The carotid-cavernous fistula (CCF) is a rare complication in patients victimized by craniofacial trauma. It involves multidisciplinary medical action. Owing to its potential complications, it is essential that maxillofacial surgery and neurosurgery specialists diagnose this condition so that appropriate treatment can be performed. The authors present a report of a case 11 years after the surgery.

This paper presents the latest in vivo findings of a novel vascular coupling system. Vascular anastomosis is a common procedure in reconstructive surgeries and traditional hand suturing is very time consuming. The vascular coupling system described herein was designed to be used on arteries for a rapid and error-free anastomosis. The system consists of an engaging ring made from high density polyethylene using computer numerical control machining and a back ring made from polymethylmethacrylate using laser cutting...

BACKGROUND: A pathergy reaction is defined as a hyperreactivity of the skin in response to minimal trauma, which is important in the diagnosis of Behçet's disease (BD). However, a pathergy reaction may not be restricted to the skin, and little is known about whether an invasive medical procedure can induce the reaction. Here we present a pathergy reaction induced by renal biopsy, an invasive procedure. CASE PRESENTATION: A 46-year-old man who was diagnosed with IgA vasculitis (IgAV) at the age of 38 was treated with prednisolone and mizoribine...

INTRODUCTION: TEVAR has largely replaced traditional open aortic repair for anatomically suitable lesions, however, long-term outcomes are unknown. METHODS: All patients who underwent TEVAR from December 2004-October 2015 at a single tertiary care institution were included. Demographics, injury pattern, operative details, outcomes, and surveillance were reviewed. Follow-up ranged from 2-132 months, and was obtained from clinic notes and imaging reports. RESULTS: A total of 88 patients underwent TEVAR; all suffered from blunt mechanisms, 72...

Free tissue transfer has been increasingly used in clinical practice since the 1970s, allowing reconstruction of complex and otherwise untreatable defects resulting from tumor extirpation, trauma, infections, malformations or burns. Free flaps are particularly useful for reconstructing highly complex anatomical regions, like those of the head and neck, the hand, the foot and the perineum. Moreover, basic and translational research in the area of free tissue transfer is of great clinical potential. Notwithstanding, surgical trainees and researchers are frequently deterred from using microsurgical models of tissue transfer, due to lack of information regarding the technical aspects involved in the operative procedures...

BACKGROUND: Blunt cerebrovascular injury (BCVI) was underdiagnosed until the 1990s when blunt carotid injuries were found to be more common than historically described. Technological advancements and regionalization of trauma care have resulted in increased screening and improved diagnosis of BCVI. The aim of this study was to demonstrate that systematic evaluation of the screening and diagnosis of BCVI, combined with early and aggressive treatment, have led to reductions in BCVI-related stroke and mortality...

Identifying the site of vascular bleeding in fatal cases of traumatic basal subarachnoid hemorrhage (TBSAH) is important, but can be very difficult to achieve when there is extensive blood clot in the posterior cranial fossa. Post mortem angiography in these circumstances has been reported previously but with mixed results, and is rarely used in current practice within the United Kingdom. We have developed a simple and effective post mortem angiography method, using fluoroscopy and clear modern contrast medium, suitable for use in the autopsy room...

INTRODUCTION: Cervical artery dissection (CAD) is responsible for up to 20% of all ischaemic strokes in patients younger than 45. The benefits of acute-phase reperfusion therapy in these patients have yet to be confirmed. METHODS: We conducted a retrospective review of patients with CAD admitted to a comprehensive stroke centre between 2010 and 2015. We recorded baseline clinical characteristics, treatments, functional outcomes, and mortality. RESULTS: We identified 35 cases of CAD (23 carotid/12 vertebral); mean age was 43...

: Mitochondria play a variety of functional roles in cortical neurons, from metabolic support and neuroprotection to the release of cytokines that trigger apoptosis. In dendrites, mitochondrial structure is closely linked to their function, and fragmentation (fission) of the normally elongated mitochondria indicates loss of their function under pathological conditions, such as stroke and brain trauma. Using in vivo two-photon microscopy in mouse brain, we quantified mitochondrial fragmentation in a full spectrum of cortical injuries, ranging from severe to mild...

