Abstract
Heart failure has a poor prognosis and no curative treatment exists. Clinical trials are investigating gene- and cell-based therapies to improve cardiac function. The safe and efficient delivery of these therapies to solid organs is challenging. Herein, we demonstrate the feasibility of using an endovascular intramyocardial delivery approach to safely administer mRNA drug products and perform cell transplantation procedures in swine. Using a trans-vessel wall (TW) device, we delivered chemically modified mRNAs (modRNA) and mRNA-enhanced mesenchymal stromal cells expressing vascular endothelial growth factor A (VEGF-A) directly to the heart. We monitored and mapped the cellular distribution, protein expression, and safety tolerability of such an approach. The delivery of modRNA-enhanced cells via the TW device with different flow rates and cell concentrations marginally affect cell viability and protein expression in situ. Implanted cells were found within the myocardium for at least 3 days following administration, without the use of immunomodulation and minimal impact on tissue integrity. Finally, we could increase the protein expression of VEGF-A over 500-fold in the heart using a cell-mediated modRNA delivery system compared with modRNA delivered in saline solution. Ultimately, this method paves the way for future research to pioneer new treatments for cardiac disease.

Abstract
OBJECTIVE Most surgeons employ an endovascular first approach to the treatment of peripheral arterial disease (PAD), but controversy remains regarding the ideal interventions for the management of isolated popliteal artery disease (IPAD). Indeed, there are a paucity of data that compare outcomes of popliteal stents versus other peripheral vascular interventions (PVI). The goal of this study was to evaluate outcomes of PVI in IPAD. METHODS The Vascular Study Group of New England database was queried for all IPAD PVI performed for atherosclerotic occlusive disease from 2010-2021. Those with at least one year of follow-up data available were included for analysis. The primary endpoint was one-year freedom from a composite target lesion (TL) treatment failure that included re-stenosis >50% on duplex, re-intervention, or ipsilateral major amputation. RESULTS We included 689 procedures performed on 634 patients. 250 (36.3%) were treated with plain balloons (POBA), 215 (31.2%) had stents, 170 (24.7%) had special balloons (drug-coated, cutting, or lithotripsy), and 54 (7.8%) atherectomies were performed. Stent placement was associated with lower freedom from TL treatment failure (72.6%) than special balloon (81.2%, p=0.048) and atherectomy (88.9%, p=0.012), but not POBA (76.8%, p=0.293). On multivariable logistic regression, stents (OR 0.637, p=0.021) and pre-operative P2Y12 inhibitor therapy (OR 0.683, p=0.048) were both associated with lower freedom from intervention failure. CONCLUSION Popliteal stent placement is associated with a higher rate of TL treatment failure at 1 year when compared with other PVI including special balloon angioplasty and atherectomy, but not POBA, and should therefore be avoided in favor of special balloons or atherectomy whenever feasible.

Abstract
Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this guideline the IWGDF, the European Society for Vascular Surgery and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development, and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

Abstract
Recurrence of a lung tumor invading the subclavian artery, causing stenosis and leading to finger ulcers as the initial symptom, is rare. We employed endovascular techniques, inserting a Viabahn® VBX covered stent (W. L. Gore & Associates, Flagstaff, Arizona) to aid in ulcer healing and improve the patient's quality of life. The patient, a 73-year-old male, had a history of lung adenocarcinoma resection two years prior but had not undergone follow-up examinations or cancer-specific treatments. Clinical examination revealed an invasion of the right subclavian artery by the recurrent tumor, resulting in severe stenosis and ischemic symptoms in the right upper limb. Given the patient's advanced cancer stage and the decline of further tumor-specific treatments, an endovascular intervention using a Viabahn VBX covered stent was performed to improve blood flow and promote ulcer healing. The stent demonstrated exceptional stability and patency during the six-month follow-up, greatly improving the patient's quality of life. This case highlights the importance of recognizing atypical symptoms as potential indicators of tumor recurrence or progression and demonstrates the promising role of covered stents in managing vascular complications in selected patients with advanced-stage malignancies.

Abstract
BACKGROUND Endovascular therapy offers an alternative for treating femoropopliteal (FP) and infrapopliteal (IP) lesions related to occlusive lower extremity artery disease. Despite numerous trials, the effectiveness of restenosis prevention using local drug delivery devices remains a topic of debate. OBJECTIVES An updated systematic review and network meta-analysis was conducted. Our overall aim was to summarize the most recent clinical evidence regarding endovascular approaches for FP and IP atherosclerotic lesions. METHODS We conducted a search for randomized trials in the MEDLINE database, and extracted data related to clinical endpoints. Our primary focus was on the rate of major adverse events (MAEs), including mortality, amputation, and target lesion revascularization (TLR). A multiple treatment network meta-analysis supplemented with component network analyses was performed to examine the impact of combined treatment. RESULTS Our search yielded 33 randomized controlled trials encompassing 5766 patients. This included 19 studies focused on femoropopliteal and 14 on IP lesions, accounting for 3565 and 2201 patients, respectively. Drug-coated balloons (DCBs) and drug-eluting stents (DESs) displayed a reduced MAE risk in comparison to plain old balloon angioplasty (POBA)-RR for DCB: 0.64 (95% CI: 0.52-0.77) and for DES: 0.71 (95% CI: 0.51-0.99). The bare-metal stent (BMS) group manifested the most substantial MAE risk, being 59% higher relative to the DCB cohort (BMS vs. DCB RR: 1.59; 95% CI: 1.03-2.47). For FP lesions, DES was the standout performer, curtailing MAE risk by 55% relative to POBA. Within IP lesions, DES mitigated the MAE risk by 25% versus POBA. DCB did not exhibit any notable MAE reduction when pitted against POBA. CONCLUSION In FP arteries, both DESs and DCBs yielded significantly diminished MAEs, thus outpacing other techniques. Regarding IP arteries, only DESs resulted in significantly fewer MAEs. In alignment with contemporary research, our findings revealed no signs of elevated mortality in patients undergoing treatment with drug-eluting apparatuses.

Abstract
This case report details the management of a 66-year-old male with hemophilia A (HA) who presented with recurrent hematuria, and was found to have renal artery aneurysms and was subsequently diagnosed with a renal arteriovenous (AV) shunt. While the primary focus centers on the successful endovascular coil embolization of renal artery aneurysms, the concomitant presence of the AV shunt accentuates the significance of this case. Imaging techniques were crucial in the discovery of renal aneurysms and the diagnosis of the AV shunt malformation of the renal artery. This included an ultrasound, CT-angiography and digital subtraction angiography. The treatment approach employed prioritized endovascular coil embolization for its efficacy and reduced morbidity. Following the initial successful embolization, the identification of the AV shunt during subsequent embolization led to its targeted treatment. The case was also complicated by acute prostatitis that was treated medically. The patient's HA required careful administration of coagulation factor replacement therapy to control bleeding throughout the process. This case highlights the importance of reporting on the management of rare and complex pathologies to better understand and guide future treatments, especially involving this rare combination of renal AV shunts and hemophilia A.

