Late rebleeding of ruptured intracranial aneurysms treated with detachable coils.
BACKGROUND AND PURPOSE The purpose of this study was to assess the incidence of late rebleeding of ruptured intracranial aneurysms treated with detachable coils. PATIENTS AND METHODS A clinical follow-up study was conducted in 393 consecutive patients with a ruptured aneurysm treated with detachable coils between January 1995 and January 2003. Late rebleeding was defined as recurrent hemorrha...
متن کاملIntracranial aneurysms treated with Guglielmi detachable coils: imaging follow-up with contrast-enhanced MR angiography.
BACKGROUND AND PURPOSE To compare the utility of contrast-enhanced MR Angiography (CE-MRA) with digital subtraction angiography (DSA) after endovascular treatment of intracranial aneurysms with Guglielmi detachable coils. METHODS From April 1999 to August 2002, 106 patients with 107 aneurysms treated by endovascular coiling using Guglielmi detachable coils underwent simultaneous DSA and CE-MR...
متن کاملSelective endovascular treatment of intracranial aneurysms with sapphire coils.
BACKGROUND AND PURPOSE Endovascular treatment with detachable coils is an accepted alternative to surgical clip placement for intracranial aneurysms. The purpose of this study was to evaluate the safety and reliability of the Sapphire coil, a new platinum coil for the treatment of intracranial aneurysms. METHODS Between August and September 2003, 20 consecutive patients (13 women, seven men; ...
متن کاملShort-term outcome of intracranial aneurysms treated with polyglycolic acid/lactide copolymer-coated coils compared to historical controls treated with bare platinum coils: a single-center experience.
BACKGROUND AND PURPOSE Aneurysm recanalization is an innate problem in endovascular treatment of aneurysms with coils. A coated coil system, covered with a bioabsorbable polymeric material (polyglycolic acid/lactide copolymer, PGLA), was developed to accelerate intra-aneurysmal clot organization and fibrosis. The purpose of this study was to evaluate the efficacy and safety of the PGLA-coated c...
متن کاملThree-dimensional time-of-flight MR angiography in the evaluation of intracranial aneurysms treated with Guglielmi detachable coils.
BACKGROUND AND PURPOSE Intravascular treatment of intracranial aneurysms is a relatively new therapeutic technique and long-term controlled angiographic trials are needed to assess persistence of aneurysm occlusion. Our purpose was to evaluate the effectiveness of 3D time-of-flight (3D-TOF) MR angiography as a noninvasive screening tool in the follow-up of cerebral aneurysms treated with Guglie...
