Patients with cerebral hemorrhage are generally contraindicated to travel by airplane during the acute period, and should be cautious to travel by airplane during the recovery period. Because the pathogenesis of cerebral hemorrhage is mainly due to the thin diameter of small intracranial blood vessels and arterioles, and in the case of long-term hypertension, the walls of small arterioles form glassy or fibrous degeneration, and local degenerative necrosis and inflammatory reaction occurs, forming cornu aneurysms. In the case of sudden changes in intracranial blood pressure, sudden rupture can cause bleeding. Therefore, when traveling by airplane, especially during takeoff and landing, acceleration and deceleration, the patient’s own intracranial pressure changes, which can easily cause sudden rupture of small intracranial blood vessels and endanger life, so patients with cerebral hemorrhage should not travel by airplane as much as possible.