INTRODUCTION: Traumatic intracranial aneurysms in children are rare and may occur as the result of closed or penetrating head trauma. Their natural history seems to be more aggressive. Most traumatic aneurysms have complex shape, tending to have a large neck or even a fusiform morphology. CASE REPORT: We present a case of a traumatic carotid artery aneurysm in a 9-year-old girl that was successfully treated with pipeline embolization device. DISCUSSION: Due to its dissecting nature, wall friability and lack of a substantial neck can make surgical clipping and selective coiling difficult and risky...

Fibromuscular dysplasia (FMD) is a rare, segmental, nonatheromatous, and noninflammatory arterial disease of unknown etiology. It predominantly involves renal artery (60-75%) followed by extracranial part of the internal carotid artery and vertebral arteries (25-30%). The disease typically affects middle-aged women and involves intermediate-sized arteries throughout the body. There are rare case reports of extracranial FMD compounding a trauma case. A patient was brought to trauma center emergency with a history of fall from height...

BACKGROUND: Prenatal alcohol exposure (PAE) can result in physical and neurocognitive deficits that are collectively termed "fetal alcohol spectrum disorders" (FASD). Although FASD is associated with lifelong intellectual disability, the mechanisms mediating the emergence of secondary mental health and physical disabilities are poorly understood. Based on our previous data showing that maternal ethanol (EtOH) exposure in mice resulted in an immediate reduction in cranially directed fetal blood flow, we hypothesized that such exposure would also result in persistent alterations in cranially directed blood flow in the prenatally alcohol-exposed (PAE) adult...

BACKGROUND: The goal of the treatment of direct carotid cavernous fistula (CCF) is to occlude the arteriovenous shunt and to preserve the patency of the concerned internal carotid artery. However, for the ipsilateral posttraumatic fragile cerebrum, coil embolization plus parent artery occlusion for the high-flow direct CCF is better for the prevention of hyperperfusion syndrome and intracranial hemorrhage. We experienced such a case and managed it successfully. CASE DESCRIPTION: A 6-year-old boy had severe head trauma caused by being hit by a car...

BACKGROUND: The best management of carotid artery dissection (CAD) is still controversial ranging from antiplatelet medication to open surgery or endovascular treatment. In this retrospective study, we assessed the safety and efficacy of endovascular stent angioplasty for the treatment of CAD. METHODS: From February 2006 to February 2016, 44 patients (28 women and 16 men, age range 25-65 years, mean 42) with CAD were included in this study. The internal carotid artery dissection was spontaneous in 32 patients and posttraumatic in the remaining 12 (in 1 case, it was bilateral)...

Penetrating neck trauma is most commonly caused by firearm discharge, and is potentially very dangerous, being associated with a high risk of mortality. A 12-year-old patient with a recent history of a gunshot wound to the neck was evaluated in detail; a bullet was located in close proximity to the left common carotid artery. Neck exploration was performed and the foreign body was removed without any complications. The management of the patient is discussed, as are contemporary approaches to the treatment of penetrating neck trauma...

Temporal bone fractures can occur as a result of various head trauma. The most common cause of the hemotympanum is traumatic temporal bone fracture. Facial paralysis and hearing loss can be seen associated with temporal bone fracture. The development of the internal carotid artery aneurysm after temporal bone fracture is extremely rare. In this article, the authors evaluated carotid artery aneurysm that developed after temporal fracture and aneurism compressed by coagulated blood mass which showed itself as a hemotympanum...

: The aim of this case report is to be aware of occult carotid lesions in thoracic- abdominal trauma because, carotid artery injury consequent to blunt trauma is rare, affecting less than 1% of patients as reported in literature. A 45-years-old female, involved in a traffic accident, arrived to Emergency Room hemodynamically stable, with a Glasgow Coma Scale of 15, complaining abdominal pain, without any neurological signs. She underwent Computed Tomography (CT) scan that showed a complete disruption of left abdominal wall muscles, associated with massive bowel loops herniation...

As classically described, Eagle syndrome is an entity where patients develop pain or neurologic manifestations arising from an elongated styloid process and/or an ossified stylohyoid ligament irritating or compressing adjacent cranial nerves or the carotid arteries. Over the past few years, there have been reports of actual injury to the internal carotid artery with dissection, occlusion and strokes. We present three cases identified after blunt trauma-one due to carotid compression and two due to actual injury to the internal carotid artery...
