Application of transcatheter superselective arterial embolization for spinal tumorectomy / 局解手术学杂志

Objective To study the application of transcatheter superselective arterial embolization for the spinal tumorectomy preopera-tive.Methods From January 2009 to September 2015,the data of 65 patients with spinal tumor were collected.Before operation,all the pa-tients had been performed the transcatheter superselective arterial embolization by Seldinger technology,the embolization effect and the blood loss volume were recorded.Results The pathological vertebral body of 62 patients were significantly dyed and the tumor-feeding artery were obvious.But no obvious tumor-feeding artery and the tumor dyeing was found in 3 cases.The tumor-feeding artery positive incidence of angi-ography was 95.3%(62/65).All cases intubation was successful but one.After embolization, the pathological vertebral body was removed completely.The blood loss volume was 500-3 000 mL,with an average (1 400.65 ±230.62) mL.Conclusion The transcatheter superse-lective arterial embolization could reduce the blood loss in spinal tumorectomy and the operation risks,and increase the possibilities of radical resection,which is an effective preoperative intervention.

Comparison of Treatment Effects between Targeting Arterial Embolization before Sacral Chordoma Excision and Temporary Balloon Occlusion of Abdominal Aorta during Sacral Chordoma Surgery / 中国医科大学学报

Objective To compare the clinical efficacy of targeting arterial embolization before sacral chordoma excision and temporary balloon oc-clusion of abdominal aorta during sacral tumors surgery. Methods A total of 34 patients with sacral chordoma were recruited for this study and fol-lowed up. Totally 18 patients received bi-iliac artery,sacrococcygeal artery and other target arteryl embolization before excision(target arterial emboli-zation group),and the other 16 received temporary balloon occlusion of abdominal aorta during surgery(balloon occlusion group). The blood loss during operation,drained blood after operation,operation time and wound healing were recorded. Results The blood loss during operation,drained blood after operation and operation time in targeting arterial embolization group were less than balloon occlusion group. There was no statistical differ-ence in wound healing between the two groups. Conclusion Targeting arterial embolization can be more effective than temporary balloon occlusion of abdominal aorta in the control of blood loss.
