Abstract
Abstract
Objective
In case of complex aortic aneurysmal disease, fenestrated or branched EVAR (b/f-EVAR) is considered as a valid and safe alternative to open surgery. However, one the main limitation is the time required for manufacture, limiting its use in emergent situations. The new off-the-shelf 4 inner branches E-nside (Jotec, Hechingen, Germany) has been developed to offer a solution in such circumstances. The aim of this study was to report our preliminary monocentric experience with this new device.
Methods
Retrospective analysis of prospective data retrieved from 1 center between November 2020 and January 2022 was done. Endpoints were technical success, postoperative morbidity, rate of endoleak and any aneurysm-related re-interventions during follow-up.
Results
In this study, 15 patients (mean age 73 years, range 59–90) were identified. There was a majority of male (9/15) and all of them but 3 were asymptomatic. The mean aneurysmal diameter was 60 mm (range 50–100). There were 3 cases of juxtarenal aortic aneurysms (20%), 1 Crawford type I (7%), 4 type II (27%), 4 type III (27%) and 3 type IV (20%) aneurysms. In 7 cases, a 2-steps procedure was done with a TEVAR first followed by Enside implantation. There was a technical success in 93% with 1 open conversion for a mesenterical bypass. There was no death in the post-operative period. During the post-operative period, 33% of patients (5/15) presented complications with 3 complications related to the femoral or iliac access and 2 cases of spinal cord ischemia (13%). One case occurred in an emergent setting of a type III aneurysm rupture. The other case was the open conversion and the patient also developed a colic ischemia and finally died 4 months alter. The mean length of stay was 9 days. During the follow-up, 2 reinterventions were necessary, 1 for a type Ic endoleak with distal prolongation of the stent and 1 renal stent occlusion treated by relining. The overall target vessel patency was 98%.
Conclusion
The use of the off-the-shelf 4 inner branches E-nside appears to be safe with good technical success for the treatment of complex aortic aneurysmal disease. It is associated with an acceptable rate of complications and allows for treatment of a wide variety of diseases in an emergent setting. Further patients and longer follow-up are required to better evaluate the exact role of this new device.

Abstract
Abstract
Objective
Vascular patients suffer some of the highest complications rates. Surprisingly, there is no uniformly accepted medical therapy to reduce complications in these patients. Time restricted feeding (TRF) is an approach that emphasizes energy intake limited to certain windows of time within the 24-hour cycle, without restrictions on any calories or macronutrients. In healthy young human, TRF improves cardio-metabolic fitness. However, there is a lack of research on TRF in patient undergoing surgery, and suffering from cardiovascular diseases. This study aims to investigate the feasibility and efficacy of a pre-operative 2-week, 10-hour TRF in patient undergoing vascular surgery.
Methods
The OptiSurg Study is a randomized open-label clinical trial, that plan to enroll 40 patients, undergoing elective femoral endarterectomy. Only Fontaine stage II peripheral artery disease, and a BMI ≥ 20 kg/m2 are included. Patients are randomized with a 1:1 ratio to either the control or intervention group. The control group receives diet nutritional counselling (standard of care, SOC). The intervention group receives the same SOC and a self-selected 10-hour TRE window. After the surgery, patients will be on SOC only, and followed every 3 months up to 1 year. Primary endpoint is a composite of death, myocardial infarction, stroke, and surgical re-intervention at 1 month post-operative. Blood glucose, body weight, body composition, biomarkers (neuroendocrine, inflammatory and metabolic), sleep and quality of life will also be examined. Temporal calorie intake is monitored with the smartphone application myCircadianClock preoperatively. VascuQoL-6 is used to monitor quality of life.
Results
9 participants were enrolled since the start of the recruitment in February 2021, 4 were randomized in the 8 hours TRF intervention, and 5 to SOC. They all completed the study: 7 men and 2 women, age 73, 53–87 (median, min-max) years. Using the myCircadianClock app, adherence to the TRF was >90% (Figure 1).
Conclusion
Our preliminary experience seems to demonstrate that a 2-week TRF regimen before vascular surgery is feasible. The complete results will be disseminated through future peer-reviewed manuscripts, reports and presentations.

