1/1602. Radical surgery of a giant Galen's vein aneurysm using total circulatory arrest: case report.BACKGROUND: arteriovenous malformations of Galen's vein are a rare type of vascular anomaly. The complex anatomy of these lesions creates an extremely difficult management dilemma. We report successful surgical treatment of a 7-year-old patient with a Galen's vein aneurysm. methods AND RESULTS: A 7-year-old patient with slowly progressing gait disturbance, emotional instability, and strange behaviour is presented. A computed tomography scan revealed a high-density mass in the pineal region and cerebral angiography showed an aneurysm of Galen's vein. We decided to perform surgical excision of the aneurysm. The operation was performed under hypothermic circulatory arrest with barbiturate cerebral protection. The patient had no signs of postoperative ischemic deficits, hemorrhage, or neurologic deterioration. CONCLUSIONS: Various techniques have been described for the obliteration of Galen's vein aneurysms, including direct surgical approach, staged operation, and transarterial, transvenous or transtorcular embolization. We present this patient to illustrate the use of hypothermic circulatory arrest and barbiturate cerebral protection for successful surgical excision of this complex vascular lesion. The combination of these techniques allowed us, in this case, to operate with reasonable safety on otherwise, difficult to treat aneurysm of Galen's vein.- - - - - - - - - - ranking = 1keywords = cerebral (Clic here for more details about this article) |
2/1602. Giant fusiform aneurysm of the middle cerebral artery: successful Hunterian ligation without distal bypass.Giant fusiform aneurysm is a rare vascular lesion which presents difficult management issues. We describe one such aneurysm in a middle cerebral artery branch (M2) that presented with subarachnoid haemorrhage and was managed operatively. Clinical, radiological and pathological presentations, as well as the different treatment options for this type of aneurysm are discussed based on a literature review. A satisfactory results in an M2 giant fusiform aneurysm can be achieved with Hunterian ligation of the parent vessel even when a distal EC-IC bypass is not possible.- - - - - - - - - - ranking = 1.996135884371keywords = cerebral, haemorrhage (Clic here for more details about this article) |
3/1602. Intra-arterial infusion of fasudil hydrochloride for treating vasospasm following subarachnoid haemorrhage.In this pilot study we treated cerebral vasospasm in patients with subarachnoid haemorrhage to assess intra-arterial fasudil hydrochloride. We analysed effects of intra-arterial infusion on angiographically evident cerebral vasospasm in 10 patients including 3 with symptoms of vasospasm. Over 10 to 30 min 15 to 60 mg was administered via the proximal internal carotid artery or vertebral artery following standard angiography, without superselective techniques. A total of 24 arterial territories (21 internal carotid, 3 vertebral) were treated. Angiographic improvement of vasospasm was demonstrated in 16 arterial territories (local dilation in 2, diffuse dilation in 14) in 9 patients. In 2 symptomatic patients, intra-arterial fasudil hydrochloride was associated with resolution of symptoms without sequelae. In the third symptomatic patient the benefit of fasudil hydrochloride was only temporary, and a large cerebral infarction occurred. All asymptomatic patients showed no progression of angiographic to symptomatic vasospasm after treatment with intra-arterial fasudil hydrochloride. No adverse effect was encountered.- - - - - - - - - - ranking = 2.6473460885217keywords = cerebral, haemorrhage (Clic here for more details about this article) |
4/1602. Twinkling artifact on intracerebral color Doppler sonography.Transcranial Doppler sonography shows potential as a noninvasive technique for long-term follow-up of treated intracranial saccular aneurysms. This technical note describes a color Doppler artifact related to microcoil architecture that might represent a potential pitfall in transcranial Doppler sonographic evaluation of aneurysmal cavity thrombosis, since it may be wrongly interpreted as residual flow or aneurysmal cavity recanalization.- - - - - - - - - - ranking = 1.377185366964keywords = cerebral, intracerebral (Clic here for more details about this article) |
5/1602. Endovascular treatment of ruptured, peripheral cerebral aneurysms: parent artery occlusion with short Guglielmi detachable coils.We report two cases of distal cerebral aneurysms that were treated by parent artery occlusion with short Guglielmi detachable coils (GDCs). One patient had a presumed mycotic aneurysm of the distal left posterior cerebral artery, and the other had a partially clipped aneurysm of the distal right anterior inferior cerebellar artery that had hemorrhaged. Short GDCs allow controlled, accurate occlusion of the parent artery at the aneurysmal neck.- - - - - - - - - - ranking = 2keywords = cerebral (Clic here for more details about this article) |
