An additional three cases involved use of the HSS for superior mesenteric artery cannulation in patients with mesenteric ischaemia. The device was also used once in each of the following cases: contralateral common iliac cannulation, cannulation of contralateral internal iliac artery for coil embolisation, and access of a contralateral iliac branched device.
