of the hemangioma more than 60 mm and its dynamic growth. The correlation between the number of liver hemangiomas and the effectiveness of transcatheter arterial embolization was not revealed (5 figs, bibliog r aphy: 15 refs).
