1/15. Spontaneous resolution of bilateral traumatic carotid cavernous fistulas and development of trans-sellar intercarotid vascular communication: case report.BACKGROUND: Bilateral carotid cavernous fistulas may complicate head injury. Spontaneous resolution of post-traumatic direct carotid cavernous fistula is rare. CASE DESCRIPTION We present a case of a 42-year-old female who developed post-traumatic high flow bilateral carotid cavernous fistulas with cortical and deep venous drainage, who had a spontaneous resolution with thrombosis of the cavernous sinus outlets bilaterally and development of a trans-sellar intercarotid vascular communication. To our knowledge this is the first reported case in the literature describing such a phenomenon. CONCLUSION Bilateral direct carotid cavernous fistulas may undergo spontaneous resolution and form a benign trans-sellar intercarotid vascular communication.- - - - - - - - - - ranking = 1keywords = thrombosis (Clic here for more details about this article) |
2/15. Sigmoid sinus thrombosis after mild closed head injury in an infant: diagnosis by magnetic resonance imaging in the acute phase--case report.Intracranial sinus thrombosis following a mild closed head injury without a skull fracture or intracranial hematoma is extremely rare. A 23-month-old girl presented with vomiting and gait ataxia 1 day after occipital trauma. Computed tomography revealed a slightly increased density area in the region of the left sigmoid sinus. T1-weighted magnetic resonance (MR) imaging demonstrated an isointense area in the left sigmoid sinus and T2-weighted imaging showed a hyperintense area reflecting the characteristics of oxyhemoglobin. MR angiography and cerebral angiography indicated occlusion of the left sigmoid sinus. After 4 days of conservative treatment, her symptoms subsided completely. Follow-up MR angiography and cerebral angiography showed recanalization of the sigmoid sinus. The MR images and MR angiograms were useful for both early diagnosis and follow-up. Treatment should reflect the severity of individual cases, and early diagnosis will help achieve a good outcome.- - - - - - - - - - ranking = 5keywords = thrombosis (Clic here for more details about this article) |
3/15. Sigmoid and transverse sinus thrombosis after closed head injury presenting with unilateral hearing loss.Sinus thrombosis has rarely been associated with closed head injury; more often, thrombosis of the sigmoid or transverse sinus is caused by otogenic inflammations or tumours, or occurs during pregnancy. Symptoms are frequently vague, while untreated thrombus progression may be fatal due to venous congestion and infarction. We report a 32-year-old man presenting with right hearing loss, tinnitus and headache 2 days after a closed head injury. Neurological examination showed no additional abnormality. The EEG showed focal bifrontal slowing. CT revealed a fracture of the occipital bone. MRI and MRA demonstrated complete thrombosis of the right sigmoid and transverse sinuses. After 2 weeks of intravenous heparin therapy followed by warfarin, the patient's hearing improved and MRI and MRA showed complete recanalisation of the sigmoid and transverse sinuses. Venous sinus thrombosis can be an undetected sequel to head injury. Appropriate imaging studies should be carried out to enable therapy to be started as soon as possible.- - - - - - - - - - ranking = 8keywords = thrombosis (Clic here for more details about this article) |
4/15. Children with cerebral venous thrombosis diagnosed with magnetic resonance imaging and magnetic resonance angiography.From 1985 to 1991, 13 children were diagnosed at the University of illinois College of medicine at Peoria, Saint Francis Medical Center, with cerebral venous thrombosis (CVT) by magnetic resonance imaging scan. Ages ranged from newborn to 5 years. Six children were premature neonates, five were term neonates and two were 5 years old. In the premature neonates, thrombosis was usually associated with other problems. All the term neonates had seizures. In all neonates, thrombosis resolved without any specific treatment. In the two older children, one presented with pseudotumor cerebri and one with coma. These children required neurosurgical intervention. Follow-up magnetic resonance imaging scans were obtained in 9 of 13 children and showed thrombus resolution in each case. Three children were studied in the acute and convalescent stages by magnetic resonance angiography using time-of-flight techniques. Each follow-up magnetic resonance angiogram showed improvement in venous flow consistent with their clinical course and other imaging studies. We conclude that 1) CVT in children encompasses a range of clinical conditions which may or may not require neurosurgical intervention; 2) magnetic resonance imaging is superior to other modalities for the diagnosis of CVT; and 3) magnetic resonance angiography is an alternative means to monitor the evolution of CVT and efficacy of therapeutic intervention.- - - - - - - - - - ranking = 7keywords = thrombosis (Clic here for more details about this article) |
5/15. Uncommon cause of sinus thrombosis following closed mild head injury in a child.OBJECT: Sinus thrombosis following a closed mild head injury is rare. A case of dural sinus thrombosis following a mild closed head injury due to an uncommon cause is reported. methods: A 7-year-old child presented with GCS 15 after a road traffic accident. CT revealed an occipital fracture. Ten days later the child developed signs of increased intracranial pressure. An MR venogram at this time revealed thrombosis of the transverse sinus with hypoplasia of the contralateral transverse and sigmoid sinuses. The patient's anitiphospholipid antibody titres were elevated. The patient was treated with anticoagulants and improved. CONCLUSIONS: The role of inherited and acquired procoagulant factors in the aetiology of sinus thrombosis is increasingly being recognized. When a patient presents with sinus thrombosis after a closed mild head injury, it is necessary to investigate for the presence of risk factors for thrombophilia as it has implications for the long-term management of the patient.- - - - - - - - - - ranking = 9keywords = thrombosis (Clic here for more details about this article) |

7/15. Superior sagittal sinus thrombosis associated with raised intracranial pressure in closed head injury with depressed skull fracture.A case of delayed signs of intracranial hypertension following closed head injury with a depressed cranial fracture and superior sagittal sinus thrombosis is reported. Conservative treatment of intracranial hypertension, including just repeated lumbar puncture and oral acetazolamide, was performed. Spontaneous recanalization of the superior sagittal sinus was observed. Pathogenesis and different modalities of treatment are discussed.- - - - - - - - - - ranking = 5keywords = thrombosis (Clic here for more details about this article) |
8/15. Direct thrombosis of a pseudoaneurysm after obliteration of a carotid-cavernous fistula with cellulose acetate polymer: technical case report.A 55-year-old man who suffered a head injury resulting in a left traumatic carotid-cavernous fistula was successfully treated with an intravascular detachable balloon. A pseudoaneurysm formed adjacent to the balloon. Seven months after the initial procedure, treatment with cellulose acetate polymer, a new liquid thrombotic material, occluded the pseudoaneurysm and preserved the internal carotid artery.- - - - - - - - - - ranking = 4keywords = thrombosis (Clic here for more details about this article) |
9/15. Post-traumatic cerebral air embolism. Case report.A case of post-traumatic cerebral air embolism is presented. In the chest-X-radiography fractures of many ribs and hemo-pneumothorax were visible on the right side associated with intra-alveolar, interstitial hemorrhages and mediastinal emphysema. At the end of a CT scan of the head appeared features of arterial air embolism. The patient was diagnosed as brain dead and cardiac arrest occurred one hour after.- - - - - - - - - - ranking = 0.37874232202453keywords = embolism (Clic here for more details about this article) |
