UNLABELLED: Article presents a rare case of posttraumatic pseudoaneurysm and A-V fistula between deep femoral artery and vein in 16 year old patient with stab wound in middle third of the lateral side of left femoral region. There were no signs of arterial injury on initial angiogram. During the observation we noticed subcutaneous bruise on the posterior side of the femoral region, and strong systolic murmur by ordinary auscultation over the involved region as a significant sign of the A-V fistula. At day 3, CT angiogram and Doppler analysis showed 4 cm sized false aneurysm combined with A-V fistula between distal portion of the deep femoral artery and vein. We made ipsilateral transfemoral catheterization and coiling of the feeding arterial branch with good immediate result, but at next Doppler checking, appearance of the same picture was disappointing. After we recognized retrograde filling through distal collateral artery, technically unsuitable for endovascular procedure, conventional surgery with posterolateral approach was indicated. An excision of the pseudoaneurysm, and ligation of the A-V fistula was done with good postoperative result. CONCLUSION: Obliterative endovascular procedure is a method of choice, but sometimes can not guarantee satisfactory result. In those cases conventional surgery is recommended.
