腹膜后肿瘤是原发于腹膜后间隙的非器官来源的恶性及良性肿瘤。腹膜后肿瘤往往体积巨大且常侵犯周围脏器和大血管,使手术切除困难。目前,对腹膜后肿瘤介入诊疗主要包括:(1)通过血管造影术了解肿瘤的血液供应来源、侵犯血管情况。(2)外科术前对富血供肿瘤进行栓塞,以减少术中出血、减少手术切除难度、减少手术并发症。(3)腹膜后肿瘤切除常需进行血管移植、重建,术后移植血管狭窄时须进行球囊扩张成形术。(4)肿瘤破裂出血、危及生命时,可进行急诊栓塞止血治疗。(5)对无法手术的腹膜后肿瘤,在影像引导下经皮射频消融可以减轻瘤负荷,缓解临床症状。
Retroperitoneal tumor is a non-organ malignant and benign tumor originating in the retroperitoneal space. Retroperitoneal tumors are often bulky and often violate the surrounding organs and blood vessels, making surgical resection difficult. At present, the interventional treatment of retroperitoneal tumors include: (1) angiography to understand the source of blood supply to the tumor, violations of vascular conditions. (2) Surgical preoperative embolization of blood for the tumor to reduce intraoperative bleeding, reduce the surgical resection difficulty and reduce surgical complications. (3) retroperitoneal tumor resection often need for vascular transplantation, reconstruction, postoperative vascular stenosis to be carried out when balloon dilation angioplasty. (4) tumor rupture bleeding, life-threatening, emergency embolization can hemostasis treatment. (5) For unresectable retroperitoneal tumors, percutaneous radiofrequency ablation under the guidance of images can reduce tumor burden and relieve clinical symptoms.
