The endovascular treatment for celiac axis aneurysms: curative effect analysis of 16 cases

Objective: To discuss the curative effect of endovascular interventional treatment for celiac axis aneurysms (CAA). Methods: The clinical data of 16 consecutive patients with CAA, who were admitted to authors' hospital to receive endovascular intervention from June 2011 to December 2015, were retrospectively analyzed. Pure coil embolization was employed in 11 patients, coil embolization together with covered stent implantation was adopted in 4 patients, and multiple overlapping bare stent deployment was conducted in one patient. Follow-up CT angiography was carried out at 3, 6 and 12 months after the treatment and once a year thereafter. The clinical outcomes in both perioperative and follow-up periods were recorded, and the results were evaluated. Results: The technical success rate was 100%. The average operation time was (91.56 ± 39. 30) min. The mean hospitalization time was (5.25 ± 1.44) days. All patients were regularly followed up for 1-54 months, and the total survival rate was 100%. Follow-up CT angiography showed that no coil migration, stent displacement, enlargement of aneurysm size, rupture or recanalization of aneurysm, etc. were observed. Conclusion: For the treatment of CAA, endovascular management carries higher technical success rate with low incidence of complication and mortality. Therefore, this therapy is safe and effective.
