Acute mesenteric ischemia (AMI) represents a severe complication of chronic mesenteric ischemia (CMI) which is a disorder caused by severe stenosis or occlusion of mesenteric arterial supply. If untreated, patients could face mesenteric infarction and death.
A 41-year-old female smoker and drug abuser, previously treated with angioplasty and stenting of the superior mesenteric artery (SMA) for CMI four years before, was admitted to our institution suffering from acute abdominal pain due to complete occlusion of the stent. After a few hours of thrombolytic therapy, she experienced sudden worsening of clinical conditions, including AMI, due to complete rethrombosis of the SMA. Thereafter, she underwent urgent thrombectomy and a subsequent retrograde 6 mm prosthetic aorto-mesenteric bypass graft. The patient reported complete relief of symptoms afterwards. A CT scan at 1-month follow-up showed primary patency of the bypass in the absence of clinical recurrence.
In cases of CMI, treatment options include surgical, endovascular or hybrid approaches. Endovascular therapy, based on percutaneous angioplasty with or without stenting, seems to be effective, although it can have worse midterm and long-term results.
In patients already treated with an endovascular revascularization of the SMA or celiac trunk (CT), open surgical repair through a single retrograde aorto-mesenteric prosthetic bypass in cases of acute mesenteric ischemia, seems to offer a valid and safe approach in order to prevent bowel infarction.

急性肠系膜缺血(AMI)是慢性肠系膜缺血(CMI)的严重并发症,由肠系膜动脉供应严重狭窄或闭塞引起。如果不治疗,患者可能会面临肠系膜梗死和死亡。
一位 41 岁的女性吸烟者和药物滥用者,四年前因 CMI 接受了经皮腔内血管成形术和支架置入术治疗肠系膜上动脉(SMA),因支架完全闭塞而出现急性腹痛,被收入我院。溶栓治疗数小时后,她突然出现 AMI 等临床状况恶化,由于 SMA 完全再血栓形成。随后,她接受了紧急血栓切除术和随后的逆行 6 毫米人工主动脉-肠系膜旁路移植术。此后,患者报告症状完全缓解。1 个月后的 CT 扫描显示旁路的原发性通畅,无临床复发。
在 CMI 病例中,治疗选择包括手术、血管内或杂交方法。血管内治疗基于经皮血管成形术伴或不伴支架置入术,似乎是有效的,尽管它可能有更差的中期和长期结果。
对于已经接受 SMA 或腹腔干(CT)血管内再血管化治疗的患者,在急性肠系膜缺血时通过单一逆行主动脉-肠系膜人工旁路进行开放手术修复,似乎是一种有效且安全的方法,可预防肠梗死。
