1/100. Carotid ligation for carotid aneurysms.Thirty patients with subarachnoid haemorrhage due to rupture of a carotid aneurysm were treated by ligation of the common carotid artery. Two patients died as a result of the procedure, two patients developed persisting hemisphere deficit. Eight of the ten patients who developed cerebral ischemia after the operation were operated within ten days after the bleeding. At present out aim is to guide the patient safely through the first ten days after his haemorrhage and perform ligation at the end of the second week. After a follow up period of 1-8 years recurrent haemorrhage did not occur. Common carotid ligation, preferably with control of carotid artery end pressure, cerebral blood-flow and EEG is considered to be a valuable method to treat ruptured intracranial carotid aneurysm.- - - - - - - - - - ranking = 1keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
2/100. Fusiform vertebral artery aneurysms as a cause of dissecting aneurysms. Report of two autopsy cases and a review of the literature.Two autopsy cases of angiographically determined fusiform aneurysms of the vertebral arteries (VAs) are reported and the appropriate literature is reviewed to investigate the pathological characteristics of both fusiform and dissecting VA aneurysms and the pathogenesis of dissecting aneurysms. One patient had suffered a subarachnoid hemorrhage (SAH) due to dissection of a previously documented incidental fusiform aneurysm. The other patient had harbored incidental fusiform aneurysms coexistent with a ruptured aneurysm of the posterior inferior cerebellar artery. The location and pathological features of the aneurysms were similar in the two cases. The aneurysms in both cases displayed intimal thickening, disruption of the internal elastic lamina, and degeneration of the media. A mural hemorrhage and patchy calcification were also found in the case that included SAH. Based on their pathological investigation of these two cases and a review of reported cases, the authors propose that incidental fusiform aneurysms in the VAs are characterized by weakness in the internal elastic lamina and, therefore, have the potential to become dissecting aneurysms, resulting in a fatal prognosis. This suggests that long-term control of blood pressure is mandatory in patients with incidental fusiform aneurysms in the VAs.- - - - - - - - - - ranking = 0.11327120126471keywords = subarachnoid (Clic here for more details about this article) |
3/100. systemic vasculitis and aneurysm formation in the wiskott-aldrich syndrome.A 24 year old male who suffered from the wiskott-aldrich syndrome developed intra-abdominal bleeding on two occasions. Radiological investigations showed aneurysmal dilatation of branches of the hepatic and superior mesenteric arteries. The second abdominal bleed necessitated laparotomy and the bleeding was localised to the kidneys. Right nephrectomy was performed and histological examination showed a necrotising vasculitis, mainly involving medium and small sized renal blood vessels. steroids, immunosuppressive treatment, and control of blood pressure resulted in resolution of the vasculitic process and prevented further haemorrhage. Vasculitis and aneurysm formation are rarely described complications of wiskott-aldrich syndrome and may account for the life threatening haemorrhage which occurs in this condition.- - - - - - - - - - ranking = 0.19216466617225keywords = haemorrhage (Clic here for more details about this article) |

5/100. Cavernous haemangioma of the retina and optic disc. A report of three cases and a review of the literature.We report characteristics of three cases of cavernous haemangioma of the retina, bringing to 37 the number now reported in the available literature. This rare, benign, congenital malformation is non-progressive, usually unilateral, somewhat more frequent in women, and rarely a source of intraocular haemorrhage. The fluorescein angiographic features include a normal arterial and venous supply, extraordinarily slowed venous drainage, no arterio-venous shunting, no disturbances of vascular permeability, and no secondary retinal exudation. Almost always, isolated clusters of vascular globules with plasma/erythrocyte sedimentation surround the main body of the malformation. These findings differentiate the anomaly from other retinal vascular diseases. Therapeutic intervention is seldom necessary.- - - - - - - - - - ranking = 0.096082333086126keywords = haemorrhage (Clic here for more details about this article) |
6/100. wiskott-aldrich syndrome: life-threatening haemorrhage from aneurysms within the liver, small bowel mesentery and kidney, requiring both surgical and radiological intervention.wiskott-aldrich syndrome (WAS) is a rare, generally X-linked recessive condition, originally described by Wiskott in 1937 as a triad of discharging ears, eczema and thrombocytopoenia. Aldrich included bloody diarrhoea in his report of 1954, with severe immunodeficiency and predisposition to malignancy being recognised subsequently. The incidence currently quoted is approximately 4 per million live male births, although there is some regional variation. We report the case of a long-term survivor who had massive haemorrhage from an intrahepatic aneurysm and, on a separate occasion, the right kidney.- - - - - - - - - - ranking = 0.48041166543063keywords = haemorrhage (Clic here for more details about this article) |
