Recovery of the hibernating cavernosum by penile revascularization.

Objective: Chronic ischemia-related cavernous dysfunction is considered irreversible. However, in certain patients, cavernous function appears to recover with penile revascularization. In this study, we investigated a potential cavernous dysfunction reversibility from a clinical perspective. Patients and Methods: We involved 93 young patients in the study with arterial erectile dysfunction (ED) (median age: 30 years). Erectile function tests were performed according to the standard operating procedures of the International Society of Sexual Medicine. Among the participants, 63 and 30 displayed pure arteriogenic and mixed vasculogenic (due to both arterial insufficiency and cavernous dysfunction) ED, respectively. Penile revascularization was performed by anastomosing the inferior epigastric artery to the dorsal artery. The ED treatment success was considered from a score of at least 24 on the International Index of Erectile Function-6. Results: Our results proved that penile revascularization cured 92.1% and 73.8% of the patients with pure arteriogenic and mixed vasculogenic ED, respectively (Kaplan-Meier method, log-rank test: no significant difference). The required time for curing 50% of the patients was 10.5 and 10.0 months for pure arteriogenic and mixed vasculogenic ED, respectively, indicating no recovery delay in patients with mixed vascular ED. Furthermore, the cavernous dysfunction degree did not influence cavernous function recovery. Conclusion: Penile revascularization cured ED in 73.8% of the patients with mixed vasculogenic ED. Cavernous dysfunction appears to be reversible in certain cases. Furthermore, we observed no delay in functional recovery compared to participants with healthy cavernous function. These two discoveries suggest that cavernous function recovery after penile revascularization is similar to the concept of hibernating myocardium in ischemic myocardium. Although cavernous dysfunction is considered irreversible, it could be reversed in multiple cases with blood flow restoration to the cavernous tissue.

A Multi-Institutional Study from the US ROPE Consortium Examining Factors Influencing Vascular Surgery Specialization among General Surgery Residents.

BACKGROUND: There remains a progressive projected deficit in the vascular surgery (VS) workforce for decades yet to come. Despite the rise of an expanding integrated VS residency pathway, the fellowship training model remains critical in supporting our future workforce. Therefore, it is imperative to understand the resident and program-specific factors that influence VS specialization among general surgery (GS) residents. METHODS: Data from the US Resident OPerative Experience (ROPE) Consortium, comprising 20 Accreditation Council for Graduate Medical Education (ACGME)-accredited GS residency programs across the United States, were queried for resident demographics and residency program-related details. Logistic regression analysis was used to identify factors associated with VS specialization. RESULTS: From 2010 to 2020, a total of 1343 graduating GS residents were included in the study. Of these, 135 (10.1%) pursued VS fellowship training. Residents pursuing VS were more frequently male (80.7% vs 62.8%, p<0.0001) and younger (median 32 vs 33 yr, p=0.03) compared with other GS residents. Racial and ethnic group, underrepresented in medicine (URiM) status, and international medical graduate (IMG) status were similar between VS and non-VS groups. Residency program-level details were also similar between groups, including program type (university vs community-based), region, size, resident volume, dedicated research experience, and National Institutes of Health funding. Dedicated vascular rotations were common among all GS programs (95.4%), and total months spent on a VS rotation (median 4 vs 4.5 mo, p=0.11) did not differ among residents pursuing VS and all other residents. The presence of a collocated traditional (5+2) VS fellowship (91.1% vs 90.4%, p=0.79) or integrated (0+5) VS residency (56.3% vs 55.0%, p=0.77) were also similar between groups. On multivariate analysis, only male sex (odds ratio 2.34, 95% confidence interval, 1.50-3.81, p<0.001) was associated with pursuing VS fellowship. Factors that did not impact VS specialization included resident age, URiM status, IMG status, program volume, dedicated research experience, or total months spent on a VS rotation. CONCLUSIONS: In this multi-institutional study, we did not find any program-specific factors that influence VS specialization among GS residents. Notably, the presence of a collocated 0+5 residency or 5+2 fellowship program did not appear to deter GS residents from pursuing VS fellowship. These data suggest that individual factors, such as mentorship, may be more impactful in recruiting GS residents to the VS specialty.

The Geographic Distribution of Vascular Surgeons and Trainees by State in 2023.

