This retrospective study evaluates our experience with clinically diagnosed nonocclusive mesenteric ischemia after cardiopulmonary bypass. Twenty-three of 3,600 consecutive patients suffered from splanchnic malperfusion. Symptoms developed between day 2 and 6 postoperatively in 18 of 23 patients. ⋯ Patients with angiographically proven nonocclusive mesenteric ischemia were treated with intra-arterial bolus injection and subsequent intra-arterial infusion of tolazoline combined with heparin sodium. The overall mortality rate was 30% (7 of 23). Infusion therapy with tolazoline and heparin seems to be a successful treatment modality for clinically diagnosed mesenteric ischemia.
