A new percutaneous technique for occluding arterial flow to massive congenital A-V malformations to prevent major hemmorrhage during resection

In this experience, life-threatening hemorrhage and operative excision of large cranial congenital A-V malformations were managed in two young patients. The major feeding arteries were selectively occluded, shrinking the masses dramatically and greatly facilitating resection which could then be followed by immediate skin grafting. This technique employs standard technology for arteriography and catheterization and should have widespread usefulness in children for control of large Congenital AV Malformations and other vascular masses, including malignant tumors.
