Objective: Cerebrovascular disease poses a substantial global health burden and remains a major contributor to mortality and disability. Cerebral digital subtraction angiography (DSA) is an important diagnostic procedure for cerebrovascular disease, but its invasive nature may cause anxiety and poor patient cooperation. This study aimed to evaluate the effects of micro-video combined with situational experience health education on examination efficiency (preparation time, examination time, and puncture time), postoperative adherence (affected-limb immobilization time), patient compliance, psychological status (assessed by the Self-Rating Anxiety Scale [SAS] and Self-Rating Depression Scale [SDS]), and puncture-related complications in patients undergoing DSA. Methods: A total of 100 patients scheduled for cerebral DSA were randomly assigned into control and experimental groups, with 50 patients in each group. The control group received routine health education, whereas the experimental group received micro-video combined with situational experience education from 2 days before to 2 days after the procedure. The outcomes included examination-related indicators, compliance, SAS/SDS scores, and puncture complications. Results: All 100 randomized patients (50 per group) completed the study and were included in the intention-to-treat analysis. Compared with the control group, the experimental group showed a numerically higher compliance rate (92% vs 76%; Pearson χ 2=4.762, P =0.029; Fisher’s exact test, P =0.054; continuity-corrected χ 2=3.646, P =0.056), shorter preparation, examination, and puncture times (all P < 0.001), and greater adherence to postoperative limb immobilization ( P < 0.001). Post-intervention SAS and SDS scores decreased more in the experimental group (both P < 0.001). The total complication rate was numerically lower in the experimental group (4.00% vs 16.00%; Pearson χ 2=4.000, P =0.046; Fisher’s exact test, P =0.092; continuity-corrected χ 2=2.778, P =0.096). However, the compliance-rate and total-complication comparisons were borderline in sensitivity analyses and should be interpreted cautiously. Conclusion: The findings of this randomized controlled trial suggest that micro-video combined with situational experience health education may improve patient compliance and examination efficiency, alleviate anxiety and depression, and reduce puncture-related complications in patients undergoing cerebral DSA. The combined education model appears to be a promising and clinically feasible nursing intervention, but larger multi-center studies are needed to confirm its effectiveness and safety. However, the compliance rate and total complication rate were borderline in sensitivity analyses; therefore, the apparent benefits should be regarded as hypothesis-generating rather than definitive.
