Upper Gastrointestinal Bleeding Due to a Left Gastric Artery Pseudoaneurysm: A Case Series

Ultrasound-guided percutaneous coil and thrombin embolization of a left gastric artery pseudoaneurysm

Pseudoaneurysms are a commonly encountered pathology, though pseudoaneurysms of the visceral arteries are a less frequent, but potentially deadly entity. Transarterial embolization is the typical treatment of visceral pseudoaneurysms, but success is dependent on anatomy that is conducive to selecting the supplying vessel. Abdominal ultrasound is a viable method to effectively treat visceral pseudoaneurysms when transarterial embolization is not possible. It is also an excellent example of the growing utilization of ultrasound guidance in various interventional radiologic procedures. The usefulness of ultrasound is demonstrated in this case report, where a left gastric artery pseudoaneurysm was embolized through ultrasound guidance.

A Rare Case of a Gastric Ulcer Causing Left Gastric Artery Pseudoaneurysm

Upper gastrointestinal hemorrhage is an uncommon but can be a lethal presentation of a pseudoaneurysm because a rupture is associated with a 40%–80% mortality rate. We report a rare case of left gastric artery pseudoaneurysm secondary to peptic ulcer disease presenting as an upper gastrointestinal hemorrhage.
