Psoas muscle analysis as a surrogate marker of sarcopenia and frailty: A multicenter analysis of predictive capacities over short- and long-term outcomes after abdominal aortic aneurysm repair.

Objectives: Several predictive models exist for estimating the postoperative risks of abdominal aortic aneurysm (AAA) repair, although no particular tool has seen widespread use. We present the results of a multicenter, historic cohort study comparing the predictive capacity of the psoas muscle area (PMA), radiodensity (PMD), and lean muscle area (LMA) as surrogate markers of sarcopenia, over short- and long-term outcomes after AAA repair, compared to the mFI-5 and American Society of Anesthesiologists (ASA) scales.

Methods: Retrospective review was conducted of all consecutive AAA elective repair cases (open or endovascular) in three tertiary-care centers from 2014 to 2019.

Aneurysm Sac Shrinkage After EVAR Can Lead to Complications: A Case Report of Complete Endograft Thrombosis Due to Kinking.

Prospective Observational Study after Eversion Carotid Endarterectomy with Ultrasound-Guided Deep-Intermediate Cervical Plexus Blockade.

(1) Introduction: The aim was to describe the anesthetic and surgical technique of eversion carotid endarterectomy performed under intermediate-deep cervical block with sedation, and to analyze the intraoperative and postoperative results. (2) Material and Methods: Thirty cases of unilateral eversion carotid endarterectomy (n = 30), performed between 2019-2020 in a tertiary center under intermediate-deep ultrasound-guided cervical plexus block and sedation, were prospectively observed and analyzed. Hemodynamic (blood pressure, heart rate) and neurological (cerebral oximetry) variables were measured in four intraoperative phases: at the beginning of the operation, prior to carotid clamping, after unclamping and at the end of the operation.

Midterm results of endovascular versus open surgical repair for infrarenal abdominal aortic aneurysms in low surgical risk patients.

Objective: The objective of this study was to analyze midterm outcomes of endovascular repair (EVAR) versus open repair (OR) for treatment of infrarenal abdominal aortic aneurysms (AAAs) in low surgical risk patients.

Methods: Elective patients with AAAs undergoing treatment from 2003 to 2017 in a single, tertiary-care institution were evaluated. All patients with a low preoperative risk of complications and perioperative mortality (Medicare Aneurysm Scoring System <3) were included, and rates of perioperative and long-term mortality, adverse events, and reintervention were evaluated for EVAR and OR.

Endovascular Aortic Repair in Nonagenarian Patients.

Background: The increasing proportion of elderly patients being treated for abdominal aortic aneurysm (AAA) in the endovascular era is controversial.

Objectives: This study compared 30-day outcomes of endovascular aortic repair (EVAR) in nonagenarians (NAs) with non-nonagenarians (NNAs).

Methods: This retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database included EVAR procedures performed from 2011 to 2017.

Immunological Aspects Involved in the Degeneration of Cryopreserved Arterial Allografts.

Cryopreserved arterial allografts have remained an option in patients requiring distal revascularization or associated with vascular infection, in the absence of a valid autogenous saphenous vein. The objective of this study is to describe the different clinical, anatomopathological, and immunological findings related to vascular transplant rejection. In a prospective trial, 35 patients who underwent cryopreserved allogeneic arterial bypass were studied, including demographics and conduit patency.

Methods: All adult confirmed cases of COVID-19 infection who presented with acro-ischemic lesions and received care in our institution were prospectively enrolled up to May 15th, 2020.

On the importance of tunica intima in the aging aorta: a three-layered in silico model for computing wall stresses in abdominal aortic aneurysms.

Layer-specific experimental data for human aortic tissue suggest that, in aged arteries and arteries with non-atherosclerotic intimal thickening, the innermost layer of the aorta increases significantly its stiffness and thickness, becoming load-bearing. However, there are very few computational studies of abdominal aortic aneurysms (AAAs) that take into account the mechanical contribution of the three layers that comprise the aneurysmal tissue. In this paper, a three-layered finite element model is proposed from the simplest uniaxial stress state to geometrically parametrized models of AAAs with different asymmetry values.

Endovascular Treatment of a Traumatic Axillary Artery Rupture Using the Dual Bull's-Eye Technique.

Background: Our purpose is to report a case of an axillary artery rupture treated by endovascular means using the dual bull's-eye technique. An 83-year-old woman with multiple comorbidities was diagnosed with axillary artery rupture after the reduction of a shoulder dislocation.

Methods: An endovascular repair attempt was made, but, despite the use of a double approach (antegrade and retrograde), reconnecting both ends of the severed artery was deemed not possible.
