Virtual assistants, broadly defined as digital services designed to simulate human conversation and provide personalized responses based on user input, have the potential to improve health care by supporting clinicians and patients in terms of diagnosing and managing disease, performing administrative tasks, and supporting medical research and education. These tasks are particularly helpful in vascular surgery, where the clinical and administrative burden is high due to the rising incidence of vascular disease, the medical complexity of the patients, and the potential for innovation and care advancement. The rapid development of artificial intelligence, machine learning, and natural language processing techniques have facilitated the training of large language models, such as GPT-4 (OpenAI), which can support the development of increasingly powerful virtual assistants. These tools may support holistic, multidisciplinary, and high-quality vascular care delivery throughout the pre-, intra-, and postoperative stages. Importantly, it is critical to consider the design, safety, and challenges related to virtual assistants, including data security, ethical, and equity concerns. By combining the perspectives of patients, clinicians, data scientists, and other stakeholders when developing, implementing, and monitoring virtual assistants, there is potential to harness the power of this technology to care for vascular surgery patients more effectively. In this comprehensive review article, we introduce the concept of virtual assistants, describe potential applications of virtual assistants in vascular surgery for clinicians and patients, highlight the benefits and drawbacks of large language models, such as GPT-4, and discuss considerations around the design, safety, and challenges associated with virtual assistants in vascular surgery.

Increasing evidence highlights the adverse impact of frailty and reduced physiologic reserve on surgical outcomes. Therefore, identification of frailty is essential for older adults being evaluated for vascular surgery procedures. Numerous frailty assessment tools are available to quantify the level of frailty and assist in preoperative decision making for these older patients. This review evaluates traditional and novel frailty metrics for their scientific validation, limitations, and clinical utility in vascular surgery decision-making.

There is variation in the management of small aneurysms in the United States today, with some surgeons moving forward with elective repair and others practice ongoing surveillance. Literature exists to suggest that small aneurysms are repaired at a higher rate than should be considered acceptable, and this represents a deviation from current standards of care. To best understand the optimal care of this patient population, this article aims to evaluate the current management of small aneurysms, review contemporary guidelines and the literature behind them, and assess the appropriateness of surgical management of small aneurysms.

In the past decade, technologies to treat venous pathologies have increased dramatically, to the benefit of an often underserved and overlooked population of patients with venous disease. However, given the rapid release of various technologies, including venous-dedicated stents and thrombectomy devices across varied venous pathologies, evidence-based guidelines have been slow to develop. When discussing appropriateness of care, one needs to consider optimal patient selection, technical approach, medical management, and surveillance protocols, to name a few. All of which, in the venous space, are currently widely varied in practice. The future of deep venous work is limitless, but multicenter, randomized controlled trials are needed to optimally treat patients with venous disease.

A dramatic increase in the number of vascular procedures performed in the office-based laboratory setting has been observed since 2008, when the Centers for Medicare and Medicaid Services increased reimbursement for procedures performed in the ambulatory setting. We sought to evaluate the appropriateness of arterial intervention in the office-based laboratory and patient selection. This systematic review was conducted with a search of Google Scholar and PubMed using the following search terms: office-based lab, outpatient, angioplasty, patient selection, arterial, and appropriateness. More than 500 publications were screened and 14 publications related to the topic were selected. The existing literature that examined patient selection for intervention in the outpatient setting, rates of complications after outpatient procedures, and short-term data on the safety and efficacy of these procedures is discussed. Gaps were identified in current knowledge about the long-term outcomes of peripheral arterial interventions performed in the office-based laboratory setting, as well as existing guidelines for the management of patients with peripheral arterial disease.

Intermittent claudication (IC) is a phenotype of peripheral artery disease that is characterized by pain in the lower extremity muscles during activity that is relieved by rest. Medical management, risk factor control, smoking cessation, and exercise therapy have historically been the mainstays of treatment for IC, but advances in endovascular technology have led to increasing use of peripheral vascular interventions in this patient population. There are meaningful differences in published society guidelines and appropriate use criteria relevant to the management of IC, especially regarding indications for peripheral vascular interventions. The current review aims to highlight similarities and differences between major society recommendations for the management of IC, and to discuss practice trends, disparities, and evidence gaps in the use of peripheral vascular interventions for IC in the context of existing guidelines.

Chronic limb threatening ischemia (CLTI) poses a significant treatment challenge for vascular surgeons, interventionalists, podiatrists, and associated medical specialists. The evidence for what constitutes appropriate care is rapidly evolving and new treatment options are in constant development. This review examines the current guidelines for CLTI care, as well as reported outcomes for multiple care strategies in this patient population, including revascularization and medical optimization. We performed a literature review of the PubMed database, reviewing articles that reported outcomes for CLTI care between 2000 and 2023, and described these outcomes as they relate to the current state of CLTI treatment. Significant data are still forthcoming regarding CLTI care, but widespread adoption of appropriate CLTI care is essential for the treatment of this vulnerable population.

Aortic dissection is a catastrophic, life-threatening event. Its management depends on the anatomic location of the intimal tear (type A v B) and the clinical presentation in type B aortic dissection. In this article, the current evidence supporting clinical practice, gaps in knowledge, and the need for more rigorous research and higher-quality studies are reviewed.

Appropriate use criteria (AUC) aim to impact the provision of high-value care. This scoping review identified AUC regarding the procedural and operative treatment of cardiovascular disease and described the evolution of AUC in this space over time, including changes in the focus, strategy, and language of AUC. The summative presentation of these AUC identifies elements of AUC that may lead to successes in, and barriers to, implementation across disease processes, specialties, and societies. AUC topics include coronary artery disease, peripheral artery disease, valvular disease, venous disease, renal artery stenosis, and mesenteric ischemia, among others.
