Ann Vasc Surg 2024; 106:227-237. [PMID: 38815913 DOI: 10.1016/j.avsg.2024.04.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 03/25/2024] [Accepted: 04/09/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND The frequency of distal lower extremity bypass (LEB) for infrapopliteal critical limb threatening ischemia (IP-CLTI) has significantly decreased. Our goal was to analyze the contemporary outcomes and factors associated with failure of LEB to para-malleolar and pedal targets. METHODS We queried the Vascular Quality Initiative infrainguinal database from 2003 to 2021 to identify LEB to para-malleolar or pedal/plantar targets. Primary outcomes were graft patency, major adverse limb events [vascular reintervention, above ankle amputation] (MALE), and amputation-free survival at 2 years. Standard statistical methods were utilized. RESULTS We identified 2331 LEB procedures (1,265 anterior tibial at ankle/dorsalis pedis, 783 posterior tibial at ankle, 283 tarsal/plantar). The prevalence of LEB bypasses to distal targets has significantly decreased from 13.37% of all LEB procedures in 2003-3.51% in 2021 (P < 0.001). The majority of cases presented with tissue loss (81.25. Common postoperative complications included major adverse cardiac events (8.9%) and surgical site infections (3.6%). Major amputations occurred in 16.8% of patients at 1 year. Postoperative mortality at 1 year was 10%. On unadjusted Kaplan-Meier survival analysis at 2 years, primary patency was 50.56% ± 3.6%, MALE was 63.49% ± 3.27%, and amputation-free survival was 71.71% ± 0.98%. In adjusted analyses [adjusted for comorbidities, indication, conduit type, urgency, prior vascular interventions, graft inflow vessel (femoral/popliteal), concomitant inflow procedures, surgeon and center volume] conduits other than great saphenous vein (P < 0.001) were associated with loss of primary patency and increased MALE. High center volume (>5 procedures/year) was associated with improved primary patency (P = 0.015), and lower MALE (P = 0.021) at 2 years. CONCLUSIONS Despite decreased utilization, open surgical bypass to distal targets at the ankle remains a viable option for treatment of IP-CLTI with acceptable patency and amputation-free survival rates at 2 years. Bypasses to distal targets should be performed at high volume centers to optimize graft patency and limb salvage and minimize reinterventions.

Implementation of 3D modelling to improve understanding and conceptualisation of arteriovenous malformation (AVM) morphology for the execution of safe microsurgical excision of complex paediatric AVMs. Childs Nerv Syst 2024; 40:2431-2442. [PMID: 38662221 DOI: 10.1007/s00381-024-06421-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 04/17/2024] [Indexed: 04/26/2024]
Abstract
INTRODUCTION Brain arteriovenous malformations (bAVMs) present complex challenges in neurosurgery, requiring precise pre-surgical planning. In this context, 3D printing technology has emerged as a promising tool to aid in understanding bAVM morphology and enhance surgical outcomes, particularly in pediatric patients. This study aims to assess the feasibility and effectiveness of using 3D AVM models in pediatric bAVM surgery. METHODOLOGY The study was conducted at Great Ormond Street Hospital, and cases were selected sequentially between October 2021 and February 2023. Eight pediatric bAVM cases with 3D models were compared to eight cases treated before the introduction of 3D printing models. The 3D modelling fidelity and clinical outcomes were assessed and compared between the two cohorts. RESULTS The study demonstrated excellent fidelity between 3D models and actual operative anatomy, with a median difference of only 0.31 mm. There was no statistically significant difference in angiographic cure rates or complications between the 3D model group and the non-3D model group. Surgical time showed a non-significant increase in cases involving 3D models. Furthermore, the 3D model cohort included higher-grade bAVMs, indicating increased surgical confidence. CONCLUSION This study demonstrates the feasibility and efficacy of utilizing 3D AVM models in pediatric bAVM surgery. The high fidelity between the models and actual operative anatomy suggests that 3D modelling can enhance pre-surgical planning and intraoperative guidance without significantly increasing surgical times or complications. Further research with larger cohorts is warranted to confirm and refine the application of 3D modelling in clinical practice.