6/1602. Clinical evaluation of the effect of percutaneous transluminal angioplasty and intra-arterial papaverine infusion for the treatment of vasospasm following aneurysmal subarachnoid hemorrhage.The clinical efficacy of percutaneous transluminal angioplasty and intra-arterial papaverine infusion for treatment of vasospasm following subarachnoid hemorrhage was investigated. Between 1990 and 1993, 84 patients were treated for cerebral vasospasm in National Defense Medical College Hospital. angioplasty was performed for asymptomatic vasospasm in 18 patients and for symptomatic vasospasm in 12 patients. Intra-arterial papaverine infusion was performed for asymptomatic vasospasm in 10 patients and for symptomatic vasospasm in four patients. The other 40 patients were treated with standard conservative therapy including hypervolemic and hypertensive hemodilution. The outcomes of these patients were analyzed using the glasgow outcome scale. The outcome tended to be better for patients treated with angioplasty, but not for those treated with papaverine infusion, than for those treated conservatively. recurrence of vasospasm was more frequent after papaverine infusion than after angioplasty. Undesirable complications such as abrupt development of unconsciousness were experienced during papaverine infusion but not during angioplasty. We conclude that percutaneous transluminal angioplasty is superior to intra-arterial papaverine infusion for prevention and treatment of vasospasm following aneurysmal subarachnoid hemorrhage.- - - - - - - - - - ranking = 0.33333333333333keywords = cerebral (Clic here for more details about this article) |
7/1602. Compression of the visual pathway by anterior cerebral artery aneurysm.Visual failure is an uncommon presenting symptom of an intracranial aneurysm. It is even more uncommon in aneurysms arising from the anterior cerebral artery (ACA). We presented 2 patients with an aneurysm of the A1 segment of the anterior cerebral artery causing visual field defects. One patient presented with a complete homonymous hemianopia due to compression of the optic tract by a giant aneurysm of the proximal left A1 segment. The second patient had an almost complete unilateral anopia caused by compression of the optic nerve and chiasm by an aneurysm of the distal part of the A1 segment with a small chiasmatic hemorrhage and ventricular rupture.- - - - - - - - - - ranking = 2keywords = cerebral (Clic here for more details about this article) |
8/1602. Ask-Upmark kidney associated with renal and extrarenal arterial aneurysms.Reports of Ask-Upmark kidney, initially described as a congenital defect in renal development, are uncommon. We report a case with the features of bilateral asymmetrical segmental atrophy in a patient with childhood-onset hypertension. As an adult, she developed cerebral, celiac, and renal artery aneurysms. She underwent successful clipping of the cerebral aneurysm and renal artery repair with preservation of renal function. Novel radiologic techniques make possible the noninvasive diagnosis of segmental atrophy and its complications.- - - - - - - - - - ranking = 0.66666666666667keywords = cerebral (Clic here for more details about this article) |
9/1602. Does the tuberous sclerosis complex include intracranial aneurysms? A case report with a review of the literature.BACKGROUND: tuberous sclerosis is a protean, genetically determined disease that may involve any organ or tissue and lead to a great number of symptoms and clinical features. OBJECTIVE: diagnosis can be very difficult in cases with incomplete manifestations (formes fruste) lacking the classic signs of the disease. MATERIALS AND methods: We report a case fulfilling the diagnostic criteria for tuberous sclerosis (shagreen patches, hypomelanotic macules, renal cysts and angiomyolipomas, and "migration tracts" in the cerebral white matter) in association with a giant intracranial aneurysm, but lacking mental retardation, epilepsy and facial angiofibroma. RESULTS: Fourteen other cases of tuberous sclerosis and intracranial aneurysms, all but one without any clear sign of polycystic kidney disease, were found in the literature. CONCLUSION: We suggest that vascular dysplasias in general and aneurysms (mainly intracranial) in particular can be added to the other non-primary diagnostic features for the clinical diagnosis of tuberous sclerosis.- - - - - - - - - - ranking = 0.33333333333333keywords = cerebral (Clic here for more details about this article) |
10/1602. Aneurysm retreatment after Guglielmi detachable coil and nondetachable coil embolization: report of nine cases and review of the literature.OBJECTIVE: Guglielmi detachable coil embolization of cerebral aneurysms is becoming increasingly used to manage certain intracranial lesions based on aneurysm geometry, patient condition, and patient and surgeon preferences. Aneurysm recurrences or incomplete initial treatments are not uncommon, making repeat treatment necessary using either surgical or endovascular techniques. methods: Between January 1993 and June 1998, 1025 cerebral aneurysms were managed by the authors at a single hospital. One hundred twenty-four of these lesions were treated using Guglielmi detachable coils, and one was managed with nondetachable coils. During the follow-up period, eight patients who underwent embolization at our institution and one who underwent embolization elsewhere received repeat treatment. Five were approached surgically, and four underwent re-embolization. All charts and films were reviewed retrospectively to determine patient outcome and clinical success. RESULTS: No patient in the subgroup of this clinical study suffered a permanent complication from initial aneurysm coiling, no episodes of subsequent bleeding occurred, and no complications resulted from any subsequent therapies. The anatomic results were excellent, and all aneurysms were totally or near totally obliterated. CONCLUSION: Subtotal initial coil embolization of aneurysms can be managed safely using a variety of surgical and endovascular techniques. Our approach to this predicament, lessons we have learned, and a review of the literature are herein discussed.- - - - - - - - - - ranking = 0.66666666666667keywords = cerebral (Clic here for more details about this article) |
