Vascular Anomalies (Part II): Interventional Therapy of Peripheral Vascular Malformations

[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%) ...

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...

Sirolimus: A Rapid Treatment for Coagulopathy Because of Vascular Malformations

Classification, diagnosis, and interventional radiologic management of vascular malformations.

Vascular anomalies are comprised of either hemangiomas or vascular malformations.Low-flow vascular malformations can be divided into capillary, venous, and lymphatic types and are usually present at birth, undergo pari passu growth, and produce symptoms related to mass effect or stasis. High-flow malformations are comprised pre-dominantly of arteriovenous malformations that follow a more aggres...

[Vascular malformations (II). Diagnosis, pathology and treatment].

Diagnosis of vascular malformations is essentially clinical, based on the evolution and morphology of lesions. A biopsy is rarely needed to evaluate the nature of the vessels. Imaging examinations are necessary to assess the extension of malformations as well as the osteomuscular and visceral compromise. New techniques such as 3D angio-CT scan and angio-MRI improve the diagnosis of some vascula...
