From: Cephalic arch stenosis: an analysis of outcome by type of first intervention
A A CAS in the medial segment (domain C) [i.e., confluence with the subclavian vein] was described on a diagnostic fistulogram, despite the suboptimal view (dotted lines). B The patient underwent expedited SG insertion, but the operator erroneously stented the tortuous lateral aspect of the CA (braces). C The cephalic conduit was found to be occluded from the level of the shoulder after 4 weeks from SG insertion (black arrows)
