An international, multispecialty, expert-based Delphi Consensus document on controversial issues in the management of patients with asymptomatic and symptomatic carotid stenosis. J Vasc Surg 2024; 79:420-435.e1. [PMID: 37944771 DOI: 10.1016/j.jvs.2023.09.031] [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: 08/22/2023] [Revised: 09/25/2023] [Accepted: 09/25/2023] [Indexed: 11/12/2023]
Abstract
OBJECTIVE Despite the publication of various national/international guidelines, several questions concerning the management of patients with asymptomatic (AsxCS) and symptomatic (SxCS) carotid stenosis remain unanswered. The aim of this international, multi-specialty, expert-based Delphi Consensus document was to address these issues to help clinicians make decisions when guidelines are unclear. METHODS Fourteen controversial topics were identified. A three-round Delphi Consensus process was performed including 61 experts. The aim of Round 1 was to investigate the differing views and opinions regarding these unresolved topics. In Round 2, clarifications were asked from each participant. In Round 3, the questionnaire was resent to all participants for their final vote. Consensus was reached when ≥75% of experts agreed on a specific response. RESULTS Most experts agreed that: (1) the current periprocedural/in-hospital stroke/death thresholds for performing a carotid intervention should be lowered from 6% to 4% in patients with SxCS and from 3% to 2% in patients with AsxCS; (2) the time threshold for a patient being considered "recently symptomatic" should be reduced from the current definition of "6 months" to 3 months or less; (3) 80% to 99% AsxCS carries a higher risk of stroke compared with 60% to 79% AsxCS; (4) factors beyond the grade of stenosis and symptoms should be added to the indications for revascularization in AsxCS patients (eg, plaque features of vulnerability and silent infarctions on brain computed tomography scans); and (5) shunting should be used selectively, rather than always or never. Consensus could not be reached on the remaining topics due to conflicting, inadequate, or controversial evidence. CONCLUSIONS The present international, multi-specialty expert-based Delphi Consensus document attempted to provide responses to several unanswered/unresolved issues. However, consensus could not be achieved on some topics, highlighting areas requiring future research.

Abstract
Acute deep venous thrombosis (DVT) is a common health problem, affecting millions of patients in Europe and the United States annually. Europe and US national clinical practice guidelines are formulated by evaluation of the available scientific evidence, with expert opinion to create pragmatic guidance for the optimal patient management, representing the best available knowledge at the time of publication, and providing the best evidence-based recommendations for vascular patient care and venous pathologies. We here focus on the novel recommendations proposed by European and US guidelines for acute DVT, denoting main differences between the two panels. This review gives vascular surgeons the opportunity to identify the key points of the two largest Vascular Committees guidelines, in order to use them and offer their best individualized treatment approach to the specific patient's anatomy, lesion, and history.

Carotid Plaque-RADS: A Novel Stroke Risk Classification System. JACC Cardiovasc Imaging 2024; 17:62-75.

Abstract
BACKGROUND Carotid artery atherosclerosis is highly prevalent in the general population and is a well-established risk factor for acute ischemic stroke. Although the morphological characteristics of vulnerable plaques are well recognized, there is a lack of consensus in reporting and interpreting carotid plaque features. OBJECTIVES The aim of this paper is to establish a consistent and comprehensive approach for imaging and reporting carotid plaque by introducing the Plaque-RADS (Reporting and Data System) score. METHODS A panel of experts recognized the necessity to develop a classification system for carotid plaque and its defining characteristics. Using a multimodality analysis approach, the Plaque-RADS categories were established through consensus, drawing on existing published reports. RESULTS The authors present a universal classification that is applicable to both researchers and clinicians. The Plaque-RADS score offers a morphological assessment in addition to the prevailing quantitative parameter of "stenosis." The Plaque-RADS score spans from grade 1 (indicating complete absence of plaque) to grade 4 (representing complicated plaque). Accompanying visual examples are included to facilitate a clear understanding of the Plaque-RADS categories. CONCLUSIONS Plaque-RADS is a standardized and reliable system of reporting carotid plaque composition and morphology via different imaging modalities, such as ultrasound, computed tomography, and magnetic resonance imaging. This scoring system has the potential to help in the precise identification of patients who may benefit from exclusive medical intervention and those who require alternative treatments, thereby enhancing patient care. A standardized lexicon and structured reporting promise to enhance communication between radiologists, referring clinicians, and scientists.

Abstract
The GORE EXCLUDER Conformable abdominal aortic aneurysm (AAA) Endoprosthesis (CEXC), is currently the newest stent-graft system for treating patients with AAA. CEXC is approved for patients with proximal aortic neck angles ≤90° with a ≥15 mm aortic neck length or proximal aortic neck angles ≤60° with ≥10 mm aortic neck length. The present study describes a clinical series of 5 males with AAA, one of whom had a ruptured infrarenal AAA and a 90° proximal aortic neck angle. All patients were treated with 100% technical success using the CEXC device. Dosimetric data were recorded regarding the total kerma-area product and total fluoroscopy time. During the 30-day follow-up, no device migration or failure was detected, whereas type Ib and II endoleaks were observed in two patients. The type Ib endoleak required re-intervention with limb extension placement, and the type II endoleak was treated with lumbar artery embolization. This clinical series showed that CEXC has no technical defects or AAA-related mortality. We also reviewed the current knowledge on CEXC's clinical outcomes, showing promising technical and clinical results in some studies, even outside the instructions for use. CEXC expands the vascular surgeons' armamentarium against hostile neck anatomy, as it is the only repositionable endovascular aneurysm repair device available. Multicenter, long-term outcome studies should confirm the promising preliminary results of our case series and the literature review.

