[Placing two parallel catheters by Seldinger's approach through the femoral artery for CT angiography and CT during arterioportography: evaluation of efficacy and safety].

The purpose of this study was to evaluate the efficacy and safety of placing two parallel catheters by Seldinger's approach through the femoral artery for CT angiography (CTA) and CT during arterioportography (CTAP). We performed an analysis of 30 patients. Two introducers were successfully placed in all cases. Only one minor complication was observed, a localized inguinal hematoma. The CTA/CTAP procedures were successful in all patients except six who had anatomical variations of the hepatic arterial supply. Our methods proved to be useful and safe for patients with standard hepatic arterial supply.
