Coiling of the artery is a rare morphologic entity, most frequently found in the internal carotid arteries. Coiling of other arteries is rarely reported because it is usually asymptomatic. We report a case of 360 degrees coiling of the right external iliac artery found by color duplex scan and arteriography. ...

BACKGROUND: The Guglielmi Detachable Coil introduced by the Boston Scientific Corporation has been widely used for endovascular coiling of aneurysm. Recently, Sapphire platinum detachable coils (eV3, Irvine, CA) have been introduced for aneurysm coiling. Herein, we report our clinical experience with the Sapphire coil to evaluate the incidence of coil ...

The authors present an extremely rare case of kissing aneurysms associated with fenestration of the distal basilar artery. The two aneurysms were successfully treated with endovascular coil embolization. We provide two-dimensional (2D) and three-dimensional (3D) angiographic features of the kissing aneurysms, and procedural details of coil embolization. To the best ...

Primary endovascular intervention is increasingly the first choice of treatment for cerebral aneurysms, particularly for those with complex anatomy in the posterior circulation. However, their clinical management and follow-up continue to be predominantly in the hands of neurosurgeons. In this report, the development of alopecia following the coiling of posterior ...
Nishino Kazuhiko - - 2007
INTRODUCTION: In coil embolization of a posterior circulation aneurysm, tortuosity or a small vessel caliber frequently prevents placement of a guiding catheter in the vertebral artery. Even in such difficult situations, however, coil embolization is the only treatment option when the patient's clinical condition is very poor, or the aneurysm ...

Bowel ischemia can complicate treatment of type II endoleak with liquid or semiliquid agents such as n-butyl cyanoacrylate (NBCA) if nontarget embolization of the inferior mesenteric artery (IMA) occurs. The current report describes four cases of type II endoleak in which the IMA was the main outflow vessel and was ...

Endovascular occlusion of the aneurysm was performed by ...
Richling Bernd - - 2006
Endovascular therapy has continuously evolved since it was first described in 1904. It was first used as a technique to inject particles to follow the flow into vascular lesions, and from the mid-seventies on, microballoons were developed to reach targets in the arterial vascular tree. Arteriovenous malformations were approached with ...

HydroCoil (MicroVention, Aliso Viejo, CA, USA) is a self-expanding detachable coil developed to improve the endovascular occlusion of intracranial aneurysms. The hydrogel polymer covering the microcoil expands to several times its original diameter to enhance thrombosis of the intended vessel. We made use of this new technology to occlude a ...
Suzuki Sachio - - 2006
Application of endovascular surgery for very small aneurysms is controversial because of technical difficulties and high complication rates. The aim in the present study was to assess treatment results in a series of such lesions at one institution. Since 1997, endovascular surgery has been advocated for very small ruptured aneurysms ...
Kwon Hyon-Jo - - 2006
BACKGROUND: Small cerebral aneurysms embolized with only 1 or 2 detachable coils often seem unstable and unsatisfactory. We tried to assess the long-term results of such embolized aneurysms. METHODS: Among 231 intracranial saccular aneurysms embolized at the Asan Medical Center between July 1995 and July 2004, 27 small aneurysms were ...

Ross Ian B - - 2006
BACKGROUND: The technique of BAC is attractive because the balloon theoretically allows for (1) "control" of blood flow in the vessel; (2) improved stability of the microcatheter in the aneurysm; (3) denser packing with coils; and (4) improved delineation of the neck of the aneurysm. The purpose of this communication ...
Yuzawa Izumi - - 2007
BACKGROUND: Endovascular surgery is being increasingly used as an alternative to craniotomy clipping surgery, especially for aged patients and complicated cases. However, tortuous atherosclerotic arteries sometimes interfere with advancement of catheters so that direct puncture may be necessary. Short guiding catheters for use with this approach have been newly developed, ...
Yi H J - - 2006
BACKGROUND AND PURPOSE: Despite systemic heparinization, thromboembolic complications remain a major concern related to endovascular treatment of intracranial aneurysms. We assessed the safety of intravenous eptifibatide administered during aneurysm coiling procedures to prevent such complications. METHODS: From August 2001 to November 2004, 298 coil embolization procedures were performed to treat ...

The publication of the ISAT trial in 2002 has resulted in increasing numbers of patients with aneurysmal subarachnoid haemorrhage undergoing endovascular coiling, as first line treatment for aneurysm occlusion. During the first 2-year period post-ISAT, in which all suitable intracranial aneurysms were coiled first, we had to perform surgery in ...

Ultrasound-guided compression and thrombin injections are reliable for the management of small and medium-sized false aneurysms. However, owing to technical limitations, large false aneurysms often necessitate surgical intervention, which is associated with significant postoperative morbidity and mortality. Endovascular coil embolization is an evolving minimally invasive technique that can be used ...
Fitzpatrick Darren - - 2006
The authors describe the endovascular management of a ruptured wide-necked basilar terminus aneurysm with stent-assisted coil technique via posterior communicating collateral vessels from the anterior cerebral circulation. A Neuroform stent was placed horizontally across the neck of the aneurysm with use of the patient's large, patent, posterior communicating artery. This ...
Krings Timo - - 2006
OBJECTIVE: Treatment strategies of cerebral aneurysms include surgical clipping and endovascular therapies. To determine the long-term results of these therapeutic strategies, the vessel wall reaction close to the former aneurysm was studied according to the assumption that an intact endothelial layer over the former aneurysm neck constitutes complete vessel wall ...

We report a case of a 55-year-old man carrying two unruptured internal carotid artery (ICA) wide-neck aneurysms. In the same session, the smaller aneurysm was treated by coils using the remodeling technique and the large aneurysm was treated by stent-assisted coil embolization. During the stent-assisted procedure for the large aneurysm, ...

We report upon our experiences of the CAGDC in treating aneurysms with an assessment of its efficacy and safety. METHODS: The effect of CAGDC of wide-necked aneurysms was retrospectively ...
Trinidad-Hernández Magdiel - - 2006
We report the unusual case of a woman with a saccular aneurysm of the distal cervical internal carotid artery arising just distal to a kink and a 360 degrees redundant loop. The retromandibular position of the aneurysm would have mandated a complex surgical procedure. A purely endovascular approach was not ...

OBJECTIVE: Intradural pseudoaneurysms have a malignant natural history and can be difficult to treat if parent vessel deconstruction is not feasible. These lesions often involve a long arterial segment and lack a defined saccular component that would safely accommodate the introduction of embolization coils. The current report describes the successful ...

In a 71-year-old man with a history of coronary artery bypassing using the left internal thoracic and gastroepiploic arteries, the first jejunal artery aneurysms were found by chance at 3D-CT performed to evaluate conditions of the grafts. He was successfully treated by transcatheter embolization using interlocking detachable coils. During a ...

Intraventricular haemorrhages (IVHs) caused by bleeding aneurysms are critical conditions that often carry a severe prognosis. Two main problems must be urgently dealt with: the secondary damage caused by intraventricular clotting and the risk of early rebleeding. A protocol of ultra-early endoscopic ventricular evacuation, after securing the aneurysm with coils, ...
