INTRODUCTION: The LVIS Blue is an FDA-approved stent with 28% metallic coverage that is indicated for use in conjunction with coil embolization for the treatment of intracranial aneurysms. Given a porosity similar to approved flow diverters and higher than currently available intracranial stents, we sought to evaluate the effectiveness of this device for the treatment of intracranial aneurysms. METHODS: We performed an observational single-center study to evaluate initial occlusion and occlusion at 6-month follow-up for patients treated with the LVIS Blue in conjunction with coil embolization at our institution using the modified Raymond-Roy classification (mRRC), where mRRC 1 indicates complete embolization, mRRC 2 persistent opacification of the aneurysm neck, mRRC 3a filling of the aneurysm dome within coil interstices, and mRRC 3b filling of the aneurysm dome...

Kawasaki disease (KD) is the leading cause of acquired heart disease due to its complicated coronary artery lesions. Up to now, few studies were focused on the status of persistent coronary artery aneurysms (CAA) in KD patients. The present study was designed to identify the coronary artery outcomes and seek the risk factors associated with the regression of CAA in KD patients. One hundred and twenty KD patients with CAA hospitalized in Children's Hospital of Soochow University from Jan 2008 to Dec 2013 were prospectively studied by a 3-year follow-up...

Performing transcatheter aortic valve implantation in the presence of aneurysmatic aortopathy is widely contraindicated; however, it needs to be taken into account as bailout strategy in selected patients. Deliberate preoperative assessing measurements become the crucial key element in this context. After meticulous valve selection, retrograde access is obtained via the right subclavian artery additionally serving as backup arterial cannulation site in case of conversion. TAVI is then performed via the transapical route...

OBJECTIVE Intracranial aneurysms are vascular abnormalities associated with neurological morbidity and mortality due to risk of rupture. In addition, many aneurysm treatments have associated risk profiles that can preclude the prophylactic treatment of asymptomatic lesions. Gamma Knife radiosurgery (GKRS) is a standard treatment for trigeminal neuralgia, tumors, and arteriovenous malformations. Aneurysms associated with arteriovenous malformations have been noted to resolve after treatment of the malformation...

Vascular procedures in general, and specifically abdominal aortic aneurysm (AAA) repair, are associated with worse outcomes in female patients. However, how female gender influences outcomes in the setting of aneurysm-rupture remains unclear and may be even more pronounced when compared to elective operations. In this report, the authors aim to review the literature regarding ruptured AAA repair in women. Using the traditional threshold for AAA of 30mm of maximum diameter, the prevalence in women is lesser than in men...

INTRODUCTION: There is an increasing number of elderly in society and some of them may have an abdominal aortic aneurysm (AAA). The prevalence of AAA in octo-and non-agenarians indicates that this number could be substantial. The question is; is there an age limit for repair? This complex question incorporates ethical, political, economic and medical aspects. To answer part of this question a review of the outcome of elective and emergent AAA repair in those over 80 was done. EVIDENCE ACQUSITION: A litterature research was done in the Pubmed and Embase databases between 2007 and 2017 for either emergent and/or elective repair of AAA in individuals older than 80 years of age...

The advancement of endovascular therapy has led to minimally invasive solutions to increasingly complex aortic pathology, including thoracoabdominal aneurysms and those involving the visceral segment. Upper extremity access is beneficial in a variety of these complex interventions, and may be absolutely required for certain procedures such as placement of parallel chimney grafts. Traditionally, the brachial artery has been the primary access site on the arm, using either a percutaneous or open approach. Brachial access is safe and effective, and remains suitable for the majority of clinical situations...

BACKGROUND: Posterior communicating artery (PCoA) aneurysms are among the most common aneurysms. Because blockage of the PCoA and perforators can cause adverse outcomes, occlusion of these arteries by surgical clipping should be avoided. The impact of factors on PCoA perforator infarction when using a distal transsylvian approach for PCoA aneurysms was examined. METHODS: A total of 183 patients underwent PCoA aneurysm clipping, excluding application of fenestrated clips...
