Stanford A型主动脉夹层患者四肢血压测量现状及其差异对预后的影响因素研究

Objective To investigate the current status of limb blood pressure measurement and differences in extremities of patients with Stanford type A aortic dissection(TAAD) upon admission, and to discuss the influencing factors on patient prognosis. Methods A retrospective study was conducted on 375 patients with TAAD admitted to a tertiary hospital in Guangzhou from January 1, 2023, to December 31, 2024, 100 cases were included in this study. Statistical analyses were performed using independent sample t-test, chi-square test, and Fisher's exact test. Results Among the 375 patients with TAAD, 263 patients who did not measure limb blood pressure after admission and 12 patients who did not undergo surgery were excluded. Only 100 patients measured limb blood pressure on admission, of which 63 patients had limb blood pressure differences. The proportion of limb blood pressure measured by TAAD was low(26.67%), and the proportion of limb blood pressure differences was high(63.00%). There were statistically significant differences in limb blood pressure differences among TAAD patients in terms of history of hypertension, length of hospital stay, aortic cross-clamping time and cardiopulmonary bypass time(P<0.05). Conclusion Four-limb blood pressure differences in TAAD patients can predict patient prognosis to some extent and have positive implications for individualized treatment, nursing care, and prognosis improvement in such patients.
