conducted. The overall effects of year and procedure groups were significant (P ¼ .014; Fig 1). The hazard ratio of OSR pre-2007 was 1.54 (95% confidence interval, 0.75-3.16) indicating higher risk, and the hazard ratio of EVAR was 0.58 (95% confidence interval, 0.23-1.42) indicating a lower risk.Conclusions: Survival after RAAA has improved since 2007, primarily driven by an "EVAR-first" approach despite increased overall comorbidities. Survival in patients after open aneurysm repair has also improved; however, the difference did not reach statistical significance. EVAR is the best first-line therapy for rAAA at experienced centers.
Patients with peripheral arterial disease (PAD) have compromised blood flow to their extremities as a result of arterial narrowing. PAD is often associated with impairment in endothelial function which is exaggerated by injury from processes related to cardiovascular risk factors such as ageing, hypertension, hyperlipidemia, diabetes, smoking, and obesity [1]. Furthermore, patients with diabetes often have calcified arteries making standard non-invasive testing non diagnostic [2]. With increase in diabetes prevalence and concomitant PAD, a new non-invasive assessment method of arterial function that has the potential to reflect both arterial tone and response to ischemia reperfusion may be valuable. We have developed a peripheral arterial tonometry (PAT) system (previously described, [3]) that is capable of measuring pulsatility in peripheral digits. We complemented our system with simultaneous peripheral temperature measurements that could not only add value in understanding PAD, but also aid in clinical diagnoses. In this investigation, we characterized our system on healthy individuals before using it on patients suffering from arterial disease in future investigations.
endografts and longer and more radially supported balloon-expanded and self-expanding stent grafts has simplified these procedures. Moreover, increased familiarity with proper sizing, snorkel course and configuration, and factors for seal optimization has enhanced the appeal of this approach in many difficult clinical scenarios.
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.
