Operative Case Volume for Vascular Integrated Residents and Fellows Following the Elective Surgery Shutdown due to COVID-19.

In response to the COVID-19 pandemic, nonemergent surgery was postponed in efforts to limit disease spread. To determine whether these changes affected vascular integrated resident (VR) and fellow (VF) operative volume, Accreditation Council for Graduate Medical Education (ACGME) case log data was reviewed. Case volume and standard deviation for each major category was for graduates of 2020 and 2021 were compared to the year prior to the pandemic, 2019. There were only 3 significant changes when comparing 2020/2021 to the prepandemic baseline of 2019, with increase in abdominal obstructive cases for VRs (8.1 in 2021 vs 5.9 in 2019, P = .021), an increase in upper extremity cases for VFs (18.9 in 2021 from 15.8 in 2019, P = .029), and a decrease in venous cases for VFs (39.6 in 2021 from 48.4 in 2019, P = .011). Postponing nonemergent surgery did not translate to significant changes in operative cases for graduating VRs and VFs.

Rare Rupture of Small 4.3 cm Abdominal Aortic Aneurysm.

Abdominal aortic aneurysm (AAA) is a common medical condition with the feared, and often fatal, complication of rupture. The risk of rupture has been well documented to correlate with aneurysm size. It is exceedingly rare for an AAA less than 5 cm to rupture. This case report demonstrates an asymptomatic 4.3 cm AAA that ruptured while admitted to the hospital with COVID-19 pneumonia. The patient was successfully managed with an endovascular aortoiliac stent graft. Although rare, in patients with small AAA, rupture must remain in the differential diagnosis in the setting of acute onset abdominal or back pain. Furthermore, when quickly recognized, these patients can be safely managed with an endovascular approach.

A Qualitative Analysis of Physician, Staff, and Patient Perspectives During the Discharge Process for Vascular Patients

Objectives: Evidence demonstrates that when hospitals focus on the discharge process patient safety improves and overall costs decline. Hospital discharge requires care coordination of multiple disciplines, often leading to fragmented care, and adverse outcomes after discharge include emergency department visits and hospital readmissions. The Re-Engineered Discharge (RED) process was developed as an evidence-based strategy to improve the hospital discharge. We evaluated perspectives and priorities of physicians, health care workers, and patients involved in the vascular discharge process using RED as a framework. Method(s): A single-center qualitative analysis using a semi-structured focus groups and an interview guide based on the RED process. Focus groups were Zoom platform recorded, transcribed into text files, independently coded, and analyzed with Dedoose qualitative software using a directed content analysis approach. Thematic concepts were created, and comparisons between groups were analyzed by coding frequency. Researchers independently thematically coded each transcript;prior to analysis, all redundancy of codes was resolved;and all team members agreed on text categorization and coding frequency. Result(s): Eight focus groups with 38 participants were performed. Participants included: physicians (n = 13), nursing and ancillary staff (n = 19), and patients/caregivers (n = 6). Transcript analyses revealed facilitators and barriers to discharge. Overarching themes identified from the qualitative analysis frequencies are displayed by stakeholder role (Fig 1). Themes identified with the greatest coding frequencies included helpfulness of discharge instructions, patient health literacy, patient medical complexity, poor interdisciplinary team communication, time constraints during discharge, technology literacy of patients, barriers to obtaining medications for patients, barriers to organizing outpatient services for health care workers, barriers for patients to obtain help after discharge, and the impact of COVID-19. Conclusion(s): These findings identify the need to strengthen efforts to overcome stakeholder barriers to improve patient safety at the interface of the hospital to create a well-organized discharge. Physicians were most concerned with low patient health literacy, patient understanding of discharge instructions, organizing outpatient services, and overall patient medical complexity hindering a smooth discharge. Health care staff identified time constraints, obtaining medications and, and inter-team communication as their greatest obstacles to an organized discharge. Patients found the complexity and amount of discharge instructions, the impact of COVID-19 on support systems, and technology utilization after discharge most challenging. Modifications to address individual stakeholder barriers within the discharge process are needed to develop a national standardized discharge specific for vascular surgery patients to improve patient safety and satisfaction.

