We report the use of IVL for lesion preparation prior to stentingin a patient with severely calcified superior mesenteric artery (SMA) stenosis.  \nCase presentation A 66-year-old man with type I adenocarcinoma of the esophagogastric junction (AEG Type I) and neoadjuvant FLOT chemotherapy was scheduled for Ivor Lewis esophagectomy. Preoperative CT angiography (CTA) revealed a high-grade ostial SMA stenosis due to extensive atherosclerotic calcification. To mitigate the risk of postoperative mesenteric hypoperfusion, percutaneous endovascular revascularization was performed. Following initial predilatation, IVL using a Shockwave 5.5 × 60 mm balloon catheter was employed for lesion preparation. Subsequently, an 8.0 × 24 mm balloon-expandable stent was successfully deployed with low-grade residual stenosis and no complications.  \nConclusion This case demonstrates that IVL represents a feasible and effective adjunct in the management of severely calcified visceral arterial lesions. It facilitates adequate lesion preparation and enables full stent expansion, even when the IVL balloon diameter is notably smaller than the stent diameter. This potentially represents a less traumatic approach to the vessel than alternative techniques. IVL may therefore be considered a therapeutic option in selected patients.  \nBackground  \nChronic mesenteric ischemia (CMI) commonly results from atherosclerotic narrowing of the mesenteric arteries and typically presents with postprandial pain and weight loss [1]. However, incidental SMA stenosis may also be detected during cancer staging or preoperative imaging. The SMA is the primary vessel supplying the small intestine. Its obstruction, especially in the context of limited collateral flow, can lead to clinically significant ischemia during physiologic stress, such as major abdominal surgery [2, 3].  \n*Correspondence:  \nRobert Terzis [robert.terzis@uk-koeln.de](robert.terzis@uk-koeln.de)  \n1 Institute for Diagnostic and Interventional Radiology, Faculty of Medicine and University Hospital Cologne, University of Cologne, Kerpener Straße 62, Cologne 50937, Germany  \nEndovascular treatment options include percutaneous transluminal angioplasty (PTA) with stent placement [4]. However, dense calcification poses technical challengesand increases the risk of perforation, suboptimal expansion, recoil, or dissection [4]. Intravascular lithotripsy (IVL) has recently emerged as an innovative approach that facilitates calcium modification using sonic pressure waves to fracture intimal and medial calcifications, thus enhancing vessel compliance prior to stenting [5, 6].  \nCase presentation  \nA 66-year-old male patient was diagnosed with adenocarcinoma of the esophagogastric junction type I (AEG Type I), with tumor extension from 40 to 44 cm from the alveolar ridge.
