Update About the Management of Low-Density Lipoprotein Cholesterol and Hypertriglyceridemia in Lower Extremity Peripheral Artery Disease Patients: Consensus of the French Society of Vascular Medicine and the French Society for Vascular and Endovascular Surgery.

BACKGROUND: A French intersociety consensus on behalf the Société Française de Médecine Vasculaire and the Société de Chirurgie Vasculaire et Endovasculaire was proposed in 2021 for the management of patients with lower extremity peripheral artery disease (LEAD). Recent studies have been published and an update of this consensus about the management of low-density lipoprotein cholesterol (LDLc) and hypertriglyceridemia was required. METHODS: A steering committee of 12 vascular physicians and surgeons defined questions of interest about LDLc and hypertriglyceridemia management. A French expert panel voted the proposals. Consensus was considered to have been achieved if more than 80% of the responses corresponded to either "Agreement" or "Disagreement". RESULTS: Among the 56 experts who were asked to participate, 46 (82%) accepted. After the first round of the Delphi procedure, the 4 proposals reached consensus. The following suggestions and recommendations were approved: 1. For LEAD patients treated by the highest tolerated statin dose ± ezetimibe and who have an LDLc ≥0.70 g/L, we recommend adding a proprotein convertase subtilisin/kexin type 9 inhibitor. 2. For LEAD patients treated by statin and who have elevated triglyceride level between ≥150 mg/dL and ≤500 mg/dL, we suggest adding Icosapent Ethyl. 3. Before adding Icosapent Ethyl in LEAD patients treated with statin, we suggest looking for symptoms that may suggest atrial fibrillation. 4. For LEAD patients treated by Icosapent Ethyl and who have symptoms that suggest atrial fibrillation, we recommend performing an electrocardiogram. CONCLUSIONS: This update will help clinicians to improve LEAD patient management.

Robotic Surgery For in situ Renal Artery Aneurysm Repair: Technical Note and Literature Review About a Mini- Invasive Alternative.

CASE REPORT: Classical surgical options for renal artery aneurysm (RAA) are usually restricted to endovascular surgery or open repair, either using an in-situ or ex-situ approach. A 45-year-old woman presenting with a 20-mm complex RAA with hilum location, not suitable for endovascular repair renal was treated with a mini-invasive robotic approach. This approach allowed an in-situ reconstruction in a complete mini-invasive manner with the Da Vinci Xi robot (Intuitive Surgical, Sunnyvale, CA). The robotic system was used for both surgical exposure and aneurysmectomy with patch closure. Clamping time was 38 minutes (warm ischemia), total operative time was 210 minutes. LIITERATURE REVIEW: A comprehensive literature review was performed concerning the studies reporting a robotic approach for RAA. Main outcomes of interest were surgical technique, total operative time, clamping time, blood loss and postoperative renal function. Seven studies were identified, reporting a total of 20 RAAs. Most of the RAA were treated by aneurysmoraphy (n=9). Median total operative time varied between 228 and 300 min (range: 155 - 360 minutes), median clamping time varied between 26 and 44 minutes (range: 10 - 82 minutes). Median blood loss was comprised between100 and 150 mL (range: 25 - 650 mL). No alteration of renal function in the early post-operative period was reported. CONCLUSION: RAA in-situ repair with a robotic approach is feasible and safe and should be considered as an alternative to open surgical repair when endovascular technique cannot be an option.

Disparities Between International Guidelines (AHA/ESC/ESVS/ESVM/SVS) Concerning Lower Extremity Arterial Disease: Consensus of the French Society of Vascular Medicine (SFMV) and the French Society for Vascular and Endovascular Surgery (SCVE).

Several international guidelines concerning lower extremity arterial disease (LEAD) have been published recently, in particular, by the American Heart Association the European Society of Cardiology/European Society for Vascular Surgery, the European Society for Vascular Medicine and the Society for Vascular Surgery. These guidelines differ in some respects and certain issues are not addressed. The objective of this consensus driven by the French Societies of vascular Medicine and surgery was to analyze the disparities between the different guidelines, as well as certain issues not covered, and develop proposals with regard to these points. The following fields of LEAD have been explored: 1) classifications, 2) clinical evaluation, 3) diagnostic criteria, 4) quantification of arterial stenosis using duplex ultrasound, 5) detection of asymptomatic multisite lesions, 6) screening for LEAD in the context of cardiac disease, 7) medical treatment, 8) supervised exercise therapy, 9) revascularization and revascularization of the internal artery stenosis, 10) management of chronic limb ischemia, 11) longitudinal follow-up, and 12) diet.

Management of upper extremity aneurysms: a systematic review.

INTRODUCTION: The aim of this paper is to provide recommendations for diagnosis and management of arterial or venous aneurysms of the upper extremity. EVIDENCE ACQUISITION: A systematic review of the Medline and Cockrane databases was performed from 1988 to 2019 by a combined strategy of MeSh terms. EVIDENCE SYNTHESIS: One-hundred-forty-four publications were identified: 111 addressing arterial aneurysms and 33 addressing venous aneurysms. A total of 162 cases of arterial aneurysms, mostly brachial aneurysms (34.0% of cases) and 40 cases of venous aneurysms, mostly located in the forearm (60.0% of cases) were reported. For both types of aneurysms, most common presentation was the perception of a mass (56.3% for arterial one and 87.5% for venous one), but thromboembolic complication (46.7%), paresthesia (16.5%) or rupture (6.4%) could be observed in the setting of arterial aneurysms, while arm swelling (27.5%), neurological symptoms (12.5%), pulmonary embolism (10.0%) or rupture (2.5%) could occur in the setting of venous aneurysms. DUS was performed as first imaging modality for both settings, followed but CTA and MRA, especially in arterial aneurysms, to evaluate distal emboli and surrounding vasculature. Surgical treatment was mostly based on excision of the aneurysms with revascularization for arterial aneurysms (77.2%) and resection without reconstruction for the venous one (85.0%). Complications occurred in 10.5% of the cases of arterial aneurysms, none occurred after venous aneurysm resection. CONCLUSIONS: Prompt diagnosis and appropriate preoperative imaging are mandatory in order to offer the best treatment modality. Open resection with revascularization seems to be the treatment of choice for arterial aneurysms, although endovascular procedures became more popular. Venous aneurysms require excision without revascularization.

Heart valves from polyester fibers: a preliminary 6-month in vivo study.

Transcatheter aortic valve implantation (TAVI) has become a popular alternative technique to surgical valve replacement for critical patients. Biological valve tissue has been used in TAVI procedures for over a decade, with over 150,000 implantations to date. However, with only 6 years of follow up, little is known about the long-term durability of biological tissue. Moreover, the high cost of tissue harvesting and chemical treatment procedures favor the development of alternative synthetic valve leaflet materials. In that context, textile polyester [polyethylene terephthalate (PET)] could be considered as an interesting candidate to replace the biological valve leaflets in TAVI procedures. However, no result is available in the literature about the behavior of textile once in contact with biological tissue in the valve position. The interaction of synthetic textile material with living tissues should be comparable to biological tissue. The purpose of this preliminary work is to compare the in vivo performances of various woven textile PET valves over a 6-month period in order to identify favorable textile construction features. In vivo results indicate that fibrosis as well as calcium deposit can be limited with an appropriate material design.