The Effect of the COVID- 19 Outbreak on Intensive Care in Northern Saitama, Japan

Background: The 2020 COVID- 19 pandemic had various effects on local healthcare. The aim of this study was to assess the extent to which local healthcare and healthcare workers were affected by the COVID- 19 pandemic. Method(s): In this observational study we examined and compared intensive care units (ICUs) before (2019) and during (2020) the COVID- 19 pandemic to assess its effects. Emergency patient data were obtained from the Saitama Prefecture Emergency Medical Information System. The effect of COVID- 19 on emergency care responses was compared with the admission and refusal of patients in 2019 and 2020. We also examined the number of patients who were admitted to ICUs and required surgery. The effect on ICUs was examined with the number of Nurses' incident reports and severity percentages calculated from the integrated team medical care and safety system. We also compared the overtime hours of physicians on the basis of employment records. Result(s): In 2019, 2,136 emergency requests were made to admit patients, and 1,811 patients (85%) were admitted. In contrast, in 2020, 2,371 emergency requests were made, and 1,822 patients (76%) were admitted, representing a decrease to 76% (p = 0.931). The percentage of patients for whom admission was refused was significantly greater in 2020 (506 patients, 21.3%) than in 2019 (303 patients, 14.1%;p = 0.0004). In 2020, the number of neurosurgical, cardiac, and vascular operations increased and, over time, the number of operations increased for all surgical units. The number of incidents reported in ICUs increased significantly from 396 in 2019 to 510 in 2020 (p = 0.001). Conclusion(s): Although intensive care management was restricted, the numbers of patients and physician overtime hours were greater during the COVID- 19 pandemic than before, and the resulting environment led to an increase in the number of incidents. The ICU environments must be proactively improved to prepare for more severe situations in the future.Copyright © 2022 Jikei University School of Medicine. All rights reserved.

Surgical clinical characteristics of acute arterial thrombosis of the extremities in the context of SARS-CoV-2 infection

Objective: To determine the clinical-surgical features of critical limb ischaemia (CLI) within the context of infection by SARS-CoV-2. Method(s): Cross-sectional, retrospective, observational, descriptive study, with clinical data obtained from printed and electronic records of patients with CLI treated by the Angiology and Vascular Surgery Service of the General Hospital of Mexico in the period between January 2020 and July 2021. Result(s): We evaluated the data of 33 patients with critical limb ischaemia of which 15 were positive for SARS-CoV-2 in the period from January 2020 to July 2021, females were the most affected representing the 53.3% of the total, patients under 60 years old accounted for 26.67%. Twenty-six percent of the patients presented critical limb ischaemia without having previous comorbidities, 60% of these presented with an advanced state of the disease and a delay in specialised medical care of more than 6 hours after the onset of symptoms, which warranted a major amputation in 37% of cases, the lower extremities represented 90% of the affected anatomical regions. Conclusion(s): the outcomes in our study show that the incidence of critical limb ischaemia during the SARS-CoV2 pandemic period occurred in an atypical way in a segment of young patients and without known event-generating comorbidities. Thromboembolic events, probably associated with the hypercoagulable state generated by this infection, also evolved rapidly and aggressively from the onset of symptoms despite prompt treatment.Copyright © 2022 Sociedad Medica del Hospital General de Mexico.

Vascular Surgery Research in the Coronavirus Disease 2019 Pandemic: A Sex-Based Bibliometric Analysis.

