BACKGROUND AND PURPOSE Coiling is increasingly used as treatment for intracranial aneurysms. Despite its favorable short-term outcome, concerns exist about long-term reopening and inherent risk of recurrent subarachnoid hemorrhage (SAH). We hypothesized a higher risk for recurrent SAH after adequate coiling compared with clipping. METHODS Patients with ruptured intracranial aneurysms coiled b...

OBJECTIVES Using specific selection criteria to determine whether endovascular coiling as compared to neurosurgical clipping is associated with significant benefits, in terms of 1-year clinical outcomes and consumption of hospital resources, for the treatment of ruptured intracranial aneurysms in Hong Kong Chinese patients. DESIGN Retrospective study. SETTING University teaching hospital, H...

Changes in coiling direction in foraminifera have been used extensively as proxy data for paleoclimates. However, most of the studies centred around plantkonic foraminifera, and various causes (including reproductive mode) were suggested for coiling direction changes. We explored the relationship between mode of reproduction and coiling directions in benthic foraminifera. Benthic foraminiferal ...

BACKGROUND AND PURPOSE To determine the hospital mortality rates associated with elective surgical clipping and endovascular coiling of unruptured intracranial aneurysms. METHODS We identified a cohort of patients electively admitted to US hospitals with the diagnosis of unruptured intracranial aneurysm from the National Inpatient Sample database for the years 2000 through 2006. Patient demog...

BACKGROUND AND PURPOSE Endovascular and surgical options are both available for treatment of ruptured cerebral aneurysms. Knowledge of the costs relative to Medicare reimbursement for hospitalization of these patients is important for understanding the economic impact of these patients on hospitals. MATERIALS AND METHODS Using the NIS, we identified hospitalizations for clipping and coiling o...

The manner in which a gastropod shell coils has long intrigued laypersons and scientists alike. In evolutionary biology, gastropod shells are among the best-studied palaeontological and neontological objects. A gastropod shell generally exhibits logarithmic spiral growth, right-handedness and coils tightly around a single axis. Atypical shell-coiling patterns (e.g. sinistroid growth, uncoiled w...

OBJECTIVE A cost comparison of the surgical clipping and endovascular coiling of unruptured intracranial aneurysms (UIAs), and the identification of the principal cost determinants of these treatments. METHODS This study conducted a retrospective review of data from a series of patients who underwent surgical clipping or endovascular coiling of UIAs between January 2011 and May 2014. The medi...

BACKGROUND This article reported the experience of endovascular treatment in giant middle cerebral artery (MCA) aneurysms with parent artery occlusion or stent-assisted coiling. MATERIAL AND METHODS Eleven consecutive patients with giant MCA aneurysms were included. The aneurysms predominantly involved the M1 segment in two cases, bifurcation in four cases, and M2 in five cases. Four M2 fusif...

To describe our initial experience and early outcomes with distal placement of the Neuron 6F guiding catheter through coiled ICA for aneurysmal EVT. We examined the utility of the Neuronf 70 6F guiding catheter for the embolization procedure in such cases, fourteen cases of aneurysm with coiling of the parent ICA are presented via traditional guiding catheters. With the support of 8F ENVOY guid...

Coexistence of cerebral aneurysm and carotid artery disease may be encountered in clinical practice. Theoretical increase in aneurysmal blood flow may increase risk of rupture if carotid artery disease is treated first. If aneurysm coiling is performed first, stroke risk may increase while repeatedly crossing the diseased artery. It is controversial which disease to treat first, and whether it ...