Abstract
BACKGROUND Arteriovenous grafts (AVGs) are used for patients deemed unsuitable for the creation of an autogenous arteriovenous fistula (AVF) or unable to await maturation of the AVF before starting hemodialysis. However, AVGs are prone to infection and thrombosis resulting in low long-term patency rates. The novel aXess Hemodialysis Graft consists of porous polymeric biomaterial allowing the infiltration by cells and the growth of neotissue, while the graft itself is gradually absorbed, ultimately resulting in a fully functional natural blood vessel. The Pivotal Study will examine the long-term effectiveness and safety of the aXess Hemodialysis Graft. METHODS The Pivotal Study is a prospective, single-arm, multicenter study that will be conducted in 110 subjects with end-stage renal disease who are not deemed suitable for the creation of an autogenous vascular access. The primary efficacy endpoint will be the primary patency rate at 6 months. The primary safety endpoint will be the freedom from device-related serious adverse events at 6 months. The secondary endpoints will include the procedural success rate, time to first cannulation, patency rates, the rate of access-related interventions to maintain patency, the freedom from device-related serious adverse events and the rate of access site infections. Patients will be followed for 60 months. An exploratory Health Economic and Outcomes Research sub-study will determine potential additional benefits of the aXess graft to patients, health care institutions, and reimbursement programs. DISCUSSION The Pivotal study will examine the long-term performance and safety of the aXess Hemodialysis Graft and compare the outcome measures with historical data obtained with other graft types and autogenous AVFs. Potential advantages may include superior long-term patency rates and lower infection rates versus currently available AVGs and a shorter time to first cannulation compared to an autologous AVF. As such, the aXess Hemodialysis Graft may fulfill an unmet clinical need in the field of hemodialysis access.

FACTORS INFLUENCING FLUOROSCOPY TIME IN ENDOVASCULAR TREATMENT OF ABDOMINAL ANEURYSMS: A RETROSPECTIVE STUDY. RADIATION PROTECTION DOSIMETRY 2023; 199:443-452.

Abstract
Patients who undergo endovascular aortic aneurysm repair (EVAR) may require prolonged radiation exposure affected by several factors. The objectives of this study were to document fluoroscopy time (FT) during EVAR and identify possible factors that influence it. A retrospective analysis of a 180 patients' database with abdominal infrarenal aortic aneurysms submitted to EVAR during a 7-y period was performed. The FT is evaluated regarding risk factors and comorbidities, graft type and patient-related, clinical and technical parameters. FT's median (interquartile range) was 1011 (698-1500) s. Excluder and C3 Excluder were associated with significantly lower FT values when compared with other grafts. Hypertension, dyslipidemia, age ≥ 70 y, maximum aneurysm diameter ≥ 6 cm and procedure duration ≥2 h resulted in higher FT values. A significantly lower FT was found for the operations performed in the 7th y of the study's period compared with the previous 6 y, mainly because of the use of Excluder or C3 Excluder grafts. However, these grafts did not show any significant difference in FT values during the 7 y. A significant correlation between FT with age and procedure duration was found. Nevertheless, procedure duration is a poor FT predictor in linear and logistic regressions, although is significantly correlated with FT. Dyslipidemia, procedure duration and graft type are independent predictors of FT larger than the median, whereas only the procedure duration is a predictor for FT larger than the 75th percentile value. The identified factors regarding radiation protection issues should be considered when contemplating abdominal aortic aneurysm repair, however, without compromising the procedure's efficacy. Further work is necessary to identify more potential anatomical, clinical and technical factors affecting procedures' complexity and FT and patient radiation dose during EVAR interventions.

Abstract
Vascular handlebar syndrome with blunt injury of the common femoral artery is a rare vascular trauma mechanism, with high possibility of being missed or delayed. We present two cases of vascular handlebar syndrome treated in our hospital and a systematic review of the literature using MEDLINE and SCOPUS databases. Literature review identified 20 similar cases. The median age of patients was 18 years, and in vast majority males in gender. In most cases, the common femoral artery injury was an intimal flap and lumen occlusion with intramural thrombosis followed by transection and intimal injury without occlusion or thrombosis. The median time between injury and diagnosis/treatment was half an hour. Clinical presentation ranged from asymptomatic to acute limb ischemia. The grade of acute ischemia was mostly Rutherford class I (n=14), while acute IIa (n=4), chronic ischemia (n=3), and no ischemia (n=1) were also noticed. The correct diagnosis was revealed by clinical examination only (n=1), or by the combination of clinical and imaging techniques including computed tomography angiography (n=7) and duplex ultrasonography (n=4) or both (n=10). Management of the handlebar trauma syndrome injuries was surgical in most cases. Outcome was favorable in all patients. Vascular handlebar syndrome is extremely rare and high suspicion is required for early diagnosis and definitive treatment, as the early management is effective and crucial for averting the devastating consequences. An individualized approach to the vascular trauma patient is to be applied with considerations taken to the age of the patient, the mechanism of the injury, the anatomy of the lesion, and symptomatology of the case.

