OBJECTIVE Stent-assisted coiling on intracranial aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. To achieve reconstruction of intracranial vessels with preservation of parent artery the use of stents has the greatest potential for assisted coiling. We report the results of our experiences in ruptured wide-necked intracranial aneurys...

BACKGROUND AND PURPOSE The risk factors of early hemorrhagic complications after endovascular coiling are not well-known. We identified the factors affecting early hemorrhagic complications, defined as any expansion or appearance of hemorrhage shown by head CT in the initial 48 hours after coiling. MATERIALS AND METHODS We retrospectively reviewed a series of 93 patients who underwent coiling...

Background: The umbilical cord is vital to the development, well being and survival of the fetus. A coil of the cord is defined as a complete 360 degree spiral course of umbilical vessels around Wharton’s jelly. Sonographically, the Umbilical Coiling Index (UCI) is defined as the reciprocal of the average distance between a pair of coils. Hypocoiled cords are those with UCI < 10 centile while h...

Intracranial arterial disease includes thromboembolic events, vascular stenoses, and aneurysms. Endovascular techniques have been investigated for treatment of intracranial arterial disease, as an alternative to intravenous tissue plasminogen activator and supportive care for acute stenosis and as an alternative to risk factor modification for chronic stenosis. For cerebral aneurysms, stentassi...

BACKGROUND AND PURPOSE Endovascular coiling therapy is increasingly popular for obliteration of unruptured intracranial aneurysms, but older patients face higher procedural risks and shorter periods during which an untreated aneurysm may rupture causing subarachnoid hemorrhage (SAH). We assessed trends in clipping and coiling of unruptured intracranial aneurysms, outcomes after clipping and coi...

BACKGROUND The use of a stent during the acute post-hemorrhage period is controversial. We conducted a retrospective analysis on the clinical and angiographic outcomes of the ruptured aneurysms that were embolized with stent-assisted coiling or coiling-only. MATERIAL AND METHODS We reviewed data of 279 patients with 279 ruptured intracranial aneurysms who underwent coil embolization between Jul...

Spontaneous network activity is a highly stereotyped early feature of developing circuits throughout the nervous system, including in the spinal cord. Spinal locomotor circuits produce a series of behaviors during development before locomotion that reflect the continual integration of spinal neurons into a functional network, but how the circuitry is reconfigured is not understood. The first be...

Incomplete initial occlusion rates and relatively less long-term durability remain as major problems of endovascular treatment of cerebral aneurysms. Stent-assisted coiling is a well-established current solution to overcome these problems. Double-stent treatment with a Y-configuration has been previously reported to improve the application of coiling to wide-neck bifurcation aneurysms. Herein, ...
