Pitfalls in histoacryl glue injection therapy for oesophageal, gastric and ectopic varices: A review

Figure 1 Endoscopic images of a gastric varix before and after glue therapy. The varix has become smaller and is now firm when probed. The plain radiograph between demonstrates a radio-opaque deposit in the fundus of the stomach, due to lipiodol.

Figure 2 Duodenal varix on computed tomography and plain radiograph before and after glue injection. A: Computed tomography angiogram showing a large abdominal varix meeting the duodenum (white arrow); B: After glue injection a plain radiograph showed lipiodol/glue in the same vessel, with extension medially up to the portal vein (black arrow).

Figure 3 Computed tomogram of brain following glue/lipiodol injection. There are high signal deposits peripherally following embolisation of glue.

Figure 4 Endoscopic appearances of oesophagus following glue injection for refractory variceal haemorrhage. There is ulceration and early cavitation in the first image which progresses and is severe 5 d later.
