Double arch

Xiao-Qian Li, Zai-Li Zhang, Wen-Fei Tan, Xi-Jia Sun, Hong Ma
Toll-like receptor 4 (TLR4) is important for the pathogenesis of inflammatory reactions and the promotion of pain processing after ischemia/reperfusion (IR) in spinal cord. Recently, C-X-C chemokine ligand 12 (CXCL12) and its receptor, C-X-C chemokine receptor 4 (CXCR4), were demonstrated to be simultaneously critical for inflammatory reactions, thereby facilitating glial activation. However, whether CXCL12/CXCR4 expression can contribute to IR-induced inflammatory pain via spinal TLR4 remained unclear. A rat model was established by 8 min of aortic arch occlusion...

The successful clinical introduction of various non-invasive imaging modalities has contributed to the establishment of 'acute aortic syndrome', a relatively new clinical syndrome incorporating several disease entities with similar clinical features (at the time of clinical presentation). Aortic dissection (AD) with intimal flap and two aortic channels (true and false lumens) is the most important disease entity in acute aortic syndrome. Clinical characteristics of AD have been established, with standardized treatment strategies depending on the affected site of the aorta...

BACKGROUND: How to choose the proximal landing zone in endovascular interventions for a patient with a patent retrograde false lumen in dissection of the ascending aorta and aortic arch remains unclear. This study sought to report the safety and efficiency of inducing thrombosis of the retrograde false lumen to enhance a proximal landing zone to treat retrograde type A aortic dissection. METHODS: This study included 9 patients with retrograde type A aortic dissection treated with a 2-stage operation strategy between January 2015 and January 2016...

OBJECTIVES: Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS: Among 257 children evaluated for tracheobronchial vascular compression, we reviewed the clinical charts for the 59 patients (23%) who underwent surgery...

Many children who are admitted to pediatric hospitals with the chief complaint of apparent life-threatening event (ALTE) are, in fact, well appearing by the time the inpatient medical team evaluates the patient. This presents a diagnostic and therapeutic challenge. We describe a case of a six-month-old full-term female presenting with an ALTE and found to have a double aortic arch, a congenital anomaly that usually presents with a more progressive onset of symptoms such as chronic cough, positional stridor, and feeding difficulties...

Fifth arch anomalies are rare and complex and frequently misdiagnosed or mistaken for other entities. We report a double arch vascular ring that is thought to consist of right fourth arch and left fifth arch components, a previously undescribed persistent fifth arch variant. The currently recognized spectrum and classification of fifth arch vascular anomalies are expanded along with illustrative images to justify the proposed changes. Reviewing and expanding the classification of fifth arch anomalies to include a double arch ring variant will promote recognition, correct diagnosis and appropriate management of these anomalies...

INTRODUCTION: Reconstruction of the soft palate after oncologic resection remains a surgical challenge. Speech and swallowing problems are the consequences of velopharyngeal incompetence following soft palate resection. Free tissue transfer like radial forearm flaps can be used in larger defects for complex reconstruction. The conformation of the flap in order to be closer to the shape of the soft palate improves the functional outcome. In the same way, we describe an original "double-arched" flap design...

A low origin of the radial artery is a rare anatomical variation, with the incidence estimated at 0.2 %. This report presents a previously unrecorded case of an unusual distal origin of the radial artery, co-occurring with a double recurrent radial artery. The radial artery arose under the pronator teres muscle, 76 mm below the intercondylar line of the humerus. After emerging from under the tendon of the pronator teres muscle, the radial artery took a typical course and terminated in the deep palmar arch...

Data from randomized controlled trials (RCTs) demonstrated significant differences between carotid artery stenting (CAS) and carotid endarterectomy (CEA) in terms of early neurological outcomes (from 0 to 30 days), although mid- and long-term neurological results are indistinguishable. CAS in symptomatic standard risk patients is coupled with a higher risk of any stroke, and death or any stroke at 30 days, while the rates of disabling or major stroke do not vary remarkably between treatments. Since the micro-embolization through the stent struts is the primary suspected cause of suspected early postoperative neurological complications (i...

INTRODUCTION: A surgical technique to widen the mandible is the mandibular midline distraction: the most common indications for mandibular midline distraction are severe mandibular anterior crowding, severe mandibular transverse deficiency, uni- or bilateral crossbite, impacted anterior teeth with inadequate space, and tipped teeth. Commonly used distraction devices can be divided into 2 systems: bone-borne distraction system appliance, dental-borne distraction systems. Each system has peculiar advantages, disadvantages, and different indications...

A 48-year-old woman was seen in a surgical outpatient clinic with a 2 year history of progressive dysphagia with occasional regurgitation, partially controlled with a proton pump inhibitor. Primary investigations of pH testing and gastroscopy were normal, although a barium swallow study revealed significant hold-up at the aortic arch impression and a posterior right-sided oesophageal impression suggestive of a right-sided aortic arch. A follow-up computed tomography angiogram discovered a vascular ring encircling the trachea and oesophagus, formed by a right-sided aortic arch with aberrant aortic branches, and a Kommerell's diverticulum...

BACKGROUND: After stroke, patients who suffer from hemiparesis tend to suppress the use of the affected extremity, a condition called learned non-use. Consequently, the lack of training may lead to the progressive deterioration of motor function. Although Constraint-Induced Movement Therapies (CIMT) have shown to be effective in treating this condition, the method presents several limitations, and the high intensity of its protocols severely compromises its adherence. We propose a novel rehabilitation approach called Reinforcement-Induced Movement Therapy (RIMT), which proposes to restore motor function through maximizing arm use...
