摘要
<jats:sec><jats:title>Introduction:</jats:title><jats:p> All arteriovenous fistula/grafts options should be exhausted before haemodialysis is carried out via central venous catheters (CVC). CVCs carry high morbidity and mortality risks and in some patients, the central veins could be exhausted. In these patients, an arterioarterial prosthetic loop (AAPL) or straight graft can be the only option for haemodialysis. A systematic review was thus carried out to look at the use of arterioarterial graft for haemodialysis, with regards to dialysis adequacy, complications, and patency rates. </jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p> An electronic search was performed using the EMBASE and MEDLINE databases from inception until June 2017. Study retrieval was conducted according to PRISMA guidelines. </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> A total of eight studies published between 1976 and 2017 were identified for pooled analysis. The studies were retrospective cohort in design and reported data on 151 patients. Primary patency rate ranged from 67%-94.5% at six months to 54%-61% at 36 months, with secondary patency rates from 83%-93% at six months to 72%-87% at 36 months. All studies documented satisfactory haemodialysis. Although limited by the size of the cohort of patients studied, patients with end-to-side grafts did not suffer from distal ischaemia when the graft occluded unlike patients who had their graft sutured as end-to-end. </jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p> This review highlights the potential benefit of arterioarterial grafts for dialysis as an alternative vascular access option. As a result, this review calls for registry-based multicentre study to evaluate this treatment arm as an alternative option when all AVF/AVG options are exhausted. </jats:p></jats:sec>
