Chronic ossified extradural hematoma on the opposite side of the ventriculoperitoneal shunt procedure: A rare case report

Acute Epidural Hematoma after Ventriculoperitoneal Shunt Insertion: a Case Report

“…Another theory state that what has led to the shrinkage and thus segregation of the dura from the skull regards excessive coagulation of the dura at the burr hole prior to incision. Valveregulated shunts, however, diminish subdural collections following drainage, so do the same in cases of epidural hematoma (7). The incidence of epidural hematoma after ventricular shunt operation was 5.6% in adults and 0% in children before the advent of valve-regulated shunt (1).…”

“…A drastic decline in the ICP may well cause subdural collection following ventricular drainage, particularly following chronic hydrocephalus in those with craniocerebral discrepancy (6). Nevertheless, epidural hematomas rarely occur in such cases owing to the adherence of the dura to the skull (7). Even so, it occurs in younger patients (1-3,6-8) at anatomical sites in which pathology is more likely to be detected (parietal and frontal regions) (4).…”

“…This can often be seen in infants whose dura matter is loosely attached to the inner cranium (9). Detachment of dura matter from inner table of the skull may initially cause dural and diploic veins bleeding, thereby widening the gap between the dura matter and bony arterial cannels, which, in turn, causes dural arteries tearing (7). Another theory state that what has led to the shrinkage and thus segregation of the dura from the skull regards excessive coagulation of the dura at the burr hole prior to incision.…”

Burr hole site acute extradural hematoma after ventriculoperitoneal shunt surgery: a rare case report and its pathogenesis

“…The largest case series of epidural hematoma after ventricular decompression, from Odake and Matsumoto [9], includes not only ventriculoperitoneal shunt but also other procedures for draining cerebrospinal fluid: ventricular puncture, ventriculography, ventriculoatrial shunts leading to development of EDH after the procedure.…”

Chronic calcified extradural and subdural hematoma following a ventriculoperitoneal shunt placement

“…It occurs more commonly in the younger age group due to the presence of lax adhesions between the dura and the calvarium. [2] To the best of the authors' knowledge, the simultaneous association of a CEDH and CSDH in a patient has not been reported till date. The pathogenic mechanisms responsible for the occurrence of calcification remain unclear.…”