INTRODUCTION: The COVID-19 pandemic has disrupted vascular surgery services globally and its impact on researchers has illustrated disproportionate barriers for female researchers. We assessed the pandemic's consequences on bibliometric trends in vascular surgery and vascular medicine throughout the pandemic. METHODS: A scoping review was performed using the PubMed/MEDLINE, Scopus, and EMBASE databases from January to December 2020 to identify articles related to COVID-19 and vascular surgery or vascular medicine. Articles only describing cardiac or neurovascular care were excluded. The scoping review was performed according to the PRISMA-ScR guidelines. Bibliometric data were extracted and analyzed. RESULTS: Four hundred and fourteen articles were identified, including 125 (30.2%) original articles, 42 (10.1%) review papers, 105 (25.4%) case reports, 27 (6.5%) editorials and commentaries, 94 (22.7%) letters and correspondences, and 21 (5.1%) conference abstracts. The 5 most common countries of study or discussion were all high-income countries. English was the predominant (n = 393, 94.9%) language. Funding was reported for 5.1% (n = 21) of articles. In the first 6 months, 17.6% (n = 30) of first authors and 10.6% (n = 18) of last authors were female, while the last 6 months saw an increase in representation to 30.6% (n = 74) and 15.6% (n = 38) for first and last author, respectively. CONCLUSION: The pandemic caused a rapid surge in vascular publications related to COVID-19. Female authors remain underrepresented in vascular research and the share in female authorship has dropped early in the pandemic, but rose after the end of the first wave. High-income countries remain overrepresented in research productivity, alluding to important disparities in COVID-19-related literature.

Has Lockdown and COVID-19 Led to a Change in the Characteristics of Deep Vein Thrombosis and Patients Who Are Afflicted With It?

BACKGROUND: There is growing evidence identifying coronavirus disease 2019 (COVID-19) as a significant risk factor for thrombosis in inpatients. However, it remains uncertain if patients in the community have been influenced during the COVID-19 pandemic and national lockdown. This study, across four centres in the United Kingdom (UK), reviewed outpatients with deep vein thrombosis (DVT). AIM: This study aims to find out whether lockdown and COVID-19 led to a change in the characteristics of DVT and patients who are afflicted with it, alongside a review of DVT service. METHODS: Data was collected retrospectively from electronic patient records system for the following periods: April 1 to June 30, 2019, and April 1 to June 30, 2020. These were the key months during the first national lockdown in UK. Data were analysed for patient demographics, risk factors, characteristics of DVT, management, and DVT reoccurrence. Statistical analyses were performed using GraphPad Prism 8 (Dotmatics, Boston, Massachusetts, United States). RESULTS: During the study periods, 227 outpatients from the community sustained DVT in 2019 and 211 in 2020. Of these patients, 13 in 2020 were COVID-19 positive. There was a difference in gender distribution with 128 males and 99 females in 2019, and 93 males and 118 females in 2020 (p= 0.0128). No significant difference was noted in the incidence of thrombophilia with nine in 2019 and three in 2020 (p=0.1437). Fewer long-haul journeys were made in 2020 (only two), compared to 16 in 2019 (p=0.012). Fewer patients had immobility as a risk factor in 2020 (n=55) compared to 2019 (n=79) (p=0.0494). However, there were more patients using oral contraceptive pills, with one in 2019 and nine in 2020 (p=0.0086) . CONCLUSION: There is no significant difference in the characteristics, extent, and management of DVT prior to and during the COVID-19 lockdown. National lockdowns do not affect DVT in the community; however, it is important to highlight the surrounding inpatient numbers.

NAD+ Biosynthesis Impairment and Acute Kidney Injury after Major Vascular Surgery.

Acute kidney injury (AKI) is a serious complication after vascular surgery. Reduced synthesis of nicotinamide adenine dinucleotide (NAD+) from tryptophan is associated with an increased risk of AKI in critically ill patients, patients hospitalized with COVID-19, and cardiac surgery patients, and is marked by elevated urinary quinolinate and quinolinate to tryptophan ratios. We measured quinolinate concentrations in vascular surgery patients to determine if impaired NAD+ synthesis was associated with AKI in this patient population. Eight preoperative and eight postoperative vascular surgery patients who developed AKI were selected from a parent study to participate in this single-center case-control study. They were matched with controls who did not develop AKI based on age, sex, BMI, eGFR, hypertension, and diabetes. Urinary quinolinate and tryptophan concentrations were measured at anesthetic induction and on postoperative day one. Two-sided Mann-Whitney U tests were used to compare quinolinate and quinolinate to tryptophan ratios. Multivariate linear regression modeling was used to estimate the relationship between quinolinate and serum creatinine. There was no difference in preoperative or postoperative urine quinolinate concentrations or the preoperative quinolinate to tryptophan ratio between patients that did and did not develop AKI (p = 0.07, 0.50, and 0.32, respectively). However, postoperative quinolinate to tryptophan ratios were higher in AKI patients (p = 0.04). Further, after adjustment for AKI risk factors, higher preoperative quinolinate concentrations and higher postoperative quinolinate to tryptophan ratios were associated with greater postoperative creatinine increases (p = 0.04 and 0.04, respectively). These data suggest that impaired NAD+ synthesis may contribute to AKI development in vascular surgery patients.

