Nakajima M, Pearce LA, Ohara N, Field TS, Bazan C, Anderson DC, et al. It is often associated with the vascular compression of the trigeminal nerve root entry zone, and also related to the superior cerebellar artery or anterior inferior cerebellar artery (2). Intracranial arterial dolichoectasia and its relation with atherosclerosis and stroke subtype. The main focus of this discussion will be dolichoectasia of the internal carotid artery (ICA) and other surrounding vessels causing compression of the anterior visual pathways. The vertebral artery has been considered abnormal if a deviation of >10 mm from the shortest expected course or a length >23.5 mm exists (31). It has a complex pathogenesis, which needs further investigation. Neurosurgery (1985) 17(5):797–800. Rahman EA, Trobe JD, Gebarski SS. However, most cases are sporadic and associated with traditional vascular risk factors including advanced age, male gender, and arterial hypertension.

For these reasons, VBD and BADE have been preferentially studied and better defined in the literature. Vertebrobasilar dolichoectasia is a condition where the vertebral arteries are dilated, elongated and distorted, causing significant deterioration of tunica intima. Am J Ophthalmol (2004) 137(2):365–7. Its neurological symptoms and signs are highly variable. His symptoms started a year earlier while on vacation (biking) in Tuscany, Italy with his sister. His sister recalled he appeared more quiet than usual. Smoker and colleagues (1) recommended a cutoff of 4.5 mm diameter at the level of the mid pons to define BA ectasis based on their analysis of 126 CT scans of individuals without underlying brain injury (age ranging from 4 to 85 years). Dolichoectasia diagnostic methods in a multi-ethnic, stroke-free cohort: results from the northern Manhattan study. Hydrocephalus as a complication of vertebrobasilar dolichoectasia is rare. Giant serpentine aneurysm of vertebrobasilar artery mimicking dolichoectasia – an unusual complication of pediatric AIDS. Background: Dolichoectasia is a rare disorder of the cerebral vasculature consisting of vascular elongation, widening, and tortuosity, usually involving the vertebral and basilar arteries. Case reports: We report three cases of … Results from two case-control studies found that individuals with stroke and IADE had a higher prevalence of lacunar infarctions (36–42%) compared to those without IADE (17–19%) (7, 41). Guirgis MF, Lam BL, Falcone SF. Vertebrobasilar dolichoectasia is a formidable structural entity afflicting the posterior circulation, which is generally thought to cause symptoms as a result of either compression of the adjacent brain stem and/or cranial nerves or ischemic events caused by thrombosis and perforator occlusion. doi:10.1016/0022-510X(69)90006-9, 75. The clinical picture of ectasia of the intracerebral arteries. J Am Coll Cardiol (2002) 40(1):43–8. Comment. Diagnostic criteria and prognosis studies of IADE are based on basilar artery diameter, which is a good quantitative marker for the severity of the disease. Ischemia, cranial nerve compression, vertigo (as in this case), sialorrhea, dysphagia, tinnitus, imbalance, and others symptoms may be seen in the brainstem compression by vascular structures such as vertebrobasilar dolichoectasia 1. Atherosclerotic aneurysm is a misnomer, as arterial dolichoectasia is a distinct arteriopathy from atherosclerosis. Disclaimer, National Library of Medicine Cerebral microbleeds, another imaging marker of SVD, were more prevalent in stroke patients with IADE than in those without (39).

In one of these studies, small artery occlusion was the only stroke mechanism associated with IADE (OR 2.89; C.I. Others present with nonlocalizing symptoms of headaches, seizures, and dementia ( 1, 3, 7 ). Different terms such as mega-artery, mega dolichoartery, fusiform aneurysm, cirsoid aneurysm, serpentiform aneurysm, atherosclerotic aneurysm, and dilatative arteriopathy have been used to describe the abnormal distention and elongation of intracranial arteries (2, 3, 12, 22, 23).