Why do guidelines recommend screening for abdominal aortic aneurysms, but not for asymptomatic carotid stenosis? A plea for a randomized controlled trial. Int J Cardiol 2023; 371:406-412.

Abstract
BACKGROUND Current guidelines do not recommend screening for asymptomatic carotid artery stenosis (AsxCS). The rationale behind this recommendation is that detection of AsxCS may lead to an unnecessary carotid intervention. In contrast, screening for abdominal aortic aneurysms is strongly recommended. METHODS A critical analysis of the literature was performed to evaluate the implications of detecting AsxCS. RESULTS Patients with AsxCS are at high risk for future stroke, myocardial infarction and vascular death. Population-wide screening for AsxCS should not be recommended. Additionally, screening of high-risk individuals for AsxCS with the purpose of identifying candidates for a carotid intervention is inappropriate. Instead, selective screening for AsxCS should be considered and should be viewed as an opportunity to identify individuals at high risk for atherosclerotic cardiovascular disease and future cardiovascular events for the timely initiation of intensive medical therapy and risk factor modification. CONCLUSIONS Although mass screening should not be recommended, there are several arguments suggesting that selective screening for AsxCS should be considered. The rationale supporting such selective screening is to optimize risk factor control and to initiate intensive medical therapy for prevention of future cardiovascular events, rather than to identify candidates for an intervention.

Abstract
OBJECTIVES To evaluate the risk of symptomatic venous thromboembolism (VTE) recurrence at 3 months in relation to treatment duration, according to baseline risk factor profiles, in patients with superficial vein thrombosis (SVT) treated with intermediate dose of tinzaparin. METHODS We performed a pooled analysis on individual data from two prospective studies designed to assess the efficacy and safety of tinzaparin in intermediate dose (131 IU/kg) in patients with SVT. Treatment duration was at the treating physician's discretion. All patients were followed up for at least 3 months. RESULTS A total of 956 patients (65% female, mean age 58.7 ± 13.7 years) were included. The median treatment duration was 30 days (range, 3-200 days). History of deep vein thrombosis (DVT), location of SVT above the knee, and palpable induration were the only independent factors associated with prolonged treatment duration. During follow-up, 95.9% of patients were event free. Outcomes-related adverse events occurred in 39 (4.1%) patients and their median duration of treatment was 33 days (range, 7-200 days). Recurrent VTE events occurred in 33 patients, including 22 cases of SVT recurrence, 8 cases of DVT, and 1 case of pulmonary embolism. The median time to the event was 29 (6-113) days. Recurrent thromboembolic events were not related to treatment duration as occurred in 17 patients (51.5%) treated up to 30 days and in 16 patients (48.8%) received prolong treatment (p = .46). Length of thrombus at the index event was significantly associated with higher risk for VTE recurrence. CONCLUSIONS Intermediate dose of tinzaparin for 30 days is an effective and safe treatment for SVT. The risk of recurrent VTE events may be higher in patients with greater amount of thrombus at index event.

Abstract
OBJECTIVES The role of antithrombotic therapy in the management of aortic and peripheral aneurysms is unclear. This systematic review and meta-analysis aimed to assess the impact of antithrombotics on clinical outcomes for aortic and peripheral aneurysms. METHODS Medline, Embase, and CENTRAL databases were searched. Randomised controlled trials and observational studies investigating the effect of antithrombotic therapy on clinical outcomes for patients with any aortic or peripheral artery aneurysm were included. RESULTS Fifty-nine studies (28 with antiplatelet agents, 12 anticoagulants, two intra-operative heparin, and 16 any antithrombotic agent) involving 122 102 patients were included. Abdominal aortic aneurysm (AAA) growth rate was not significantly associated with the use of antiplatelet therapy (SMD -0.36 mm/year; 95% CI -0.75 - 0.02; p = .060; GRADE certainty: very low). Antithrombotics were associated with increased 30 day mortality for patients with AAAs undergoing intervention (OR 2.30; 95% CI 1.51 - 3.51; p < .001; GRADE certainty: low). Following intervention, antiplatelet therapy was associated with reduced long term all cause mortality (HR 0.84; 95% CI 0.76 - 0.92; p < .001; GRADE certainty: moderate), whilst anticoagulants were associated with increased all cause mortality (HR 1.64; 95% CI 1.14 - 2.37; p = .008; GRADE certainty: very low), endoleak within three years (OR 1.99; 95% CI 1.10 - 3.60; p = .020; I2 = 60%; GRADE certainty: very low), and an increased re-intervention rate at one year (OR 3.25; 95% CI 1.82 - 5.82; p < .001; I2 = 35%; GRADE certainty: moderate). Five studies examined antithrombotic therapy for popliteal aneurysms. Meta-analysis was not possible due to heterogeneity. CONCLUSIONS There was a lack of high quality data examining antithrombotic therapy for patients with aneurysms. Antiplatelet therapy was associated with a reduction in post-intervention all cause mortality for AAA, whilst anticoagulants were associated with an increased risk of all cause mortality, endoleak, and re-intervention. Large, well designed trials are still required to determine the therapeutic benefits of antithrombotic agents in this setting.

