EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. A Randomised Controlled Trial of Supervised Exercise Regimens and their Impact on Walking Performance, Skeletal Muscle Mass and Calpain Activity in Patients with Intermittent Claudication

C.L. Delaney , M.D. Miller , T.K. Chataway , J.I. Spark

Objectives: Supervised exercise training (SET) is recommended for patients with intermittent claudication (IC). The optimal exercise programme has not been identified, and the potential adverse effects of exercise on these patients warrant consideration. Calpain proteases have been linked with tissue atrophy following ischaemia–reperfusion injury. High calpain activity may therefore cause muscle wasting in claudicants undergoing SET, and skeletal muscle mass (SMM) is integral to healthy ageing. This study assesses the impact of (1) treadmill-based SET alone; and (2) treadmill-based SET combined with resistance training on pain-free walking distance (PFWD), SMM, and calpain activity.

EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. Displacement Forces in Iliac Landing Zones and Stent Graft Interconnections in Endovascular Aortic Repair: An Experimental Study

H. Roos , M. Ghaffari , M. Falkenberg , V. Chernoray , A. Jeppsson , H. Nilsson

Objectives: Stent graft migration influences the long-term durability of endovascular aortic repair. Flow-induced displacement forces acting on the attachment zones may contribute to migration. Proximal fixation of aortic stent grafts has been improved by using hooks, while distal fixation and stent graft interconnections depend on self-expansion forces only. We hypothesized that flow-induced displacement forces would be significant at the distal end, and would correlate with graft movements.

EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. The Hemodynamic Impact of Misalignment of Fenestrated Endografts: A Computational Study

E. Georgakarakos , A. Xenakis , G.S. Georgiadis , C. Argyriou , G.A. Antoniou , N. Schoretsanitis , M.K. Lazarides

Objective: The hemodynamic consequences of misaligned stent-grafts (SG) in fenestrated endografts (EG) have not been adequately studied. Our aim was to study the hemodynamic effects of positional variations of SG, investigating the potential influence on the total displacement forces acting on the EG and the shear stress values at the stented segments.

EUROPEAN JOURNAL OF VASCULAR AND ENDOVASCULAR SURGERY. The “Open” Chimney Graft Technique for Juxtarenal Aortic Aneurysms with Discrepant Renal Arteries

E. Ducasse , S. Lepidi , C. Brochier , S. Deglise , X. Berard , D. Alberti , D. Midy

Objectives: A straightforward original Chimney Graft (CG) protocol has been developed at our institution in selected cases of juxtarenal aortic aneurysm (JRAA). The aim of this study was to present our clinical experience of consecutive series with use of uncovered self-expanding stent (SES) as “Open Chimney” (OCh) in the endovascular repair (EVAR) of JRAA.
