- The research covers a range of applications, from understanding complex brain rhythms to modeling auditory processing and investigating the effects of neural regulation on behavior.
Purpose: To report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR) of an infrarenal aortic aneurysm (AAA) and survey our surgical colleagues in the UK for their use of this bypass procedure.
Methods: A 74-year-old woman who had an EVAR complicated by renal failure secondary to malposition of the stent-graft underwent successful delayed renal revascularization with hepatorenal and splenorenal bypasses. This case prompted a literature review and preparation of an online 6-part questionnaire regarding the incidence and management of renal impairment following EVAR.
Background: Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) are both associated with excellent technical, clinical and patient-reported outcomes for the treatment of varicose veins. The aim of this study was to compare the techniques in a randomized clinical trial.
Methods: Consecutive patients with primary great saphenous vein reflux were randomized to EVLA (980 nm) or RFA (VNUS ClosureFAST) at a single centre.
Objectives: A number of modalities are now available for the treatment of varicose veins. The aim of the study was to investigate the factors considered important by patients when contemplating treatment of their varicose veins.
Methods: Consecutive new patients referred to a vascular surgery service were invited to complete a short anonymous questionnaire prior to their consultation.
Objectives: The aim of this study was to evaluate postoperative pain following endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) and identify risk factors for increased pain.
Methods: Patients undergoing either segmental RFA (VNUS Closure Fast, VNUS Medical Technologies, San Jose, California) or EVLA (980 nm) for varicose veins completed a preoperative disease-specific quality-of-life questionnaire (Aberdeen Varicose Vein Questionnaire [AVVQ]) and a diary card recording postoperative pain, return to normal activities, and return to work. Median 3- and 10-day pain scores were calculated.
Objectives: A variety of endovenous therapies for the treatment of superficial venous incompetence are currently available. The aim of this study was to evaluate the prevalence of endovenous techniques used by consultant vascular surgeons in the United Kingdom.
Methods: An anonymous online survey of 16 multiple choice questions relating to the nature and provision of treatment for varicose veins was devised.
Objectives: The peri-operative use of antiplatelet, anticoagulant and other drugs for patients undergoing carotid endarterectomy (CEA) is unclear and consensus is lacking. This study aimed to assess the current peri-operative practice of European vascular surgeons with respect to antiplatelet and other medications for patients undergoing CEA.
Design: Online questionnaire study.
