Abstract
BACKGROUND: The objective of this work is to analyze the effectiveness of Penumbra 400 micro-coils in the embolization of large cerebral aneurysms. MATERIAL AND METHODS: A retrospective analysis has been conducted in a group of 32 patients at the average age of 54.5 years (30-84) for whose embolization the P400 micro-coils (P400) have been used. A control group consisted of 44 patients at the average age of 52.7 years (24-82) in whose aneurysm embolization the 18 micro-coils (MC) have been utilized. RESULTS: The respective percentages of micro-coil packing density in aneurysm sacs were 31.5% for P400 and 29% for MC. The average P400 fluoroscopy time was 21min, and 34min in case of MC. The average number of used micro-coils was 3.9 for P400 and 5.6 for MC. The radiation dose received by a patient was 1.7Gy/2.2Gy, respectively. The recanalization of P400 has occurred in 14/31 cases (45%), and for MC it has occurred in 23/44 (52%) patients. One patient died due to early recanalization after P400 aneurysm embolization. CONCLUSION: Procedures with use of the P400 demonstrate minimally higher effectiveness of large aneurysms embolization in comparison with the MS with a not much shorter duration and reduction of a radiation dose that a patient receives.
