Use of Multimodal Interventional Radiology with an Intracerebral Artery Stent Retriever for Acute Superior Mesenteric Artery Thrombosis: A Case Report.

Acute superior mesenteric artery thrombosis is usually fatal; however, early intravascular treatment using a mechanical thrombectomy device can be an effective intervention. A 70-year-old man with atrial fibrillation presented with sudden abdominal pain; superior mesenteric artery thrombosis was confirmed using contrast-enhanced computed tomography. Thrombolysis, mechanical fragmentation, aspiration, and thrombectomy were successfully performed using the Trevo® XP ProVue stent retriever via a brachial approach, and intestinal necrosis was avoided. Thus, intravascular treatment of superior mesenteric artery thrombosis can be performed using a relatively low-profile catheter and a brachial artery approach, allowing the implementation of a multimodal interventional radiological approach tailored for individual cases.
