Advanced Percutaneous Endovascular Techniques for the Treatment of Acute Bowel Ischemia-Retrograde Endovascular Recanalization and Lithotripsy-Assisted Angioplasty: Case Report.

Acute bowel ischemia that develops secondarily to thrombotic occlusion of the superior mesenteric artery is a life-threatening abdominal emergency. Although an open surgical repair is still the main treatment modality for this pathology, percutaneous endovascular revascularization is currently recognized as an alternative therapeutic option. However, in some patients, endovascular repair of the occluded superior mesenteric artery is technically very challenging. We provide technical details of percutaneous endovascular revascularization of the superior mesenteric artery in a patient presenting with highly calcified plaques extending to the aortic wall, with an associated risk of the aortic wall rupturing after standard balloon angioplasty. The patient was managed using the lithotripsy-assisted angioplasty, in order to minimize the risk of aortic injury. During endovascular reconstruction of the superior mesenteric artery for acute bowel ischemia, on the one hand, a full revascularization of the ischemic bowel should be achieved. On the other hand, the procedure should not be too aggressive. In this technical note, we demonstrated that even very difficult cases can be successfully managed endovascularly, if a tailored approach is used and proper endovascular devices are applied.
