Technical Pitfalls and Hints

Occasionally, during a GI bleed, contrast may "track" in between the bowel mucosal folds creating a "pseudo-vein sign." If one sees a linear or gently curved "abdominal vessel" during an arteriogram that has the angiographic appearance of a vein (or follows the course of mucosal folds), be suspicious for a site of bleeding. In a brisk bleed, extravasated contrast may also track along the dependent region of a hollow viscus.

It is useful to place an angiographic sheath in the common femoral artery. The sheath can be flushed with heparinized saline and kept in place while the patient is in the ICU. In the event of GI tract rebleeding, percutaneous access is already present.

During infusion of vasopressin (which may last 1 to 2 days), it is useful to cover the percutaneous puncture site with a sterile adhesive clear dressing. (The clear dressing allows the nurses and physicians to clinically evaluate the region for possible groin hematoma formation).

Intravenous antibiotics are generally administered during transcatheter procedures (ie, vasopressin infusions or embolotherapy).