Abstract
INTRODUCTION In the last 2 decades, several studies in the literature evaluated the possible role of covered stents in the treatment of TransAtlantic Inter-Society Consensus (TASC) C and D femoropopliteal lesions but, despite the encouraging results, the employment of these devices was never included in clinical guidelines. The aim of this study is to evaluate the role of the technical aspects in patients with TASC C or D lesions that were treated with the GORE VIABAHN endoprosthesis and to elaborate a computerized method to objectively estimate the post-stent run-off and predict stent-graft failure. MATERIALS AND METHODS In this monocentric retrospective study, we collected the patients who were treated in our department from December 2014 to May 2021. Inclusion criteria comprised: (1) patients who underwent endovascular treatment of a TASC C or D femoropopliteal lesions using one or more heparin-bonded covered stent(s) and (2) clinical follow-up >2 years. Exclusion criteria were clinical follow-up <2 years or missing. An in-house computerized analysis to estimate the post-stent run-off, CEVERO (Computerized Estimation of VEssel Run-Off), was elaborated. RESULTS Sixty-six patients were enrolled in the study. Eleven patients had a TASC type C lesion, and 55 patients presented a type D lesion. The median follow-up time was 2.6 years. Twenty-nine patients (43.9%) experienced a major adverse limb event. Primary patency after 6, 12 and 24 months was 74.2%, 60.6%, and 57.6%; primary-assisted patency was 78.8%, 65.2%, and 59.1%. The presence of <2 run-off vessels (p<0.001) was correlated with stent-graft failure. The CEVERO analysis demonstrated an accuracy of 90.0% in predicting stent-graft failure. CONCLUSIONS The treatment of TASC C and D femoropopliteal lesions remains technically challenging. Our study supported the hypothesis that run-off is the most critical factor in determining the outcome of the procedure and that concomitant angioplasty of the tibial vessels might improve the patency of the covered stent. The CEVERO analysis could permit a real-time, objective estimation of the distal run-off using conventional angiographic images, and it might be employed as a tool in the intraprocedural decision-making process, but its clinical applicability should be evaluated on external validation cohorts. CLINICAL IMPACT The endovascular treatment of TASC C and D femoropopliteal lesions is technically challenging and run-off seems to be the most critical factor in determining the outcome. Concurrent angioplasty of the tibial vessels can create adequate run-off to avoid stent failure. The CEVERO analysis is a computerized estimation of run-off that might be a useful tool in the decision-making process.

Abstract
BACKGROUND Balloon angioplasty (BA), including drug-coated balloons (DCBs) and percutaneous transluminal angioplasty (PTA), has traditionally been used to treat femoral-popliteal lesions. However, in recent years, atherectomy (ATH) has been proposed as a complementary approach. To assess the effectiveness of ATH compared with BA alone in patients with femoral-popliteal artery lesions, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS We included RCTs that focused on patients with femoral-popliteal artery lesions and reported data on the use of ATH and BA therapy. Two reviewers conducted a literature search, refined the data, and assessed the risk of bias. RESULTS We included a total of 6 RCTs involving 399 patients with femoral-popliteal artery lesions. The use of ATH in combination with BA appeared to improve the patency rate at 12 months (odds ratio [OR]=2.04, 95% confidence interval [CI]=1.14-3.62). In addition, ATH with BA was associated with lower major amputation rates (MD=2.01, 95% CI=0.06-0.77, p=0.02) and a decreased likelihood of bailout stenting (OR=0.07, 95% CI=0.02-0.25, p=0.001). However, there were no statistically significant differences between the groups in terms of target lesion revascularization (TLR) at 12 months, major adverse cardiovascular events (MACEs), and distal embolization events. In addition, we performed subgroup analysis for different ATH devices and BA types. CONCLUSIONS Based on this meta-analysis, it can be concluded that the use of ATH in combination with BA is a safe and effective method for treating femoral-popliteal artery lesions. In addition, the patency rate at 1 year is superior to treatment with BA alone. Atherectomy also reduces the likelihood of amputation and bailout stenting. Clinicians should consider these findings when designing future RCTs and developing clinical practice guidelines. CLINICAL IMPACT This meta-analysis summarises a number of existing studies to advance understanding of the atherectomy devices and to reveal its potential. This new technique, when compared with drug coated balloon, shows the possibility of obtaining better clinical outcomes in femoro-popliteal lesions than drug-coated balloon alone, such as higher 12-month primary patency rates as shown in some studies. Currently, it is important to consider the appropriate technology applicable for individualised treatment. atherectomy devices seem to provide clinicians with additional options in clinical practice and to benefit patients in the future. This requires more high quality studies to explore the role and benefits of atherectomy devices in femoro-popliteal lesions.

Abstract
Acute type A aortic dissection (ATAAD) is a life-threatening emergency that is associated with major morbidity and mortality. Arterial dissections, particularly the brachiocephalic artery, can remain as a residual dissection after type A aortic dissection repair. We present a rare case of brachiocephalic artery dissection due to the clamping effect and the management of ATAAD patients. A 47-year-old male known for aortic aneurysm and uncontrolled hypertension presented with high blood pressure, unequal pulses, and a history of chest pain. A thoracic and abdominal aorta angiogram showed aneurysmal dilatation of the aortic root and ascending aorta with a peripheral linear filling defect shortly distal to the aortic root. The patient underwent the Bentall procedure, hemi-arch replacement, and patent ductus arteriosus closure. The brachiocephalic artery was clamped. The angiogram showed right common carotid occlusion. Endovascular intervention was made by balloon-mounted covered stent graft and kissing technique. The patient had a smooth post-procedure period without major events. Iatrogenic brachiocephalic artery dissection can occur during type A aortic dissection repair and is frequently affected by residual dissection. The decision of intervention versus conservative management is based on a patient's general condition.

Abstract
Below-the-knee (BTK) pseudoaneurysms that occur after endovascular therapy (EVT) and result in delayed rupture have rarely been reported. In this report, we present a rare case of an 86-year-old man with chronic limb-threatening ischemia who developed delayed rupture of an idiopathic pseudoaneurysm of the peroneal artery (PA) following EVT. The PA chronic total occlusion (CTO) was successfully crossed using a guidewire via an antegrade approach, however, subintimal crossing was confirmed by intravascular ultrasound. Balloon angioplasty was then performed using an appropriately sized balloon, resulting in successful recanalization of the PA CTO with minor dissection and no complications. Postoperatively, the patient's condition was stable until he suddenly complained of right calf pain 10 days after EVT. Computed tomography revealed a rupture of the PA pseudoaneurysm. Urgent angiography revealed two pseudoaneurysms, one saccular and the other spindle-shaped. The ruptured saccular aneurysm was successfully excluded through coil embolization and stent graft placement. To the best of our knowledge, this is the first reported case of delayed rupture of a BTK pseudoaneurysm following EVT. Balloon angioplasty in the subintimal space can lead to the formation of a pseudoaneurysm and its delayed rupture.

Abstract
BACKGROUND The adaptation of retrograde tibial-pedal access for peripheral angiogram and intervention is limited by the lack of operator experience and concern for small distal vessel injury. This study evaluates the safety of the retrograde tibial-pedal access for peripheral angiogram and intervention in patients with two vessel infra-popliteal artery chronic total occlusions, where the access point is the sole remaining non-occluded infra-popliteal artery. METHODS A retrospective analysis of 5687 consecutive patients who underwent peripheral angiograms by retrograde tibial-pedal access via the single remaining non-occluded infra-popliteal artery was performed. Patients who had retrograde tibial-pedal access at the sole remaining infra-popliteal artery confirmed by angiography were included. Clinical and ultrasound data of the accessed infra-popliteal vessel up to 6 months were collected. RESULTS The cohort consisted of 314 patients (152 males; mean age 77.9 years). At 6 months, access vessel complications occurred in 15 patients (4.8%). Access vessel occlusion occurred in 9 out of 314 patients (2.9%), arteriovenous fistula in 4 (1.3%), with spontaneous resolution in 2, pseudoaneurysm requiring thrombin injection in 2 (0.6%) and non-cardiovascular death in 1 (0.3%). No uncontrolled bleeding, procedure-related hospitalizations or limb amputations occurred. CONCLUSIONS Routine primary retrograde tibial-pedal access for lower extremity peripheral artery diagnostic angiography and intervention in patients with single infra-popliteal artery runoff can be safety performed in an outpatient setting with infrequent and manageable complications.