The symptoms of vertebrobasilar circulatory disorders vary. Dolichoectasia is a condition in arteries characterized by weakening of its wall leading to a dilated, elongated, and/or tortuous vessel. VBD is a rare dilative arteriopathy where the intracranial vertebral and/or basilar arteries become dilated, elongated and tortuous resulting in pulsatile compression of nearby structures. Sacks JG, Lindenburg R. Dolicho-ectatic intracranial arteries: symptomatology and pathogenesis of arterial elongation and distention. Increased MMPs activity is linked to the pathogenesis of several central nervous system diseases including multiple sclerosis, Alzheimer’s disease, and acute stroke (64, 65). Would you like email updates of new search results? However, they lack validation across studies. Conversely, abnormal upregulation of MMPs at the cellular level promote cytotoxicity and central nervous system inflammation by degradation of basal lamina proteins leading to disruption of the blood–brain barrier and breakdown of myelin (61–63).

J Korean Neurosurg Soc (2008) 44(3):116–23. Intracranial arterial dolichoectasia implies a spectrum that includes normal variations in the diameter and tortuosity of the cerebral vasculature as well as gigantic aneurysmal dilations with a high risk of fatal complications. doi:10.1016/0090-3019(87)90251-5, 68. In young subjects and in those without vascular risk factors, primary predisposing conditions should be considered (i.e., Marfan’s, Fabry’s, adult-onset Pompe’s disease, etc.).

Sho E, Sho M, Singh TM, Nanjo H, Komatsu M, Xu C, et al. Fully revised and updated, the Handbook serves as a practical guide to endovascular methods and as a concise reference for neurovascular anatomy and published data about cerebrovascular disease from a neurointerventionalist’s perspective. Pico and collaborators (3) proposed IADE as a more accurate term to avoid overlooking for anterior circulation pathology. doi:10.1161/01.STR.0000259708.05806.76, 22.

To better define the clinical significance of vertebrobasilar dolichoectasia, the clinical signs and symptoms and basilar artery parameters of diameter, height, and transverse position were evaluated in two groups of symptomatic patients. 27 (12):3503-4, 2018. Intracranial arterial dolichoectasia is a condition characterized by enlargement, tortuosity, or elongation of major arteries at the base of the brain. • Fusiform and dolichoectatic aneurysms can present with ischemic strokes, intracranial hemorrhage, or symptoms related to compression of cranial nerves or brain structures, but they are also often asymptomatic and detected incidentally.

Stroke and dolichoectatic intracranial arteries. dolichoectasia and EEC has not yet been outlined in a formal literature review or even case series, so this article aims to explore a series of case reports to better highlight the various etiologies, symptoms, and presentations of EEC as they relate to dolichoectasia. *Correspondence: Victor J. Del Brutto, victor.delbruttoandrade@uchospitals.edu, Front. Acta Neurochir (Wien) (2012) 154(8):1477–88. Good outcomes have been reported in studies focused on patients with gigantic dilations (83). Clin Neuropathol (2008) 27(1):37–52. doi:10.1191/1358863x02vm420ra, 56. Assuming a thickened, sigmoidal configuration, the dolichoectatic basilar becomes a space-occupying mass associated with recurrent ischemic strokes, multiple cranial palsies, or hydrocephalus. Smoker WR, Price MJ, Keyes WD, Corbett JJ, Gentry LR. Arch Neurol (2006) 63(2):234–41. When compared with patients without IADE, the same group of investigators found that patients with IADE and ischemic stroke have a higher prevalence of multilacunar state, severe leukoaraiosis, and enlarged perivascular spaces (20). Vertebrobasilar dolichoectasia refers to a markedly dilated and tortuous vertebrobasilar arterial system, occasionally presenting with thomboembolic episodes or symptoms related to local compressive effects, such as cranial nerve palsies. doi:10.3233/JAD-150759, 63. The etymology of the word dolichoectasia comes from the Greek dolikhós that means long, and ektasis that literally means distention of a tubular structure (22). Direct midbrain compression with obstructive hydrocephalus is a rare complication that mandates emergency ventricular decompression. As noticed, an objective definition of IADE has been limited due to the lack of established benchmarks. Table 1.
