Background: Stanford type A aortic dissection (STAAD) is a critical cardiovascular disease, and surgical procedure is the first-choice treatment. The classical surgical procedure still leads to a high mortality rate and neurological complications. In this study, we introduce a new modified Sun's procedure and investigate the association between the branch-first technique and the postoperative outcomes of patients with STAAD.
Methods: A total of 108 consecutive patients with STAAD who underwent arch replacement and stent elephant trunk procedure at Beijing Anzhen Hospital between July, 2017 and November, 2018 were included in the analysis. The patients were divided into two groups: the branch-first group and the classic group. The branch-first group and the classic group comprised 24 patients (22.2%) and 84 patients (77.8%), respectively.
Results: Patients in the branch-first group had a significantly shorter cardiopulmonary bypass (CPB) duration (172.4±29.9 194.9±47.4 min; P=0.035), Intensive care unit (ICU) stay [17.0 (14.6-38.2) 42.1 (19.7-87.2) hours; P<0.001], and mechanical ventilation time [15.5 (11.9-40.0) 19.0 (17.0-45.6) hours; P=0.018] than patients in the classic group. The branch-first was associated with a reduction in postoperative neurological complications in all models.
Conclusions: The benefits of the branch-first technique, including lower CPB duration, better bilateral cerebral perfusion, and higher nasopharyngeal temperature during hypothermic arrest, contributed to a shortened recovery time for patients after surgery.

Objectives: Despite the potential spillover effect, the optimal duration of dual antiplatelet therapy for minor stroke within 72 hours of symptom onset is still uncertain.
Methods: Safety and Efficacy of Aspirin-Clopidogrel in Acute Noncardiogenic Minor Ischemic Stroke (National Institutes of Health Stroke Scale (NIHSS) score≤5) is a prospective cohort study involving patients with minor ischaemic stroke within 72 hours of symptom onset. The DAPT group was further categorised into three subgroups: shorter duration (<10 days), short duration (10-21 days) and long duration (>21 days).

Background: Cerebral protection strategies have been investigated since the introduction of aortic arch surgery and have been modified over the centuries. However, the cerebral protective effects of unilateral and bilateral antegrade cerebral perfusion are similar, with opportunities for further improvement.
Methods: A total of 30 patients who underwent total arch surgery were enrolled in this study.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was: 'Can a "branch-first" approach to aortic arch replacement be safely utilized in Stanford type A acute aortic syndromes?' Altogether 64 papers were found using the reported searches, of which 10represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated.

Not only systolic blood pressure (SBP) but also diastolic blood pressure (DBP) increases the risk of recurrence in the short- or long-term outcomes of stroke. The interaction between DBP and antiplatelet treatment for China stroke patients is unclear. This multicenter, observational cohort study included 2976 minor ischemic stroke patients.

Objective: Sparce evidence suggests superiority of total arch replacement with the branch-first technique and antegrade cerebral perfusion over conventional techniques with respect to morbidity and mortality. Thus, we aimed to compare perioperative outcomes of patients undergoing traditional total arch replacement versus branch-first total arch replacement.
Methods: We retrospectively reviewed 144 patients undergoing total arch replacement from January 2017 to December 2021.
