popularJuly’s top 10 most popular items include more from this year’s Society for Vascular Surgery (SVS) Vascular Annual Meeting (VAM 2022; 15–18 June, Boston, USA), new research on vascular health disparities between men and women, and an interview with Alexander Zimmermann.

1. Artificial intelligence can predict risk of complications after endovascular aneurysm repair

Artificial intelligence (AI) models can be developed to predict the risk of postoperative complications after endovascular aneurysm repair (EVAR) with “high accuracy,” research presented at this year’s Society for Vascular Surgery (SVS) Vascular Annual Meeting (VAM 2022; 15–18 June, Boston, USA) demonstrated. 

2. Terumo Aortic announces first commercial implant of the Thoraflex Hybrid device in the USA

Following the recent approval by the US Food and Drug Administration (FDA) of the Thoraflex Hybrid frozen elephant trunk (FET) device for the treatment of patients with complex aortic arch disease, Terumo Aortic has now announced the first commercial implant of the device in the USA.

3. Recruitment complete in FEVAR study for on-label use with Bentley BeGraft as bridging stent

Bentley has announced that recruitment is now complete in the fenestrated endovascular aortic aneurysm repair (FEVAR) study that uses the company’s BeGraft peripheral balloon-expandable covered stent as a bridging stent in complex aortic aneurysms.

4. Intraoperative vascular mapping during haemodialysis access “should be incorporated into routine practice”

Intraoperative ultrasonographic venous mapping is a useful tool to evaluate vessel suitability for arteriovenous fistula (AVF) creation, Yana Etkin (Zucker School of Medicine at Hofstra/Northwell, Lake Success, USA) concluded at this year’s Society for Vascular Surgery (SVS) Vascular Annual Meeting (VAM 2022; 15–18 June, Boston, USA).

5. “No pain, no gain” approach improves walking ability with peripheral arterial disease

Walking for exercise at a pace that induced pain or discomfort improved walking ability among people with peripheral arterial disease (PAD), according to new research published today in the Journal of the American Heart Association (JAHA).

6. Female sex is associated with additional treatments following surgical therapies for intermittent claudication

A new US study has found that female sex is associated with more reinterventions after surgical treatment for intermittent claudication. Additionally, guideline-directed medical therapy, including aspirin and statin use, was used less frequently among female compared with male patients in both the preoperative and postoperative settings.

7. Profile: Alexander Zimmermann

Alexander Zimmermann (University Hospital Zurich, Zurich, Switzerland) tells Vascular News about his career to date, beginning with a rotation in vascular surgery that opened up “a whole new world of medicine” to his directorship of the Department of Vascular Surgery at the University of Zurich. He outlines his current research interests, anticipates how the field might develop in the next decade, and recalls his most memorable case—the first physician-modified fenestrated endovascular aneurysm repair (FEVAR) procedure he ever performed.

8. Ra Medical Systems receives FDA 510(k) clearance for the Dabra 2.0 catheter

Ra Medical Systems has announced receipt of US Food and Drug Administration (FDA) 510(k) clearance for the company’s Dabra 2.0 catheter as part of the Dabra excimer laser system. A company press release details that the catheter features enhancements including a braided overjacket design that is intended to improve deliverability and kink resistance when navigating tortuous anatomy, as well as a six-month shelf life.

9. Female sex is associated with reintervention and mortality following elective EVAR

Women are more likely to die within five years of having elective surgery to repair an abdominal aortic aneurysm (AAA) or need repeat surgery, according to a recent study.

10. AVeVA study confirms benefit of covered stent placement in graft-vein anastomotic stenosis treatment

A prospective, multicentre study involving the Covera vascular covered stent (BD) has confirmed the benefits of immediate, post-percutaneous transluminal angioplasty (PTA) placement of the device in treating arteriovenous graft (AVG) venous anastomotic stenosis when anatomically and clinically suitable. Writing in the Journal of Vascular and Interventional Radiology (JVIR), Bart Dolmatch (Palo Alto Medical Foundation, Mountain View, USA) and colleagues report a 30-day freedom from safety-related events of 96.4% and a six-month target lesion primary patency (TLPP) of 70.3% with the Covera stent.