Abstract
Abstract
Introduction
The role of antithrombotic agents in aneurysm progression and outcomes following surgical or endovascular intervention is unclear.
Methods
A systematic review and meta-analysis was performed. Medline, Embase, and CENTRAL databases were searched. Randomised-controlled trials and observational studies investigating the effect of antithrombotic therapy on clinical outcomes for patients with aortic or extracranial peripheral arterial aneurysms were included. Aneurysm growth rate, major adverse cardiovascular or limb events, mortality, endoleaks, re-intervention rates, and other outcomes were captured.
Results
Fifty-seven studies involving 121,451 patients were included (26 antiplatelets, 12 anticoagulants, 16 any antithrombotic agent(s), 2 intra-operative heparin). Aspirin reduced growth rates of aortic aneurysms under surveillance (mean difference -0.9mm/y, 95%CI -1.74 to -0.07, p=0.03; GRADE certainty: moderate). For aortic aneurysms undergoing intervention, anti-thrombotics increased 30-day mortality (odds ratio [OR] 2.30, 95%CI 1.51 to 3.51, p<0.001; GRADE certainty: moderate). Antiplatelets reduced long-term all-cause mortality (hazard ratio [HR] 0.84, 95%CI 0.76 to 0.92, p<0.001; GRADE certainty: moderate), whilst anticoagulants increased this risk (HR 1.64, 95%CI 1.14 to 2.37, p=0.008; GRADE certainty: very low). Anticoagulants increased incidence of endoleaks under 3 years, and re-intervention rates (p<0.05 for all). Antithrombotic agents did not significantly affect rupture rates in aortic aneurysms. Meta-analysis was not possible for ruptured aneurysms and popliteal aneurysms.
Conclusion
There is moderate quality evidence that aspirin reduces aneurysm growth rates. Antiplatelet agents reduced all-cause mortality in aneurysms after intervention; whilst anticoagulants increased this risk, along with endoleaks and re-interventions. Well-designed trials are required to determine therapeutic benefits of antithrombotic agents for patients with aneurysms.
Take-home message
Antiplatelets may have a role in reducing aneurysm growth rates and all-cause mortality; whilst anticoagulants are associated with increased mortality, endoleaks, and re-interventions. Well-designed trials are required to determine therapeutic benefits of antithrombotic agents for patients with aneurysms.

Abstract
The ALTO abdominal stent graft system (Endologix Inc., Irvine, CA, USA) is a latest-generation polymer-based device used to treat patients with abdominal aortic aneurysms. The present study describes the first case series of patients with abdominal aortic aneurysms, including two patients with juxtarenal aneurysms, treated using the ALTO stent graft system. Six males were treated using the ALTO device at a single public center. All procedures were uneventful, and the dosimetric results recorded in terms of kerma-area product and fluoroscopy time were similar to those reported in previous studies. At the 1-month follow-up, computed tomography angiography showed no evidence of endoleak, device migration, thrombosis, or structural graft failure. This clinical series demonstrates that the use of the ALTO stent graft system is associated with promising patient outcomes. Lifelong postoperative imaging surveillance may highlight possible late failures and suggest potential graft improvements.

Abstract
BACKGROUND IL-6 (interleukin-6) has important roles in atherosclerosis pathophysiology. To determine if anti-IL-6 therapy warrants evaluation as an adjuvant stroke prevention strategy in patients with carotid atherosclerosis, we tested whether circulating IL-6 levels predict carotid plaque severity, vulnerability, and progression in the prospective population-based CHS (Cardiovascular Health Study). METHODS Duplex carotid ultrasound was performed at baseline and 5 years. Baseline plaque severity was scored 0 to 5 based on North American Symptomatic Carotid Endarterectomy Trial grade of stenosis. Plaque vulnerability at baseline was the presence of markedly irregular, ulcerated, or echolucent plaques. Plaque progression at 5 years was a ≥1 point increase in stenosis severity. The relationship of baseline plasma IL-6 levels with plaque characteristics was modeled using multivariable linear (severity) or logistic (vulnerability and progression) regression. Risk factors of atherosclerosis were included as independent variables. Stepwise backward elimination was used with P>0.05 for variable removal. To assess model stability, we computed the E-value or minimum strength of association (odds ratio scale) that unmeasured confounders must have with log IL-6 and the outcome to suppress the association. We performed internal validation with 100 bootstrap samples. RESULTS There were 4334 participants with complete data (58.9% women, mean age: 72.7±5.1 years), including 1267 (29.2%) with vulnerable plaque and 1474 (34.0%) with plaque progression. Log IL-6 predicted plaque severity (β=0.09, P=1.3×10-3), vulnerability (OR, 1.21 [95% CI, 1.05-1.40]; P=7.4×10-3, E-value=1.71), and progression (OR, 1.44 [95% CI, 1.23-1.69], P=9.1×10-6, E-value 2.24). In participants with >50% predicted probability of progression, mean log IL-6 was 0.54 corresponding to 2.0 pg/mL. Dichotomizing IL-6 levels did not affect the performance of prediction models. CONCLUSIONS Circulating IL-6 predicts carotid plaque severity, vulnerability, and progression. The 2.0 pg/mL cutoff could facilitate the selection of individuals that would benefit from anti-IL-6 drugs for stroke prevention.

