title: Graft patency evaluation with DSA after reconstructive venous surgery.
abstract: Evaluation of graft patency following reconstructive venous surgery may be difficult, especially in patients in whom a distal arteriovenous fistula has been constructed. We describe a method of visualizing these venous bypass grafts using digital subtraction angiography that is easy and provides satisfactory results.
