BACKGROUND: Endovascular technological advances have revolutionized the field of neurovascular surgery and have become the mainstay of treatment for many cerebrovascular pathologies. Digital subtraction angiography (DSA) is the 'gold standard' for visualization of the vasculature and deployment of endovascular devices. Nonetheless, with recent technological advances in optics, angioscopy has emerged as a potentially important adjunct to DSA. Angioscopy can offer direct visualization of the intracranial vasculature, and direct observation and inspection of device deployment...

OBJECTIVE: Randomized controlled trials (RCTs) constitute level I evidence and are used as the backbone of guidelines and recommendations for treatment. Although RCTs are theoretically the studies of choice for the assessment of the effectiveness of health care interventions, these trials (and their interpretation) may sometimes result in erroneous conclusions, erroneous therapeutic decisions, and incorrect recommendations. We aimed to check the applicability of the results of RCTs to everyday practice...

After the invention of the balloon catheter by Fogarty in 1963, surgical thromboembolectomy was considered the gold standard treatment for many years in patients with acute lower limb ischemia (ALLI). ALLI is a dramatic event, carrying a high risk of amputation and perioperative morbidity and mortality. The evolution of endovascular technologies has resulted in a variety of therapeutic options to establish arterial patency. In the 1970s, Dotter first introduced the idea of clot lysis in the treatment of ALLI, which was modified to catheter-directed thrombolysis, and now clot aspiration techniques...

In case of an acute leg swelling a deep leg vein thrombosis needs to be excluded. In order to do this, compression sonography and the D-dimer-test are applied in the framework of an established diagnostic algorithm. The ensuing therapy consists in anticoagulation and compression.In case of a chronic leg swelling anamnesis and a clinical check-up often lead to a differential diagnosis. Chronic venous insufficiency is a generic term for a disturbed venous backflow. It is caused by an obstruction or an antegrade or retrograde flow insufficiency...

Petrous internal carotid artery (ICA) aneurysms are rare, complicated lesions to treat. The management paradigms include observation, endovascular exclusion, or surgical trapping with or without revascularization. The case described in this video involved a 67-yr-old woman with a known history of chronic lymphocytic leukemia, who presented after a mechanical ground-level fall. Clinically, she had a nasal deformity and resolving epistaxis consistent with mild facial trauma. Computed tomography (CT) revealed a comminuted nasal bone fracture and an incidental 3-cm right petrous ICA aneurysm...

OBJECTIVE: Descending thoracic endovascular aneurysm repair (D-TEVAR) is often performed by vascular surgeons. At many institutions, cardiothoracic surgery support is required for an elective TEVAR to take place. Oftentimes, this means a dedicated cardiopulmonary bypass team must be available. This study aims to investigate that TEVAR is a safe procedure that does not require such a resource-intensive "back-up plan." METHODS: This is a retrospective analysis of data collected from March 2014 to January 2018 of 18 patients who underwent TEVAR at a tertiary care facility with a level I trauma center...

REVIEW
Maarten P van Wiechen, Jurgen M Ligthart, Nicolas M Van Mieghem
Endovascular aneurysm repair, transcatheter aortic valve implantation and percutaneous mechanical circulatory support systems have become valuable alternatives to conventional surgery and even preferred strategies for a wide array of clinical entities. Their adoption in everyday practice is growing. These procedures require large-bore access into the femoral artery. Their use is thus associated with clinically significant vascular bleeding complications. Meticulous access site management is crucial for safe implementation of large-bore technologies and includes accurate puncture technique and reliable percutaneous closure devices...

BACKGROUND: Bypass surgery (BS) remains the gold standard revascularization strategy in patients with chronic limb-threatening ischemia (CLTI) owing to infrainguinal disease. The Bypass versus Angioplasty for Severe Ischaemia of the Leg (BASIL)-1 trial showed that, in patients with CLTI who survived for 2 years or more, BS resulted in better clinical outcomes. Despite this finding, there has been an increasing trend toward an endovascular-first approach to infrainguinal CLTI. Our aim was to investigate whether changes in practice have impacted the clinical outcomes of BS in our unit 10 years after BASIL-1...

OBJECTIVE: Recent vascular societal guidelines have recommended an abdominal aortic aneurysm (AAA) size threshold for elective intervention; however, limited data have documented how well these AAA diameter benchmarks are being met. The objective of this study was to analyze variation in management of AAAs based on diameter and to determine the physician's rationale for intervention on small AAAs in relation to recommended treatment guidelines. METHODS: A retrospective review of a statewide vascular surgery registry of all elective endovascular or open surgical AAA repairs from January 2012 to January 2016 was performed...

OBJECTIVE: Infrarenal aortic neck angulation is one of the most powerful predictors of endovascular aneurysm repair failure. Whereas the "gold standard" to measure this angle is three-dimensional (3D) reconstruction and centerline measurement, many surgeons rely on estimations of angulation based on two-dimensional (2D) views of computed tomography imaging. Unfortunately, these views do not accurately represent the true angle, particularly if aortic angulation is oblique to the standard views...

Coil migration and extrusion outside the cranial compartment after embolization of cerebral aneurysms represents a very rare complication of the endovascular procedures and few cases are reported in the literature. Instability of the vascular malformation wall and the resolution of the intramural hematoma, especially in pseudoaneurysm, might generate extravascular migration of the coils in the first months after embolization. However, to the best of our knowledge, an extrusion of coil 10 years after embolization has never been reported...
