Article Abstract
Background: Portal vein (PV) resection is used increasingly in pancreatic resections. There is no agreed policy regarding anticoagulation.
Methods: A systematic review was performed to compare studies with an anticoagulation policy (AC+) to no anticoagulation policy (AC-) after venous resection.
Results: There were eight AC+ studies (n = 266) and five AC- studies (n = 95). The AC+ studies included aspirin, clopidogrel, heparin or warfarin. Only 50% of patients in the AC+ group received anticoagulation. There were more prosthetic grafts in the AC+ group (30 versus 2, Fisher's exact P < 0.001). The overall morbidity and mortality was similar in both groups. Early PV thrombosis (EPVT) was similar in the AC+ group and the AC- group (7%, versus 3%, Fisher's exact P = 0.270) and was associated with a high mortality (8/20, 40%). When prosthetic grafts were excluded there was no difference in the incidence of EPVT between both groups (1% vs 2%, Fisher's exact test P = 0.621).
Conclusion: There is significant heterogeneity in the use of anticoagulation after PV resection. Overall morbidity, mortality and EPVT in both groups were similar. EPVT has a high associated mortality. While we have been unable to demonstrate a benefit for anticoagulation, the incidence of EPVT is low in the absence of prosthetic grafts.

Left Atrial Appendage Occlusion vs Anticoagulants in Dialysis With Atrial Fibrillation.
JAMA Netw Open

Department of Internal Medicine, University of Arkansas for Medical Sciences, Little Rock.
Importance: Patients with kidney failure (KF) receiving long-term dialysis have increased incidence of atrial fibrillation (AF). Patients with KF and AF have increased risk of stroke, death, and bleeding compared with age-matched cohorts. In KF, the use of oral anticoagulants (OACs) increases hemorrhage risk, offsetting potential benefits and making left atrial appendage occlusion (LAAO) a potentially promising solution for risk reduction in AF.

Department of Anaesthesia and Intensive Care Medicine, Royal Papworth Hospital, Cambridge Biomedical Campus, Cambridge, United Kingdom.
Objective: Postoperative intraluminal thrombosis after frozen elephant trunk replacement has been reported to occur with a frequency of 6% to 17% and is associated with poor outcomes. The purpose of this institutional review is to analyze thrombosis rate, predisposing patient and operative factors, and assess different anticoagulation regimens.
Methods: This retrospective cohort study includes 174 patients operated on over 10 years.

Department of pharmacy, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, People's Republic of China.
Background: The use of new oral anticoagulants (NOACs) is becoming increasingly widespread, but data on their adverse reactions are still incomplete. Further analysis based on data from the Drug Adverse Reaction Center is needed to guide safe clinical use.
Methods: A retrospective analysis was performed on 281 cases of rivaroxaban and 48 cases of dabigatran etexilate-related ADR reported by medical institutions collected by a provincial Food and Drug Administration from 2018 to 2023.

Research on health-related quality of life (HRQoL) among thalassemia patients in Jordan remains limited. This study aimed to evaluate HRQoL outcomes in patients with thalassemia and examine associations with psychosocial, medical, and clinical factors. A cross-sectional study was conducted among β-thalassemia major patients attending the Thalassemia Unit at Princess Rahma Educational Hospital for Children.

Background: Failure to rescue (FTR), defined as death after a surgical complication, is strongly impacted by systems-level care processes. The purpose of this study was to optimize the definition of FTR by developing the methodology for, and evaluating the subsequent impact of, adding complications to the Society of Thoracic Surgeons (STS) definition.
Methods: Patients undergoing coronary artery bypass grafting and/or valve operations from 2011-2024 in Michigan were included.
