11/1665. Subtemporal suboccipital transpetrosal transsigmoidal approach to aneurysm of the basilar artery fenestration.

    The aneurysm arising from the lower third of a basilar artery fenestration is a rare event. The traditional suboccipital or subtentorial transtentorial or transoral approach to this vascular malformation can be problematic. We report the case of a 52-year-old woman who suffered a Grade 4 subarachnoid hemorrhage from an aneurysm located at a fenestration of the proximal third of the basilar artery. This aneurysm was successfully clipped through a left subtemporal suboccipital translabyrinthine transsigmoidal approach. In the aneurysms of the proximal third of the basilar artery the transpetrosal approach with its variants (translabyrinthine and transsigmoidal) related to patient's clinical condition can be useful with undoubted advantages.

12/1665. Bedside-microdialysis for early detection of vasospasm after subarachnoid hemorrhage. Case report and review of the literature.

    Continuous monitoring of cerebral metabolism would be desirable for early detection of vasospasm in SAH patients. Bedside-microdialysis, a new technique for on-line monitoring of cerebral metabolism, may reflect changes seen in cerebral vasospasm diagnosed by transcranial Doppler sonography (TCD). This report represents the first case of combined TCD monitoring and on-line microdialysis from the brain extracellular fluid in a SAH patient. A 48-year-old woman suffered subarachnoid hemorrhage grade IV according to Hunt and Hess. Angiography revealed an aneurysm of the left carotid artery. The aneurysm was clipped 45 hours after bleeding. The microdialysis catheter was inserted after aneurysm clipping into the white matter of the left temporal lobe. Sampling of microdialysates started immediately, analyzing time for glucose, lactate, pyruvate and glutamate was four minutes. Postoperatively, the patient was doing well and microdialysis and TCD parameters remained within normal range. On the third postoperative day a shift to anaerob metabolism (decrease of glucose, increase of lactate and the lactate-pyruvate ratio up to pathological levels) and an increase in glutamate was observed suggesting insufficient cerebral perfusion. The patient progressively deteriorated clinically. Vasospasm was diagnosed by TCD monitoring 36 hours after onset of ischemic changes monitored by microdialysis. After elevation of mean arterial blood pressure, TCD values and metabolic parameters normalized. Interestingly, the pathological changes in on-line microdialysis preceded the typical increase in blood flow velocity by TCD and the clinical deterioration. Our case suggests, that bedside-microdialysis may be useful for early detection of vasospasm and continuous surveillance of treatment and may be a new guide to treat ischemic neurological deficits following SAH.

13/1665. 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. ( info)

14/1665. Endovascular treatment of multiple aneurysms involving the posterior intracranial circulation.

    The results of surgery on multiple intracranial aneurysms tha involve the vertebrobasilar circulation are poor, and associated patient mortality remains high. We describe the endovascular treatment of four patients with mutiple aneurysms that involved the posterior intracrancial circulation. Satisfactory occlusion of all aneurysms was achieved by using electrolytically detachable coils, and all patients had a good clinical recovery. Our early experience suggests that endovascular coil occlusion may be a particularly suitable method for treating this high-risk condition. ( info)

15/1665. 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. ( info)

16/1665. 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. ( info)

17/1665. Intraoperative use of nitric oxide during intracranial aneurysm clipping in a patient with acute respiratory distress syndrome.

    We describe a case of subarachnoid hemorrhage (SAH) complicated by acute respiratory distress syndrome (ARDS) and cerebral vasospasm. Inhaled nitric oxide (NO) was used to improve oxygenation, thereby facilitating cerebral aneurysm clipping. ( info)

18/1665. Resolution of third nerve paresis after endovascular management of aneurysms of the posterior communicating artery.

    The effect of endovascular treatment on the recovery of neural function in patients with third nerve palsy caused by an aneurysm of the posterior communicating artery is poorly documented. We report three cases in which third nerve paresis resolved completely within 2 to 3 weeks of endovascular occlusion of a posterior communicating artery aneurysm. ( info)

19/1665. Contrast agent neurotoxicity presenting as subarachnoid hemorrhage.

    A patient developed signs, symptoms, and radiologic findings compatible with acute subarachnoid hemorrhage after receiving a large dose of heparin and intravascular contrast medium for coronary angiography and stent placement. Subsequent CT indicated the subarachnoid enhancement was due to contrast. Neurotoxicity from contrast agents is well-known, however this is an unusual report of toxicity mimicking subarachnoid hemorrhage clinically and radiologically. ( info)

20/1665. 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. ( info)
