Successful surgical treatment of a patient with locally advanced adrenocortical cancer with prosthetic replacement of the IVC section with cryopreserved allograft using a venovenous bypass shunt

Adrenocortical carcinoma (ACC) is a rare malignant tumor of the adrenal cortex, usually characterized by late detection, aggressive clinical course and unfavorable treatment prognosis. In some cases, patients with ACC have tumor invasion into the IVC, which requires vascular resection of varying extent (longitudinal or circular) with or without subsequent reconstruction. In this article, we report a case of a tumor of the right adrenal gland with tumor thrombosis of the IVC. The patient underwent radical nephradrenalectomy on the right with resection of the inferior vena cava and simultaneous vena cava plastic surgery with cryopreserved allograft under conditions of bypass cava-caval shunting. IVC replacement with cryopreserved allograft using parallel circulation is a rare surgical intervention requiring the work of a multidisciplinary team, with a limited number of cases that can be described in the literature, the authors of this article present this case for consideration.
