Patch graft angioplasty is a useful technical alternative for arteriotomy closure. In our experience, patch graft angioplasty has been reserved for patients with recurrent stenosis, those with smaller than normal arteries, and those who have radiation arteriopathy after previous treatment for a malignancy. Patch graft angioplasty is also useful for the repair of smaller caliber vessels such as the vertebral artery. Any closure that decreases the arterial circumference represents an indication for patch graft angioplasty. Various materials, such as autogenous vein or artery and synthetic materials, have been used. This article reviews the advantages and technical aspects of patch angioplasty.
