Feasibility and Safety of Using Carbon Dioxide Exclusively in Regular Endovascular Aortic Aneurysm Repair: Results of a Multicentre, Prospective, Zero Iodine Contrast Endovascular Aneurysm Repair Study.

Objective: Carbon dioxide (CO) angiography has emerged as a viable alternative to regular iodinated contrast medium (ICM) for guiding endovascular aneurysm repair (EVAR) procedures. This study aimed to evaluate the feasibility and safety of a standardised EVAR procedure using only CO angiography.

Methods: A prospective, multicentre, national study enrolled consecutive patients between January 2023 and January 2024 with asymptomatic abdominal aortic aneurysms measuring ≥ 55 mm and for whom a standard endovascular graft (instructions for use) was anatomically feasible.

A systematic review and meta-analysis on the outcomes of carotid endarterectomy after intravenous thrombolysis for acute ischemic stroke.

Background: Intravenous thrombolysis (IVT) is the mainstay of treatment for patients presenting with acute ischemic stroke, whereas carotid endarterectomy (CEA) is indicated in patients with symptomatic carotid stenosis. However, the impact of prior IVT on the outcomes of CEA (IVT-CEA) is not clear. The aim of this study was to determine whether IVT may create additional stroke and death risk for CEA, compared with CEA performed in the absence of a history of recent IVT, and to determine the optimal timing for CEA after IVT.

Guidelines on the diagnosis, treatment and management of visceral and renal arteries aneurysms: a joint assessment by the Italian Societies of Vascular and Endovascular Surgery (SICVE) and Medical and Interventional Radiology (SIRM).

The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them.

Effect of plaque morphological characteristics on the outcomes of carotid artery stenting.

Carotid artery stenting (CAS) represents today an accepted option for the treatment of severe carotid artery stenosis. The evolution of materials, techniques, perioperative medical management and patients' selection, has allowed to progressively reduce CAS complications. However, the main drawback of CAS is still represented by the risk of cerebral embolization, that may occur during several steps of the procedure and also in the early postoperative period.

Physician-Modified Single-Fenestrated EndoSuture Aneurysm Repair (FESAR) for Urgent Juxtarenal AAA Repair.

Purpose: To describe the endovascular treatment of a symptomatic juxtarenal abdominal aortic aneurysm (JAAA) using a combination of endoanchors (Heli-FX EndoAnchor, Medtronic, Minneapolis, Minnesota) and a physician-modified single-fenestrated endograft.

Technique: An 85 year-old patient unfit for open aortic repair presented for a symptomatic JAAA, characterized by an infrarenal neck with 0.6 cm in length and 23 mm in diameter.

Clinical Impact and Determinants of Fenestration to Target Vessel Misalignment in Fenestrated Endovascular Aortic Repair.

Objective: This single centre, retrospective study (2014 - 2022) on juxta-, pararenal, or thoraco-abdominal aortic aneurysms treated by fenestrated endovascular aortic repair (FEVAR) was conducted to investigate the clinical impact and determinants of fenestration to target vessel misalignment in FEVAR.

Methods: Pre-operative supracoeliac, pararenal, and infrarenal aortic angles were measured on three dimensional computed tomography angiography (CTA) reconstructions. Two components of misalignment were measured on the first post-operative CTA: horizontal misalignment (angle between the fenestration and the target vessel ostium on perpendicular CTA cuts) and vertical misalignment (vertical distance between the fenestration and the target vessel at its origin).

Fate of primary determinate and indeterminate target vessel endoleaks after fenestrated-branched endovascular aortic repair.

Objective: The aim of this study was to investigate the outcomes of primary determinate and indeterminate target vessel endoleaks (TVELs) after fenestrated-branched endovascular aortic repair (F-BEVAR).

Methods: We conducted a single-center retrospective study (2014-2023) on F-BEVAR for thoracoabdominal (TAAAs) or pararenal aortic aneurysms (PRAAs). TVELs were classified as "primary" if present at the first postoperative computed tomography angiogram.

Impact of Carotid Stent Design on Embolic Filter Debris Load During Carotid Artery Stenting.

Background: The carotid stent design may influence the risk of embolization during carotid artery stenting. The aim of the study was to assess this risk by comparing the quantity of embolized material captured by filters during carotid artery stenting, using different stent designs.

Methods: We conducted a single-center retrospective study of patients undergoing carotid artery stenting for asymptomatic carotid stenosis >70% (2010-2022) in a tertiary academic hospital (Padua University Hospital, Italy).

The "safe-line" technique as theoretical additional attempt to mitigate spinal cord ischemia after urgent complete endovascular exclusion of a thoracoabdominal aortic aneurysm.

We describe the feasibility of a technique for temporary aneurysm sac reperfusion after endovascular single-stage thoracoabdominal aortic aneurysm exclusion, to be used in the case of postoperative spinal cord ischemia. Two cases were treated for impending rupture of a thoracoabdominal aortic aneurysm. Before completion of sac exclusion, a supplementary buddy wire (V-18 control guidewire; Boston Scientific) was advanced in parallel fashion from the left percutaneous femoral access into the aneurysmal sac on the posterior aspect of the endograft.

The role of multimodal imaging in emergency vascular conditions: The journey from diagnosis to hybrid operating rooms.

Multimodal imaging is the incorporation of two or more imaging modalities during the same examination, and it has both diagnostic and treatment applications. The use of image fusion for intraoperative guidance in endovascular interventions is being extended increasingly to the field of vascular surgery, especially in the context of hybrid operating rooms. The aim of this work was to perform a review and narrative synthesis of the available literature in order to report on current applications of multimodal imaging in diagnosis and treatment of emergent vascular conditions.

The Value of Troponin Measurement in Carotid Revascularization: A Scoping Review.

Purpose: Patients undergoing carotid endarterectomy (CEA) or carotid artery stenting (CAS) are at substantially increased risk of short-term and long-term cardiac complications. Still, the role of perioperative troponin in predicting cardiac events remains unclear. The objective was to systematically summarize the existing evidence on the topic and provide directions for further research.

Open Versus Endovascular Repair With Covered Stents for Complex Aortoiliac Occlusive Disease: Cost Analysis Results.

Background: The aim of this work is to value cost-effectiveness of complex aortoiliac occlusive disease (AIOD) revascularization, by comparing in-hospital clinical outcomes and detailed costs of hospitalization of open and endovascular techniques.

Methods: This observational single-center retrospective cohort study included all patients who underwent AIOD revascularization from May 2008 to February 2018 and met inclusion and exclusion criteria. Patients were divided into 2 groups: open surgical repair and endovascular repair.

Technical tips and clinical experience with the Nexus Endospan arch branch stent-graft.

Aortic arch pathologies are commonly treated by open surgery which is still the gold standard. Patients that are unfit for surgery can be effectively treated mini-invasively with novel endovascular endograft specifically designed for the arch. Endovascular technology has remarkably improved in recent years and is a valid alternative option for the treatment of aortic arch.

Applications of Three-Dimensional Printing in the Management of Complex Aortic Diseases.

The use of three-dimensional (3D) printing is gaining considerable success in many medical fields, including surgery; however, the spread of this innovation in cardiac and vascular surgery is still limited. This article reports our pilot experience with this technology, applied as an additional tool for 20 patients treated for complex vascular or cardiac surgical diseases. We have analyzed the feasibility of a "3D printing and aortic diseases project," which helps to obtain a more complete approach to these conditions.
