Vascular headache an traumatic brain injury

Abstract

In a medical emergency, the most urgent patients at significant risk of death are those witha cerebrovascular accident and those with traumatic brain injury. Many are admitted withdiminished conscience status (coma) and focal neurological deficits. In the evaluation ofthese patients, neuroimaging is indispensable in order to identify the type of lesion andthe location of the brain where it is located.In the case of stroke, we can subdivide it into hemorrhagic and ischemic. Among hemorrhagic hemorrhages, we can mention (1) spontaneous intracerebral hematomasand (2) hemorrhages due to rupture of an intracranial aneurysm, with subarachnoidhemorrhage leading.Patients with head trauma are critical; even those who arrive at the hospital alert andoriented can decrease their level of consciousness in a few hours due to an intracranialhematoma, edema, or cerebral contusion.Thus, the availability of performing neuroimaging evaluations, using computed tomography and magnetic resonance imaging, or even digital angiography, is vital for continuoussupervision of this type of patient. The exams often require repetition several times due tothe rate of evolution of vascular lesions and after head trauma.A warning sign in these types of patients is headache. In the intracranial aneurysmal rupture, we classically have the thunderclap headache, an explosive, sudden pain mentionedas the worst pain the individual has suffered in his or her life. The pericranium and someintracranial structures are sensitive to nociceptive stimuli, such as the dura mater, largearteries, and venous sinuses. The brain is relatively insensitive to painful stimuli.This narrative review aims to inform the importance of neuroimaging assessment of patients with stroke and traumatic brain injury in an emergency department. In conclusion,a neuroimaging evaluation is paramount in addition to a neurological and physicalexamination of the critically ill patient with cerebrovascular disease or who has suffereda traumatic brain injury
