Sir,We report the case of a 22-year-old man, weighing 53 kg, with a probable diagnosis of Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL), made by a neurologist who was scheduled for a brain biopsy for the confirmation of diagnosis. Earlier, he presented in the neurology outpatient department with a history of seizures since 4 years, imbalance while walking, change in behavior and personality, and forgetfulness since 2 years, as well as change in speech since 6 months. His history was significant for delayed mental milestones and normal motor mile stones. Neurological examination was significant for increased muscle tone in all limbs, exaggerated deep tendon reflexes, and dorsiflexed plantar response. Magnetic resonance imaging of the brain revealed bilateral cerebellar and cerebral atrophic changes, with bilateral cerebral white matter hyperintensities.We reviewed anesthetic literature for the management of CADASIL-type arteriopathy. An isolated report by Dieu and Veyckemans[1] described anesthetic management in a 30-year-old female patient with CADASIL who underwent laparoscopy. Our patient received intramuscular glycopyrrolate 0.2 mg as premedication one hour prior to surgery. General anesthesia was induced with propofol 80 mg and fentanyl 100 μg intravenously. Tracheal intubation was facilitated with rocuronium 1 mg/kg. Anesthesia was maintained with isoflurane and nitrous oxide in oxygen. Intraoperatively, the mean blood pressure was kept around 80 mm Hg and normocapnia was maintained. Intraoperative course was uneventful and the trachea was extubated at the end of surgery after reversal of the neuromuscular block. A week later, the brain biopsy report confirmed the diagnosis.The CADASIL syndrome is a rare inherited neurological condition resulting from non-atherosclerotic and non-amyloidosic microangiopathy. The clinical features of this syndrome include migraine, cognitive problems, seizures, psychiatric problems, and dementia accompanied by difficulty in walking, urinary incontinence, and pseudobulbar syndromes. The anesthetic considerations are similar to patients with cerebrovascular disease, which include maintenance of normocapnia and mean arterial blood pressure within the autoregulation range. Considering altered cerebral physiology in patients with CADASIL syndrome, Dieu and Veyckemans[1] suggest use of isoflurane for maintenance of anesthesia, norepinephrine for hypotension, and nimodipine for hypertensive episodes. Our patient had an uneventful intraoperative and postoperative course, thereby suggesting appropriate anesthetic management.
