• Progressive Dementia

  Although the number of patients is small, the risk for progressive dementia in this group is higher than in patients with other dural AVMs. [neupsykey.com]

• Continuous Murmur

  A continuous murmur at the base of the skull can be heard in 80% of the newborns due to the AV fistula. It can also be detected on in utero Ultrasonography in the third trimester of pregnancy [3]. [medcraveonline.com]

• Left Ventricular Dysfunction

  Theoretically, when left ventricular dysfunction owing to chronic volume overload occurs, digoxin should be beneficial. Dobutamine and dopamine may be used in severe situations to improve cardiac output. [radiologykey.com]

• Loss of Initiative

  Six had a large degree of vascular steal demonstrated by cerebral angiography and all had significant parenchymal loss on initial CT. [ncbi.nlm.nih.gov]

• Headache

  The child developed normally over the next six years, but then a sudden headache occurred, followed quickly by coma. CT revealed an intraventricular hemorrhage from the malformation and evidence of hydrocephalus. [nejm.org]

  Other features may include increased head circumference resulting from hydrocephalus, unusually prominent veins on the face and scalp, developmental delay, persistent headache, and other neurological findings. [1] [2] [3] Vein of Galen aneurysm is often [rarediseases.info.nih.gov]

  The initial symptom typically falls into one of four categories: intracranial hemorrhage, seizure, headache and focal neurologic problems. Children are more likely to present with hemorrhage than adults. [childrenshospital.vanderbilt.org]

  Sometimes they can cause seizures or headaches. AVMs are rare. The cause is not known, but they seem to develop during pregnancy or soon after birth. Doctors use imaging tests to detect them. Medicines can help with the symptoms from AVMs. [icdlist.com]

  These patients usually present with headache and seizures. A small number of patients may also present with developmental delay, focal neurological deficits, proptosis (bulging eyes) and epistaxis (bleeding nose). [neurosurgery.ufl.edu]

• Recurrent Headache

  Case 2 An 8-year-old boy presented with 7 months history of recurrent headaches that were worse in the morning and associated with blurring of vision. The headaches were preceded by a 1-week history of irrational speech and behavior. [wajradiology.org]

• White Matter Lesions

  MR imaging ( Fig. 12 ) may show focal white matter lesions or diffuse destruction of the brain (the melting brain), which is generally associated with severe cardiac insufficiency. [radiologykey.com]

• Visceromegaly

  On physical examination, he presented in an adequate nutritional status; head circumference was normal, without visceromegalies or evidence of cardiac failure, but with an irregular breathing pattern. [austinpublishinggroup.com]

Surgery is not indicated as a treatment for VGAM, except in very rare cases. Patients undergoing VGAM treatment should have regular programmed clinical and morphological examinations. [orpha.net]

Endovascular treatments involve delivering drugs, balloons, or coils to the site of the malformation through blood vessels via catheters. These treatments work by limiting blood flow through the vein. [en.wikipedia.org]

Figure 4 summarizes this treatment algorithm. Figure 4 Treatment algorithm Cardiology assessment of cardiac function and superior vena cava flow should proceed right away. [surgicalneurologyint.com]

If the treatment goal cannot be achieved in one session, the patient will undergo a second session of treatment another day. [neupsykey.com]

Three of the seven children with mural lesions died shortly after treatment; the other four achieved normal or near-normal development after treatment. [ajnr.org]

Prognosis The neurological prognosis for VGAM with early treatment is excellent; however, the prognosis is poorer for patients with severe neonatal malformations. The documents contained in this web site are presented for information purposes only. [orpha.net]

Treatment and prognosis Prior to endovascular intervention, the prognosis was dismal, with 100% mortality without treatment and 90% mortality following surgical attempts 5. [radiopaedia.org]

The prognosis of the disease has been notably dark, with death rates reaching 100% in the past. [nature.com]

Endovascular embolization indeed greatly improved the prognosis of patients. [ncbi.nlm.nih.gov]

Clinical and laboratory findings are described in the case of a patient with a vein of Galen aneurysm who presented with recurrent aseptic meningitis for which no etiology could be identified. [ncbi.nlm.nih.gov]

The etiology of this outflow obstruction is unknown but may be related to underdevelopment of the jugular bulb, abnormal skull base maturation, and high-flow angiopathy of the venous system causing kinking or thrombosis at the tentorial or dural edge [clinicalgate.com]

(Etiology) The exact cause of Vein of Galen Malformation is not known. It is believed that genetic changes in the developing fetus in the first trimester can lead to this abnormality. [dovemed.com]

CONCLUSION: Our data demonstrate that most treated children survive and undergo normal neurological development; an understanding of the clinical, anatomical, and pathophysiological features of VGAM has, therefore, reversed the former poor prognosis. [ncbi.nlm.nih.gov]

The varied clinical presentations and their distinctive and complex angioarchitecture make it important for the caring physician to understand their embryological and pathophysiological aspects. [scienceopen.com]

In a child who has not presented with cardiac failure, the aim of endovascular therapy is to prevent consequences of chronic cerebral venous hypertension and to promote normal cerebral development. Please contact our office for more information. [neurosurgery.ufl.edu]

The high pressure in the veins can prevent the infant’s brain from draining adequately. This can lead to widespread brain injury and sometimes causes severe loss of tissue in the brain. [childrenshospital.org]
