The Impact of Mental Health on Patient Outcomes in Peripheral Arterial Disease and Critical Limb Threatening Ischemia and Potential Avenues to Treatment.

The physical consequences of peripheral artery disease (PAD) are well established; however, the impact of comorbid mental health disorders such as depression and anxiety are not well understood. The impact of psychological stress is not only associated with worse perioperative morbidity and mortality but also with a physiologic cascade that accelerates plaque formation. Increasing screening to identify and subsequently treat comorbid mental health disorders is an integral next step in improving outcomes in PAD management. Failure to adequately address social and psychological impact on PAD patients will further widen the gap in disparities faced by high-risk and disenfranchised populations. Integration of mental health professionals, addiction specialists, and community navigators into multidisciplinary care teams can bolster support for PAD patients and improve outcomes.

Unspoken Truths: Mental Health Among Academic Surgeons.

OBJECTIVE: To characterize the current state of mental health within the surgical workforce in the United States. BACKGROUND: Mental illness and suicide is a growing concern in the medical community; however, the current state is largely unknown. METHODS: Cross-sectional survey of the academic surgery community assessing mental health, medical error, and suicidal ideation. The odds of suicidal ideation adjusting for sex, prior mental health diagnosis, and validated scales screening for depression, anxiety, post-traumatic stress disorder (PTSD), and alcohol use disorder were assessed. RESULTS: Of 622 participating medical students, trainees, and surgeons (estimated response rate=11.4%-14.0%), 26.1% (141/539) reported a previous mental health diagnosis. In all, 15.9% (83/523) of respondents screened positive for current depression, 18.4% (98/533) for anxiety, 11.0% (56/510) for alcohol use disorder, and 17.3% (36/208) for PTSD. Medical error was associated with depression (30.7% vs. 13.3%, P <0.001), anxiety (31.6% vs. 16.2%, P =0.001), PTSD (12.8% vs. 5.6%, P =0.018), and hazardous alcohol consumption (18.7% vs. 9.7%, P =0.022). Overall, 13.2% (73/551) of respondents reported suicidal ideation in the past year and 9.6% (51/533) in the past 2 weeks. On adjusted analysis, a previous history of a mental health disorder (aOR: 1.97, 95% CI: 1.04-3.65, P =0.033) and screening positive for depression (aOR: 4.30, 95% CI: 2.21-8.29, P <0.001) or PTSD (aOR: 3.93, 95% CI: 1.61-9.44, P =0.002) were associated with increased odds of suicidal ideation over the past 12 months. CONCLUSIONS: Nearly 1 in 7 respondents reported suicidal ideation in the past year. Mental illness and suicidal ideation are significant problems among the surgical workforce in the United States.

Finding Comfort in Discomfort Reflecting on Stories Told.

INTRODUCTION: The 2022 Presidential Address for the Association for Academic Surgery was focused on better understanding the personal and professional challenges faced by surgeons during the COVID-19 pandemic. METHODS: As part of this work, we embarked on a listening tour, inviting surgeons from all over the country to tell us their stories. This led to forming a panel of five selected participants based on how their stories crosscut many of the most prevalent themes during those conversations. Here, we present thematic excerpts of the 2022 presidential panel, intending to capture that moment and challenge surgeons to contribute to an ever-evolving movement that pushes us to unpack some of our greatest areas of discomfort. RESULTS: We found that, in many ways, the COVID-19 pandemic brought into focus what many surgeons from marginalized groups have historically struggled with. Dominant themes from these conversations included the role of surgery in informing identity, the tensions between personal and professional identity, the consequences of maintaining medicine as an apolitical space, and reflections on initiatives to address inequities. Panelists also reflected on the hope that these conversations are part of a movement that leads to sustained change rather than a passing moment. CONCLUSIONS: The primary goal of this work was to center voices and experiences in a way that challenges us to become comfortable with topics that often cause discomfort, validate experiences, and foster a community that allows us to rethink what and whom we value in surgery. We hope this work serves as a guide to having these conversations in other institutions.

Social media for patient engagement.

Who better to serve as "Dr. Google" than an actual doctor? Patients often present with a list of symptoms and turn to their favorite search engine to understand their constellation of symptoms. In this editorial, we attempt to address the following key elements in surgeons' use of social media (#SoMe4Surgery) as a tool for patient engagement: marketing, demystifying and differentiating the surgical specialty, a fast track to the latest specialty-specific guidelines and recommendations, and combatting medical misinformation. The increased social media presence in the medical space can be used to improve health literacy and simplify the navigational process of one's healthcare journey. These platforms can humanize physicians, make them more accessible, and bridge the gap that sometimes exists, preventing patients from moving to their next step in care due to fear. The extent of social media use in healthcare far surpasses this brief discussion, and it is up to the individual user to exercise the appropriate uses and responsibilities regarding patient communication.

