Spontaneous retrograde dissection of the right common iliac artery: a case report

Spontaneous retrograde dissection of the right common iliac artery incidentally imaged by intra-arterial digital subtraction angiography (IADSA) and confirmed by contrast infusion computed tomography (CT) is reported. This is the first case report of this extremely rare condition, but histologic verification could not be obtained. The usefulness of IADSA in mapping during catheterization complicated by marked resistance is underscored.
