Vascular clips can be used in bypasses at risk of future occlusion, to assist with catheter placement for radiological intervention. We explain how vascular clips can be placed as a landmark for the sites of anastomosis. After completion of the vascular anastomosis, two or three bullets of medium-sized vascular clips are clipped to the tips of the vascular suture. The sites of the vascular anastomosis are checked by plain X-rays. Finding the inlet of the anastomosis in an occluded graft can be difficult, and the marker proved helpful for introducing the guide-wire through the inlet of the site of anastomosis. The vascular clips around the popliteal anastomosis enabled us to clearly differentiate above-knee from below-knee femoropopliteal bypasses using plain X-ray postoperatively. This is a simple yet effective method of identifying the site of vascular anastomosis. Thus, we recommend using vascular clips as a landmark to aid in postoperative intervention by allowing clear identification of the level of anastomosis.