Abstract
Platelets play a critical role in blood clotting and the development of arterial blockages. Antiplatelet therapy is vital for preventing recurring events in conditions like coronary artery disease and strokes. However, there is a lack of comprehensive guidelines for using antiplatelet agents in elective neurosurgery. Continuing therapy during surgery poses a bleeding risk, while discontinuing it before surgery increases the risk of thrombosis. Discontinuation is recommended in neurosurgical settings but carries an elevated risk of ischemic events. Conversely, maintaining antithrombotic therapy may increase bleeding and the need for transfusions, leading to a poor prognosis. Artificial intelligence (AI) holds promise in making difficult decisions regarding antiplatelet therapy. This paper discusses current clinical guidelines and supported regimens for antiplatelet therapy in neurosurgery. It also explores methodologies like P2Y12 reaction units (PRU) monitoring and thromboelastography (TEG) mapping for monitoring the use of antiplatelet regimens as well as their limitations. The paper explores the potential of AI to overcome such limitations associated with PRU monitoring and TEG mapping. It highlights various studies in the field of cardiovascular and neuroendovascular surgery which use AI prediction models to forecast adverse outcomes such as ischemia and bleeding, offering assistance in decision-making for antiplatelet therapy. In addition, the use of AI to improve patient adherence to antiplatelet regimens is also considered. Overall, this research aims to provide insights into the use of antiplatelet therapy and the role of AI in optimizing treatment plans in neurosurgical settings.

Abstract
Background Autonomous navigation of catheters and guidewires in endovascular interventional surgery can decrease operation times, improve decision-making during surgery, and reduce operator radiation exposure while increasing access to treatment. Objective To determine from recent literature, through a systematic review, the impact, challenges, and opportunities artificial intelligence (AI) has for the autonomous navigation of catheters and guidewires for endovascular interventions. Methods PubMed and IEEEXplore databases were searched to identify reports of AI applied to autonomous navigation methods in endovascular interventional surgery. Eligibility criteria included studies investigating the use of AI in enabling the autonomous navigation of catheters/guidewires in endovascular interventions. Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), articles were assessed using Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2). PROSPERO: CRD42023392259. Results Four hundred and sixty-two studies fulfilled the search criteria, of which 14 studies were included for analysis. Reinforcement learning (RL) (9/14, 64%) and learning from expert demonstration (7/14, 50%) were used as data-driven models for autonomous navigation. These studies evaluated models on physical phantoms (10/14, 71%) and in-silico (4/14, 29%) models. Experiments within or around the blood vessels of the heart were reported by the majority of studies (10/14, 71%), while non-anatomical vessel platforms "idealized" for simple navigation were used in three studies (3/14, 21%), and the porcine liver venous system in one study. We observed that risk of bias and poor generalizability were present across studies. No procedures were performed on patients in any of the studies reviewed. Moreover, all studies were limited due to the lack of patient selection criteria, reference standards, and reproducibility, which resulted in a low level of evidence for clinical translation. Conclusion Despite the potential benefits of AI applied to autonomous navigation of endovascular interventions, the field is in an experimental proof-of-concept stage, with a technology readiness level of 3. We highlight that reference standards with well-identified performance metrics are crucial to allow for comparisons of data-driven algorithms proposed in the years to come. Systematic review registration identifier: CRD42023392259.

Abstract
INTRODUCTION Radial access is the standard of care for nearly all cardiac catheterization procedures. It improves patient satisfaction, reduces the length of stay, and is associated with fewer complications. However, few devices and tools are available for the treatment of peripheral arterial disease via a transradial approach (TRA). The S.M.A.R.T. RADIANZ Vascular Stent System is among the RADIANZ suite of products, which is aimed at expanding the portfolio of devices to treat peripheral arterial disease. AREAS COVERED In this Expert review, the following areas will be covered: (1) Current Landscape of peripheral vascular intervention (PVI) using TRA (2) Detailed description of the S.M.A.R.T. RADIANZ Vascular Stent System. (3) Ongoing clinical trials to evaluate safety of this approach. (4) Future directions and current regulatory status. EXPERT OPINION TRA for PVI is a promising approach. It holds the possibility of substantially improving the care of patients with peripheral arterial disease (PAD). Numerous challenges must be overcome to realize the full potential of a radial-to-peripheral (RTP) approach. The length of devices and the small sheath size are the main constraints of this approach. The results of the ongoing RADIANCY trial will demonstrate the safety, in selected patients, of the RADIANZ suite of products.

Abstract
Background and Aims Intracranial arterial dissections commonly involve the vertebrobasilar system leading to subarachnoid hemorrhage (SAH) or cerebral infarction attributable to a dissecting aneurysm of the vessel or occlusion of the lumen depending on the depth of dissection. However, isolated posterior cerebral artery dissections (PCADs) are rare and sparsely reported in the literature. Methodology A retrospective multicentric observational study was carried out after collecting data from 14 patients admitted with PCAD in three hospitals of Kolkata, Jaipur, and Patna within the period of July 2021 to June 2022. Results The median age of the population was 48.5 years, and 64.28% were females. SAH was the most common presentation with dissecting aneurysms in all patients barring one, who presented with a left occipital infarct consequent to ipsilateral PCAD. Among the 14 patients, three patients denied endovascular intervention and were lost to follow-up; one patient with an occipital infarct and another patient with a dissecting left P3 aneurysm, which underwent spontaneous thrombosis, were managed conservatively. Among the nine patients scheduled for endovascular coiling, one patient succumbed before intervention and one patient succumbed to sepsis in the postoperative period. A complete recovery was noted in six patients, whereas residual neurodeficits were present in three patients. Among the six patients who had an uneventful recovery at the end of 3 months, five patients had an endovascular intervention. Conclusion PCAD may present with large-scale neurodeficits and is associated with high morbidity and mortality, hence necessitating prompt management. Conservative management is preferable for consequent infarcts, whereas endovascular management is desirable in cases of dissecting aneurysms, which usually tend to have a favorable outcome if intervened early.

Abstract
Below-the-knee intervention of chronic limb-threatening ischemia is an area of increasing interest. Due to lower morbidity and possibly better clinical outcomes, endovascular techniques have become increasingly important in this patient population many of who have limited surgical options. This article serves as a review of existing stent and scaffolding devices utilized for infrapopliteal disease. The authors will additionally discuss current indications and review studies that are investigating novel materials used in treating infrapopliteal arterial disease.

Abstract
BACKGROUND Cavernous sinus dural arteriovenous fistula (CSDAVF) is a rare condition that radiologists would encounter in their careers. We aim to describe the clinical and radiological characteristics of this condition, and to provide a management workflow. METHODS In our retrospective study, we studied 27 patients with CSDAVF from January 2007 to August 2020. Patients with direct cavernous sinus AVFs and patients with incomplete date were excluded. Clinical and radiological data were collected and analyzed. RESULTS Fourteen patients were conservatively treated with spontaneous resolution while 13 patients had endovascular intervention performed. In the intervention group, seven patients had intra-cranial reflux seen on radiological imaging and six patients had clinical deterioration, hence requiring intervention. Clinically, among our patients, 21 had proptosis, 20 had conjunctiva hyperaemia, 18 had extraocular movement limitation, 13 had raised intraocular pressure, 11 had chemosis, ten had ocular pain, nine had ocular bruit, eight had headache and six had worsening visual acuity. Radiologically, a concurrence was seen between superior ophthalmic vein thrombosis and spontaneous resolution of the CSDAVF, as compared to those who underwent intervention. A paradoxical increase of ocular symptoms was seen despite a decrease of flow or stagnation of contrast in radiological imaging of CSDAVF. CONCLUSIONS In our study, 52% of CSDAVF closed spontaneously. As deterioration of ocular symptoms in patients with CSDAVF might also reflect spontaneous progressive occlusion, it warrants dynamic vascular imaging to check the status of venous outflow. Patients with CSDAVF with corticovenous reflux or deterioration of visual acuity need more urgent (endovascular) treatment.

