Rinkel Gabriel J E - - 2009
Treatment of patients with aneurysmal subarachnoid haemorrhage not only involves securing the aneurysm by endovascular coiling or surgical clipping but also prevention and treatment of the medical and neurological complications of the bleed. These acutely ill patients should be looked after in specialised centres by a multidisciplinary team that is ...

Haemodynamics is believed to play an important role in the initiation, growth and rupture of intracranial aneurysms. In this context, computational haemodynamics has been extensively used in an effort to establish correlations between flow variables and clinical outcome. It is common practice in the application of Dirichlet boundary conditions at ...

OBJECTIVE: Resection of the anterior clinoid process (ACP) for the clipping of an internal carotid-posterior communicating artery aneurysm is rarely needed. However, preoperative awareness of the necessity of anterior clinoidectomy is essential for safe clipping of the lesions. We investigated the preoperative predictive value for anterior clinoidectomy in treating internal ...

INTRODUCTION: High-flow extracranial-intracranial (EC-IC) bypass and aneurysm trapping constitutes a well-known surgical solution for internal carotid artery (ICA) aneurysms that are not amenable to clip ligation or endovascular therapy. The advantages of the radial artery (RA) as a conduit for myocardial revascularization have become widely accepted, with a better patency ...

Intracranial arteriovenous malformation (AVM) associated with aneurysm has been infrequently encountered and the treatment for this malady is challenging. We report here on our clinical experience with AVMs associated with arterial aneurysms that were managed by multimodality treatments, including clipping of the aneurysm, microsurgery, Gamma-knife radiosurgery (GKS) and Guglielmi detachable ...

Persistent sciatic artery (PSA) is a rare congenital vascular anomaly that leads to aneurysmal degeneration and atherosclerotic changes. A careful understanding of the embryology is mandatory as variations in vascular development determine the optimal treatment. We present a case of an 85-year-old female who was incidentally found to have a ...

OBJECTIVES: Coexisting intracerebral aneurysms and meningiomas occur relatively rarely, without a clear relationship, although an aneurysm can be located within a meningioma. The aim of this retrospective study was to identify possible explanations for the coexistence of these conditions and to present a rationale for treatment strategies. PATIENTS AND METHODS: ...
Behari Sanjay - - 2009
BACKGROUND: Basilar apex aneurysms (BAA) are located in interpeduncular cistern surrounded by eloquent neurovascular structures. Surgical access is difficult due to narrow surgical corridors and requires traversing through a depth of 6-8 cm of subarachnoid space. AIM: Surgical management of BAAs clipped using frontotemporal craniotomy, orbitozygomatic osteotomy with combined subtemporal ...

Multiple major artery compression by an aortic aneurysm is extremely rare in the paediatric population. Most arterial aneurysms in children are secondary to infections mainly mycotic, connective tissue disorder, vasculitis, collagen vascular diseases, and other causes. True idiopathic aneurysms are the least common and a few reports in children have ...

Fusiform aneurysms of the basilar artery present difficult challenges for the treating physician. On one hand, these aneurysms are difficult and dangerous to treat. On the other, the relatively high rupture rate, risk of thromboemboli, and the frequent presence of mass effect on the brainstem often demand treatment rather than ...
Karthekeyan B Ranjith - - 2009
Tracheal and esophageal compression is a well-recognized complication of aneurysms of the aortic arch. Most of the patients present with dysphagia and/or respiratory insufficiency. In the adult population a right-sided aortic arch is often asymptomatic unless aneurysmal disease develops. This usually occurs at the level of the take-off of an ...
Hacein-Bey L - - 2009
Septations within cerebral arteries or aneurysms are exceedingly rare in the absence of associated fenestrations. We report an unusual unruptured pedunculated basilar apex aneurysm, with a "pseudoseptation" between the main aneurysmal sac and an anterior compartment, which was, in fact, represented by a perforation in the membrane of Liliequist, permitting ...
Shirani Mohamad - - 2010
Posterior inferior cerebellar artery (PICA) aneurysms are relatively uncommon, comprising only 0.5-3% of all intracranial aneurysms. Distal PICA aneurysms are much more uncommon, with more than 200 cases being reported in the literature. The finding of an extracranially located aneurysm of distal PICA is considered a true rarity. A rare ...
van Rooij S B T - - 2009
BACKGROUND AND PURPOSE: Fenestrations of intracranial arteries are variants resulting from incomplete fusion of primitive vessels. An association with aneurysms is suggested in many studies. On conventional angiography, fenestrations are rarely visible. 3D rotational angiography (3DRA) provides improved visualization of cerebral vessels from any desired angle. We used 3DRA to ...

Ruptured aneurysms located at the non-branching sites of the internal carotid artery, including blister-like aneurysms, possess unique clinical and technical features. This report presents nine consecutively managed patients with these types of aneurysm, detailing the clinical and radiological characteristics and surgical outcomes. The initial angiography identified aneurysmal lesions in six ...
Aarhus Mads - - 2009
Working with patients with intracranial aneurysms, we have developed a clinical suspicion that there may be differences in the rupture rate of aneurysms depending on the aneurysm's anatomical location. The aim of the study was to examine the anatomical distribution of ruptured and unruptured intracranial aneurysms in a defined population. ...

Segal and McLaurin first described giant serpentine aneurysms, based on their distinct angiographic features, in 1977. These lesions are >or= 25 mm, partially thrombosed aneurysms with a patent, serpiginous vascular channel that courses through the aneurysm. There is a separate inflow and outflow of the aneurysm, of which the outflow ...

Most cavernous carotid aneurysms (CCAs) are considered benign lesions, most often asymptomatic, and to have a natural history with a low risk of life-threatening complications. However, several conditions may exist in which treatment of these aneurysms should be considered. Several options are currently available regarding the management of CCAs with ...

Aneurysmal subarachnoid hemorrhage continues to have high rates of morbidity and mortality for patients despite optimal medical and surgical management. Due to the fact that aneurysmal rupture can be such a catastrophic event, preventive treatment is desirable for high-risk lesions. Given the variability of the literature evaluating unruptured aneurysms regarding ...
Bambakidis Nicholas C - - 2009
Aneurysms of the anterior inferior cerebellar artery (AICA) are relatively rare among intracranial aneurysms. They can occur in 1 of 3 regions of the AICA: 1) craniocaudal (high or low riding), 2) mediolateral-premeatal (proximal), and 3) meatal-postmeatal (distal). The management strategies for treatment differ according to the location and configuration ...
