Percutaneous retrograde revascularization of chronic occlusions of the superior mesenteric artery via collaterals of the celiac artery

Abstract

Purpose: To evaluate the technical success of percutaneous retrograde revascularization of the superior mesenteric artery (SMA) via the celiac artery (CA) in patients with chronic mesenteric ischemia (CMI). Methods: We performed a retrospective review of three patients with chronic total occlusions (CTOs) of the origin of SMA which were recanalized retrograde via collaterals of the CA after frustrating attempt of antegrade revascularization from the abdominal aorta in our institute between May 2019 and June 2020. Results: All technical procedures of retrograde revascularization of CTOs of SMA via collaterals of the CA were successful. The clinical outcome resulted in a sustained resolution of abdominal pain in all cases. Conclusion: Retrograde recanalization of SMA via collaterals from the CA seems to be a successful endovascular option for patients with CMI and a chronically occluded superior mesenteric artery when antegrade recanalization fails as far as it can be concluded from the small number of presented cases.
