Background. Paragangliomas are rare neuroendocrine tumors that often located paravertebrally in the retroperitoneal space and near major abdominal blood vessels. Surgical resection is the primary treatment for paragangliomas. A close adjacency between a tumor and the main vessels requires a combined treatment approach: a surgical resection of a tumor along with a portion of the vascular trunk, ensuring that the removed tissue is within the healthy surrounding areas. Separation of the tumor from the vessel may potentially leave a microscopic margin of tumor cells on the vessel wall (R1 resection) and usually results in damage to the vessel and significant blood loss. Case presentation. We present here the case of surgical treatment of paraganglioma of the organ of Zuckerkandl in a 52-year-old female patient. A close adjacency of the tumor to the aortic bifurcation required tumor resection involving the aortic bifurcation and subsequent reconstruction of the main blood flow using a Polytetrafluoroethylene (PtFe) bifurcation aorto-common iliac alloprosthetic graft (PtFe conduit). The postoperative period was uneventful. The patient is stable and is currently under follow-up care. Conclusion. This case report demonstrates the feasibility of performing radical surgery in patients with retroperitoneal paragangliomas closely adjacent to the major vessels.