[PMID: 38122970 DOI: 10.1016/j.avsg.2023.10.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 10/13/2023] [Accepted: 10/16/2023] [Indexed: 12/23/2023]
Abstract
BACKGROUND Comprehensive vascular care includes both arterial and venous disease management. However, operative training in venous disease is often significantly overshadowed by arterial procedures, despite the public health burden of acute and chronic venous disease. The purpose of this study is to evaluate the case-mix and volume of venous procedures performed by graduating integrated vascular surgery residents and fellows in the United States. METHODS Accreditation Council for Graduate Medical Education national operative log reports were compiled for graduating integrated VSR (vascular surgery residency) and traditional vascular surgery fellowship (VSF) trainees from academic years 2013 to 2022. Only cases categorized as "surgeon fellow", "surgeon chief", or "surgeon junior" were included. Linear regression analysis was utilized to evaluate trends in case-mix and volume. RESULTS Over the 10-year study period, total vascular cases increased for both VSR (mean 870.5 ± 9.3 cases, annual change +9.5 cases/year, R2 = 0.77, P < 0.001) and VSF (mean 682.1 ± 6.9 cases, annual change +6.7 cases/year, R2 = 0.85, P < 0.001) trainees. Concurrently, the proportion of venous cases in the VSR group decreased from 12.5% to 7.3% (annual change -3.7 cases/year, R2 = 0.72, P < 0.001). VSR trainees experienced an annual decrease in 4 of the top 5 venous case types performed, including venous angioplasty/stenting (-1.6 cases/year, P = 0.002), vena cava filter placement (-0.9 cases/year, P = 0.002), endoluminal ablation (-0.2 cases/year, P = 0.47), diagnostic venography (-1.7 cases/year, P < 0.001), and varicose vein treatment (-1.0 cases/year, P < 0.001). Venous cases proportions also decreased in the VSF group from 8.4% to 6.2% (annual change -2.2 cases/year, R2 = 0.54, P = 0.002). VSF trainees experienced an annual decrease in 4 of the top 5 venous case types, including venous angioplasty/stenting (-1.5 cases/year, P = 0.003), diagnostic venography (-1.2 cases/year, P < 0.001), vena cava filter placement (-0.2 cases/year, P = 0.44), endoluminal ablation (-0.6 cases/year, P < 0.001), and varicose vein treatment (-0.1 cases/year, P = 0.04). Both VSR and VSF trainee groups graduated with fewer than 5 cases for each of the following venous procedures-percutaneous mechanical thrombectomy, venous thrombolysis, open venous reconstruction, sclerotherapy, venous embolectomy, portal-systemic shunting, venous ulceration treatment, and arteriovenous malformation treatment. CONCLUSIONS Current vascular residents and fellows have limited exposure to venous procedures, in part due to a proportional decline in venous cases. More robust venous operative experience is needed during surgical training. Further studies are needed to understand whether this discrepancy in venous and arterial training impacts career progression and patient outcomes.

[PMID: 38414727 PMCID: PMC10897809 DOI: 10.1016/j.ejvsvf.2024.01.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2023] [Revised: 11/03/2023] [Accepted: 01/23/2024] [Indexed: 02/29/2024] Open
Abstract
Objective Due to its video based approach, YouTube has become a widely accessed educational resource for patients and trainees. This systematic review characterised and evaluated the peer reviewed literature investigating YouTube as a source of patient or trainee education in vascular surgery. Data sources A comprehensive literature search was conducted using EMBASE, MEDLINE, and Ovid HealthStar from inception until 19 January 2023. All primary studies and conference abstracts evaluating YouTube as a source of vascular surgery education were included. Review methods Video educational quality was analysed across several factors, including pathology, video audience, and length. Results Overall, 24 studies were identified examining 3 221 videos with 123.1 hours of content and 37.1 million views. Studies primarily examined YouTube videos on diabetic foot care (7/24, 29%), peripheral arterial disease (3/24, 13%), carotid artery stenosis (3/24, 13%), varicose veins (3/24, 13%), and abdominal aortic aneurysm (2/24, 8%). Video educational quality was analysed using standardised assessment tools, author generated scoring systems, or global author reported assessment of quality. Six studies assessed videos for trainee education, while 18 studies evaluated videos for patient education. Among the 20 studies which reported on the overall quality of educational content, 10/20 studies deemed it poor, and 10/20 studies considered it fair, with 53% of studies noting poor educational quality for videos intended for patients and 40% of studies noting poor educational quality in videos intended for trainees. Poor quality videos had more views than fair quality videos (mean 27 348, 95% CI 15 154-39 543 views vs. 11 372, 95% CI 3 115-19 629 views, p = .030). Conclusion The overall educational quality of YouTube videos for vascular surgery patient and trainee education is suboptimal. There is significant heterogeneity in the quality assessment tools used in their evaluation. A standardised approach to online education with a consistent quality assessment tool is required to better support online patient and trainee education in vascular surgery.

