Figure 3a. Technique for gastroduodenal stent placement. (a) Anteroposterior radiograph shows an angiographic catheter crossing a stricture in the antrum (arrows). The stricture is localized with contrast material injected through the catheter. (b) Anteroposterior radiograph shows a superstiff guide wire (arrow) that has been advanced into the jejunum. The delivery system for the stent (arrowheads) is advanced over the guide wire and centered in the stricture. (c) Anteroposterior radiograph obtained after stent deployment shows a partially expanded stent (arrows). Note that the center of the stent is compressed by the tumor. (d) Anteroposterior radiograph shows a 10-F introducer sheath (arrow). Contrast material is injected through the sheath to assess the position of the stent. (e) Anteroposterior radiograph obtained 1 day after the procedure shows almost complete expansion of the stent. Note the decompression of the stomach.
