BACKGROUND Hemangioma is the most common tumor of neonatal period and it is almost always appeared by the end of the first week of life and can be found mostly in head and neck area. This study evaluated the synergistic effect of bleomycin, triamcinolone and epinephrine in treatment of hemangioma and arteriovenous malformations. METHODS In this multicenter study, a combination of bleomycin, t...

PURPOSE To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations. METHODS Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography. RESULTS Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. ...

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...

The literature on spinal vascular malformations contains a great deal of confusing terminology. Some of the nomenclature is inconsistent with the lesions described. Based on the experience of the senior author (R.F.S.) in the treatment of more than 130 spinal cord vascular lesions and based on a thorough review of the relevant literature, the authors propose a modified classification system for...

Riley-Smith syndrome Macrocephaly, pseudopapilloedema, lymphaticovenous malformation Introduction An arteriovenous malformation (AVM) is defined as an abnormal communication between an artery and vein that bypasses a capillary bed. These lesions may present as isolated, innocuous cutaneous naevi, or they rarely may take the form of life-threatening systemic shunts involving large portions of th...

Cerebral arteriovenous malformations infrequently complicate pregnancy. We sought to determine the neurologic, obstetric, and ethical significance of such malformations. We present the clinical course of 2 pregnant women with arteriovenous malformations who experienced cerebral hemorrhage and a loss of capacity for decision making. We also review the neurologic and obstetric significance of art...
