Occlusion of the abdominal aorta and iliac arteries can occur from thrombosis superim-posed on arteriosclerosis obliterans, from thrombosis resulting from unsuccessful surgery on those vessels, or from embolism arising from intracardiac or other sources proximal to the area occluded. Restoration of continuity of the obstructed vessel by thrombendarterectomy * or by resection and graft † has been reported. The latter method has been the method of choice in our clinic.
There are certain patients, however, who are poor surgical risks or who present unfavorable local conditions for reconstruction of the vessels themselves, in whom a direct attack on the aorta or common iliac may seem inadvisable and a simpler, or bypass, procedure preferable. The use of the splenic artery as the vessel of origin for the bypass has been suggested by Glenn,8 in a patient with low thoracic aortic coarctation, and by Freeman and Leeds,9 in two patients with
