Vascular headache

Nancy E Epstein
Background: The risk of spinal cord injury (SCI) due to decreased cord perfusion following thoracic/thoracoabdominal aneurysm surgery (T/TL-AAA) and thoracic endovascular aneurysm repair (TEVAR) ranges up to 20%. For decades, therefore, many vascular surgeons have utilized cerebrospinal fluid drainage (CSFD) to decrease intraspinal pressure and increase blood flow to the spinal cord, thus reducing the risk of SCI/ischemia. Methods: Multiple studies previously recommend utilizing CSFD following T/TL-AAA/TEVAR surgery to treat SCI by increasing spinal cord blood flow...

Objective: Arteriovenous malformation (AVM) is the most common form of intracranial vascular malformations in adults. Intracranial pediatric AVMs are rare. AVM located in the vicinity of the brain stem in children are even more rare. Case report: This study reports a rare case of acute obstructive hydrocephalus following aqueductal stenosis caused by an unruptured grade IV perimesencephalic arteriovenous malformation. An 11-year-old boy admitted to the hospital with progressive headache, nausea and vomiting throughout a month...

Fibromuscular dyplasia (FMD) is an under-recognized non-atherosclerotic, non-inflammatory arteriopathy that occurs most commonly in middle-aged women, but may affect individuals of all age groups. FMD may result in stenosis, aneurysm, dissection, occlusion, or arterial tortuosity. Recently published data demonstrated a genetic association of FMD with a variant in the phosphatase and actin regulator 1 gene (PHACTR1), substantiating that the pathogenesis of this condition has genetic contribution. The renal and extracranial carotid and vertebral arteries are most often involved, although any arterial bed may be affected...

BACKGROUND: Spontaneous epidural hemorrhage (EDH) is a rare occurrence that may be caused by vascular anomalies, infections, coagulopathies, or tumors. Spontaneous EDH occurring in patients without specific underlying disease has been reported only as intraspinal lesion but has never been demonstrated in the intracranial area. This study presents a 19-year-old patient with repeated spontaneous intracranial EDH caused twice by hysterical crying. CASE DESCRIPTION: The patient had spontaneous left frontal EDH after hysterical crying...

Objective: The objective of this study is to determine whether structural features of the vertebrobasilar arterial system are related to migraine. Background: Alterations in cerebral vascular structure and function have been associated with migraine, possibly mediated by hypoperfusion and/or endothelial dysfunction triggering cortical spreading depression. Vessel tortuosity, in particular, has been associated with both altered hemodynamics and endothelial function...

Cerebral amyloid angiopathy (CAA) is most commonly recognized by β-amyloid deposition in the small and medium sized vessels of the brain. The 71-year-old female presented with a sudden onset of vertigo and headache. By native computer tomography (CT) examination we found cerebral atrophy and the sign of chronic vascular injury. The complaints of the patient worsened, thus magnetic resonance imaging (MRI) was performed. The MRI scan revealed a bleeding transformation of an ischemic lesion in the right occipital region...

Pituitary adenylate cyclase-activating peptide (PACAP) is a neuropeptide implicated in a wide range of functions, such as nociception and in primary headaches. Regarding its localization, PACAP has been observed in the sensory trigeminal ganglion (TG), in the parasympathetic sphenopalatine (SPG) and otic ganglia (OTG), and in the brainstem trigeminocervical complex. Immunohistochemistry has shown PACAP-38 in numerous cell bodies of SPG/OTG, co-stored with vasoactive intestinal peptide (VIP), nitric oxide synthase (NOS) and, to a minor degree, with choline acetyltransferase...

INTRODUCTION: Moyamoya disease (MMD) is an occlusive cerebrovascular disease characterized by progressive stenosis or occlusion in the terminal portion of the bilateral internal carotid arteries, affecting both children and adults. AIM: To conduct a review and update on MMD from a clinical, neuroradiological, neuropsychological and genetic perspective. DEVELOPMENT: In this pathology, which occurs with ischemia or cerebral hemorrhage, an unusual compensatory vascular network (moyamoya vessels) develops at the base of the brain in the form of collateral channels...

PURPOSE OF REVIEW: Menopause is a life-changing event in numerous ways. Many women with migraine hold hope that the transition to the climacteric state will coincide with a cessation or improvement of migraine. This assumption is based mainly on common lay perceptions as well as assertions from many in the healthcare community. Unfortunately, evidence suggests this is far from the rule. Many women turn to a general practitioner or a headache specialist for prognosis and management. A natural instinct is to manipulate the offending agent, but in some cases, this approach backfires, or the concern for adverse events outweighs the desire for a therapeutic trial, and other strategies must be pursued...

BACKGROUND: Familial Mediterranean fever is an autoinflammatory disease of unknown etiology, characterized clinically by recurrent attacks of sudden-onset fever with arthralgia and/or thoracoabdominal pain and pathogenetically by autosomal recessive inheritance due to a mutation in the MEFV gene. Behçet's disease is an inflammatory disease characterized by recurrent oral and genital aphthous ulcerations, uveitis, and skin lesions. Preliminarily, our literature review suggested that patients with familial Mediterranean fever who also have Behçet's disease have only a single mutated familial Mediterranean fever gene...

