1/79. Intraventricular hemorrhage as a false localizing sign of a thoracolumbar arteriovenous malformation: case report.BACKGROUND: Spinal arteriovenous malformation (SAVM) is a relatively rare disease characterized by a high incidence of intramedullary and subarachnoid haemorrhage. When the hemorrhage is profuse and the SAVM is in the cervical region the symptoms (disturbance of consciousness, papilledema, cranial nerve palsies, and convulsions) may be so severe and rapid in their onset that they may be mistaken for intracranial hemorrhage. We report here on a patient with a SAVM at T10-12, which bled intracranially, mainly intraventricularly, and resulted first in respiratory arrest and unconsciousness. CASE DESCRIPTION: The patient had been well until he was 28 years old when, during intercourse, he suffered a terrible headache and suddenly lost consciousness, with a transient respiratory arrest. He was also noted to have right hemiparesis. A computed tomography scan demonstrated intraventricular hemorrhage. After a 24-hour period of artificial ventilation the patient regained consciousness and the right arm paresis completely recovered, but a gradual worsening of the motor function of the left leg developed. Digital subtraction angiography did not demonstrate any intracranial source of bleeding, whereas spinal angiography revealed a SAVM located at the medullary cone, which was totally removed by surgery. CONCLUSION: The case reported here raises several important issues. First, the advisability of spinal magnetic resonance imaging in the investigation of intraventricular (and subarachnoid) hemorrhage in patients with no demonstrable intracranial source. Secondly, the benefits of early diagnosis and reestablishment of the spinal cord circulation before the onset of thrombosis and the progressive phase of myelopathy. Finally, the necessity of complete obliteration and treatment of SAVMs even in patients with fixed neurologic deficits, because rebleeding of lower thoracic or lumbar SAVMs can lead to impairment at a higher level with severe or lethal consequences.- - - - - - - - - - ranking = 1keywords = subarachnoid haemorrhage, haemorrhage, subarachnoid (Clic here for more details about this article) |
2/79. 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 = 1.0117627850404keywords = haemorrhage (Clic here for more details about this article) |
3/79. Multiple cerebral arteriovenous malformations (AVMs) associated with spinal AVM.The co-existence of multiple cerebral arteriovenous malformations (AVMs) and a spinal AVM is extremely rare. A 22-year-old man suddenly developed severe headache. Computed tomography (CT) scan showed intracerebral haemorrhage in the left occipital lobe. cerebral angiography revealed eight AVMs; four were in the right frontal lobe and two each were in the right temporal and left occipital lobe, respectively. A huge high-flow spinal AVM was found incidentally. He had no other vascular lesions such as hereditary haemorrhagic telangiectasia. A left occipital craniotomy was performed and the ruptured left occipital AVMs were removed. Further therapeutic treatment was refused. To our knowledge, except for one autopsy case, this is the first reported patient with multiple cerebral AVMs with a spinal AVM. We discuss the characteristics of this case and review reported cases with cerebral and spinal AVMs.- - - - - - - - - - ranking = 0.25294069626011keywords = haemorrhage (Clic here for more details about this article) |
4/79. Fatal haemorrhage from Dieulafoy's disease of the bronchus.A 70 year old woman with a previous history of healed tuberculosis and suspected chronic obstructive pulmonary disease presented with recurrent haemoptysis and respiratory failure from a lobar pneumonia. Massive bleeding occurred when biopsy specimens were taken during bronchoscopy which was managed conservatively, but later there was a fatal rebleed from the same site. Two different Dieulafoy's vascular malformations were found in the bronchial tree at necropsy, one of which was the biopsied lesion in the left upper lobe. This report confirms the possibility that vascular lesions occur in the bronchial tree. It is suggested that, if such lesions are suspected at bronchoscopy, bronchial and pulmonary arteriography with possible embolotherapy should be performed.- - - - - - - - - - ranking = 1.0117627850404keywords = haemorrhage (Clic here for more details about this article) |
5/79. 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 = 0.25939283592437keywords = subarachnoid (Clic here for more details about this article) |
6/79. Arteriovenous shunting in a giant renal angiomyolipoma. A rare condition.We report a case of a 33-year-old woman with tuberous sclerosis and bilateral angiomyolipomas. She suffered from acute left flank pain due to retroperitoneal haemorrhage. During renal arteriography an arteriovenous shunting was found in the left tumour. angiomyolipoma is a rare cause of angiographically demonstrable arteriovenous shunting.- - - - - - - - - - ranking = 0.25294069626011keywords = haemorrhage (Clic here for more details about this article) |
7/79. Type IV spinal arteriovenous malformation in association with familial pulmonary vascular malformations: case report.OBJECTIVE AND IMPORTANCE: Type IVc arteriovenous malformations (AVMs) of the spinal cord consist of multiple high-flow feeding vessels, and they often present a challenging management situation. Their location is intradural and extramedullary, and they are rare malformations that are difficult to treat owing to the risk of thrombosis of the anterior spinal artery. The authors report a case of Type IVc spinal AVM in a patient with a family history of three siblings with pulmonary AVMs. Spinal AVMs have been reported to be associated with inherited syndromes such as familial cutaneous hemangiomas and Kartagener's syndrome, but an association with pulmonary AVMs has not previously been described. CLINICAL PRESENTATION: A 27-year-old man presented with sudden onset of occipital headache with cervical radiation while weightlifting. Results of computed tomography of the brain were normal, but lumbar puncture revealed a subarachnoid hemorrhage. The patient had a 1-year history of a neurogenic bladder and exhibited marked left calf muscle wasting. INTERVENTION: The patient underwent spinal magnetic resonance imaging, which revealed the AVM in the conus region. Selective spinal angiography was performed for diagnostic purposes. A laminectomy was performed, and the vessels feeding the AVM were clipped, as was the fistula. CONCLUSION: The patient remained neurologically stable, and angiography confirmed obliteration of the AVM. This is the first case report of a patient with a spinal AVM who had multiple siblings with pulmonary malformations or AVMs.- - - - - - - - - - ranking = 0.12969641796219keywords = subarachnoid (Clic here for more details about this article) |
8/79. Spontaneous occlusion of ruptured vertebral artery dissection at the extradural fenestration associated with extradural origin of the posterior inferior cerebellar artery--case report.A 69-year-old female suffered from sudden onset of severe headache. Computed tomography showed subarachnoid hemorrhage primarily located in the posterior fossa. Initial angiography demonstrated a fenestration of the vertebral artery and an extracranial origin of the posterior inferior cerebellar artery. However, no bleeding points could be clearly detected. The operative findings revealed a massive clot in subarachnoid space, but no bleeding point. Serial angiography demonstrated dissection in one of the limbs of the fenestrated vertebral artery on the 25th day after the onset. On the 100th day, the lesion was spontaneously occluded. The patient is presently doing well at 8 years after surgery.- - - - - - - - - - ranking = 0.25939283592437keywords = subarachnoid (Clic here for more details about this article) |
