SFA courses through adductor canal and turns into popliteal artery in the popliteal fossa GSV: originates at the ankle, tracts anterior to medial malleolus and then ascending the medial side of lower leg. Upon reaching the knee, it curves behind the medial condyles of the femur and tibia, continuing alongside the medial aspect of the thigh. Its journey culminates at the saphenofemoral junction Preoperative preparation: Identifying inflow and outflow vessels, both should be free of significant disease preop CTA or angiogram Picking a conduit Best patency=autogenous: reversed GSV most common, others are small saphenous vein, cephalic vein, etc Prosthetic: polytetrafluoroethylene (PTFE) Cryopreserved vein   Surgical steps: Harvesting GSV (if GSV adequate as conduit) Dissected along its length, branches ligated, removed and reversed Can also be left insitu, so only proximal and distal aspects are mobilized, and valves are removed using valvulotome Should be at least 3mm in diameter and no significant disease (scarring, thickening) Arterial exposure Common femoral artery: lies in the medial third segment between the ASIS and the pubic symphysis. Longitudinal or oblique incision directly over the femoral artery pulse if present. ligate venous and lymphatic tributaries in the soft tissue. Open fascia along the medial margin of the sartorius muscle, retracting the sartorius muscle laterally exposes the underlying femoral sheath. CFA is located within the femoral sheath. Profunda and superficial femoral artery: trace the anterior surface of the CFA to where it bifurcates. The origin of the profunda is typically lateral Popliteal artery: medial longitudinal incision 1 to 2 cm behind the tibia's posterior border. Carefully to avoid GSV, dissect down to fascia to enter the popliteal fossa. The medial head of the gastrocnemius is retracted posteriorly, giving us a clear view of the popliteal fossa. popliteal artery is surrounded by paired popliteal veins with smaller bridging veins Tunneling and anastomosis Can be done anatomically or subcutaneously Must be careful not to twist the conduit Can do proximal anastomosis to pressurize vein prior to tunneling to minimize chance of twisting Clamp the vessels and heparinize Arteriotomy on femoral artery and anastomosis, same with popliteal artery distally Closure and ensure patency Optional completion angiogram Postoperative care: Anticoagulation and/or antiplatelet therapy Monitor graft patency once discharged with duplex/ABI Follow us @audiblebleeding Learn more about us at https://www.audiblebleeding.com/about-1/ and provide us with your feedback with our listener survey.

In this episode Abena Appah-Sampong (@abenasamp) and Leana Dogbe (@leanadogbe) partner with Vaiva Dabravolskaite (vaivadabravolskaite@gmail.com) from ESVS to host an episode discussing social deprivation in vascular surgery. Dr. Tara Mastracci and Dr. Olamide Alabi join us to offer insights into how social deprivation drives disparities in outcomes and steps to how we can shift practice paradigms to better address our patient needs.   Dr. Tara Mastracci (@aorticsurgeon) is a vascular surgeon with over 15 years of experience treating and managing complex aortic pathologies. She is currently working at St. Bartholomew’s Hospital in London, UK, on the Cardiothoracic Team doing complex aortic surgery. On top of her clinical duties, Dr. Mastracci is dedicated to studying the social and non-clinical factors influencing vascular outcomes.    Dr. Olamide Alabi (@OAlabiMD) is an Associate Professor of Surgery in the Department of Surgery at Emory University School of Medicine. Her clinical effort focuses on the full scope of vascular disease for patients at Emory University Hospital and the Atlanta VA HealthCare System, however, her academic portfolio and funded research is focused primarily on the intersection of peripheral artery disease, quality, and health equity.    References: Social Deprivation and the Association With Survival Following Fenestrated Endovascular Aneurysm Repair/2021 https://www.annalsofvascularsurgery.com/article/S0890-5096(21)00872-4/fulltext Is social deprivation an independent predictor of outcomes following cardiac surgery?

