JOURNAL OF VASCULAR SURGERY. Endograft salvage of hemodialysis accesses threatened by pseudoaneurysms

Alison J. Kinning, BA, Russell W. Becker, DO, Gregory J. Fortin, MD, Robert G. Molnar, MD, Carlo A. Dall Olmo, MD

Objective: Currently, no formal practice guidelines exist regarding the use of endografts to exclude hemodialysis access pseudoaneurysms and prolong access lifespan in dialysis patients. We evaluated the efficacy of percutaneous endograft placement for exclusion of hemodialysis access pseudoaneurysms.

JOURNAL OF VASCULAR SURGERY. Postoperative pain and early quality of life after radiofrequency ablation and mechanochemical endovenous ablation of incompetent great saphenous veins

Ramon R.J.P. van Eekeren, MD , Doeke Boersma, MD , Vincent Konijn, MD , Jean Paul P.M. de Vries, MD, PhD , Michel M.J.P. Reijnen, MP, PhD

Objective: Thermal ablative techniques of varicose veins carry a risk of heat-related complications, including postoperative pain. Mechanochemical endovenous ablation (MOCA) might avoid these complications and reduce postoperative pain because of the absence of thermal energy. This study evaluated postoperative pain and quality of life after radiofrequency ablation (RFA) and MOCA for great saphenous vein (GSV) incompetence.

JOURNAL OF VASCULAR SURGERY. Complications of endovascular grafts in the treatment of pseudoaneurysms and stenoses in arteriovenous access

Jill Nicole Zink, MD, Robert Netzley, MD, Victor Erzurum, MD, Dennis Wright, MD

Objective: Endovascular stent grafts are utilized in the rescue of failing arteriovenous (AV) access. Reports claim the superiority of stent grafts and recommend these as a first-line treatment. We have observed a rise in the number of complications related to stent grafts in our patients. The following study was undertaken to assess the severity of these complications and their effect on access site maintenance.
