the high blood rate that often occurs in arteries may play a role in artery failure and tortuosity which leads to blackouts, transitory ischemic attacks and other diseases. however, vibration and instability analysis of carotid arteries are lacking. the objective of this study is to investigate the vibration and instability of the carotid arteries conveying blood under axial tension with surrou...

A 56-year-old man presented with a 3-month history of progressive dizziness. His dizziness was aggravated when his head was rotated to the right side. Diagnostic angiography showed that a normal right-sided vertebral artery in the neutral position became an abnormal vertebral artery with two stenotic lesions at the C3-4 and C5-6 levels when the patient's head was turned to the right. A normal l...

A 17-year old man was referred with Syncope. Echocardiography suggested a mass in the main pulmonary artery. A comprehensive cardiac magnetic resonance was performed. The mass was attached to the intima of the pulmonary artery. The diagnosis of thrombus was excluded. Finally, the mass was resected successfully and pathology confirmed the diagnosis (Fig. 1, Supplementary Videos S1 and S2). Suppl...

Introduction Percutaneous coronary intervention (PCI) has become the treatment of choice for patients with symptomatic one-vessel coronary artery disease especially when they fail medical therapy alone. Guide catheter support is essential to perform PCI. Transfemoral access is the most commonly used access for PCI. Most guide catheter shapes are designed to allow co-axial engagement from the fe...

INTRODUCTION Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. DIAGNOSIS Precise diagnosis of dissection of the cervical artery--carotid or vertebral--is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. TR...

Lewy bodies in Alzheimer's disease: a neuropathological review of 145 cases using alpha-synuclein immunohistochemistry. Lewy body pathology in familial Alzheimer's disease: evidence for disease and mutation-specific pathologic phenotype. Lewy body pathology in late-onset familial Alzheime...

OBJECTIVE: To determine a reference curve for the peak systolic velocity of fetal middle cerebral artery. MATERIALS AND METHODS: The authors developed a cross-sectional study with 143 healthy pregnant women between the 23rd and 35th gestational weeks. A bidimensional axial scan of the fetal skull was performed, including the thalami and pellucid septum. Subsequently, the middle cerebral artery ...

A78-year-old woman was admitted with chest pain. Coronary angiography revealed a normal right coronary artery. The left coronary artery (LCA) could not be intubated and was not possible to demonstrate on right coron...

Axial length (AL) is a significant indicator of eyeball development, but reports on the overall status of axial development in congenital cataract (CC) patients and its relationship with patient demographics, such as age, sex, and laterality, are rare. We prospectively investigated the AL of 1,586 patients ≤ 18 years old and undergoing cataract surgery in China from January 2005 to December 201...

The angularis oris axial pattern flap is based on the blood supply of the angularis oris artery and vein. While the use of this flap for repair of canine facial wounds is well documented, this technique has not been reported in the cat. This case report presents the reconstruction of a large ventral chin and rostral lip wound with the use of this flap. Complete survival of this flap was observe...
