OBJECTIVES: Neonates with congenital heart disease may have an increased risk of cerebral sinovenous thrombosis, but incidence rates are lacking. This study describes the clinical and neuroimaging characteristics of cerebral sinovenous thrombosis in neonates undergoing cardiac surgery. METHODS: Forty neonates (78% male) requiring neonatal univentricular or biventricular cardiac repair using cardiopulmonary bypass were included. All underwent preoperative (median postnatal day 7) and postoperative (median postoperative day 7) magnetic resonance imaging of the brain, including venography, to detect cerebral sinovenous thrombosis...

The cerebral hypoperfusion caused by chronic progressive stenosis or occlusion of intracranial arteries in moyamoya disease can be treated by direct bypass or indirect revascularization procedures. The extent of collaterals from the external carotid artery (ECA) after indirect revascularization surgery is the key point of angiographic follow-up, and the invasiveness of angiography impelled us to investigate the role of ultrasonography in the evaluation of collaterals. We hypothesized that the collaterals shown on angiography might produce corresponding hemodynamic changes in color Doppler ultrasonography...

Objective Acute kidney injury (AKI) is a common complication after cardiac surgery and is associated with significant morbidity and mortality. Near infrared spectroscopy (NIRS) is a noninvasive technique for real-time measurement of cerebral tissue oxygenation. The purpose of the present study was to evaluate the correlation of AKI with hemoglobin and regional cerebral oxygen saturation (rScO2) measured intraoperatively and postoperatively in patients undergoing cardiac surgery. Methods We retrospectively analyzed the prospectively collected data of 45 adult patients with normal renal function who underwent isolated coronary artery bypass grafting (CABG) from January 2014 to May 2014...

Background: Clinical assessment reveals that patients after surgery of cardiopulmonary bypass or coronary bypass experience postoperative cognitive dysfunction. This study aimed to investigate whether resuscitation after a hemorrhagic shock (HS) and/or mild cerebral ischemia caused by a unilateral common carotid artery occlusion (UCCAO) can cause brain injury and concomitant neurological dysfunction, and explore the potential mechanisms. Methods: Blood withdrawal (6 mL/100 g body weight) for 60 min through the right jugular vein catheter-induced an HS...

OBJECTIVES: Although strict blood glucose control during cardiovascular surgery is essential to avoid postoperative complications, the various changes in glucose levels that occur during surgery have not been investigated in detail. In this study, we continuously monitored blood glucose changes during aortic surgery using the STG-55Ⓡ artificial endocrine pancreas (Nikkiso Inc., Tokyo). METHODS: Between December 2015 and 2016, we performed continuous blood glucose monitoring in 22 patients (14 men and 8 women, 72 ± 11 years old), who required hypothermic circulatory arrest during an ascending/aortic arch surgery, at the Jichi Medical University Hospital...

BACKGROUND: Over the past decade, there has been a revival and a renewed interest for cerebrovascular bypass procedures. The superficial temporal artery (STA) has its value as a reliable donor vessel; however, a possible role for the middle meningeal artery (MMA) as a donor artery is still unclear. OBJECTIVE: To assess the feasibility of using the MMA as a donor vessel in cerebrovascular surgery. METHODS: We performed cadaveric dissections on 12 fresh specimens (23 sides) after bilateral silicone injection into the internal and external carotid arteries...

Many employees in the aluminum industry are exposed to a range of aluminum compounds by inhalation, and the presence of ultrafine particles in the workplace has become a concern to occupational health professionals. Some metal salts and metal oxides have been shown to enter the brain through the olfactory route, bypassing the blood-brain barrier, but few studies have examined whether aluminum compounds also use this pathway. In this context, we sought to determine whether aluminum was found in rat olfactory bulbs and whether its transfer depended on physicochemical characteristics such as solubility and granulometry...

Aortic arch hypoplasia is commonly present in neonates born with ductal-dependant coarctation of the aorta. The ideal surgical repair of neonates with proximal arch hypoplasia continues to be debated. Controversy exists about the fate of the hypoplastic proximal aortic arch following surgical repair and whether that will eventually grow to normal size upon relief of the distal obstruction or will persist as a residual lesion that can affect long-term outlook of those patients. There is new evidence that residual proximal arch hypoplasia and the shape of the reconstructed arch both have an important impact on vascular remodelling and subsequent development of hypertension...