Extended Anticoagulation for Venous Thromboembolism: A Survey of the American Venous Forum and the European Venous Forum. J Vasc Surg Venous Lymphat Disord 2022; 10:1012-1020.e3.

Abstract
OBJECTIVE Extended anticoagulation should always be considered after standard treatment for an unprovoked episode of venous thromboembolism (VTE). It may also be considered in selected patients with provoked VTE. However, evidence-based protocols suggested by some clinical guidelines and risk assessment tools to guide this practice are limited and ambiguous. The goal of this survey research was to analyze current practices in applying extended anticoagulation therapy in patients with VTE among members of the American Venous Forum (AVF) and the European Venous Forum (EVF). METHODS An online survey was created by the AVF Research Committee. The survey consisted of sixteen questions to identify the country of practice, specialty, experience of participating physicians, and their clinical practice patterns in applying extended anticoagulation in VTE patients. The survey was distributed over email to the members of the AVF and EVF. RESULTS A total of 144 practitioners, 48 (33%) AVF members and 96 (66%) EVF members, participated in the survey. The majority of respondents identified themselves as vascular specialists with primary certification in vascular surgery (70%), vascular medicine/angiology (9%), and venous disease/phlebology (3%). Seventy-two percent of participants believe that the risk of VTE recurrence generally overweighs the risk of bleeding in patients with unprovoked VTE. Extended anticoagulation may be utilized by 97% of providers. Different patterns in real world clinical practice were identified. More than half of practitioners estimated VTE recurrence and bleeding risk subjectively. The antithrombotic drugs most commonly used for secondary prophylaxis were rivaroxaban, apixaban, warfarin, dabigatran, and aspirin, in decreasing order of frequency. Among the reasons selected for not considering extended anticoagulation on a regular basis were the lack of specific clinical practice guidelines (24%), the lack of published evidence (9%), and the absence of valid VTE/bleeding risk prediction calculators (8%). Twelve participants (8%) stated that extended anticoagulation was not beneficial for the majority of patients with VTE. Ten participants (7%) indicated that prescribing extended anticoagulation was outside the scope of their specialty. CONCLUSIONS There are different practice patterns in extending anticoagulation beyond the standard treatment in patients with VTE. Major gaps in knowledge remain a serious challenge at least partially explaining inaccuracy and inconsistency in long-term VTE management. Appropriately designed studies are needed to evaluate risk stratification tools when contemporary best medical therapy is used, accurately predict VTE recurrence and its long-term outcomes, and to tailor safe and effective secondary prophylaxis.

Abstract
Despite the publication of several national/international guidelines, the optimal management of patients with asymptomatic carotid stenosis (AsxCS) remains controversial. This article compares 3 recently released guidelines (the 2020 German-Austrian, the 2021 European Stroke Organization [ESO], and the 2021 Society for Vascular Surgery [SVS] guidelines) vs the 2017 European Society for Vascular Surgery (ESVS) guidelines regarding the optimal management of AsxCS patients.The 2017 ESVS guidelines defined specific imaging/clinical parameters that may identify patient subgroups at high future stroke risk and recommended that carotid endarterectomy (CEA) should or carotid artery stenting (CAS) may be considered for these individuals. The 2020 German-Austrian guidelines provided similar recommendations with the 2017 ESVS Guidelines. The 2021 ESO Guidelines also recommended CEA for AsxCS patients at high risk for stroke on best medical treatment (BMT), but recommended against routine use of CAS in these patients. Finally, the SVS guidelines provided a strong recommendation for CEA+BMT vs BMT alone for low-surgical risk patients with >70% AsxCS. Thus, the ESVS, German-Austrian, and ESO guidelines concurred that all AsxCS patients should receive risk factor modification and BMT, but CEA should or CAS may also be considered for certain AsxCS patient subgroups at high risk for future ipsilateral ischemic stroke.

Abstract
Limb ischemia is a known complication of vascular access that may appear early postoperatively or after years. Over the last few decades, various techniques based on different physiological mechanisms have been used for treatment. A standardized treatment does not exist, and must be individualized based on the flow volume, and the type and location of the access. True and false vascular access aneurysms are another common complication of arteriovenous fistulas, which develop because of venous hypertension or repeated needling. Evidence in the literature regarding treatment of patients with steal syndrome and concomitant true arteriovenous aneurysms is scarce. A female with a brachiocephalic fistula complicated by steal syndrome and vascular access aneurysms was treated successfully with tapered graft placement and aneurysm exclusion.