Impact of socioeconomic disparities on major lower extremity revascularization complications.

INTRODUCTION: Low socioeconomic status (SES), distance lived from hospital, and insurance status are well documented in the literature to increase the risk of post-operative morbidity and mortality for some disease processes however there is a paucity of data regarding how this association impacts patients with peripheral artery disease (PAD). This study aimed to evaluate if SES, distance lived from hospital, and insurance status increased the risk of developing major graft failure in patients undergoing revascularization procedures for symptomatic PAD in a prospective, observation study. METHODS: In this prospective, observational study, all patients undergoing lower extremity revascularization (endovascular or open) were included from December 2020 to February 2022. Demographic factors, insurance status, operative details, and median income and distance from hospital were documented through chart review. Complications were defined as thrombosis/occlusion of the revascularized vessel or bypass graft or infection of the distal wound or surgical incision wound. Univariate and multivariate analysis were performed comparing patients that developed complications and those that did not. This project was undertaken at the Massachusetts General Hospital and was governed by the Institutional Review Board (IRB: 2020P000263) all patients agreed to participation via informed written consent prior to enrollment in the study. RESULTS: A total of 108 patients were enrolled in the study of which 94 underwent successful revascularization procedures. Of those 94 patients, 38 (40.4%) underwent open bypass, 39 (41.5%) underwent endovascular revascularization, and 17 (18.1%) underwent a hybrid approach. There were no significant differences in post-operative outcomes between operative approaches. Twenty-five patients (28.7%) experienced major revascularization complications as defined as re-occlusion of the treated vessel/thrombosis of the bypass graft (n = 13) or development of post-operative infection (n = 12). There was no significant difference in median income ($75,295 vs $87,757, p = NS), distance lived from hospital, (27.4 miles vs. 29.7 miles, p = NS), or type of insurance (private 24% vs 26%, government 76% vs 73%, p = NS between patients that experienced complications versus those that did not have complications. These findings suggest the risk of major graft failure is independent of a patient's socioeconomic status, distance lived from hospital, or insurance type in patients undergoing revascularization procedures for PAD. CONCLUSION: While socioeconomic factors impact access to and have a known association with negative outcomes, complications in patients with PAD appear to be independent of these factors. To mitigate the negative outcomes in patients with peripheral artery disease, a focus should be on patient risk factors and modifiable medical factors that contribute to adverse outcomes.

Impact of anticoagulation/antiplatelet therapy on femoropopliteal bypass graft outcomes.

BACKGROUND: Anticoagulant and antiplatelet (AC/AP) medications have been reported to improve bypass graft patency, however, the optimal AC/AP strategy remains unclear in the heterogenous peripheral artery disease population. METHODS: A multi-institutional retrospective review utilizing the Research Patient Data Registry database from 1995 to 2020 was performed for all patients who underwent femoropopliteal bypass procedures. Electronic medical records were used to obtain demographic information, comorbidities, smoking status, operative details (bypass target), postoperative AC/AP medications, postoperative complications, and long-term outcomes and were reviewed for the cohort. Cox proportional hazards model was used to determine independent risk factors for major adverse limb events (MALE) after bypass. MALE was defined as reintervention for patency or major amputation of index limb (above- or below-knee amputation). RESULTS: A total of 1421 patients underwent femoropopliteal bypass between 1995 and 2020 throughout five institutions included in this study. Complete data were available for 1292 of the 1421 patients (90.9%). The indications for bypass included intermittent claudication (21.4%), rest pain (30.3%), tissue loss (33.5%), and nonatherosclerotic disease (14.8%). Distal bypass targets comprised above-knee (38.6%) and below-knee (61.4%) popliteal arteries. Patients were divided into six groups based on postoperative AC/AP use including none (n = 57 [4.4%]), monoantiplatelet therapy (n = 587 [45.4%]), dual AP therapy (n = 214 [16.6%]), AC alone (n = 73 [5.7%]), AC + monoantiplatelet therapy (n = 319 [24.7%]), and AC + dual AP therapy (n = 42 [3.3%]). Postoperative bleeding complications were low for both hematoma (3.7%) and pseudoaneurysm (0.7%). There was no difference in bleeding complications across AC/AP groups (hematoma, P = .61; pseudoaneurysm, P = .31). After adjusting for patient factors, below-knee bypass target (hazard ratio [HR], 1.25; 95% confidence interval [CI], 1.04-1.52; P = .019) and bypass for tissue loss (HR, 1.40; 95% CI, 1.04-1.88; P = .028) were independent predictors for MALE. Great saphenous vein conduit trended toward protection for MALE, compared with prosthetic grafts (HR, 0.84; 95% CI, 0.70-1.01; P = .06). No AC/AP regimen was associated with of MALE, even stratifying by above-knee and below-knee bypass cohorts. The median follow-up period was 2 years. CONCLUSIONS: Among patients undergoing femoropopliteal bypass grafting, no combination of AC or AP medications was associated with improved graft patency; however, a below-knee target and tissue loss were associated with adverse limb events. AC and AP regimen may be individualized after bypass with regard to other concomitant medical comorbidities.

