Intracranial aneurysms: endovascular treatment with mechanical detachable spirals in 60 aneurysms.

Abstract

Good results were obtained with EVT of intracranial aneurysms with mechanical detachable spirals. These spirals are characterized by rapid detachment and low cost.

Long-Term Follow-Up of 1036 Cerebral Aneurysms Treated by Bare Coils: A Multicentric Cohort Treated between 1998 and 2003

“…[5][6][7][8] Aneurysm occlusion at the end of the procedure was considered to be "complete" when the aneurysmal sac and neck were packed and no contrast filling the sac was detected by angiography. Occlusion was considered "near-complete" or "subtotal" when the sac was occluded but a neck remnant was observed.…”

“…[1][2][3][4][5][6][7][8][9] In many neuroradiologic centers, endovascular treatment is the first line for patients. The long-term follow-up of this technique, however, is largely unknown.…”

“…1,2 During the past 10 years, there has been significant study of the feasibility of this technique, and clinical results of EVT have been published by endovascular specialists worldwide. [2][3][4][5][6][7][8] In 2002, results of the International Subarachnoid Aneurysm Trial (ISAT) demonstrated the clinical superiority of EVT over standard surgical treatment of ruptured intracranial aneurysms. 3 Some articles have been published pertaining to the stability of occlusions treated with detachable coils and the efficacy of providing protection against growth or regrowth of the aneurysm and consequent bleeding.…”

“…3 Some articles have been published pertaining to the stability of occlusions treated with detachable coils and the efficacy of providing protection against growth or regrowth of the aneurysm and consequent bleeding. [4][5][6][7][8][9][10][11][12][13][14][15][16] Long-term follow-up and the rate of recanalization due to coil compaction, typically caused by unfavorable morphologic characteristics such as lesion and neck size, remain a disadvantage compared with surgical treatment.…”

Vascular applications of Spiral CT : an initial Experience

“…CT angiography is better than catheter angiography in the characterization of aneurysms, as it provides detailed anatomy of the dome, neck and vessel of origin of the aneurysm, this information is useful in determining the modality of treatment whether endovascular or surgical. When endovascular treatment is contemplated it is important that accurate assessment of the aneurysm sac is made in relation to the neck size, presence of calcium and parent vessel caliber as these factors directly influence the selection of embolisation material [5], this information can only be accurately provided by CT angiography with 3-D reconstructions.…”
