Radiation exposure in an endovascular aortic aneurysm repair program after introduction of a hybrid operating theater
A hybrid operating theater (HOT) enables optimal image quality, improved ergonomics, and excellent sterility for complex endovascular and hybrid procedures. We hypothesize that the commissioning of a new HOT involves a learning curve. It is unclear how steep the learning curve of these advanced HOTs is. The main purpose of this research was to evaluate radiation exposure parameters in a new HOT for a team of vascular surgeons experienced with infrarenal endovascular aneurysm repair (EVAR) procedures in a conventional operating room with a mobile C-arm.

Juxtarenal endovascular therapy with fenestrated and branched stent grafts after previous infrarenal repair
The treatment strategy for proximal aortic disease or type I endoleak after previous infrarenal repair has traditionally been open surgery. As endovascular treatment options with fenestrated and branched stent grafts increasingly rival open surgery for juxtarenal and pararenal aortic aneurysms, secondary proximal repair may similarly be performed endovascularly. Fenestrated stent grafts are individually tailored to each patient, whereas a more readily available “off-the-shelf” branched stent graft is often suitable in more urgent settings.

Carotid artery atherosclerotic stenosis is a preventable major cause of stroke, but there is still a need for definition of high-risk plaque in asymptomatic patients who might benefit from interventional therapies. Several image markers are recommended to characterize unstable plaques.

A systematic review of high-intensity interval training as an exercise intervention for intermittent claudication
Intermittent claudication (IC) is the most common symptom of peripheral arterial disease, which significantly affects walking ability, functional capacity and quality of life. Supervised exercise programs (SEP) are recommended as first-line treatment, but recruitment and adherence rates are poor. The time required to complete a SEP is the most common barrier to participation cited by patients who decline. High-intensity interval training (HIIT) is more time efficient than current SEPs and therefore has the potential to overcome this barrier. (Source: Journal of Vascular Surgery)

In the diagnosis of peripheral artery disease (PAD), the ankle-brachial index plays an important role. However, results of the ankle-brachial index are unreliable in patients with severe media sclerosis.

Invited commentary
The systemic review and meta-analysis by Hu et  al suggests that the direct thrombin inhibitor bivalirudin is superior to unfractionated heparin (UFH) in peripheral endovascular procedures. Specifically, bivalirudin had lower odds ratios of periprocedural mortality, major adverse cardiovascular events, net adverse clinical events, perioperative myocardial infarction, major vascular complications, and minor vascular complications. These are intriguing data, given the fact that probably most vascular surgeons still primarily use UFH periprocedurally for intraluminal interventions, usually to maintain an activated clotti...