Abstract
Abstract
Objective
Endovascular repair (EVAR) has become the standard of care for treatment of abdominal aortic aneurysms. However, a significant number of EVAR remains outside the IFU, especially in cases of severe proximal angulation (>60 degrees), resulting in failure. The new device GORE EXCLUDER Conformable AAA Endoprosthesis (W. L. Gore & Associates, Flagstaff, Ariz) has been designed to accommodate neck angulation, due to conformability and angulation control. The aim of this multicenter study is to report the initial results of this device.
Methods
From March 2019 to January 2021, the data of all consecutive patients with AAA treated with the Gore Excluder Conformable endograft at 4 vascular centers were reviewed. Patients were followed using a standardized protocol, with CT-scan at 1, 6 and 12 months, and then yearly. The primary endpoint was technical success and secondary outcomes were postoperative morbidity, rate of endoleak (EL) and any aneurysm-related re-interventions during follow-up.
Results
Among the 32 patients included, most were men with a mean age of 77 years old (range 60-92). Half of patients were smokers and 72% had hypertension. The mean diameter of AAA was 62 mm (47-90). The mean length of aortic neck was 26 mm (10-69), the mean diameter 23 mm (16-31) and the median neck angulation was 81 degrees (range 40-110). The mean procedural duration was 102 min (54-153) with a mean time of scopy of 24 min (8-47) and a total volume of contrast of 101 ml (40-165). Thirteen iliac branch device have been used in 7 patients. The technical success was 97% with 1 type Ia EL (3%). In the post-operative period, 4 medical and 3 surgical complications were observed. Two reinterventions were needed with an iliac stenting for a stenosis and a correction of a femoral false aneurysm. During the mean follow-up of 7 months, 2 type Ia ELs were observed. One spontaneously resolved and the other one was followed. One distal limb extension was succesfully implanted at 3 months for a type Ib EL for a total rate of reintervention of 9%. No migration was observed. No death occured.
Conclusion
The use of the Gore Excluder Conformable endograft seems to be safe and effective in difficult anatomies and especially high angulation. It allows for precise deployment without the need for additional contrast or operation time. Longer follow-up and more patients are required to confirm these excellent initials results.

Abstract
Abstract
Objective
This pilot study assessed the hypothesis that patient-specific computational fluid dynamic (CFD) modelling can detect aortic branch hemodynamic changes following branched endovascular aneurysm repair (bEVAR).
Methods
Patients who underwent bEVAR with the Jotec E-xtra Design for thoracoabdominal aortic aneurysms were retrospectively selected. Using open-source SimVascular software, pre- and post-operative aortic finite element volume meshes were constructed from CT imaging. Pulsatile in-flow conditions were derived and adjusted for patient-specific clinical variables. Outlet boundary conditions consisted of Windkessel models approximated from physiologic flow splits. Rigid wall flow simulations were then performed on pre- and post-operative models with equivalent boundary conditions. Computations were performed with an incompressible Navier-Stokes flow solver on a 72-core cluster.
Results
Pre- and post-operative flow simulations were performed on 10 patients undergoing bEVAR with a total of 40 target vessels (10 celiac, 20 superior mesenteric, 20 renal stents). Compared to pre-operative values, bEVAR was associated with a decrease in peak renal artery pressure (116.8 ± 11.5 vs 112.8 ± 11.6 mmHg, p<.001) and flow rate (13.7 ± 2.3 vs 12.9 ± 2.4 ml/s, p<.001). No post-operative differences were observed in pressure or flow rates in the celiac or mesenteric arteries (p=.10-.55). Representative perfusion waveforms from a single patient are shown in Figure 1. bEVAR resulted in a significant increase in aortic (1.4 ± 0.5 vs 4.3 ± 2.9 dynes/cm2, p=.009) and renal artery (24.3 ± 7.1 vs 35.4 ± 12.4 dynes/cm2, p=.23) wall shear stress; however, these values remained within the physiologic range. In certain graft configurations, 3D visualization of blood flow streamlines revealed areas of turbulent flow at the origin of external branches which were associated with decreased target artery perfusion (Figure 2).
Conclusion
Changes in para-visceral aortic geometry after bEVAR is associated with a decrease in computationally estimated renal perfusion, without significant changes to celiac or mesenteric hemodynamics. Further CFD simulation-based studies are needed to assess whether changes in branch configuration or hemodynamics after bEVAR can predict loss of branch patency.

