Background. Inorganic retroperitoneal tumors (IRT) are neoplasms that have no organ affiliation and develop from soft tissues located in the retroperitoneal space (adipose, connective, vascular, nervous), as well as from embryonic elements. IRT account for 0.03 to 1.0 % of all human neoplasms. Malignant IRT account for up to 70 %, while benign – up to 30 %. Operations for retroperitoneal tumors are accompanied by a high risk of intra- and postoperative complications [3]. With large retroperitoneal tumors the main difficulties are compression syndrome of the abdominal cavity, the syndrome of compression of the inferior vena cava, difficulties of mobilizing of the tumor due to a small surgical maneuver and large size of the tumor.
Purpose. Introducing the clinical course peculiarities of giant tumors of the retroperitoneal space and possible intra- and perioperative complications to the medical community.
Materials and methods. Clinical case of patient A., 44 years old, who was treated in the oncology surgery department of SO «Grigoriev Institute for Medical Radiology and Oncology of the National Academy of Medical Sciences of Ukraine».
Results. Removal of the tumor of the retroperitoneal space with technical difficulties was performed. In the postoperative period after surgery, bleeding from a varicose vein of the abdominal wall. Surgical treatment was performed: relaparotomy, hemostasis. The term of supervision is 3 years, there is no data for recurrence.
Conclusions. If IRT is additionally accompanied by a syndrome of inferior vena cava compression, it is necessary to carry out careful hemostasis intraoperatively, and to conduct active supervision in the nearest postoperative period for control of possible bleeding after filling of earlier «empty» vessels.