Abstract
We aimed to review the feasibility and safe use of the percutaneous axillary artery (AxA, 100 patients) approach for endovascular repair (ER) of thoraco-abdominal aortic aneurysms (TAAA, 90 patients) using fenestrated, branched, and chimney stent grafts and other complex endovascular procedures (10 patients) necessitating AxA access. Percutaneous puncture of the AxA in its third segment was performed using sheaths sized between 6 to 14F. For closing puncture sites greater than 8F, two Perclose ProGlide percutaneous vascular closure devices (PVCDs) (Abbott Vascular, Santa Clara, CA, USA) were deployed in the pre-close technique. The median maximum diameter of the AxA in the third segment was 7.27 mm (range 4.50-10.80). Device success, defined as successful hemostasis by PVCD, was reported in 92 patients (92.0%). As recently reported results in the first 40 patients suggested that adverse events, including vessel stenosis or occlusion, occurred only in cases with a diameter of the AxA < 5 mm, in all subsequent 60 cases AxA access was restricted to a vessel diameter ≥ 5 mm. In this late group, no hemodynamic impairment of the AxA occurred except in six early cases below this diameter threshold, all of which could be repaired by endovascular measures. Overall mortality at 30 days was 8%. In conclusion, percutaneous approach of the AxA in its third segment is feasible and represents a safe alternative access to open access for complex endovascular aorto-iliac procedures. Complications are rare, especially if the maximum diameter of the access vessel (AxA) is ≥5 mm.

Abstract
A significant challenge regarding the treatment of aneurysms is the variability in morphology and analysis of abnormal flow. With conventional DSA, low frame rates limit the flow information available to clinicians at the time of the vascular intervention. With 1000 fps High-Speed Angiography (HSA), high frame rates enable flow details to be better resolved for endovascular interventional guidance. The purpose of this work is to demonstrate how 1000 fps biplane-HSA can be used to differentiate flow features, such as vortex formation and endoleaks, amongst patient-specific internal carotid artery aneurysm phantoms pre- and post-endovascular intervention using an in-vitro flow setup. The aneurysm phantoms were attached to a flow loop configured to a carotid waveform, with automated injections of contrast media. Simultaneous Biplane High-Speed Angiographic (SB- HSA) acquisitions were obtained at 1000 fps using two photon-counting detectors with the respective aneurysm and inflow/ outflow vasculature in the FOV. After x-rays were turned on, the detector acquisitions occurred simultaneously, during which iodine contrast was injected at a continuous rate. A pipeline stent was then deployed to divert flow from the aneurysm, and image sequences were once again acquired using the same parameters. Optical Flow, an algorithm that calculates velocity based on spatial-temporal intensity changes between pixels, was used to derive velocity distributions from HSA image sequences. Both the image sequences and velocity distributions indicate detailed changes in flow features amongst the aneurysms before and after deployment of the interventional device. SB-HSA can provide detailed flow analysis, including streamline and velocity changes, which may be beneficial for interventional guidance.

Abstract
BACKGROUND Adequate antithrombotic therapy is essential to prevent thrombus formation during percutaneous endovascular interventions (PVI). We hypothesize that interventions for non-complex lesions of iliac arteries do not need procedural anticoagulation if patients are under dual antiplatelet therapy (DAPT). METHODS Iliac PVIs performed without procedural anticoagulation were retrospectively screened between 2017 and 2021. Baseline characteristics of patients, in-hospital events and 30-day follow-ups were obtained from hospital records. Each PVI was reviewed for procedural details. Primary safety outcome was thromboembolic events during intervention. Secondary safety outcome was adverse vascular events at 30-day follow-up. Procedure times of iliac interventions were compared to peripheral angiography procedures of patients with similar demographic characteristics. RESULTS We identified 108 iliac interventions without procedural anticoagulation, median age of 62 (interquartile range 56-68) years, 9 (8.3%) females. Median lesion length was 30 (19-50) mm. We observed a thrombotic finding in 4 (3.7%) procedures. Visible luminal thrombus was observed in 2 (1.9%) and introducer sheath thrombosis in 2 procedures (1.9%), all of which were in patients with in-stent lesions. No distal embolization was observed in final angiography of these procedures. At 30-day follow-up, acute limb ischemia was not observed and clinically driven target vessel revascularization was not required in any of the patients. Procedure time of iliac interventions was similar to that of lower extremity diagnostic procedures [18 (11-24) vs 18 (14-24) min, respectively, P = .364]. No major bleeding event was observed after iliac interventions. CONCLUSION Non-complex lesions of iliac arteries can be managed within a time frame similar to that of lower extremity diagnostic procedures. These interventions can be performed safely without procedural anticoagulation, provided patient receives DAPT. Intervention of in-stent lesions should ideally be avoided without procedural anticoagulation.

Abstract
Background Internal carotid artery pseudoaneurysm (PSA) is a serious complication after radiotherapy for nasopharyngeal carcinoma, and once it ruptures and bleeds, it will seriously affect the patient's survival and prognosis. However, because of its relatively low incidence, many medical institutions lack experience in managing this type of emergency. Case information In this case report, we described two cases suffered ruptured internal carotid artery PSA after radiotherapy for nasopharyngeal carcinoma, including their history, diagnosis, and treatment. Both cases underwent emergency endovascular interventions, one of which with long-term healing after embolization of the PSA, and the other one with re-bleeding after embolization and was eventually stopped by embolization of the parent artery. Ultimately, both cases received timely and effective treatment. Conclusion This case report detailed the diagnosis and treatment course of internal carotid artery PSA after radiotherapy for nasopharyngeal carcinoma, which enhanced the understanding of this emergency, and provided valuable information and experience for the treatment strategy of similar PSA on the internal carotid artery.

Abstract
BACKGROUND Despite advances in endovascular techniques to treat acute limb ischemia (ALI), evaluation of clinical outcomes for revascularization remains challenging, especially the accurate quantification of post-endovascular limb perfusion. This study aimed to investigate the accuracy and value of 2D perfusion angiography to evaluate endovascular intervention for ALI. METHODS A total of 47 patients with ALI were retrospectively analyzed. The transcutaneous oxygen partial pressure (TcPO2) was obtained using laser Doppler blood perfusion monitoring. The ankle-brachial index (ABI) and angiographic images were obtained before and after endovascular intervention. iFlow imaging was used to obtain color-coded images. Regions of interest (ROIs) at the femoral head, knee joint, and ankle joint were selected to obtain the time to peak (TTP). The differences in the TTP between the knee and femoral head regions (TTP difference in the knee area) and between the ankle and knee regions (TTP difference in the ankle area) were observed. The TTP, ABI, and TcPO2 between the complete response (CR), partial response (PR), no response (NR), and amputation (AM) groups were compared. The correlation between TTP changes in the ankle area (ΔTTP) and changes in ABI (ΔABI)/changes in TcPO2 (ΔTcPO2) was analyzed. RESULTS There was a significant increase in both TcPO2 and ABI compared with the pre-intervention values (27.75 ± 5.32 vs 40.92 ± 4.62, and 0.35 ± 0.16 vs 0.79 ± 0.15, respectively, all p < 0.01). The post-intervention TTP differences in the knee areas (5.12 ± 2.45 s) and ankle areas (6.93 ± 4.37 s) were significantly faster than pre-intervention TTP differences (7.03 ± 2.57 s and 10.66 ± 4.07 s, respectively, all p < 0.05). The post-operative TTP in the ankle area, post-operative TTP difference in the ankle area, and ΔTTP in the AM group were higher than the values in the CR and PR groups. The ΔTTP demonstrated strong correlation with ΔABI (r = -0.722, p < 0.01) and ΔTcPO2 (r = -0.734, p < 0.01). CONCLUSIONS 2D perfusion angiography with enhanced visual and quantitative analysis exhibits great potential to evaluate the efficacy of endovascular intervention, and provides a quantitative and sensitive tool to evaluate post-endovascular limb perfusion for ALI patients.