Abstract
Abstract
Objective
Lifelong low-protein, high-carbohydrate diets extend lifespan in rodent. Consistently in human, the administration of oral carbohydrate drinks the day before surgery might improve clinical outcome. However, the fundamental questions of what represents a macronutritionally balanced diet, and how this impact surgical stress remain unanswered.
Methods
Here, we induced dietary protein dilution by giving mice ad libitum access to 50% sucrose water, without any food restriction. Mice were randomized into four regimens: regular diet (17,6 % protein, Ctrl), and a low protein diet (5.6% protein, LP), with or without high sucrose water (50% sucrose) for 7 days. At the end of the preconditioning, calorimetric data, fasting blood glucose, IGF1, glucose tolerance, and finally resistance to renal failure following a bilateral renal ischemia-reperfusion was evaluated.
Results
We demonstrate that access to carbohydrate drinks promotes dietary protein restriction despite a total caloric intake that was twice higher. This short-term self-restriction in daily protein, independent of caloric intake, improved insulin sensitivity, reduced serum triglyceride, and enhanced mitochondrial respiration as well as energy expenditure. Importantly, a 7-day pre-conditioning protein dilution regimen promotes recovery following kidney ischemia and reperfusion (IRI), a model of surgical stress. This protection from kidney IRI inversely correlated with pre-operative protein intake, but not carbohydrate or fat. The benefit of a low protein, high-carbohydrate regimen was independent of the protein sensing pathway eIF2α/ATF4, NRF2 and hydrogen sulfide, but instead required Insulin-like growth factor 1 (IGF1) downregulation.
Conclusion
These results support further clinical studies of a low protein diet combined with carbohydrate drinks prior to surgery.

Abstract
BACKGROUND The treatment of choice in end-stage renal disease is transplantation. Hemodynamic disturbances can evoke graft loss, while early ultrasound identification of vascular problems improves outcome. The aim of this study was to identify differences in postoperative complications with and without systematic intraoperative Doppler ultrasound use. METHODS The primary outcome was the postoperative rate of complications and the secondary aim was to find a predictive resistance index cut-off value, which would show where surgical reintervention was necessary. Over a 10-year period, 108 renal transplants were performed from living donors at our institution. In group 1 (n = 67), intraoperative duplex ultrasound and intraparenchymatous resistance index measurements assessed patients, while in group 2 (n = 41), no ultrasound was performed. RESULTS There were no intergroup differences in the overall postoperative complication rate or in benefit to graft or patient survival with Doppler use. However, significantly more vascular complications (10% vs 0%, P = .02) and more acute rejections (37% vs 10%) occurred in group 2 than in group 1. Therefore, an intraoperative cut-off value of the resistance index 0.5 was proposed to justify immediate surgical revision. CONCLUSIONS This is the first report demonstrating benefits of systematic intraoperative Doppler ultrasound on postoperative complications in renal transplantation from living donors. Our results support surgical revision with a resistance index <0.5.

Abstract
We report the case of a 58-year-old man who presented with thoraco-abdominal pain and right lower limb ischemia due to type B aortic dissection. Moreover, the patient was discovered to have several concomitant aortic arch anomalies (bovine arch, arteria lusoria, and left vertebral artery arising from the aortic arch). Taking into account this complex anatomy, emergent femoral exploration with fenestration and thrombectomy was performed. The blood flow to the right lower limb was restored. A few days later the aortic dissection spread proximally, and the aortic arch dilatation enlarged. Before total arch replacement could be performed, the aorta ruptured and the patient unfortunately died.

Abstract
Aneurysms of the deep femoral artery, accounting for 5% of all femoral aneurysms, are uncommon. There is a serious risk of rupture. We report the case of an 83-year-old patient with a painless pulsatile mass in the right groin due to an aneurysm of the deep femoral artery. History taking revealed no cardiovascular risk factors and no other aneurysms at other localizations. The etiology remained unclear because no recent history of local trauma or puncture was found. ACT angiography was performed, revealing a true isolated aneurysm of the deep femoral artery with a diameter of 90mm, beginning 1cm after its origin. There were no signs of rupture or distal emboli. Due to unsuitable anatomy for an endovascular approach, the patient underwent open surgery, with exclusion of the aneurysm and interposition of an 8-mm Dacron graft to preserve deep femoral artery flow. Due to their localization, the diagnosis and the management of aneurysms of the deep femoral artery can be difficult. Options are surgical exclusion or an endovascular approach in the absence of symptoms or as a bridging therapy. If possible, blood flow to the distal deep femoral artery should be maintained, the decision depending also on the patency of the superficial femoral artery. In case of large size, aneurysms of the deep femoral artery should be treated without any delay.