OBJECTIVE: Approximately 1.4 vascular surgeons/100,000 persons are estimated to fulfill current patient needs in the United States (US), but an ongoing shortage exists. The aims of this study are to provide an updated nationwide state-by-state workforce analysis and compare the distribution of practicing vascular surgeons and training opportunities. METHODS: Vascular surgeons in the US were identified using the National Provider Identifier registry in 2023. Only board-certified and actively licensed vascular surgeons were included. To estimate the number of vascular surgery graduates per year in each state, integrated residency and fellowship-matched positions (trainees) were ascertained from the National Resident Matching Program website. Surgeons and trainees were totaled by state, and densities were calculated using the 2020 US Census Bureau state populations. These two cohorts were also examined together using simple linear regression and geographic mapping. RESULTS: This study included 3399 board-certified vascular surgeons and 228 newly matched trainees. The average densities of vascular surgeons and trainees in the US are 1/100,000 persons and 0.06/100,000 persons, respectively. The five states with the lowest densities of vascular surgeons are AR, ND, NV, OK, and WY, averaging 0.4/100,000 persons. Eight states (AK, ID, KS, ND, NM, NV, RI, WY) had zero training programs offering positions in 2023 and ranked in the lowest quartile for the number of practicing vascular surgeons (Figure 1). Simple linear regression demonstrated a statistically significant correlation between state rates of vascular surgeons and trainees (p < 0.001). CONCLUSION: States with zero training positions also have the fewest vascular surgeons per capita. Statewide attention to expanding vascular surgery training opportunities targeted in these areas could positively impact the current maldistribution and shortage of vascular surgeons.

The difficulties and solutions in operationalising a hybrid operating room.

As the population ages and grows, health services must evolve in ways to offer versatile patient care, whilst improving patient outcomes and maintaining long-term economic viability. A facility assisting in the provision of such healthcare is the hybrid operating room (HOR): a specialised suite allowing simultaneous radiological and surgical diagnostics and therapeutics in a single episode of care. Versatile and customizable, the HOR is utilised by a broad range of subspecialties in elective and emergency settings, including (but not limited to) vascular surgery, trauma surgery and interventional radiology. Though the benefits of hybrid techniques to patient care are well known, the actual steps in operationalising the HOR can be challenging if not considered and coordinated appropriately. The intention of this narrative review is to highlight issues and suggest solutions in the design and commissioning of an HOR. Key areas in need of specific attention include stakeholder involvement, economic feasibility, suite location, workflow planning, hybrid equipment choice, and team organisation.

A surgical approach to complex regional pain syndrome with neurogenic thoracic outlet syndrome in a reoperation patient.

Thoracic outlet syndrome (TOS) and complex regional pain syndrome (CRPS) are two etiologies of chronic pain. TOS is a group of conditions that occur due to compression of the neurovascular structures of the upper extremity while CRPS is a disorder characterized by chronic and unremitting pain. This case highlights the experience of a 22-year-old female who presented following a traumatic injury to her left arm and was initially diagnosed with neurogenic TOS and later CRPS. Over a 10-year-period, she underwent a total of four operations to try and address her debilitating pain. In our third-time reoperation, symptoms of both pathologies nearly completely resolved with extensive neurolysis of the left brachial plexus and application of a scar tissue barrier.

A case report of a patient with severe & debilitating arm pain: Neurogenic thoracic outlet syndrome and complex regional pain syndrome are two disorders with the potential to cause severe and debilitating long-term pain, typically in an arm or leg. These two disorders are hard to diagnose, and patients can have variable responses to treatment. This case discussed a young woman who has severe pain of her left arm which eventually progress to the point that she had lost all meaningful use of the arm. After 8 years of treatments and four surgeries, she improved and began to regain her arm function.

Prevalence of Varicose Veins Among Surgeons: A Cross-Sectional Study.