Abstract
OBJECTIVES The recommendations of international guidelines for the management of asymptomatic carotid stenosis (ACS) often vary considerably and extend from a conservative approach with risk factor modification and best medical treatment (BMT) alone, to a more aggressive approach with a carotid intervention plus BMT. The aim of the current multispecialty position statement is to reconcile the conflicting views on the topic. MATERIALS AND METHODS A literature review was performed with a focus on data from recent studies. RESULTS Several clinical and imaging high-risk features have been identified that are associated with an increased long-term ipsilateral ischemic stroke risk in patients with ACS. Such high-risk clinical/imaging features include intraplaque hemorrhage, impaired cerebrovascular reserve, carotid plaque echolucency/ulceration/ neovascularization, a lipid-rich necrotic core, a thin or ruptured fibrous cap, silent brain infarction, a contralateral transient ischemic attack/stroke episode, male patients <75 years and microembolic signals on transcranial Doppler. There is growing evidence that 80-99% ACS indicate a higher stroke risk than 50-79% stenoses. CONCLUSIONS Although aggressive risk factor control and BMT should be implemented in all ACS patients, several high-risk features that may increase the risk of a future cerebrovascular event are now documented. Consequently, some guidelines recommend a prophylactic carotid intervention in high-risk patients to prevent future cerebrovascular events. Until the results of the much-anticipated randomized controlled trials emerge, the jury is still out regarding the optimal management of ACS patients.

Abstract
OBJECTIVE Adenosine diphosphate (ADP) receptor inhibitors such as clopidogrel are known to be less effective at reducing platelet function for some patients because of a phenomenon called high on-treatment platelet reactivity (HTPR). However, the clinical effect of this for patients undergoing endovascular intervention for peripheral arterial disease is unclear. The aim of this study was to assess the impact of ADP receptor inhibitor HTPR on clinical outcomes following lower limb arterial endovascular intervention for peripheral arterial disease. METHODS A systematic review and meta-analysis was performed. Primary outcomes included all cause mortality and major bleeding. Secondary outcomes were major adverse cardiovascular events, major adverse limb events, restenosis, and target lesion revascularisation. Outcome quality was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. RESULTS There were 10 eligible studies including 1 444 patients included in the meta-analysis. The most commonly tested ADP receptor inhibitor was clopidogrel (seven studies). The pooled rate of ADP receptor inhibitor HTPR was 29% (95% CI 27 - 32). The meta-analysis showed that ADP receptor inhibitor HTPR was associated with a greater risk of major adverse limb events (OR 6.25, 95% CI 2.09 - 18.68, p = .001) and a trend towards a higher all cause mortality (OR 1.71, 95% CI 0.99 - 2.94, p = .050) and more major adverse cardiovascular events (OR 4.23, 95% CI 0.46 - 38.92, p = .20) after endovascular intervention. Overall strength of evidence was very low for all outcomes. CONCLUSION ADP receptor inhibitor HTPR was associated with worse clinical outcomes after lower limb endovascular intervention for peripheral arterial disease. Prospective studies are required to determine the impact of modifying the antithrombotic regimen on clinical outcomes.

Abstract
Revascularization of the internal iliac artery during open repair of aortoiliac aneurysms can be challenging, especially if there is a significant distance between the orifices of the internal and external iliac arteries owing to common iliac aneurysmal dilatation. We describe a technique involving insertion of an 18-mm tube graft between the proximal aortic neck and aneurysmal common iliac artery bifurcation. Revascularization of the contralateral external iliac artery is accomplished through an 8-mm side arm graft.

Abstract
The optimal management of patients with asymptomatic carotid stenosis (ACS) is the subject of extensive debate. According to the 2017 European Society for Vascular Surgery guidelines, carotid endarterectomy should (Class IIa; Level of Evidence: B) or carotid artery stenting may be considered (Class IIb; Level of Evidence: B) in the presence of one or more clinical/imaging characteristics that may be associated with an increased risk of late ipsilateral stroke (e.g. silent embolic infarcts on brain computed tomography/magnetic resonance imaging, progression in the severity of ACS, a history of contralateral transient ischemic attack/stroke, microemboli detection on transcranial Doppler, etc.), provided documented perioperative stroke/death rates are <3% and the patient's life expectancy is >5 years. Besides these clinical/imaging characteristics, there are additional individual, ethnic/racial or social factors that should probably be evaluated in the decision process regarding the optimal management of these patients, such as individual patient needs/patient choice, patient compliance with best medical treatment, patient sex, culture, race/ethnicity, age and comorbidities, as well as improvements in imaging/operative techniques/outcomes. The present multispecialty position paper will present the rationale why the management of patients with ACS may need to be individualized.

