RESUMO
Background Post dural puncture headache (PDPH) is an iatrogenic cause of patient morbidity in pain management after spinal or epidural anaesthesia, as well as after diagnostic lumbar puncture. Most patients respond to conservative treatment or to epidural blood patch, yet limited options for effective treatment are available for patients who fail these treatments or present with theoretical contraindication. Case report We present a case of a patient with previously diagnosed human immunodeficiency virus and hepatitis C, who presented with signs of PDPH, which placed him at a theoretical risk of meningeal seeding of the virus during the blood patching procedure. Conclusion We successfully treated the post dural puncture headache and avoided the risk of viral seeding of the meninges by using a fibrin sealant.
