BACKGROUND AND PURPOSE The purpose of this study was to assess the incidence of early rebleeding after coiling of a ruptured cerebral aneurysm, assess the clinical outcome, and identify risk factors for this event. METHODS Early rebleedings occurred in 6/431 (1.4%) consecutive patients after coiling of a ruptured aneurysm. Clinical condition at the time of treatment, aneurysm location and siz...

In this paper we introduce and analyze a set of equations to study geometric and energetic aspects associated with the kinematics of multiple folding and coiling of closed filaments for DNA modeling. By these equations we demonstrate that a high degree of coiling may be achieved at relatively low energy costs through appropriate writhe and twist distribution, and independently from the number o...

INTRODUCTION The purpose of this study was to define gross patterns of umbilical cord hypercoiling and determine correlations with histological features in the placenta and/or perinatal outcomes such as stillbirth. METHODS Gross images of placentas with hypercoiled umbilical cords (>3 coils/10 cm) were assigned a major umbilical coiling pattern and the direction (right or left) of the coiling...

Thromboembolic events are known complications of endovascular coiling of intracerebral aneurysms. We report a case of a 50-year-old patient whose ruptured middle cerebral artery aneurysm was treated with endovascular coiling, which was complicated by occlusion of the inferior M2 trunk during the procedure. An emergency craniotomy was performed to enable coil retrieval, evacuation of the thrombu...

BACKGROUND More than 200 aneurysms have been coiled at the UIC Medical Center within the last 5 years. We describe in detail the technical factors that increase the chance of complete occlusion of a cerebral aneurysm with coils. Aneurysms selected for coiling have good geometry or are in a location that is difficult to reach surgically. Patients with medical conditions that preclude surgical tr...

BACKGROUND AND PURPOSE Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. We present our experience with stent-assisted coiling with special emphasis on procedure-related neurological complications and incid...

See related article, pages ●●●–●●● Early aneurysm repair to prevent recurrent bleeding is central to the management of patients with subarachnoid hemorrhage. Over the past 15 years, endovascular occlusion of cerebral aneurysms has emerged as an alternative to microsurgical clipping, and the relative merits and shortcomings of these 2 approaches have been the subject of considerable discussion i...
