The anatomical complexity of the paraclinoid region has made surgical treatment of intracranial ophthalmic segment aneurysms (OSAs) difficult. This study evaluated the safety and efficacy of endovascular treatment of paraclinoid aneurysms. We conducted a retrospective study of 28 patients with 30 aneurysms of the paraclinoid in whom treatment with endovascular techniques was attempted. Patient age, sex, presence of subarachnoid hemorrhage, aneurysm type, size of aneurismal sac and treatment modality were reviewed. Clinical evaluation and control angiography were performed between one and 43 months. Overall, complete occlusion was obtained in 26 aneurysms (86.6%), nearly complete (>90%) occlusion in two aneurysms (6.7%) and incomplete occlusion was observed in two aneurysms (6.7%). All endovascular techniques were successful. Procedure-related complications were observed in two patients (7.1%). Patients underwent follow-up for a mean of 14.8 months (range 1-43 months). Repeated coil treatment was performed in one patient. One patient died of massive brain infarction six days postoperatively and thus no follow-up data were available for this case. In 27 patients with follow-up studies, aneurysm closure was complete in 22 (81.5%) and incomplete in five (18.5%). Endovascular treatment is a safe and efficient alternative approach for paraclinoid aneurysms. 相似文献

Atherosclerosis accounts for 90% of the cases of renal artery stenosis. It is an important cause of secondary arterial hypertension by means of inducing the renin-angiotensin system, volume expansion, and sympathetic activation. Despite high procedural success rate of renal artery stenting, clinical trials have shown an inconsistent outcome about improvement in hypertension. The accurate predictors identify the good indication for renal artery stenting is clinically needed. Currently, the presence of hemodynamically critical stenosis causing renal ischemia, the presence of symptoms with undoubtedly benefit from revascularization, and the assessment of procedural risk are key factors for decision making about indication of renal artery stenting. 相似文献

We report the clinical and angiographic results of endovascular treatment of unruptured intracranial aneurysms. Over a three-year period, 80 unruptured aneurysms in 74 patients were electively treated with endovascular management. One aneurysm was diagnosed during investigations for a second ruptured aneurysm, 54 aneurysms were incidentally discovered, 18 aneurysms presented with symptoms of mass effect and seven aneurysms presented with symptoms of brain stem ischemia. Mean size of the 80 unruptured aneurysms was 12.5±8.0 mm (range, 2-39 mm). Thirty-six aneurysms (45%) were small (<10 mm), 38 aneurysms (47.5%) were large (10-25 mm), and six aneurysms (7.5%) were giant (25-39 mm). Forty-eight wide-necked aneurysms (60%) were coiled with the aid of a supporting device. The mortality rate was 1.25%, and the overall morbidity was 1.25%. Of these, one of the patients suffered a stroke, leading to severe disability (1.25%). In one patient, the aneurysm ruptured during treatment, resulting in death. Initial aneurysm occlusion was complete (100%) in 76.25% aneurysms, nearly complete (90%-98%) in 10% aneurysms and incomplete (60%-85%) in 13.75% aneurysms. Follow-up angiography was available in 67 patients with 73 treated aneurysms (91.25%) from one to 36 months (mean 9.3 months); partial reopening occurred in 7.5%, mainly large and giant aneurysms (5.5%). Additional coiling was performed in four aneurysms. There were no complications in additional treatments. At 14.1-month clinical follow-up (range, 2 to 36 months), mRS score was 0 in 78.75% patients, 1 in 10% patients, 2 in 8.75% and 3 in 1.25%. There was no aneurysmal rupture during the follow-up period. Endovascular treatment of unruptured intracranial aneurysms has low procedural mortality and morbidity rates. 相似文献

Tentorial dural arteriovenous fistula (DAVF) is a rare vascular disease, which accounts for less than 4% of all cases of intracranial DAVF. Because of the high risk of intracranial hemorrhage, patients with tentorial DAVF need aggressive treatment. Management approaches are still controversial, and endovascular treatment has emerged as an effective alternative. In the current work, we describe our experience with the endovascular approach in the treatment of these deep and complex DAVF of the tentorium. Eight patients were treated between January 2006 and July 2009. Six patients (75%) presented with intracranial hemorrhage related to the DAVF rupture. Four patients (50%) had subarachnoid bleeding and two had intraparenchymal hematoma. Endovascular treatment was performed via the transarterial route alone in five cases (62.5%), by the transvenous approach in two cases (25.0%) and in a combined procedure using both arterial and venous routes in one patient (12.5%). Complete obliteration of the fistula was achieved in all cases. The outcome at 15 months was favorable (modified Rankin scale 0-3) in seven (87.5%) patients. Complete cure of the lesion was confirmed in these cases. This paper reports on the effectiveness of endovascular treatment in tentorial DAVF management. The choice of the venous versus the arterial approach is determined by regarding different anatomical dispositions. 相似文献

