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

Background: Bilateral limb occlusion after endovascular repair of abdominal aortic aneurysms (EVAR) is an uncommon entity. The relationship between graft kinking and unilateral limb occlusion is widely described in the literature. Our aim is to report a case of complete endograft thrombosis due to bilateral limb kinking secondary to aneurysm sac shrinkage, treated by endovascular means.

Self-Made Bovine Pericardial Tube Grafts for the Treatment of Abdominal Aortic Infections.

Background: Aortic infections are uncommon but life-threatening diseases. The material of choice for aortic reconstruction is still a matter of debate. The aim of this study is to examine the short- and mid-term outcomes in the treatment of abdominal aortic infections using self-made bovine pericardium tube grafts.

Prospective analysis on carotid endarterectomy: intermediate-deep ultrasound-guided cervical blockade versus general anesthesia.

Background: The best regional anesthesia plan with the best clinical results for Carotid endarterectomy (CEA) has not been defined yet.

Methods: Prospective multicentric observational study of two non-randomized matched cohorts including patients undergoing elective unilateral CEA (N.=100) between January-October 2021.

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.

Incidence, Characteristics, Laboratory Findings and Outcomes in Acro-Ischemia in COVID-19 Patients.

Aim: In addition to its respiratory impact of SARS-CoV2, skin lesions of probable vascular origin have been described. This study intends to quantify the incidence of acro-ischemic lesions in COVID-19 infected adult subjects in our population, describing clinical patterns and associated findings.

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.

Midterm Results of Endovascular Treatment for Complete Iliac Axis Occlusions Using Covered Stents.

Background: Endovascular treatment of complex aortoiliac disease is seeing a growing popularity despite the Trans-Atlantic Inter-Society Consensus (TASC) II recommendations for open surgery in this cases. However, the available evidence does not focus particularly on patients with complete unilateral iliac axis obstruction (CIAO) (TASC II D4 group). This study reports mid-term results of endovascular therapy with covered stents for CIAO.

Results of Transarterial Embolization for Treating Type 2 Endoleaks: A Single-Center Experience.

Background: Type 2 endoleaks (T2Es) are the main cause of reintervention after endovascular repair of abdominal aortic aneurysms (EVAR). The objective of this study is to quantify success rates of T2E treatment.

Methods: This study involves a retrospective analysis of a prospectively maintained database containing data on all consecutive patients treated for a T2E between 2003 and 2017 in a single center.

Effect of antiplatelet therapy on aneurysmal sac expansion associated with type II endoleaks after endovascular aneurysm repair.

Objective: Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAAs) has gained widespread use through a solid reputation of safety and effectiveness. However, some issues, such as endoleaks and sac growth over time, still arise as important concerns. Antiplatelet therapy, mandatory as secondary prevention of cardiovascular disease, may play a role in both phenomena by interfering with blood clotting properties and the inflammatory process associated with AAA.