KERMA-AREA PRODUCT, ENTRANCE SURFACE DOSE AND EFFECTIVE DOSE IN ABDOMINAL ENDOVASCULAR ANEURYSM REPAIR. RADIATION PROTECTION DOSIMETRY 2021; 194:121-134. [PMID: 34227656 DOI: 10.1093/rpd/ncab082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2021] [Revised: 04/15/2021] [Accepted: 05/09/2021] [Indexed: 06/13/2023]
Abstract
This study aims to evaluate patient radiation dose during fluoroscopically guided endovascular aneurysm repair (EVAR) procedures. Fluoroscopy time (FT) and kerma-area product (KAP) were recorded from 87 patients that underwent EVAR procedures with a mobile C-arm fluoroscopy system. Effective dose (ED) and organs' doses were calculated utilising appropriate conversion coefficients based on the recorded KAP values. Entrance surface dose (ESD) was calculated based on KAP values and technical parameters. The mean FT was 22.7 min (range 6.4-76.8 min), resulting in a mean KAP of 36.6 Gy cm2 (range 2.0-167.8 Gy cm2), a mean ED of 6.2 mSv (range 0.3-28.5 mSv) and a mean ESD of 458 mGy (range 26-2098 mGy). The corresponding median values were 17.4 min, 25.6 Gy cm2, 4.4 mSv and 320 mGy. The threshold of 2 Gy for skin erythema was exceeded in two procedures for a focus-to-skin distance (FSD) of 40 cm and six procedures when an FSD of 30 cm was considered. The highest doses absorbed by the adrenals, kidneys, spleen and pancreas and ranged between 3.7 and 313.3 mGy (average 66.8 mGy), 3.3 and 285.1 mGy (average 60.8 mGy), 1.3 and 111.1 mGy (average 23.7 mGy), 1.1 and 92.1 mGy (average 19.6 mGy), respectively. A wide range of patient doses was reported in the literature. The radiation dose received by the patients was comparative or lower than most of the previously reported values. However, higher doses can be revealed due to the X-ray system's non-optimum use and extended FTs, mainly affected by complex clinical conditions, patients' body habitus and vascular surgeon experience. The large variation of patient doses highlights the potential to optimise the EVAR procedure by considering the balance between the radiation dose and the required image quality. Additional studies need to be conducted in increasing the vascular surgeons' awareness regarding patient dose and radiation protection issues during EVAR procedures.

A Systematic Review and Meta-analysis of Peri-Procedural Outcomes in Patients Undergoing Carotid Interventions Following Thrombolysis. Eur J Vasc Endovasc Surg 2021; 62:340-349. [PMID: 34266765 DOI: 10.1016/j.ejvs.2021.06.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 06/01/2021] [Accepted: 06/03/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To evaluate the safety of carotid artery stenting (CAS) and carotid endarterectomy (CEA) after thrombolytic therapy (TT). DATA SOURCES Medline, Scopus, and Cochrane databases. REVIEW METHODS Systematic review and meta-analysis of studies involving patients who underwent CEA/CAS after TT. RESULTS In 25 studies (n = 147 810 patients), 2 557 underwent CEA (n = 2 076) or CAS (n = 481) following TT. After CEA, the pooled peri-procedural stroke/death rate was 5.2% (95% confidence interval [CI] 3.3 - 7.5) and intracranial haemorrhage (ICH) was 3.4% (95% CI 1.7 - 5.6). After CAS, the pooled peri-procedural stroke/death rate was 14.9% (95% CI 11.9 - 18.2) and ICH was 5.5% (95% CI 3.7 - 7.7). In case control studies comparing CEA outcomes in patients receiving TT vs. no TT, peri-procedural death/stroke was non-significantly higher after TT (4.3% vs. 1.5%; odds ratio [OR] 2.34, 95% CI 0.74 - 7.47), but ICH was significantly higher after TT (2.2% vs. 0.12%; OR 7.82, 95% CI 4.07 - 15.02), as was local haematoma formation (3.6% vs. 2.26%; OR 1.17, 95% CI 1.17 - 2.33). In case control studies comparing CAS outcomes in patients receiving TT vs. no TT, peri-procedural stroke/death was significantly higher after TT (5.2% vs. 1.5%; OR 8.49, 95% CI 2.12 - 33.95) as was ICH (5.4% vs. 0.7%; OR 7.48, 95% CI 4.69 - 11.92). Meta-regression analysis demonstrated an inverse association between the time interval from intravenous (IV) TT to undergoing CEA and the risk of peri-procedural stroke/death (p = .032). Peri-operative stroke/death was 13.0% when CEA was performed three days after TT and 10.6% when performed four days after TT, with the risk reducing to within the currently accepted 6% threshold after six-seven days had elapsed. CONCLUSION Peri-procedural ICH and local haematoma were significantly more frequent in patients undergoing CEA after TT (vs. no TT), although there were no randomised comparisons. Peri-procedural hazards were also significantly higher for CAS after TT. The inverse relationship between timing to CEA and peri-procedural stroke/death mandates careful patient selection and suggests that it may be safer to defer CEA for six-seven days after TT.

Abstract
The optimal management of patients with asymptomatic carotid stenosis (ACS) is the subject of extensive debate. According to the 2017 European Society for Vascular Surgery guidelines, carotid endarterectomy should (Class IIa; Level of Evidence: B) or carotid artery stenting may be considered (Class IIb; Level of Evidence: B) in the presence of one or more clinical/imaging characteristics that may be associated with an increased risk of late ipsilateral stroke (e.g., silent embolic infarcts on brain computed tomography/magnetic resonance imaging, progression in the severity of ACS, a history of contralateral transient ischemic attack/stroke, microemboli detection on transcranial Doppler, etc.), provided documented perioperative stroke/death rates are <3% and the patient’s life expectancy is >5 years. Besides these clinical/imaging characteristics, there are additional individual, ethnic/racial or social factors that should probably be evaluated in the decision process regarding the optimal management of these patients, such as individual patient needs/patient choice, patient compliance with best medical treatment, patient sex, culture, race/ethnicity, age and comorbidities, as well as improvements in imaging/operative techniques/outcomes. The present multispecialty position paper will present the rationale why the management of patients with ACS may need to be individualized.

