β¦ Synopsis
Twenty-one intracranial arteriovenous malformations (17 pial, 3 dural, 1 mixed) have been studied by digital intravenous subtraction angiography (DIVA). A comparison with conventional arteriography has been performed. In this series DIVA was 100% diagnostic for AVM. However DIVA missed some small arterial pedicles (1 lenticulostriate, 1 thalamoperforating, 1 anterior choroidal artery and 2 pharyngeal arteries). Sectorial analysis of AVM needs selective arteriography. DIVA is a good method for screening and follow-up of intracranial AVM, but selective arteriography is often still necessary to complete the pre-operative evaluation.

Surgical excision is the only treatment method that immediately prevents increased morbidity or mortality as a result of hemorrhage from arteriovenous malformations (AVMs). For those lesions located deep within the cerebral hemispheres or near eloquent areas, conventional surgical resection may be a
Arteriovenous malformation (AVM) is usually congenital, but an acquired type is also known, of which most are due to a previous injury. We report six patients with acquired digital AVM, all having a small patch of AVM localized to the tip of one finger, and therefore quite different from ordinary AV
