title: Bilateral subdural hematomas in an adult with hereditary factor VII deficiency: A complication of sit-ups and inversion?
abstract: A 57-year-old man of northern Italian and Polish descent with a late-onset, mild form of hereditary factor VII deficiency developed bilateral intracranial subdural hematomas after performing sit-ups while he was in a head-down position on an inversion table. The pertinence of the Valsalva maneuver and increased intracranial venous and intraocular pressure associated with sit-ups and other exercises in the causation of subdural hematomas and other types of intracranial and ocular hemorrhage are discussed in this study.
