[Reconstructive procedures in chronic occlusive processes of the intestinal arteries].

Three approaches are considered: the left thoracoabdominal approach, the right-sided retro- or supracolic route and the transabdominal access. Aorto-common hepatic venous bypass grafting is the preferred procedure in singular occlusions of the celiac axis. Reimplantation and aorto-mesenteric venous bypass are the treatments of choice in singular occlusions of the mesenteric artery. Occlusions of both upper intestinal arteries can be treated with a venous bridge bypass graft or by transaortic end-arterectomy. Operative mortality is low (0.9%). Remaining occlusion and recurrent symptoms occurred in 12 of 92 patients.
