Objective: Endovascular aneurysm repair (EVAR) is a widely used option for patients with suitable vascular anatomy who have a large infrarenal abdominal aortic aneurysm (AAA). Neck diameter is the primary anatomical determinant of EVAR eligibility and device durability. Doxycycline has been proposed to stabilise the proximal neck after EVAR.

Article Synopsis
  • The SYMPLICITY HTN-3 trial aimed to evaluate the safety and effectiveness of the Symplicity system for treating patients with uncontrolled hypertension, initially showing safety after 6 months but not efficacy.
  • Conducted across 88 centers in the USA, the trial involved adults aged 18-80 with treatment-resistant hypertension and compared outcomes of renal artery denervation versus a sham control over a follow-up period of 36 months.
  • The final report details long-term blood pressure changes, analyzing results from participants in both the renal denervation group and those who crossed over from the sham group after the 6-month mark.

The field of Interventional Radiology is said to have begun in 1964, when Dotter successfully restored circulation to an 82-year-old woman's leg with critical limb ischemia and gangrene by percutaneously dilating a localized stenosis of the superficial femoral artery using a Teflon catheter. The dilation catheter was revolutionary in the inception of angioplasty, and progress evolved with the development of angioplasty balloons. As angioplasty became more widely utilized, the focus turned to improving its results.

Minority patients such as Blacks, Hispanics, and Native Americans are disproportionately impacted by critical limb ischemia and amputation due to multiple factors such as socioeconomic status, type or lack of insurance, lack of access to health care, capacity and expertise of local hospitals, prevalence of diabetes, and unconscious bias. The Society of Interventional Radiology Foundation recognizes that it is imperative to close the disparity gaps and funded a Research Consensus Panel to prioritize a research agenda. The following research priorities were ultimately prioritized: (a) randomized controlled trial with peripheral arterial disease screening of at-risk patients with oversampling of high-risk racial groups, (b) prospective trial with the introduction of an intervention to alter a social determinant of health, and (c) a prospective trial with the implementation of an algorithm that requires criteria be met prior to an amputation.