Etiology of Carotid Artery Stenosis Risk factors: advanced age, tobacco use, hypertension, diabetes. Atherosclerosis as the primary cause. Development of Atherosclerotic Disease and Plaque Formation LDL accumulation in arterial walls initiating plaque formation. Inflammatory response, macrophage transformation, smooth muscle cell proliferation. Role of turbulent blood flow at carotid bifurcation in plaque development. Clinical Features of Carotid Artery Stenosis Asymptomatic nature in many patients. Symptomatic presentation: Transient ischemic attacks, amaurosis fugax, contralateral weakness/sensory deficit. Carotid bruit as a physical finding, limitations in diagnosis. Importance of Evaluating CAS Assessing stenosis severity and stroke risk. Revascularization benefits dependent on stenosis severity. Classification of Stenosis Levels Clinically significant stenosis: ≥ 50% narrowing. Moderate stenosis: 50%–69% narrowing. Severe stenosis: 70%–99% narrowing. Stroke Risk Associated with Carotid Stenosis Annual stroke rate: ~1% for 50-69% stenosis, 2-3% for 70-99% stenosis. Diagnosis and Screening No population-level screening recommendation. Screening for high-risk individuals as per SVS guidelines. Carotid Duplex Ultrasound as primary diagnostic tool. Additional tools: CT angiography, Magnetic Resonance Angiography. Handling of <50% stenosis cases. Imaging Modalities Ultrasound: Noninvasive, cost-effective, potential overestimation of stenosis. CTA: Fast, high resolution, contrast exposure risks. MRA: Contrast-free plaque analysis, possible overestimation of stenosis. Angiography: Gold standard, expensive, stroke risk. Assessing Degree of Stenosis via CDUS Parameters for 50-69% stenosis: Peak Systolic Velocity (PSV) 125-229 cm/sec, End Diastolic Velocity (EDV) 40-100 cm/sec, Internal/Common Carotid peak systolic velocity Ratio 2-4. Parameters for 70-99% stenosis: PSV ≥ 230 cm/sec, EDV > 100 cm/sec, Internal/Common Carotid peak systolic velocity Ratio > 4. Revascularization Criteria Symptomatic Patients: 50-69% or 70-99% stenosis, life expectancy at least three or two years, respectively. Asymptomatic Patients: <50% stenosis, no revascularization; 50-69% stenosis, follow-up and surveillance; >70% stenosis, considering life expectancy. Surgical Indications and Contraindications Indications: symptomatic patients, life expectancy considerations. Contraindications: Stenosis <50%, severe comorbidities, 100% occlusion. Medical Management for All CAS Patients Lifestyle changes, high-intensity statin therapy, antiplatelet therapy. Decision Factors for Surgical Approaches TCAR, stenting, endarterectomy: situational preferences. Carotid Endarterectomy: Surgical Procedure Incision along anterior border of sternocleidomastoid muscle. Electrocautery through platysma muscle and subcutaneous tissues. Protecting the great auricular nerve, dividing the external jugular vein. Retracting sternocleidomastoid muscle, exposing carotid sheath. Dissecting internal jugular vein, ligating facial vein. Avoiding injury to the vagus nerve, dissecting the common carotid artery. Identifying and mobilizing the hypoglossal nerve, addressing the external carotid artery. Extending dissection from common carotid artery to beyond the internal and external carotid bifurcation. Longitudinal arteriotomy, plaque removal using a Freer elevator. Ensuring a smooth transition between endarterectomized artery and normal distal extent. Patch angioplasty for arteriotomy closure, sequential clamp release for de-airing. Neuromonitoring and Plaque Removal Neuromonitoring methods: EEG, SSEPs, TCD, cerebral oximetry, awake patient monitoring. Shunting and Vessel Closure Shunting indications: neurological status changes, EEG alterations. Carotid stump pressure measurement. Postoperative Complications and Management Common complications: stroke, hyperperfusion syndrome, myocardial infarction, cervical hematoma, nerve injuries, infection. Managing hyperperfusion syndrome: blood pressure control, antiepileptic drugs. Cranial nerve injuries:  Hypoglossal Nerve (CN XII): Injury leads to tongue deviation towards the injured side. Glossopharyngeal Nerve (CN IX): Injury results in swallowing difficulties and aspiration risk. Vagus Nerve (CN X): Injury causes hoarseness due to laryngeal muscle involvement. Marginal Mandibular Branch of Facial Nerve: Injury leads to ipsilateral lip droop.   Follow us @audiblebleeding   Learn more about us at https://www.audiblebleeding.com/about-1/ and provide us with your feedback with our listener survey.

Welcome to the Transatlantic series, a co-production of Audible Bleeding (a publication of the SVS) and the ESVS podcast.
