Subdural Abnormal Communicating Vessel in Chronic Subdural Hematoma

Traditionally, lacerations of bridging vessels were surmised to cause chronic subdural hematoma (CSDH), although neither observation studies nor medical research was able to testify this. Nowadays, an inflammatory process is known to take place in the development of CSDH. Of note, post-traumatic angiogenesis at its early stage also features inflammation with immune cell infiltration. The authors found a patient suffering from CSDH with unusual angiogenesis between dura and pia matters. The observation of dura-and-pia angiogenesis may be a piece of evidence to underline compensatory reaction of central nervous system to offset the negative effects produced by CSDH, and points out to a possible approach of bolstering angiogenesis to manage ischemic diseases in cerebral hemispheres.
