Abstract

VALENCIA-CALDERON, C et al. Neuronavigation In Pre Surgical Planning And Surgery Of Refractory Epilepsy. Rev Ecuat Neurol [online]. 2018, vol.27, n.2, pp.31-38. ISSN 2631-2581.

Introduction:

Epilepsy is one of the more frequent neurologic disorders, with an incidence of 50/100,000/year and prevalence between 0.5 and 2% worldwide. A third of these patients suffer focal epilepsy due to epileptogenic lesions evident by Neuroimaging new techniques. Epilepsy surgery is the only treatment that can cure refractory epilepsy. Its goal is to remove the epileptogenic lesion with preservation of eloquent areas, and in this case both surgical experience and neuroimaging technology play a pivotal role.

Objective:

To demonstrate utility of neuronavigation in presurgical planning and surgery of refractory epilepsy.

Method:

Descriptive, cross sectional and analytic study of 47 performed surgeries (12 resective, 12 palliative and 3 diagnostic) in patients with refractory epilepsy with an average age of 9.93 years (SD 4.1). In 27 patients (57.44%) neuronavigation was used. In patients operated with assistance of neuronavigation, surgical time diminished in 47.17 minutes (p=0.022), hemorrhage in 111.41 ml (p=0.011) and days of hospitalization in 6.68 days (p=0.005) comparing with group without neuronavigation. Complications in the group with neuronavigation were 29.63% compared with 65% in the group without it. (P=0,034).

Conclusions:

In this study, using neuronavigation in planning and performing surgery in reducing the amount of blood loss, surgical time, days of hospitalization and post surgical complications.
