Abstract: Objective To explore the application value of problem-based learning (PBL) in clinical teaching of intracranial aneurysms management. Methods The standardized training students in Department of Neurosurgery of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from August 2018 to August 2019 were randomly assigned to the observation group and control group, and the PBL teaching method was used in observation group and lecture-based learning (LBL) teaching method in control group. A one-month teaching course included basic theoretical knowledge, clinical practice and surgical strategy. After completing all the teaching courses, the two groups were tested by examination, and the scores of the two groups were compared. Results A total of 32 students were included, with 16 ones in each group. The test results showed that there was no statistical difference in score of basic theoretical knowledge between the two groups (77.3±1.20 vs. 76.9±0.98, P =0.310), the scores of clinical practice (84.7±3.11 vs. 81.8±2.93, P =0.011) and surgical strategy (73.0±2.58 vs. 70.5±2.88, P =0.015) in PBL group were higher than that in LBL group. Conclusions For the clinical teaching of surgical treatment of intracranial aneurysms, the PBL teaching method is more conducive to improving the clinical practice ability and cultivating dialectical thinking ability of surgical strategy for standardized training students.
