Use of Shockwave intravascular lithotripsy for the treatment of symptomatic and severely calcified superior mesenteric artery stenosis.

Background: We present the use of intravascular lithotripsy as a treatment for highly calcified superior mesenteric artery stenosis.

Case Presentation: A 67-year-old diabetic man had chronic postprandial abdominal pain and weight loss. Computed tomography angiography revealed highly calcified stenosis of the superior mesenteric artery. Selective angiography confirmed severe stenosis. A Shockwave lithotripsy balloon catheter was successfully used via brachial access to modify calcified plaque and increase vascular lumen. After 12 months of follow-up the patient had gained weight and had no abdominal postprandial pain.

Conclusion: Intravascular lithotripsy could be considered a new treatment modality to modify calcified lesions in the visceral arteries. More controlled studies are needed to demonstrate the efficacy, safety and feasibility of this new technology.

Level Of Evidence: 4, Case Report.