Variant of subclavian steal syndrome: unusual anatomical relationship between left subclavian artery and left vertebral artery.

A woman in her 70s presented to her general practitioner (GP) with a 3-month history of left upper arm pain and weakness. A significant difference in bilateral blood pressures was noted and a further history elicited coolness in her left arm without functional compromise. A CT angiography revealed variant subclavian steal syndrome with a subclavian arterial stenosis, which was proximal to both the internal mammary and thyrocervical trunk and her left vertebral artery originating from the aortic arch. She was referred to a vascular surgeon but declined surgical intervention. Her symptoms remain stable with 6-month follow-up from her GP. This case highlights the importance of considering vascular aetiologies in upper limb pain and weakness. Our case reviews the differential diagnoses of upper limb pain and weakness, consequently leading to the discussion of an interesting variant of subclavian stenosis.

Application of Neoaortoiliac System For Contained Rupture of Mycotic Infrarenal Aortic Aneurysm

Funding: None. Synopsis: 61-year-old male who initially presented to an outside facility with streptococcal pneumoniae meningitis and bacteremia. Of note, he had history of COVID-19 pneumonia a month prior. On hospital day 15, he reported sudden onset lower back pain prompting imaging which demonstrated a contained rupture of an infrarenal aortic aneurysm that had significantly evolved in comparison to admission imaging where his infrarenal aorta had the largest dimension measuring 2.9cm. We present the successful application of neoaortoiliac system (NAIS). Method(s): Proceeding with midline laparotomy we encountered dense adhesive disease due to his history of surgery for colon cancer. After adhesiolysis, we exposed the aorta and aneurysm with severe surrounding inflammatory changes. 20cm of femoral vein was harvested, reversed, and joined for a span of 4cm using an Endo GIA 45mm vascular load to create our neoaorta. Proximal and distal clamp zones were developed. Upon entering the aneurysm, a foul smell was encountered, revealing that the noxious process had destroyed the posterior wall of the aorta and paraspinal tissues. Our neoaorta was anastomosed in end-to-end fashion to the infrarenal aorta and subsequently to the common iliac arteries. Flow was initially restored to the hypogastric arteries and then the external iliac arteries. The retroperitoneum was closed over our repair and covered with omentum. Result(s): On post-operative day 2, he had hematochezia;intraoperatively, the IMA was noted to be 1mm in size, though had brisk back-bleeding and was ultimately ligated. A flexible sigmoidoscopy revealed ischemic sloughing of the sigmoid colon near his previous anastomosis from his colon cancer resection though no transmural necrosis. He remains on high-dose ceftriaxone to complete a 6-week course and metronidazole for 10 days due to his sigmoid mucosal ischemia per infectious disease recommendations. He is now post-operative day 10 and remains in the ICU. Conclusion(s): Mycotic aortic aneurysms constitute 1-1.8% of aortic aneurysms. The standard of treatment is aggressive debridement of involved aortic wall and periaortic tissue, in-situ or extra-anatomic reconstruction, coverage with an omental flap and long-term antibiotic therapy. NAIS is resistant to infection and aneurysmal dilation, however, is a time-consuming procedure with a mean completion time of 8 hours. Dorweiler et al. demonstrated that vascular reconstruction with femoral vein in infected aortoiliofemoral fields has a mortality of 9-10% with negligible rate of late complications (graft stenosis, thrombosis, and dilation) and that venous morbidity after femoral vein harvest is well tolerated. Clagett et al. demonstrated that NAIS fashioned from greater saphenous vein had a failure rate requiring intervention of 64% compared to 0% for those constructed with deep femoral vein. Lastly, it is important to note that our patient was previously COVID-19 positive. This case demonstrates that the sequela of COVID-19 may have been a significant factor in our patient's pathophysiology. As we continue to learn about the effects of COVID-19 on vascular pathology, we must keep a large repertoire of operative techniques at hand in order to treat complex presentations of vascular emergencies.