Femoro-femoral cardiopulmonary bypass (CPB) followed by deep hypothermic circulatory arrest is one of the modalities used for ascending aortic pseudoaneurysm repair to achieve cardiac unloading and to avoid severe hemorrhage due to the risk of rupture during the sternal entry. However, due to the limited size of the cannulas, it can be challenging to achieve total cardiopulmonary support. Therefore, despite the achievement of total cardiopulmonary support, the heart may still be able to eject antegrade blood flow that meets the retrograde blood flow from the arterial side of the CPB...

Pure fusiform aneurysms without dissection are considered to have a low risk of rupture. Furthermore, aneurysm wall with atherosclerotic change tends to be less susceptible to rupture. We present a rare case of multiple atherosclerotic fusiform aneurysms associated with repeated subarachnoid hemorrhage(SAH)during a 9-year observation period. A 34-year-old woman was admitted to our hospital because of SAH. SAH with a temporal hematoma due to a fusiform aneurysm of the right middle cerebral artery(MCA)was detected using computed tomography(CT)...

BACKGROUND: In this study, the risk factors for stroke after coronary artery bypass grafting (CABG) were examined. In particular, the role of asymptomatic carotid artery stenosis (both unilateral and bilateral) as a predictor of in-hospital postoperative stroke was investigated. Finally, the trends surrounding in-hospital postoperative stroke from 1999 to 2011 also were examined. The purpose of the study was to appropriately identify patients at high risk for stroke after CABG and spark discussion about the perioperative management of such patients...

BACKGROUND: Total aortic arch replacement (TOTAL) is a complicated operation and has traditionally required deep hypothermic circulatory arrest. In this study, the impact of moderate hypothermic circulatory arrest (MHCA) and antegrade cerebral perfusion (ACP) for TOTAL were examined. METHODS: The ARCH International aortic database was queried and 3,265 patients undergoing TOTAL using ACP were identified. Patients were divided into groups based on lowest cooling temperature: MHCA (20° to 28°C) or deep hypothermia (DHCA) (12° to 20°C)...

OBJECTIVES: The best surgical strategy for acute Stanford Type A aortic dissection (aTAAD) involving the arch remains controversial. Here, we report on the satisfactory results following aTAAD repair using a novel arch fenestrated stent graft. METHODS: From December 2014 to December 2015, 42 aTAAD patients (27 male and 15 female) underwent ascending aorta replacement and fenestrated stent graft implantation. The fenestrated stent graft was implanted into the true lumen of the aortic arch and proximal descending aorta, with the fenestration opening located at the ostia of 3 head vessels in the arch...

Cardiopulmonary bypass surgery is associated with a high incidence of neurological complications, including stroke, delirium and cognitive impairment. The development of strategies to reduce the incidence of such neurological events has been hampered by the lack of a clear understanding of their pathophysiology. Cerebral autoregulation (CA), which describes the ability of the brain to maintain a stable cerebral blood flow over a wide range of cerebral perfusion pressures despite changes in blood pressure, is known to be impaired in various neurological disorders...

BACKGROUND: Mood disorders, depression, and loneliness are established risk factors for thrombotic occlusions. Social relationships in general, and marital status in particular may play a role in predicting cardiovascular outcomes and survival after ST-segment elevation myocardial infarction (STEMI), but the evidence is inconclusive especially in Asians. METHODS: The Korean patients presented with STEMI (n=980) constituted married (n=780); or widowed, divorced, or single (WDS, n=200) groups...

The current European Society of Cardiology (ESC) guidelines on peripheral arterial diseases include recommendations on diagnostics and treatment of atherosclerotic manifestations in peripheral arteries. Because of the high coincidence of atherosclerosis in different arterial territories, screening for other atherosclerotic lesions is necessary in patients with clinical symptoms in one vascular bed. Consistent treatment of cardiovascular risk factors is important in all patients with peripheral atherosclerosis...
