What are the symptoms of vertebrobasilar Dolichoectasia?
The mass effect of VBD can compress the nearby brainstem and cranial nerves, leading to symptoms such as weakness, dizziness, choking on water, cranial nerve damage, neurogenic hypertension, or pseudo space-occupying lesions within cranial fossa [4, 6, 29-31].
Is a fusiform aneurysm serious?
Rupture of fusiform aneurysms, especially those located in the posterior circulation, is often lethal, despite aggressive treatment.
What is Dolichoectasia of the left vertebral artery?
Abstract. Dolichoectasia of vertebrobasilar artery is a condition in which the vertebral/basilar artery is elongated, distended and tortuous. It is usually asymptomatic. It may present with compressive or ischemic symptoms. Hydrocephalus as a complication of vertebrobasilar dolichoectasia is rare.
What causes Dolichoectasia?
Dolichoectasia is associated with hypertension, older age, and male sex; it is also reportedly associated with heritable connective tissue disorders such as Marfan syndrome and Ehlers–Danlos syndrome (2).
How do you fix vertebrobasilar insufficiency?
Treatment for vertebrobasilar insufficiency
- Medication and lifestyle changes. Patients who have vertebrobasilar insufficiency, a history of stroke, or TIA (“mini-stroke”) should quit smoking immediately, attempt to lower cholesterol levels through diet, and exercise regularly.
- Open surgical repair.
- Endovascular repair.
What is Ectatic vertebral artery?
Vertebral artery ectasia refers to an abnormal dilatation of the vertebral artery. It is also known as a dolichoarterial loop (of Danziger).
How do you fix a fusiform aneurysm?
All fusiform aneurysms have been historically treated with different open surgical treatment modalities, including Hunterian ligation, trapping, surgical bypass, and clip reconstruction techniques. However, endovascular therapy has emerged as the primary treatment modality for PCFAs over the past decade.
What is the most common location for fusiform aneurysm?
The most frequent site of fusiform aneurysm was a middle cerebral artery.
What is in the circle of Willis?
Overview. The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
How common is a dolichoectasia?
Introduction. Vertebrobasilar dolichoectasia (VBD) is a vascular anomaly characterized by marked ectasia, elongation, and tortuosity of the vertebrobasilar arteries, with a reported prevalence of 0.05–18%.
What do we know about Fusiform dolichoectatic vertebrobasilar aneurysms?
OBJECTIVE Fusiform dolichoectatic vertebrobasilar aneurysms are rare, challenging lesions. The natural history of these lesions and medium- and long-term patient outcomes are poorly understood.
What is a dolichoectatic aneurysm?
Fusiform and dolichoectatic aneurysms occur in any of the intracranial arteries, but particularly in the vertebrobasilar and internal carotid arteries. They present in a wide variety of ways, ranging from hemorrhage to cranial nerve or brain parenchymal compression to embolic stroke.
What is dolichoectasia?
Background: Dolichoectasia is a rare disorder of the cerebral vasculature consisting of vascular elongation, widening, and tortuosity, usually involving the vertebral and basilar arteries. Its neurological symptoms and signs are highly variable. Case Description:
What are the symptoms of a fusiform aneurysm?
Presentation and course Fusiform or dolichoectatic aneurysms may present with headache or other symptoms related to compression of adjacent brain structures, with infarction or transient ischemic attacks, or with rupture and hemorrhage. Often, however, they are discovered incidentally.
