BACKGROUND AND PURPOSE Patients with hereditary hemorrhagic telangiectasia (HHT) are at risk for developing cerebral vascular malformations and pulmonary arteriovenous fistulae. We assessed the risk of neurological dysfunction from these malformations and fistulae. METHODS Three hundred twenty-one consecutive patients with HHT seen at a single institution over a 20-year period were studied. A...

Intravascular occlusion by various catheterization techniques was used to treat 27 cases of carotid-cavernous fistula, giant intracavernous aneurysm, and cerebral or dural arteriovenous malformation. Several case reports are presented. The detachable balloon technique proved valuable in the treatment of traumatic carotid-cavernous fistula and giant aneurysm. Calibrated-leak balloon catheterizat...

OBJECTIVE To review the experience with Onyx embolisation of cerebral arteriovenous malformation. DESIGN Prospective study. SETTING A regional neurosurgical centre in Hong Kong. PATIENTS Data of patients with cerebral arteriovenous malformation who underwent Onyx embolisation over a 14-month period were prospectively collected. RESULTS Eleven sessions of Onyx embolisation were performed...

PURPOSE To report the comprehensive superselective angiographic characteristics of aneurysms associated with cerebral arteriovenous malformations. METHOD One hundred consecutive patients referred for cerebral arteriovenous malformation embolization underwent preembolization superselective angiography. Superselective angiograms were obtained after microcatheterization of arteriovenous malforma...

Diffuse cerebral arteriovenous malformation (AVM) is a rare disorder of the brain and defined as diffuse infiltration of brain by complex vascular structures. It is usually associated with hereditary syndromes and presented with hemorrhage or seizure. We report a 20-year-old male patient who presented with drooping of the left eyelid. He had no skin lesion. The ophthalmological examination was ...

Arteriovenous malformations of the lung are rare pulmonary vascular disorders which can suddenly lead to life threatening complications. Haemothorax due to rupture of a pulmonary arteriovenous malformation (PAVM) is very rare. We report here a case of a 39 year-old lady who presented with an acute onset of shortness of breath due to right-sided massive haemothorax and was subsequently detected ...

PURPOSE Follow-up of vascular changes in a patient with congenital retinocephalofacial vascular malformation syndrome. METHODS MRI and cerebral angiography. RESULTS In a 36-year-old man, magnetic resonance imaging of the skull and cerebral angiography revealed left intracranial arteriovenous malformations. Follow-up observation of 27 years revealed no essential change of retinal and cerebra...

Intracranial arteriovenous malformation is rarely presented in newborns or infants. We describe an unusual case of congenital arteriovenous malformation of the brain with multiple sequestered grape-like venous sacs presented with congenital hydrocephalus. This 4-month-old girl born with a large head, presented with progressive hydrocephalus over a period of 4 months. The brain CT showed multilo...

Glioblastoma multiforme is the most common intracranial neoplasm of all primary central nervous system tumors. Glial tumors can present in different forms. Intracranial hemorrhage may occur in all central nervous system tumors to a varying degree and extent and may even be massive. A 58-year-old man presented with intraparenchymal hemorrhage manifesting as severe headache and vomiting. Cranial ...