Background Extended periods of standing, obesity, female sex, and older age are risk factors associated with a higher probability of developing varicose veins (VV). This study aimed to determine the prevalence of VV among surgeons in public hospitals in Makkah, Saudi Arabia, and to identify the risk factors associated with this condition.  Methodology This is a descriptive cross-sectional study based on a validated online questionnaire distributed via hospital WhatsApp (Meta Platforms Inc., Menlo Park, CA) groups conducted between January and June 2024. The inclusion criteria of this study were surgeons of both sexes and any age group working in the selected hospitals in Makkah City, who agreed to participate in the study. The exclusion criteria were any other healthcare workers from outside the surgical field. We included 192 participants, and Epi Info software (Centers for Disease Control and Prevention, Atlanta, GA) was used to calculate the sample size. The data were collected, reviewed, and then fed into IBM SPSS Statistics software for Windows version 21 (IBM Corp., Armonk, NY). Every participant filled out a consent form. The university ethics committee of Umm Al-Qura University, Makkah, granted ethical permission. Result This study comprised 192 surgeons in Makkah hospitals. Twenty-eight surgeons were either diagnosed with VV or had signs of VV. Varicose veins were detected among 50% of thoracic surgeons, 42.9% of pediatric surgeons, and 26.3% of orthopedic surgeons. The most reported risk factors were a family history of VV (17%), hypertension (16%), and diabetes mellitus (14%). Surgeons aged 40 years or older had a higher prevalence of VV than younger ones. Also, 55.6% of obese surgeons had VV compared to 7.8% of others with average weight. Conclusion We found that VV is a common problem, particularly among individuals with predisposing factors, such as long standing hours, smoking, pregnancy, and obesity. We found that surgeons specializing in thoracic and pediatric specialties and female surgeons were more likely to be affected by VV. Preventive measures, such as avoiding prolonged standing, wearing compression stockings, and maintaining a healthy lifestyle, are recommended.

Left ventricular end-diastolic pressure response to spinal anaesthesia in euvolaemic vascular surgery patients.

PURPOSE: Regional anaesthesia techniques provide highly effective alternative to general anaesthesia. Existing evidence on the effect of spinal anaesthesia (SA) on cardiac diastolic function is scarce. This study aimed to evaluate the effects of a single-injection, low-dose SA on left ventricular end-diastolic pressures (LVEDP) using echocardiography in euvolaemic patients undergoing elective vascular surgery. METHODS: This is a prospective study in adult patients undergoing elective vascular surgery with SA. Patients with contraindications for SA or significant valvular disease were excluded. During patients' evaluations fluid administration was targeted using arterial waveform monitoring. All patients underwent echocardiographic studies before and after SA for the assessment of indices reflective of diastolic function. LVEDP was evaluated using the E/e' ratio. Blood samples were drawn to measure troponin and brain natriuretic peptide (BNP) levels before and after SA. RESULTS: A total of 62 patients (88.7% males, 71.00 ± 9.42 years) were included in the analysis. In total population, end-diastolic volume (EDV, 147.51 ± 41.36 vs 141.72 ± 40.13 ml; p = 0.044), end-systolic volume (ESV, 69.50 [51.50] vs 65.00 [29.50] ml; p < 0.001) and E/e' ratio significantly decreased (10.80 [4.21] vs. 9.55 [3.91]; p = 0.019). In patients with elevated compared to those with normal LVEDP, an overall improvement in diastolic function was noted. The A increased (- 6.58 ± 11.12 vs. 6.46 ± 16.10; p < 0.001) and E/A decreased (0.02 ± 0.21 vs. - 0.36 ± 0.90; p = 0.004) only in the elevated LVEDP group. Patients with elevated LVEDP had a greater decrease in E/e' compared to those with normal LVEDP (- 0.03 ± 2.39 vs. - 2.27 ± 2.92; p = 0.002). CONCLUSION: This study in euvolaemic patients undergoing elective vascular surgery provides evidence that SA improved LVEDP.

Study Protocol for a Focus Group Discussion About the Patients' Perspective on Carotid Endarterectomy.

INTRODUCTION: The outcomes of carotid surgery are commonly evaluated using parameters such as mortality and stroke. The importance of these parameters is based on doctors' and scientific perspectives. Presently, patient centered health care aims to value the evaluation from patients' perspective, mostly using Patient-Reported Outcomes (PROs). The true significance of outcomes of carotid surgery that matter most to the patients is largely unknown. The aim of this study is to identify and verify the patients' perspective on carotid surgery for patients with a symptomatic and significant carotid stenosis. METHODS AND OUTCOMES: An exploratory semi-structured focus group discussion will be used, as a quality research method. Three groups consisting of 8 patients (n = 24), who underwent the carotid endarterectomy because of a significant and symptomatic stenosis of the internal carotid artery, will be enrolled. If data saturation is not reached, the sample size will be expanded. An expert medical psychologist will lead the focus group discussions. The interviews will be recorded, transcribed 'verbatim' and analyzed after each session. Items valuable to patients regarding their surgery and recovery will be discussed. This protocol will be published prior to the start of the Focus Group Discussion. DISCUSSION: Patients' perspective on outcomes regarding their carotid surgery will be explored and tried to be identified. The results of the focus group discussions may fuel the ongoing global discussion on improving evidence based and patient reported outcome measures and will help the clinical physician to 'understand' their patients better. Focus group discussions may aid in the purpose of verification of PROs and PROMs.

