Objective: To investigate the effectiveness of total percutaneous technique in endovascular repair of abdominal aortic aneurysm. Methods: Divide patients into two groups based on random tests. The control group received conventional treatment, and the experimental group received modified treatment. The changes in self-management ability, comfort level and recovery time before and after treatment were compared between the two groups. Results: The comfort level and self-management ability of the experimental group were significantly higher than that of the control group, and the recovery time was significantly shorter than that of the control group. The difference was statistically significant (P<0.05). Conclusion: Puncture suture can safely and effectively repair the intracavity of abdominal aortic aneurysm.