A systematic review of thromboelastography utilization in vascular and endovascular surgery.

OBJECTIVE: Thromboelastography (TEG) is diagnostic modality that analyzes real-time blood coagulation parameters. Clinically, TEG primarily allows for directed blood component resuscitation among patients with acute blood loss and coagulopathy. The utilization of TEG has been widely adopted in among other surgical specialties; however, its use in vascular surgery is less prominent. We aimed to provide an up-to-date review of TEG utilization in vascular and endovascular surgery. METHODS: Using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a literature review with the Medical Subject Headings (MeSH) terms "TEG and arterial events", "TEG and vascular surgery", "TEG and vascular", "TEG and endovascular surgery", "TEG and endovascular", "TEG and peripheral artery disease", "TEG and prediction of arterial events", "TEG and prediction of complications ", "TEG and prediction of thrombosis", "TEG and prediction of amputation", and "TEG and amputation" was performed in Cochrane and PubMed databases to identify all peer-reviewed studies of TEG utilization in vascular surgery, written between 2000 and 2021 in the English language. The free-text and MeSH subheadings search terms included diagnosis, complications, physiopathology, surgery, mortality, and therapy to further restrict the articles. Studies were excluded if they were not in humans or pertaining to vascular or endovascular surgery. Additionally, case reports and studies with limited information regarding TEG utilization were excluded. Each study was independently reviewed by two researchers to assess for eligibility. RESULTS: Of the 262 studies identified through the MeSH strategy, 15 studies met inclusion criteria and were reviewed and summarized. Literature on TEG utilization in vascular surgery spanned cerebrovascular disease (n = 3), peripheral arterial disease (n = 3), arteriovenous malformations (n = 1), venous thromboembolic events (n = 7), and perioperative bleeding and transfusion (n = 1). In cerebrovascular disease, TEG may predict the presence and stability of carotid plaques, analyze platelet function before carotid stenting, and compare efficacy of antiplatelet therapy after stent deployment. In peripheral arterial disease, TEG has been used to predict disease severity and analyze the impact of contrast on coagulation parameters. In venous disease, TEG may predict hypercoagulability and thromboembolic events among various patient populations. Finally, TEG can be utilized in the postoperative setting to predict hemorrhage and transfusion requirements. CONCLUSIONS: This systematic review provides an up-to-date summarization of TEG utilization in multiple facets of vascular and endovascular surgery.

Late Type 1A Endoleaks: Associated Factors, Prognosis and Management Strategies.

BACKGROUND: Unlike periprocedural Type 1A endoleaks, late appearing proximal endoleaks have been poorly described. METHODS: We studied all elective EVAR from 2010 -2018 in a single institution. Late endoleaks were defined as those appearing after 1 year. We used Cox regression to study factors associated with late Type 1A endoleaks and survival. RESULTS: Of 477 EVAR during the study period, 411 (86%) had follow-up imaging, revealing 24 Type 1A endoleaks; 4 early and 20 late. Freedom from Type 1A endoleaks was 99%, 92-81% at 1, 5 and 8 years with a median time to occurrence of 2.5 years (.01-8.2 years). On completion angiogram, only 10% of patients with a late Type 1A had a proximal endoleak, and 60% had no endoleak. Only 21% of late Type 1As were diagnosed on routine 1-year CT angiogram, but 79% had stable or expanding sacs. Two thirds (65%) of the patients eventually diagnosed with late Type 1A endoleaks had previously been treated for other endoleaks, mostly Type 2 (10/13). Age (HR 1.07/year [1.02-1.12], P = 0.01), neck diameter >28mm (HR 3.5 [1.2-10.3], P = 0.02), neck length <20mm (HR 3.0 [1.1-8.6], P = 0.04), and neck angle>60 degrees (HR 3.4 [1.5-7.9], P = 0.004) were associated with higher rates of Type 1A endoleak, but not female sex, endograft, or the use of suprarenal fixation. 2 patients had proximal degeneration and 5 experienced graft migration. There were 2 ruptures (10%), and 13 patients underwent repair with 5 open conversions. Median survival after late Type 1A repair was 6.6 years (0-8.4 years). CONCLUSION: Late appearing Type 1A endoleaks have a high rate of rupture and present significant diagnostic and management challenges. Careful surveillance is needed in patients with hostile neck anatomy and those who undergo intervention for other endoleaks. Adverse neck anatomy may be better suited for open repair or fenestrated/branched devices rather than conventional EVAR.