Intracranial chondrosarcoma is a very rare malignant tumor of the central nervous system, and is difficult to preoperatively distinguish from other tumors using conventional imaging techniques. Here, we report the case of a 24-year-old woman who presented with mild headache due to chondrosarcoma in the frontal lobe. Preoperative conventional images showed findings typical of an oligodendroglial tumor. However, high apparent diffusion coefficient (ADC) value and extreme hypoperfusion on arterial spin labeling (ASL) were inconsistent with oligodendroglial tumor characteristics...

AIM: Idiopathic intracranial hypertension (IIH) is characterized by symptoms indicative of increased intracranial pressure (ICP), such as headache and visual impairment. We have previously reported that brain biopsies from IIH patients show patchy astrogliosis and increased expression of the water channel aquaporin-4 (AQP4) at perivascular astrocytic endfeet. METHODS: The present study was undertaken to investigate for ultrastructural changes of the cerebral capillaries in individuals with IIH...

INTRODUCTION: Hemangioblastoma (HB) is a benign vascular tumor that accounts for about 2% of intracranial neoplasms. HB of the cavernous sinus (CS) is extremely rare. Only one report was found in the literature. PRESENTATION OF CASE: We present a 29-year-old female with progressive headache and she had right ptosis and right mild oculomotor nerve palsy. The brain Magnetic Resonance Imaging (MRI) revealed a right extra-axial 4 × 4 cm in right CS position. The patient was operated upon microscopically via sub-temporal approach through a right temporal craniotomy...

PURPOSE: Isolated basilar artery dissection (BAD) is a rare cause of ischemic stroke. Since the clinical presentations and imaging findings could be non-specific and subtle, the diagnosis may be difficult. Here, we presented four cases of isolated BAD with acute ischemic stroke. CASE REPORT: Four patients (age, 22 to 57 years) experienced acute onset of hemiparesis and/or vertigo with half of them having initial headache. Acute infarct was noted at pons or thalamus...

BACKGROUND: To review the role of PACAP38 in human models of primary headaches, discuss possible mechanisms of PACAP38-induced migraine, and outline future directions. DISCUSSION: Experimental studies have established PACAP38 as a potent pharmacological "trigger" molecule of migraine-like attacks. These studies have also revealed a heterogeneous PACAP38 migraine response in migraine without aura patients. In addition, findings from brain imaging studies have demonstrated neuronal and vascular changes in migraine patients both ictally and interictally after PACAP38 infusion...

OBJECTIVES: Crimean-Congo Hemorrhagic Fever (CCHF) is a fatal, tick-borne disease. The classic clinical presentation of CCHF is characterized by sudden onset of high fever, chills, and severe headache. There are no previous reports on the characteristics of headaches caused by CCHF. Therefore, we investigated the relationship between CCHF-induced headache and the clinical course of the disease. METHODS: We included 60 patients with headache diagnosed with CCHF; they were divided into two groups: group 1 included patients with hospital stay <7 days and group 2 included patients with hospital stay >7 days...

Spreading depression (SD) is a neurophysiological phenomenon characterized by abrupt changes in intracellular ion gradients and sustained depolarization of neurons. It leads to loss of electrical activity, changes in the synaptic architecture, and an altered vascular response. Although SD is often described as a unique phenomenon with homogeneous characteristics, it may be strongly affected by the particular triggering event and by genetic background. Furthermore, SD may contribute differently to the pathogenesis of widely heterogeneous clinical conditions...

OBJECTIVE: To describe acute headache diagnoses in women presenting emergently in the postpartum period and to determine which factors may be associated with secondary vs primary headache. BACKGROUND: Hormonal, vascular, and procedural factors elevate the risk for both secondary and primary headache disorders in the postpartum period. Differentiating between these can be a diagnostic challenge, particularly among the most severe patients referred for urgent neurological consultation...

PURPOSE OF REVIEW: Migraine is an extremely incapacitating collection of neurological symptoms that usually includes a severe, throbbing, recurring pain on one side of the head. The World Health Organization ranks migraine as the third most prevalent disease and the seventh commonest primary pain condition in the world. Trigeminovascular-mediated central sensitization has been implicated in the development of migraine symptoms including pain following light touch. This review explores the activation and sensitization of the brain systems that have emerged from recent studies and that contribute to migraine...

This is the case of a previously healthy 48 year-old male whom presented with mild confusion, low-grade headache, and left sided weakness. Computed tomography of the head revealed a large acute right frontal lobe intracranial hemorrhage (ICH) and intraventricular extension, with normal vascular imaging. Initial laboratory testing was inconsequential. The patient required emergent evacuation, with pathology revealing only elements of a hematoma. Further laboratory testing and bone marrow biopsy results confirmed the diagnosis of plasma cell myeloma...
