Endovascular revascularization of heavily calcified occlusion in superior mesenteric artery using Transcollateral approach.

ABSTRACT:

Background

Mesenteric ischaemia is often a manifestation of severe vascular disease involving the superior mesenteric artery (SMA). Endovascular revascularization is challenging in a chronic total occlusion (CTO) of SMA.

Case presentation

A-73-year-old male patient was referred to our hospital because of a 2-year history of post prandial abdominal angina. Computed tomography (CT) images revealed a heavily calcified CTO in the ostium of SMA and three-dimensional CT (3D-CT) detected pancreaticoduodenal arcade with filling from the celiac artery. Then, endovascular procedure was attempted; however, angiography did not show the collateral route suitable for transcollateral approach. As demonstrated on the CT, we were successful in passing a guidewire through the SMA-CTO via the
