RESUMO

OBJECTIVE: Left vertebral artery revascularization is indicated in surgery involving zone 2 of the aortic arch and is typically accomplished indirectly via subclavian artery revascularization. For aberrant left vertebral anatomy, direct revascularization is indicated. Our objective was to compare the outcomes of direct vertebral artery revascularization with indirect subclavian artery revascularization for treating aortic arch pathology and to identify predictors of mortality. METHODS: A retrospective cohort study was conducted at a single tertiary hospital, including patients who underwent open or endovascular vertebral artery revascularization from 2005 to 2022. Those who underwent direct vertebral revascularization were compared with those who were indirectly revascularized via subclavian artery revascularization. The outcomes of interest were a composite outcome (any of death, stroke, nerve injury, and thrombosis) and mortality. Univariate logistic regression models were fitted to quantify the strength of differences between the direct and indirect revascularization cohorts. Cox regression was used to identify mortality predictors. RESULTS: Of 143 patients who underwent vertebral artery revascularization, 21 (14.7%) had a vertebral artery originating from the aortic arch. The median length of stay was 10 days (interquartile range, 6-20 days), and demographics were similar between cohorts. The incidence of composite outcome, bypass thrombosis, and hoarseness was significantly higher in the direct group (42.9% vs 18.0%, P = .019; 33.3% vs 0.8%, P < .0001; 57.1% vs 18.0%, P < .001, respectively). The direct group was approximately three times more likely to experience the composite outcome (odds ratio, 3.41; 95% confidence interval, 1.28, 9.08); similarly, this group was approximately six times more likely to have hoarseness (odds ratio, 5.88; 95% confidence interval, 2.21, 15.62). There was no significant difference in mortality rates at 30 days, 1, 3, 5, and 10 years of follow-up. Age, length of hospital stay, and congestive heart failure were identified as predictors of higher mortality. After adjusting for these covariates, the group itself was not an independent predictor of mortality. CONCLUSIONS: Direct vertebral revascularization was associated with higher rates of composite outcome (death, stroke, nerve injury, and thrombosis), bypass thrombosis and hoarseness. Patients with aberrant vertebral anatomy are at higher risks of these complications compared with patients with standard arch anatomy. However, after adjusting for other factors, mortality rates were not significantly different between the groups.

RESUMO

While shared decision-making (SDM) is generally considered to be the standard in current clinical practice, strict application of SDM can result in adverse outcomes in certain contexts. This article examines two illustrative cases-antibiotic over-prescription and decision-making at or near the end of life-to highlight how strictly applied SDM can result in suboptimal outcomes. The article continues to describe how strategies from libertarian paternalism, particularly default setting, framing, and nudging, can be valuable tools in supplementing strict applications of SDM, resulting in improved outcomes and patient care on both individual and societal levels.

RESUMO

The topic of futility has been intensely debated in bioethical discourse. Surgical futility encompasses considerations across a continuum of care, from decision-making during initial triage, to the choice to operate or refrain from operating on the critically ill, to withdrawal of life-supporting care. Determinations over futility may result in discord between providers and patients or their families, who might insist that treatment be provided at all costs to sustain life. In this manuscript, we will explore some of the possible sources for and manifestations of these disputes, and describe approaches by which to resolve them. Part I will briefly address some of the reasons that families ask for life-sustaining measures against medical advice in the surgical setting. These include variable determinations of both the quality of life and the inherent value of life (stemming from religious, cultural, and personal beliefs). Part II will detail some general instances in which physicians and surgeons can override requests to provide futile treatment, namely: instances of resource scarcity, interventions which carry a high probability of harm, and those that carry significant moral distress. To conclude, Part III will provide concrete guidelines for navigating futility, making an argument for individual case-based communication models in surgical decision-making.

RESUMO

BACKGROUND: Epilepsy affects over 500,000 children in North America of whom 30% have drug-resistant epilepsy. Advancements with neurotechnologies show promising benefits, but the perceptions of these procedures by youth is unknown. METHODS: We conducted semistructured interviews with 10 youth in British Columbia, Canada who underwent procedures for drug-resistant epilepsy involving different forms of neurotechnology (subdural grids, vagus nerve stimulation, responsive neurostimulation). Interviews were analyzed using the constant comparative qualitative method. RESULTS: Four major thematic categories emerged from the interviews. Treatment values, impact of the disorder, personal context, and impact of neurotechnology. CONCLUSIONS: Besides the predictable goal of seizure reduction, a desire for autonomy and the importance of trust in the medical team emerged as dominant values within the 4 thematic categories that were explicit to the use of new neurotechnologies for the management of drug-resistant epilepsy.

RESUMO

Supply-side interventions such as prescription drug monitoring programs, "pill mill" laws, and dispensing limits have done little to quell the burgeoning opioid crisis. An increasingly popular demand-side alternative to these measures - now adopted by 38 jurisdictions in the USA and 7 provinces in Canada - is court-mandated involuntary commitment and treatment. In Massachusetts, for example, Part I, Chapter 123, Section 35 of the state's General Laws allows physicians, spouses, relatives, and police officers to petition a court to involuntarily commit and treat a person whose alcohol or drug abuse poses a likelihood of serious harm. This paper explores the ethical underpinnings of this law as a case study for others. First, we highlight the procedural and substantive standards of Section 35 and evaluate the application of the law in practice, including the frequency with which it has been invoked and outcomes. We then use this background to inform an ethical critique of the law. Specifically, we argue that the infringement of autonomy and privacy associated with involuntary intervention under Section 35 is not currently justified on the grounds of a lack of evidenced benefits and a risk of significant of harm. Further ethical concerns also arise from a lack of standard of care provided under the Section 35 pathway. Based on this analysis, we advance four recommendations for change to mitigate these ethical shortcomings.
