1/112. Post-traumatic basilar artery thrombosis in a young man with atrial septum aneurysm and prothrombin gene G20210A polymorphism.prothrombin gene G20210A polymorphism has been recently identified as a cause of venous thrombosis. However the association between this mutation and arterial thrombosis remains uncertain. Some authors have suggested that the polymorphism in the 3' region of the prothrombin gene may precipitate cerebral arterial thrombosis in young patients with prothrombotic conditions. We report a case of post-traumatic basilar artery thrombosis in a young patient carrier of the prothrombin gene G20210A polymorphism. Thirty-six hours after sustaining a head injury in the occipital region, a young man developed vomiting, headache, dizziness and truncal ataxia, without signs of focal impairment. magnetic resonance imaging and selective angiography carried out 2 days later showed an obstruction of the basilar artery, with infarction of the right cerebellar region. A transthoracic echocardiogram showed a patent foramen ovale with little left-to-right shunt and an aneurysm of the interatrial septum. blood examination showed a heterozygous status for prothrombin gene G20210A polymorphism. We conclude that this prothrombin gene mutation and the coexisting particular head injury and interatrial septal aneurysm could have contributed simultaneously to the development of basilar artery occlusion and cerebellar infarction. We suggest that in selected cases of cerebellar ischemia a prothrombin gene G20210A polymorphism should be considered.- - - - - - - - - - ranking = 1keywords = headache (Clic here for more details about this article) |
2/112. Unilateral osseous bridging between the arches of atlas and axis after trauma.STUDY DESIGN: This is a case report. OBJECTIVE: To present a case of osseous bridging between C1 and C2 of posttraumatic origin and with an associated closed head injury and to discuss its pathogenesis and clinical outcome after surgical resection. SUMMARY OF BACKGROUND DATA: Heterotopic ossifications of posttraumatic origin in the spine are rare. To the authors' knowledge, no cases have been reported of spontaneous bony bridging between C1 and C2 with a posttraumatic origin. methods: Heterotopic ossifications were detected when pain and limited axial rotation (left/right 10 degrees/0 degree/20 degrees) were persistent, despite intensive physical therapy. Because heterotopic ossifications were ankylosing C1 and C2, the decision was to resect the osseous bridge in combination with a careful mobilization of the cervical spine. Functional computed tomography was performed for analysis of the postoperative results. RESULTS: Four months after surgery, clinical examination showed asymptomatic increased axial rotation. Functional computed tomography indicated that left C1-C2 axial rotation was reduced, possibly related to impingement caused by residual bony spurs. Pathologic changes in the surrounding soft tissue may be another important factor in the persistent limitation of rotation. CONCLUSIONS: Osseous bridging between C1 and C2 may be considered when persistent pain and limited axial rotation are observed after trauma. Operative resection, together with careful intraoperative and postoperative mobilization, may be the treatment of choice.- - - - - - - - - - ranking = 0.017711273767484keywords = pain (Clic here for more details about this article) |
3/112. Horner'sy syndrome and its significance in the management of head and neck trauma.The history, mechanism and aetiology of Horner'sy syndrome is presented and the pharmacology of the pupil is discussed. The case reported is a rare combination of Horner's syndrome in a patient who sustained bilateral fractures of the mandible and a chest injury. It is emphasised that the miotic changes in Horner's syndrome, in combination with head injuries can lead to confusion in diagnosis and the potential anaesthetic hazards and their influence on the management of the facial injury are outlined.- - - - - - - - - - ranking = 0.0071387587147499keywords = chest (Clic here for more details about this article) |
4/112. Reconstruction of the upper portion of the ear by using an ascending helix free flap from the opposite ear.Reconstruction of partial, marginal defects of the ear has been a challenge. The ascending helix free flap based on superficial temporal vessels has been described and used solely to repair nose defects. We used reversed pedicle helical free flap for the repair of a major loss of the upper one-third of the opposite auricle. The method permits the transfer of tissue of the same quality with satisfactory cosmetic result. The equalization of the ears in dimension was accomplished with minimal donor-site deformity.- - - - - - - - - - ranking = 0.019994559737062keywords = upper (Clic here for more details about this article) |
5/112. Roller coaster migraine: an underreported injury?A 28-year-old woman presented with severe headache, sleep problems, memory problems, and irritability 2 months after a violent roller coaster ride. She was diagnosed with posttraumatic migraine, and intravenous dihydroergotamine resolved her symptoms. Imaging studies, electroencephalogram, and visual and auditory evoked responses were normal. imipramine, divalproex sodium, and propranolol were prescribed to prevent the headaches from recurring and dihydroergotamine nasal spray was prescribed for breakthrough headaches. We consider the many short but significant brain insults delivered during the roller coaster ride a critical factor in triggering this instance of posttraumatic migraine, which while unmanaged was a source of significant disability for the patient.- - - - - - - - - - ranking = 3keywords = headache (Clic here for more details about this article) |
