Histologic findings in 71 elastase-induced rabbit aneurysms embolized with platinum coils were retrospectively reviewed. Mature bone formation was found in 2 aneurysms, one with coils implanted for 3 months and the other with coils implanted for 1 year. We present the histologic findings and offer potential explanations for these observations. ...

OBJECT: Because of its thin wall, an aneurysm arising from the posterior wall of the internal carotid artery (ICA), the so-called blood blister-like aneurysm (BBA), is difficult to manage surgically and is often associated with high morbidity and mortality rates. The authors treated these aneurysms endovascularly. In this paper, they ...

Conventional embolization of cerebral aneurysms using detachable coils is time-consuming and often requires retreatment. These drawbacks have prompted the development of new methods of aneurysm occlusion. We present the fabrication and laser deployment of a shape memory (SMP) polymer expanding foam device. Data acquired in an in vitro basilar aneurysm ...

We evaluated the effectiveness of transcatheter arterial coil embolization therapy for the treatment of spontaneous hemothorax followed by aneurysm rupture in neurofibromatosis patients. Three patients were treated for massive hemothorax caused by arterial lesions associated with neurofibromatosis. Bleeding episodes were secondary to ascending cervical artery aneurysm and dissection of vertebral ...

Vascular injuries with acute arterial haemorrhage are rare but the infrequency of these complications may make their diagnosis and treatment challenging for surgeons unfamiliar with their management. In the past, surgery or coil embolisation has been used to treat these lesions; we describe the case of a pseudo-aneurysm of the ...

The authors present a case report on rebleeding of a medial cerebral aneurysm (MCA) eight years after complete endovascular coiling. The primarily successfully coiled MCA aneurysm showed a local regrowth which, however, was not the source of the rebleeding. The angiogram demonstrated no evidence of contrast filling of the coiled ...

Because the long-term security of endovascular treatments remains uncertain, a follow-up study of the patients treated in the International Subarachnoid Aneurysm Trial was performed to compare the frequency, timing, and consequences of aneurysm recurrence. Patient data were reclassified by actual treatment performed. Aneurysm and patient characteristics, including occlusion grades, time ...

Summary: After coil embolization for an aneurysm, edema surrounding the aneurysm revealed by magnetic resonance imaging (MRI) is rarely seen and is usually associated with neurological symptoms. Perianeurysmal edema was found by postoperative MRI in three out of 182 patients with cerebral aneurysm, which was treated with Guglielmi Detachable Coil ...

Summary: Whether endovascular surgery is able to reduce the mass effects of unruptured aneurysms is still controversial, although some reports have suggested efficacy in cases of internal carotid artery aneurysms with cranial nerve palsy. Here we assessed outcome in a series of cases. Between April 1992 and April 2005, 18 ...

Summary: With the existence of vasospasm, it is recommended that direct clipping surgery for a ruptured aneurysm be delayed until its disappearance, but this may be associated with aneurysmal re-rupture resulting in a poor outcome for the patients. Indications for endovascular coil embolization in such cases are discussed. Since November ...

Summary: The present series provides a balanced overview of the treatment of aneurysms in surgical clipping and coil embolization. Between January 2004 and March 2006, 76 consecutive patients with cerebral aneurysms underwent endovascular embolization and/or surgical clipping. Of these, 42 patients suffered an aneurysmal subarachnoid hemorrhage (SAH), while the remaining ...

Basilar trunk saccular aneurysms associated with fenestration are infrequent. Surgical treatment of a basilar trunk aneurysm is difficult because of its anatomic environment and complicated surgical exposure. We experienced two cases of basilar fenestration aneurysm, and the patients were treated using Guglielmi detachable coils. The usefulness of 3-dimensional digital subtraction ...

Summary: We report on a case of a 14-year-old boy with a giant serpentine aneurysm of the left internal carotid artery cavernous segment with symptoms of acute mass-effect cranial nerve dysfunction. After a balloon occlusion test of the collateral circulation, the patient underwent parent artery occlusion with platinum Guglielmi detachable ...
Kim Young Joon - - 2007
Summary: Endovascular treatment of ruptured intracranial aneurysms with detachable coils has proven a favorable alternative to surgical clipping. However, coiling has limitations in the treatment of complex or broad neck aneurysms because of possible coil prolapse or coil migration into the parent vessel and long-term angiographic recurrences. To achieve reconstruction ...

After endovascular coil embolization of cerebral aneurysms, coil compaction and late aneurysm recanalization have been ever observed. The HydroCoil Embolic System (HES) was developed to improve the packing efficacy of endovascular treatment of cerebral aneurysms. In this study, we evaluate the packing efficacy of HES using a silicone model of ...

BACKGROUND: Aneurysm recurrence is an innate problem in endovascular treatment of aneurysms with coils. A coated coil system named Matrix (Boston Scientific Neurovascular, Fremont, CA), covered with a bioabsorbable polymeric material (polyglycolide/lactide copolymer [PGLA]), was developed to accelerate intraaneurysmal clot organization and fibrosis. The purpose of this study was to ...

BACKGROUND: Coiling of intracranial aneurysms with platinum coils sometimes results in relatively poor angiographic results which may be is related to low packing volumes achieved. Hydrogel coated expandable coils (HydroCoil) have been shown to achieve better aneurysm volume filling which may potentially result in lower recanalization rates. Currently there is ...

Coil migration is a rare but potentially serious complication of endovascular procedures. Occasionally coils can be retrieved via endovascular techniques. The authors describe the microsurgical management of a case in which endovascular techniques failed. A 2-year-old girl with pulmonary atresia and a Blalock-Taussig shunt underwent attempted endovascular closure of the ...

OBJECT: The HydroCoil embolization system is a helical platinum coil coated with a polymeric hydrogel that expands when it contacts aqueous solutions to increase filling volumes, improve mesh stability, and possibly elicit a healing response within the aneurysm. In this paper, the authors report the 1-year recurrence and complication rates ...
König R W - - 2007
OBJECTIVE: Endovascular treatment of cerebral aneurysms with detachable coils has proven to be a save and effective treatment. But long-term recurrence due to aneurysm regrowth or coil compaction has been reported in up to thirty percent of cases. Therefore a growing number of previously coiled aneurysms have to be retreated ...

In recent years, technical developments have made endovascular procedures attractive therapeutic options and enabled the endovascular surgeon to redefine the management of cerebral aneurysms. However, as the number of aneurysms undergoing endovascular therapy has grown, so has the number of patients with incompletely treated aneurysms who are presenting for further ...
Jeong Je Hoon - - 2007
OBJECTIVE: The presence of an intracerebral hematoma from a ruptured aneurysm is a negative predictive factor and it is associated with high morbidity and mortality rates even though clot evacuation followed by the neck clipping is performed. Endovascular coil embolization is a useful alternative procedure to reduce the surgical morbidity ...
Thorat Jayant Daniel - - 2007
Neuroendovascular treatment is increasingly being used for treatment of intracranial aneurysms. Postradiation alopecia, commonly seen weeks after radiation for other diseases such as brain tumors, is rarely reported after neuroendovascular procedures for benign lesions because of their delayed manifestations. Although the morbidity and mortality is less compared with surgery, adverse ...

By using images created with 3D rotational angiography or CT angiography as templates, it is possible to place anatomically correct curves on microcatheters, curves that reproduce the complex 3D vascular anatomy of individual patients. Catheters so curved conform to the anatomy of arteries leading to aneurysms and are less likely ...
