[Surgeries on major vessels in removal of different tumors]

Experience in diagnosis and surgical treatment of 49 patients with tumors of different localization close to their major with main vessels is analyzed. Two variants of tumor - vessel interrelation were seen, patients with iatrogenic vascular lesions were included into a separate group. In 9 patients (group 1) only extravasal compression by the tumor was seen. Most of these tumors were benign. In 15 patients (group 2) reconstructive vascular surgeries were performed because of close interrelation with the tumor or tumor spread into the vessel. Most of these tumors were malignant. Iatrogenic lesions of arteries during surgeries were in 25 patients (group 3). It is demonstrated that duplex sonography permits to diagnose affection of vessels by tumors without invasive procedures. All the patients underwent vascular reconstruction simultaneously with tumor removing. Sceletization of vessels with their decompression was the surgery of choice in benign tumors. In malignant tumors it is recommended to remove the tumor with affected segment of vessel and repair of blood flow. Ligation of vessel may be justified in some cases.