Abstract
Background Thrombotic popliteal artery aneurysm (PAA) with acute lower limb ischemia (ALI) is a serious disease leading to amputation. The choice of emergency procedures is not clearly defined, and the difference in therapeutic efficiency between open surgery and endovascular intervention is still unclear. Method We conducted a comprehensive search through PubMed, Wiley Online Library and ScienceDirect. According to the predefined inclusion and exclusion criteria, eligible articles were screened out, and all relevant data were extracted for further analysis. Our study was designed and developed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guideline. We critically assessed all included articles by Joanna Briggs Institute (JBI) Critical Appraisal Checklists and the Methodological Index for Non-Randomized Studies (MINORS). Result A total of 29 articles (1338 patients/1387 limbs) were included in the study. After a 1-year follow-up, the primary patency rate of the open surgery group was significantly lower than that of the endovascular intervention group (72.65 vs. 81.46%, P = 0.004), but without significant difference in the secondary patency rate (86.19 vs. 86.86%, P = 0.825). The limb salvage rate of the open surgery group was also significantly lower (83.07 vs. 98.25%, P < 0.001). After the 2-year follow-up, the primary patency rate of the open surgery group was still significantly lower (48.57 vs. 59.90%, P = 0.021). Conclusion The outcome of endovascular intervention was better than that of open surgery especially in the 1-year limb salvage rate and primary patency rate at the 1-year and 2-year follow-ups.

Abstract
PURPOSE To investigate the demographics, clinical features, radiologic measurement, treatment, and outcomes of symptomatic spontaneous isolated superior mesenteric artery dissection (SISMAD) according to computed tomography (CT) classification. METHODS This retrospective study included 201 patients diagnosed with symptomatic SISMAD from November 2014 to December 2020. Symptomatic spontaneous isolated superior mesenteric artery dissection was categorized into four types based on CT images by Yun's angiographic classification. Their clinical characteristics, images features, treatment methods, and radiological outcomes were comparatively analyzed by CT angiographic types. RESULTS SISMADs were categorized into type I (13.9%) patent false lumen (FL) with both entry and re-entry; type IIa (37.3%), blind pouch of FL; type IIb (43.3%), thrombosed FL; and type III (5.5%), and the occlusion of superior mesenteric artery (SMA). Type IIb, the most common SISMAD, showed the largest true lumen (TL) residual diameter and the lowest percentage of TL stenosis. Type III positioned most proximally to SMA origin and had the maximum dissection length. Symptomatic spontaneous isolated superior mesenteric artery dissections underwent conservative (75.1%), endovascular (22.4%), and surgical (2.5%) treatment. Conservative treatment was more frequent in type I (85.7%) and type IIb (83.9%) than in type IIa (65.3%) and type III (45.5%). Endovascular intervention was more commonly utilized in type IIa (32.0%) and type III (36.4%) than in type I (14.3%) and type IIb (14.9%). Conservative patients achieved FL vanishment/shrinkage (57.8%), stabilization (26.6%), and enlargement (15.6%). After conservative treatment, type I showed angiographic FL stabilization; type IIa achieved FL shrinkage (48.1%), stabilization (22.2%), and enlargement (29.6%); type IIb exhibited FL vanishment/shrinkage (92.0%) and enlargement (8.0%). Cumulative rate of stent patency was 92.3% during 6-year follow-up. CONCLUSIONS Conservative management with close follow-up is initially provided especially for types I and IIb. Morphological stabilization is more frequent in type I of patent FL with entry and re-entry. False lumen vanishment or shrinkage was more likely to occur in type IIb due to the thrombus absorption. Endovascular intervention has excellent long-term in-stent patency and is predominantly utilized in types IIa and III. Blood flow sustained into a blind-ending FL causes the TL compression and stenosis in type IIa. Type III with the occlusion of SMA has the high risk of bowel ischemia. CLINICAL IMPACT According to Yun's angiographic classification of spontaneous isolated superior mesenteric artery dissection (SISMAD), type I (13.9%) has patent true and false lumen and the morphological pattern is maintained stable; type IIa (37.3%) possesses a patent blind-ending false lumen which might shrink, remain unchanged, or enlarge; and endovascular intervention is suggested when conservative treatment failed; type IIb (43.3%) recovers spontaneously due to the absorption of false lumen thrombus and conservative treatment is preferentially considered; type III (5.5%) with the occlusion of main trunk carries a high risk of bowel necrosis, early endovascular intervention is proposed, and open surgery might be necessary.

Abstract
BACKGROUND Neurofibromatosis type 1 (NF1) is caused by mutations in the NF1 gene on the long arm of chromosome 17, which affects the skin, nervous system, eyes, and skeleton system. Vertebral arteriovenous fistula (AVF) associated with neurofibromatosis type I (NF-1) is rare. CASE PRESENTATION We report a 31-year-old postpartum woman with NF1 with vertebral arteriovenous fistulae (AVFs). She presented to our hospital because of neck pain, intracranial hypotension headache, and right upper limb weakness. She had a family history of NF1. After endovascular intervention, the AVF disappeared. However, a new aneurysm appeared on the right vertebral artery V5 dissection after 6 months of follow-up. CONCLUSIONS The presence of NF1 in patients who present with neurologic signs should prompt further angiography. Awareness of the coexistence between NF1 and AVF or aneurysm is crucial to avoiding diagnostic delays. Endovascular occlusion of VV-AVF in NF-1 patients is effective and safe.

Abstract
INTRODUCTION Image-guided endovascular interventions, performed using the insertion and navigation of catheters through the vasculature, have been increasing in number over the years, as minimally invasive procedures continue to replace invasive surgical procedures. Such endovascular interventions are almost exclusively performed under x-ray fluoroscopy, which has the best spatial and temporal resolution of all clinical imaging modalities. Magnetic resonance imaging (MRI) offers unique advantages and could be an attractive alternative to conventional x-ray guidance, but also brings with it distinctive challenges. AREAS COVERED In this review, the benefits and limitations of MRI-guided endovascular interventions are addressed, systems and devices for guiding such interventions are summarized, and clinical applications are discussed. EXPERT OPINION MRI-guided endovascular interventions are still relatively new to the interventional radiology field, since significant technical hurdles remain to justify significant costs and demonstrate safety, design, and robustness. Clinical applications of MRI-guided interventions are promising but their full potential may not be realized until proper tools designed to function in the MRI environment are available. Translational research and further preclinical studies are needed before MRI-guided interventions will be practical in a clinical interventional setting.

Abstract
OBJECTIVES The OPEN study evaluated the safety and efficacy of the S.M.A.R.T.® Flex Vascular Stent System in patients with femoropopliteal arterial disease. BACKGROUND Long-term data on endovascular treatments of femoropopliteal arterial disease are required to establish the repair durability. METHODS The OPEN study was a multicenter, single-arm, prospective study comparing primary safety and efficacy outcomes to performance goals (PG) developed for bare nitinol stents. Patients with symptoms due to a single, ≤180 mm length, de novo femoropopliteal arterial lesion with >70% stenosis were enrolled were enrolled and followed for 36 months. Subjects with lesions ≤150 mm served as the initial comparison cohort for the PG (other cohorts were analyzed if the PG was met). RESULTS 257 subjects with lesions ≤180 mm were enrolled. The mean lesion length was 71 ± 46, and 52.5% had severe claudication. The primary safety endpoint (freedom from all-cause death, index limb amputation, and target lesion revascularization [TLR] through 30 days) was met in 98.8% (96.5%, 99.6%) of subjects in the comparison cohort, meeting the PG (88.0%). The primary efficacy endpoint (comparison cohort vessel patency at 12 months) was 68.4% (61.1%, 74.8%), where the lower limit of the 95% confidence interval did not meet the 66.0% PG. Freedom from TLR in the per-protocol cohort at 12-, 24-, 36-month was 84.7%, 74.6%, and 72.8%, respectively. The 24-month stent fracture rate was 4.3%, with no new fractures identified at 36 months. CONCLUSION The results show promising long-term safety and effectiveness for the S.M.A.R.T.® Flex Vascular Stent System in patients with femoropopliteal arterial disease.