Burnout is not associated with trainee performance on the Vascular Surgery In-Training Exam.

OBJECTIVE: The Vascular Surgery In-Training Examination (VSITE) is a yearly exam evaluating vascular trainees' knowledge base. Although multiple studies have evaluated variables associated with exam outcomes, few have incorporated training program-specific metrics. The purpose of this study is to evaluate the impact of the learning environment and burnout on VSITE performance. METHODS: Data was collected from a confidential, voluntary survey administered after the 2020 to 2022 VSITE as part of the SECOND Trial. VSITE scores were calculated as percent correct then standardized per the American Board of Surgery. Generalized estimating equations with robust standard errors and an independent correlation structure were used to evaluate trainee and program factors associated with exam outcomes. Analyses were further stratified by integrated and independent training paradigms. RESULTS: A total of 1385 trainee responses with burnout data were collected over 3 years (408 in 2020, 459 in 2021, 498 in 2022). On average, 46% of responses reported at least weekly burnout symptoms. On unadjusted analysis, burnout symptoms correlated with a 14 point drop in VSITE score (95% confidence interval [CI], -24 to -4; P = .006). However, burnout was no longer significant after adjusted analysis. Instead, higher postgraduate year level, being in a relationship, identifying as male gender with or without kids, identifying as non-Hispanic white, larger programs, and having a sense of belonging within a program were associated with higher VSITE scores. CONCLUSIONS: Despite high rates of burnout, trainees generally demonstrate resilience in gaining the medical knowledge necessary to pass the VSITE. Performance on standardized exams is associated with trainee and program characteristics, including availability of support systems and program belongingness.

The rise of the machines: are robots the future of renal artery aneurysm repair? A systematic review.

Renal artery aneurysms (RAAs) are a rare vascular condition. Robot-assisted surgery offers a minimally invasive approach for RAA repair, potentially improving surgical outcomes. This review investigates the current evidence on the effectiveness and limitations of this technique. A systematic search following PRISMA guidelines identified relevant studies across five electronic databases. Studies investigating the use of robot-assisted surgery for RAA repair were included. The review identified 11 studies encompassing a total of 23 patients. Procedures included aneurysmectomy, end-to-end anastomosis, prosthetic graft repair, and even coil embolization. All surgeries were successful, with only minor complications reported in four cases. Robot-assisted RAA repair shows promise as a minimally invasive approach with encouraging preliminary outcomes. However, the limited data come from small studies. Future advancements in robotic technology hold the potential to optimize this approach for improved patient care.

Iatrogenic pseudoaneurysm after bone biopsy managed with endovascular coil embolisation.

Bone marrow biopsy (BMB) is a routinely performed procedure, with the preferred site being the posterior superior iliac crest. Uncommonly, it may be complicated by haemorrhagic complications, especially in patients with coagulopathy. Here, we present a case of pelvic haematoma following a BMB due to the injury of the right internal iliac artery. Endovascular embolisation was performed on an urgent basis to manage this complication. The bleeding stopped following the embolisation.

The application and uses of telemedicine in vascular surgery: A narrative review.

Technological advances over the past century have accelerated the pace and breadth of medical and surgical care. From the initial delivery of "telemedicine" over the radio in the 1920s, the delivery of medicine and surgery in the 21st century is no longer limited by connectivity. The COVID-19 pandemic hastened the uptake of telemedicine to ensure that health care can be maintained despite limited face-to-face contact. Like other areas of medicine, vascular surgery has adopted telemedicine, although its role is not well described in the literature. This narrative review explores how telemedicine has been delivered in vascular surgery. Specific themes of telemedicine are outlined with real-world examples, including consultation, triaging, collaboration, mentoring, monitoring and surveillance, mobile health, and education. This review also explores possible future advances in telemedicine and issues around equity of care. Finally, important ethical considerations and limitations related to the applications of telemedicine are outlined.

Large language models and artificial intelligence chatbots in vascular surgery.

