Pretreatment imaging of peripheral vascular malformations
Peripheral vascular malformations (VMs) are complex and diverse vascular lesions which require individualized pretreatment planning. Pretreatment imaging using various modalities, especially magnetic resonance imaging and time-resolved magnetic resonance angiography, is a valuable tool for classifying peripheral VMs to allow proper diagnosis, demonstrate complete extent, identify the nidus, and...
متن کامل[Percutaneous treatment of peripheral vascular malformations].
OBJECTIVE Vascular malformations are uncommon pathologic entities in which surgery is usually not possible or is inefficient. Our experience with the percutaneous treatment of peripheral vascular malformations, by means of transarterial embolization or direct puncture is here reported. MATERIAL AND METHODS During the 1993-1997 period a total of 35 patient, 20 females (57%) and 15 males (43%) ...
متن کاملMR imaging of cerebral vascular malformations.
Fifteen vascular malformations, including six supratentorial arteriovenous malformations (AVMs), three venous malformations, and six brainstem vascular malformations, were examined on 0.5 T magnetic resonance (MR) and GE 9800 and 8800 computed tomographic (CT) scanners. All the malformations were shown by MR, and the arterial and venous drainage of AVMs was precisely delineated. Hematoma was al...
متن کاملMR Imaging of Angiographically Occult Vascular Malformations
Eleven patients with 15 angiographically occult arteriovenous malformations were studied by magnetic resonance (MR) imaging and computed tomography (CT). Five patients had biopsy proof; six were clinically diagnosed from the long-term clinical follow-up (more than 3 years) and imaging features. Of the 15 lesions, 11 were recognized by both CT and MR. Each method was falsely negative for two les...
متن کاملModern Developments in Peripheral Vascular Surgery
One of the most important advances in arterial surgery has been the advent of direct operations upon arteries including the use of various forms of grafting, and these have partly displaced operations on the sympathetic nervous system. The largest field for this work is the ever increasing problem of atherosclerosis but no less important, though less common, is the place of direct surgery in pa...
