Abstract: A vascular graft (30) comprises a proximal inlet section (31), a first distal section (32) and a second distal section (33). The first distal section (32) and the second distal section (33) are attached to the proximal inlet section (31) at a Y-shaped bifurcation region. In use the proximal inlet section (31) is attached to a first part (34) of a host artery in an end-to-side anastomosis. A second part (35) of the host artery is cut to form a first section (36) of the host artery on a first side of the cut and a second section (37) of the host artery on a second side of the cut. The first distal section (32) is attached to the first section (36) in an end-to-end anastomosis, and the second distal section (33) is attached to the second section (37) in an end-to-end anastomosis.
