1/300. Diagnostic and therapeutic management of bilateral carotid artery occlusion caused by near-suicidal hanging.In cases of attempted suicide by hanging, a combination of mechanisms causing local destruction of the pharynx, larynx, vessels, and spine, as well as neurologic complications, has to be considered. We present a case of hanging in which a deeply unconscious patient without any palpaple pulsation of the carotid arteries was referred to our otolaryngology department. Computed tomography and angiography showed parapharyngeal air, complete obstruction of both common carotid arteries, and a compensatory circulation through the vertebral arteries. Three hours after the trauma, surgical exploration with resection of the enrolled intima of both carotid arteries and repair of the pharynx was performed. The patient awoke with an infarct of the right hemisphere with incomplete left hemiparesis the next day, but symptoms slowly declined during the following months, and the patient learned swallowing again perfectly. We conclude from our experience that in near-hanged patients a prompt onset of adequate diagnostic and therapeutic measures is mandatory, as good neurologic and functional results may occur even in cases with coma and severe destruction of the carotid arteries and pharyngeal and laryngeal structures. Surgical repair of blunt carotid lesions is recommended and may be crucial for a good outcome.- - - - - - - - - - ranking = 1keywords = trauma (Clic here for more details about this article) |
2/300. Accidental decapitation: an unusual injury to a passenger in a vehicle.A case of decapitation of a vehicle passenger in an accident on a highway is reported. Evaluation of roadside evidence and the deceased's injuries revealed that the victim was partially ejected from a broken passenger-side window as the vehicle spun out of control, decapitation being due to the impact of his head against a barrier stanchion on the shoulder of the road. An unfastened seat-belt, high-speed driving and the construction of the road barrier were contributory factors.- - - - - - - - - - ranking = 604.0535666172keywords = injury (Clic here for more details about this article) |
3/300. Traumatic dissection of the common carotid artery after blunt injury to the neck.BACKGROUND: Occlusive lesions of the common carotid artery (CCA) resulting from blunt injury are extremely rare, and their clinicopathologic and therapeutic features have not yet been clarified. OBJECTIVES AND RESULTS: Five patients with occlusive lesions of the CCA developed neurologic deficits at 1.5 hours to 10 years after blunt neck injury. Lesions included two complete occlusions, one severe stenosis, and two segmental intimal dissections of the CCA. In the two patients with CCA occlusion, bypass surgery was performed using a Dacron graft between the ipsilateral subclavian artery and the carotid bifurcation. In the remaining three patients, the involved segments were replaced with a Dacron graft. Surgical specimens from the early posttraumatic period revealed intimal tears with mural thrombosis and/or subintimal hematomas and those from the later period showed myointimal hyperplasia or fibrotic organization. CONCLUSION: Traumatic occlusive lesions of the CCA tend to evolve from intimal dissections to severe stenoses or occlusion, compromising cerebral circulation. The involved CCA can be diagnosed early by B-mode Doppler sonography and successfully reconstructed using a Dacron graft.- - - - - - - - - - ranking = 907.0803499258keywords = injury, trauma (Clic here for more details about this article) |
4/300. Isolated longitudinal rupture of the posterior tracheal wall following blunt neck trauma.The authors report 3 female children (4, 5 and 12 years old) who suffered an isolated rupture of the posterior tracheal wall (membranous part) following a minimal blunt trauma of the neck. Such tracheal ruptures often cause a mediastinal and a cutaneous thoraco-cervical emphysema, and can also be combined with a pneumothorax. The following diagnostic steps are necessary: X-ray and CT of the chest, tracheo-bronchoscopy and esophagoscopy. The most important examination is the tracheo-bronchoscopy to visualize especially the posterior wall of the trachea. Proper treatment of an isolated rupture of the posterior tracheal wall requires knowledge about the injury mechanisms. The decision concerning conservative treatment or a surgical intervention is discussed. In our 3 patients we chose the conservative approach for the following reasons: 1) The lesions of the posterior tracheal wall were relatively small (1 cm, 1.5 cm, 3 cm) and showed a good adaptation of the wound margins. 2) No cases showed an associated injury of the esophageal wall. All of our patients had an uneventful recovery, the lesion healed within 10 to 14 days, and follow-up showed no late complications.- - - - - - - - - - ranking = 307.0267833086keywords = injury, trauma (Clic here for more details about this article) |
5/300. Cervical myositis ossificans traumatica: a rare location.An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare.- - - - - - - - - - ranking = 7keywords = trauma (Clic here for more details about this article) |
