Bypass versus Angioplasty in Severe Ischaemia of the Leg (BASIL) trial: An intention-to-treat analysis of amputation-free and overall survival in patients randomized to a bypass surgery-first or a balloon angioplasty-first revascularization strategy.

Summary of BASIL trial recommendations: The BASIL trial suggests that those SLI patients who are likely to live ≥2 years are probably better served by a BSX-first strategy, preferably with vein. [37] Those SLI patients who are unlikely to live 2 years, and possibly those in whom vein is not available for bypass, are probably better served by a BAP-first strategy because they are unlikely to survive to reap the longer-term benefits of surgery, they may be more likely to suffer surgical morbidity and mortality, and because angioplasty is significantly less expensive than surgery in the short-term.

The surgical management and outcomes of dialysis access-associated steal syndrome (DASS)

Al Shakarchi J, et al. Surgical techniques for haemodialysis access-induced distal ischaemia. J Vasc Access. 2016 Jan-Feb;17(1):40-6.

Results: Following strict inclusion/exclusion criteria by two reviewers, twenty-seven studies of surgical interventions were included and divided into subgroups for banding, DRIL, PAI and RUDI procedures. Both DRIL and banding procedures were found to have high rates of symptomatic relief. In addition, the DRIL has a significantly lower rate of early thrombosis than banding although the more recent papers seem to suggest that early thrombosis is less of a problem in banding. PAI and RUDI showed some promise but there were too few studies to be able to make any clear conclusions.

Conclusions: All four procedures have high success rate in relieving ischaemic symptoms with the DRIL procedure having a significantly better vascular access patency rate than other techniques, although further well designed studies are required to compare all four surgical techniques.