Natural language processing is a subfield of artificial intelligence that aims to analyze human oral or written language. The development of large language models has brought innovative perspectives in medicine, including the potential use of chatbots and virtual assistants. Nevertheless, the benefits and pitfalls of such technology need to be carefully evaluated before their use in health care. The aim of this narrative review was to provide an overview of potential applications of large language models and artificial intelligence chatbots in the field of vascular surgery, including clinical practice, research, and education. In light of the results, we discuss current limits and future directions.

Extended and augmented reality in vascular surgery: Opportunities and challenges.

Extended reality has brought new opportunities for medical imaging visualization and analysis. It regroups various subfields, including virtual reality, augmented reality, and mixed reality. Various applications have been proposed for surgical practice, as well as education and training. The aim of this review was to summarize current applications of extended reality and augmented reality in vascular surgery, highlighting potential benefits, pitfalls, limitations, and perspectives on improvement.

Comprehensive review of virtual assistants in vascular surgery.

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.

e-Health and environmental sustainability in vascular surgery.

e-Health technology holds great promise for improving the management of patients with vascular diseases and offers a unique opportunity to mitigate the environmental impact of vascular care, which remains an under-investigated field. The innovative potential of e-Health operates in a complex environment with finite resources. As the expansion of digital health will increase demand for devices, contributing to the environmental burden of electronics and energy use, the sustainability of e-Health technology is of crucial importance, especially in the context of increasing prevalence of cardiovascular diseases. This review discusses the environmental impact of care related to vascular surgery and e-Health innovation, the potential of e-Health technology to mitigate greenhouse gas emissions generated by the health care sector, and to provide leads to research promoting e-Heath technology sustainability. A multifaceted approach, including ethical design, validated eco-audits methodology and reporting standards, technological refinement, electronic and medical devices reuse and recycling, and effective policies is required to provide a sustainable and optimal level of care to vascular patients.

Decreasing Resident Vascular Case Volumes Have Not Changed National Numbers of Vascular Fellowship Applications in US General Surgery Residents Over the Past Twenty Years.

OBJECTIVES: With an aging workforce and high prevalence of vascular disease, the US is expected to face a pronounced shortage of vascular surgeons over the next 2 decades. This has driven initiatives to expand vascular surgery training positions leading to the rise of integrated residency programs (0 + 5) and the expansion of traditional fellowships (VSFs, 5 + 2). Given the increase in dedicated vascular surgery training positions, there has been a growing concern that general surgery residents (GSRs) are experiencing decreased vascular case volumes. We aim to evaluate trends in vascular surgery specialty choice relative to vascular case volumes for US GSRs over the last 20 years. DESIGN: Using the Accreditation Council for Graduate Medical Education (ACGME) Case Log Graduate Statistics National Report, a retrospective analysis of ACGME-accredited GSR vascular case volumes was performed from academic year 1999-2000 to 2021-2022. Fellowship data was retrospectively reviewed using the available National Resident Matching Program (NRMP) Fellowship Match Data & Reports for 2004-2023. RESULTS: Graduating GSRs logged increasing numbers of major cases between AY 1999-2000 and AY 2021-2022 (p < 0.001) with 2022 graduates logging on average 98 more cases per resident compared to 2000 graduates. Mean total vascular cases decreased (p = 0.005) with 2022 graduates logging approximately 78 fewer vascular cases on average compared to the 2000 graduates, a 40% decrease in vascular case volume. Despite the decrease, US GSRs have applied to VSF at a relatively consistent rate: 8.5% in 2001-2002, 8% in 2011-2012, and 6% in 2021-2022. 2023 demonstrated an increase to 8.3%. CONCLUSION: Over the past 2 decades, GSRs have experienced a substantial decrease in exposure to vascular surgery cases during their training; however, residents continue to apply for VSF at a relatively constant rate suggesting that interest in the specialty may be related to factors other than exposure to vascular cases.

Clinical Outcomes of 5000 IU Heparin Versus Activated Clotting Time-Guided Heparinization During Noncardiac Arterial Procedures: A Propensity Score Matched Analysis.

