    Immediate postoperative death due to hypothalamic injury following surgery for craniopharyngioma
    (JOURNAL OF CLINICAL NEUROSCIENCE, 2009) Bahuleyan, B; Menon, G; Nair, S
    Autonomic disturbances due to hypothalamic injury that result in postoperative death are rare complications following surgery for craniopharyngioma. We discuss the case of a child who died due to hypothalamic injury following radical excision of a multi-compartmental craniopharyngioma. Mechanisms and clinical manifestations of hypothalamic injury and ways to avoid this fatal complication are discussed. (C) 2008 Elsevier Ltd. All rights reserved.

    Utility of diffusion tensor imaging tractography in decision making for extratemporal resective epilepsy surgery
    (EPILEPSY RESEARCH, 2011) Radhakrishnan, A; James, JS; Kesavadas, C; Thomas, B; Bahuleyan, B; Abraham, M; Radhakrishnan, K
    Purpose: To assess the utility of diffusion tensor imaging tractography (DTIT) in decision making in patients considered for extratemporal resective epilepsy surgery. Methods: We subjected 49 patients with drug-resistant focal seizures due to lesions located in frontal, parietal and occipital lobes to DTIT to map the white matter fiber anatomy in relation to the planned resection zone, in addition to routine presurgical evaluation. We stratified our patients preoperatively into different grades of risk for anticipated neurological deficits as judged by the distance of the white matter tracts from the resection zones and functional cortical areas. Results: Thirty-seven patients underwent surgery; surgery was abandoned in 12 (24.5%) patients because of the high risk of postoperative neurological deficit. DTIT helped us to modify the surgical procedures in one-fourth of occipital, one-third of frontal, and two-thirds of parietal and multilobar resections. Overall, DTIT assisted us in surgical decision making in two-thirds of our patients. Conclusions: DTIT is a noninvasive imaging strategy that can be used effectively in planning resection of epileptogenic lesions at or close to eloquent cortical areas. DTIT helps in predicting postoperative neurological outcome and thereby assists in surgical decision making and in preoperative counseling of patients with extratemporal focal epilepsies.