The current status of the diversity pipeline in surgical training.

OBJECTIVE: Recent initiatives have emphasized the importance of diversity, equity, and inclusion in academic surgery. Racial/ethnic disparities remain prevalent throughout surgical training, and the "diversity pipeline" in resident recruitment and retention remains poorly defined. METHODS: Data was retrospectively collected using two separate datasets. The Association of American Medical Colleges database was used to obtain demographic data on US medical school graduates. The US Graduate Medical Education annual report was used to obtain demographic data on surgical residents. Wilcoxon signed-rank test was used to compare racial/ethnic distribution within surgical residency programs with graduating medical students. Linear regression analysis was performed to analyze population trends over time. RESULTS: The study population included 184,690 surgical residents from 2011 to 2020. Nine resident cohorts were created according to surgical specialty - general surgery, neurosurgery, ophthalmology, orthopedic surgery, otolaryngology, plastic surgery, cardiothoracic surgery, urology, and vascular surgery. Among surgical programs, White residents were overrepresented in 8 of 9 specialties compared to the concurrent graduating medical student class for all years (p < 0.01 each, no difference in ophthalmology). Black residents were underrepresented in 8 of 9 specialties (p < 0.01 each, no difference in general surgery). Asian representation was mixed among specialties (4 overrepresented, 1 equal, 4 underrepresented), as was Hispanic representation (5 overrepresented, 4 equal) (p < 0.01 each). CONCLUSIONS: These data suggest that racial/ethnic disparities are inherent to the process of recruitment and retention of surgical residents. Efforts to improve the "diversity pipeline" should focus on mentorship and development of minority medical students and creating an equitable learning environment.

Comparison of treatment options for aortic necks outside standard endovascular aneurysm repair instructions for use.

OBJECTIVE/BACKGROUND: Endovascular aneurysm repair (EVAR) is associated with worse outcomes in patients whose anatomy does not meet the device instructions for use (IFU). However, whether open surgical repair (OSR) and commercially available fenestrated EVAR (Zenith Fenestrated [ZFEN]) represent better options for these patients is unknown. METHODS: We identified all patients without prior aortic surgery undergoing elective repair of abdominal aortic aneurysms with neck length ≥4 mm at a single institution with EVAR, OSR, and ZFEN. We applied device-specific aneurysm neck-related IFU to EVAR patients, and a generic EVAR IFU to ZFEN and OSR patients. Long-term outcomes were studied using propensity scores with inverse probability weighting. We compared outcomes in patients undergoing EVAR by adherence to IFU and outcomes by repair types in the subset of patients not meeting IFU. RESULTS: Of 652 patients (474 EVAR, 34 ZFEN, 143 OSR), 211 had measurements outside of standard EVAR IFU (109 EVAR [23%], 27 ZFEN [80%], and 74 OSR [52%]). Perioperative mortality was 0.5% overall. For EVAR, treatment outside the IFU was associated with significantly higher adjusted rates of long-term type IA endoleak (22% at 5 years compared to 2% within IFU, hazard ratio [HR]: 5.8 [3.1-10.9], P < .001), and lower survival (5- and 10-year survival: 56% and 34% vs 81% and 53%, HR: 2.3 [1.2-4.3], P = .01). There was no difference in reinterventions or open conversion. In patients not meeting IFU, ZFEN was associated with higher adjusted rates of reinterventions (EVAR as referent: HR: 2.6 [1.5-4.4, P < .001), whereas OSR and EVAR patients experienced similar reintervention rates (HR: 0.7 [0.4-1.1], P = .13). Patients outside the IFU experienced lower mortality with OSR compared with either EVAR (HR: 0.4 [0.2-0.9], P = .005) or ZFEN (HR: 0.3 [0.1-0.7], P = .002). When restricted to patients outside the IFU deemed fit for open repair, OSR patients remained associated with lower adjusted mortality compared with ZFEN (HR: 0.2 [0.1-0.5], P < .001), but statistical significance was lost in the comparison to EVAR (HR: 0.6 [0.3-1.1], P = .1). CONCLUSIONS: Treatment outside device-specific IFU is associated with adverse long-term outcomes. Open surgical repair is associated with higher long-term survival in patients who fall outside of the EVAR IFU and should be favored over EVAR or ZFEN in suitable patients. A three-vessel-based fenestrated strategy may not be a durable solution for difficult aortic necks, but more data are needed to evaluate the performance of newer, four-vessel devices.
