1/212. Dural arteriovenous fistula of the cervical spine presenting with subarachnoid hemorrhage.We describe a case of dural arteriovenous fistula (DAVF) presenting with subarachnoid hemorrhage (SAH). The diagnosis of DAVF was based on spinal angiography. A review of the literature revealed that five of 13 previously reported DAVFs of the cervical spine were accompanied by SAH. SAH has not been observed in DAVFs involving other segments of the spinal canal.- - - - - - - - - - ranking = 1keywords = spinal, spinal canal, canal (Clic here for more details about this article) |
2/212. Spinal subarachnoid hemorrhage attributable to schwannoma of the cauda equina.BACKGROUND: cauda equina syndrome occurring as a result of spontaneous spinal subarachnoid hemorrhage (SAH) from a spinal tumor is reported to be rare. CASE DESCRIPTION: A 28-year-old woman presented at our clinic with a history of severe back pain for 10 days, progressive paraparesis, and urinary retention. Her physical examination revealed a mass located intradurally at the level of L1-2 and a massive SAH. An L1-L2, laminectomy and a hemilaminectomy from D9 to D12 were performed and the SAH was evacuated and the cord was decompressed. CONCLUSION: At the first year follow-up, her restricted dorsal and plantar flexion continued. Post-gadolinium magnetic resonance imaging revealed no mass.- - - - - - - - - - ranking = 0.83510842707503keywords = spinal (Clic here for more details about this article) |
3/212. subarachnoid hemorrhage due to septic embolic infarction in infective endocarditis.During antibiotic therapy, a 56-year-old man with a streptococcus bovis endocarditis developed an infarction of the right middle cerebral artery (MCA). Thirty hours after stroke onset, cranial computed tomography controls demonstrated a secondary subarachnoid hemorrhage, marked in the cistern of the right MCA. The latent period, cerebrospinal fluid analysis, angiographic and pathologic findings favor the assumption of a pyogenic arterial wall necrosis of the MCA due to a septic embolus. This pathomechanism of intracranial hemorrhage in infective endocarditis should be distinguished from a rupture of a mycotic aneurysm.- - - - - - - - - - ranking = 0.41755421353752keywords = spinal (Clic here for more details about this article) |
4/212. Anaesthetic management of a woman who became paraplegic at 22 weeks' gestation after a spontaneous spinal cord haemorrhage secondary to a presumed arteriovenous malformation.A 19-yr-old woman developed a paraplegia with a T10 sensory level at 22 weeks' gestation. The spinal injury was caused by spontaneous bleed of a presumed arteriovenous malformation in the spinal cord. She presented for Caesarean section at term because of the breech position of her fetus. The successful use of a combined spinal epidural-regional anaesthetic is described and the risks of general and regional anaesthesia are discussed.- - - - - - - - - - ranking = 2.9228794947626keywords = spinal (Clic here for more details about this article) |
5/212. spinal cord arteriovenous malformations in two patients with hereditary hemorrhagic telangiectasia.We report two cases, in first cousins, of spinal arteriovenous malformations (AVMs) of the perimedullary fistula type and hereditary hemorrhagic telangiectasia (HHT). Spinal AVMs are a rare clinical presentation of HHT, but can be the first manifestation in a child with this disorder. The importance of considering a coexisting disorder of vascular dysplasia, such as HHT, when a child presents with a spinal AVM is discussed.- - - - - - - - - - ranking = 0.83510842707503keywords = spinal (Clic here for more details about this article) |
6/212. Recanalization and rupture of a giant vertebral artery aneurysm after hunterian ligation: case report.OBJECTIVE AND IMPORTANCE: Recanalization and subsequent rupture of giant aneurysms of the posterior circulation after Hunterian ligation is an extremely rare event that has been noted to occur with basilar apex, basilar trunk, and vertebrobasilar junction aneurysms. We report the case of a giant, previously unruptured right vertebral artery aneurysm, which recanalized from the contralateral vertebral artery and subsequently ruptured after previously performed angiography showed complete thrombosis of the aneurysm. CLINICAL PRESENTATION: A 72-year-old woman presented with headaches, ataxia, and lower extremity weakness. A giant 3-cm right vertebral artery aneurysm was found during the patient evaluation. INTERVENTION: Because of the size of the aneurysm and the absence of a discrete neck, Hunterian ligation was performed. After treatment, angiograms showed no filling of the aneurysm from either the right or left vertebral artery. Nine days later, after the patient developed lethargy and nausea, repeat angiography showed that a small portion of the aneurysmal base had recanalized. The next day, the patient had a massive subarachnoid hemorrhage and subsequently died. CONCLUSION: We think that this is a previously undescribed complication associated with direct arterial ligation of giant vertebral artery aneurysms. patients with aneurysms treated using Hunterian ligation need to be followed up closely. Even aneurysms that have minimal recanalization are at risk for subarachnoid hemorrhage.- - - - - - - - - - ranking = 0.022281761057546keywords = canal (Clic here for more details about this article) |