RESULTS of ACTIVITIES of the DEPARTMENT of VASCULAR SURGERY AMIDST COVID-19 PANDEMIC.

Aim To conduct comparative analysis of the activities of the department of vascular surgery before and during the spread of new coronavirus infection COVID-19 (SARS-CoV-2). Methods The analysis was performed on the number of outpatient visits of vascular surgeon for types of diagnosis, number and type of surgeries performed at the inpatient facilities of the LLC "Grand Medica" over 2019 (whole year) and 2020 (quarterly). Results Significant decrease was noted in the number of visits of patients with cardiovascular diseases to vascular surgeon in the outpatient facility. The number of surgeries on limb arteries in patients among Kuzbass residents decreased by 26.4 %, among residents of other regions - by 59.5 %;in brachiocephalic arteries - by 12.5 % and 54.5 %, respectively. The number of percutaneous transluminal coronary angioplasty (PTCA) in patients among Kuzbass residents increased by 25.3 %, among residents of other regions remained unchanged. Conclusion Decrease in the volume of provision of care for patients with cardiovascular diseases over 2-4 quarters of 2020 is caused by two groups of factors. The first one is associated directly to the epidemiological situation and countermeasures against the spread of SARS-CoV-2 while the second one is associated indirectly.Copyright © 2021 Russian Academy of Sciences.

Utilizing Mobile Diabetic Foot Clinics To Provide Comprehensive Care To Patients Experiencing Homelessness

Introduction and Objectives: Limited healthcare access and resource inequities pose significant barriers to care, all of which have been amplified during the COVID-19 pandemic. DFUs represent an especially challenging medical problem to prevent and treat due to the resource intensive care required. We sought to evaluate the feasibility of multidisciplinary, mobile, DFU outreach clinics to improve access to care. Method(s): Our clinic model focused on creating mobile diabetic foot clinics staffed by volunteer clinical providers who specialize in Vascular Surgery, Diabetes, and Podiatry. We recruited volunteer healthcare providers from an academic medical center. We partnered with local community centers with established programs providing services to unhoused individuals. Result(s): Between June 2020 and August 2022, a total of 130 unhoused individuals were seen at four mobile clinics set up at different locations. Diabetic foot care was provided by volunteers from seven departments: Endocrinology/Diabetes, Vascular Surgery and Vascular Lab, Podiatry, Addiction Medicine, Smoking Cessation, and Financial. On average, 32 healthcare provider volunteers participated at each clinic. Services provided include: vitals, blood glucose, HgA1c, lipid panel testing, ankle-brachial index, podiatric exam, wound care, medical education, COVID vaccination/booster, insurance enrollment, and new socks and shoes. Of 130 unhoused patients, 29% had hypertension (38), 34% had abnormal ABI (44), and 14% had diabetes (18). Fifteen patients were further identified as high risk for developing DFU-associated amputation (12%) and were provided with ambulatory follow-ups. Conclusion(s): In our pilot experience, it is feasible to provide consistent comprehensive DFU care through mobile outreach clinics. By using the infrastructure of partner organizations and healthcare expertise of an academic center, our clinics could integrate into existing community services. [Formula presented]Copyright © 2022

Impact of COVID-19 on key performance indicators: analysis of diagnosis related groups in a vascular surgery department.

