Prevention and Treatment of Complications of Endovascular Methods in Patients With Malignant Liver Tumors

Overview

In the structure of malignant liver lesions, two main groups are distinguished - primary liver cancer and metastatic liver damage. The five-year survival rate of patients with malignant liver tumors does not exceed 6%. The main and radical method of treatment today is liver resection. However, surgical treatment is possible only in 10-25% of patients. At the same time, recurrence of malignant tumors is observed in 60-80% of cases within five years after surgery, and the number of candidates for repeated liver resection does not exceed 10%. The high toxicity of systemic chemotherapy limits its use in this group of patients. In this connection, minimally invasive and at the same time effective methods of local treatment of malignant liver tumors have been introduced into clinical practice. These methods include: hepatic artery chemoinfusion, chemoembolization and oil chemoembolization. Currently, a large world experience has already been accumulated in the application of the above methods of treatment. However, any, even minimally invasive, surgical manipulation can be associated with the development of complications of varying severity. If complications arise, there is a risk of interruption of palliative care, which entails a significant reduction in life expectancy. According to domestic and foreign literature, the occurrence of complications after intra-arterial chemoembolization occurs in 0.4-10% of patients, and after intra-arterial chemoinfusion - in 5-30% of patients. In the overwhelming majority of scientific works, the description of the complications that have arisen is reduced to listing the latter. Currently, in the Russian and foreign scientific literature there is no systematization of complications, there is no single clinical classification, algorithms for the prevention and treatment of complications arising after local intravascular methods of treatment of patients with malignant liver tumors. The study and systematization of complications arising after intra-arterial chemoembolization and chemoinfusion of the hepatic artery in patients with malignant liver tumors will make it possible to create prevention and treatment algorithms. Thus, it will help prevent interruption of palliative care and increase the life expectancy of this cohort of patients.
