Ninety-four patients with chronic mesenteric ischaemia were included. Only one patient died. After 24 months, the patency of covered stents was better than bare metal stents: 81 versus 49 per cent, P<0.0001. Access site adverse events were more common in covered stent procedures.

Comment: This study does not address whether symptoms were improved alongside patency.

Some 206 of the original 280 patients were available for analysis. Both procedures resulted in durable improvements in disease-specific quality of life (P<0.001). Clinical recurrence was lower after endothermal ablation: 37 versus 59 per cent, P=0.005.

Comment: Endothermal ablation has real long term advantages.

Some 417 patients under 21 years of age were included. Rates of recurrent venous thromboembolism were similarly low after both treatments: 0.66 per cent after six weeks of versus 0.7 per cent after three months of anticoagulation.

Comment: Very low recurrence rates, but six weeks of anticoagulation seems reasonable.