6/300. Delayed post-traumatic cervical instability.BACKGROUND: Cervical spine instability is a clinical entity whose biomechanical and radiological features have been widely discussed by many authors. On the other hand, the subject of delayed post-traumatic cervical instability is often surrounded by confusion due to its difficult nosologic framing; the aim of this study is to contribute to the matter. methods: A cooperative study was organized by the Study Group for Spinal Surgery of the Italian Society of neurosurgery to evaluate cervical trauma patients surgically treated more than 20 days after the traumatic event. From a total number of 172 patients, twenty-five were admitted to the study, because neuroradiological investigations performed during the acute phase had shown either an absence of traumatic lesions or only minimal lesions judged to be stable. For this reason these 25 patients had not been treated by either surgery or immobilization in a halo vest. Some time after trauma, this group of patients clearly demonstrated evidence of unstable lesions requiring surgical treatment, following the appearance of new clinical signs or on neuroradiological follow-up. RESULTS: Re-examination of the neuroradiological investigations performed during the acute phase made it possible to identify elements that might have led us to suspect the presence of ligamental lesions: microfractures, dislocations less than 3 mm, and inversion of physiological lordosis. CONCLUSIONS: This review clearly indicates that patients with even mild cervical trauma must be scrupulously evaluated during the acute phase and that in some cases it is advisable to perform a more detailed neuroradiological investigation.- - - - - - - - - - ranking = 10keywords = trauma (Clic here for more details about this article) |
7/300. Multivascular trauma on an adolescent. Perioperative management.Penetrating vascular injury, in particular at the neck, is a life-threatening trauma not only of the nature and the anatomic proximity of cardiovascular, aerodigestive, glandular and neurologic system but also of the development of early and late complications. The following case report describes our experience with a penetrating wound patient, who was admitted to our emergencies twelve hours after the accident. The only demonstrable objective signs included a large hematoma at the right-side of the neck and distended mediastinum on the chest X-ray. As the patient was cardiovascularly unstable he was immediately transported to the theater without any angiography. The mandatory operative exploration was initially unsuccessful and a median sternotomy with a standard cardiopulmonary bypass and deep hypothermia circulatory arrest was established to restore all the vascular lesions. Actually, the patient was in critical condition with a rupture of the right internal jugular vein, a large pseudoaneurysm of the innominate artery and an avulsion of the ascending aorta with the suspicion of a cardiac tamponade. The postoperative period lasted two full months, while complications appeared. The substantial message from this multivascular trauma is the early diagnosis of the life-threatening complications as exsanguinations, ventricular fibrillation and the ability to minimize postoperative complications, which will impair the normal functional life of the patient.- - - - - - - - - - ranking = 157.0133916543keywords = injury, trauma (Clic here for more details about this article) |
8/300. thyroid gland hematoma after blunt cervical trauma.Thyroid hematoma is a rare cause of airway obstruction in victims of blunt trauma. The case of a 34-year-old woman who developed orthopnea after a low-energy motor vehicle accident is described. Presenting greater than 24 hours after her accident, the patient noted dysphagia, tracheal deviation, and postural dyspnea. The diagnosis of thyroid gland hematoma was made with a combination of fiberoptic laryngoscopy, cervical computed tomography, and great vessel and carotid angiography. Invasive airway management was not required. The patient underwent a total thyroidectomy and recovered without complications.- - - - - - - - - - ranking = 5keywords = trauma (Clic here for more details about this article) |
9/300. Fatal laryngeal injury in an achondroplastic dwarf secondary to airbag deployment.We report the case of an unrestrained driver with achondroplastic dwarfism who suffered a fatal anterior neck injury when her airbag deployed as she rear-ended another vehicle at 30-40 mph. Her short stature and short limbs required her to sit within a handbreadth of the steering wheel, which probably allowed the airbag or airbag cover to strike her neck as it opened. This is the first reported case of fatal injury to a driver with achondroplastic dwarfism.- - - - - - - - - - ranking = 906.0803499258keywords = injury (Clic here for more details about this article) |
10/300. Spinal intradural arachnoid cysts located anterior to the cervical spinal cord. Report of two cases and review of the literature.The authors describe two rare occurrences of radiographically, surgically, and pathologically confirmed spinal intradural arachnoid cysts (not associated with additional pathological entities) that were located anterior to the cervical spinal cord. These lesions have been reported previously in only eight patients. The patients described in this report were young adults who presented with progressive spastic tetraparesis shortly after sustaining mild cervical trauma and in whom no neurological deficit or bone fracture was demonstrated. The presence of an intradural arachnoid cyst was detected on postcontrast computerized tomography (CT) myelography and on magnetic resonance imaging; both diagnostic tools correctly characterized the cystic nature of the lesion. Plain radiography, plain tomography, and contrast-enhanced CT scans were not diagnostic. In both cases a laminectomy was performed, and the wall of the cyst was excised and fenestrated with subarachnoid space. Postoperatively, the patients made complete neurological recoveries. Based on a review of the literature, arachnoid cysts of the spinal canal may be classified as either extra- or intradural. Intradural arachnoid cysts usually arise posterior to the spinal cord in the thoracic spine region; however, these cysts very rarely develop in the cervical region. The pathogenesis of arachnoid cysts is unclear, although congenital, traumatic and inflammatory causes have been postulated. The authors believe that the formation of an arachnoid cyst cannot be explained by simply one mechanism because, in some reported cases, there has been accidental or iatrogenic trauma in association with congenital lesions. They also note that an intradural arachnoid cyst located anterior to the cervical spinal cord is an extremely rare disorder that may cause progressive myelopathy; however, the postoperative prognosis is good.- - - - - - - - - - ranking = 3keywords = trauma (Clic here for more details about this article) |