7/100. Surgical repair of clinoidal segment carotid artery aneurysms unsuitable for endovascular treatment.OBJECTIVE: Clinoidal segment carotid artery aneurysms are surgically challenging lesions. The aneurysm neck originates proximal to the distal dural ring, and the aneurysms typically are larger. Therefore, endovascular techniques are often considered to be the primary treatment option. Treatment techniques and results for 40 clinoidal segment carotid artery aneurysms that were considered unsuitable for contemporary endovascular intervention are analyzed in this report. methods: Forty aneurysms in 33 female and 3 male patients were treated surgically. Fifteen patients had bilateral aneurysms; of these patients, four underwent bilateral craniotomies. Twenty-seven aneurysms were 10 to 14 mm in size, eight were 15 to 24 mm, and five were more than 25 mm. The most common presentation was visual loss, which occurred in 13 patients. Seven patients presented with subarachnoid hemorrhage. RESULTS: Thirty-seven aneurysms were directly repaired with clipping, two were trapped with bypass, and one was trapped without bypass. The complication rate was 10%, with one major stroke, two minor strokes, and one successfully treated brain abscess. CONCLUSION: Surgical treatment of clinoidal segment carotid artery aneurysms can produce acceptable outcomes. Specific preoperative and intraoperative techniques facilitate improved surgical results for aneurysms that are not treatable with contemporary endovascular techniques.- - - - - - - - - - ranking = 0.11327120126471keywords = subarachnoid (Clic here for more details about this article) |
8/100. Aneurysms of the lateral spinal artery: report of two cases.OBJECTIVE AND IMPORTANCE: The goal of this report was to describe aneurysms arising from the lateral spinal artery. The locations of aneurysms contributing to subarachnoid hemorrhage (SAH) have been well characterized and are primarily in the circle of willis or at the bifurcation points of the internal carotid artery or the vertebrobasilar system. Although the spinal arteries are also in direct communication with the subarachnoid space, aneurysms of these arteries that lead to SAH are rare. To date, only aneurysms of the anterior and posterior spinal arteries have been described. In this communication, we report two patients with aneurysms of the lateral spinal artery who presented with SAH. CLINICAL PRESENTATION: review of our neurointerventional database from 1997 to the present revealed two patients with lateral spinal artery aneurysms. The medical records, as well as the operative and radiological findings, were reviewed for both patients. In both cases, the lateral spinal arteries were involved as collateral pathways for occlusive vertebral lesions, suggesting hemodynamic stress as a cause. INTERVENTION: Endovascular treatment was attempted in both cases and was successful in one; open surgery, with aneurysm resection, was performed in the other case. We review the vascular anatomic features of the spinal cord as they relate to the lateral spinal artery, as well as treatment options for lateral spinal artery aneurysms. CONCLUSION: Lateral spinal artery aneurysms are a rare cause of SAH. Both endovascular and surgical treatment options are available.- - - - - - - - - - ranking = 0.22654240252943keywords = subarachnoid (Clic here for more details about this article) |
9/100. Bilateral vertebral artery balloon occlusion for giant vertebrobasilar aneurysms.We describe the clinical presentation, radiological and clinical results in six consecutive patients with a giant vertebrobasilar aneurysm treated by bilateral vertebral artery balloon occlusion. Five patients presented with headache and signs of brain-stem compression and one with subarachnoid haemorrhage. In all patients vertebral artery balloon occlusion was performed. In four, this followed successful test occlusion. In one patient, who did not tolerate the test occlusion, a bypass from the external carotid to the posterior cerebral artery preceded definitive vertebral artery occlusion. One patient underwent bypass surgery prior to test occlusion. At 6-22 months follow-up three patients had a good functional outcome and showed unchanged size or shrinkage of the aneurysm on MRI. Three other patients died; one from recurrent haemorrhage, and two probably from delayed brain-stem ischaemia. The presence of two large posterior communicating arteries predicted good functional outcome, which was also related to the clinical condition at presentation, and the degree of brain-stem compression and oedema on MRI. Bilateral vertebral artery balloon occlusion can be considered in patients with otherwise untreatable giant vertebrobasilar aneurysms. If test occlusion is not tolerated, a surgical bypass to the posterior circulation can be considered.- - - - - - - - - - ranking = 0.90391766691387keywords = subarachnoid haemorrhage, subarachnoid, haemorrhage (Clic here for more details about this article) |
10/100. Transluminal stent-assisted coil embolization of a vertebral confluence aneurysm: technique report.BACKGROUND: Recent advances in stent technology have allowed for negotiation of often tortuous posterior circulation intracranial vasculature. Stent-assisted coil embolization is a novel treatment for complex wide-necked aneurysms, as stents provide a buttress that allows for coil deposition while preventing coil herniation into the parent vessel lumen. We describe a case of stent-assisted coil embolization of a complex wide-necked vertebral confluence aneurysm. CASE DESCRIPTION: A 61-year-old woman presented with a Hunt-Hess III, Fisher Grade III subarachnoid hemorrhage secondary to a ruptured vertebral confluence aneurysm demonstrated on angiography. The patient underwent emergent angiography and attempted coiling of a vertebral confluence aneurysm. Because of the aneurysm's complex wide neck and the presence of subclavian steal syndrome, the coils repeatedly herniated into the left vertebral and basilar artery lumina. A flexible coronary stent was deployed across the aneurysm neck, preventing coil herniation and allowing for greater coil deposition. The patient tolerated the procedure and underwent repeat coiling 2 months postoperatively because of mild coil compaction. This resulted in 100% occlusion and the patient is neurologically normal except for a sixth nerve palsy which had been present after the hemorrhage. CONCLUSION: Recent advances in stent technology allow negotiation of the tortuous posterior circulation vasculature. Stent-assisted coil embolization of complex, wide-necked vertebral confluence aneurysms may be an alternative intervention for these surgically challenging lesions.- - - - - - - - - - ranking = 0.11327120126471keywords = subarachnoid (Clic here for more details about this article) |