PURPOSE: Previous studies have shown that activated clotting time (ACT)-guided heparinization leads to better anticoagulation levels during noncardiac arterial procedures (NCAP) than a standardized bolus of 5000 IU. Better anticoagulation should potentially result in lower incidence of thrombo-embolic complications (TEC). Comparative investigations on clinical outcomes of these heparinization strategies are scarce. This study investigated clinical outcomes of ACT-guided heparinization with a starting dose of 100 IU/kg in comparison with a single standardized bolus of 5000 IU heparin during NCAP. MATERIALS AND METHODS: Analysis from a prospectively collected database of patients undergoing NCAP in 2 vascular centers was performed. Patients receiving ACT-guided heparinization were matched 1:1 with patients receiving 5000 IU heparin using propensity score matching (PSM). Primary outcomes were TEC, bleeding complications, and mortality within 30 days of procedure or during the same admission. RESULTS: A total of 759 patients (5000 IU heparin: 213 patients, ACT-guided heparinization: 546 patients) were included. Propensity score matching resulted in 209 patients in each treatment group. After PSM, the groups were comparable, with the exception of a higher prevalence of peripheral arterial disease in the ACT-guided heparinization group (103 patients, 49% vs 82 patients, 39%, p=0.039). The target ACT (>200 seconds) was reached in 198 patients (95%) of the ACT-guided group versus 71 patients (34%) of the 5000 IU group (p<0.001), indicating successful execution of the ACT-guided protocol. Incidence of TEC (13 patients, 6.2% vs 10 patients, 4.8%, p=0.52), mortality (3 patients, 1.4% vs 0 patients, p=0.25), and bleeding complications (32 patients, 15% vs 25 patients, 12%, p=0.32) did not differ between patients receiving ACT-guided heparinization and 5000 IU heparin. Protamine was administered in 118 patients (57%) in the ACT group versus 11 patients (5.3%) in the 5000 IU group (p<0.001), but did not influence incidence of TEC (17 patients, 5.9% vs 6 patients, 4.7%, p=0.61) or bleeding complications (34 patients, 12% vs 22 patients, 17%, p=0.14). CONCLUSION: No difference in TEC, bleeding complications, or mortality was found between ACT-guided heparinization and a single bolus of 5000 IU heparin during NCAP. CLINICAL IMPACT: Previous studies have shown that activated clotting time (ACT)-guided heparinization leads to better anticoagulation levels during non-cardiac arterial procedures (NCAP) then a standardized bolus of 5000 IU. Comparative investigations on clinical outcomes are scarce. This study focussed on clinical outcomes of both protocols in NCAP in a propensity score matched cohort. Thrombo-embolic complications (TEC), bleeding complications and mortality within 30 days after NCAP or during the same admission were comparable between groups. Future studies should focus on optimizing ACT-guided protocols, specifically in patients with a high risk of TEC and bleeding complications.

Prehabilitation to Enhance Vascular Surgery Outcomes: A Narrative Review.

Prehabilitation, an emerging strategy, prepares patients for elective surgery by encouraging healthy behaviors, including physical exercise and healthy nutrition, while providing psychological support, to improve postoperative outcomes and foster healthier lifestyles. Despite growing interest, there is little research on prehabilitation. Specifically, studies involving prehabilitation in vascular surgery are heterogeneous with small sample sizes. This review aimed to investigate the reported positive impact of prehabilitation on vascular surgery patients, discuss prehabilitation models, highlight prehabilitation program-associated challenges, and suggest appropriate interventions. Prehabilitation improves physical fitness, reduces postoperative complications, and enhances overall recovery. Multimodal prehabilitation programs can positively impact vascular surgery patients, with benefits including improved cardiovascular fitness, reduced postoperative complications, shorter postoperative hospital stays, enhanced overall recovery, and improved quality of life. The currently reported prehabilitation programs are heterogeneous, with limitations regarding patient adherence and lack of long-term outcomes, posing challenges to their widespread adoption. Overall, prehabilitation shows promise for improving vascular surgery outcomes and fostering long-term healthy behaviors. The systematic implementation of prehabilitation in vascular surgery care pathways, overcoming reported limitations, and integrating multimodal prehabilitation into routine preoperative care hold potential benefits. This review underscores the need for high-quality research to establish best practices in prehabilitation and integrate them into the standard of care for vascular surgery patients.

Collateral circulation in a patient with combined traumatic radial and ulnar artery injuries.

Combined radial and ulnar artery injuries are associated with a >35% amputation rate when not revascularized promptly. We describe a patient who suffered a penetrating injury to both the radial and ulnar arteries. Despite the ulnar artery being ligated and the radial artery primary repair becoming occluded after the index operation, his hand remained salvageable, likely because of collateral arterial pathways. The patient obtained a delayed radial-radial artery bypass and afterward achieved meaningful neuromotor function. This case emphasizes the importance of forearm vascular anatomy variability and the need for prompt management of arterial injuries to reduce limb loss and disability.
