ReviewAssessing the quality of available patient reported outcome measures for intermittent claudication: a systematic review using the COSMIN checklist.
The aim was to critically appraise, compare, and summarize the quality of the measurement properties of all available disease specific patient reported outcome measures (PROMs) on health related quality of life and functional status validated in patients with intermittent claudication (IC). ⋯ The quality of the validation of most disease specific PROMs for IC is alarming, hampering all conclusion based on these PROMs. Considering the results, the PAD quality of life questionnaire (PADQOL), Intermittent claudication questionnaire (ICQ) and the Vascular quality of life questionnaire (VascuQol) might be appropriate PROMs for health related quality of life, while the Walking impairment questionnaire (WIQ) and Estimate ambulation capacity by history questionnaire (EACH-Q) appear suitable PROMs for functional status. However, all PROMs require further validation studies to fill the gaps in their measurement properties. The shortcomings highlighted in this review should be taken into account when interpreting PROM results.

Comparative StudyFinite element analysis in asymptomatic, symptomatic, and ruptured abdominal aortic aneurysms: in search of new rupture risk predictors.
To compare biomechanical rupture risk parameters of asymptomatic, symptomatic and ruptured abdominal aortic aneurysms (AAA) using finite element analysis (FEA). ⋯ From different FEA derived parameters, PWRI distinguishes most precisely between asymptomatic and symptomatic AAAs. If elevated, this value may represent a negative prognostic factor for asymptomatic AAAs.

Observational StudyUnderstanding administrative abdominal aortic aneurysm mortality data.
Administrative data in the form of Hospital Episode Statistics (HES) and the Scottish Morbidity Record (SMR) have been used to describe surgical activity. These data have also been used to compare outcomes from different hospitals and regions, and to corroborate data submitted to national audits and registries. The aim of this observational study was to examine the completeness and accuracy of administrative data relating to abdominal aortic aneurysm (AAA) repair. ⋯ The SMR-01 returns contain multiple errors. There also appears to be a systematic bias that reduces apparent 30-day mortality. Using these data alone to describe or compare activity or outcomes must be done with caution.

Multicenter StudyThe impact of early pelvic and lower limb reperfusion and attentive peri-operative management on the incidence of spinal cord ischemia during thoracoabdominal aortic aneurysm endovascular repair.
Spinal cord ischemia (SCI) is a devastating complication following endovascular thoracoabdominal aortic aneurysm (TAAA) repair. In an attempt to reduce its incidence two peri-procedural changes were implemented by the authors in January 2010: (i) all large sheaths are withdrawn from the iliac arteries immediately after deploying the central device and before cannulation and branch extension to the visceral vessels; (ii) the peri-operative protocol has been modified in an attempt to optimize oxygen delivery to the sensitive cells of the cord (aggressive blood and platelet transfusion, median arterial pressure monitoring >85 mmHg, and systematic cerebrospinal fluid drainage). ⋯ The early restoration of arterial flow to the pelvis and lower limbs, and aggressive peri-operative management significantly reduces SCI following type I-III TAAA endovascular repair. With the use of these modified protocols, extensive TAAA endovascular repairs are associated with low rates of SCI.

Endovascular repair with chimney technique for juxtarenal aortic aneurysm: a single center experience.
Chimney endovascular aneurysm repair (Ch-EVAR) is a cheap and immediately available method for treatment of juxtarenal aortic aneurysms (JRAAs). The aim of this study was to report experiences and results with balloon expandable stent (BES) for Ch-EVAR. ⋯ Ch-EVAR can be used to treat JRAAs with suitable anatomical conditions. However, complications of type I endoleak were not uncommon, and, therefore, further studies are required to prove its efficiency for JRAAs.
