[Antegrade puncture of the superficial femoral artery: a pilot project].

Antegrade puncture of the femoral artery is often the first step in angioplasty or thrombolysis of the lower limb. Because of presumed complications, mostly from anecdotal literature, the common femoral artery is the preferred site of entry. From there, selective catheterization of the superficial femoral artery can be performed. This two-step procedure is sometimes long and difficult for both the patient and the radiologist. To improve the ease and the rapidity of this procedure, the author performed direct antegrade puncture of the superficial femoral artery during 25 consecutive antegrade approaches. The only local complication was hematoma, which developed in two patients but disappeared spontaneously. Aggravating factors were the size of the catheters used and fibrinolytic therapy in one of the affected patients. The results of this pilot study suggest strongly that direct antegrade puncture of the superficial femoral artery is safer than might be expected from the literature, which deals primarily with retrograde puncture. This approach must now be systematically compared with the "classic" common femoral artery approach.
