Superselective embolization of visceral arterial branches has become integral in the management of acute lower gastrointestinal (GI) hemorrhage. The present study aimed to evaluate the success of superselective embolization as a primary therapeutic modality in the control of lower GI hemorrhage and to identify factors associated with rebleeding and surgical intervention after the procedure.

We performed a retrospective review of all cases of superselective embolization for acute lower GI bleeding during a 7‐year period (December 2000–October 2007) in a single 1,300‐bed hospital in Singapore.

Various clinical and hematologic factors were analyzed against rebleeding and surgical intervention after the procedure.

A total of 265 patients underwent …
