置管溶栓治疗急性肠系膜上动脉血栓栓塞

目的探讨肠系膜上动脉(SMA)造影和血栓内置管溶栓治疗急性SMA血栓栓塞的应用价值。方法经股动脉穿刺置管造影明确诊断SMA血栓栓塞患者8例,取栓并将导管头端埋入血栓内溶栓,术后保留导管接微量泵继续缓慢溶栓。结果4例溶栓治疗成功;3例小肠坏死行部分小肠切除加端端吻合术,3例中2例痊愈,1例术后并发心力衰竭而死亡;1例消化道大出血死亡。结论血管造影可明确诊断SMA栓塞的位置和肠管缺血范围,早期血栓内置管取栓加溶栓可取得满意疗效。

Treatment of superior mesentery arterial embolism with transcatheterizing thrombolysis

Objective To discuss the treatment of superior mesenteric arterial thrombo-embolism through superior mesenteric arterial angiography and transcatheterizing thrombolysis. Methods After diagnosis of superior mesenteric arterial thrombo-embolism through percutaneous transluminal angiography, the embolism was cleared out and then the inner tip of catheter was implanted within embolus for slow continuously thrombolysis with the outer tip of catheter connected to the infusion pump. Result Four cases succeeded with thrombolysis; 3 cases were performed with partial small intestinal excision with necrosis. Two cases healed. One case died of heart failure postoperatively and another case died of massive digestive tract hemorrhage. Conclusions Angiography can help to confirm the position of superior mesentery arterial thrombosis and the extent of intestinal ischemia. Early intrathrombus catheterization for clear out and thrombolysis can obtain satifactory prognosis.
