The effect of intraarterial heparin flushing to autism symptoms when used to treat the concomitant cerebral venous thrombosis: a case series

Abstract

Introduction. There are still no definite therapeutic strategies for Autism Spectrum Disorder (ASD) other than behavioural interventions and few FDA approved behaviour control drugs. In this study, we found a co-existence medical condition of ASD & Cerebral Vein Thrombosis (CVT) in the paediatric population. Based on these findings, a new therapeutic approach, a catheter-directed anticoagulant therapy termed as IAHF (Intra Arterial Heparin Flushing) was performed on this population of patients.Methods. This paper aims to describe a series of 10 cases of IAHF procedure performed to treat CVT on children with ASD from 2018 through 2019 at Cerebrovascular Center RSPAD Gatot Soebroto Jakarta-Indonesia. The children diagnosed with ASD by the multidisciplinary team but also had CVT findings on their brain magnetic resonance imaging studies when performed as the series of comprehensive diagnostic examination. IAHF were conducted by delivering heparin through a modified DSA technique into the occluded vessels. Subject Autism status was assessed with the Childhood Autism Rating Scale (CARS) before and one month after IAHF procedures.Results. The measurement of CARS Score after IAHF shows a relatively positive result. Eight patients showed a decreased in total CARS Score after the procedure, while only two patients had no improvement. One subject shows a decrease of nine points, the most significant changes, and improved the status from moderate to mild autism.Conclusion. In children who have ASD and also accompanied by CVT findings in their imaging studies, IAHF treatment showed clinical improvement of the autism symptoms.Â

The Effect of the Intra-Arterial Heparin Flushing (IAHF) Procedure on Hearing Threshold in Sensorineural Hearing Loss Patients

“…Previous studies had investigated the clinical benefits of the IAHF procedure in ischemic stroke and autism ( 7 , 25 ). The results showed that the IAHF procedure increased cerebral blood flow 4 hours after the procedure by partial restoration of microcirculation ( 7 ).…”
