Cerebral Vasospasm in Patients With Severe Traumatic Brain Injury
نویسندگان
چکیده
Methods The study included 43 patients with isolated and combined sTBI and Glasgow Coma Scale on admission 8 or less (age 32.4 ± 10.8 years, men/ women 36/7). Severe brain contusion was diagnosed in all patients. Emergency surgery was required in 20 patients. All patients received decompressive craniotomy with intracranial hematoma or contusion foci removal. Transcranial duplex investigation was performed every day from 2 till 11 day after admission. We measure blood flow velocity, Lindegaard index, pulsatility index, overshoot ratio. Cerebral vasospasm was diagnosed in case of systolic blood flow velocity (Vs) in the middle cerebral artery 120 cm/sec or more with Lindegaard index 3 or more.

Severe cerebral vasospasm after traumatic brain injury.
Severe traumatic brain injury is associated with both acute and delayed neuro- logical injury. Cerebral vasospasm is commonly associated with delayed neurological decline in aneurysmal subarachnoid hemorrhage patients. However, the role played by vasospasm in traumatic brain injury is less clear. Vasospasm occurs earlier, for a shorter duration, and often without significant neurological conseq...

While a wide array of pathological changes occur in cerebral arteries following subarachnoid hemorrhage (SAH), the most consistent is endothelial damage. Since the endothelium normally modulates reflexes that influence vascular tone, any damage to it may represent a significant contributor to cerebral vasospasm following SAH. This experimental study investigates the correlation between end...

متن کاملThe use of intravenous Milrinone to treat cerebral vasospasm following traumatic subarachnoid hemorrhage
INTRODUCTION Traumatic subarachnoid hemorrhage (SAH) is a common intracranial lesion after traumatic brain injury (TBI). As in aneurysmal SAH, cerebral vasospasm is a common cause of secondary brain injury and is associated with the thickness of traumatic SAH. Unfortunately, there is limited literature on an effective treatment of this entity. The vasodilatory and inotropic agent, Milrinone, ha...
