Paclitaxel-coated versus uncoated devices for infrainguinal endovascular revascularisation in chronic limb-threatening ischaemia (SWEDEPAD 1): a multicentre, participant-masked, registry-based, randomised controlled trial.

Background: Drug-coated devices are frequently used in coronary and peripheral interventions, but their effect on amputation risk in peripheral artery disease is unclear. We assessed whether drug-coated devices affect the rate of above-ankle amputation in patients with chronic limb-threatening ischaemia undergoing infrainguinal endovascular revascularisation.

Methods: The Swedish Drug-Elution Trial in Peripheral Arterial Disease 1 (SWEDEPAD 1) was a pragmatic, nationwide, multicentre, participant-masked, registry-based, randomised controlled trial at 22 Swedish centres.

Paclitaxel-coated versus uncoated devices for infrainguinal endovascular revascularisation in patients with intermittent claudication (SWEDEPAD 2): a multicentre, participant-masked, registry-based, randomised controlled trial.

Background: Drug-coated devices are widely used to reduce restenosis after lower limb revascularisation in patients with peripheral artery disease, but their effect on patient-centred outcomes remains unclear. We assessed the effect of paclitaxel-coated devices on clinically important outcomes in patients with intermittent claudication undergoing infrainguinal endovascular revascularisation.

Methods: The Swedish Drug-Elution Trial in Peripheral Arterial Disease 2 (SWEDEPAD 2) was a pragmatic, nationwide, multicentre, participant-masked, registry-based, randomised controlled trial conducted at 22 Swedish vascular centres.

Mortality with Paclitaxel-Coated Devices in Peripheral Artery Disease.

Background: The results of a recent meta-analysis aroused concern about an increased risk of death associated with the use of paclitaxel-coated angioplasty balloons and stents in lower-limb endovascular interventions for symptomatic peripheral artery disease.

Methods: We conducted an unplanned interim analysis of data from a multicenter, randomized, open-label, registry-based clinical trial. At the time of the analysis, 2289 patients had been randomly assigned to treatment with drug-coated devices (the drug-coated-device group, 1149 patients) or treatment with uncoated devices (the uncoated-device group, 1140 patients).

Increased vascular injury reduces the degree of intimal hyperplasia following angioplasty in rabbits.

Background/aims: Formation of intimal hyperplasia following angioplastic procedures can lead to complications, including restenosis and accelerated atherosclerosis. The vessel wall media is a main source of neointimal cells. However, evidence suggests that there are additional cell sources, such as the adventitia.

Endovascular management of acute bleeding arterioenteric fistulas.

The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair.
