Sarat title: Epilepsy surgery in COVID times—a unique conundrum date: 2021-04-10 journal: Childs Nerv Syst DOI: 10.1007/s00381-021-05048-4 sha: ac2813252697f48101b21ff4045058553598779d doc_id: 819452 cord_uid: t57zvcje The COVID-19 pandemic has forced hospitals to prioritize admissions. Epilepsy surgeries have been postponed at most centers. As the pandemic continues with no definite end in sight in the near future, the question arises until when such patients should be denied appropriate treatment. A 12-year-old child with left-sided Rasmussen’s encephalitis with drug refractory epilepsy (DRE) presented at the height of the pandemic, with worsening of seizure frequency from 4–5/day to 20/day, with new-onset epilepsia partialis continua. She demonstrated features of progressive cognitive decline. The pros and cons of operating during the pandemic were discussed with the parents by a multidisciplinary team. She underwent endoscopic left hemispherotomy. Postoperatively she became seizure free but developed hospital-acquired mild COVID infection for which she was treated accordingly. Chosen cases of severe DRE, as the one illustrated above, who are deemed to benefit from surgery by a multidisciplinary team of physicians, should be re-categorized into the most severe class of patients and scheduled for surgery as soon as possible. The risk benefit ratio of the seizures being mitigated by surgery on one hand and possibility of acquiring COVID infection during hospital stay has to be balanced and a decision made accordingly. Surgical admissions were prioritized during the COVID-19 pandemic [9, 12, 15, 17, 22] . Barring acute life-threatening conditions, most routine surgical cases were recommended to be postponed. One such group of patients were those suffering from drug refractory epilepsy (DRE) [9, 12, 15, 17, 22] . Epilepsy is a chronic condition, but a subset of patients in this group have multiple seizures daily [14] . Risks of continuing seizures include unexpected injuries, epileptic encephalopathy, status epilepticus, side effects of anti-epileptic drugs (AEDs), and the cumulative risk of sudden unexpected death in epilepsy patients [8, 10, 14] . This assumes more importance in a child suffering with daily seizures, especially when evaluation reveals a condition which may be amenable to surgical correction [21] . Surgery has not only been shown to be treatment of choice in pediatric patients suffering from DRE, but it has also shown to greatly improve cognitive outcomes [4, 11] . Hence, it has been recommended for all patients with DRE to undergo early evaluation for possible epilepsy surgery [20] . As the COVID-19 pandemic continues, the question arises until when such patients should be denied appropriate treatment. We present a case which illustrates this dilemma which has been faced by epilepsy care givers in their day-to-day practice over the past few months. & Clinical presentation: A 12-year girl had been having focal motor seizures involving the right half of the body with progressive hemiparesis since the past 4 years. On the basis of extensive evaluation, she had been diagnosed with Rasmussen's encephalitis with DRE and was planned to undergo left hemispherotomy, which was postponed because of the restrictions imposed due to COVID-19. During the pandemic, despite receiving five AEDs in appropriate doses, her seizure frequency worsened, and she developed epilepsia partialis continua (EPCs) involving the right hand. She became severely incapacitated and completely dependent on her parents to carry out her daily activities. & Preoperative investigations: The child was admitted, and a video electroencephalogram (VEEG) and MRI were repeated (Figs. 1 and 2). Ancillary investigations had been done before the pandemic (Fig. 3) . Neuropsychological assessment revealed a co-operative and communicative child with mild impairment of intellectual ability, mild memory impairment, and occasional behavioral abnormalities in the form of anger outbursts. & Decision regarding surgical intervention: The case was discussed in a multi-disciplinary meeting. Considering the rapidly deteriorating general condition of the patient, it was decided to go ahead with immediate surgery. Her parents were counseled regarding the special protocols in place to mitigate the risk of iatrogenic COVID infection, namely, pre-admission COVID testing, restriction upon the number of hospital visitors, wearing masks and following hand hygiene protocols, a repeat preoperative COVID test, and the risk of postoperative infection. & Surgery and postoperative course: The patient underwent endoscopic-assisted left hemispherotomy [6, 7] , under all recommended precautions (Fig. 4a, b) . She had an expected worsening of hemiparesis. She had no postoperative seizures. On day 12 after surgery, she developed diarrhea. A repeat COVID testing was conducted for which she As per protocol, she was immediately transferred to the designated COVID hospital of our institute. She maintained oxygen saturation more than 95% on room air and respiratory rate remained normal, she had no fever, and inflammatory markers and chest radiographs were also within the normal limits (Fig. 4c) . She was categorized as having mild COVID infection and kept under observation. All her primary high-risk contacts tested negative, except for her physiotherapist who developed fever and tested positive for the virus 3 days later. At 3 months of follow-up, patient has remained seizure free and is able to walk with support. Epilepsy care services were severely affected across the board by the COVID-19 pandemic [1, 2, 13, 19] . However, the needs of the epilepsy patient community remained unchanged or even worsened by the imposition of lockdown and movement restrictions in several countries [1, 2, 13, 19] . Therefore, there is an urgent need to identify the patients with DRE most at risk and prioritize their management. Among this subset of patients, those who can potentially benefit from undergoing epilepsy surgery should be identified and fast forwarded for appropriate management. Our patient was at the brink of potentially irreversible deterioration in cognition, quality of life, as well as the risk posed due to high frequency of seizures. Rasmussen's encephalitis is a progressive disease, and surgery in the form of functional hemispherotomy is the only definitive treatment, following which seizure-free outcomes of 70-80% have been consistently demonstrated [5] . Such a high-documented seizure freedom rate was one of the factors which gave us confidence to go ahead with surgery. The risk benefit ratio of the seizures being mitigated by surgery on one hand and possibility of acquiring COVID infection during hospital stay has to be balanced. Fear of the risk of seizure worsening as a potential effect of COVID infection has remained largely unfounded. In a study from three tertiary care epilepsy hospitals from Spain and Italy, among the 5700 patients with epilepsy, only 14 tested positive for the virus. Further, there was no observed detrimental effect of the infection on the course of epilepsy [13] . Similarly, majority of the [2] . Rather than a direct effect of the viral infection, this worsening has been postulated to be due to the reduced seizure threshold associated with fever, increased stress levels, reduced sleep, and decreased drug compliance [18, 23] . As the pandemic has progressed, a greater understanding of the disease pathophysiology and infection prevention strategies has now been obtained [16] . In an editorial published in the Journal of Neurosurgery at the start of this pandemic, it was suggested that every surgeon who confronts a possible surgical case in this time should ask herself/himself, "Is this patient likely to be able to safely wait for things to return to normal without incurring further neurological deficit and/or progression of disease to a point where it is less amenable to treatment?" If the answer to the above question was negative, it was recommended to advocate as strongly as possible to go ahead with surgery for such a patient [3] . Chosen cases of severe DRE, as the one illustrated above, should be re-categorized into the most severe class of patients and scheduled for surgery as soon as possible.
