SURGICAL TREATMENT OF PATIENTS WITH EXTRAORGANIC TUMORS OF THE PELVIC LOCALIZATION WITH INVASION OF THE ILIAC VESSELS

The aim of our study was to determine the indications for expanding the scope of operations in patients with pelvic extraorgan local formations. Materials and methods. The results of surgical treatment of 7 patients with nonorgan tumors of the pelvic localization, who underwent resection on the main vessels in connection with their involvement in the tumor process, are presented. Results and discussion. A total of 7 interventions were performed on the iliac arteries — 2 resections with an end-to-end anastomosis and 5 prostheses (one case — the aorta resection with reconstruction with a bifurcation prosthesis). Patients with pelvic extraorgan tumors are a special cohort of patients, due to the presence of several organs in a narrow space, which inevitably causes them to fit snugly to the tumor. Locally advanced tumor process in extraorganic tumors involving the main vessels of the pelvis and adjacent organs is not a reason to refuse surgery, and despite the complications, repeated recurrences and previous operations, are well tolerated by patients. This is especially important due to the lack of a real alternative to surgical treatment of this group of patients. Conclusions. Surgical intervention in the treatment of pelvic inorganic tumors involving the main vessels is the only radical method of treatment. Invasion of the main arterial and venous vessels is not a contraindication to surgery in patients with pelvic tumors. Combined angioplastic interventions allow to achieve a long without recurrent period even after cytoreductive operations.
