IC seems to be the potent activator of angiogenesis in ischemic tissue. This study provides preliminary data showing that repeated short ischemic stimuli may reduce critical ischemic injury by promoting angiogenesis.
SummaryObjectiveBuerger’s disease and atherosclerosis obliterans (ASO) are two peripheral arterial diseases (PAD) that are frequently encountered. The aim of this study was to compare quality of life (QOL) in patients with Buerger’s disease and ASO.MethodsWe prospectively followed 86 patients who were admitted to our hospital due to ASO or Buerger’s disease. Their ischaemia was evaluated according to the clinical category chronic limb ischaemia at the time of hospital admission and at six and 12 months. The QOL was measured at the time of hospital admission and at six and 12 months with the Short Form Health Status Survey (SF-36) and Vascular Quality of Life Questionnaire (VASCUQOL).ResultsA total of 86 patients with ASO or Buerger’s disease (47 and 39, respectively) were included in the study. Pain parameters from both SF-36 and VASCUQOL scores were lower in patients with Buerger’s disease at the time of hospital admission and at six months. The impairment in QOL was found to be proportional to the extent of chronic limb ischaemia. Conversely, when patients with critical limb ischaemia were evaluated, no difference was observed between those with ASO or Buerger’s disease in terms of QOL. Amputations were found to have a negative effect on quality of life.ConclusionBuerger’s disease had a more pronounced negative effect on QOL than ASO, particularly in terms of pain score. When critical limb ischaemia was considered, ASO and Buerger’s disease impaired quality of life at the same rate.
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.Methods: A standard endograft with suprarenal fixation struts is delivered with its proximal covered edge just below the highest RA in JRAA presenting the ostium of the two renal arteries at a different aortic level and the distance between the highest renal artery and the beginning of the aneurysm (improved landing zone) $10 mm. The low-lying renal artery is maintained patent by the OCh graft (standard SES) delivered from left brachial access (6 Fr). All clinical, anatomical, and operative data were prospectively collected and retrieved for the study analysis.Results: From July 2010 to November 2012, OCh EVAR was offered to 22 consecutive patients considered unfit for JRAA open repair. All procedures were technically successful with aneurysm exclusion and patent OCh graft. One small perioperative type Ia endoleak spontaneously disappeared at the 3-month CT control. One patient died because of acute decompensated heart failure. One patient presented a left hemispheric stroke. The median follow-up of 18 months (range, 7-35) showed aneurysm exclusion in all patients without type I and III endoleaks, SES stenosis, and/ or renal impairment.Conclusions: OCh-EVAR is a straightforward technique that can be employed in selected cases of JRAA, avoiding the more complex and expensive fenestrated EVAR.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
