Abstract

This study presents the assessment results of coil length characteristics according to the volume of cerebral artery among the inpatients that received angiography and coil embolization following intracranial aneurysm from March, 2010 to September 2011. The volume rendering method was applied to the patients that received embolization to their cerebral arteries to obtain volume measurements. After coil embolization, the volume ratios were calculated with the volumes and lengths of coils. The embolic volume ratios were $43.11{\pm}3.11%$, $36.07{\pm}2.03%$, 40.91%, and 38.25% when the aneurysm sizes were 6mm or less, 6~10mm, 10~15mm and 20mm or more, respectively, being similar to the recommended volume ratios. Regardless of the types of aneurysm, the coil length according to volume was 0.65cm per $1mm^3$ of 20~$100mm^3$ when one type of 0.25mm diameter coil was used. They were 0.62cm per $1mm^3$ of 20~$150mm^3$ when one type of coil was used in the aneurysm volume of the saccular type and 0.60cm per $1mm^3$ of 20~$90mm^3$ when one type of coil was used in the aneurysm volume of the multi-lobulated type.
