Percutaneous recanalization and stent placement in chronic proximal superior mesenteric artery occlusion
1Department of Radiology, University Hospitals, Herestraat 49, B-3000 Leuven, Belgium.
Insights
Chronic superior mesenteric artery (SMA) occlusion, causing intestinal ischemia, was successfully treated. Local catheter-directed thrombolytic therapy, angioplasty, and stenting resolved the blockage, relieving symptoms.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Gastroenterology
Background:
- Atherosclerotic stenosis in visceral arteries, particularly the superior mesenteric artery (SMA), can lead to severe intestinal ischemia.
- Chronic proximal SMA occlusion presents a significant risk of bowel infarction and mortality.
- Surgical intervention for SMA occlusion can be complex and carry substantial risks.
Abstract:
Atherosclerotic stenosis involving the proximal portion of at least two visceral arteries usually causes symptoms of intestinal ischemia and can lead to massive bowel infarction and death. This report describes a case of chronic proximal occlusion of the superior mesenteric artery (SMA) in a 51-year-old man, successfully treated by local catheter-directed thrombolytic therapy, followed by balloon dilatation and stent placement of the residual atherosclerotic stenosis. At 3 months follow-up, the patient was free of symptoms. This case shows that local thrombolytic therapy, percutaneous transluminal angioplasty and stent placement can be useful in the treatment of chronic atherosclerotic occlusion of the proximal SMA.