The endovascular treatment of intracranial aneurysms 3 mm or less is considered controversial. The purpose of this study is to report angiographic and clinical results following coiling of such aneurysms and compare them to those of larger aneurysms (> 3 mm).Between November 1999 and November 2009 endovascular treatment was attempted in 956 consecutive intracranial aneurysms. Of 956 aneurysms, 111 aneurysms were very small aneurysms with a maximal diameter of 3 mm or less. We conducted a retrospective analysis of angiographic and clinical outcome following coiling of very small aneurysms and subsequently comparing it to the results of larger aneurysms.Coiling initially failed in eight aneurysms. In the remaining 103 aneurysms endovascular treatment was accomplished and immediate angiographic results showed complete aneurysm occlusion in 43 aneurysms, nearly complete aneurysm occlusion in 54 aneurysms and less than 90% aneurysm occlusion in six aneurysms. Complications occurred in the treatment of 15 aneurysms, including eight procedural ruptures, six thromboembolic events and one case of early hemorrhage. Compared with larger aneurysms, treatment of very small aneurysms was associated with a higher rate of procedural ruptures (7.2% versus 4.4%) and procedural mortality (4.7% versus 2.7%) but a lower procedural morbidity (1.9% versus 4.0%). However none of these differences reached statistical significance (p = 0.186, p= 0.388, respectively). The retreatment rate was higher for the larger aneurysms (8.2% and 6.3%), but this was not significant either (p= 0. 496). At nine-month follow-up significantly more small aneurysms were found to have a stable occlusion grade compared to large aneurysms.Endovascular treatment of very small aneurysms is feasible with a lower retreatment rate compared to large aneurysms (> 3 mm). However the data also suggest that endovascular treatment of very small aneurysms might be associated with an increased risk of procedural ruptures and mortality. At nine-month follow-up results indicate significantly less compaction in the very small aneurysms. 相似文献

The acute management of aneurysmal SAH requires a comprehensive approach entailing acute critical care and stabilization, occlusion of the aneurysm, and intensive care management of acute neurologic complications. The development of endovascular treatment of aneurysms has added an important, less-invasive treatment to the regimen available in treating aneurysms. An integrated approach of providing critical care before, during, and after the occlusion of the aneurysm is an important concept that should be the goal. Debate and controversy remains regarding which aneurysms are best suited to endovascular treatment or to surgical treatment; an evolving experience and clinical trials will provide further guidance. Nonetheless, some aneurysms may require both surgery and endovascular treatment. Finally, close neurologic observation and directed specialized monitoring techniques are required for providing directed critical care in the acute period after SAH. 相似文献

目的探讨应用血管内支架治疗锁骨下动脉起始段狭窄或闭塞的有效治疗方法。方法局麻下,以Seldinger技术穿刺股动脉,置入8F导管鞘,全身肝素化,用5F Pigtail导管、单弯导管行主动脉弓及全脑血管造影。将8F导引导管置于病变锁骨下动脉近端,选择合适球囊扩张狭窄部位。撤出球囊导管,将支架递送系统沿导丝送入狭窄段,路图下准确定位并释放支架。对于锁骨下动脉闭塞患者,将8F导引导管置于闭塞锁骨下动脉近端,用泥鳅导丝小心反复试探至通过闭塞段,再重复上述步骤。若导丝始终不能通过闭塞段,则行肱动脉逆行穿刺,置入7~8F导管鞘,用泥鳅导丝在单弯管配合下小心反复试探逆行开通闭塞段,同法行逆行球囊扩张与支架置入。结果 15例成功植入支架,1例未成功;支架植入后所有患者肱动脉及桡动脉搏动良好,临床症状改善;成功植入支架的15例中有1例12个月后再狭窄,再次植入1枚支架,其余患者随访24个月未见再狭窄;所有患者围手术期未见与手术有关的并发症。结论应用血管内支架治疗锁骨下动脉狭窄或闭塞是一种微创、安全、有效的治疗方法,有望成为主要的治疗手段。 相似文献

