ROBLES, Miguel et al. Tratamiento endovascular de aneurismas cerebrales asintomáticos: análisis de una serie de 118 casos. Rev. argent. neurocir. [online]. 2009, vol.23, n.1, pp. 15-22. ISSN 1850-1532.
Objective. To analyze results in a series of unruptured aneurysms treated with endovascular technique and discuss the indication for treatment. Material and methods. Retrospective analysis of a series of 118 unruptured aneurysms in 96 patients treated by embolization with coils or stent assisted coils during four and a half year period. Results. One hundred and fifteen aneurysms were successfully embolized with 78% of total or almost total occlusion rate. Fifteen procedural (12.7%) complications occurred causing definite mobidity in 3 (3.1%) patients and two (2.1%) deaths. One of the embolized aneurysms (0.8%) bled one hour after the precedure. Conclusion. Embolization of unruptured aneurysms is associated to low morbidity and mortality rates in comparison with most recent reports on natural history and open surgery results. Anyhow treatment indication will depend on the analysis of patient qualification (age, clinical status, life expectancy), aneurysm characteristics (size, shape, location and growth rate) as well as surgical team experience.
