Abstract

Objective: We aimed to investigate the efficacy of the insertion-support guiding catheter (ISGC) for approaching target lesions during endovascular therapy in patients with severe atherosclerotic or tortuous arteries.

Case presentations: The ISGC is an 8 Fr, JB2 shape, stiff-type, short guiding catheter. We used ISGC for 52 patients between April 2007 and March 2018, microcatheters or therapeutic devices were delivered to target lesions via ISGC in 46 (88.4%) of the 52 patients, and none of them developed associated complications. Herein, we present three representative cases.

Conclusions: An ISGC is useful for vascular intervention in patients with atherosclerotic or tortuous arteries.
