Antithrombotic therapy impact on patency and bleeding complications of arteriovenous graft placement in dialysis patients.

Arteriovenous grafts (AVG) can be the only bailout solution for patients who require kidney replacement therapy but are unsuitable for arteriovenous fistula (AVF) creation. Currently, high-level evidence on the effectiveness and safety of antithrombotic therapy in AVG patients is scarce. Following the PICO (patient; intervention; comparator; outcome) model and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a data search of the English literature in PubMed, SCOPUS, Central Cochrane was conducted, until March 1st, 2023 (PROSPERO Protocol Number: CRD42023401785).

Role of Antiplatelet Therapy in Patients Managed for Complex Aortic Aneurysms using Fenestrated or Branched Endovascular Repair.

Objective: Despite the increasing number of fenestrated and branched endovascular aortic repair (F/B-EVAR) procedures, evidence on post-operative antiplatelet therapy is very limited. This study aimed to investigate the role of single antiplatelet therapy (SAPT) vs. double antiplatelet therapy (DAPT) after F/B-EVAR in 30 day and follow up outcomes.

The Role of Aortic Volume in the Natural History of Abdominal Aortic Aneurysms and Post-Endovascular Aortic Aneurysm Repair Surveillance.

There has been a debate about whether maximum diameter can be solely used to assess the natural history of abdominal aortic aneurysm. The aim of the present review is to collect all the available evidence on the role of abdominal aortic aneurysm (AAA) volume in the natural history of AAAs, including small untreated AAAs and AAAs treated by EVAR. The current literature appears to reinforce the role of volume as a supplementary measure for evaluating the natural history of AAA, in both intact AAAs and after EVAR.
