Objective: To investigate the three-dimensional reconstruction technique and intraoperative postural changes in the interventional treatment of cerebral aneurysm.

Methods: A total of 52 cases involving patients with a definite CT diagnosis of cerebral aneurysm in our hospital were selected from July 2014 to August 2015. The cases were randomly and equally divided into observation and control groups using the random number table method. The patients in the two groups underwent interventional embolization. The observation group underwent three-dimensional CT angiography and the control group underwent rotational angiography with three-dimensional reconstruction (3D R-DSA). The correlation between aneurysm neck and adjacent parental arteries was investigated.

Results: The aneurysm longitudinal diameter 6.65 ± 2.21 and neck width 4.24 ± 1.21 in the observation group were significantly higher than those in the control group 5.54 ± 1.12 and 3.11 ± 1.01, respectively, and the difference was statistically significant (p<0.01). In the >3 mm and ≤ 3 mm aneurysm diameter groups, the correlations between the aneurysm neck and adjacent parental arteries of patients showed statistical significance (p<0.05). Overall results of the aneurysm neck and adjacent parental arteries of the patients in the two groups showed a statistically significant difference (p<0.05).

Conclusion: Rotational DSA combined with three-dimensional vascular reconstruction and appropriate intraoperative position changes enables machineries to reach complicated angles and ensures the clear display of the relationships between the aneurysm and adjacent parental arteries and between aneurysm neck and size. These effects improve the success rates of operations.