J Vasc Surg 2023; 78:1541-1547. [PMID: 37558145 DOI: 10.1016/j.jvs.2023.07.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 07/25/2023] [Accepted: 07/29/2023] [Indexed: 08/11/2023]
Abstract
BACKGROUND Endovascular and hybrid interventions have played an increasingly prominent role in the treatment of peripheral arterial disease (PAD) in the past decade. This shift has prompted concerns about the adequacy of open surgical training for current surgical residents. Moreover, the recent Best Surgical Therapy in Patients With Critical Limb Ischemia trial has further emphasized the importance of open surgical techniques in the treatment of peripheral arterial disease. The purpose of this study was to examine national temporal trends in peripheral operative volume among integrated vascular surgery residents. METHODS Data was obtained from the Accreditation Council for Graduate Medical Education national data reports for integrated vascular surgery residents. Case volumes for surgeon chief or surgeon junior cases were collected from academic years 2012 to 2013 and 2021 to 2022. Trends in case-mix and volume were evaluated using linear regression analysis. RESULTS The mean total vascular operative volume increased from 851.2 to 914.3 cases among graduating chief residents, with an annual growth of 8.5 ± 1.7 cases/year (R2 = 0.77; P < .0001). Major vascular case volume also increased at a rate of 5.7 ± 1.2 cases/year (R2 = 0.74; P < .001). Among operative categories, peripheral cases were the most frequent (n = 232.2 [26.6%]) and demonstrated the greatest annual growth (+8.0 ± 0.8 cases/year, R2 = 0.93; P < .001). No changes were seen in volume of open peripheral cases, including suprainguinal bypass (+0.1 ± 0.2 cases/year; R2 = 0.08; P = .40) or femoropopliteal bypass procedures (-0.1 ± 0.2 cases/year; R2 = 0.17; P = .20). Infrapopliteal bypass (+0.4 ± 0.1 cases/year; R2 = 0.48; P = .006), iliac/femoral endarterectomy (+1.3 ± 0.2 cases/year; R2 = 0.82; P < .001), and leg thromboembolectomy (+0.4 ± 0.1 cases/year; R2 = 0.64; P < .001) all demonstrated annual growth. For endovascular peripheral cases, aortoiliac revascularization (+3.4 ± 0.3 cases/year; R2 = 0.94; P < .001), femoropopliteal revascularization (+5.4 ± 0.2 cases/year; R2 = 0.98; P < .001), and tibioperoneal revascularization (+2.0 ± 0.2 cases/year; R2 = 0.92; P < .001) all increased in volume. Lower extremity amputations, including above-knee amputation (+0.6 ± 0.2 cases/year; R2 = 0.65; P < .001) and below-knee amputation (+0.9 ± 0.2 cases/year; R2 = 0.72; P < .001) also demonstrated an increase in volume. CONCLUSIONS Current graduating residents have higher open and endovascular case volumes for peripheral artery disease on a national level, despite the increasing popularity of endovascular techniques. Further studies are needed to identify how these trends may impact current vascular surgery milestones. These trends may also influence the rising interest in competency-based training programs.
