ObjectiveTo compare the short-term and medium-term result of stent implantation with pharmaceutical thrombolysis in patients with acute superior mesenteric artery occlusion.MethodsFrom January, 2004 to December, 2008, thirty-five patients diagnosed acute superior mesenteric ischemia, 12 patients treated with stent implantation (interventional therapy group) and 23 patients with pharmaceutical thrombolysis (thrombolytic therapy group). Interventional therapy group treated with balloon dilatation and stent implantation assisted with anticoagulation, antiplatelet and vascular dilation agents. Thrombolytic therapy group used urokinase combined with anticoagulation, antiplatelet and vascular dilation agents. All patients had taken clopidogrel and aspirin orally after discharged and followed up. The clinical effects of both groups were evaluated separately and the Fisher exact test was used to analysis the significant differences.ResultsIn the 23 cases of thrombolytic therapy group, 7 cases was effective, 16 cases was ineffective (7 cases aggravated or died, 9 cases turn to surgical operation). In the 12 cases of interventional therapy group, 10 cases treated with stent implantation (1 case died of acute cardiac infarction 3 days after interventional operation), 2 cases failed in recanalizing. All patients were followed up after discharged (range 1 - 48 months, mean 15 ± 12 months), 1 case in thrombolytic therapy group was stable, 6 cases died of the recurrence of acute superior mesenteric artery occlusion; 7 cases in interventional therapy group was stable, 1 case died of acute cardiac infarction 20 months after interventional operation (intestinal ischemia not appeared), 1 case had intestinal ischemia reoccurred and recovered by superior mesenteric artery thrombolysis.ConclusionsIn the treatment of acute superior mesenteric ischemia, stent implantation was obviously superior to pharmaceutical thrombolysis in improving intestinal ischemia and survival, therefore it could provided a reliable choice for the patients who had not appeared intestinal necrosis.
