[Contrivance to Use Ultrasonic Scalpel for Laparoscopic Surgery during Internal Thoracic Artery Harvest].

From April 2024, manufacturing of short-shaft ultrasonic scalpels( SNGHK) has ceased. A scalpel for laparoscopic surgery (HDH05) remains available;however, its long shaft is unsuitable for internal thoracic artery harvesting through a median sternotomy. We contrived to make the latter device easier to handle using a method that requires no specialized parts.

Repair of mitral paravalvular leak using left atrial appendage tissue.

Paravalvular leak after mitral valve replacement causes serious symptoms such as heart failure and haemolysis. However, whether re-replacement or direct leak site repair is the appropriate surgical treatment for this condition remains controversial. Herein, we describe a case of paravalvular leak repaired using left atrial appendage tissue with excellent results.

Thermoreversible helical fibers from photoreactive triphenylene-derived liquid crystals in liquid paraffin.

Liquid crystalline triphenylene derivatives, (n = 6, 12, 14, 16) were prepared using -alkoxycinnamate as the [2+2] photo-cyclization site. (n = 12, 14, 16) showed Col phase and gave crescent-shaped or helical fibers after UV-irradiated in liquid paraffin solutions at 90 and 110 °C in the Col temperature range. The apparent photoreaction products were shown to be thermally reversible, i.

Development of novel waxy bone haemostatic agents composed of biodegradable polymers with osteogenic-enhancing peptides in rabbit models.

Objectives: The use of bone wax (BW) is controversial for sternal haemostasis because it increases the risk of wound infection and inhibits bone healing. We developed new waxy bone haemostatic agents made from biodegradable polymers containing peptides and evaluated them using rabbit models.

Methods: We designed 2 types of waxy bone haemostatic agents: peptide wax (PW) and non-peptide wax (NPW), which used poly(ε-caprolactone)-based biodegradable polymers with or without an osteogenesis-enhancing peptide, respectively.

Incidence and clinical impact of silent pancreatitis after aortic arch surgery.

Background: This study was designed to investigate the incidence and types of pancreatic injury, risk factors, and time-course changes in computed tomographic findings following total aortic arch replacement with moderate hypothermic circulatory arrest.

Methods: Medical records of patients who underwent total arch replacement between January 2006 and August 2021 were retrospectively reviewed. A comparison study between the patients with (group P) and without pancreatic injury (group N) was conducted to elucidate the impact of pancreatic injury.

Recurrent Mural Thrombosis of the Ascending Aorta in a Patient with Antiphospholipid Syndrome.

A 38-year-old man presented with embolic occlusion of the brachial artery. As per his computed tomography results, a pedunculated mass in the proximal ascending aorta was detected. Since discrimination between a thrombus and a tumor was deemed difficult, the patient underwent replacement of the ascending aorta.

Blood culture-negative endocarditis caused by : a case report.

is well known as a causative organism of cat scratch disease. Although this bacterium infrequently involves the heart, the diagnosis is difficult to confirm. A 75-year-old woman who had a pet cat presented with pancytopenia, hepatosplenomegaly, and low-grade fever.

Inflammatory and immune checkpoint markers are associated with the severity of aortic stenosis.

Objective: Aortic stenosis (AS) is a disease characterized by narrowing of the aortic valve (AV) orifice. In relation to this disease, the purpose of this study was to elucidate the relationships among factors such as expression of programmed cell death-1 ligand (PD-L1, which is the ligand of PD-1 protein; together, they play a central role in the inhibition of T lymphocyte function), clinicopathologic characteristics, infiltrating immune cells, and disease severity.

Methods: We performed immunohistochemical analysis on the surgically-resected AVs of 53 patients with AS.

Asymptomatic Coronary Artery Disease in Japanese Patients With the Acute Ischemic Stroke.

Objective: To investigate the prevalence and outcomes of asymptomatic coronary artery disease (CAD) in patients with the first episode of ischemic stroke.

Methods: Patients admitted to our hospital between November 2001 and January 2009 for the episode of an acute ischemic stroke/transient ischemic attack were included. Stress-Tl-201 scintigraphy was performed and followed by coronary angiography (CAG).

Bridge use of endovascular repair and delayed open operation for infected aneurysm of aortic arch.

We present the first clinical report of the successful treatment of an infected thoracic aortic arch aneurysm with the use of endovascular repair as a bridge to second-stage open operation. A 70-year-old patient underwent urgent endovascular repair through the right femoral approach because of a diagnosis of sepsis and impending rupture of an infected thoracic aortic arch aneurysm. After 2 weeks of medical treatment, we successfully performed explantation of the stent graft, wide debridement of the surrounding tissue, and in-situ replacement using a rifampicin-bonded four-branched prosthetic graft with omental flap.

Direct protection by a gonadotropin-releasing hormone analog from doxorubicin-induced granulosa cell damage.

Background/aims: Recent clinical applications suggest a beneficial effect of gonadotropin-releasing hormone analog (GnRHa) as a gonadal protector from chemotherapy-induced premature ovarian failure. This study aimed to determine cellular mechanisms involved in the protective action of GnRHa against granulosa cell damage caused by doxorubicin.

Methods: Granulosa cells were obtained by ultrasound-guided follicular aspiration from patients undergoing in vitro fertilization, and screened for GnRH receptor expression prior to analyses.

Mixed connective tissue disease associated with antineutrophil cytoplasmic antibodies against proteinase-3 and systemic atherosclerosis: a case report.

A 47-year-old woman presented with facial spasm, swollen fingers and Raynaud's phenomenon due to cerebrovascular disorder and mixed connective tissue disease (MCTD). Although she was positive for both antineutrophil cytoplasmic antibodies against proteinase-3 (PR3-ANCA) and anti-U1 RNP antibodies, she did not meet the American College of Rheumatology classification criteria for Wegener's granulomatosis (WG). Physical and histopathological examinations revealed severe systemic atherosclerosis without any of the traditional risk factors.
