Abstract:
Objective Characteristics of the retroperitoneal tumor blood supply arteries were analyzed to evaluate the safety and effectiveness of preoperative interventional embolization for benign and malignant retroperitoneal tumors.
Methods A total of 241 cases were divided into benign retroperitoneal tumor group and malignant retroperitoneal tumor group. Each group was divided into groups A, B, and C according to the long diameter of the tumor tissue. Group A > 10.0 cm, 5.0 cm < group B ≤10.0 cm, and group C ≤5.0 cm. Tumor volume, intraoperative blood loss, intraoperative blood transfusion, operation time, and hospitalization days were compared with 70 cases of preoperative interventional embolization of retroperitoneal tumor blood supply artery.
Results No significant difference in the operation time, intraoperative bleeding, and postoperative hospital stay was found in groups A, B, and C of the benign tumor group (P > 0.05). Significant differences in intraoperative bleeding and intraoperative blood transfusion were found between groups A and B (P < 0.05). Main arteries of the abdominal retroperitoneal tumor are the lumbar, internal iliac, and adrenal arteries. The main artery of pelvic retroperitoneal tumor is the internal iliac artery.
Conclusion Preoperative interventional embolization can effectively reduce the risk of bleeding during malignant retroperitoneal tumor surgery and improve the perioperative safety of patients. No significant benefit of benign retroperitoneal tumors and no increased risk of bleeding during surgery were observed. Retroperitoneal tumor preoperative embolization should focus on investigating the lumbar, internal iliac, and adrenal arteries.
