Interlock 可解脱弹簧圈在脾动脉瘤腔内治疗中的应用.

Objective: To investigate the application value of Interlock detachable coils for the endovascular treatment of splenic aneurysms. Methods: The clinical data of 36 patients with splenic aneurysms treated with Interlock detachable coils from February 2016 to February 2019 were retrospectively analyzed, including 10 cases of male, 26 cases of female, 31 cases of true aneurysms. 5 cases of pseudo splenic aneurysm were diagnosed by ultrasound or CTA preoperation. An angiogram was performed immediately after embolization to determine the technical success rate. The blood routine, pancreatic amylase and aortic CTA were monitored during the perioperative period and at 2 weeks, 3 months and 6 months after surgery to observe the incidence of complications. Results: 6 patients underwent embolization of the aneurysm at the proximal end and the tumor cavity, and the rest only embolized the spleen aneurysm tumor cavity. Intraoperative DSA angiography showed that the occlusion rate of the splenic aneurysm was higher than 97%. A total of 128 Interlock coils were used during the operation, of which 104 were diamond-shaped and 24 were ordinary 2D. The average diameter of the coils is 6.3± 4.2(2-12)mm, the average length is 16± 13.5(3-32)mm, and the average size of the tumoris 40.6± 12.5(15-70)mm. No complications occurred during the perioperative period. The average follow-up was 10.0± 3.2(6-15) months. After 1 month, 2 cases had spleen infarction, 7 cases had mild abdominal pain and low fever. In all cases, no tumor cavity recanalization and tumor enlargement were observed. Conclusion: Interlock can release the coils safely and effectively for the treatment of splenic aneurysms. It has a wide application prospect and its long-term efficacy needs long-term follow-up observation. [ABSTRACT FROM AUTHOR]