Objectives: to evaluate the impact of the COVID-19 on the hospital key performance indicators using the diagnosis-related groups (DRG). To compare the results of the Angiology and Vascular Surgery Department of the University Hospital of Cabuenes (HUCAB) with the database of the Ministry of Health. Material(s) and Method(s): hospital discharges from the Vascular Surgery Department of the HUCAB during the years 2019, 2020 and 2021. All patients refined (APR)-DRG system was extracted for discharge coding. The hospital key indicators studied were: number of discharges, mortality, mean stay (EM) and mean weight (PM) of the DRG. The overall results per year and according to the most prevalent DRGs were studied. The results obtained were compared with the annual data from the coding of the Minimum Basic Data Set (CMBD) of the Ministry of Health. The configured EM by adjusting the performance of the standard (EMAF) and by the casuistry (EMAC), the index of the adjusted EM (IEMA), the functional index (FI), casuistic index (CI) and the number of avoidable hospital stays were also analyzed. Result(s): number of discharges: it was 10 % inferior in 2020 compared to 2019. Discharges of the GRD 181 linked to admissions from the Emergency increased more than 50 % during 2020 and more than 100 % in 2021 compared to 2019. Mortality: there was no significant increase. EM: it decreased 20 % in 2020 and 18 % in 2021, compared to 2019. PM: it increased progressively to 7.7% on average in 2021. EMAF: it was superior to standard EM. The number of stays saved was higher than expected. Conclusion(s): the pandemic of COVID-19 influenced the hospital key performance indicators studied, reducing the number of discharges and ME and increasing the PM of the DRGs. The number of avoidable stays saved was greater than the standard.© Copyright 2023 SEACV.

Telemedicine at the VA: Examining smartphone connectivity rates to VA video connect and doximity dialer video.

Background: Telemedicine usage has accelerated as a result of the COVID-19 pandemic, raising concerns those without the necessary technology and digital literacy to participate may face increasing health disparities. In this study, we examined the rates at which veterans are able to connect to two common telemedicine applications: VA Video Connect (VVC) and Doximity Dialer Video (DV). Methods: Participants were selected from a pool of vascular surgery patients seen from August 2020 to October 2021 at a single Veterans Affairs medical center. Participants had to be >50 years old and not previously participated in a video visit. Eligible veterans were asked their interest participating in video visits and if they owned a smartphone. Those who met the eligibility requirements were tested on their ability to connect to both VVC and DV with minimal assistance. The connectivity rate for both platforms was recorded, and basic demographic and medical history information was collected. Results: One-hundred-four veterans participated in the study, with an average age of 70 ± 7 years. Seventy-four participants (71%) expressed interest in video visits, and 52 (70%) owned a smartphone. Forty-five smartphone owners (87%) successfully connected to DV, whereas 19 (37%) successfully connected to VVC (p < 0.001). VVC connectivity decreased with increasing age-group: 50-59 = 80%, 60-69 = 44%, ≥70 = 18% (p = 0.02). Conclusions: Older veterans demonstrate difficulty connecting to VVC. The VHA is taking important steps to streamline usability of VVC, however continued expansion of support programs is necessary to improve access and reduce healthcare disparities in this population.

Racial diversity and Black vascular surgeons in vascular surgery workforce.

OBJECTIVES: The precise number of actively practicing vascular surgeons who self-identify as Black American and the historical race composition trends within the overall profession of vascular surgery are unknown. Limited demographic data have been collected and maintained at the societal or national board level. Vascular surgery societal reports suggest that less than 2% of vascular surgeons identify as Black American. Black Americans comprise 13.4% of the U.S. population yet for disorders such as peripheral artery disease and end-stage renal disease, Black communities are disproportionately impacted, and the prevalence of disease is greater on an age-adjusted basis. A significant body of research shows that clinical outcomes such as medication adherence, shared decision-making, and research trial participation are positively impacted by racial concordance especially for communities in whom distrust is high as a consequence of historic experiences. This survey aims to characterize practice and career variables within a network of Black American vascular surgeons. METHODS: A cross-sectional survey was conducted via a questionnaire sent to all participants of the Society of Black Vascular Surgeons that began to convene monthly during the COVID-19 pandemic and experienced subsequent organic growth. The survey included 20 questions with variables quantified including the surgeon's demographics, clinical experience, practice setting, patient demographics, and professional society engagement. RESULTS: Fifty-nine percent of the Society of Black Vascular Surgeons members completed the survey. Males comprised 81% of the responding vascular surgeons. The majority (62%) of respondents were involved in academic practice. Less than 25% of the total medical staff were Black American in 77% of the respondents' current work practice. The patient racial composition within their respective practice settings was as follows: White (47%), Black (34%), Hispanic (13%), Asian (3%), Middle Eastern or North African (2%), and American Indian and Alaskan Natives (0.4%). Forty-three percent of respondents had a current active membership in the Society for Vascular Surgery, and 24% had a regional society membership. Fifty-eight percent of respondents reported that they experienced a workplace event that they felt was racially or ethically driven in the 12 months before the survey. CONCLUSIONS: This survey describes an under-represented in medicine vascular surgeon subgroup that has not heretofore been characterized. Racial and ethnic demographic data are essential to better understand the current demographic makeup of our specialty and to develop benchmark goals of race composition that mirrors our society at large. The patients of this group of Black American vascular surgeons were more likely to represent a racial minority. Efforts to increase race diversity in vascular surgery have the potential benefit of enhancing care of patients with vascular disease.

