The cerebrovascular time constant (τ) theoretically estimates how fast the cerebral arterial bed is filled by blood volume after a sudden change in arterial blood pressure during one cardiac cycle. The aim of this study was to assess the time constant of the cerebral arterial bed in patients with traumatic brain injury (TBI) with and without intracranial hematomas (IH). We examined 116 patients with severe TBI (mean 35 ± 15 years, 61 men, 55 women). The first group included 58 patients without IH and the second group included 58 patients with epidural (7), subdural (48), and multiple (3) hematomas...

Cerebral venous sinus thrombosis (CVST) following a closed head injury in pediatric patients is a rare condition, and an early spontaneous recanalization of this condition is extremely rare. A 10-year-old boy was admitted with a mild, intermittent headache and nausea five days after a bicycle accident. The brain computed tomography showed an epidural hematoma at the right occipital area with pneumocephalus due to a fracture of the occipital skull bone. The brain magnetic resonance imaging and the magnetic resonance venography demonstrated a flow signal loss from the right sigmoid sinus to the right jugular vein...

BACKGROUND: Posterior fossa dural venous sinus thrombus is a well-described complication of head trauma, especially when fracture crosses the dural sinus grooves or in association with epidural hemorrhage. We have found that post-traumatic posterior fossa epidural hematoma compressing a dural venous sinus can mimic dural venous thrombus. OBJECTIVE: To discuss the CT and MRI findings of posterior fossa epidural hemorrhages simulating sinus thrombosis, to make radiologists aware of this important imaging pitfall...

The objective of this study was to determine whether the type of intracranial traumatic lesions, the number of simultaneous traumatic lesions, and the occurrence of skull and facial bone fractures have an influence on S100 calcium binding protein B (S100B) serum levels. Patients with blunt traumatic brain injury were prospectively enrolled into this cohort study over a period of 13 months. Venous blood samples were obtained prior to emergency cranial CT scan in all patients within 3 h after injury. The patients were then assigned into six groups: 1) concussion, 2) epidural hematoma, 3) subdural hematoma, 4) subarachnoid hemorrhage, 5) brain contusions, and 6) brain edema...

BACKGROUND: Intracranial subdural hematoma is an exceptionally rare but life-threating complication of epidural and spinal anesthesia. The diagnosis is rather difficult because the initial symptoms mimic post-dural puncture headache. CASE REPORT: A 33-year-old primipara was admitted to the hospital at 38 weeks gestation for a cesarean section due to premature rupture of membranes and meconium stained amniotic fluid. During the procedure a single puncture between L2 and L3 vertebrae was made with the use of a 26-gauge, pencil-point needle...

Spontaneous intracranial hypotension typically results from spontaneous cerebrospinal fluid (CSF) leak, often at spine level and only rarely from skull base. Once considered rare, it is now diagnosed far more commonly than before and is recognized as an important cause of headaches. CSF leak leads to loss of CSF volume. Considering that the skull is a rigid noncollapsible container, loss of CSF volume is typically compensated by subdural fluid collections and by increase in intracranial venous blood which, in turn, causes pachymeningeal thickening, enlarged pituitary, and engorgement of cerebral venous sinuses on magnetic resonance imaging (MRI)...

INTRODUCTION: Cerebral venous sinus thrombosis (CVST) following a blunt head trauma is a rare condition, described in the literature along with the lack of consensus regarding diagnosis and management. We present a case of a pediatric patient with a blunt head injury and epidural hematoma, who developed dural sinus and internal jugular vein thrombosis with fatal outcome. DISCUSSION: Most of reports show good outcome and recovery, but CVST might be related to poor recovery and even lead to death...

We report a case of cranial subdural hematoma with intracranial hypotension. A 34-year-old woman had laparoscopic ovarial cysterectomy under general anesthesia combined with epidural anesthesia. Two days later, she developed a severe headache and nausea. She underwent cranial magnetic resonance imaging (MRI) scanning, and was diagnosed with cranial subdural hematoma with intracranial hypotension. The patient had had no anticoagulant therapy before the surgery. She was managed conservatively with bed rest and additional intravenous infusion...

A 48-year-old woman suffered head trauma and presented with an acute epidural hematoma with a linear fracture of the right temporal bone across the middle meningeal groove. Initial angiography demonstrated no vascular abnormalities. Eight months later, she again suffered head trauma and computed tomography demonstrated traumatic subarachnoid hemorrhage. Right external carotid angiography revealed a middle meningeal arteriovenous fistula (AVF) which drained into the superficial sylvian veins via the sphenoparietal sinus...

We describe a case of 36-year-old man who presented with a subacute headache preceded by a 1-month history of posterior neck pain without trauma history. Head and neck magnetic resonance imaging (MRI) studies disclosed bilateral supratentorial subdural and retroclival extradural hematomas associated with marked cervical epidural venous engorgement. Cerebral and spinal angiography disclosed no abnormalities except dilated cervical epidural veins. We performed serial follow-up MRI studied to monitor his condition...

Venous sinus thrombosis is a rare entity that usually arises secondary to underlying thrombophilia, neoplasm, head injury, or infection. Tympanic infection accounts for the majority of infectious etiologies, and the sigmoid sinus becomes the likely anatomical site of thrombosis. The authors report a case involving a child with recurrent otitis media who presented with an atraumatic epidural hematoma secondary to sigmoid sinus thrombosis. Intraoperative evaluation revealed epidural hemorrhage that originated from the venous sinus, with hemorrhagic products of varying ages...

OBJECTIVE: To determine the safety of early enoxaparin for venous thromboembolism (VTE) prophylaxis in patients with blunt traumatic brain injury (TBI). METHODS: Prospective observational study of patients with TBI who received enoxaparin within 48 hours after admission. Brain computed tomography (CT) scans were obtained at the time of admission, at 24 hours, and at variable intervals thereafter based on clinical course. Patients were excluded from the study for intracerebral contusions >/=2 cm, multiple contusions within one brain region, subdural or epidural hematomas >/=8 mm, increased size or number of lesions on follow-up CT, persistent intracranial pressure >20 mm Hg, or neurosurgeon or trauma surgeon reluctance to initiate early pharmacologic VTE prophylaxis...

OBJECTIVE: Spinal fluid drainage reduces paraplegia risk in thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysm repair. There has not been a comprehensive study of the risks of spinal fluid drainage and how these risks can be reduced. Here we report complications of spinal fluid drainage in patients undergoing TAA/TAAA repair. METHODS: The study comprised 648 patients who had TAA or TAAA repair from 1987 to 2008. Spinal drains were used in 486 patients. Spinal fluid pressure was measured continuously, except when draining fluid, and was reduced to <6 mm Hg during thoracic aortic occlusion and reperfusion...

INTRODUCTION: The purpose of this paper is to review the role of the neurologist in the management of cerebrovascular accidents (CVA) (insults resulting from a sudden obstruction or rupture of an intracranial vessel). This was accomplished by reviewing the literature (PubMed) under the heading of stroke and term neonate. DEVELOPMENT: CVA in full-term neonates are classified as hematomas and infarcts. Hematomas are classified according to: location, structure (arterial, venous, or sinus), type of malformation (aneurysm, venous malformation, and telangiectasia), and cause of the bleed (vessel wall rupture or hypo-coagulation)...