Abstract
OBJECTIVE Fasciotomy can increase the mobility of the superficial femoral artery and decrease the incidence of stent fractures. This study aimed to compare the long-term patency of drug-eluting nitinol stents with and without fasciotomy in patients with prolonged SFA occlusions. METHODS A randomized clinical trial was conducted in 60 (1:1) patients with long femoropopliteal steno-occlusive lesions more than 200 mm. Patients in group 1 (Zilver) underwent recanalization of femoropopliteal artery occlusion with stenting. In group 2 (ZilverFas), the femoropopliteal occlusion was recanalized with stenting and fasciotomy of Gunter's canal. The follow-up assessment of the patency took place after 6, 12 months. RESULTS 12-month primary patency in Zilver and ZilverFas groups was 51% and 80%, respectively (p = 0.02). The freedom from target revascularization (TLR) in Zilver and ZilverFas groups was 50% and 76%, respectively (p = 0.04). At one-year, primary-assisted and secondary patency for the ZilverFas and Zilver groups were 83% versus 62% (p = 0.07), 86% versus 65% (p = 0.05), respectively. In Zilver and ZilverFas groups, the number of stents fractures was 14 and 7, respectively (p = 0.05). The multivariables Cox regression indicated that the stent fracture and diabetes mellitus were the independent predictors of restenosis and reocclusion. Fasciotomy reduced the risk of reocclusion and restenosis by 2.94 times. CONCLUSIONS Our study has shown that a decompressing the stented segment with fasciotomy significantly improves the patency of the femoropopliteal segment and significantly reduces the number and severity of stent fractures.

Abstract
Emerging innovations have led to the development of tools and techniques to perform mechanical aspiration of right-sided endocarditis vegetations. However, blood loss during aspiration, the need for veno-veno bypass, and nonsteerable catheters have limited expansion of these treatment options to more patients. We present a case of pacemaker lead endocarditis treated with the Inari mechanical aspiration system utilizing the new T20 curved catheter (Inari Medical).

Abstract
BACKGROUND Occlusion of the unilateral P1 segment can result in bilateral paramedian thalamic infarction in patients with anatomical variants of the bilateral paramedian thalamic artery arising from a single P1 segment. Despite the life-threatening presentation of bilateral paramedian thalamic stroke, timely diagnosis is often challenging. OBSERVATIONS The authors herein describe 3 patients treated with endovascular intervention for occlusion of the unilateral P1 segment wherein the bilateral paramedian thalamic arteries arose. All patients were admitted to the authors' emergency department with sudden-onset coma and respiratory distress; however, initial computed tomography was unremarkable. Despite suspicion of basilar artery occlusion, vertebral and carotid angiography revealed occlusion of the unilateral P1 segment. All patients were successfully treated with endovascular intervention. Overall, 2 patients had favorable outcomes (modified Rankin scale [mRS] scores of 0 and 1), whereas in 1 patient, the mRS score reached a baseline score of 3. LESSONS In patients with the variant of the bilateral paramedian thalamic artery arising from a single P1 segment, occlusion of the unilateral P1 segment can be life threatening; nevertheless, timely endovascular treatment is effective. Carotid and vertebral angiography, rather than magnetic resonance or computed tomography angiography, is useful for immediate and reliable diagnosis of the relatively small vascular lesions.

Abstract
OBJECTIVE In-stent restenosis (ISR) remains a challenge in the treatment of vertebral artery V1 segment stenosis. The aim of this meta-analysis is to identify the risk factors of ISR. METHODS Studies eligible for inclusion criteria were found in PubMed, Embase, and Cochrane Library databases. Data related to risk factors of ISR were extracted from the included studies, and pooled analysis was performed when data of the same factor were available in ≥2 studies. Dichotomous outcomes were analyzed with odds ratios (OR) and continuous outcomes were analyzed with a weighted mean difference (WMD). The Stata 14.0 program was used for the meta-analysis. RESULTS A total of 11 studies involving 1356 patients were included in our analysis. Pooled analyses showed that younger age (p = 0.01; WMD= -1.958; 95% confidence interval [CI], -3.453 to -0.463) and V1 tortuosity (p = 0.004; OR = 4.145; 95% CI, 1.56-11.012) significantly associated with higher risk of ISR in V1 segment stenting. While bare-metal stents, stent diameter and length, diabetes mellitus, coronary artery disease, and smoking were not found to increase ISR rates. CONCLUSIONS This meta-analysis showed that young age and V1 tortuosity increase the ISR rates after vertebral V1 segment stenting.

Abstract
There is no consensus on the best treatment modality for acute distal embolization complications during endovascular interventions for peripheral arterial diseases. We report on 3 patients who underwent mechanical embolectomy using a distal embolic protection device (EPD). All patients showed angiographic evidence of distal embolism, which occurred during lower extremity limb salvage endovascular procedures. After embolectomy, all had complete recanalization of the involved vessel on completion angiogram, and none had any device-related complications or adverse outcomes from the embolization. This initial experience suggests that EPD can be used for both the prevention and treatment of intraoperative distal embolization during endovascular intervention of lower extremity arterial disease.

Abstract
RATIONALE Currently endovascular treatments are commonly utilized to treat postpancreaticoduodenectomy hemorrhage. However, when endovascular procedure went wrong, open surgery with ligation of the culprit vessels would be the most common salvage method. With Modified Viabahn Open Revascularization TEChnique (VORTEC), we can try to rescue the vessel without sacrificing it by introduction of another endovascular stent under direct method. PATIENT CONCERNS A 76-year-old man with stage IIIA ampulla vater adenocarcinoma underwent pancreaticoduodenectomy and experience pancreatic leak complicated with postpancreaticoduodenectomy hemorrhage. DIAGNOSIS Emergent angiography revealed extravasation from proper hepatic artery. INTERVENTIONS A 6 mm Viabahn stent was deployed but no distal runoff. Operation was shifted to emergent laparotomy and revealed intimal dissection of hepatic artery. Modified VORTEC was performed with guidewire redirected to true lumen and another stent was deployed under direct vision. OUTCOMES Patient's hepatic artery was preserved and with no consequent liver failure. LESSON Modified VORTEC method could be used as salvage strategy for artery dissection after initial endovascular treatment failed.

Abstract
BACKGROUND Use of endovascular intervention (EI) for blunt cerebrovascular injury (BCVI) is without consensus guidelines. Rates of EI use and radiographic characteristics of BCVI undergoing EI nationally are unknown. METHODS A post-hoc analysis of a prospective, observational study at 16 U.S. trauma centers from 2018 to 2020 was conducted. Internal carotid artery (ICA) BCVI was included. The primary outcome was EI use. Multivariable logistic regression was performed for predictors of EI use. RESULTS From 332 ICA BCVI included, 21 (6.3%) underwent EI. 0/145 (0%) grade 1, 8/101 (7.9%) grade 2, 12/51 (23.5%) grade 3, and 1/20 (5.0%) grade 4 ICA BCVI underwent EI. Stroke occurred in 6/21 (28.6%) ICA BCVI undergoing EI and in 33/311 (10.6%) not undergoing EI (P = .03), with all strokes with EI use occurring prior to or at the same time as EI. Percentage of luminal stenosis (37.75 vs 20.29%, P = .01) and median pseudoaneurysm size (9.00 mm vs 3.00 mm, P = .01) were greater in ICA BCVI undergoing EI. On logistic regression, only pseudoaneurysm size was associated with EI (odds ratio 1.205, 95% CI 1.035-1.404, P = .02). Of the 8 grade 2 ICA BCVI undergoing EI, 3/8 were grade 2 and 5/8 were grade 3 prior to EI. Of the 12 grade 3 ICA BCVI undergoing EI, 11/12 were grade 3 and 1/12 was a grade 2 ICA BCVI prior to EI. DISCUSSION Pseudoaneurysm size is associated with use of EI for ICA BCVI. Stroke is more common in ICA BCVI with EI but did not occur after EI use.