7/212. rupture of a cervical spinal cord arteriovenous malformation: a rare complication of endovascular embolization.patients suffering from a cervical spinal cord arteriovenous malformation (SCAVM) run high risk of devastating subarachnoid hemorrhage and hematomyelia. Therefore, cervical SCAVMs represent a compelling indication for surgical or endovascular therapy. The authors report on an acute life-threatening subarachnoid hemorrhage from a cervical SCAVM that ruptured during an embolization procedure. causality and therapeutic management are discussed.- - - - - - - - - - ranking = 2.0877710676876keywords = spinal (Clic here for more details about this article) |
8/212. Ruptured anterior spinal artery aneurysm: a case report.BACKGROUND: Spinal artery aneurysms are rare, and are usually found in association with arteriovenous malformations or coarctation of the aorta. CASE REPORT: A 42-year-old man with a ruptured anterior spinal artery aneurysm is presented here. He experienced subarachnoid hemorrhage, which was confirmed by computed tomography. magnetic resonance imaging revealed an aneurysm in front of the upper part of the medulla. angiography demonstrated bilateral vertebral artery occlusion. Distal vertebral arteries and the basilar artery were perfused via the dilated anterior spinal artery, which originates in the right subclavian artery. The aneurysm was located at the distal part of the anterior spinal artery, and was successfully clipped through a lateral suboccipital craniotomy 2 months after bleeding from the aneurysm. After rehabilitation, the patient was able to walk with no apparent neurologic deficit. CONCLUSIONS: This case suggests that the anterior spinal artery as a collateral route after bilateral vertebral artery occlusion is under hemodynamic stress, resulting in aneurysm formation and rupture.- - - - - - - - - - ranking = 3.3404337083001keywords = spinal (Clic here for more details about this article) |
9/212. moyamoya disease of adult onset brain stem haemorrhage associated with bilateral occlusion of the vertebral arteries--case report.An unusual and first case of moyamoya disease of adult onset brain stem haemorrhage associated with occlusion of both vertebral arteries is reported. A 30-year-old man suddenly suffered from dyspnea, dysphagia, and left-sided hemisensory disturbance. Computed tomography and magnetic resonance imaging revealed a fresh haematoma in the left medulla oblongata and various-sized old infarcts in both parietal lobes. Cerebral angiograms disclosed occlusion of the bilateral internal carotid arteries on both sides at their intracranial portion, accompanied with the developed basal moyamoya vessels. The right vertebral artery occluded at its V2-V3 segment, in which the posterior inferior cerebellar artery was opacified via the posterior spinal artery, and the basilar artery was filled from the anterior spinal artery. The left vertebral artery was also occluded at the craniovertebral junction (V4) with collateral flow. Only one case of moyamoya disease associated with bilateral occlusion of the vertebral artery has been reported previously, and a haemorrhage into the medulla oblongata in moyamoya disease has never been described.- - - - - - - - - - ranking = 0.83510842707503keywords = spinal (Clic here for more details about this article) |
10/212. Nontraumatic acute spinal subdural hematoma: report of five cases and review of the literature.Acute subdural spinal hematoma occurs rarely; however, when it does occur, it may have disastrous consequences. The authors assessed the outcome of surgery for this lesion in relation to causative factors and diagnostic imaging (computerized tomography [CT], CT myelography), as well as eventual preservation of the subarachnoid space. The authors reviewed 106 cases of nontraumatic acute subdural spinal hematoma (101 published cases and five of their own) in terms of cause, diagnosis, treatment, and long-term outcome. Fifty-one patients (49%) were men and 55 (51%) were women. In 70% of patients the spinal segment involved was in the lumbar or thoracolumbar spine. In 57 cases (54%) there was a defect in the hemostatic mechanism. spinal puncture was performed in 50 patients (47%). Late surgical treatment was performed in 59 cases (56%): outcome was good in 25 cases (42%) (in 20 of these patients preoperative neurological evaluation had shown mild deficits or paraparesis, and three patients had presented with subarachnoid hemorrhage [SAH]). The outcome was poor in 34 cases (58%; 23 patients with paraplegia and 11 with SAH). The formation of nontraumatic acute spinal subdural hematomas may result from coagulation abnormalities and iatrogenic causes such as spinal puncture. Their effect on the spinal cord and/or nerve roots may be limited to a mere compressive mechanism when the subarachnoid space is preserved and the hematoma is confined between the dura and the arachnoid. It seems likely that the theory regarding the opening of the dural compartment, verified at the cerebral level, is applicable to the spinal level too. Early surgical treatment is always indicated when the patient's neurological status progressively deteriorates. The best results can be obtained in patients who do not experience SAH. In a few selected patients in whom neurological impairment is minimal, conservative treatment is possible.- - - - - - - - - - ranking = 4.5930963489127keywords = spinal (Clic here for more details about this article) |