Editor's Choice - Outcomes of Surgery for Patients with Peripheral Arterial Disease During the COVID-19 Pandemic in the United Kingdom: A Population Based Study.

OBJECTIVE: There is limited information on changes in the patterns of care and outcomes for patients who had vascular procedures after the first wave of the COVID-19 pandemic. The aim of this population based study was to examine the patterns of care and outcomes for vascular lower limb procedures in the UK during the COVID-19 pandemic. METHODS: Lower limb revascularisations and major amputations performed from January 2019 to April 2021 in the UK and entered in the National Vascular Registry were included in the study. The primary outcome was in hospital post-operative death and secondary outcomes were complications and re-interventions. The study was divided into Pre-pandemic (1 January 2019 - 29 February 2020), Wave 1 (1 March - 30 June 2020), Respite (1 July - 31 October 2020), Wave 2/3 (1 November 2020 - 30 April 2021). RESULTS: The study included 36 938 procedures (7 245 major amputations, 16 712 endovascular, 12 981 open revascularisations), with 15 501 procedures after March 2020, a 27.7% reduction compared with pre-pandemic. The proportion of open surgical procedures performed under general anaesthetic was lower in Wave 1 and after compared with pre-pandemic (76.7% vs. 81.9%, p < .001). Only 4.6% of patients in the cohort had SARS-CoV-2 infection (n = 708), but their in hospital post-operative mortality rate was 25.0% (n = 177), six times higher than patients without SARS-CoV-2 (adjusted odds ratio 5.88; 95% CI 4.80 - 7.21, p < .001). The in hospital mortality rate was higher during the pandemic than pre-pandemic after elective open and endovascular revascularisation (respectively 1.6% vs. 1.1%, p = .033, and 0.9% vs. 0.5%, p = .005) and after major amputations (10.4% during Wave 2/3 vs. 7.7% pre-pandemic, p = .022). CONCLUSION: There was excess post-operative mortality rate for patients undergoing lower limb vascular procedures during the pandemic, which was associated with SARS-CoV-2 infections. Further research should be conducted on long term outcomes of patients operated on during the COVID-19 pandemic period.

Virtual vascular surgery interest group during the coronavirus disease 2019 pandemic.

OBJECTIVES: Early exposure to vascular surgery at the medical student level positively influences one's decision to apply into an integrated vascular surgery residency program. Vascular surgery interest groups (VSIGs) are student-run and aim to facilitate such exposure, traditionally via in-person events. Social distancing during the coronavirus disease 2019 pandemic disrupted these interactions. This is a description of the virtual activities of a VSIG group during the 2020-2021 academic year and highlights their impact among medical students. METHODS: The virtual activities of the VSIG at the Yale School of Medicine were reviewed. Students received surveys prior and after activities to assess their impact. Preactivity and postactivity surveys using Likert scale (1 = completely disagree; 5 = completely agree) were administered and compared. Statistical significance was achieved with a P value of less than .05. RESULTS: A total of five virtual events were held: an Introductory Session (October 2020), a Simulation Session (November 2020), a Research Night (January 2021), a Journal Club (February 2021), and a National Match Panel (April 2021). The surveys of three events (Introductory Session, Simulation Session, and National Match Panel) were analyzed. Attendance at these events were 18, 55, and 103 respectively. The average presurvey response rate was 51.2% and the average postsurvey response rate was 27.46%. Students agreed that the Introductory Session increased their knowledge about vascular surgery as a subspecialty (4.22 ± 0.67) and that the session was valuable to their time (4.33 ± 1.00). The Simulation Session increased student's comfort with knot tying from 1.73 ± 0.89 to 3.21 ± 1.25 (P < .001). Students reported an increased understanding of residency program selection (2.39 ± 1.10 vs 3.21 ± 1.12; P = .018), the Electronic Residency Application Service application (2.16 ± 1.01 vs 3.00 ± 0.88; P = .007), and letters of recommendation (2.45 ± 1.07 vs 3.14 ± 1.17; P = .04). Students particularly had a significant increase in the understanding of the logistics of residency interviews, which were held virtually that year for the first time (1.84 ± 0.96 vs 3.29 ± 1.20; P < .001). CONCLUSIONS: Virtual VSIG activities were feasible and effective during the pandemic in promoting student engagement and interest in vascular surgery. Despite lifting social distancing measures, the virtual format could become a valuable tool to expand outreach efforts of the vascular surgery community to recruit talented medical students.