Abstract
OBJECTIVES The aim of this study was to investigate whether the addition of intravascular ultrasound (IVUS) guidance during femoropopliteal artery interventions reduced the rate of binary restenosis within 12 months compared with angiographic guidance alone. BACKGROUND IVUS is more accurate than angiography for assessment of vessel size and disease severity. Low-level studies suggest that the use of IVUS in femoropopliteal endovascular interventions improves outcomes, but currently, no level 1 evidence exists. METHODS This was a prospective single-center trial of 150 patients undergoing femoropopliteal endovascular intervention, randomized (1:1) to guidance by angiography or angiography and IVUS. The primary outcome measure was freedom from binary restenosis, on duplex ultrasound, within 12 months. Secondary outcomes included clinically driven target lesion revascularization, disagreements in imaging findings between modalities, and changes in treatment caused by IVUS. RESULTS Freedom from binary restenosis at 12 months was significantly higher in the IVUS group (72.4% vs 55.4%; P = 0.008). There was no significant difference between groups for clinically directed target lesion revascularization (84.2% and 82.4%; P = 0.776). Mean vessel diameter was significantly larger with IVUS (5.60 mm vs 5.10 mm; P < 0.001). A change in treatment occurred caused by IVUS in 79% of cases. Binary restenosis was lower in the IVUS group for cases treated with drug-coated balloons (9.1% vs 37.5%; P = 0.001). CONCLUSIONS The use of IVUS resulted in a significant reduction in the rate of restenosis after endovascular intervention. This is the first randomized controlled trial to demonstrate that IVUS improves outcomes in femoropopliteal interventions. This benefit may primarily relate to cases treated with drug-coated balloons.

BACKGROUND Air embolism (AE), especially when affecting the brain, is an underrated and potentially life-threatening complication in various endovascular interventions. This study aims to investigate experimental AEs using a new model to generate micro air bubbles (MAB), to assess the impact of a catheter on these MAB, and to demonstrate the applicability of this model in vivo. MATERIALS AND METHODS Micro air bubbles were created using a system based on microfluidic channels. The MAB were detected and analyzed automatically. Micro air bubbles, with a target size of 85 µm, were generated and injected through a microcatheter. The MAB diameters proximal and distal to the catheter were assessed and compared. In a subsequent in vivo application, 2000 MAB were injected into the aorta (at the aortic valve) and into the common carotid artery (CCA) of a rat, respectively, using a microcatheter, resembling AE occurring during cardiovascular interventions. RESULTS Micro air bubbles with a highly calibrated size could be successfully generated (median: 85.5 µm, SD 1.9 µm). After passage of the microcatheter, the MAB were similar in diameter (median: 86.6 µm) but at a lower number (60.1% of the injected MAB) and a substantially higher scattering of diameters (SD 29.6 µm). In vivo injection of MAB into the aorta resulted in cerebral microinfarctions in both hemispheres, whereas injection into the CCA caused exclusively ipsilateral microinfarctions. CONCLUSION Using this new AE model, MAB can be generated precisely and reproducibly, resulting in cerebral microinfarctions. This model is feasible for further studies on the pathophysiology and prevention of AE in cardiovascular procedures.

Abstract
OBJECTIVES To understand the prevalence of malnutrition and its association with chronic limb-threatening ischemia (CLTI) outcomes; to clarify the differential impact of revascularization methods on outcomes; to assess the ability of the CLTI Frailty Risk Score (CLTI-FRS) to predict adverse events in patients hospitalized with CLTI. BACKGROUND Despite advances in the management of CLTI, a majority still undergo major amputation, and a minority heal within 6 months. There is a lack of validated assessment tools for the identification and management of frailty and malnutrition in these patients. METHODS Using the National Inpatient Sample from January 2012 to September 2015, we identified all patients with CLTI using International Classification of Diseases Ninth Edition Clinical Modification codes. The cohort was divided into three groups according to nutritional status. Multivariable regression analysis was used to analyze the interaction between malnutrition and outcomes of interest. RESULTS Of 1,414,080 CLTI-related hospitalizations, 163,835 (11.6%) were malnourished, 332,855 (23.5%) patients were frail, 917,390 (64.9%) were well-nourished. In-hospital mortality, major amputation, the average length of stay, and hospital costs were highest among malnourished or frail patients and lowest in well-nourished patients (p < 0.001). Malnourished and frail patients were observed to have lower rates of mortality with endovascular revascularization as compared to surgical (adjusted odds ratios: 0.675 [0.533-0.854; p = 0.001]). CONCLUSION Many patients with CLTI are malnourished or frail, and this is associated with mortality and amputation. Both malnourished and frail patients were observed to have a mortality benefit with a less invasive approach to revascularization. Better assessment of nutritional and frailty status of CLTI patients may guide therapy and help prevent amputation and death.

Abstract
Introduction Arteriovenous fistulas (AVFs) are the preferred route of hemodialysis in end-stage renal disease. However, recurrent patency loss is an obstacle in long-term maintenance. Endovascular treatments may provide a durable option for prolongation of patency in AVFs. Methods Retrospective observational study was done on 46 patients with AVF for hemodialysis in the Department of Diagnostic and Interventional Radiology for a period of 1 year from September 2020 to August 2021. The characters of dysfunctional fistulas and results of various interventional procedures were assessed for technical and clinical success rates. Short-term follow-up records of patients were assessed for post-intervention primary patency (PIPP) and post-intervention assisted primary patency (PIAPP) of various procedures. Results The most successful outcomes post intervention were seen in radio-cephalic fistulas formed more than 1 year ago with juxta-anastomotic narrowing. The overall technical success rate was 89.13% with a PIPP of 78.26% and a PIAPP of 82.60% at 3 months. PTA had better technical success rates (88.23%) as compared to dysfunctional segments with thrombosis that underwent angioplasty and thromboaspiration (84.2%). Central venous stenosis undergoing PTA and stenting had a 100% success rate. At 3 months follow-up, PIPP was better among the angioplasty plus thromboaspiration group (73.7%), while PIAPP rate was better in the angioplasty subgroup at 82.35%. Conclusion Endovascular intervention is the first-line treatment in dysfunctional AVFs attributable to the multitude of options available, all of which have comparable outcomes, high success rates, and notable short-term patency.

Abstract
The authors report hybrid treatment of a patient with angina pectoris class II, multiple previous reconstructive interventions on the aortofemoral segment and chronic ischemia of the left lower limb stage IV and concomitant COVID-19. Coronary angiography was performed after regression of infectious disease under antiviral therapy. Occlusion of the left anterior descending artery was observed that required LAD stenting. On the next day, hybrid revascularization of the lower extremities was implemented: thrombectomy and endarterectomy from the branch of the aorto-femoral bypass graft and deep femoral artery at the first stage, stenting of the orifice of proximal branch of aorto-femoral bypass graft at the second stage, endarterectomy from superficial femoral artery, recanalization and stenting of superficial femoral artery and popliteal artery at the third stage and prosthetic- femoral bypass with autologous vein at the fourth stage. Postoperative angiography revealed patent stents and no residual stenoses. The choice in favor of these procedures and step-by-step approach has been substantiated. The authors emphasized effectiveness and safety of this treatment strategy.

Abstract
Splenic artery aneurysm and splenic artery pseudoaneurysm are rare vascular pathologies. The splenic artery represents the third most common site for intra-abdominal aneurysms. In contrast with true splenic artery aneurysm, splenic artery pseudoaneurysm is typically symptomatic, presenting with a range of symptoms, from abdominal pain to hemodynamic instability due to rupture. However, gastrointestinal hemorrhage is an uncommon complication of splenic artery pseudoaneurysm. We report a case of acute upper gastrointestinal hemorrhage due to splenic artery pseudoaneurysm rupture. The patient was successfully treated by endovascular intervention.