Abstract
Critical limb ischemia is a major public health problem in our western countries due to the epidemia of (diabesity). The outcome of patients suffering from critical limb ischemia reains poor with an amputation free survival rate at one year of about 50%. The treatment should be multidiciplinary and done in emergency in specialized centers to ensure the limb salvage: this management should be centered aroud 3 axis: the screening of the cardiovascular risk factors, the best medical treatment and the invasive approaches. Due to multiple endovascular technical innovations, more frail patients with com plex diseases can be treated with good results. Therefore, the endovascular treatment is essential in the management of such patients by vascular surgeons.

Abstract
OBJECTIVES Long occlusions in calcified crural arteries are a major cause of endovascular technical failure in patients with critical limb ischaemia. Therefore, distal bypasses are mainly performed in patients with heavily calcified arteries and with consequently delicate clamping. A new reverse thermosensitive polymer (RTP) is an alternative option to occlude target vessels. The aim of the study is to report our technical experience with RTP and to assess its safety and efficiency to temporarily occlude small calcified arteries during anastomosis time. METHODS Between July 2010 and December 2011, we used RTP to occlude crural arteries in 20 consecutive patients with 20 venous distal bypasses. We recorded several operative parameters, such as volume of injected RTP, duration of occlusion and anastomotic time. Quality of occlusion was subjectively evaluated. Routine on-table angiography was performed to search for plug emboli. Primary patency, limb salvage and survival rates were reported at 6 months. RESULTS In all patients, crural artery occlusion was achieved with the RTP without the use of an adjunct occlusion device. Mean volume of RTP used was 0.3 ml proximally and 0.25 ml distally. Mean duration of occlusion was 14.4 ± 4.5 min, while completion of the distal anastomosis lasted 13.4 ± 4.3 min. Quality of occlusion was judged as excellent in eight cases and good in 12 cases. Residual plugs were observed in two patients and removed with an embolectomy catheter, before we amended the technique for dissolution of RTP. At 6 months, primary patency rate was 75% but limb salvage rate was 87.5%. The 30-day mortality rate was 10%. CONCLUSIONS This study shows that RTP is safe when properly dissolved and effective to occlude small calcified arteries for completion of distal anastomosis.

Abstract
Open surgery is still the main treatment of complex abdominal aortic aneurysm. Nevertheless, this approach is associated with major complications and high mortality rate. Therefore the fenestrated endograft has been used to treat the juxtarenal aneurysms. Unfortunately, no randomised controlled study is available to assess the efficacy of such devices. Moreover, the costs are still prohibitive to generalise this approach. Alternative treatments such as chimney or sandwich technique are being evaluated in order to avoid theses disadvantages. The aim of this paper is to present the endovascular approach to treat juxtarenal aneurysm and to emphasize that this option should be used only by highly specialized vascular centres.

Abstract
OBJECTIVES The study aims to assess the feasibility and midterm outcome of trans-peritoneal laparoscopy for coeliac artery compression syndrome (CACS). DESIGN Retrospective chart review involving four European vascular surgery departments and two surgical teams. MATERIALS AND METHODS charts for patients who underwent laparoscopy for symptomatic CACS between December 2003 and November 2009 were reviewed. Preoperative computed tomography (CT) angiography and postoperative duplex scan and/or CT angiography were performed. RESULTS Eleven consecutive patients (nine women) with a median age of 52 years (interquartile range: 42.5-59 years) underwent trans-peritoneal laparoscopy for CACS. All patients had a history of postprandial abdominal pain; weight loss exceeded 10% of the body mass in eight cases. Preoperative CT angiography revealed coeliac trunk stenosis >70% in all cases. One patient had additional aortitis and inferior mesenteric artery occlusion, while another patient presented with an occluded superior mesenteric artery. Two conversions occurred (one difficult dissection and one aorto-hepatic bypass needed for incomplete release of CACS). The median blood loss was 195 ml (range: 50-900 ml) and median operative time was 80 min (interquartile range: 65-162.5 years). Symptoms improved immediately in 10/11 patients (no residual stenosis) while one remained unchanged despite a residual stenosis treated by a percutaneous angioplasty. Symptoms reappeared in one patient due to coeliac axis occlusion. The mean follow-up period was 35 ± 23 months (range: 12-78 months). CONCLUSION Our study demonstrates that trans-peritoneal laparoscopy for treating median arcuate ligament syndrome is safe and feasible. Additional patients and a longer follow-up are needed for long-term assessment of this laparoscopic technique.