Anaesthesia for vascular emergencies - a state of the art review.

In this state-of-the-art review, we discuss the presenting symptoms and management strategies for vascular emergencies. Although vascular emergencies are best treated at a vascular surgical centre, patients may present to any emergency department and may require both immediate management and safe transport to a vascular centre. We describe the surgical and anaesthetic considerations for management of aortic dissection, aortic rupture, carotid endarterectomy, acute limb ischaemia and mesenteric ischaemia. Important issues to consider in aortic dissection are extent of the dissection and surgical need for bypasses in addition to endovascular repair. From an anaesthetist's perspective, aortic dissection requires infrastructure for massive transfusion, smooth management should an endovascular procedure require conversion to an open procedure, haemodynamic manipulation during stent deployment and prevention of spinal cord ischaemia. Principles in management of aortic rupture, whether open or endovascular treatment is chosen, include immediate transfer to a vascular care centre; minimising haemodynamic changes to reduce aortic shear stress; permissive hypotension in the pre-operative period; and initiation of massive transfusion protocol. Carotid endarterectomy for carotid stenosis is managed with general or regional techniques, and anaesthetists must be prepared to manage haemodynamic, neurological and airway issues peri-operatively. Acute limb ischaemia is a result of embolism, thrombosis, dissection or trauma, and may be treated with open repair or embolectomy, under either general or local anaesthesia. Due to hypercoagulability, there may be higher numbers of acutely ischaemic limbs among patients with COVID-19, which is important to consider in the current pandemic. Mesenteric ischaemia is a rare vascular emergency, but it is challenging to diagnose and associated with high morbidity and mortality. Several peri-operative issues are common to all vascular emergencies: acute renal injury; management of transfusion; need for heparinisation and reversal; and challenging postoperative care. Finally, the important development of endovascular techniques for repair in many vascular emergencies has improved care, and the availability of transoesophageal echocardiography has improved monitoring as well as aids in surgical placement of endovascular grafts and for post-procedural evaluation.

Narrative Review of New Insight into the Influence of the COVID-19 Pandemic on Cardiovascular Care.

Background and Objectives: The purpose of this paper was to perform a literature review on the effects of the COVID-19 pandemic on cardiothoracic and vascular surgery care and departments. Materials and Methods: To conduct this evaluation, an electronic search of many databases was conducted, and the resulting papers were chosen and evaluated. Results: Firstly, we have addressed the impact of COVID-19 infection on the cardiovascular system from the pathophysiological and treatment points of view. Afterwards, we analyzed every cardiovascular disease that seemed to appear after a COVID-19 infection, emphasizing the treatment. In addition, we have analyzed the impact of the pandemic on the cardiothoracic and vascular departments in different countries and the transitions that appeared. Finally, we discussed the implications of the cardiothoracic and vascular specialists' and residents' work and studies on the pandemic. Conclusions: The global pandemic caused by SARS-CoV-2 compelled the vascular profession to review the treatment of certain vascular illnesses and find solutions to address the vascular consequences of COVID-19 infection. The collaboration between vascular surgeons, public health specialists, and epidemiologists must continue to investigate the impact of the pandemic and the response to the public health issue.