Abstract
Dural arteriovenous fistulas (dAVF) are rare, acquired intracranial arteriovenous malformations consisting of a pathological shunt located within the intracranial dura matter. The etiology of dAVFs remains unclear, but current thought suggests that these lesions are associated with thrombosis of the dural sinuses and other intracranial veins. dAVF’s with severe symptomatology or high-risk angioarchitecture should be treated without delay, and endovascular repair is generally accepted as the first-line treatment. Both transarterial and transvenous approaches can be used to cure dAVFs. Surgery and stereotactic radiosurgery may also be used when endovascular approaches are unsuccessful or not feasible. Some studies, however, have shown that surgery for dAVFs in the anterior cranial fossa is preferred over the endovascular approach. Due to the proximity of some dAVFs to the orbit, endovascular embolization of the dAVF carries a higher risk of complications, primarily due to the formation of dangerous extracranial or intracranial anastomoses. We present the case of a 64-year-old male with an incidentally discovered Borden type III dAVF arising from the anterior branches of the middle meningeal artery and draining into the middle cerebral vein. Due to the location of his dAVF, craniotomy was selected for ligation of the fistula. The procedure went without complication. A catheter angiogram of the brain one month after surgery showed an absence of flow through the arteriovenous fistula and a middle meningeal artery that had returned to its normal caliber.

Abstract
Background Acute mesenteric ischemia (AMI) is a vascular emergency with a quite low incidence, but it is associated with disproportionately more severe morbidity and mortality. The aim of this study was to assess the current trend in the treatment of AMI and to see if endovascular intervention is an effective treatment modality in the selected group of patients. Methods A retrospective review of patients admitted with AMI between 2007 and 2018 was performed. Outcome measures were length of stay (LOS) at hospital and intensive care unit (ICU), and post-treatment mortality. Results A total of 98 patients with AMI were admitted during the study period. Patients undergoing endovascular treatment compared with surgery were younger (62.9 ± 13.7 years vs. 69.5 ± 12.8 years; p = 0.01). Shorter LOS in hospital and ICU was observed for those treated with endovascular approach (6.8 ± 3.4 and 3.25 ± 0.5 days) compared to the surgical group (25 ± 8.6 and 12.8 ± 26.8 days; p < 0.001). Out of 39 patients requiring ICU admission, 48.7% were surgically treated and 10.2% underwent endovascular intervention (p < 0.001). Mortality associated with surgery was 30.6% compared to only 6.6% with endovascular intervention (p < 0.001). Between 2007 and 2012, only one patient underwent endovascular intervention and 20 underwent surgery compared to 14 patients treated with endovascular approach and 16 with surgery between 2013 and 2018. Conclusion In this non-randomized, retrospective case series, patients with endovascular treatment fared clinically better and the intervention was found to be safe and feasible in the selected group of patients. We suggest a preference for this modality where possible. At our hospital, a trend favoring this approach is apparent during the last six years.

Abstract
OBJECTIVES Endovascular access is usually achieved through the common femoral artery due to its large size and accessibility. Access through the upper extremity can however be necessary due to anatomic reasons, obesity, or peripheral arterial disease. The two main methods of access are surgical cutdown and percutaneous puncture. In this single-centre retrospective cohort study we compared complication risks for both surgical cutdown and percutaneous puncture of an upper arm approach. MATERIALS AND METHODS Data was obtained from patients receiving endovascular access through the brachial or axillary artery between 2005 and 2018. A total of 109 patients were included. Patient demographics including age, sex, medical history, smoking status, and actual medication were registered, as well as postoperative complications including hematoma, thrombosis, dissection, infection, pseudoaneurysm, nerve injury, reoperation, and readmission. RESULTS Access was achieved through surgical cutdown in 53% (n=58) and through percutaneous puncture in 47% (n=51) of patients. Fifty-eight percent (n=63) received access via the brachial artery and 42% (n=46) via the axillary artery. Complication rate was 25.0% (3 of 12) for surgical cutdown via the brachial artery, 29.4% (15 of 51) for percutaneous puncture via the brachial artery, and 10.9% (5 of 46) for surgical cutdown via the axillary artery. Major complication rate was 8.3% (1 of 12) for surgical cutdown via the brachial artery, 13.7% (7 of 51) for percutaneous puncture via the brachial artery, and 4.3% (2 of 46) for surgical cutdown via the axillary artery. There was no association between baseline patient characteristics and complication rate. CONCLUSIONS In this non-randomized retrospective study, surgical cutdown via the axillary artery was the safest option with fewest complications, but selection of patients may have blurred the results. Surgical cutdown and percutaneous puncture seem equally safe in terms of complication rate in the brachial artery.

Abstract
OBJECTIVE To investigate the safety and efficacy of a balloon-expandable covered stent in the treatment of complex aortoiliac artery disease. BACKGROUND Peripheral intervention in complex aortoiliac disease still remains a challenge. METHODS We retrospectively analyzed symptomatic patients with aortoiliac disease who were treated with GORE® VIABAHN® VBX covered stent (W.L. Gore & Associates, Flagstaff, AZ). The primary study outcome was a 1-year primary patency without the necessity of any subsequent clinically-driven target revascularization (CD-TLR) based intervention. The proportion of technical success, defined in terms of the absence of residual stenosis, stent edge dissection, and procedure-related severe complications, was also reported. RESULTS VBX covered stent was used in 231 patients. Key patient characteristics include mean age of 73.4 ± 9 years, 77% male, 45% diabetes, and 18% suffering from end-stage renal dysfunction on dialysis. TASC II CD lesions were observed in 51% patients, which included 81% calcified lesions. Combined therapy with standard self-expandable stent was performed in 40% patients. The technical success rate was 92.6%. During median follow-up after 13.1 months, the primary patency rate was estimated to be 93.4% (95% confidence interval, 90.0%-96.8%) at 12 months, whereas the rate of freedom from TLR was 95.3% (92.5%-98.2%). As per the univariate analysis, the TASC II classification, number of diseased regions, and chronic total occlusion were significantly associated with risk of restenosis. CONCLUSIONS The results of the year-long AVOCADO study demonstrated that usage of the novel VBX covered stent has a patency-based advantage with reduced chances for subsequent revascularization procedures.

Abstract
Background: Revascularization surgery sometimes can achieve recanalization in patients with internal carotid artery occlusion (ICAO). High-resolution vessel wall magnetic resonance imaging (HRVWI) is a feasible technique to give detailed characteristics of the vessel wall, which may help to identify patients that carry higher success rates and more suitable for revascularization surgery. Objective: To examine the association between HRVWI characteristics of ICAO and the success rate of revascularization surgery in ICAO patients. Methods: We conducted a retrospective analysis of 31 ICAO recanalization patients enrolled from October 2017 to May 2019. The clinical data of patients and lesions were collected and analyzed. Results: A total of 31 ICAO patients were enrolled in this study. No significant differences were found between recanalization success and recanalization failure groups with regard to occlusion length, distal end of the occluded segment, and the treatment applied. The ipsilateral-to-contralateral diameter ratios (I/C ratios) of C1 or C2 and the diameter of C7 were positively related to recanalization success. A two-factor predictive model was constructed, and the I/C ratio of C2 < 0.86 and the diameter of C7 < 1.75mm were separately assigned 1 point. The ICAO patients who scored 0, 1, or 2 points had a risk of 5.6% (1/18), 55.6% (5/9), or 100% (4/4) to fail in the recanalization. Conclusions: The I/C ratios of C1 or C2 and the diameter of C7 are predictive factors of a revascularization surgery success in ICAO patients. A risk stratification model involving C2 and C7 was constructed for future clinical applications.