6/112. John Graham Senior Clinicians Award Lecture. Posttraumatic migraine.The term posttraumatic migraine has been used in several contexts. The purpose of this discussion is to outline the different circumstances in which migraine may follow trauma. Cases from the literature and from the headache Unit of Montefiore Medical Center are reviewed. Although trauma may be one of many triggers of migraine, trauma is sometimes the sole or predominant precipitating factor; e.g., footballer's migraine. In the posttraumatic syndrome, some exacerbations of headache upon a background of chronic daily headache often fulfill the criteria of migraine. Trauma may trigger the first attack of migraine in a susceptible individual. Biochemical and epidemiologic studies suggest that trauma may be the main etiologic factor of migraine in some cases. Migraine may also follow trauma on the basis of chance. Differentiating the different types of posttraumatic migraine has diagnostic, therapeutic, and legal implications.- - - - - - - - - - ranking = 2keywords = headache (Clic here for more details about this article) |
7/112. central nervous system superficial siderosis, headache, and epilepsy.Almost 95 cases of superficial siderosis of the central nervous system have been reported in the literature. These patients showed a clinical syndrome characterized by ataxia, deafness, pyramidal system involvement, and mental deterioration with xanthochromic cerebrospinal fluid and neuroradiological findings of hemosiderin deposits. About 30% of the patients had headache as an accompanying symptom. In the present case report, we describe a 33-year-old man with the typical clinical features of superficial siderosis, who complained, since aged 8, of a severe recurrent frontal headache often associated with loss of consciousness occurring after at least 2 hours of pain. The MRI and CSF findings were consistent with subarachnoid bleeding. In our patient, headache due to meningeal irritation by subarachnoid blood induced seizures as a probable reflex of extreme pain. carbamazepine and nimodipine prophylaxis dramatically reduced the frequency of headaches and seizures.- - - - - - - - - - ranking = 8.0177112737675keywords = headache, pain (Clic here for more details about this article) |
8/112. The injured coach.The patient in this case was diagnosed as having an epidural hematoma (shown in x-ray at right). This results from hemorrhage between the dura mater and the skull. The hemorrhage may result from a traumatic insult to the side of the head, which can fracture the temporal bone and lacerate the middle meningeal artery. Since the hemorrhage is arterial in nature, the patient may deteriorate quickly. These patients may present with what is referred to as a "lucid interval." The patient typically has a significant blow to the head that results in a short period of unconsciousness. They then regain consciousness at a time that frequently coincides with the arrival of EMS. Once conscious, they are in a period known as the lucid interval. They will still have a headache, but may otherwise be acting normally and show no other physical findings on examination. Many such patients refuse treatment and transport. [table: see text] Inside the skull, however, the problem will grow. Broken arterial vessels are bleeding, causing an expanding hematoma. The patient typically will soon complain of a severe headache along with other associated complaints, such as nausea/vomiting, then will lose consciousness again and/or have a seizure. Initial physical findings may include contralateral weakness and a decreased Glasgow coma score. As the hematoma expands, cerebral herniation may occur, compressing the third cranial nerve, which presents as a "blown pupil." EMS providers should have a high suspicion of injuries that affect the side of the head and the base of the skull. It is important to not only assess such injuries, but also the mechanism of injury, and to know the complications or later presentation that can arise from such injuries. Given that this patient was alert, oriented, not obviously intoxicated, and accompanied by his wife, the providers in this case would have had no choice but to abide by a refusal of treatment and transport. However, that could lead to serious complications, such as ongoing minor neurological deficits, later on. If this is the case, contacting medical control should be the priority.- - - - - - - - - - ranking = 2keywords = headache (Clic here for more details about this article) |
9/112. Transarterial intravenous coil embolization of dural arteriovenous fistula involving the superior sagittal sinus.BACKGROUND: We report a rare case of traumatic dural arteriovenous fistula involving the superior sagittal sinus successfully treated by transarterial intravenous coil embolization. CASE PRESENTATION: A 38-year-old woman presented with tension headache. She had a past history of severe head injury at the age of three. Computed tomography scanning showed a heterogenous low-density area in the right frontal lobe, and magnetic resonance imaging demonstrated abnormal vascular structures in the same area. angiography revealed a dural arteriovenous fistula involving the lateral wall of the fully patent superior sagittal sinus. The fistula was fed by scalp, meningeal, and cortical arteries, and drained into a cortical vein leading to the superior sagittal sinus. Femoral transarterial intravenous embolization with microcoils completely occluded the dural arteriovenous fistula. CONCLUSION: Severe head injury may lead to asymptomatic dural arteriovenous fistulas after a long time. Transarterial intravenous coil embolization can be effective in the treatment of dural arteriovenous fistulas involving the superior sagittal sinus.- - - - - - - - - - ranking = 1keywords = headache (Clic here for more details about this article) |
10/112. Periodic lateralized epileptiform discharges associated with subdural hematoma.A case presenting with headaches, organic dysfunction with visual hallucinations, and incontinence of urine, all of two days' duration is described here. EEG obtained on the fourth hospital day showed right-sided PLEDS and on the fifth hospital day a generalized seizure occurred. The other clinical and laboratory data led to a diagnosis of bilateral subdural hematomas. The patient recovered following surgical treatment. No etiologic factor other than the subdural hematomas was found to explain the PLEDS. Possible mechanisms of pathophysiology are discussed.- - - - - - - - - - ranking = 1keywords = headache (Clic here for more details about this article) |
