[Experience with transvenous xeroarteriography in vascular surgery (author's transl)].
The edge contrast pattern in Xeroradiography allows blood vessels to be delineated with highly reduced concentration of radiopaque fluid. The contrast material is injected rapidly into a cubital vein. The brachial arteries are opacified 3--8 sec. and the femoral arteries about 7--15 sec. after the injection is finished. The arteriograms are of good quality which equals direct conventional angiography, if the vessels are not overlayed by bone structures. Thus the popliteal artery can be judged best in lateral view. The indications for transvenous Xeroarteriography are preoperative diagnosis especially in high risk patients, angiographic diagnosis of soft tissue tumors and postoperative control and documentation of vascular reconstruction in the extremities. Transvenous Xeroarteriography is a really noninvasive, painless and easy to handle method whiich allows visualization of peripheral vascular lesions and can be reproduced at short intervals without any risk.
