To observe the mid- and long-term result of intentional coverage of celiac artery in thoracic endovascular aortic repair (TEVAR) surgery for aortic dissection.
 Methods: We retrospectively analyzed 21 cases who received TEVAR with celiac artery coverage during the operation. The existence of collaterals between celiac artery (CA) and superior mesenteric artery (SMA) was confirmed by preoperative CT angiography (CTA) or digital substract angiography (DSA) for each patient. We used the stent-graft precisely above the orifice of SMA...

BACKGROUND: Cardioplegic solutions are the standard in myocardial protection during cardiac surgery, since they interrupt the electro-mechanical activity of the heart and protect it from ischemia during aortic cross-clamping. Nevertheless, myocardial damage has a strong clinical impact. We tested the hypothesis that the short-acting beta-blocker esmolol, given immediately before cardiopulmonary bypass and as a cardioplegia additive, would provide an extra protection to myocardial tissue during cardiopulmonary bypass by virtually reducing myocardial activity and, therefore, oxygen consumption to zero...

The most common histological classification of bile duct cancer is adenocarcinoma and squamous cell carcinoma (SCC) is relatively rare. We report a case of a 78-year-old man with SCC of the extrahepatic bile duct associated with metachronous para-aortic lymph node metastasis. He had undergone subtotal stomach-preserving pancreatoduodenectomy. The pathological findings demonstrated moderately differentiated SCC of the distal extrahepatic bile duct (T1N1M0, stage IIB). 6 months after surgery, recurrence of the para-aortic lymph node was shown in abdominal CT...

Anesthesia for patients with moderate aortic stenosis accompanied by atrial fibrillation during high-risk surgery such as liver transplantation remains a challenge in maintaining control of heart rate and maintenance of cardiac output. The action of terlipressin on vasopressin receptors (mainly V1 receptors) leads to splanchnic vasoconstriction and is the key mechanism responsible for increasing systemic vascular resistance and reducing heart rate. We report successful anesthetic management using low-dose terlipressin infusion in an elderly patient who had moderate aortic stenosis with atrial fibrillation during urgent deceased-donor liver transplantation...

The maximum rate of pressure rise (dP/dtmax) in radial artery has been proposed as a noninvasive surrogate of aortic dp/dtmax, reflecting left ventricular (LV) contractility in children. The aim of this study was to investigate relationship between aortic and radial dp/dtmax at weaning from cardiopulmonary bypass (CPB) and usefulness of these indices for estimating postoperative outcomes in pediatric congenital heart surgery.Aortic and radial arterial pressure waveforms were analyzed simultaneously during weaning from CPB in 29 congenital heart surgery...

BACKGROUND: Direct vertebral rotation (DVR) has gained increasing popularity for deformity correction surgery. Despite large moments applied intraoperatively during deformity correction and failure reports including screw plow, aortic abutment, and pedicle fracture, to our knowledge, the strength of thoracic spines has been unknown. Moreover, the rotational response of thoracic spines under such large torques has been unknown. PURPOSE: Simulate DVR surgical conditions to measure torsion to failure on thoracic spines and assess surgical forces...

OBJECTIVE: The term frailty is frequently used during decision-making in transcatheter heart valve procedures. Nevertheless, frailty is still measured by eyeballing rather than by using standardized frailty assessments. In a previous study, we developed a frailty score in a cardiac surgical patient population including patients, who underwent transcatheter aortic valve replacement (TAVR). Here, we present the results from the subsequent validation study focusing on the TAVR cohort. METHODS: One hundred thirty patients underwent TAVR...

Accuracy of prediction of pelvic lymph node status using sentinel lymph node biopsy (SLNB), and outcomes of SLNB-guided abdominal radical trachelectomy (ART) were assessed. Patients with stage IB1 (Figure 2009) cervical cancer and with tumors >2 cm were enrolled. Prior to fertility-sparing surgery 99mTc-labeled phytate was administered. SLNs were intraoperatively identified, excised, and assessed using fast-frozen sections. Systematic bilateral pelvic lymphadenectomy with or without para-aortic lymphadenectomy was subsequently undertaken...

BACKGROUND: Aortic valve replacement with stentless bioprostheses has been shown to produce lower aortic gradients than stented bioprostheses, thus facilitating left ventricular mass regression and preventing heart failure. We sought to determine the long-term results of stentless biological aortic valve replacement over a 17-year follow-up. METHODS: Between 1996 and 2012, 2551 patients underwent isolated aortic valve replacement with a stentless prosthesis (Medtronic Freestyle) at a single center...

REVIEW
Hitoshi Matsuda
Hospital mortality after the replacement of chronic type B aortic dissection is around 8-10% and adverse outcomes include paraplegia and stroke. However, the level of evidence for indication of thoracic endovascular aortic repair (TEVAR) for type B chronic aortic dissection is Class IIa. Results of the INSTEAD-XL trial have verified that preemptive TEVAR for uncomplicated type B aortic dissection improves prognosis. The indication for this procedure is reportedly a maximum aortic diameter >40 mm during the acute phase and a patent primary entry site in the thoracic aorta, while the optimal timing for TEVAR would be the subacute phase, from 2 weeks to 3-6 months after onset...

Staphylococcus lugdunensis (S. lugdunensis) is a coagulase negative staphylococcus (CoNS) that can cause destructive infective endocarditis. S. lugdunensis, unlike other CoNS, should be considered to be a pathogen. We report the first case of S. lugdunensis endocarditis causing ventricular septal defect and destruction of the aortic and mitral valves. A 53-year-old male with morbid obesity and COPD presented with intermittent fever and progressive shortness of breath for 2 weeks. Chest examination showed bilateral basal crepitations, and a grade 2 systolic murmur along the right sternal border...

Poor dentition and/or dental infection due to insufficient oral care are presumed to be risk factors for infective endocarditis (IE). We present a case of endocarditis caused by Granulicatella adiacens and Sjögren's syndrome (SS) with oral complications diagnosed simultaneously. A 67-year-old woman was admitted to our hospital with fever, general fatigue, arthralgia, and back pain. She was diagnosed with primary SS according to the criteria of the American-European Consensus Group. Transthoracic echocardiography carried out to examine her persistent fever revealed vegetation formation (14 × 5 mm) on the aortic valve and her blood cultures were positive for G...

We present the case of a 52-year-old woman who presented to the emergency department with chest and neck pain. Initial cervical spine magnetic resonance imaging shows an abnormal flow void in the left vertebral artery, which prompted a computed tomographic angiogram. This demonstrated a hyperdense thickened ascending aortic wall, which extended into the great vessel origins. Clinically and radiographically interpreted as an acute aortic syndrome and/or intramural hematoma, the patient underwent ascending aortic repair with graft...

BACKGROUND: Spinal cord ischemia (SCI) leads to variable degrees of neurologic deficit in patients undergoing major cardiovascular surgery. The effect of intraoperative neuroprotection against SCI and the subsequent ischemia-reperfusion injury is still limited. Because isoflurane is a commonly used anesthetic agent during major operation, and its neuroprotective and neurotoxicity effects have both been discussed, this study aimed to investigate the effect of isoflurane on the spinal cord's functional recovery in a rat model of cord ischemia...