ObjectiveThe objective of this study was to evaluate the feasibility and outcomes of transvenous endovascular embolization (TVE) for superficial intracranial arteriovenous malformations (AVMs).MethodsAfter collecting clinical and imaging data, a prospective series of 11 patients presenting with superficial AVMs were treated by endovascular embolization using a transvenous approach between November 2016 and October 2018.ResultsTen patients (90.9%) had ruptured AVMs before TVE. The mean nidus size was 3.27 ± 1.47 cm, and the median Spetzler-Martin grade was II. The rate of immediate angiographic occlusion of the AVMs was 90.9% (10/11). One patient was treated with transarterial embolization since TVE was not achieved due to an unsuccessful positioning of the microcatheter. Two patients (cases 8 and 11) suffered a intracranial hemorrhage and a cerebral infarction with encephaledema, respectively, but no procedure-related mortalities were observed. Eight patients (72.7%) were independent with a modified Rankin Score (mRS) ≤ 2 at discharge and the mRSs of all patients, which were collected 30 days postintervention, were not more than 2. The mean follow-up period was 17 months. There were no nidus recurrences during the follow-up period.ConclusionsThe curative transvenous embolization of superficial AVMs seems feasible and effective while carefully monitoring for embolization-related complications. 相似文献

Arteriovenous malformations are direct communications between the arterial and venous circulations without the usual passage through the capillary net. They are the most frequent type of malformations of the intracranial circulation and the second most frequent cause of intracranial hematomas or hemorrhage. We report on a 7-year-old girl with intracerebral hematoma following acute rupture of an arteriovenous malformation. The girl experienced a spontaneous headache and later became unconscious. At the time of admission to the hospital, her neurological status scored 5 on the Glasgow Coma Scale. Computerized tomography of the brain revealed a round hyperdense lesion in the left frontoparietal region. Digital subtractional angiography of the left internal carotid artery confirmed the suspicion of an arteriovenous malformation with one main feeding artery: a distal branch of the left anterior cerebral artery. The nidus was round and about 2 cm in diameter. The venous drainage was of the superficial type, flowing into the left superior sagittal sinus. After consultation with a neurosurgeon, we decided to treat the arteriovenous malformation by means of an endovascular technique. A flow-guided catheter was placed close to the nidus. Control angiography before embolization revealed the proper position for the injection of embolic material. We used the conventional mixture of acrylic polymerization glue, Lipiodol oil contrast medium and particles of tantalum powder. Control angiography at the end of the procedure revealed complete occlusion of the malformation. There were no signs of potential new feeding arteries that could appear as a result of changed hemodynamic conditions after embolization. Endovascular treatment of arteriovenous malformations could become the treatment of choice for these lesions, especially in combination with radiosurgery. The established microsurgical treatment is very effective but carries a higher risk of hemorrhagic complications. 相似文献

AbstractA 59-year-old female presented to our institution with paraparesis caused by medullar compression secondary to multiple myeloma. Spinal cord decompression and transpedicular spine fixation were performed. A month later, the patient complained of sudden pain in her middle back. A CT scan revealed screw impingement on the aortic wall at T8 level. A thoracic stent-graft was deployed before removing the fixation. The patient had an uneventful postoperative course, without complications during the four-year follow-up. In this case report, stent-graft placement proved to be safe and effective in avoiding bleeding during screw removal. 相似文献

Endovascular stent implantation is a rapidly emerging technology for treatment of arterial obstructions in the entire circulation. During recent years, several randomized studies evaluated the effects of stenting in lower limb arteries. We herein provide an overview on data of trials in the iliac and femoropopliteal vessel area discussing the benefits and limitations of endovascular stents. In the iliac arteries, midterm and long-term data from one randomized trial including analysis on patency, clinical outcomes, cost-effectiveness and quality of life indicate that balloon angioplasty with selective stenting remains the therapy of choice for endovascular revascularization. In the femoropopliteal arteries, balloon-expanding stents were not superior to balloon angioplasty for treatment of short lesions, and self-expanding nitinol stents also failed to show a beneficial effect in short lesions below 5 cm. However, including longer lesions, one randomized trial indicated a beneficial effect of nitinol stents in lesions with a median length around 10-12 cm. Further studies and longer follow-up intervals are needed to confirm these data. Meanwhile, balloon angioplasty with optional stenting also remains the recommended endovascular approach for the femoropopliteal segment. 相似文献
