The “Little AVM”: A New Entity in High-flow versus Low-flow Vascular Malformations

BACKGROUND Arteriovenous malformations (AVMs) are high-flow lesions with abnormal connections between arteries and veins without an intervening capillary bed. Infrequently, the radiographic diagnosis of a vascular lesion will not support the clinical diagnosis of an AVM. These "discrepant" lesions are not adequately captured within the current classification system and represent a treatment dil...

Sirolimus: A Rapid Treatment for Coagulopathy Because of Vascular Malformations

The use of foam sclerotherapy to treat low-flow vascular malformations of the head and neck

Liquid sclerotherapy, laser and surgery have been used in the treatment of head and neck vascular anomalies with variable success for many years. A multidisciplinary team consisting of plastic surgery, maxillofacial surgery and interventional radiology currently treats such lesions by converting liquid sclerosant into foam. Foam sclerotherapy is currently used successfully to treat varicosities...

Slow-flow vascular malformations of the pons: capillary telangiectasias?

PURPOSE To report clinical and MR features that suggest telangiectatic vascular malformations of the pons: METHODS The MR scans and clinical data of 12 patients demonstrating an enhancing pontine lesion with minimal or no signal abnormality on T2-weighted images were reviewed. None of the patients underwent angiography or biopsy. Follow-up scans, available for all patients between 3 weeks and...

Embolization of high-flow craniofacial vascular malformations with onyx.

BACKGROUND AND PURPOSE Various techniques and materials have been used for the endovascular treatment of craniofacial high-flow arteriovenous vascular malformations, because their rarity precludes standardization of their treatment. The aim of this retrospective review is to assess Onyx as the primary embolic agent in the treatment of these vascular malformations. MATERIALS AND METHODS Six pa...
