BACKGROUND: Coronary artery bypass grafting (CABG) is the standard of care for treating left main coronary lesions. However, recently published randomized controlled trials (RCT) have shown conflicting results. We sought to compare clinical outcomes of percutaneous coronary intervention (PCI) with drug-eluting stent placement to CABG using a meta-analysis of randomized controlled trials. METHODS: A systemic search of Pubmed, Scopus, Cochrane library, and Clinicaltrials...

Regional cerebral oximetry using near-infrared spectroscopy device, an INVOS 5100 C (Medtronic, Minneapolis, MN, USA), during cardiac surgery aims to avoid perioperative neurological impairment, especially during cardiopulmonary bypass. However, it is not uncommon to encounter critically low initial cerebral regional oxygen saturation or a low value unresponsive to intervention. Therefore, it is important to identify factors associated with low saturation value other than true cerebral hypoxia. We investigated the relationship between preoperative regional cerebral oxygen saturation and clinical variables during cardiac surgery...

Short- and long-term neurodevelopmental (ND) disabilities with negative impact on psychosocial and academic performance, quality of life, and independence in adulthood are known to be the most common sequelae for surviving children after surgery for congenital heart disease (CHD). This article reviews influences and risk factors for ND impairment. For a long time, the search for independent risk factors was focused on the perioperative period and modalities of cardiopulmonary bypass (CPB). CPB operations to ensure intraoperative vital organ perfusion and oxygen supply with or without circulatory arrest or regional cerebral perfusion bear specific risks...

INTRODUCTION/PURPOSE: Flow diversion has allowed cerebrovascular neurosurgeons and neurointerventionalists to treat complex, large aneurysms, previously treated with trapping, bypass, and/or parent vessel sacrifice. However, a minority of aneurysms remain that cannot be treated endovascularly, and microsurgical treatment is too dangerous. However, balloon test occlusion (macro and micro), micro WADA testing, ICG, intra-angiography and intra-operative monitoring are all available to clinically test the hypothesis that vessel sacrifice is safe...

BACKGROUND: The management of graft infection following ascending aortic replacement (AAR) and/or aortic valve replacement (AVR) with destruction of the root remains a challenge. Besides technical issues, the choice of graft material is controversial. The study aim was to investigate the initial results of aortic root replacement (ARR) as redo-surgery for infection using the xenopericardial all-biologic conduit (BioIntegral) as an alternative to a homograft or prosthetic material. METHODS: Between February 2013 and January 2015, a total of 18 consecutive patients (16 males, two females; mean age 61 ± 14 years) were reoperated on for infection at a mean of 55 ± 61 months (range: 3 to 219 months) following previous AVR (n = 6), supracoronary aortic replacement (SAR, n = 2), AVR + SAR (n = 1), root replacement (n = 7), and root reconstruction (n = 2)...

INTRODUCTION: Although the benefits of extracranial-intracranial bypass surgery remain controversial, there is some surgical rationale for the augmentation of cerebral blood flow in cases of acute ischemic stroke with hemodynamic instability. CASE REPORT: We report a case of a 62-year-old woman who suddenly developed right hemiplegia and global aphasia. Initial magnetic resonance imaging and magnetic resonance angiography revealed a small acute ischemic lesion in left parietal lobe with occlusion at the left middle cerebral artery...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

BACKGROUND: Complex aneurysms of the anterior cerebral artery (ACA) may require a bypass procedure as part of their surgical management. Most current bypass paradigms recommend technically demanding side-to-side anastomosis of pericallosal arteries or use of interposition grafts, which involve longer ischemia times. The purpose of this study is to assess the feasibility of an anterior temporal artery (ATA) to ACA end-to-side bypass. METHODS: Fourteen cadaveric specimens (17 ATAs) were prepared for surgical simulation...

Many prior investigations have indicated the important role of medical treatment to prevent stroke in patients with intracranial atherosclerosis, with angioplasty and stenting occasionally being performed. In a subgroup of patients with severe hemodynamic impairment, extracranial-intracranial (EC-IC) bypass surgery may be considered. Additionally, in patients with massive infarctions due to middle cerebral artery (MCA) occlusion, the use of decompressive craniectomy may lower mortality rates and improve long-term quality of life...

Moyamoya disease (MMD) is a chronic occlusive cerebrovascular disease characterized by progressive stenosis at the terminal portion of the internal carotid artery and an abnormal vascular network at the base of the brain. Although its etiology is unknown, recent genetic studies have identified RNF213 in the 17q25-ter region as an important susceptibility gene of MMD among East Asian populations. A c.14576G>A polymorphism in RNF213 was identified in 95% of MMD patients with a family history and in 79% of sporadic cases, and patients carrying this polymorphism exhibited significantly earlier disease onset and a more-severe form of MMD...

The development of stent-like devices has increased treatment options for complex internal carotid artery (ICA) aneurysms, but the optimal treatment remains unclear. The purpose of this study was to evaluate the safety and efficacy of endovascular parent-artery occlusion (PAO) for ICA aneurysms. We retrospectively reviewed 28 patients with unruptured ICA aneurysms ⩾10mm treated with PAO between April 2002 and March 2015 at our institution. Patients who developed neurologic symptoms or with venous-phase delay >2s during balloon test occlusion were not treated by PAO...
