title: Shepherd's hook technique for superselective catheterization of hepatic arteries.
abstract: From October 2013 to March 2014, the shepherd's hook technique was attempted in 21 patients for superselective catheterization of the hepatic artery. The technique was successful in 18 of 21 patients (86%).The indications for using the shepherd's hook technique were acute angulation < 60 degrees (n = 14), a small feeder artery from a large hepatic artery at a right angle (n = 6), or obtuse angulation from the complex parent artery (n = 1). The shepherd's hook technique is a useful tool in superselective catheterization of hepatic arteries with complex geometry.