Abstract
OBJECTIVE To assess the clinical efficacy of sulodexide, including a comparison with venoactive drugs (VAD) (micronized purified flavonoid fraction, MPFF; hydroxy-ethyl-rutosides, HR; calcium dobesilate;Ruscus extract combined with hesperidin methyl chalcone and vitamin C, Ruscus+HMC+VitC; horse chestnut seed extract, HCSE) and pentoxifylline in patients with chronic venous disease. METHODS We performed a literature search in MEDLINE, Embase, and Cochrane Library for randomized controlled trials (RCTs) and observational studies. Proportion of patients with complete venous ulcer healing was the primary outcome and lower leg volume, foot volume, ankle circumference and symptoms were the secondary outcomes. Bayesian network meta-analysis (NMA) was perfomed with random effects models using only RCTs. A meta-analysis of observational studies was performed for sulodexide because no RCT could be included in NMA for symptoms or signs. RESULTS Forty-five RCTs and eighteen observational studies were identified. Sulodexide was included only in a single NMA for the proportion of patients with complete ulcer healing and it showed to have the highest probability of being the best treatment (48%) compared with pentoxifylline (37%) and MPFF (16%). MPFF was the most effective treatment in reducing lower leg volume, CIVIQ-20 score and pain VAS scale while calcium dobesilate and Ruscus+HMC+VitC were the most effective in reducing foot volume and ankle circumference respectively.Meta-analyses of observational studies for sulodexide showed that it improves significantly the scoring of pain, feeling of swelling, heaviness and parasthesiae measured by Likert scales. CONCLUSIONS Sulodexide is at least as effective as pentoxifylline and more effective than MPFF in improving the rate of ulcer healing in patients with CVD. VADs are effective in improving venous symptoms and signs, as was also shown by sulodexide in the meta-analysis of observational studies. The relative effectiveness of sulodexide and VADs needs to be evaluated by an RCT in order to better inform clinical practice.

Abstract
We report a case of successful open repair of a 7.5-cm juxtarenal abdominal aortic aneurysm (AAA) in the presence of a left-sided inferior vena cava (LS-IVC) crossing the aorta at the level of the renal arteries in a 72-year-old man. The orifice of the right renal artery was slightly caudal to that of the left renal artery and concomitant occlusive diseases of both iliac arteries were present. Based on the imaging and intraoperative findings, repair of the juxtarenal AAA was performed with mobilization of the LS-IVC, which was encircled twice with soft silicone rubber vessel loops on both sides of operating field and the blood content of the LS-IVC was temporarily evacuated. This procedure allowed proximal control with inter-renal clamping of the aorta and placement of an aortobifemoral polytetrafluoroethylene graft.

Abstract
OBJECTIVES To describe the frequency, factors associated with, and significance of surgical dissection maneuvers of the distal internal carotid artery (ICA) during carotid endarterectomy (CEA). METHODS In this retrospective analysis of prospectively collected information in patients undergoing CEA, we recorded information on demographics, risk factors and comorbidities, dissection maneuvers of the distal ICA, other operative variables and neurological outcome measures. RESULTS During the period July 2008 and February 2020 inclusive, 218 consecutive patients (180 males, median age 69.5 years) underwent 240 CEAs. In 117 (48.8%) of them, CEA was performed for a symptomatic stenosis. Dissection maneuvers of the distal ICA were required in 77 cases (32.1%), including division and ligation of the sternocleidomastoid vessels in 66 cases (27.5%), mobilization of the XII cranial nerve in 69 cases (28.7%, with concomitant transection of the superior root of the ansa cervicalis in 11 cases, 4.6%) and division of the posterior belly of the digastric muscle in 8 cases (3.3%). Styloid osteotomy was not required in any case. Smoking was the single predictive factor associated with the use of an adjunctive dissection maneuver (odds ratio 2.23, p = 0.009). The use of a patch was more common in smokers (16% vs 7.1% in non-smokers, odds ratio 2.48, p = 0.05). Perioperative stroke and/or death rate was 0%, not allowing testing for associations with maneuver performance. Two patients (0.8%) developed a transient ischemic attack and 4 patients (1.7%) a cranial nerve injury (CNI), including 2 patients with recurrent laryngeal nerve palsy, diagnosed on routine laryngoscopy during planning of a contralateral CEA. There was no association between CNI and dissection of the distal ICA using an operative adjunct (p = 0.60). CONCLUSIONS Several surgical maneuvers are often required to accomplish dissection of the distal ICA beyond the point of atherosclerotic disease. When dictated by operative findings, such maneuvers are deemed safe.
