Stent Placement for Spontaneous Isolated Superior Mesenteric Artery Dissection via Radial Approach with Intravascular Ultrasound Assistance

Spontaneous isolated superior mesenteric artery (SMA) dissection was a sporadically reported vascular event, but an increasing number of case reports have been published in recent years. The optimal therapy opinions are widely divided. Despite there still being no consensus on the best treatment, an increasing number of patients in recent years have been reported to be treated successfully by non-surgical rather than surgical approaches. Here, we present a 47-year-old man with SMA dissection, who received percutaneous stent placement. According to our experience, successful stent placement would be achieved more easily by radial approach and intravascular ultrasound (IVUS) assistance.
